DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of recording television broadcast video, and automatically selects a preselected video from a video of a television program broadcasted as a moving picture by a viewer side device. It is related to a system that records and uses the information.

[0002]

2. Description of the Related Art Television receivers have become widespread in ordinary households,
Television broadcasting is currently the largest communication media.
Television broadcasts a wide range of programs, including news, sports, and dramas. These videos contain a lot of useful information for life. For example, videos of recipes of cooking programs are recorded and used by various means. As a means for recording the contents of a television broadcast, there is a method of recording on a video tape using a video tape recorder. When the TV program content you want to record is broadcast, press the record button on the videotape to record,
A method of stopping recording by pressing a stop button is employed. Further, as another means, there are a television receiver on which a frame memory is mounted and a dedicated still image recording device. When a video to be recorded is displayed on the television screen, when a recording button such as an infrared remote control is pressed, a video signal is recorded in the frame memory.

[0003]

Conventionally, when a useful video is included in a part of a broadcast video of a television program, recording is performed using a video tape recorder, a television receiver with a frame memory, or a still image recording device. However, it is necessary for these devices to instruct recording by manual operation using a remote controller or the like. Most of the broadcast images of television programs are images that do not need to be recorded, but useful images may be displayed on the television screen during the program. When recording a useful image suddenly appearing on a television screen, there may be no remote control for operation at hand. Then, while searching for the remote control, the image on the television screen changes, and a case occurs where the desired image cannot be recorded. Even if a viewer desires a video in a subsequent television program, the user cannot find and record the video unless he / she keeps watching the television program. In order to solve such a problem, means for automatically recording a video desired by a viewer is required, but such a system is not currently provided. as a result,
Viewers cannot make full use of the images of television programs.

[0004] Still picture broadcasting is an example of recording and using a video picture as a still picture. Since a still image broadcast transmits a different image for each frame, a video image needs to be identified for each frame. Therefore, identification information for each frame is added to the video image transmitted from the still image transmission device, and the still image reception device inspects the identification information of the video image to be received for each frame, selects a still image, and converts it to a frame. Record and use in memory. Video images of a television program broadcasted as a moving image from a television broadcasting station have a large amount and various contents, and thus it is not easy to add identification information for each frame to the video image. Although a time code is used to recognize a video image of a television program for each frame, a time code, which is information on a time axis, cannot be used as identification information for selecting a video image desired by a viewer.

[0005] The video of a television program broadcast from a broadcasting station generally includes a video that is not desired by the viewer and cannot be recorded by the viewer, and a video that is generally desired by the viewer and is not recorded by the viewer. There is a target video. In general, the content of the video desired by the viewer is predetermined to a certain extent. and so on. In addition, in television broadcasting, there are times when it is desired to send a screen of a plurality of detailed recipes, such as when explaining in detail how to make a dish, but it takes a long time to display these images on a television screen for a certain period of time. May not be sent. However, these detailed recipe screens can also be used if they are transmitted in a short time and automatically recorded on the viewer-side device. Also, there are cases where the viewer cannot use the video of the television program alone even if the video is recorded. For example, a television broadcast shopping program is used as a means of shopping, but processing such as automatic ordering is difficult using only a video of a product catalog. It would be convenient if information related to the video to be recorded, such as the telephone number of the order destination of the catalog product, could be used in the form of a digital signal.

The present invention focuses on this point and aims to solve the following problems. Among video images of a television program broadcasted from a television broadcasting station, a video that is automatically recorded by the viewer is selected as a desired video from among videos desired by the viewer, and a plurality of videos are selected according to the content. And assign a category code to each category. Further, information necessary for the viewer to record and use the desired video is set as additional information for each category of the desired video. Then, the viewer automatically records the desired video using the division code of the desired video, acquires additional information necessary for using the desired video, and effectively uses the desired video.

[0007]

A television broadcasting system comprises a broadcasting station-side device 1 for broadcasting a television program, a viewer-side device 2 for receiving a television broadcast, and the broadcasting station-side device and the viewer-side device. It comprises a television signal transmission line 3 to be connected. The television broadcasting station transmits a video image (hereinafter, referred to as a desired image) automatically recorded by the viewer-side device as a part of a series of video images for viewing a television program broadcast as a moving image. Then, prior to the transmission of the desired video, the television broadcasting station transmits a video image (hereinafter, referred to as a notification video) notifying that the desired video is to be transmitted, as a part of a series of video images of the television program. The components of the notification image include a segment code of the desired image and additional information for use. In addition, the television broadcast station intermittently transmits the video of the section information of the video to be recorded. That is, the television broadcast station intermittently transmits available list information of desired video segmentation codes as an analog signal or a digital signal in a television broadcast signal such as a moving image broadcast, a still image broadcast, or a data broadcast. The above is the first
This will be described in detail below with reference to the drawings.

FIG. 1 shows a broadcast station side device 1 and a viewer side device 2.
And a television broadcasting system comprising a television signal transmission line 3 connecting the broadcasting station side device 1 and the viewer side device 2, and a series of video images 4 transmitted from the broadcasting station side device 1. Is composed of video images A, B, C, D, and E intended for viewing and notification images F and G not intended for viewing. Video images B and D are desired images. The notification image F is a video image notifying the transmission of the desired image B, and the notification image G is a video image notifying the transmission of the desired image D. The notification images F and G are formed as video signals detected by the viewer device, and each notification image is formed as one or a plurality of images. Since the notification video has a plurality of information such as a classification code of the desired video and additional information for use,
These pieces of information are formed as a plurality of partial images in the notification image.

[0009] A method of forming a notice image from an NTSC video image will be described. The NTSC video signal is 52
The frame signal of one screen is composed of five horizontal scanning line signals. The video signal of this one frame is a video signal of an odd field and a video signal of an even field are displayed alternately, and the horizontal and vertical fields of the odd field and the even field are displayed. The scanning line signals are alternately arranged on the television screen. When the notification image is formed by the NTSC system video image, the notification image is superimposed on the horizontal scanning line signal. Therefore, the notification image is formed as a horizontal image. As horizontal scanning line signals for forming a notice image, 240 horizontal scanning line signals from 23rd to 262th in the odd field and 2 horizontal scanning line signals in the even field are used.
240 horizontal scanning line signals from No. 86 to No. 525 can be used, and these horizontal scanning line signals can be used alone or by dividing continuous horizontal scanning line signals into a plurality of groups.

Although the horizontal scanning line signals of the odd field and the even field can be divided into an arbitrary number of groups, FIG. 2 shows a case where eight continuous lines are taken as one group, and the odd field and the even field are divided into 30 groups each having the same format. And a partial video is formed in this group, and the entire video frame is formed as a notification video. The partial image H is formed by a first group of odd fields and a first group of even fields. The first group of the odd field is composed of the 23rd to 30th horizontal scanning line signals, and the first group of the even field is composed of the 286th to 293th horizontal scanning line signals. The partial image H is a specific number of pulse signals, for example, 10
In the case of an image in which pulse signals are generated, a partial image H can be formed by arranging ten regions of the first group horizontally with ten white rectangles on a black background. The notification image formed as a white and black image pattern is transmitted as a high level and a low level as black as a video image signal, so that white is set to 1 and black is set to 0 and detected in the form of a pulse signal. it can. Similarly, the partial image I
Also, a partial image J can be formed, and the entire frame becomes a notification image. As the contents of the notification video, for example, the partial video H is a video signal indicating that it is a notification video, the partial video I is a video signal indicating a classification code of a desired video, and the partial video J is an addition required for using the desired video. It is a video signal of information.

Next, of the methods of forming a notice image from a digital broadcast video image, a method of setting the image formation unit as a coding unit of the data compression process will be described. MPEG-
Discrete cosine transform (DCT) coding is used in coding of 1 and MPEG-2 video signals, and the coding unit is a block of 8 × 8 pixels and a macro block of 16 × 16 pixels composed of four blocks. When the notification image is formed as an MPEG-1 or MPEG-2 image, the notification image can be formed as a clear image if a block or a macroblock, which is a unit of the compression processing of the image signal, is used as the image formation unit.

In the MPEG-2 main level format, 44 macroblocks are arranged side by side as a slice, and a picture of one screen is composed of 30 slices. When the notification video is formed in the MPEG-2 main level format, the slice included in the
It is formed by assigning white and black video to four macro blocks. A method of forming a notification image will be described with reference to FIG. A video frame composed of 480 horizontal scanning line signals is divided into three consecutive 16 horizontal scanning lines as a unit.
Divide into 0 partial frames. A partial frame composed of 16 consecutive horizontal scanning lines corresponds to a slice,
A macro block is obtained by equally dividing the video portion of the horizontal scanning line signal into 44 portions of this partial frame. That is, as shown in the video frame of FIG.
When a video frame composed of 480 horizontal scanning line signals is divided into squares of 30 rows and 44 columns, each square corresponds to a macroblock, and a row composed of 44 squares corresponds to a slice. Then, by forming a white or black image in each cell, the notification image in FIG. 3 can be formed.

As the contents of the notice image, for example, a partial image h formed by using the cells in the first row is a video signal indicating that the partial image is a notice image, and a portion formed by using the cells in the second line The video i is a video signal indicating a classification code of a desired video,
The partial video j formed using the cells in the third row is a video signal of additional information necessary for using the desired video. The notification image formed as the image of the white and black luminance signals is transmitted after being converted into an MPEG-2 image data format in units of macroblocks. Notice video is MPEG-
In the case of forming an image in units of 1 or MPEG-2 block or macroblock, data of the block or macroblock can be directly generated as numerical data. Digital video images are classified into an interlace system and a progressive system. In the interlace system, a unit of one image is a frame image composed of a video image of an odd field and a video image of an even field. In the progressive system, the unit of one image is a video image of a field.

Next, a description will be given of a method of arranging the notification video when the video images of the digital broadcast are arranged in the display order. Reference numeral 7 in FIG. 4 shows a configuration of a video image of digital broadcasting of the MPEG-1 system. MPEG-1 video images are transmitted in the form of I-pictures and P-pictures, but I-pictures have all the video signals forming one screen of video. A video image is formed from the included difference information. MPEG-
In one-system digital broadcasting, the notification video 8 is arranged before the I picture of the desired video. Since the I picture alone has all the signals of the video image of one screen, the desired image can be recorded without being affected by the immediately preceding notification image 8.

FIG. 4 shows the structure of a video image of a digital broadcast of the MPEG-2 system, and the video image of MPEG-2 is transmitted in the form of an I picture, a P picture, or a B picture. It is an I picture that has all the video signals that form one screen of video, a P picture forms a video video from the previous video information and the difference information included in the P picture, and a B picture is A video image is formed from the difference information included in the picture. MP
In the digital broadcasting of the EG-2 system, the notification image 10 is arranged before the I picture of the desired image. Since the I picture alone has all the signals of the video image of one screen, the desired image can be recorded without being affected by the immediately preceding notification image 10. Also, if the I-picture or the P-picture precedes the announcement video, those videos are not affected by the announcement video.

The notification image can be formed as a part of an image of another video image in a picture-in-picture format, and can be arranged at any position as long as it can be recognized by the viewer-side device. FIG. 5 shows a method of forming an annunciation image using a portion above a video image 11 of a television program intended for viewing. MPEG-4 of digital broadcasting
When a part of a video image can be formed by encoding in units of objects by a method or the like, there is a method in which a notification image is formed as an object and configured as a partial image of a frame image serving as a background image. For example, by giving a specific object code to a character image object "desired image: cooking recipe", it can be formed as a notice image.

[0017] The television broadcast station intermittently transmits the list information of the division codes of the desired video as television division signals as the division information of the video to be recorded. The list information of the section codes of the desired image can be formed of video data as digital data for inputting the section codes or a menu screen for selecting the section codes. FIG.
A method for forming the list information of the section codes of the desired video as the video of the menu screen will be described. In the menu screen of FIG. 6, six selection items are arranged at predetermined positions, and each selection item is numbered in order from the top. The division code of the desired image can be made to correspond to the number of the selection item on the menu screen or the display position of the selection item. The first selection item can be related as the division code 1, the second selection item can be related as the division code 2, and the third selection item can be related as the division code 3.
By specifying a selection item on the menu screen, it is possible to set a classification code. In this method, the relationship between the selection item on the menu screen and the division code of the desired video is fixed.

FIG. 7 illustrates a method of arranging a menu screen in a series of video images. The video image 12 includes video images N, O, P, Q, and R for viewing and video images M, S, and T not for viewing. The video images O and Q are desired images, the video image S is a notification image of the desired image O, and the video image T is a notification image of the desired image Q. The video image M is a video image formed as a menu screen, which is a list information of a section code of a desired image. The video image M of the menu screen is intermittently arranged in a series of video images 12 transmitted from the broadcast station side device.

As means for making the relationship between the selection items on the menu screen and the section codes of the desired video variable, the television broadcasting station uses information (hereinafter referred to as link information) for associating the selection items on the menu screen with the section codes of the desired video. Is intermittently transmitted as a television broadcast signal such as a moving picture broadcast, a still picture broadcast, or a data broadcast as an analog signal or a digital signal in association with a menu screen. FIG. 8 shows link information that associates a display position of a selection item on a menu screen with a division code of a desired image as a video image, and can be formed in the same manner as a notification image. FIG. 8 shows link information formed by NTSC video images. A plurality of continuous horizontal scanning line signals are grouped to form link information in group units. The video of the first group from the top is a video signal that specifies the partition code of the first menu item, and the video of the second group is a video signal that specifies the partition code of the second menu item. In this way, a section code can be specified for all menu items. With this link information, an arbitrary classification code can be associated with a selection item displayed at an arbitrary position. For example, a division code of 15 is selected for the selection item of the first position, and a classification code of 15 is selected for the selection item of the second position. Can associate 7 in code

Referring to FIG. 7, a method for associating a video image of link information with a menu screen and arranging it in a series of video images will be described. The video image 13 includes video images N, O, P, Q, and R for viewing and video images M, U, S, and T not for viewing. Video image O
And Q are desired images, video image S is a notification image of desired image O, and video image T is a notification image of desired image Q. The video image M is a video image formed as a menu screen, which is a list information of a section code of a desired image. The video image U is a video image of the link information and the menu screen M
And place it as the next video.

The identification information indicating the notification image and the data of the division code of the desired image are formed by using white and black of the video image as a unit of information and corresponding to the high and low luminance levels of the video signal. Thus, the video signal of the notification video F and the video signal of the notification video G can be formed. When a desired video is recorded as a moving image, it is necessary to arrange a start notification video at the beginning of the desired video and an end notification video at the end of the desired video. The video image 4 can be recorded on a recording medium such as a video tape or a DVD. The video image is reproduced from a reproducing device of the recording medium, and the video signal is input to the viewer-side device 2 so that it can be used offline. is there. It is also possible to record this video image 4 on a recording medium without broadcasting it as a television program, and to provide it directly as a packaged product. In the present embodiment, an example in which terrestrial radio waves are used as the television signal transmission path has been described. However, the television signal transmission path includes a wired transmission path and a wireless transmission path. An example of broadcasting is CATV, and an example of television broadcasting using a wireless transmission path is satellite broadcasting.

(Embodiment 2) FIG. 2 shows an example in which a notification image is formed as a single image that can use all the image signals in a display area of a television image. In this example, a video frame is horizontally divided into 30 groups, and the notice video is formed by a black and white video pattern in units of this group. The first group H is identification information indicating the start of a notification video.
The second group I is information on the serial number of the notification video. The third group J is information on a division code of a desired video. The fourth group is the ID number of the broadcasting station, 5
The second group is television program numbers. The sixth group is a quiz number, and the seventh group is a telephone number to which an answer is sent. The eighth group is identification information indicating the end of the notification video. By forming the notification image as a white and black image pattern, white can be detected as HIGH and black can be detected as LOW as a video signal in the form of a pulse signal. The classification code of the desired video can be classified into a video to be recorded and a video to be selected and recorded by the viewer side device when the viewer device is ready to record a video video. For example, an advertising company sets a specific division code so as to record a specified advertisement screen without fail, and incorporates this division code as a desired image into a viewer-side device provided to viewers free of charge.

An embodiment in which an annunciation image is formed using an NTSC video signal will be described below. In the NTSC standard television system, a frame signal of one screen is composed of 525 horizontal scanning lines, and the image of one frame is displayed on the television screen by a skipping operation using a video signal of an odd field and a video signal of an even field. Is displayed as The video display signals of the odd field are 240 horizontal scanning line signals from the 23rd line to the 262nd line, and can be used to form a signal of the notification image. When 240 consecutive horizontal scanning lines of the odd field are divided into eight groups as one group, 30 groups are formed, and the following notification image signals can be formed in units of these groups.

The first group forms a signal indicating the start of the announcement video. The signal of the serial number of the notification image is formed in the second group. In the third group, a signal of a division code of a desired image is formed. The fourth group forms the signal of the ID number of the television broadcast station. The fifth group forms the signal of the number of the television program. A signal representing the timing of recording the desired video is formed in the sixth group. A signal representing the number of desired videos to be recorded in the seventh group is formed. The eighth group forms the signal of the identification code of the rating survey company. The ninth group forms a signal indicating the telephone number of the rating company. The tenth group forms a signal indicating the product code of the advertising product. The eleventh group forms a signal indicating the price of the advertising product. The twelfth group forms a signal of the identification information of the company to which the advertisement product is ordered. The 13th group forms a signal indicating the telephone number of the order destination of the advertisement product. 1
A signal indicating the end of the notification image is formed in the fourth group.

A signal in which all the horizontal scanning lines included in the first group are composed of ten white pulse signals is used as a start signal of a notice image. Such a video image can be formed by horizontally arranging and drawing ten white rectangles in the 23rd to 30th horizontal scanning lines on a black screen. Similarly, from the second group, 14
A video signal of the third group can be formed. Further, the pulse signal of the horizontal scanning line can be formed by using the same means as that for closed captioning or text broadcasting. In this case, since different digital signals can be superimposed on each horizontal scanning line, more detailed information can be transmitted since one group includes eight horizontal scanning lines. By forming the same horizontal scanning line signal as in the odd field in the even field, the notification image can be formed as a frame image.

(Embodiment 3) FIG. 3 shows an embodiment in which a notice image is formed from a digital broadcast video image. MPEG

When the notification image is formed as an MPEG-1 or MPEG-2 image, the notification image can be formed as a clear image if a block or a macroblock, which is a unit of the compression processing of the image signal, is used as the image formation unit.

In the MPEG-2 main level format, 44 macroblocks are arranged side by side as a slice, and a picture of one screen is composed of 30 slices. When the notification video is formed in the MPEG-2 main level format, the slice included in the
It is formed by assigning white and black video to four macro blocks. An MPEG-2 main level video image is composed of 480 horizontal scanning line signals, which are divided into 30 partial frames in units of 16 continuous horizontal scanning line signals. This partial frame corresponds to a slice, and the partial frame obtained by equally dividing the video portion of the horizontal scanning line signal into 44 parts corresponds to a macroblock.

That is, as shown in the video frame of FIG. 3, when a video frame composed of 480 horizontal scanning line signals is divided into 30 rows and 44 columns, each cell corresponds to a macro block. A row composed of 44 cells corresponds to a slice. Then, by forming a white or black image in each cell, the notification image in FIG. 3 can be formed. As the content of the notification video, for example, a video signal indicating that the partial video h formed using the first row of cells is a notification video, and the partial video i formed using the second row of the grid is A video signal indicating a classification code of a desired video,
The partial video j formed using the cells in the third row is a video signal of additional information necessary for using the desired video. The notification image formed as the image of the white and black luminance signals is transmitted after being converted into an MPEG-2 image data format in units of macroblocks. Notice video is MPEG-
In the case of forming an image in units of 1 or MPEG-2 block or macroblock, data of the block or macroblock can be directly generated as numerical data. Digital broadcast video signals are subjected to various types of data compression processing, and by setting the formation unit of the video video data stream as the formation unit of the notification video,

When the desired video to be the notification video is continuous for 150 frames, the partial video of the notification video can be inserted one by one into the video of the first seven frames. With such a configuration, the notification video displayed on the television screen can be made insignificant.

In a moving picture television program, before and after images may be completely changed when a scene is switched, but usually similar images often continue. Focusing on this point, in order to make it easier to detect the notification video, the notification video is divided into a plurality of parts, and the divided notification video is formed as a video that changes extremely mutually. Can be transmitted as a partial video of the video. For example, if the announcement video is 4
The image is divided and an identification image indicating that the image is an announcement image is formed as four extremely changing partial images.
Incorporation into a single image facilitates detection of the notification image. In addition, since the notification video signal can be transmitted as a small partial video, visibility can be reduced.
