In order to allow the party member of villagers' committee and village the inside participate in more easily the meeting of all kinds of policy propagandas, reflect in time the popular feelings condition of the people, native system also comprises audio/video conference platform, camera at the on-the-spot mounting strap encoder of meeting, conference telephone, by sound, picture signal is transferred to Broadcast Control management platform by all kinds of return networks, through authorizing after broadcasting, by OSS issuing command, by this media data transmission to data broadcast platform, after multiplexing, realize broadcasting of audio, video data, can realize the effect of video conferencing on the one hand, on the other hand can also be by the decision of villagers' committee, the Party's line, principles and policies, the productive life information that peasant is badly in need of is broadcast in Set Top Box by the mode of frequency modulation, by the built-in transmitter module of Set Top Box, be sent in the television set of peasant household, realize low-cost, the wide policy propaganda covering.In villager family, only a rural power grids digital TV set-top box need to be installed, just can watch and listen in real time the momentous conference of party.
In county's one-level, build audio/video conference system, meeting is continued, dispatched and monitors, at province center, build instruction delivery system, all meetings are carried out to unified management and scheduling.
In order to utilize said system, the present invention is by utilizing following method to carry out concrete configuration and use.
61) user is after installing Digital Television, according to the region of installing in set-top box recording, and CA card number record, the area information server in Broadcast Control management platform extracts user profile and area information from OSS;
62) user profile in the user profile extracting and Boss system is corresponding, the area information synchronously extracting and the area information in OSS;
63) data broadcast platform forms area code according to above-mentioned user profile and area information;
64) in the data broadcast editing server of data broadcast platform, set the naming rule of the page, and for the feature of different administrative regions, work out the different data broadcast pages;
65) data broadcast platform is inserted into area code in the privately owned descriptor of NIT table;
65) OC baling press, by the packing of media data Unified Global, forms single data broadcast packets;
67) after data broadcast stream is broadcast, Set Top Box receives data broadcast packets, shows, and parse the provincial characteristics code of oneself according to NIT;
68) Set Top Box, according to the provincial characteristics code receiving, is screened the specific data broadcast page, shows the specific data broadcast page.
When utilizing audio/video conference platform, the audio, video data gathering is when returning by return system, the area information and the user profile data that comprise collecting location, data broadcast platform accessible region domain information and user profile are to the transmission of packing of this media data so simultaneously.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, without departing from the inventive concept of the premise; can also make some improvements and modifications, these improvements and modifications also should be considered as in protection range of the present invention.
