Abstract

The invention provides a method and a device for mobile multimedia broadcast program transition. The device comprises a receiving module, a code flow conversion module and an output module which are connected in sequence, wherein, the receiving module is used for receiving the signals of mobile multimedia broadcast programs and processing the signals into mobile multimedia broadcast format code flow; the code flow conversion module is used for converting the mobile multimedia broadcast format code flow into general video format code flow; and the output module is used for outputting the general video format code flow and providing the same for a broadcasting device supporting the general video format. The method and the device for mobile multimedia broadcast program transition can broadcast the mobile multimedia broadcast programs without using a special broadcasting device.

Description

technical field [0001] The invention relates to mobile multimedia broadcast technology, in particular to a mobile multimedia broadcast program switching method and switching equipment. Background technique [0002] According to the physical form, the mobile multimedia broadcast terminal can be divided into two forms: all-in-one and external module. The all-in-one machine is the demodulation, demultiplexing, decryption, decoding and display of radio frequency signals through a single terminal, such as mobile phones, laptops, etc.; the other is an external modular terminal, which is connected to other The playback terminal (computer, TV, etc.) realizes the reception and display of mobile multimedia broadcasting programs, such as CMMB (China Mobile Multimedia Broadcasting, China Mobile Multimedia Broadcasting) TV stick, wireless network card, etc. [0003] The video format of China Mobile multimedia broadcasting is H.264. Since there are very few players supporting H.264 at pr...
