Embodiment 1

[0108] The transmission code stream of the present invention is transparent to the wireless sending equipment. After the transmission code stream reaches the wireless transmission device through the transmission network, the wireless transmission device sends it to the wireless terminal intact. The transmission network in this solution needs to use a digital transmission network, such as a metropolitan area network or an IP network. Figure 6 is an example of transmission using a metropolitan area network, which uses DS3 signals to transmit digital TV streams.

[0109] As shown in Figure 7, it is a schematic structural diagram of the mobile video broadcasting system of this embodiment. It can be seen from the figure that the system structure of this embodiment specifically includes the following parts:

[0110] Cable TV system: This part is basically the same as the existing technology, and is used to produce and transmit video. The cable TV system sends the produced video to ...

Embodiment 2

[0137] This embodiment adopts encoding that can be carried and transmitted on multiple protocols, such as MPEG-4 and H.264. After the video data is video coded, the encoding of the transmission code stream is no longer performed. Each transmission code stream or each multiplexed code stream only carries one video program, and each video program transmission code stream or multiplexed code stream directly passes through the transmission network. A sub-signal or IP network is sent to the wireless broadcasting system of the mobile video broadcasting ground transmission unit. The wireless broadcasting system does not need to provide any demultiplexer or multiplexer, and can multiplex the bearer signal to different carrier frequencies. As shown in FIG. 10 , it is a schematic structural diagram of this embodiment, and it can be seen from the figure that relevant parts such as allocation matrix, scrambling, and multiplexer are omitted.

[0138] According to the flow chart shown in Fi...

Embodiment 3

[0155] The schematic diagram of the network in this embodiment is the same as that in Embodiment 1. The difference from Embodiment 1 is that a demultiplexing device for transmitting code streams is built in the wireless sending device, and the wireless device directly sends the demultiplexed program code streams.

[0156] The wireless broadcast system demultiplexes the transmission code stream, and the wireless broadcast equipment includes a mobile video broadcast program distribution unit and a mobile video broadcast ground transmission unit. The mobile video broadcast program distribution unit directly sends the program code stream according to the carrier frequency configuration of the wireless broadcast system, and then assembles different multiplexed code streams into wireless broadcast frames and distributes them to the mobile video broadcast ground transmission unit, and the mobile video broadcast ground transmission unit Different program code streams can be sent on di...

Abstract

This invention relates to a mobile video broadcast system and a method, in which, said system includes a wire TV system processing and transmitting video and a mobile video broadcast program distributing unit, a mobile video broadcast ground sending unit and a mobile video broadcast terminal. Said method includes: a, the wire TV system factures and sends video code streams to the mobile video broadcast program distributing unit, b, the distributing unit assembles said video code stream to radio broadcast frames to be transmitted to the mobile broadcast ground sending unit by the radio transmission net, c, the ground sending unit sends the radio broadcast frames to the mobile video broadcast terminal, d, the terminal operates the video play.

Description

technical field [0001] The invention relates to the field of signal transmission, in particular to a mobile video broadcasting system and a mobile video broadcasting method. technical background [0002] In today's life, digital TV has become an important part of people's life. As shown in Figure 1, the current digital TV system is roughly divided into two processes: video production and video transmission. The video production process is roughly: first record a video, such as an image tape, and then perform digital TV encoding on the analog video by the encoder to produce a high-definition digital video. For example, a video is produced as MPEG (Motion picture expertsgroup, Animation Experts Group)-2TS (Transmit Stream, transmission stream), MPEG-4 program stream. If the quasi-on-demand mode is supported, the digital video is stored on the video server, and when on-demand in the future, it is directly transferred from the video server to play, otherwise the digital TV sign...
