Problems solved by technology
[0006] In the prior art videophone, during a call, both parties can see the video image captured by the other party through the camera in real time, and at the same time hear the audio sound captured by the other party through the microphone. When the image and sound are poor, there is no better way to deal with it, so the existing technology needs to be improved

Embodiment Construction
[0027] The present invention provides a method and device for controlling audio and video data streams based on a mobile network videophone. In order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples .
[0028] In order to solve the problem of poor image and sound during the call caused by network signals or movement during the videophone call on the mobile network, the present invention saves bandwidth and obtains a clear audio signal by activating the radio function at the calling user end The purpose, its core idea is: first configure the bit error rate threshold of audio and video frames through the configuration module of the calling user end, when the calling user end and the called user end find that the image and sound are poor during the call , when the calling user terminal detects that the bit err...

The invention provides a mobile network visual telephone (VT)-based method for controlling audio and video data stream and a device thereof. The method comprises the following steps: a configuration module on a caller side is configured with a bit error ratio threshold of an audio and video frame; the call side sets up communications with a called side, and sends and receives audio and video datastream; and when the bit error ratio of the received audio and video frame is within the upper and the lower limits of the bit error ratio threshold, the caller side prompts to activate an audio reception function. By activating the audio reception function, the caller side only receives audio data, so as to achieve the purposes of saving bandwidth and acquiring clear audio signals. Meanwhile, after activating the audio reception function, a user can also inactivate the audio reception function at any time, and the activation and inactivation of the audio reception function can not cause any impact on the visual telephone, so as to bring the user flexible choice and facilitate the use.
Description
technical field [0001] The present invention relates to a method and device in the field of mobile communication network 3G terminal technology, more specifically, a method and device for controlling audio and video data streams based on mobile network videophone. Background technique [0002] In the prior art, with the development of computer technology and third-generation mobile communication technology (3G), the processing capacity of client computer equipment is more and more powerful, and the real-time transmission technology of video data through mobile communication network is relatively mature; , the wireless videophone based on circuit domain transmission is relatively perfect both in terms of market and technology. The biggest use of 3G network is synchronous communication, and synchronous communication is applied to videophone. Videophone is an important application in the 3G era. At present, 3G The mobile phone is an important terminal to realize this applicatio...
