That is, it has a basic function of inputting layout information such as HTML and displaying it as a screen, and a function of recognizing the screen as a user operation event when the user operates the screen.

Next, an example of the operation of the present embodiment will be described. In the following description, as an example of a competition broadcast, a case where a red and white song battle is broadcast will be described.

As exemplified in the flowchart of FIG. 2, the broadcasting station 100 distributes the layout information of the video and the voting screen to the individual viewer terminals 200 via the radio broadcast network 300 (step 1001, step 1001). 100
2), waiting for input from a plurality of viewers (viewer terminal 200) (step 1003), receiving input from a plurality of viewers (step 1004), totaling input received from a plurality of viewers (step 1005) Of the video screen or the voting screen reflecting the counting result and the viewer terminal 200
(Step 1006) is repeatedly executed during the broadcast.

Step 10 described above in the broadcasting station 100
An example of the detailed processing of the operations 04 to 1006 is shown in the flowcharts of FIGS.

That is, as exemplified in the flowchart of FIG. 5, the WWW connected to the Internet 400
The server 109 receives the user input information coming from the viewer terminal 200 and receives the user input information totaling table 110
(Step 1021). When a predetermined totaling timing comes (Step 1022), the user input information is totalized (Step 1023).
06 is notified of the counting result via the intranet 108 (step 1024). This series of operations is repeated.

As exemplified in the flowchart of FIG. 6, the video encoder 102 and the transmission video controller 106

It monitors whether there is a notification of the tally result from the WW server 109 side (step 1032), and when there is a notification, updates the video layout information table 107 with the notification content (step 1033).

Further, the embedding timing of the layout information is determined (step 1034), and the layout information read from the video layout information table 107 is embedded between encoded video information and the like (step 103).
5) Output to the transmitting apparatus 101. This series of operations is repeated.

On the other hand, in response to the operation of the broadcast station 100 described above, the viewer terminal 200 receives the broadcast video and the layout information of the voting screen (steps 1011 and 1012), for example, as shown in FIG. It is displayed on the display 208 in such a screen format (step 101
3) Viewers (users) via the user input device 209
(Step 1014). When an input from the viewer is detected (step 1015), the input content is transmitted to the WWW server 109 of the broadcasting station 100 via the Internet 400 (step 1016).
In step 1017, a screen reflecting the updated contents in step 1006 is displayed.

That is, in the example of the screen of the display 208 in the viewer terminal 200 shown in FIG. 7, a red group image 601 and a white group image 602, a red group voting button 603 and a white group voting button 604 are displayed in the voting screen 600. it's shown. Red group voting button 603 and white group voting button 60
4 is toggled by a predetermined selection operation by the user, and the support information of the selected side is displayed in the WWW server 10.
9 is transmitted.

At first, the red group image 601 and the white group image 602 have the same size.
In the transmission video control device 106 of the broadcast station 100, the video on the side with more support information is displayed in a large size in accordance with the fluctuation of the magnitude of the result of summing up the support information of each of the red set and the white set. The video layout information embedded in the broadcast information is sequentially updated (for example, every several seconds) so that the output volume of the set may be made proportional.

As a result, on the voting screen 600 on the display 208 of each viewer terminal 200, the video (the red group video 601 in the example of FIG. 7) on the side where more support information has been obtained is displayed larger. The magnitude relationship of the video changes according to the temporal change of the result of summing up the support information. As a result, individual viewers can watch and support the broadcast contents with a sense of reality reflecting the results of their support.

FIGS. 8, 9 and 10 show modified examples of the voting screen.

That is, in the example of the voting screen 600A shown in FIG. 8, the display state reflects the common image 605 common to the red group and the white group and the size of the support information by the viewer input of the red group and the white group. An example is shown in which a pie chart 606 that changes over time, a red set voting button 603 and a white set voting button 604 are arranged.

In the example of the voting screen 600B shown in FIG. 9, a common video 605 and a bar indicator 607 whose display state changes with time reflecting the size relationship between the support information input by the viewers in the red and white groups are shown. A text input screen 608 for a user to input a support message, and a bulletin board image 609 for displaying a support message input from a plurality of viewers selected on the broadcast station 100 side. Cheering messages entered by individual viewers
The information is transmitted from the WWW server 109 to the transmission video control device 106 and is reflected in the broadcast information. Since the support message input by the viewer is output to the display 208 of the viewer terminal 200 of all viewers, the viewer can view with high sense of reality.

The voting screen 600C of FIG. 10 shows an example in which a chat screen 610 displaying so-called chat contents by text input by a viewer is provided. Since the number of broadcast viewers is enormous, it is difficult to incorporate all chat data into broadcast information in real time and distribute it to the viewer terminal 200 for display. Therefore, for example, it is conceivable that the load is reduced by grouping the singers in each group, such as a red group, a white group, and even the singers in each group, so that each viewer belongs to a specific group. Therefore, a group selection button 611 is displayed.

The viewer uses the group selection button 611 to
Select your favorite group and join the chat. In this case, it may be incorporated in the chat data broadcast information of a plurality of groups, but in consideration of the above-described load restrictions,
The display data for the chat screen 610 may be distributed from the WWW server 109 to the individual viewer terminals 200 via the Internet 400.

7 to 10 described above, the viewer of each viewer terminal 200 can be arbitrarily selected by designation from a main menu (not shown).

(Embodiment 2) Next, with reference to FIGS. 11 to 16, another embodiment of the interactive broadcast viewing system of the present invention and its control method will be described. In the second embodiment, various display control examples in the interactive broadcast viewing system will be described. In addition, Embodiment 2
