Problems solved by technology

In the 3G mobile communication system, the value-added service of videophone can be provided, but due to the limitation of bandwidth in the existing 3G network, it can only support users to make videophone calls in a low-speed environment, but when the user is in a high-speed environment (speed greater than 100km / h, such as a high-speed train), the user cannot normally make video calls

Embodiment Construction

[0026] The present invention can select whether to open the high-speed mode through the setting function of the menu. After the function is opened, the videophone of the mobile phone switches to the high-speed environment mode.

[0027] After this function is enabled, the mobile phone needs to do the following processing:

[0028] The audio part remains unchanged;

[0029] According to the H324.M protocol stack of the video phone, you can send a message with parameters to notify the other party's mobile phone that the high-speed mode has been activated here. After the other party's mobile phone receives and parses the message, it can control the encoding of the encoder to send data and reduce the frame rate. rate. It should be noted that the mobile phone of the other party must support parsing the message that requires reducing the frame rate and frame encoding size;

[0030] Notify the local encoder to reduce the size of the I video data encoding, the general encoded data i...

Abstract

The invention relates to a 3G videophone and an operating procedure thereof. The 3G videophone comprises a user interface module, a quality control module and a time stamp control module; a local user sets the mode of the 3G videophone as a high-speed mode; under the high-speed mode, the quality control module reduces the local coding speed to a first preset value and / or the local coding quality to a second preset value and reduces the decoding speed to a first preset value; by means of a time stamp with a preset mark, the quality control module requests a peer-end user to reduce the coding speed to a first preset value and / or the coding quality to a second preset value and reduce the decoding speed to a first preset value; the time stamp control module monitors the time stamp sent by thepeer-end user, and if the time stamp has the preset mark, the time stamp control module notices the quality control module to reduce the local coding speed to the first preset value and / or the local coding quality to the second preset value and reduce the decoding speed to the first preset value. By reducing the coding quality and rate of a coder, the invention makes high-speed video calls possible.

Description

technical field [0001] The invention relates to a mobile terminal, in particular to a 3G videophone and its working method. Background technique [0002] With the rapid development of mobile terminal technology, the functions and performance of mobile terminals are becoming more and more perfect, which provides a basis for the expansion of mobile terminal functions in the application field. Nowadays, mobile terminals generally have recording, photographing and video recording functions. Reasonable application of these Functions can provide users with more services. [0003] Now the mobile communication system is gradually evolving from 2G to 3G, and some 3G mobile communication systems have already started commercial use. In the 3G mobile communication system, the value-added service of videophone can be provided, but due to the limitation of bandwidth in the existing 3G network, it can only support users to make videophone calls in a low-speed environment, but when the use...
