Abstract

The invention relates to a method for adding voice into voice video document, which comprises: the mobile terminal extracts the memorized voice video document to be decoded, to obtain the voice data and video data; using the voice picker of mobile terminal to collect the voice signal; processing the voice signal to obtain the sent voice data; using the coder to code the sent voice data and video data, based on the code protocol to form the sent document. The invention layers the real-time collected voice signal and video signal and mixes frequency when the mobile terminal sends out voice video document, to process coding and form new voice video data flow document, to make the receiver be able to play received voice video document, and listen the synchronously transmitted voice.

Description

technical field

[0001] The present invention relates to a method for superimposing voice in sending audio and video files, especially in a mobile communication system supporting videophone, when one visual mobile terminal plays pre-stored audio and video to another visual mobile terminal A method for superimposing real-time voice information in the audio and video file when the file is created. Background technique

[0002] With the use of mobile communication networks (such as 3G networks) that support videophones, mobile users can not only communicate with each other through videophone terminals, but also transmit or play audio and video files pre-stored in mobile terminals. file (DV file).

[0003] Because in the mobile communication network that supports videophone, the signal transmission between the two parties is different from the data stream transmission method in the previous 2G network, but uses the method of sending data packets to achieve massive video and audi...
