Example Embodiment

[0043] Figure 3 to Figure 4 It shows a flow chart of the recording method for mobile TV of the present invention. According to the digital mobile TV playback process, the present invention reorganizes the separated audio and video into common media formats such as AVI and MP4 in chronological order according to the timestamp, but is not limited to these two. It is stored synchronously according to the time information during playback, so that the recorded files can also be played synchronously, so that the recorded files can be played normally on handheld devices and PCs without mobile TV. The mobile TV standards in this method include CMMB and ISDB-T but are not limited to these two.

[0044] The implementation process of the present invention is as follows image 3 As shown, the audio and video decoding device is improved on the basis of the playback process, and an audio and video synthesis device is added.

[0045] The playback of mobile TV is different from the playback of ...

Abstract

The invention discloses a recording method for a mobile TV, comprising the following steps of: (1) receiving transmission data streams through mobile TV receiving equipment; (2) separating an audio and video stream with a timestamp in a program from the transmission data streams through a transmission stream analysis device; (3) respectively decoding an audio data code stream with the timestamp and a video data code stream with the timestamp from the audio and video stream by using an audio decoding device an a video decoding device; and (4) combining the audio data code stream with the timestamp with and video data code stream with the timestamp to generate a target media file. By means of the recording method disclosed by the invention, a digital program can be recorded into a file capable of being played normally by the mainstream play software on handheld equipment and a PC (Personal Computer) according to the playing process of a digital mobile TV, and therefore, the playability of a recorded file of the mobile TV is enhanced and the characteristic of saving storage space is achieved.

Description

technical field [0001] The invention relates to a recording method for mobile television. Background technique [0002] Currently, digital mobile TV playback equipment is widely used, and the recording of mobile TV programs has gradually become an essential requirement for such equipment. [0003] With the advancement of technology, digital mobile TV is developing rapidly and the market is becoming mature. Especially after the launch of the CMMB standard, it is very common to play digital mobile TV on handheld devices such as mobile phones. In addition to watching programs, users also want to save some programs they are interested in, or they don’t have time to watch the programs when they are playing, and they want to record them, and even copy the recorded files to a PC for viewing at any time. [0004] All received data streams can be saved during mobile TV recording. This method is simple and convenient to implement, but these code streams may contain the content of sev...
