The present invention relates to an image transmission device and an image receiving device. In particular, the present invention relates to an image transmission apparatus and an image receiving apparatus capable of providing a dynamic image in a medium using less bandwidth for image transmission.

The image transmission device transmits an image of a predetermined size to a channel (wired or wireless channel, hereinafter referred to as a channel) at a predetermined timing. The image receiving apparatus receives an image transmitted from the image transmitting apparatus from the channel and displays the image on the image display apparatus.

1 is a diagram illustrating a conventional image transmission and reception timing diagram.

As shown in FIG. 1, the image transmitting apparatus transmits images at n second intervals, and the image receiving apparatus receives the images and displays the images at the n second intervals.

For example, a medium such as a TV that provides a video has very small n of 1/24 to 1/60 seconds. Such a medium requires a lot of bandwidth instead of providing a video service. However, a medium that cannot allocate a lot of bandwidth to image transmission cannot make n small, such as a TV.

Media that cannot allocate a lot of bandwidth for image transmission transmit with a large value such as 2 or 3 seconds. In this case, the image receiving apparatus displays the received image in a slide show format. However, such slideshow image display has a limitation in providing dynamic information.

In particular, DMB audio services provide a means to transmit images, but DMB audio streams use most of the band for sound transmission, so images cannot be transmitted at high speed. Therefore, even though the DMB audio receiver had an image display device, only the slideshow format was displayed.

The image receiving device 300 is a terminal device capable of receiving a divided image and reproducing it according to a reproduction rule broadcast together.

The general image receiving apparatus 400 is a terminal apparatus that receives a normal image and reproduces the received image without special image processing. The general image receiving apparatus 400 may not reproduce the divided image according to the reproduction rule even when the divided image and the reproduction rule are received.

Next, the configuration of the image transmission device 100 will be described in detail.

As shown in FIG. 2, the image transmission apparatus 100 includes an image storage unit 110, a split image generation unit 120, a split image storage unit 130, a packetizer 140, and a transmitter 150. .

The image storage unit 110 stores images that are objects to be broadcasted. The image stored in the image storage unit 110 may be an image generated by the camera 10 or may be an image provided from the contents providing apparatus 20 of a contents provider CP.

The divided image generator 120 receives a plurality of images from the image storage unit 110 according to an image reproduction rule and generates a divided image. Here, the divided image refers to an image in which a plurality of images are arranged at respective positions divided by dividing one image plane into a plurality. Although a divided image includes a plurality of images, it is conceptually different from a plurality of images because it is treated as a data unit on a computer. Specific embodiments of the split image will be described later.

The divided image storage unit 130 stores the divided image generated by the divided image generator 120. In addition, the divided image storage unit 130 may directly receive and store the divided image from the camera 10. The divided image storage unit 130 may directly receive the divided image from the contents providing apparatus 20 of the contents provider CP.

The packetizer 140 receives the divided images to be broadcast from the divided image storage unit 130 according to a broadcast schedule and generates a broadcast packet of a type suitable for broadcasting. In this case, the broadcast packet may include an image reproduction rule to be described later. In addition, the image reproduction rule may be broadcast in a separate broadcast packet. Meanwhile, the image reproduction rule may be reflected in the file name of the image as described below.

The transmitter 150 transmits the broadcast packet generated by the packetizer 140 to the broadcast network 200.

Next, the image receiving apparatus 300 will be described with reference to FIG. 3.

3 is a block diagram illustrating an image receiving apparatus 300 according to an embodiment of the present invention.

The image receiving apparatus 300 according to the embodiment of the present invention includes a receiving unit 310, an image buffer unit 320, an image reproduction rule storage unit 330, an image reproduction unit 340, and an image display unit 350. .

The receiver 310 receives a broadcast packet from the broadcast network 200.

The image buffer 320 stores the divided image included in the broadcast packet received by the receiver 310.

The image reproduction rule storage unit 330 stores the image reproduction rule included in the broadcast packet received by the receiver 310.

The image reproducing unit 340 reproduces the divided image stored in the image buffer unit 320 in the image display unit 350 according to the image reproducing rule stored in the image reproducing rule storage unit 330.

The image display unit 350 is an apparatus for displaying an image, for example, a liquid crystal display (LCD). In addition, the image display unit 350 may be a stereoscopic image display device. As an example of a stereoscopic image display device, an image display device having a lenticular film or a parallax barrier type image display device may be used. Can be mentioned. An image display apparatus having a lenticular film attached thereto will be described with reference to FIG. 4, and a parallax barrier image display apparatus will be described with reference to FIG. 5.

4 is a diagram illustrating an image display device to which a lenticular film is attached.

As shown in FIG. 4, when the lenticular film is attached to the image display device, image information coming into both eyes is different from each other. That is, the user recognizes the planar image as a stereoscopic image by receiving different image information through both eyes. Therefore, in order for an image display device with a lenticular film to display an image as a stereoscopic image, the image of the left eye and the right eye needs different pixels. Such an image is referred to as a stereoscopic image, and the left eye pixel The three-dimensional image is created by collecting the bays separately, and the left-dimensional image is created by collecting the pixels that the right eye receives separately. Usually this left and right three-dimensional images are not broken images, but as a finished image in themselves, the two are similar but not identical. For example, if there is a three-dimensional image of a vase, when the three-dimensional image is displayed on a plane, the three-dimensional image of the vase does not appear clearly and the image is broken. However, the left stereoscopic image and the right stereoscopic image of the stereoscopic image of the vase are intact.

5 is a diagram illustrating a parallax barrier type image display device.

As illustrated in FIG. 5, a barrier filter is disposed in the image display device, so that pixels accepted by the left eye and the right eye are different from each other. Therefore, as in the image display apparatus to which the lenticular film is attached, if the image is produced such that the stereoscopic image is displayed on the left stereoscopic image and the right stereoscopic image, the parallax barrier image display apparatus may display the stereoscopic image. In particular, the parallax barrier type image display device can turn the parallax filter on and off, and can reproduce both the planar image and the stereoscopic image with one image display device.

Meanwhile, in the exemplary embodiment of the present invention, a stereoscopic image generated from a left stereoscopic image and a right stereoscopic image is used. However, more images are required to generate stereoscopic images for providing multi-view stereoscopic images. Accordingly, each of the plurality of unit images required to generate a stereoscopic image of a binocular or multiview system will be referred to as a unit stereoscopic image.

Next, an image receiving apparatus 300 according to various embodiments of the present disclosure will be described in detail with reference to FIGS. 6 to 20.

In the following embodiment, the time axis of the image buffer unit 320 refers to a time at which an image is received by the image receiving apparatus 300 and stored in the image buffer unit 320. Means the time displayed on the image display unit 350.

6 is a diagram illustrating an example of a divided image according to an exemplary embodiment of the present invention.

Hereinafter, the divided image as shown in FIG. 6 will be referred to as a stereoscopic divided image. As shown in FIG. 6, when the three-dimensional segmented image is displayed on the flat image display device, two similar images AL and AR are displayed on the left and right sides of the display device. In this case, when the image AL displayed on the left is a left stereoscopic image and the image AR displayed on the right is a right stereoscopic image (or an image displayed on the left is a right stereoscopic image and an image displayed on the right is a left stereoscopic image). , The image receiving apparatus 300 may implement a stereoscopic image using the stereoscopic divided image. When the left stereoscopic image of the stereoscopic image A is called AL and the right stereoscopic image is called AR, the stereoscopic divided images that can be made into the AL and the AR are displayed as <AL, AR>.

7 shows an example of a segmented image according to the format of FIG. 6. A stereoscopic image may be generated through FIG. 7.

8 is a diagram illustrating another example of a divided image according to an exemplary embodiment of the present invention.

Unlike in FIG. 6, in the image format illustrated in FIG. 8, the left stereoscopic image AL and the right stereoscopic image AR are disposed above and below the image. However, since the image format shown in FIG. 8 differs only in the arrangement of each stereoscopic image, its function is the same as the image format shown in FIG. 6, so that the divided image shown in FIG. 8 will also be referred to as a stereoscopic divided image.

9 is a diagram illustrating an operation of the image receiving apparatus 300 according to the first embodiment of the present invention.

As shown in FIG. 9, in the first embodiment of the present invention, the three-dimensional segmented image is stored in the image buffer unit 320 every second. In FIG. 9, the stereoscopic divided images <AL, AR>, <BL, BR>, <CL, CR>, <DL, DR>, ... are stored in the image buffer 320 at one second intervals.

The image reproduction rule according to the first embodiment of the present invention is a stereoscopic slideshow mode, which displays a stereoscopic image represented by the stereoscopic divided image on the image display unit 350 whenever a stereoscopic divided image is received. will be. According to the image reproduction rule, in the stereoscopic slice mode, a predetermined delay from the reception of the stereoscopic divided image to the reproduction may be provided, or may be reproduced at a specific time.

According to the stereoscopic slide show mode, when the image receiving apparatus 300 receives the stereoscopic divided image <AL, AR>, the image reproducing unit 340 generates the stereoscopic image A with the stereoscopic divided image <AL, AR>. This is displayed on the image display unit 350. In addition, when the image receiving apparatus 300 continuously receives the stereoscopic divided images <BL, BR>, <CL, and CR>, the image reproducing unit 340 generates the stereoscopic images B and C and displays the image displaying unit 350. Display on.

As a result, the stereoscopic image is displayed in the slide format on the image display unit 350. On the other hand, since the general image receiving apparatus 400 displays the divided image itself, two images divided left and right (or up and down) are displayed on the screen, and the divided images are displayed in a slide format. If the broadcaster broadcasts the image in the stereoscopic image format instead of the divided image format, the image receiving apparatus 300 equipped with the stereoscopic display apparatus may reproduce the stereoscopic image, but the general image receiving apparatus without the stereoscopic display apparatus ( 400 reproduces the distorted image. Therefore, if the broadcaster broadcasts the divided image format and its reproduction rule, the general image receiving apparatus 400 displays two images by dividing the screen but does not reproduce the distorted image. Therefore, the broadcaster may broadcast a 3D image even when the general image receiving apparatus 400 is used.

Meanwhile, in FIG. 9, the image transmitting apparatus 100 transmits the stereoscopic divided images to the image receiving apparatus 300 at the interval of 1 second, but the image transmitting apparatus 100 is the stereoscopic divided image at a speed of about 1/30 seconds, for example. If the image is transmitted and the stereoscopic divided image received by the image receiving apparatus 300 is displayed at the same speed, the image receiving apparatus 300 may be provided with a video service of the stereoscopic image. Hereinafter, this operation mode of the image receiving apparatus 300 will be referred to as a stereoscopic video mode. In particular, in this case, the general image receiving apparatus 400 may play two moving images in which the screen is divided into left and right (or up and down). Therefore, even when both the image receiving apparatus 300 and the general image receiving apparatus 400 are used, the broadcaster may provide a 3D video service by broadcasting an image in a divided image format.

Since the stereoscopic slide mode and the stereoscopic video mode are only differences in the reproduction interval of the unit images, the stereoscopic slide mode and the stereoscopic video mode will be collectively referred to as stereoscopic reproduction mode.

10 is a diagram illustrating an operation of the image receiving apparatus 300 according to the second embodiment of the present invention.

As shown in FIG. 10, the stereoscopic divided image is stored in the image buffer unit 320 every second. In FIG. 10, the stereoscopic divided images <AL, AR>, <BL, BR>, <CL, CR>, <DL, DR>, ... are stored in the image buffer unit at one second intervals.

The image reproduction rule according to the second embodiment of the present invention is a stereoscopic repeating video mode. In this stereoscopic repeating video mode, the image reproducing unit 340 images two stereoscopic images represented by a stereoscopic divided image as a repeating video at 0.1 second intervals. It is displayed on the display unit 350. Here, the repeated video refers to an image that gives a viewer a dynamic effect by repeatedly playing two or more images. In addition, two or more images constituting one repeated video will be referred to as image groups hereinafter. That is, in FIG. 10, the stereoscopic image A and the stereoscopic image B become one image group, and the stereoscopic image C and the stereoscopic image D become another image group.

In FIG. 10, when the image receiving apparatus 300 receives the stereoscopic divided images <AL, AR>, and <BL, BR>, the image reproducing unit 340 generates stereoscopic images A and B, and displays the two stereoscopic images by 0.1. The image display unit 350 is repeatedly displayed at the interval of seconds. Then, when the image receiving apparatus 300 receives the stereoscopic divided images <CL, CR> and <DL, DR>, the image reproducing unit 340 generates stereoscopic images C and D and performs these two stereoscopic images for 0.1 second. Repeated intervals are displayed on the image display unit 350.

As a result, the stereoscopic image is displayed in the repeated video format on the image display unit 350. Meanwhile, the general image receiving apparatus 400 displays two images separated into left and right (or up and down), and the divided images are displayed in a slide form. Therefore, even when both the image receiving apparatus 300 and the general image receiving apparatus 400 are used, if the image is broadcast in the form of a divided image, the broadcast service provider does not display the distorted image, so the broadcaster provides a stereoscopic repeating video service. Can be provided.

11 is a diagram illustrating an operation of the image receiving apparatus 300 according to the third embodiment of the present invention.

The image receiving apparatus 300 according to the third exemplary embodiment of the present invention displays a repeated video through three stereoscopic divided images.

12 is a diagram illustrating an operation of the image receiving apparatus 300 according to the fourth embodiment of the present invention.

As shown in FIG. 12, if the image reproducing rule supports the image receiving apparatus 300, the image receiving apparatus 300 may generate a stereoscopic image by receiving a stereoscopic divided image and perform various types of display therethrough.

13 is a diagram illustrating still another example of a divided image according to an exemplary embodiment of the present invention.

The image format shown in FIG. 13 includes two images arranged on the left side and the right side (or up and down). The images disposed on the left and right sides are images that can be reproduced when the repeated video is repeatedly displayed at a speed that can be expressed as a video. Such a divided image is called a repeated video segmented image. When the image constituting the repeated video A is A1 or A2, the repeated video split image may be expressed as <A1, A2>.

14 is a diagram illustrating an operation of the image receiving apparatus 300 according to the fifth embodiment of the present invention.

As illustrated in FIG. 14, a repeated video segmented image is stored in the image buffer unit 320 every 1 second. In FIG. 14, repeated video segment images <A1, A2>, <B1, B2>, <C1, C2>, <D1, D2>, ... are stored in the image buffer unit 320 at intervals of 1 second.

The image reproduction rule according to the fifth embodiment of the present invention is to display two images included in the repetitive moving image segmentation image on the image display unit 350 as repetitive moving images at 0.1 second intervals.

That is, in FIG. 14, when the image receiving apparatus 300 receives the repeated video segmentation images <A1 and A2>, the image reproducing unit 340 separates the images A1 and A2 from the repeating video segmentation images <A1 and A2>. The two moving images are repeatedly displayed at the image display unit 350 at 0.1 second intervals to reproduce the repeated moving image A. FIG. When the next image receiving apparatus 300 receives the repeated video segmentation images <B1 and B2>, the image reproducing unit 340 separates the images B1 and B2 from the repeating video segmentation images <B1 and B2> and divides the two images by 0.1. The repeated moving image B is reproduced by repeatedly displaying the image display unit 350 at the interval of seconds. Thereafter, the image receiving apparatus 300 performs the same process with respect to the repeated video segment images <C1, C2>, <D1, D2>, ... to reproduce the repeated video. In this case, when the unit image separated from the repeated video segmentation image is larger or smaller than the screen size of the image display unit 350, the image playback unit 340 zooms out or zooms in to the unit image to display the screen size. The display may be displayed according to the display position, or the display may be cut by displaying a specific position. In this case, a scroll bar may be placed to move the display position of the unit image to display the display.

As a result, the repeated video is displayed on the image display unit 350. Meanwhile, the general image receiving apparatus 400 displays two images separated into left and right (or up and down), and these divided images are displayed in a slide form. Since the divided image will be an image having a size larger than that of the general image receiving apparatus 400, the general image receiving apparatus 400 may zoom in to display the received image and display the received image. A specific position (eg, upper left) of the image may be cropped and displayed. In this case, a scroll bar may be provided to move and display the display position of the unit image. Therefore, even when both the image receiving apparatus 300 and the general image receiving apparatus 400 are used, the broadcaster can broadcast the image in the divided image format.

15 is a diagram illustrating various examples of a repeated video segmentation image according to an embodiment of the present invention.

FIG. 15A illustrates a format of a repeated video segmentation image in which one image is divided into three and images that constitute a repeating video are arranged in each. In this case, the repeated video is reproduced as three images.

FIG. 15B shows a format of a repeating video segmentation image in which one image is divided into four and the images constituting the repeating video are arranged. In this case, the repeated video is reproduced as four images.

FIG. 15C is an image format in which one image is divided into four equal parts up and down, left and right, and an image constituting a repetitive moving picture is arranged in each. In this case, the repeated video is reproduced with four images.

As shown in FIG. 15, the repeated video segmented image may include two or more images.

16 is a diagram illustrating another example of a divided image according to an embodiment of the present invention.

In the image format shown in Fig. 16, one image is divided into four parts, and images A1_L, A1_R, A2_L, and A2_R are disposed at each position. Here, images A1_L and A1_R are left stereoscopic images and right stereoscopic images of stereoscopic image A1, and images A2_L and A2_R are left stereoscopic images and right stereoscopic images of stereoscopic image A2. The stereoscopic image A1 and the stereoscopic image A2 are images constituting the repetitive moving image A. As such, the image format illustrated in FIG. 16 is referred to as a repeated stereoscopic divided image for convenience.

17 is a diagram illustrating an operation of the image receiving apparatus 300 according to the sixth embodiment of the present invention.

As shown in FIG. 17, in the sixth embodiment of the present invention, a repeated stereoscopic divided image is stored in the image buffer unit 320 every second. That is, in FIG. 17, repetitive stereoscopic divided images <A1_L, A1_R, A2_L, A2_R>, <B1_L, B1_R, B2_L, B2_R>, ... are stored in the image buffer unit 320 at intervals of 1 second.

The image reproduction rule according to the sixth embodiment of the present invention is to display two stereoscopic images included in the repeated stereoscopic divided images on the image display unit 350 as a repetitive moving image at 0.1 second intervals.

According to the image reproduction rule, when the image receiving apparatus 300 receives the repeated stereoscopic divided images <A1_L, A1_R, A2_L, A2_R>, the image reproducing unit 340 performs the repeated stereoscopic divided images <A1_L, A1_R, A2_L. , Stereoscopic images A1 and A2 are generated from A2_R>, and the stereoscopic repeated videos A are reproduced by repeating the two stereoscopic images at 0.1 second intervals and displaying them on the image display unit 350. Then, when the image receiving apparatus 300 receives the repetitive stereoscopic divided images <B1_L, B1_R, B2_L, and B2_R>, the image reproducing unit 340 performs the stereoscopic images from the repetitive stereoscopic divided images <B1_L, B1_R, B2_L, and B2_R>. The stereoscopic repetitive moving image B is reproduced by generating B1 and B2 and displaying them on the image display unit 350 by repeating the two stereoscopic images at 0.1 second intervals.

As a result, the repetitive video of the stereoscopic image appears on the image display unit 350. On the other hand, the general image receiving apparatus 400 is to be displayed in the form of a slide divided image (divided image). Since the divided image will be an image having a larger size than the normal image receiving apparatus 400 can display, the general image receiving apparatus 400 crops a specific position (for example, the upper left) of the received image (crop). Can also be displayed. Therefore, even when both the image receiving apparatus 300 and the general image receiving apparatus 400 are used, the broadcaster may broadcast the image in the divided image format.

Next, an image reproduction rule according to an embodiment of the present invention will be described in detail with reference to FIGS. 18 and 19.

The repeating video mode is a mode in which a plurality of unit images constituting a repeating video is extracted from the received divided image and the unit images are repeatedly played back. There are two types of three-dimensional repeated video mode. The first stereoscopic repeating video mode is a mode for generating two or more stereoscopic images from one segmented image and repeatedly playing the generated two or more stereoscopic images. The second stereoscopic repeating video mode is a mode for generating a plurality of stereoscopic images from the plurality of divided images and repeatedly playing the generated stereoscopic images.

The number of playback images field P105 is a valid field in the repeat video mode or the stereoscopic repeat video mode. The playback image number field P105 contains the number of images constituting the repeated video.

19 illustrates another example of a broadcast packet including an image reproduction rule according to an embodiment of the present invention.

The broadcast packet P200 of FIG. 19 includes a header field P201, a split image file name field P202, and a split image row data field P203.

Since the header field P201 and the split image row data field P203 are the same as the header field P101 and the split image row data field P110 of the broadcast packet P100 illustrated in FIG. 18, description thereof is omitted.

The split image file name field P202 is an area containing a file name of a split image included in the broadcast packet P200. Normally, an image file name is composed of a combination of characters having an ASCII code value, such as 'picture.jpg'. In the embodiment of the present invention, the meaning of the character value of each position of the file name is given meaning so that the image reproduction rule is included in the file name of the split image. In the case of the broadcast packet P100 including the image reproduction rule as shown in FIG. 18, there may be an image receiving apparatus that cannot interpret this. However, if the image reproducing rule is transmitted through the file name, the image receiving apparatus which does not recognize the file name as the image reproducing rule processes the split image by the normal file name. Therefore, even when both the image receiving apparatus 300 and the general image receiving apparatus 400 are used, the broadcaster may broadcast the reproduction rule together while broadcasting the image in the divided image format.

Hereinafter, an example in which the image reproduction rule is reflected in the file name will be described.

First, when the image is a split image, the file name starts with 'DP' indicating the split image.

The number of unit images included in the divided image is represented by a number. For example, if there are two unit images included in the split image, the file name is represented by '2'.

Image placement information is created in advance in several types and mapped to the alphabet. For example, the arrangement of the divided images illustrated in FIG. 6 is' A ', the arrangement of the divided images illustrated in FIG. 8 is' B', and the arrangement of the three divided images illustrated in FIG. 15 is' C ',' D ',' E 'and the like.

The alphabet is also used to indicate the image playback mode. For example, the stereoscopic reproduction mode may be displayed as 'A', the repetitive moving image mode as 'B', and the stereoscopic repetitive moving image mode as 'C'.

Use numbers to indicate the number of images played. For example, if the number of unit images constituting the repeated video mode is three, this may be displayed as '3'.

Correlation between the broadcast packets P200 uses alphabets, and serial numbers of broadcast packets P200 having the same correlation may use numbers.

The Image Playback Interval field is displayed numerically. For example, when the image playback interval is the same as the image reception interval, it may be displayed as '000'. If the image playback interval is 3 seconds, that is, the interval at which one image is played back every 3 seconds, it can be displayed as '301', and if the image playback interval is 1/30 second, that is, 30 images per second In the case of the interval for playing back the image, it may be displayed as '130'.

The reproduction conditions of the divided images are associated with alphabets for each type. 'A' is used to indicate 'immediate reception', 'B' is used to indicate 'start playback by user', 'scheduled time', 'reach specific time', 'image receiving device ( 'C', 'D', 'E', 'F', 'G' to indicate immediately after the 'power on of 300', 'just before the power-off of the image receiving apparatus 300', and 'change of the receiving channel', respectively. 'Is used.

If the file name of the split image shown in Fig. 6 is named through such a file rule, the file name is 'DP2AA1A0000A.jpg'.

In addition, the file names of the split images <AL, AR> and <BL, BR> shown in FIG. 10 are 'DP2AC2M0110A.jpg' and 'DP2AC2M1110A.jpg', respectively.

In particular, if the file name includes a rule for reproducing the split image as shown in FIG. 19, the image reproducing apparatus for receiving the split image does not need to separately store the rule for reproducing the split image. Therefore, the image receiving apparatus for receiving the broadcast packet P200 of FIG. 19 is the same as that of FIG. 20.

20 is a block diagram illustrating an image receiving apparatus 400 according to another embodiment of the present invention.

The image receiving apparatus 400 of FIG. 20 includes a receiving unit 410, an image buffer unit 420, an image reproducing unit 440, and an image display unit 450.

Since the receiver 410 and the image display unit 450 are the same as the receiver 310 and the image display unit 350 of the image receiving apparatus 300 of FIG. 3, description thereof will be omitted.

The image buffer unit 420 stores an image included in the broadcast packet received by the receiver 410. In this case, if the broadcast packet received by the receiver 410 is the broadcast packet P200 illustrated in FIG. 19, the image buffer 420 may display the split image included in the broadcast packet P200 through a file name reflecting an image reproduction rule. Save it.

The image reproducing unit 440 reproduces the divided image stored in the image buffer unit 420 on the image display unit 450 according to the image reproducing rule reflected in the file name.
