Problems solved by technology

[0004] However, during the development of digital TV broadcasting services based on mobile communication systems, there is no relevant technology to describe that when users watch digital TV broadcasting programs issued by the digital TV broadcasting system, users can pass their current scene information through terminal equipment. The transmission channel of the mobile communication system is uploaded to the digital TV broadcast server, so as to participate in the live broadcast of TV programs
It can be seen that in the digital TV broadcasting service based on the mobile communication system, relevant users participate in live broadcast TV programs through the transmission channel of the mobile communication system as the transmission channel of participation data, so that the relevant technologies for realizing live program interaction are not perfect enough. , so it is necessary to further expand the existing digital TV broadcasting service technology based on the mobile communication system, so that the mobile digital TV broadcasting service can support users to interact with live programs on the side of the digital TV broadcasting system

Embodiment Construction

[0074] The design core of the technical solution of the present invention is to provide a system and method for information interaction between the user and the network side in the digital TV broadcasting service based on wireless transmission. The terminal captures the interactive scene information of the user participating in the digital TV broadcast program and transmits it to the network side through the wireless communication network (such as the third-generation or next-generation mobile communication network, etc.), and the network side superimposes the interactive information sent by the user on the currently playing In the digital TV broadcast program, it is then broadcast and distributed through the broadcast channel in the wireless communication system or wireless digital TV broadcast system. After receiving the digital TV broadcast program with interactive information superimposed on the user terminal, it can play the interactive picture mixed with participants. con...

Abstract

The present invention discloses wireless transmission based digital television broadcasting system. It contains user side and network side, wherein user side including wireless communication terminal, transmitting user participation digital television broadcast program interactive data stream to network side through wireless transmission, and receiving and playing network side down sent interactive data stream overlapped digital television broadcast program; network side including interactive processing unit, processing wireless communication terminal sent interactive data stream into data format capable of overlapping with network side digital television broadcast program data stream; data overlap device; broadcast down transmitting device. The present invention makes wireless transmission digital television system capable of realizing user with broadcast program interaction.

Description

technical field [0001] The invention relates to the technical field of digital TV broadcasting services, in particular to a wireless transmission-based digital TV broadcasting system and a method thereof. Background technique [0002] The implementation of digital TV broadcasting is generally to distribute digital TV broadcast programs through broadcast channels, and provide interactive channels for users to communicate with digital TV broadcast servers. The current forms of digital TV broadcasting services mainly include digital TV, Internet TV and mobile TV, among which the main difference between digital TV broadcasting service and traditional analog TV service is that digital TV broadcasting service can realize on-demand service and digital TV broadcasting server interaction with users. The greatest effect of digital TV broadcasting services in realizing interactive communication is that users can order programs, or users actively download information from digital TV br...
