Description

  The present invention relates to a stereoscopic video distribution system, a stereoscopic video distribution method, a stereoscopic video distribution device, a stereoscopic video viewing system, a stereoscopic video viewing method, and a stereoscopic video viewing device.

  As an encoding technique for compressing a digital video signal progresses, it is possible to realize an optical disc apparatus excellent in searchability and operability by recording the compressed video signal on an optical disc. Such an optical disc apparatus records video as a digital signal, so there is no deterioration due to dubbing compared to the case of recording an analog video signal, and it is optical recording and reproduction, so it is non-contact and excellent in reliability.

  On the other hand, as an encoding method for compressing data of the digital video signal as described above, for example, there is a method based on the MPEG (Moving Picture Coding Experts Group) method, but this compression method is compared with an in-plane compression method such as motion JPEG. Although the compression efficiency is good, since motion compensation prediction in the time direction is used, it is possible to search only in units of video (GOP) consisting of a plurality of video groups, and access on the disk is also made to I picture consisting of in-plane compression. There were constraints such as having to access first. Therefore, Patent Document 1 proposes to devise a data format on the optical disc.

  Further, the data format of Patent Document 1 is only for filing a two-dimensional plane image. When a 3D image is filed, the right and left eye images are separately displayed in the first and second fields of the TV signal, and the two images are displayed only by the respective eyes with deflection glasses or the like. It is necessary to adopt the method of Patent Document 2.

  In addition, as a method of putting a stereoscopic image on a server and displaying it, there is a description in Patent Document 3, but this is to display an advertisement in a three-dimensional manner by rotating and displaying the image. The method using a plurality of cameras is merely a device in which a stereoscopic image is displayed using a rotated image. On the other hand, as a method for generating a moving image character in the server, a method of uploading a three-dimensional image to the server using left and right images is described in Patent Document 4, and a medical three-dimensional image rendering at the time of remote operation Although there is description in Patent Document 7 as a processing method, there is no description of a signal format or the like when delivering a stereoscopic video to a server. Patent Document 6 describes the conversion of 2D video to 3D video in the video information sending means, but does not describe a specific conversion method or the like. Further, although methods disclosed in Patent Documents 8 and 9 for realizing a stereoscopic virtual realization space are not related to a system or signal format for stereoscopic viewing of video content in this case.

  Various methods have been proposed as a signal format for viewing stereoscopic images, such as a method of transmitting and compressing left and right images respectively, a method of dividing the screen into both sides, and a method of dividing the screen up and down. . Therefore, there are many methods as the original video of the video content to be distributed, and it has been difficult for the video distribution servers owned and serviced by each company to be unified to a specific method.

  In addition, there has been a demand for a method that can handle a plurality of servers having different systems in an integrated manner including accounting processing.

  Also, even in the user viewing environment, even when the video distribution source server owns the stereoscopic video content, it is not always in a state where stereoscopic viewing is possible as the user viewing environment. In such a case, even if the normal 2D video viewing TV looks like a double copy or is a 3D viewing TV, the same problem occurs when the setting of the TV is a flat video viewing setting. .

  Also, in the content viewing menu, it is necessary to distribute separate menus such as those that do not include 3D content depending on whether a stereoscopic viewing environment is possible or only planar video can be viewed. There was a problem that could not be done without recognizing.

  In addition, with regard to the distribution of multi-angle video, there is a problem that the response to the angle switching instruction from the device is slow, and it is impossible to cope with such as viewing the content to be viewed by rotating the angle.

  In addition, when viewing widget information on a TV screen in an overlay or divided screen, if the widget information created for 2D video is displayed as it is in the 3D video, the position in the depth projection direction is always fixed at the default position. There is a problem that it is difficult to view, for example, when widget information with a sense of incongruity that appears to be located in the back is viewed when the entire video is popping out.

  In addition, ordinary video distribution contents are generally mostly flat images, but for users who have a stereoscopic viewing environment, there is a demand for a method for viewing two-dimensional images in three dimensions. Considering the safety of viewing such as fatigue, there has been a demand for a method of changing the amount of projected video.

  In addition, there is a need for a method of viewing two-dimensional content that the user has personally recorded with a movie or the like in a three-dimensional manner, and other people can easily view it even when the personal content is uploaded. There was a problem.

(Embodiment 1)
Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the overall configuration of the stereoscopic video system according to the present embodiment. In the stereoscopic video system shown in FIG. 1, a stereoscopic video recording device 6 (hereinafter also simply referred to as a recording device 6), a TV, a projector, or the like that reproduces media on which stereoscopic video is recorded and outputs right-eye video 1 and left-eye video 2. Display device 3, a liquid crystal shutter or the like, which can be switched between two transmission polarizations, and a liquid crystal shutter on the left and right or a different polarization on each of the left and right to view the images 5A and 5B in the frame order via the shutter 4. It is comprised with the spectacles 7A with which the board was comprised. FIG. 2 shows another configuration example of the stereoscopic video system according to the first embodiment. The stereoscopic video system shown in FIG. 2 differs from FIG. 1 in that it includes two display devices A and B, and projects on polarizing plates 9 and 10 for allowing only light of specific polarization components having different directions to pass through, and the display panel 12. For viewing the images 5C and 5D having the frame order obtained through the polarizing plates 9 and 10, and glasses 7B having different right and left polarizing plates.

  FIG. 3 shows still another configuration example of the stereoscopic video system according to the first embodiment. In the stereoscopic video system shown in FIG. 3, unlike FIG. 1, a synchronous rotating member 13 having a circular rotating disk on which semicircular polarizing plates that pass only light of specific polarization components having different directions are bonded, and the synchronous rotating member 13. And a light source 14 for projecting light. FIG. 4 shows still another configuration example of the stereoscopic video system according to the first embodiment. The stereoscopic video system shown in FIG. 4 includes display devices 15 to 19 for projecting a plurality of videos based on the video signal 22 and a rotating mirror 21 for reproducing the projected stereoscopic video, unlike FIG. ing.

  FIG. 5 is a trial of a stereoscopic image perceived by a human. In FIG. 5, the depth positions 117 to 117 are arranged in order from the infinite distance 111, and the depth position 117 is the position where it protrudes most (close to the eyes). Further, FIG. 5 shows a person 118 displayed on the depth position 115, a person 119 displayed on the depth 114, a river 120 flowing from a distant place, and a mountain 121 visible in the distant place. FIG. 6 is a further display of subtitle display in addition to the display of FIG. 5, and illustrates subtitles 122 </ b> A to 122 </ b> C displayed at respective depth positions and depth ranges 123 </ b> A to 123 </ b> C of the subtitles.

  FIGS. 7A and 7B are diagrams showing the angular change acceleration of parallax, the time and number of changes, and the degree of eye fatigue. In FIG. 7A, the eye fatigue level 124 is the vertical axis, the product 125 of the angular change acceleration / change is the horizontal axis, the eye fatigue level 126 for the attention point and caption, the highest fatigue point 127 for the attention point and caption, The background image eye fatigue level 128, the limit point 129 at which background sickness occurs, the human eye safety area 130, the human eye danger area 131, and the human eye 3D sickness area 132 are respectively illustrated. Show. FIG. 7B is a schematic diagram for showing the parallax movement of the eye. The image 126A far from the point of interest, the image 126B near the point of interest, the viewing angle 126D when near, and far away. In this case, the viewing angle 126E, the human eye 126F, the depth 126G where the video 126B is displayed, and the depth 126H where the video 126A is displayed are illustrated.

  FIG. 8 is a graph showing the relationship between the acceleration in the depth direction of the point of interest and the movement time × number of times. In the graph shown in FIG. 8, the vertical axis is the acceleration 133 in the depth direction of the point of interest, the horizontal axis is the product of the movement time and the number of times (movement time × number) 134, the boundary 135 between the safety area 130 and the danger area 131, the danger area A boundary 136 between 131 and the 3D sickness generation region 132 is illustrated. FIG. 9 shows the relationship between the depth position and the depth position change amount in subtitle display. In FIG. 9, with the depth position 137 as the vertical axis and the depth change amount 140 as the horizontal axis, the infinity position 138, the eye position (frontmost) 139, the depth change amount limit value 141, the front depth limit (jump limit) ) 142 and a remote depth limit 143 respectively.

  Here, in general, stereoscopic video systems using a TV or a projector, as shown in FIGS. 1 to 3, often use parallax information of human eyes, and each video information is displayed on the left and right with glasses. It is projected and shown in three dimensions. In general, when shooting a video, two cameras are used to shoot a video for input to the left and right eyes. Here, first, the left and right video information stored in the recording device 6 is input to the display device of the TV or projector. At this time, when the analog interface is used as the information interface between the recording device 6 and the display device, it is necessary to transmit information separately on the left and right sides. In addition to serial transmission, there is a method of compressing and transmitting on the recording device 6 side and decompressing on the TV side. Also. In the case of TV display, left and right video information is displayed by switching between left and right for each field. However, when a TV using a double-scan display in recent years is used, a playback video is divided into left and right for each field. Problems such as flicker can be solved, and smooth stereoscopic video playback is possible.

  Furthermore, as shown in FIG. 1, when the shutter 4 configured by liquid crystal or the like and capable of switching between two transmission polarizations is configured, the transmitted field image 5A is, for example, vertically polarized light, and the image 5B is horizontally polarized light. By controlling the shutter 4, the polarization angle of light for each field can be changed. In this case, the glasses 7A side may be attached with different polarizing plates (vertically polarized light and horizontally polarized light), and a signal corresponding to the timing at which the display device 3 controls the shutter 4 via the cable 3A is sent from the display device 3. The cable 3B supplied to the glasses 7A becomes unnecessary. On the other hand, when the shutter 4 is not used, it is necessary to provide a liquid crystal shutter on the side of the glasses 7A, and the field synchronization signal cable of the cable 3B is necessary. When the liquid crystal shutter on the glasses 7A side is used, since polarized light is not used, even if the angle of the glasses changes, such as tilting the neck, the effect on the stereoscopic display can be reduced.

  In the method of FIG. 2, two display devices having a PLD element or a transmissive liquid crystal type are provided, and separate left and right images are displayed on each display device. In this case, polarizing plates 9 and 10 having different polarization directions are attached to the front surfaces of the display devices (A and B) 7 and 8. As a result, the light emitted from the respective display light emitting portions has different polarizations, and is projected onto the display panel 12 via the optical system 11, so that, for example, the right eye is a vertically polarized image 5C and the left eye is It is possible to project a horizontally polarized image 5D. Here, video information with parallax is input to each eye using the polarizing glasses 7B.

  Further, in the method of FIG. 3, a polarization switching mechanism having a synchronous rotating member 13 that rotates in synchronization with the field display timing of the TV is configured in the portion of the light source incident on an optical element such as a PLD so that the field display timing is achieved. In this method, light having combined polarization is incident on a PLD element or the like. In this case, an image having a different polarization for each field is projected on the image display panel. Viewing this with the polarized glasses 7 of the same type as in FIG. 2 makes it possible to see the parallax image. In addition, as shown in FIG. 4, there is also a method for reproducing a stereoscopic image by projecting images taken from a plurality of angles by a plurality of display devices 15 to 19. In this case, it is necessary to store and reproduce a plurality of streams instead of two stereoscopic video streams.

  Further, the synchronous rotating member 13 that rotates in synchronization with the timing of the field display of the TV is configured with an optical filter that passes only specific wavelengths of RGB, and the other half of the disk is for the left eye and the other half is for the right eye. By shifting the RGB wavelengths, the wavelength of the light for the right eye and the left eye is changed, and the left and right images can also be obtained by configuring the glasses 7 with optical filters that pass only the wavelengths for the right eye and the left eye, respectively. It can be incident on each eye. In this case, the left and right RGB shifts can be corrected by color adjustment on the display side of the TV so as not to be inferior in color reproduction. Also, in the method of shifting the RGB wavelength left and right, the glasses 7 can be tilted even if the glasses are tilted. The light from is not attenuated.

  In the method using the rotating mirror 21 in FIG. 4, images from a plurality of viewpoints are projected onto the rotating mirror 21 by the display devices 15 to 19. However, it looks like the real thing (in the extreme case, you can see the hidden parts such as the back side).

  Next, actual stereoscopic video will be described. Even in the case of video reproduction using parallax, it is perceived by human eyes as shown in FIG. In this case, if the depth from the infinity 111 of the depth position to the eye position 117 is decomposed and expressed, the respective images are displayed on the depth plane from the depth positions 112 to 115. For example, a character that is a point of interest looks like a human 118 when it is in front, and looks like a human 119 when separated. The river 121 or the like, which is background information, looks smaller when it is farther away, and the larger mountain 121 or the like appears larger even in the background. For example, when a caption is displayed on a stereoscopic video as shown in FIG. 5, it is expressed as shown in FIG. The subtitle 122A in the vicinity is gradually moved away from the subtitles 122B and 122C. If the depth positions of the humans 119A to 119C, which are the characters of interest, change depending on the scene, if the subtitles are changed accordingly, the movement of the focal point of the eyes is reduced, so that fatigue is less likely to occur. Therefore, it is desirable to display the caption 122A in the scene of the human character 119A, the subtitle 122B in the scene of the human character 119B, and the subtitle 122C in the scene of the human character 119C. Since there is no change in depth position in the conventional 2D video, the distance between the user and the TV is the focus of the human eye and does not move the muscle in the focus direction of the eye, but the stereoscopic video uses parallax. This is because movement of the eye for the amount of parallax is required even if it is a thing.

  Further, as shown in FIG. 7A, in the movement of the attention point of a character or the like in the focal direction, eye fatigue occurs in proportion to the change speed, the time required for the change, and the number of changes. In particular, since the eye must follow the attention point, eye fatigue is intense, and it is considered that the peak of fatigue is reached when the parallax angle change speed, the time required for the change, and the number of changes are small. In particular, the near side image has a large parallax angle like a viewing angle 126D shown in FIG. 7B, and the far side image has a small parallax angle like a viewing angle 126E. When the perspective changes, the parallax angle changes, and both eyes 126F need to focus on the target by setting this angle, and must follow the change in the parallax angle accompanying the change in perspective. In conventional TVs that display flat images, there is no perspective image, so the parallax angle necessary for recognizing the depth direction of the eyes is always constant. The eye burden is increased because the eye movement must be applied. However, if the movement is faster than the response of the eye, it cannot be followed, and the fatigue is also reduced. In addition, although the eye does not originally follow the background information, it is presumed that the degree of fatigue tends to increase as the rate of change of the parallax angle, the time required for the change, and the number of times increase. Figure 8 shows the relationship between the depth direction acceleration and the product of the travel time and the number of times, and even if the depth direction acceleration is small, if the number of times and the distance increase, the occurrence of dangerous areas and sickness can be seen, If the level falls below a certain level, it is estimated that even if the product of the travel time and the number of times increases, the tired state is not obtained.

  Here, the degree of eye fatigue as an evaluation value is such that when the screen size increases, the movement of the eye in the in-plane direction also increases and fatigue increases. Can be considered. First, the evaluation function 1 is such that the evaluation value (the degree of eye fatigue) is parallax angle change speed × time required for change × a <n> It is proportional to the number of changes. The evaluation function 2 is such that the evaluation value (fatigue degree of the eye) changes the parallax angle change speed × the time required for the change × a <n> It is proportional to the number of times x the screen size. When the size of the TV screen can be detected, the evaluation function 2 is used, and when it cannot, the evaluation function 1 is used. In the second and subsequent embodiments, the evaluation value (eye fatigue degree) is described as a depth change degree.

  When one stereoscopic video is produced, the amount of change in the parallax angle of the stereoscopic video in one video content, the time involved in the change, and the number of changes are set as evaluation coefficients so that they do not enter the danger area 131 of FIG. 3D video content can be produced by re-encoding. In addition, by describing the degree of depth change as an evaluation function in this stereoscopic video content as well, the degree of eye fatigue is presented before watching the movie, and the user is allowed to select 2D playback or 3D playback. I can do things. At this time, as a re-encoding method, a shooting device such as reducing a parallax interval of a camera that shoots a parallax image (reducing the distance between two cameras) or a pixel conversion process using parallax information described later. A method of performing image processing that reduces parallax, a method of limiting the pop-out amount at the time of content production with CG, etc. are performed for animation and the like.

  In order to grasp such a story of a movie or the like, for the subtitle display that must be read by the user, it is necessary to limit the amount of change in the depth direction as shown in FIG. This is because if the follow-up speed in the focus direction of the eye becomes too high, eye fatigue increases as shown in FIGS. 7 and 8, and 3D sickness is likely to occur. In addition, since the subtitles at positions that are too far away have a sense of incongruity as shown in FIG. 6 due to the size of the subtitles and the background, it may be better to limit the distant positions. In addition, there is a need to limit the near side near the eyes. This is especially true when the eye is too close to the eyes, because the eye angle changes greatly because of the viewing angle, and the eye fatigue is increased. Because there is also. In addition, when the TV screen to be displayed is enlarged, the amount of eye movement in the in-plane direction is increased, and the psychological effects such as “surprise” and “surprise” described above are also increased. desirable. When the playback device and the TV are linked, information regarding the size of the TV screen is exchanged with the playback device, and the pop-up range limitation of subtitles and the like is severely limited. In addition, when a plurality of streams with different pop-out amounts are arranged, a configuration in which a stream with a small pop-out amount is selected when the TV screen is large, and a stream with a large pop-out amount is selected when the TV screen is small is considered. It is done. In addition, when the pop-out amount can be changed by setting on the apparatus side described later, it is conceivable that the setting is automatically performed in consideration of the TV size information and the user status (age etc.).

  At this time, a stereoscopic video parental level consisting of the above evaluation value and the maximum projection amount that is the viewing angle is specified, and according to the stereoscopic video parental level, the age limit for viewing and the danger notification for the elderly and the sick are to be given. Is possible. For example, as a stereoscopic video parental level, level 1 is assumed to be fatigue / dangerous, evaluation value (eye fatigue)> c, maximum pop-up amount> d, and normal parental level is high. Level 2 indicates that fatigue / risk is slightly high, and evaluation value (eye fatigue level)> c, maximum pop-up amount> d, normal parental level is below normal, or evaluation value (eye fatigue level)> e , Maximum pop-out amount> f, normal parental level is high. Level 3 assumes that fatigue / risk is medium, evaluation value (eye fatigue degree)> e, maximum pop-out amount> f, and normal parental level is below normal. Level 4 is assumed that there is no fatigue / danger, evaluation value (eye fatigue)> g, maximum pop-out amount> h, and normal parental level is below normal.

  In the example of the stereoscopic video parental level described above, there is a relationship of c> e> g, d> f> h, and the normal parental level (planar image parental level) is the current level for horror movies and the like. This refers to the viewing restriction for safety defined in the 2D video DVD and the like. In addition, such 3D image parental level settings can be set / changed at the time of product purchase or at the initial setting.For example, by storing the PIN number, it is possible to change the release later. More useful.

(Embodiment 2)
Next, the second embodiment will be described below with reference to the drawings. For stereoscopic images using parallax information as shown in FIG. 1 to FIG. 3, if a TV broadcast is made as it is, a screen like a double copy is displayed, and viewing is not performed unless a dedicated stereoscopic display device as described above is configured. I can't. Therefore, since performing stereoscopic video in broadcasting depends on the equipment infrastructure on the viewer side, a dedicated channel that cannot be generally viewed is provided, or a flag indicating that it is 3D video is superimposed on broadcasting information, etc. Is required. For this reason, it is normally distributed on a recording medium or the like, and it is convenient to view it on a dedicated player or a player equipped with this function. In this situation, a method and format for storing the above-described stereoscopic video on a recording medium will be described below.

  FIG. 10 shows a recording medium 26 according to the second embodiment. It goes without saying that the recording medium (video medium) according to the present invention may be an HDD medium in addition to an optical disk medium such as a DVD, BD, HD-DVD, or MO. In the case of an HDD, it is often impossible to carry it by itself, but it is advantageous in terms of capacity when recording broadcast 3D video information. On the other hand, in an optical disk medium such as a ROM medium, it is effective for distributing stereoscopic killer content before broadcasting or stereoscopic charged content. In the disc-shaped recording medium 26 shown in FIG. 10, an area for confirming control information related to video information (video control information 23), an area for storing stereoscopic video (video title 24), and a normal 2D video are stored. Are divided into areas (video title 25).

  FIG. 11 shows an example of the structure of the video stream of the video title (video content) 24 part of FIG. In FIG. 11, the video title 27 is 2D video information 28, 2D video information 30 and 31 that can be selected by the user, and 3D video information that is automatically selected or selected by the user when the display device can display stereoscopic video. 29, 2D video information 32 reproduced following the video information 29-31, and last 2D video information 33 of the video title 27. In FIG. 11, as the GOP layer stream information, the supplementary information area 34 in which supplementary information related to the GOP video information is described at the top of the following GOP video information 35 and 36 is described, and the top of the GOP video information 38. A supplementary information area 37 in which supplementary information related to GOP video information is described, and a supplementary information area 39 in which supplementary information related to GOP video information is described at the top of the GOP video information 40 and 41 are illustrated. Yes.

  In FIG. 11, as stream information of the picture layer, the packet data part 42 describing the accompanying information, the I picture data 43 composed of the in-plane encoded data, the I picture data 43 and the P picture 45 in the time direction. A B picture 44, which is predicted encoded data, and a P picture 45, which is encoded data predicted in only one time direction from the I picture data 43, are illustrated. In FIG. 11, as the transport packet data layer, the same packet 46 as the packet data part 42 in the transport packet data part describing the incidental information, the first packet 47 obtained by dividing the I picture data 43 by the transport packet, A transport packet 48 in which the last data of the I picture data 43 is stored, a last portion 49 of the I picture data in the transport packet 48, and a padded portion 50 in the transport packet 48 are illustrated. Yes.

  FIG. 12 shows a data structure of a hierarchy of areas in which 3D video information 29 and 2D video information 30 and 31 in the video title (video content) 27 can be selectively selected. In FIG. 12, supplementary information 51 storing information related to the main video sequence arranged at the head in a region where 3D video information 29 and 2D video information 30 and 31 can be selectively selected, and a GOP video information sequence in the region. 52, additional information 53 in which information related to the GOP video information sequence 54 is stored, and additional information 55 in which information related to the last GOP video information sequence 56 in the area is stored are illustrated. In addition, in FIG. 12, as picture layer stream information, I picture data 57 composed of in-plane encoded data, and P picture which is encoded data predicted in the time direction from I picture data 57 and P picture 59 58, a B picture 59, which is encoded data predicted from the I picture data 57 in the time direction of only one direction, is illustrated.

  Also, in FIG. 12, as the transport packet data layer, the first packet 60 obtained by dividing the I picture data 57 by the transport packet, the transport packet 61 in which the last data of the I picture data 57 is stored, the transport packet The last part 62 of I picture data in 61 and the padded part 63 in the transport packet 61 are shown. In addition, an arrow A shown in FIG. 12 is a playback part, an arrow B is a part that jumps when 3D playback is performed, and an arrow C is a part that is played back to perform 3D playback. The GOP video information is arranged. FIG. 13 shows the data structure of the area hierarchy in which the 3D video information 29 and 2D video information 31 in the video title 27 can be selectively selected, and is basically the same as FIG. Are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIG. 10, the structure of data recorded on the optical disk or HDD medium includes an area of video control information 23 in which video-related supplementary information and sequences are recorded, and actual video titles (video contents) 24 and 25. It is composed of At this time, the entire 3D video is not necessarily a 3D video, and a case where the 3D video is mixed with a 2D video or a case where these videos are switched by a user's selection is assumed. In particular, in the DVD standard, it is possible to switch and display a user-selectable video information sequence such as multi-angle, and even in the case of 3D video information, it is considered that not all user devices are compatible with 3D video. Then, a 3D video stream is additionally constructed on the 2D video stream. When the user's display device is 3D-compatible, the 3D video stream is automatically identified by the link function of the HDMI terminal and the 3D video stream is selectively displayed, or the 3D video side is selectively determined by the user's button operation. A method of making it possible is conceivable. Of course, it is needless to say that all content may be in 2D video only or 3D video only, but the format requires consideration for such a composite format.

  Also, in the video information stream of the video title 24, it is desirable to provide an associated information area on the video information stream so as to perform access and management of information, switching of device settings, and the like. In particular, in a content in which 2D video and 3D video are mixed, it is necessary to determine whether the video stream is 2D video or 3D video on the TV side. It is possible to easily and automatically switch the setting on the side. When all settings are closed by a player / recorder that reproduces or records a recording medium, the control information may be described only in the video control information 23 arranged in a part of the disc. However, in the case of connection coordination with a TV, especially when a procedure such as switching the TV during playback is performed, automatic control on the TV side is performed by superimposing the minimum necessary control information on the video information itself. Change setting can be performed. When there is no control information in the video information, the TV connection switching is detected, the control information is separately transmitted from the player / recorder, the TV side setting is changed, and then the video information is transmitted. These TV-side setting changes are performed on the display device side, such as switching the polarization of the stereoscopic video reproduction itself, so that it is necessary to have a mechanism for quickly performing the setting change processing of the display device. Absent.

  The incidental information 51 can also be used for information access management, and is fixed as Navi information in the DVD standard. Here, when 2D video and 3D video are mixed, the time series of the contents are arranged in parallel, such as 3D video information 29 and 2D video information 30 and 31 shown in FIG. Therefore, the supplementary information 34 at the head needs to be arranged at the head of the GOP data information group. First, by reading the content of the supplementary information, whether the information of the next GOP sequence is 2D video or 3D video, In the case of a 3D video, it is possible to determine whether the video is a left-eye video or a right-eye video, and arrangement information (where to access) in the GOP video information group. Here, the GOP video information group including the accompanying information 51 at the head is defined as a video unit that is larger than the GOP video information as a video unit.

  In addition, in the case of video information data that is also compressed in the time direction, such as MPEG, information exists in units of GOP video information starting from an I picture, so that video data access is in units of this GOP video information. Needless to say. Also, since the incidental information needs to be read first, it must be placed at the beginning of the GOP video information group. For example, when reproducing the 3D video information portion as shown in FIG. After the middle arrow A), the 2D video information 30, 31 is jumped to reproduce the 3D video information 29. At this time, the 2D video information 30, 31 jumps as indicated by an arrow B in the figure, and unnecessary memory is increased by preventing unnecessary information (in this case, 2D video information 30, 31) from being taken into the memory of the playback device. The 3D video information 29 indicated by the arrow C in the figure is reproduced so as to avoid this and prevent the video from being interrupted.

  Further, the supplementary information 51 at the head of the GOP video information is arranged at the head position of the I picture 57 in the state of the picture layer below it. Further, since it is convenient to divide these compressed video data into transport packets in order to have compatibility with digital broadcasts such as terrestrial waves and satellites / cables, the lowermost layer data is shown in FIG. The transport packets 60 and 61 are divided as follows. Even in this case, the incidental information 51 is described in the first transport packet of the GOP video information group 52. Needless to say, a newly defined private packet in the transport packet is used. Further, since the last transport packet 61 of the GOP video information group is not necessarily cut off in a certain transport packet unit, the last portion 63 is padded with “00” or “FF” to obtain the GOP video. It is preferable to complete packet data in units of information. Also, as shown in FIG. 13, when one 2D video 31 and one 3D video 29 are branched, the amount of GOP video information to be jumped by arrow B in the figure is smaller than that in FIG. The basic operation is the same as in FIG.

  The contents of the accompanying information will be further described. The supplementary information 51 shown in FIG. 14 includes content information 64, time code 65, arrangement information 66, information 67 about video information, information 68 about audio information, and information 69 about OSD information. 14 includes a content name 70, a copyright 71, encryption information 72, presence / absence 73 of 3D video, and valid area information 74.

  Further, the time code information area 65 shown in FIG. 15 includes a presentation time 65A and synchronization information 65B. The arrangement information 66 shown in FIG. 16 includes seamless information 75, jump destination information 76, angle information 77, and intra-GOP arrangement information 78. The video information 67 shown in FIG. 17 is related to resolution information 79, frame rate information 80, 3D video information 81, parental information 82, angle information 83, encryption information 84, information about 3D video format and presence 85, and 3D video frame rate. The information 86 includes 3D video information count 87, depth resolution information 88, depth change information 89, subtitle permission depth information 90, depth restriction information 100, and parallax amount restriction information 101.

  FIG. 18 is a schematic diagram when the supplementary information is displayed on a TV as a display device. FIG. 19A and FIG. 19B are schematic diagrams when multi-angle shooting is performed from a plurality of cameras. The OSD information 69 shown in FIG. 20 includes OSD arrangement information 69A, OSD storage destination information 69B, font and font size designation 69C, in-plane OSD arrangement information 69D, depth direction OSD arrangement information 69E, and depth position. 69F, depth permission limit 69G, and depth zooming speed 69H.

  Here, the supplementary information 51 in FIG. 14 is first described for each GOP video information group on the stream, and is transmitted together with video information even when HDMI transmission is performed to a TV or the like. Therefore, it goes without saying that necessary information is also included in the setting on the TV side particularly regarding 3D video display.

  Next, the content information 64 shown in FIG. 14 will be described. The content name 70 displays (1) content name, (2) performer name, (3) production time, (4) distribution company, (5) related work name, and (6) summary as OSD information on the TV side. There is a case to let you. If the content name 70 includes the accompanying information 51 superimposed on the video stream, the content name 70 can be displayed even when the TV-side input is switched to 3D video information. It becomes.

  The copyright information 71 shown in FIG. 14 includes (7) copyright owner, (8) distributor, (9) importer, and (10) capital participating company, so that the copyright owner of the video stream can be obtained. This information can be distributed at the same time, and even if the reproduction data is used illegally, the copyright holder's right can be claimed. In addition, since this information is superimposed on the video stream, information is always distributed to the TV even when the TV is switched, so that it is possible to display a copyright.

  Further, the encryption information 72 shown in FIG. 14 is (11) presence / absence of encryption and (12) encryption method, so that it is encrypted highly confidential information or no confidentiality such as commercials. Information can be sent to the destination device.

  Also, the 3D video information 73 shown in FIG. 14 includes (13) 3D video compatibility, (14) whether all 2D video is supported (whether playback is possible only by displaying 2D video), and (15) 3D video. In the case of correspondence, it is possible to display to the user that it is not compatible when connected to a TV that does not support 3D video by describing whether or not 3D video playback is prioritized. In addition, when the TV and HDMI are linked, the TV side is automatically switched to 3D video setting (for example, as shown in FIGS. 1 to 3, two video streams are automatically displayed for each field. ) When there is no 3D video function on the TV side, the TV or playback device can display that the TV is not supported, or can take measures such as ejecting the disc.

  14 describes (16) 2D video playback permission area and (17) 3D video playback permission area, thereby not only limiting the playback permission area of this disc, but also 2D video playback. It is also possible to specify a limited area where only video is allowed and 3D video compatible display is allowed. This is because there are cases where only 2D video playback is permitted in a specific region when the license conditions for 3D video playback are not in place. If the 3D video reproduction permission area is not permitted, even if the 3D video display device is connected, only the 2D video is played, or the disc is ejected.

  Next, the time code information 65 shown in FIG. 15 will be described. In the case of video content in which 2D video and 3D video are mixed, even if the switching is performed by the user (for example, 3D video to 2D video), it is continuously played back without interrupting or omitting the flow of video information. I have to let it. In addition, there may be a time search such as going back / forward 10 minutes before the user's instruction. Therefore, it is necessary to record the following presentation time 65A, which is playback time information from the start time of the title of the video, at the beginning of the GOP video information group. It is possible to display the remaining time on the TV side by describing the remaining time information until the end of the title playback or the total title playback time.

  Also, since 3D video is likely to induce eye fatigue as described in Embodiment 1, the time code from the start of 3D video playback (how many 3D videos have been viewed continuously) and the content of this video content You can display how many 3D images you watched in total, and can give a break instruction and danger display to prevent eye strain. Further, when there is GOP video information for each of the right eye and left eye in the 3D video, it is possible to specify a field corresponding to the playback order. That is, the presentation time 65A includes (18) time code (presentation time) from the start of the title, (19) remaining time information until the end of the title playback or the total playback time of the title, and (20) the time from the start of 3D video playback. The code (3D presentation time), (23) total 3D playback time, and (24) left and right video playback order or field designation are described. The synchronization information 65B specifies synchronization of video content and specifies the playback order or fields of left and right videos.

  Next, the arrangement information 66 shown in FIG. 16 will be described. In particular, when 2D video content and 3D video content coexist, it is necessary to skip information unnecessary for reproduction or to describe arrangement information in the GOP video information group at the head position of necessary data. In addition, when performing a special reproduction operation, it is necessary to consider that access from an in-plane compressed image is required first from the characteristics of compressed video in the time axis direction such as MPEG. Therefore, the seamless information 75 records (25) presence / absence of seamless reproduction (up to the next GOP video information group). The jump destination information 76 includes (26) jump destination (forward and reverse directions) address 1, address 2, etc., (27) jump destination time code information 1, time code information 2, etc. (multiple jump destination information) (28) The presence / absence of the jump destination 3D video information is recorded. Note that (28) if there is no 3D video information at the jump destination based on the information on the presence / absence of the 3D video information at the jump destination, the TV setting can be returned to 2D video during stream playback.

  The angle information 77 includes (29) address 1 and address 2 of GOP video information corresponding to a plurality of angles, and (30) time code information 1 and time code information 2 of GOP video information corresponding to a plurality of angles. To be recorded. In the intra-GOP arrangement information 78, (31) address information 1, address information 2, and the like as the arrangement information of P pictures in each GOP are recorded. As described above, by having the seamless information 75, it is possible to sequentially reproduce while connecting necessary angles, and reproduce only the I picture or only the I and P pictures according to the arrangement information in the GOP. Playback during fast forward and fast reverse is possible.

  Next, the video information 67 shown in FIG. 17 will be described. In the video information 67, what is particularly required as stereoscopic video information is shown below. First, the resolution information 79 stores (32) 2D video playback resolution (in-plane direction), PinP image resolution (in-plane direction), and (33) 3D playback resolution (in-plane direction). . In the 3D video presence / absence method 85, (34) presence / absence of 3D and (35) 3D video mode designation (double scan rate designation, polarized glasses not present, liquid crystal shutter not present) are recorded. In the 3D frame rate 86, (36) a frame rate at the time of 2D video playback, and a frame rate at the time of 3D video playback are recorded.

  The number of 3D video information 87 records (37) the number of independent 3D video information streams reproduced in parallel. When there are n different angles, n = angle number is described. Based on this information, the number of angles can be displayed during reproduction, and the angle can be changed according to the selection from the user and recognized by displaying the angle number. The number of 3D video information 87 records (38) the number of 3D video streams and camera information when the left and right videos are sequentially switched. For example, as shown in FIG. 19A, when a video is captured using cameras D to H shifted by five parallaxes, or an animation image or the like is recorded as five parallax video information by CG. The number of these and the interval or angle of each camera are described. As an example of the description of the incidental information, general information-number of images 5-camera interval ** mm, image 1 from camera D 1-angle 1, image 2 from camera E 2, angle 2 from camera F 3-angle 3, camera G The image 4-angle 4 by the camera 4 and the image 5-angle 5 by the camera H are obtained.

  When there are five images shifted by the amount of parallax, the actual angle image is as follows: angle D is image 1 left, image 2 is right, angle E is image 2 left, image 3 is right, angle F is image 3 is left, video 4 is right, angle G is video 4 is left, video 5 is right and 5 pieces of parallax video information. As shown in FIG. You can play it. At this time, it is also possible to rotate the video by sequentially shifting the angle information. Accordingly, each video stream does not indicate one angle information, but new angle information can be constructed by a combination with a video having an adjacent parallax angle. In recent years, with the evolution of CG technology, it has become possible to easily create stereoscopic images with animation images. By preparing such multi-angle parallax information and accessing each by specifying the remote control from the user The viewpoint can be changed by shifting the angle.

  In the depth resolution 88, (39) depth resolution 1, resolution 2 and the like in 3D video are recorded. When there are a plurality of 3D video streams, a plurality of depth direction resolutions are described. For example, when the depth resolution is extremely low due to a CG image or the like and the image moves rapidly in time, the depth can be complemented in the time direction and displayed smoothly based on this information. Depth change degree 89 records (40) depth change degree 1, change degree 2 and the like in 3D video. When there are a plurality of 3D video streams, a plurality of depth direction change degrees are described. In particular, since the degree of change is related to human eye fatigue as shown in the first embodiment, it can be described in order to ensure safety, and can be used for a warning or a break instruction to the user. .

  In the permitted caption depth 90, (41) a permitted caption depth range (maximum viewing angle 1, minimum viewing angle 1, maximum viewing angle 2, minimum viewing angle 2, etc.) is recorded. When there are a plurality of 3D video streams, a plurality of depth direction change degrees are described. With regard to subtitle information, it is necessary to frequently adjust the focus at the subtitle focus position and the point of interest when viewing stereoscopic video, which will be described later. Is required. Depth information should be described as viewing angle information because it is difficult to digitize because the far distance becomes infinite when the actual distance is used. Moreover, since it is meaningless to describe detailed numerical values when it is close to infinity, a lower limit such as omitting the viewing angle of 1 deg or less may be provided. Based on this information, the player sets the depth position of the caption in the OSD display.

  In the depth restriction 100, (42) depth restriction (maximum viewing angle 1, maximum viewing angle 2, etc.) is recorded. A stereoscopic image popping out too close gives a sense of being surprised by a psychological effect. For this reason, the amount of projection of the 3D image itself, not the subtitles, is limited, and effects that are easy on the eyes and considerations that do not surprise the viewers. In this case, as shown in FIG. 17, the player records a viewing angle that is the maximum amount of pop-up in the video content in advance, thereby warning or restricting viewing to a small child or other viewer as shown in FIG. Is possible.

  The parallax amount limitation 101 describes (43) parallax amount limitation (maximum viewing angle 1, minimum viewing angle 1, maximum viewing angle 2, minimum viewing angle 2, etc. during shooting). When there are a plurality of 3D video streams, a plurality of depth direction change degrees are described. This information defines the range of the deviation amount of the reference angle because the parallax reference amount, which is the distance between the two cameras at the time of shooting, differs depending on the distance between human eyes. Thereby, it is possible to grasp in advance a sense of discomfort when a child or the like having a small interval between both eyes views.

  In this way, in order to eliminate the uncomfortable feeling, a method of preparing a plurality of stereoscopic images with different parallax reference amounts in the same video content and selecting them according to the distance between the eyes of the viewer can be considered. In recent years, CG technology has been revolutionized for a plurality of parallax reference amounts, and animation images and the like can be easily changed by a computer. In this case, by describing such parallax amount restriction information in the incidental information, the player prepares selection keys for ** to **, adults, etc. as shown in FIG. Accurate stereoscopic viewing can be achieved by matching the parallax reference amount in the original video content with the viewer. Further, it is possible to avoid eye fatigue caused by viewing a video with a shifted parallax for a long time. Furthermore, in the parental 82, a stereoscopic video parental level corresponding to 3D video is defined in addition to the normal planar video 2D parental level. The parental 82 includes (44A) a planar video parental level (a parental notation equivalent to the current DVD), (44B) a stereoscopic video parental level (the stereoscopic video parental level described in the first embodiment), and Record.

  Also, as shown in FIG. 20, in the OSD information 69, first, arrangement information 69A that is supplementary information of the OSD itself and an OSD information storage destination 69B that describes an address where the information of the OSD itself is stored are recorded. In the OSD display 69, first, the supplementary information is captured and understood by a microcomputer or the like, and then the actual OSD is acquired and displayed by the storage destination information.

  Here, (45) font font and font size are recorded in the information 69C such as font size. In the in-plane arrangement information 69D, (46) font arrangement information (X position, Y position) is recorded.

  The depth direction OSD arrangement information 69E includes (47) depth position 69F, (48) depth permission restriction 69G (to restrict eye fatigue in the first embodiment such as a far restriction position, a near restriction position, a depth variation restriction, and the like. (49) Depth zooming speed 69H (no zooming, zooming speed) is recorded. In addition, by regulating the zooming at a depth zooming speed of 69H, when switching from one subtitle to the next, the depth position is not changed instantaneously, but it is changed so that it zooms little by little, and tired eyes It is for reducing.

  Note that the incidental information in the 3D video information (1) to (43) is distributed together with the video information as being superimposed on the video information stream, but in a different area from the video information itself described below. The same description can be made for the described video control information 23. In addition, since all information can be read at the start of the player, various initial settings can be made, and more information can be described than superimposed on video information without being limited by bit rate or memory. Therefore, it is possible to describe more detailed control information.

  Next, the structure of the control information arranged separately from the video information in a certain area of the recording medium will be described. FIG. 21 is a diagram for explaining in detail the GOP table portion of the video control information 23 arranged together and the video-related information therein. The video control information 23 shown in FIG. 21 includes content information 64, copyright 71, encryption information 72, 3D video presence / absence 73, valid area information 74, GOP table information 102, sequence information 103, menu information 104, and menu OSD data. 105. The GOP table information 102 is in a table format as shown in FIG. 21 and includes GOP number, logical address, time code, sequence, arrangement, video, audio, and OSD fields.

  FIG. 21 particularly shows the configuration of the video column, which includes resolution information 79, frame rate information 80, 3D video information 81, parental information 82, angle information 83, and encryption information 84. Furthermore, in FIG. 21, 3D video information 81 includes 3D video format information and presence information 85, 3D video frame rate information 86, 3D video information number 87, depth resolution information 88, depth change information 89, subtitle permission information It is illustrated that the information includes information 90 related to depth, information 100 related to depth restriction, and information 101 related to parallax amount restriction.

  FIG. 22 is also a diagram for explaining in detail the GOP table portion of the video control information 23 arranged together and the video related information therein. FIG. 22 particularly shows the configuration of the OSD column, which is configured by the presence / absence 106 of subtitles and OSD information 69. The OSD information 69 includes OSD arrangement information 69A and OSD storage location information 69B. The OSD arrangement information 69A includes font and font size designation 69C, in-plane OSD arrangement information 69D, and depth-direction OSD arrangement information 69E. The OSD arrangement information 69E in the depth direction includes a depth position 69F, a depth permission limit 69G, and a depth zooming speed 69H.

  FIG. 23 illustrates the structure of the sequence information of the video control information arranged together with the video information in a certain area of the recording medium. The sequence information 103 is recorded in a table format. Show. In the video column of FIG. 23, resolution information 79, frame rate information 80, angle information 83, 3D video information 81, and parental information 82 are recorded. The 3D video information 81 includes information 85 regarding 3D video format and presence / absence, information 86 regarding 3D video frame rate, number 87 of 3D video information, information 100 regarding depth limitation, and information 101 regarding parallax amount limitation. On the other hand, subtitle presence / absence 106, subtitle font / color 107, subtitle display method 108, subtitle display depth limit 109, and subtitle data address 110 are recorded in the OSD column of FIG.

  Regarding the control information arranged separately from the video information in a certain area of the recording medium, all information including the information of the supplementary information 34 and 51 superimposed on the video information stream is described. This is because the control information is first read and various initial settings are made when the player / recorder is started up.

  First, the video control information 23 is described as shown in FIG. 21, and the content information 64, the time code 65, the arrangement information 66, the information 67 about the video information, and the supplementary information 51 superimposed in the video information of FIG. It includes information 68 related to audio information and information 69 related to OSD information. However, in the video control information 23 that can store more information, table information relating to all GOPs such as the GOP table 102 can be described, and it is possible to grasp the information content in units of GOP video information without video playback. Is possible. Here, since the GOP table 102 is described as the table in FIG. 21 and has a logical address, the data / file identification information is detected from a signal read from a predetermined sector area, and the detected data is detected. Based on the file identification information, the position where the data file corresponding to the coding unit at the position indicated by the position identification signal is recorded on the disk medium is identified. The data file is read based on the identified position on the disk medium, and the image signal is reproduced by decoding the signal encoded in the encoding unit included in the read data file. Can do. As a result, it is possible to easily identify and reproduce the position where the coding unit at the desired time is recorded.

  Further, in the GOP table 102, the auxiliary information of the same items as the items described in the video streams (32) to (43) including the 3D video information in the auxiliary information regarding the video is described for each GOP video information. Is possible. Also, with regard to subtitle information, as shown in FIG. 23, subtitle presence / absence 106, subtitle font / color 107, subtitle display method 108, subtitle display depth limit 109, and subtitle data address 110 are described (44) to (49). Subtitle supplementary information can be written in units of GOP video information with the same information as that shown in FIG.

  The video control information 23 can also include sequence information in units of GOP video information as shown in FIG. Thus, at the start of playback, a sector address of a predetermined sector area in which information indicating the playback order of the data file is recorded is generated, and the playback order information is read from the data read by the data reading means. Information is detected, and then a sector address is generated based on the reproduction order information. Thereby, it is possible to reproduce an image signal recorded in sectors distributed on the recording medium. The incidental information shown in the above (32) to (49) can also be described in such sequence table information.

(Embodiment 3)
Next, the third embodiment will be described below. FIG. 24 is a block diagram of the stereoscopic video recording apparatus according to the third embodiment. The stereoscopic video recording apparatus shown in FIG. 24 has an AD converter 146 for digitizing video signals of right-eye video and left-eye video of stereoscopic video using parallax information, and movements necessary for image compression in the time direction. A vector detection (motion detection) 147, a DCT conversion circuit 148 necessary for in-plane compression, an adaptive quantization circuit 149 necessary for in-plane compression, and an inverse quantization circuit 150 in the local decoder are provided. Further, the stereoscopic video recording apparatus shown in FIG. 24 stores a variable length coding circuit 151 necessary for in-plane compression, a DCT inverse conversion circuit 152 in the local decoder, a frame memory 153 in the local decoder, and the compressed data. A buffer memory 154, an OSD information encoder 155, an audio encoder 156, a format encoder 157, a modulation means 158 for generating a signal to be written to the optical disk 165, and an LD modulation circuit 159. Further, the stereoscopic video recording apparatus shown in FIG. 24 includes an address header recognition circuit 160 for extracting an address to be recorded on the optical disk 165, a reproduction amplifier 161 for reproducing a signal from the optical head 164, an optical head 164, A servo circuit 162 for controlling the feed motor 163 and the rotary motor 166 and a system controller 167 for controlling and managing the sequence of the entire apparatus are provided.

  FIG. 25 is a diagram showing a stream structure of a stereoscopic video signal generated based on the stereoscopic video recording apparatus of FIG. The stream structure of the stereoscopic video signal shown in FIG. 25 is a structure in which the structure of the right-eye video GOP 168, the left-eye video GOP 169, information 68, and OSD information 69 is sequentially repeated after the auxiliary information 51. The right-eye video GOP 168 shown in FIG. 25 includes a GOP header 170, picture headers 171, 173, I picture data 172, and B picture data 174. Further, the GOP header 170 shown in FIG. 25 includes a user data start code 175 in the GOP header 170 and 3D video information 176 in the GOP header 170. Furthermore, the 3D video information 176 shown in FIG. 25 includes information 177 indicating whether the video is left-eye video or right-eye video 85, information 85 regarding 3D video format and presence / absence, information 86 regarding 3D video frame rate, 87 regarding the number of 3D video information, depth limitation It consists of information 100 and information 101 related to the parallax amount restriction.

  FIG. 26 illustrates a lower structure portion of the stream structure of the stereoscopic video signal generated based on the stereoscopic video recording apparatus of FIG. In FIG. 26, the transport stream packets 178 to 182 of the GOP 168 for the right eye video are shown, and the transport stream packets 185 to 188 of the GOP 169 for the left eye video are shown. The last data of the transport packets 182 and 188 in which the last data of the GOP video information is described are data 183 and 189, respectively, and padded portions 184 and 190 are added to the data 183 and 189, respectively. .

  Here, the stereoscopic video recording apparatus shown in FIG. 24 performs the same video compression for each of the left eye and the right eye. The right eye video digitized by the AD converter 146 is converted into each video by the process of the motion detection 147. A motion vector for each macroblock is extracted. In addition, since the video data is first subjected to in-plane encoding processing, after DCT conversion by the DCT conversion circuit 148, it is quantized by the adaptive quantization circuit 149, and variable length encoding is performed by the variable length encoding circuit 151. Sent to the buffer memory. At this time, the video data after adaptive quantization is restored to the original video signal by the local decoder by the inverse quantization circuit 150 and the DCT inverse transformation circuit 152, and further compared with the video compensated for motion in the frame memory 153, It is possible to perform compression using only the difference information in the subsequent screen for performing compression in the time axis direction. Such compression methods are MPEG and H.264. It is a basic method in the compression method such as H.264 and is widely used.

  Here, in FIG. 24, the right-eye video and the left-eye video are input as independent video streams, and are encoded by separate encoding blocks. Therefore, in FIG. 24, the right eye and the left eye have a structure in which the same blocks are arranged in parallel. However, it is also possible to arrange a memory in the input part and temporarily store the left-eye video and the right-eye video, then process the same encoding circuit at double speed and perform the same processing with one encoding block. The encoded stereoscopic video information is additionally recorded in the buffer memory 154 with OSD information from the OSD encoder 155, audio information from the audio encoder 156, and additional information necessary for formatting from the format encoder 157, and an optical disk 165 as a recording medium. It is arranged in the data format to record. Here, the format encoder 157 additionally records incidental information necessary for recording the 3D video information according to the present invention in addition to the Navi information and menu information necessary for the conventional optical disc format.

  The video data in the format recorded on the optical disc is added with an error correction code as information to be physically written on the optical disc 165 by the modulation means 158 and modulated, and mounted on the optical head 164 by the LD modulation circuit 159. A signal for modulating the modulated laser is generated. At this time, the servo circuit 162 for stably recording on the optical disk 165 controls the feed motor 163 that moves the optical head 164, the rotation motor 166 that rotates the disk 165, and the objective lens actuator in the optical head 164 to adjust the track. And focusing. Further, it is necessary to read an address on the optical disk 165 at the time of recording. A minute signal obtained by photoelectrically converting a signal received by an optical head is reproduced by a reproduction amplifier 161, and address information is generated by an address header recognition circuit 160. These address information is processed in sequence by the system controller 167 together with the activation setting of each block. Particularly, write timing processing that requires high-speed timing is performed by dedicated hardware, and the sequence setting portion that requires programming is a CPU or the like. Done in

  Here, the video stream generated by the stereoscopic video recording apparatus has the structure shown in FIG. First, the compressed video data including the compressed video in the time axis direction such as MPEG includes an in-plane compressed code video generally called GOP. For example, it is configured as a video block of about 15 pictures. Since there are two right-eye video blocks and left-eye video blocks using disparity information here, the GOP 168 of the right-eye video and the GOP 169 of the left-eye video are sequentially arranged with the accompanying information 51 as the head. Note that the right-eye video and the left-eye video each show an example of 1 GOP, but a plurality of GOPs may be used as long as the number of GOPs is the same as long as the video conditions do not change. Further, the incidental information 51 is as described in the second embodiment, but here, it is also possible to define a new user data start code in the GOP header portion and describe the 3D video information 176 after that. is there.

  First, in the 3D video information 176, information (which may be a flag) 177 for identifying whether the video is a left-eye video or a right-eye video is arranged, the presence / absence 85 of the 3D video system described in Embodiment 2, and a 3D video frame The rate 86, 3D video information 87, depth information 100, and parallax amount restriction information 101 are recorded. Also, as shown in FIG. 26, the incidental information 51 is provided with a private packet (TSP1) 178 in the transport packet layer, which is separated and extracted by the transport decoder. With the configuration shown in FIG. 25, the same 3D information can be extracted even at the hierarchical level of MPEG data. When the playback device and TV are linked and automatically set 3D video, or when switching TV during video playback, if the additional information extraction setting in the transport decoder is valid on the TV side, this The information 51 becomes valid, and if the 3D video incidental information in the MPEG layer is valid, the 3D video information 176 becomes valid.

  The video stream shown in FIG. 25 is described in units of MPEG information layers, but FIG. 26 shows that described in units of transport packets one level lower. In FIG. 26, the video data in units of blocks of the GOPs 168 and 169 of the right-eye and left-eye videos starts from the beginning of the transport packet 178 and does not necessarily fit in data that is an integral multiple of the transport packet at the end of the GOP video information. The remaining data in the final transport packet 182 is padded, and the final data 183 is filled with information with padding data 184. Accordingly, it is possible to extract only the GOP 168 of the right-eye video by taking out the transport packet 179 to the transport packet 182. In the GOP 169 of the left eye video, the same processing as that of the right eye is performed, and only the left eye video can be extracted by extracting the transport packet 185 including the padding data 190 from the top of the transport packet 185.

  In the stereoscopic video recording apparatus in FIG. 24, the left-eye video and the right-eye video are encoded as they are. However, the left-eye video and the right-eye video are basically video information that is shifted by the amount of parallax and has a very high correlation. For example, if the left-eye video is configured to record only the difference information from the right-eye video, the entire information amount can be compressed. A block diagram of the stereoscopic video recording apparatus for this purpose is shown in FIG. The stereoscopic video recording apparatus shown in FIG. 27 employs the same configuration as the video compression block configuration shown in FIG. 24 with the block portion of the right-eye video as the main video. However, in the left-eye video, the difference between the output of the motion detection 147 of the left-eye video and the output of the frame memory 153 of the right-eye video is obtained, and only difference information between the left-eye video and the right-eye video is extracted. The difference information is subjected to the DCT transformation 148 and adaptive quantization 149 in the left-eye video line, and the variable-length encoding process 151 is performed, so that only the left-eye video difference information is recorded in the buffer memory 154. The subsequent processing until writing to the optical disc is the same as that in FIG. In the example shown in FIG. 27, the right-eye video is the main video and the left-eye video is the sub-video that takes the difference, but the left and right are reversed (the left-eye video is the main video and the right-eye video is the sub-video). It goes without saying that it is also good.

  In the stereoscopic video recording apparatus shown in FIG. 27, the method of further compressing the video information amount of one side by taking the difference between the left-eye video and the right-eye video has been described, but this video information is based on the parallax information. It is possible to further compress information. FIG. 28A and FIG. 28B schematically show the principle of parallax video. In FIG. 28A, the near-field image object 126G at the depth position 126M, the deep image object 126H at the depth position 126L, and the depth position (frontmost) 126N to both eyes 126F, the viewing angle of the image object 126H. The viewing angle 126E of the video object 126G is 126D. In FIG. 28B, the left eye image 126GA of the image object 126G, the right eye image 126GB of the image object 126G, the parallax amount 126I between the left eye image 126GA and the right eye image 126GB, and the same pixel point 126K of the left eye image and the right eye image. Yes. Further, in FIG. 27B, the left eye image 126HA of the image object 126H, the right eye image 126HB of the image object 126H, the parallax amount 126J between the left eye image 126HA and the right eye image 126HB, and the same pixel point 126L of the left eye image and the right eye image. Yes.

  FIG. 29 is a block diagram of a stereoscopic video recording apparatus that further compresses one video. The stereoscopic video recording apparatus shown in FIG. 29 includes a parallax information calculation circuit 191A for calculating the parallax amount from the left-eye video and the right-eye video, a motion detection circuit 191C in the depth direction, and an estimated parallax information generation circuit 191D. ing. Furthermore, the stereoscopic video recording apparatus shown in FIG. 29 includes a reverse parallax calculation processing circuit 191B for converting the original left-eye video into the right-eye video from the estimated parallax information, and a right-eye video generated by the right-eye video and the reverse parallax calculation processing circuit 191B. Are provided with a DCT conversion circuit 191E that performs DCT conversion, an adaptive quantization circuit 191F, and a variable length coding 191G. Note that the part from the parallax information calculation circuit 191A to the variable length coding 191G is a part that performs the stereoscopic video compression processing.

  FIG. 30 is a diagram for explaining the encoding and decoding of the video stream in the compression method by the stereoscopic video recording apparatus of FIG. In FIG. 30, the parallax information calculation value 193, the left eye video 194A to 194G, the depth direction motion vector calculation value 196, the estimated parallax information 197, and the compressed video 195A to 195G of the right eye main video of the right eye video 192A to 192G, the left eye video It is shown in the figure. Further, in FIG. 30, reproduction main images 198A to 198G based on the compressed images 195A to 195G of the right-eye main image, estimated parallax information 204 to 210 and reproduction sub-images 211 to 217 corresponding to the reproduction main images 198A to 198G, respectively, are illustrated. Has been. FIG. 31 is a diagram showing a video stream structure generated by the compression method by the stereoscopic video recording apparatus shown in FIG. 27 or FIG. The video stream structure shown in FIG. 31 is basically the same as that in FIG. 25, except that the difference video information 218 is used instead of the GOP 169 of the left-eye video and whether the 3D video format presence / absence 85 is GOP video information or difference information. The difference is that information 219 is added. FIG. 32 shows the stream structure at the transport level in the video stream structure generated by the compression method by the stereoscopic video recording apparatus shown in FIG. FIG. 32 is basically the same as FIG. 26 except that it is differential video information 218 instead of the GOP 169 of the left-eye video.

  Here, FIG. 28A shows the stereoscopic direction from the right-eye video and the left-eye video using parallax. In FIG. 28 (a), the parallax angle viewed from both eyes 126F looks different depending on the depth. For this reason, when the left and right parallax images are obtained, the front video object 126G is large as shown in FIG. 28B, the left eye image 126GA and the right eye image 126GB appear to be separated, and the parallax amount 126I also increases. On the other hand, the distant image object 126H is small, the left-eye image 126HA and the right-eye image 126HB appear to be separated, and the parallax amount 126J is also small.

  Therefore, if there is information on the parallax amount (126I or 126J) or the parallax angle information (126D or 126E), the right-eye video is estimated from the left-eye video (video generation by parallax information conversion) as shown in FIG. 28B (126K). And 126L). This condition is based on the premise that the brightness and color do not change depending on the viewing angle, and therefore, the information that cannot be estimated by this estimation about the wraparound of the video or the change of the shadow due to the angle.

  Here, in the stereoscopic video recording apparatus shown in FIG. 29, the parallax angle is extracted from the in-plane position information of the video object obtained from the motion detection block 147 of the left-eye video and the right-eye video, and the parallax information calculation circuit 191A performs macroblock unit or Calculate disparity information in units of pixels. Further, in order to perform compression in the time axis direction, the depth direction motion detection circuit 191C extracts a motion vector in the depth direction for each screen. The estimated parallax information generation circuit 191D generates the estimated parallax information using the motion information and the parallax information in the depth direction. Further, as described above, the video on the opposite side (explained here as the left-eye video) cannot be completely reproduced from only one video (explained as the right-eye video here) information only by the parallax information, but the change due to the wraparound of the image ( Etc.), etc. will remain as information that cannot be estimated.

  For this reason, in the stereoscopic video recording apparatus shown in FIG. 29, in the stereoscopic video compression, the reverse parallax calculation processing circuit 191B first uses the parallax information to convert the video on the reverse side (described here as the left-eye video) using the parallax information. Decode reproduction is performed, and a difference between this and a video obtained by compressing the actually captured video on the opposite side (video on the frame memory 153 in the local decoder) is obtained. The information obtained by this difference is the information of the portion that cannot be reproduced due to the above-described wraparound of the image, and can cover the portion that cannot be completely reproduced by the disparity information even in the compressed stream using the disparity information. Although not shown in the figure, when a motion vector in the depth direction is extracted, the amount of change in parallax is also used as information. Therefore, as with a local decoder for normal information compression, an inverse quantization circuit and a DCT inverse transformation circuit, By using the frame memory and reproducing the original video from the motion vector in the depth direction by a local decoder and recomparison, the motion efficiency in the depth direction can be used to increase the compression efficiency.

  Here, video data in units of screens is shown as shown in FIG. Right-eye main images 192A to 192G are extracted from the right-eye camera in FIG. 30, and left-eye sub-images 194A to 194G are extracted from the left-eye camera. Here, the parallax information calculation circuit 191A in FIG. 29 calculates the parallax information 193 from the right-eye main videos 192A to 192G and the left-eye sub-pictures 194A to 194G. In the depth direction motion vector calculation 191C, the depth direction motion vector calculation value 196 is extracted from the change of the parallax information 193 in units of screens, and is generated as estimated parallax information 197. The estimated parallax information 197 itself may be a macroblock unit or a pixel unit of an image.

  On the other hand, at the time of video reproduction, the right-eye main videos 192A to 192G are encoded by video compression to become compressed videos 195A to 195G of the right-eye main video. Specifically, the compressed video of the right-eye main video includes an I-picture 195A of in-plane compressed video, P-pictures 195D and 195G subjected to temporal compression using in-plane motion vectors, and B pictures 195B, 195C, 195E, 195F. The compressed video of the right-eye main video is reproduced as the main video 198A to 198G by the normal compressed video decompression circuit. Then, reproduction sub-video (left-eye video) using the respective reproduction main video (right-eye video) 198A to 198G, estimated parallax information 204 to 210 for each screen, and information obtained by inverse quantization and inverse DCT conversion of the difference information for each screen. 211 to 217 are restored. Here, the restored video portion from the difference information plays a role of complementing a portion that cannot be reproduced by the estimated parallax information such as an image wraparound.

  The video stream using the compressed video in the stereoscopic video recording apparatus shown in FIG. 29 or FIG. 27 is shown as in FIG. 31, and is unitized as GOP video information unit data. This is because the right-eye video is originally unitized in units of GOP video information, and the differential compression data of the left eye needs to be adjusted to the unitization level of the image so that the right-eye video is used. Here, in the GOP header 170 in the GOP 168 of the right-eye video, incidental information regarding the stereoscopic video as described with reference to FIG. 25 is added. However, whether the left-eye video is compression information using the estimated parallax information 197 shown in FIG. 29, the differential compression information shown in FIG. 27, or is the method that does not compress the stereoscopic video shown in FIG. As shown in FIG. 31, it is necessary to describe information 219 indicating whether the information is GOP video information or difference information in the presence / absence 85 of the 3D video format. Further, when the stream structure is viewed at the level of the transport packet, it is shown as in FIG. 32. As in FIG. 26, the end portion of the GOP video data is padded within the transport packet, and the compressed video data in the stereoscopic direction is also displayed. Even so, the end portion is padded in the transport packet. In the above description, the right-eye video is the main video and the left-eye video is the sub-video compressed in the stereoscopic direction. The main video may be a video stream in which the right video is mixed with the sub video. However, when the mixture is permitted according to the standard, it is necessary to describe the identification information which video is the main video and which is the sub video.

  It is also possible to more easily convert the left-eye and right-eye stereoscopic video into a video stream. For example, the stereoscopic video recording apparatus shown in FIG. 33 includes a synthesis circuit 220 that is an image configuration processing unit that easily converts a video stream. FIG. 34 shows the structure of the video stream in the stereoscopic video recording apparatus shown in FIG. 33, and the left-eye or right-eye video GOP 221 is one GOP video information unit. FIG. 35 shows the structure of the transport packet level hierarchy of the video stream in the stereoscopic video recording apparatus shown in FIG.

  Here, the input left-eye and right-eye parallax images are once input to the synthesis circuit 220, and are inserted as two vertically long screens in one screen as shown in FIG. At this time, the pixels of each video are not simply thinned out in the video line, but are subjected to filter processing and compressed in the horizontal direction, and then combined with the left-eye right-eye video. In this manner, each screen is composed of two vertically long left-eye videos and right-eye videos, and thereafter, a stream is generated using a normal image compression processing method. Even in this case, in the video stream shown in FIG. 34, it is described in the supplementary information 51 or the 3D information area 176 in the GOP header 170 that the video information is compressed in the horizontal direction so that it is not reproduced as it is on a normal TV. It is necessary to do. Further, even when the video stream structure shown in FIG. 34 is adopted, at the level of the transport packet, as in FIGS. 26 and 32, the padding data 184 is compared with the final data 183 of the transport packet at the end of GOP video information. Process to fill in information. In the present invention, the stereoscopic video recording apparatus and the stereoscopic video recording method recorded on the optical disc are described, but it goes without saying that the same effect can be obtained even if the recording medium is a hard disk.

(Embodiment 4)
Next, the fourth embodiment will be described below with reference to the drawings. Although the stereoscopic video recording apparatus has been described in the third embodiment, the stereoscopic video reproducing apparatus will be described in the present embodiment. FIG. 36 is a block diagram of the stereoscopic video reproduction apparatus according to the present embodiment. 36, the demodulation / correction circuit 222, the address header recognition circuit 223, the IF (interface) 224 for connecting the optical disk drive part and the back end that is the video / audio processing part, and the optical disk drive part. And a data buffer 225 for temporarily storing data. 36, a system decoder 226 for separating a stream of video / audio data, an MPEG / H264 decoder 227 for decompressing compressed video, an audio decoder 228, a caption table, and the like. OSD decoder 229 and a depth generation circuit 229A for OSD information. Further, in the stereoscopic video reproduction device shown in FIG. 36, a 3D video processing circuit 230, a blending processing circuit 229B for covering the video with OSD information, a general-purpose IF 231 to the outside, a right-eye dedicated IF 232, a left-eye dedicated IF 233, A buffer circuit 234 and a system controller 235 for the entire back end are provided.

  FIG. 37 is a block diagram showing a portion for decoding the left-eye video from the compressed video in the stereoscopic direction shown in the third embodiment. In FIG. 37, a system decoder 236 for extracting disparity information and depth motion vector information of a video stream, an MPEG and H264 decoder 237 for decoding a compressed video stream such as MPEG and H264, disparity information 238, and motion vector information 239, a parallax information calculation circuit 240, and a left-eye image reproduction circuit 241. Note that the parallax information 238, the motion vector information 239, the parallax information calculation circuit 240, and the left-eye video reproduction circuit 241 constitute a 3D video processing circuit 230.

  Here, in the stereoscopic video reproduction apparatus shown in FIG. 36, first, the audio / video data and the auxiliary data described on the optical disk 165 are reproduced by the demodulation and correction circuit 222 in the optical disk drive. At this time, the servo circuit 162 operates so as to continue to extract the reproduction signal from the optical head 164 with high quality, and the address header recognition circuit 223 functions to instantly access a predetermined address. Here, the data reproduced from the optical disk drive is once inputted to the data buffer circuit 225 via the IF circuit 224 and then inputted to the system decoder 226. The system decoder 226 separates a stream such as video / audio data, and audio information is input to the audio decoder 228, OSD information is input to the OSD decoder 229, and video information is input to the MPEG / H264 decoder 227.

  Note that the OSD information is generated as OSD information having a depth by the auxiliary information obtained from the system decoder 226 by the OSD depth setting circuit 229A. Also, the video stream decoded by the MPEG / H264 decoder 227 is processed as 3D video information by the 3D video processing circuit 230, blended with the OSD video having a depth by the blending circuit 229B, and HDMI is used when the transfer rate is low. The left-eye image can be output by the left-eye dedicated IF 233, and the right-eye image can be output by the right-eye dedicated IF 232.

  Further, when the one-side video as shown in the third embodiment is further compressed using the parallax information, the 3D video processing 230 in the stereoscopic projection playback device is configured as shown in FIG. Here, the parallax information calculation circuit 240 performs the parallax information calculation for each pixel or macroblock using the parallax information 238 and the depth motion vector 239 which are the compressed video information of the left eye extracted by the system decoder 236, and starts from the right-eye video. A conversion coefficient for generating a left-eye image is generated. Using the conversion coefficient, the left-eye video reproduction circuit 241 reproduces the left-eye video from the right-eye video generated by the MPEG / H264 decoder. Here, if the compressed left-eye video is only compressed by the parallax information, only re-conversion based on the output of the parallax information calculation circuit 240 is performed. If the compressed information has been subjected to the above, it is necessary to incorporate an inverse quantization and inverse transform circuit in the left-eye video reproduction circuit 241.

  Next, a description will be given of a stereoscopic playback device that reproduces non-stereoscopic 2D video from left-eye and right-eye stereoscopic video. FIG. 38A is a block diagram of a stereoscopic playback device that reproduces 2D video. In FIG. 38A, a synthesis processing circuit 242 based on parallax information is provided. FIG. 38B is a diagram schematically illustrating an image formed by the composition processing circuit 242, and an image obtained by combining the left-eye image 232A and the right-eye image 233A is a 2D image 231A. Here, a general display device such as a TV does not always support 3D video, but rather supports 2D video. Therefore, when playing back a medium in which only 3D video is described, it is desirable that 2D video can be played back. As the simplest method, 2D video can be reproduced by displaying only the right-eye video or the left-eye video. For example, if the TV only supports 2D video, it is automatically detected in the link connection process between the player and the TV, and only one video is always played back.

  However, in this method, in the case of an image that is close to the eyes (appears popping out), the amount of parallax is large, and an image with a significantly shifted left and right position such as a left eye image 232A and a right eye image 233A shown in FIG. There was a problem that would become. Therefore, the parallax information in the left-eye and right-eye images can be combined to reproduce a video at an intermediate position, such as the 2D video 231A, so that a 2D video without a sense of incongruity can be reproduced. However, since both sides of the screen in this case cannot be calculated if the amount of parallax is large, if the original video is a left-eye video that is wide on the left side and a right-eye video is not shot on the right side, the video 241A The image looks like the part (both sides of the screen) is cut.

  Further, as shown in the second embodiment, there is a concern that the amount of popping out of the screen is large, which may increase eye fatigue and startle feeling. Therefore, FIG. 39A shows a block diagram of a stereoscopic video reproduction apparatus in which the pop-out amount can be varied. 39A includes a left-eye video reproduction circuit 243 based on coefficient-changed parallax, a right-eye video conversion processing circuit 244 based on coefficient-variable parallax, a user interface 245 for changing the pop-out amount, and a parallax information coefficient change unit 246. ing. FIG. 39B is a diagram for explaining the variation of the pop-out amount of the stereoscopic video reproduction device. Further, FIG. 39 (c) is a diagram for explaining the result when the pop-out amount is changed by the circuit of FIG. 39 (a). FIG. 39D shows an OSD bar 246A for changing the pop-up amount displayed on the display device connected to the stereoscopic video reproduction device.

  In the method in which one-side video is compressed with parallax information as in the stereoscopic video recording apparatus shown in FIG. 29, the parallax information related to the pop-out amount is linked in units of pixels or macroblocks. Therefore, when there is an instruction to change the pop-out amount from the user, the instruction is input to the user interface 245 of FIG. 39D using, for example, an OSD screen as shown in the OSD bar 246A of the TV screen, The conversion unit determines how much the degree of popping is attenuated by the changing unit 246. The parallax calculation amount in the parallax information calculation circuit 240 is determined based on the conversion coefficient. If the left-eye video, the left-eye video reproduction circuit 243 using the coefficient-changed parallax. Thus, the parallax amount between the left-eye image and the right-eye image is converted and displayed so that the left-eye image 126GA and the right-eye image 126GB are changed from a wavy line to a solid line as shown in FIG. As a result, the stereoscopic image obtained from the outputs of the dedicated IFs 232 and 233 is reproduced with a small pop-out amount like the stereoscopically viewed triangular figure in FIG.

  Further, in the stereoscopic video playback device shown in FIG. 39A, when the parallax information is recorded on the video stream, the pop-out amount is converted using this, but there is no parallax information. Can be considered. Therefore, the stereoscopic video playback device shown in FIG. 40 shows a configuration in which the pop-out amount can be controlled even when parallax information is not recorded on the video stream. In the stereoscopic video reproduction device shown in FIG. 40, MPEG and H264 decoders 237A and 237B, a parallax information extraction unit 247, a parallax conversion unit 248 for a right-eye video, and a parallax conversion unit 249 for a left-eye video, respectively, for left-eye video and right-eye video. And. In the stereoscopic video reproduction apparatus shown in FIG. 40, the parallax information may be newly detected from the decoded video of the left-eye video and the right-eye video by the parallax video extraction unit 247. Also, this disparity information is generated by the disparity information calculation unit 240 via the user interface 245 and the disparity information coefficient changing unit 246 as in the case of FIG. 39A, and the disparity conversion of the right-eye image is performed. Are supplied to the unit 248 and the parallax conversion unit 249 of the left-eye video.

  In the present embodiment, an apparatus and a reproducing method for reproducing stereoscopic video information recorded on an optical disc have been described. Needless to say, the same effect can be obtained even if a hard disk is used as a storage medium.

(Embodiment 5)
In the fifth embodiment, when the planar video and the stereoscopic video in the above first to fourth embodiments are mixed, the video is delivered in a predetermined format, etc. Audio viewing is possible. Therefore, in the following description, detailed description regarding the planar video and the stereoscopic video is omitted, but it can be implemented in combination with the planar video and stereoscopic video embodiments in the first to fourth embodiments. .

  In Embodiments 2 to 4, stereoscopic video information is recorded on an optical disc medium, and the case of viewing this is described. However, in recent BD players, a standard for network connection has been added, and the information is recorded on the disc medium. It is possible to view 3D images by network viewing instead of using the above information.

  Therefore, FIG. 41 describes a system for performing stereoscopic viewing via a network. In FIG. 41, a plurality of video distribution source server groups 250, 251, 252, and 253 that can be selected by the user, and intermediate AV devices at home. A transcoding server 254 that transcodes and relays video information from each video distribution source server, a player or recorder 255 capable of reproducing stereoscopic video, a TV 256 capable of stereoscopic viewing, and stereoscopic viewing Glasses 257, stereoscopic video signals 258, 259, 260, 261 transmitted from the video distribution source server, right-eye video R, left-eye video L, stereoscopic video information 262 distributed from the transcoding server, A left-eye video 263 obtained by performing differential compression of the video is shown. The stereoscopic video information is a stereoscopic video distribution content that enables stereoscopic video viewing by using a planar video composed of only one of the left-eye video or the right-eye video and information on the video on the opposite side of the planar video. is there.

  FIG. 42 shows a viewing selection screen during network viewing. In FIG. 42, a title name 264, contents 265, and identification information 266 indicating 3D or 2D are shown.

  FIG. 43 shows a method of downloading three-dimensional widget information from the network and displaying it on the TV screen. In FIG. 43, the signal format 267 of the OSD data downloaded from the transcoding server 254 and the position in the depth or pop-out direction are shown. A format 268 in which information is added to the in-plane OSD information, a format 269 in which the OSD itself is stereoscopic video information for the right eye and the left eye, and a widget 270 that is stereoscopically displayed on the TV screen are shown. When downloading widget information, a widget information distribution request is output to the transcoding server 254, and the stereoscopically viewable widget information 270 in the transcoding server 254 is stereoscopically displayed to a player or the like capable of stereoscopic viewing. It is distributed as a format 267.

  Since it is configured in this manner, the widget distribution from the server can also be delivered in a three-dimensional widget according to the viewing environment of the TV, so that effective viewing can be performed according to the situation of the stereoscopic video content.

  Next, an embodiment of the present invention will be described with reference to the drawings. Content viewing such as “You-Tube”, which is already common in the PC domain, is built on the premise that the CPU has a high computing speed. Therefore, even if each content provider uses a different video distribution format, it can be handled by downloading and installing a decoding program required by each user from the network. However, in general AV equipment, the performance of the installed CPU is low, and the user does not bother to download the SW necessary for decoding, so a dedicated decoder or decoding processing program is installed, and this decoding processing Only services that can handle this are connected. Therefore, it is necessary to deal with different decoding processes and user IFs.

  Therefore, in the stereoscopic video viewing system of FIG. 41, the stereoscopic playback player or the stereoscopic video recorder 255 first confirms whether the TV that the user views (externally) is a stereoscopic video compatible device via the HDMI cable, and then When the TV is a 3D image compatible device (3D viewing is possible), the 3D playback player or 3D video recorder 255 instructs the transcoding server 254 to send a content menu including 3D video. Here, even if each video distribution source server 250-253 is distributed in a different video distribution format (when the format is different, such as stereoscopic video information 258-261 shown in FIG. 41), the transcoding server 254 The video signal format is a video signal format that can be decoded by a player or a TV that can be viewed three-dimensionally by performing format conversion (format conversion as shown by the stereoscopic video information 262) once by the format conversion means, for example, Embodiment 2 to Embodiment 3. Re-distributed as 3D video information in the same format as that recorded on optical media, as described in, and viewed using a decoder circuit or decoding program for media playback originally owned by an inexpensive player or recorder Can Kill.

  Furthermore, in the present embodiment, for example, the 2D video described in FIGS. 31 to 32 of the third embodiment with reference to either the right-eye video or the left-eye video is used as a reference, and the video on the opposite side of the 2D video is used. A signal method is used in which compression is further performed by taking a difference from the video on the 2D video side. This method is the stereoscopic video signal format (compression method) for recording on the storage medium described in the third embodiment. However, the video content from any video distribution source server in this transcoding server 254 in FIG. By converting (transcoding) and distributing in accordance with a 3D video signal format for recording media such as an optical disc, the player or the recorder 255 can perform 3D playback viewing. 3D video can be decoded.

  Here, from the video distribution source server of FIG. 41, a certain server 2CH camera video of the stereo camera is respectively MPEG2 or H.264. H.264 compression format transmission is also assumed. In this case, the transcoding server 254 further compresses the video information of one side CH by taking the difference between the left and right videos described in the third embodiment of the present invention. To be transmitted to the player or the recorder 255. In this case, since the video information of the method in which the video information of the CH on one side is further compressed by taking the difference between the left and right images to be transmitted is the same method as the video format recorded on the optical disk, for example, the same decoder circuit or Playback processing can be performed by the decode SW.

  The reason why such differences in video format are not usually considered is that storage media need to be in a limited medium capacity range, so it is necessary to select a method with high compression efficiency. This is because, for example, the right and left video can be delivered as they are in the normal image compression method because it is not always necessary to consider capacity restrictions in the exchange of information with the server. However, with the diversification of video distribution formats, the burden on the decoder side also increases. By using the transcoding technology as in this embodiment, the format is unified or reduced, so that a decoder having an inexpensive CPU can be obtained. Viewing on an on-board TV or player becomes possible.

  Also, not only video and audio formats but also OSD information and subtitle information can be redistributed as the same format as the media recording format, so that it is possible to operate with the same user IF as the disc media playback. .

  If the 3D player or 3D recorder 255 of FIG. 41 is a recorder rather than a playback-only machine, it is possible to directly download and record the 3D video in the recorder 255 without converting it to a media recording format (FIG. 41). 43). However, as a matter of course, even when downloading to this recorder or viewing directly on a player or TV, the network distribution video signal is encrypted for network content protection regardless of 2D video or 3D video. Needless to say, key exchange and authentication work for encryption are required between servers. In the case of download recording, there is an advantage that it is not easily affected by the network environment, so even if the video signal is interrupted due to the network environment, video and audio can be played smoothly without interruption during playback. It is possible. In addition, because of such advantageous conditions, in the case of download recording, it is possible to set the distribution bit rate higher than in the case of just watching.

  Further, as described in the second embodiment, when the stereoscopic video is composed of a plurality of angle videos, the video data at the time of viewing becomes enormous. When such a multi-angle stereoscopic video is put in a storage medium, it is not possible to put in too many angles due to the capacity limitation of the storage medium. However, if it is stored on the server, it is possible to put a lot of angle information with almost no restrictions. For example, when an angle switching operation is performed by a multi-angle switching means such as a TV remote controller, a player or a recorder It is also possible to transfer the angle switching command information to the transcoding server, switch the video data angle on the server, convert the format, and redistribute it to the player or recorder. Of course, when format conversion is necessary at the transcoding server, the video distribution source server first redistributes the video with different angles, and the redistributed stereoscopic video is converted into the format at the transcoding server and then distributed to the player or recorder. It will be.

  Since it is configured in this manner, even a stereoscopic image having a large amount of information having a plurality of angle information can be stored and viewed on a server without being limited by the capacity of an optical disk medium or the like. In addition, in response to an angle switching request from the user (external), it is now possible to switch and distribute the angle of stereoscopic video content stored in the server.

  Note that in the stereoscopic view capable player or the stereoscopic view capable TV, the communication time between the transcoding server and the video distribution server, the switching time to the video having a different angle in the video distribution server, the format conversion processing time in the transcoding server, and the trans It is desirable to have a video distribution buffer having a capacity sufficient to exceed the total communication time between the coding server and the stereoscopic viewing player or the stereoscopic viewing TV.

  Further, by sequentially moving the multi-angle by the angle sequential switching means (clockwise, counterclockwise), it becomes possible to view the object while rotating or wrapping around, as in the second embodiment. At this time, generally, there is a time delay between the player or recorder and the server, and a time delay between the server under video distribution and the transcoding server, so that the continuous switching of the angle may be a jerky movement. In such a case, an angle image having a plurality of rotation angles such as “rotate” or “shift continuously in a specific angle direction in a specific angle unit” in advance with a single command. By defining continuous commands to be moved as commands that can be operated at once, and sending them to the transcoding server or video distribution source server, it becomes possible to realize continuous change of angles on the video distribution system of the server, Smooth movements can be reproduced.

  It is also assumed that the recorder or player 255 of FIG. 41 does not exist and is directly connected to the TV via a network. In this case, the decoder circuit or decoder SW included in the player 255 may be mounted on the TV 256 in FIG. However, in this case, it is necessary to perform the decoding process on the LSI in the TV. Depending on the processing speed of the LSI, it is assumed that the process may not be in time. In this case, the player or recorder is externally attached, After the decoding process is performed, viewing is performed.

  In the net viewing screen of FIG. 42, the device authentication between the transcoding server and the player / recorder is completed, and that a TV capable of stereoscopic viewing is connected to the player / recorder, such as flag information of the HDMI cable, etc. After the player or recorder recognizes it by the confirmation means (the viewing environment confirmation information is retained by the retaining means), the viewing environment confirmation information indicating that the player or recorder is a 3D viewing environment is sent to the transcoding server. In a video distribution menu composed of planar video that is transmitted (transmitted) by a transmission means and prepared in advance in a transcoding server, a planar video viewing selection menu is provided in a 3D viewing-enabled environment for stereoscopic viewing only for planar viewing. If the 3D content and 2D content are mixed Transferred to the player or recorder as a list which identify the image or stereoscopic video, the remote control at for example the selected portion of the TV to select a content to be viewed by pressing the menu is highlighted. As a result, a content menu screen suitable for the viewing environment is distributed, and the user can select the content he / she wants to view.

  At this time, when 3D content is selected, it is also necessary to display content that the user must deal with in viewing such as “please wear glasses” on the TV screen.

(Embodiment 6)
Next, a case where 2D video is converted to 3D in the transcoding server when stereoscopic video is not distributed in advance will be described with reference to FIG.

This system generates stereoscopic video information in the 3D format generation unit 282 from the planar video information acquired by the system decoders 273 and 274, and is requested according to the viewing environment of the television 285 via the transcoding server 283. The video information corresponding to the content of the video is provided.

  FIG. 45 shows a system for distributing information of an external stereoscopic movie or a stereoscopic video recorder storing videos taken with the stereoscopic movie to a transcoding server for later viewing. 3 further shows a three-dimensional movie 286, a three-dimensional recorder 287, and a system decoder C288 for separating a signal from the three-dimensional movie or the three-dimensional recorder into video, audio and incidental information. In addition to the system decoders 273 and 274, the above 3D format including the video information from the system decoder 288 is generated.

  46 and 47 show the operation flow of FIG. FIG. 48 is a flow describing a system for viewing a personal video such as a movie or movie from a recorder that has recorded a personal video to a server and performing a conversion service from 2D to 3D.

  The operation will be described with reference to FIGS. 44, 46 and 47. FIG.

  First, the user switches the playback screen of the stereoscopic BD player 284 while operating the TV 285 with a remote controller or the like, and selects a VOD viewing service menu such as a movie to be viewed (STEP 101). Next, the three-dimensional player 284 performs device authentication with the transcoding server 283 (STEP 102).

  After the device authentication, the three-dimensional player 284 confirms information related to the viewing environment by communication through the HDMI cable (STEP 103). It is confirmed whether the TV 285 is compatible with 3D (STEP 104). If the viewing environment is a 2D environment, the stereoscopic player 284 requests a 2D menu from the transcoding server 283 (STEP 105), and the viewing environment is a 3D environment. In this case, the stereoscopic player 284 requests the transcoding server 283 for a 3D menu in which 2D and 3D are mixed (STEP 106).

  The transcoding server 283 distributes the 2D menu to the stereoscopic player 284 if there is a 2D menu request from the stereoscopic player 284 (STEP 107), and if there is a 3D menu request, the 2D and 3D to the stereoscopic player 284. A 3D menu in which is mixed is distributed (STEP 108).

  Next, the viewing content is selected from the menu distributed by the user (STEP 109, STEP 110). It is confirmed whether the selected content is 2D content or 3D content (STEP 111). If 2D content is selected, the stereoscopic player 284 first performs a charging process with the transcoding server 283 (STEP 112), and then The transcoding server 283 selects a content owning server that owns the selected content (STEP 113).

  Then, server authentication is performed between the content-owning server and the transcoding server 283 (STEP 114). After authentication, a content transmission request is made (STEP 115), and charging authentication between servers (second charging process) is performed (STEP 116). Through the billing authentication between the servers, a part of the amount paid by the user becomes a cost on the transcoding server side, and the rest is returned (distributed) to the content provider.

  Next, desired content is transmitted from the content providing server to the transcoding server 283 (STEP 117), and the transcoding server 283 performs format conversion processing so that it can be played back by the stereoscopic player 284 (STEP 118). The stream is transmitted to the stereoscopic player 284 (STEP 119), and 2D playback processing is performed by the stereoscopic player 284 (STEP 120).

  On the other hand, when the user selects 3D content, the stereoscopic player 284 first performs a charging process with the transcoding server 283 (STEP 121), and then the transcoding server 283 has the desired content as in the case of 2D content. A content-owning server is selected (STEP 122). Then, an inter-server authentication process is performed (STEP 123), a content transmission request is issued (STEP 124), and an inter-server accounting process is performed (STEP 125).

  Next, the content is transmitted from the content owning server to the transcoding server 283 (STEP 126), and it is confirmed whether the transmitted content is 2D video or 3D video (STEP 127). The format is converted into a format that can be played back by the stereoscopic player 284 (STEP 128), the converted stream is transmitted to the stereoscopic player 284 (STEP 129), and 3D playback processing is performed by the stereoscopic player 284 (STEP 130).

  In this format conversion, as described in the fifth embodiment, for example, one of the left and right images is compressed by the difference between the left and right images, and distributed as the same signal format as the 3D content recorded on the media. Is done.

  Even when 3D content is selected, if the content possessing server has only 2D content, the transcoding server 283 performs conversion from 2D to 3D by the conversion means (STEP 131). Then, the transcoding server 283 performs format conversion into a format that can be played back by the stereoscopic player 284 (STEP 132), the converted stream is transmitted to the stereoscopic player 284 (STEP 133), and 3D playback processing is performed by the stereoscopic player 284 (step 133). (STEP 130).

  Here, the distributed stream is divided into a video signal, audio, widget information, and the like by the system decoder 273 or the system decoder 274. Next, the background part, the person part on the near side, the object, the house, or the object part in the foreground are extracted from the video signal by the background part extracting means and the foreground video separating means, and these are extracted by the stereoscopic position weighting means before and after the stereoscopic direction The relationship and the pop-up depth amount are defined and arranged as stereoscopic video information.

  In particular, the front-rear relationship in the three-dimensional direction and the pop-up depth amount are estimated to be farther away as the size of an object or person due to the presence of a large one in front, the front-rear relationship by analyzing the motion of the image of the overlapping part, The solid direction is positioned by analyzing the fineness of the background. Next, these three-dimensional video parts are once combined as a video signal and then formatted together with audio and widget information. The formatted video signal is distributed to the stereoscopic player in the same format as when the 3D signal is originally stored in the content server, and the stereoscopic video is reproduced.

  In addition, the above describes that only the video signal is stereoscopically converted and distributed. However, it is also possible to convert the sound image localization into a stereoscopic sound signal and to convert the widget display information into a three-dimensionally converted display. Is possible.

  For general widget information, weather forecast marks, baseball broadcast bulletins, news, stock prices, etc. are displayed as a small overlay on the TV screen, or the screen is divided and displayed in an area other than the content information screen. Has been done. In this case, the widget information distribution request is output to the transcoding server, the one having the desired widget information is selected from a plurality of video distribution servers, and the stereoscopic viewing content and the widget information are displayed so as to be displayed in an overlay or divided. The combined second stereoscopic viewing content is generated and redistributed.

  In the case of displaying widget information in the case of viewing stereoscopic video, since it is Point whether to display the widget information in the stereoscopic direction position, it is desirable to be able to change the position in the stereoscopic direction. For this reason, there is a method in which the two-dimensional widget information is transmitted from the transcoding server as three-dimensional OSD information by adding the position in the three-dimensional direction as in the embodiment of the present invention. Widgets can be distributed from the server according to the viewing environment of the TV, and the position of the stereoscopic direction in the widget information of the stereoscopic video can be changed. It is possible to select a specific widget position, or to change the widget arrangement from the display panel where the eyes are less tired to the depth side.

  In this case, the 2D image information has an offset in the depth or the protruding direction, or is transmitted as stereoscopic information of the left and right images (which is used as a reference and the rest is differentially compressed) in the same way as the 3D image. It can be transmitted as a signal format that can be decoded by a player or TV. Also, there is a method in which the stereoscopic video content is overlaid in advance on the transcoding server and the stereoscopic video information after the overlay is transmitted. In this case, the player or TV does not require a special decoder for displaying the widget, so the CPU load for displaying the widget can be reduced. However, all the layout changes on the screen are displayed on the transcoding server. It is necessary to send a change instruction, which causes a time delay for access.

  In addition, as described above, once the widget information is received by the transcoding server, a widget information distribution request is output to the transcoding server, and a widget service distribution source widget that is a plurality of video distribution servers can be selected or used simultaneously. In addition, it is also possible to convert a 2D video widget into an OSD signal format capable of stereoscopic display.

  In addition to video distribution from the content owning server, data is generally transferred to the transcoding server from a home recorder that records 2D video captured with a movie or video recorded with a movie. It is also possible to perform a conversion process from 2D to 3D and view the content on a stereoscopic player. In this case, the plane-to-stereoscopic conversion function in the transcoding server can be used to enjoy a stereoscopic image, and the degree of the stereoscopic can be set by the user using the stereoscopic direction position variable input means for varying the stereoscopic degree. By enabling the transmission of the three-dimensional position variable control command, it is possible to increase the sense of presence by enhancing the three-dimensional effect, or to suppress the pop-out amount within a range that is easy on the eyes by reducing the three-dimensional effect. Became.

  Here, the stereoscopic conversion from a flat image is an image processing unit that extracts a background component of an image and a person or an object in the front, and extracts individual image portions, which are weighted in a stereoscopic direction by a stereoscopic direction weighting unit. However, it is obtained by image synthesis. Since the weight of the stereo direction in this stereo transformation can be changed, the depth and the amount of popping out can be adjusted to match the viewer's health, screen size, and realistic sensation. It was. Note that the three-dimensional position change, the three-dimensional weighting, and the combination thereof are the same for not only the widget information but also three-dimensional information that is converted and combined from a plane image.

  In addition, it is possible to determine which image piece is in front by identifying the overlapping state of each extracted image part as the image moves, and to specify the position in the stereoscopic direction. The 3D image synthesized in this way is converted into a video format that can be played back by a player or TV by the 3D formatting unit and distributed. In addition, if a method for assigning a stereoscopic direction position by image segment extraction is used, even if the original image is a stereoscopic image, it is possible to change the degree of stereoscopic effect by separating it into image segments and changing the weights again. It is. In particular, when the original is a stereoscopic image, each pixel has a parallax, and the stereoscopic direction position of each pixel is specified. Therefore, changing these stereoscopic direction positions is the method described in the fourth embodiment, etc. Can be easily realized.

  Also, at this time, device authentication is performed between the movie / recorder and the transcoding server, and the user ID number obtained by registering in advance as a member is transmitted at the time of device authentication, so that the stereoscopic conversion service can be received. Is also possible. As for the billing process, it is possible to pay a fixed amount of data or a three-dimensional service up to a certain time limit at the time of member registration, but it is also possible to perform a payment process every time data is uploaded to the server .

  These uploaded 2D videos of individuals are managed by the ID number registered by the uploaded user, and at the time of viewing, it is confirmed by device authentication that the same ID number is received from the 3D player (ID is re-input). It can be played back. At this time, even during stereoscopic viewing, by inputting the user ID in the stereoscopic player, the personal ID is protected by authenticating the user ID and the device ID, and only the video uploaded by the user is viewed. Furthermore, by adding a disclosure code to each uploaded user's personal video, it is possible to send the disclosure code to other people such as acquaintances and family friends by e-mail etc. for viewing. Become. It is also possible to automatically confirm the registered ID together with the device authentication by presetting the ID registered at the time of uploading to a player or TV capable of stereoscopic viewing.

  Next, the data is uploaded to the transcoding server 283 from the home recorder device 287 which has recorded the 2D video imaged by the movie 286 or the like or the video imaged by the movie 286, and the conversion processing from 2D to 3D is performed here. The flow from when the conversion is performed in the conversion means until viewing with the stereoscopic player will be described with reference to the flowchart of FIG.

  First, the user gives an instruction to upload video captured by a movie or the like to a transcoding server directly or via a terminal that can be connected to a network such as a recorder (STEP 201). The movie or the recorder device performs device authentication with the transcoding server in response to an upload instruction from the user (STEP 202). After device authentication, the movie or recorder device transmits the encrypted user ID to the transcoding server (STEP 203), and performs accounting processing with the transcoding server (STEP 204). When the charging process is completed, video uploading is started (STEP 205). The uploaded video is converted into a stereoscopic video using the plane-to-stereo conversion function of the transcoding server.

  Next, the flow from when the user downloads the video from the transcoding server to viewing it will be described with reference to FIGS.

  First, the user selects personal video distribution from the menu screen 289 of the stereoscopic player (STEP 206). When the user selects personal video distribution, the three-dimensional player performs device authentication with the transcoding server (STEP 207). After the device authentication, the stereoscopic player displays a user ID input screen 290, and the user inputs the user ID (STEP 208). When the user ID is input, the stereoscopic player transmits the encrypted user ID to the transcoding server. The transcoding server confirms the device ID and user ID of the stereoscopic player, and when the device ID and user ID match the device ID and user ID held by the corresponding content on the server, the information of the corresponding content is transmitted to the stereoscopic player. (STEP 209). The stereoscopic player displays the received content information on the personal content selection screen 291 (STEP 210). Here, if necessary, billing processing is performed between the stereoscopic player and the transcoding server (STEP 211).

  The user selects desired content from the personal content selection screen 291 (STEP 212), and the stereoscopic player requests the transcoding server to transmit the selected content (STEP 213). Here, billing processing may be performed on the content selected by the user. The transcoding server performs plane-to-stereo conversion on the selected content, and converts the selected content into a stereoscopic video (STEP 214). Conversion to a stereoscopic image may be performed in advance. The transcoding server converts the selected content into a stereoscopic video and distributes it to the stereoscopic player (STEP 215). The stereoscopic player reproduces the stereoscopic video distributed from the transcoding server, so that the video captured by the user can be enjoyed as a stereoscopic video (STEP 216).

  In addition, as described above, the method of converting to 3D video and distributing it has been described. However, the player to be played back may be for normal 2D playback. In this case, the file storage of the server is not performed without performing the 3D conversion service. In addition to receiving the function as a service, the server only has conversion processing into a format that can be reproduced by the player by transcoding processing. In particular, even when 3D conversion is not performed, the storage service can be used sufficiently. In this case, even 3D video-only distribution content can be viewed on a normal 2D playback player in the same manner by converting it into a 2D video format using this transcoding server and redistributing it.

  In addition, as described above, an ID is attached to a personal video, and an individual uploaded to the server only sees an image having a copyright of himself or a recorded image. Copyright issues arise when uploading to other people and allowing others to view. In this case, for personal contents such as movies, only those having an encryption key embedded in the video by embedding the encryption key in the video on the personal video side by applying image watermarking technology in the movie, etc. It is also possible to include a mechanism for permitting delivery to others via this transcoding server.

  Note that it is also possible to implement a stereoscopic video viewing system in which stereoscopic video can be viewed using the stereoscopic video distribution content distributed by the stereoscopic video distribution system described in the fifth and sixth embodiments.

  In addition, it is possible to implement a stereoscopic video viewing method in which a stereoscopic video can be viewed using the stereoscopic video distribution content distributed by the stereoscopic video distribution method described in the fifth and sixth embodiments.

  In addition, it is possible to implement a stereoscopic video viewing apparatus that allows a stereoscopic video to be viewed using the stereoscopic video distribution content distributed by the stereoscopic video distribution apparatus described in the fifth and sixth embodiments.
