Problems solved by technology

However, the technical solutions disclosed in the prior art only realize the distribution of single-channel TS stream digital TV, and are only aimed at digital TV signals of the TS stream type, and cannot broadcast non-TS stream digital TV programs like CMMB, and there is no specific multi-terminal The routing and forwarding function cannot meet the needs of multiple terminals to watch TV programs online at the same time, and there are great limitations in practical applications

Embodiment 1

[0035] see image 3 , which is a schematic diagram of internal module connections in Embodiment 1 of the router for multicasting digital television signals according to the present invention. The router 1 for multicasting digital TV signals in Embodiment 1 includes a signal receiving unit 11 , a control unit 12 , a stream analysis unit 13 , a data processing unit 14 , a data forwarding unit 15 and a network data receiving unit 16 . The control unit 13 controls the starting signal receiving unit 11, and after the signal receiving unit 11 receives the digital television signal, it transmits to the CMMB code stream analysis unit 12, then transmits to the data processing unit 14, performs data processing, and finally transmits to the data forwarding unit 15, Perform IP routing and forwarding. The network data receiving unit 16 receives 3G / 4G or broadband Internet IP data, and directly transmits it to the data forwarding unit 15 for IP routing and forwarding.

Abstract

The invention relates to a router for multi-channel broadcasting digital television signals, comprising a signal receiving unit, a code stream analysis unit, a data processing unit and a data forwarding unit; the signal receiving unit receives a CMMB digital TV signal in a non-TS code stream format; the code stream analysis The unit includes a CMMB bit stream analysis module, which receives the CMMB digital TV signal sent by the signal receiving unit, and analyzes the audio and video data and program information of the program in the MFS bit stream; the data processing unit receives the audio and video of the program sent by the CMMB bit stream analysis module. The video data and program information are converted into TS stream standard data, and IP packet encapsulation is performed on the converted program TS code stream data; the data forwarding unit forwards the IP data packet to the user equipment with program request. The invention can realize the reception of CMMB digital TV signals and simultaneous viewing by multiple users.

Description

technical field [0001] The invention relates to the field of digital TV communication and broadcasting, in particular to a device and a broadcasting method for realizing multi-channel broadcasting of digital TV signals through IP routing. Background technique [0002] With the advancement of communication technology, broadcast digital TV services have also entered a stage of rapid development and popularization, providing users with a large number of diverse TV programs. Broadcast digital TV technology has different standards in different countries and regions. According to different networks, it can be divided into cable digital TV, satellite digital TV, and terrestrial digital TV; according to different encapsulation formats, it can be divided into TS stream format, such as DVB-C / T / S / H, ASTC, ISDB-T and DTMB standards, and non-TS stream formats, such as the my country Mobile Multimedia Broadcasting CMMB standard independently developed by China. [0003] Transport Stream ...
