われる。Referring to FIG. 9, a method of reproducing the moving image data stored in the memory 45 will be described with reference to FIG. Process using mouse and keyboard connected to PC 117 8
In step 1, the stored data is searched by referring to the management table in the memory 45, and a reproduction instruction is given. The retrieved compressed data is decompressed by the decompression board 43, passed to the frame memory 41 via the video board 40, and output 83 to the interactive TV 116. Further, the output screen size and output location on the TV screen (that is, on the bit map on the frame memory 41) are designated by a mouse or the like (bit map size designation / four corner coordinate position designation, output reference coordinate position designation). ) Process 84 is performed by control unit 44.

モリ４５にデ−タ圧縮蓄積されている。An interactive TV system (interactive TV 116, personal computer 117) realized by the configuration and processing shown in FIGS. 1 to 9 will be described with reference to FIG. First, the screen 91 is an example of a screen for selecting a program such as a VOD movie program or movie video on CATV. This is because the video data of the program menu is previously distributed / stored from the video server 11 via the network 110 to the memory 45 of the interactive TV system from the center of FIG. 1, and is transmitted to the TV 116 via the frame memory 41. The selection screen is displayed by outputting the screen. When the drama portion is designated with the mouse (coordinate position calculation on the bitmap 41), the control unit 44 designates destination designation (device ID number of the interactive TV 116) information and designated program number (coordinate position calculation on the bitmap 41). The result) is transmitted to the center. Based on these information, the center is shown in Figure 3.
Address table (31, 310, 311,
32, 320, 321) based on the program video data, CM video data related to the program, and home shopping video data, and the disk array 23, the disk library 2
4, and the video server 11 transmits the video data to the destination interactive TV system. These video data are compressed and stored in the memory 45 of the interactive TV system by the same processing as in FIG. 8, and the drama is broadcast (screen 92) on the interactive TV 116 by the same processing as in FIG. Further, the program image and the related C transferred together with the program image are stored in the memory 45.
Management table for M video and home shopping video (Fig. 3
A management table having the same structure as in (1) is also copied from the center and sent, and an address suitable for the memory 45 of the interactive TV system is put therein to construct it. At this time, again, all of the program, the related CM image data, and the home shopping image are compressed and stored in the memory 45 of the interactive TV system.

れる。Here, since the transmission channel of the bidirectional CATV path of VOD reaches several thousand or more, even if a program request is simultaneously made from a plurality of different interactive TV systems, the connection between each interactive TV system and the center is not possible. Done by different channels. Therefore, the center and the data transmission path are established for each channel (that is, for each interactive TV system).

なわれる。In order to like the performer's clothes (jacket) in the drama on this display screen 92 and to know the details,
Specify the clothes with the mouse. Here, a method of detecting a place / place (clothes) designated by a mouse on a moving image will be described. Outputting a moving image to the interactive TV 116 is performed via the frame memory 41 of FIG. At this time, looking at each of the frame memories 41, they are still images, not moving images. Therefore, the designated position of the mouse in the still image is detected as the bit map coordinate position of the frame memory 41 which is generally performed. Therefore, by using the same management table as shown in FIG. 4, it is determined which CM target area is the coordinate position designated by the mouse in the display frame (for example, the frame 310). As a result, the CM target at this time is referenced from the table. For example, if the position of clothes is pointed to,
It is the coordinate of 1, and CM type 111: jacket, CM type 112: tie, CM type 113: pants are designated, and the CM (description) screen 93 of the clothes is designated by the designation.
Change to This obtains the address of the memory 45 in which the video is stored in the management table similar to the management table of FIG. 4, and outputs the CM video data from the memory 45 to the interactive TV 116 by the same process as in FIG.
At this time, the CM may be interrupted and flowed separately from the screen of the drama (bitmap data of the entire display frame memory 41 is replaced with CM data), or a window display (display frame memory) may be displayed on a part of the original drama. 41
The bitmap data of a part of the area may be replaced with CM data). As a result, in the CM, the screen of the performer's clothes jacket, tie, and pants is explained on the screen 93.
Done in. When a jacket is selected on this screen 93, a jacket pattern selection screen 94 is displayed by selecting the jacket. This is performed by the same processing as the mouse selection detection and CM video reproduction described above. Here, a simulation 95 (applying one's face and figure to the jacket on the screen) is performed to see how the person will wear this jacket. This simulation
This is performed by accumulating / reproducing one's appearance by the processing of FIGS.
