Video conversion submodule 7-5-1-4, is mainly to change for video content, can comprise video format conversion, video proportional zoom, video resolution adjustment, encoding and decoding, a series of processing operation of encryption and decryption, completes the work for the treatment of of video.
It is to be mainly that text, picture, audio frequency, video etc. reconsolidate by each part of content of multimedia through after finishing dealing with that content of multimedia merges module 7-5-2, is reduced to a complete content of multimedia file.
Multimedia Qos optimisation strategy engine 7-6 is mainly to solve the Qos problem of multimedia in mobile environment transmitting procedure, by taking a series of guarantee strategies to improve service quality.
The first step, for the mistake occurring in Multimedia Data Transmission and mobile multi media gateway system processing procedure, multi-medium data correction module will be corrected these multi-medium datas, measure and the means of corrigendum can be taked forward error correction, backward error correction etc. method, guarantee the correctness of multi-medium data;
Second step, the multi-medium data after correction need to be further improved and strengthen, and multi-medium data compensating module is taked indemnifying measure for the details (resolution, frame data) of multi-medium data etc., promotes and strengthen the whole structure of multi-medium data;
The 3rd step, just by mobile network, send multi-medium data to mobile terminal device afterwards, now need rate adaptation module and buffering two large modules to carry out Coordination Treatment, rate adaptation module is automatically adjusted multimedia transfer rate and is dealt with network speed in mobile network environment and the variation of bandwidth resources, and by multi-medium data buffer module, coordinate rate adaptation module to coordinate the transmission of multi-medium data, make the mobile terminal device mobile multimedia data that steadily reception & disposal of smoothness completes.
As shown in Figure 5, multimedia Qos optimisation strategy engine 7-6 can be divided into four major parts such as multi-medium data correction module 7-6-1, multi-medium data compensating module 7-6-2, rate adaptation module 7-6-3, multi-medium data buffer module 7-6-4.
Multi-medium data error correction mould 7-6-1, piece is mainly to carry out a kind of error correction for the mistake occurring in Multimedia Data Transmission process or error code, improves and repairs multi-medium data, reaches the accurate effect of multi-medium data;
Multi-medium data compensating module 7-6-2, mainly to compensate accordingly for some flaws that multi-medium data is existed, comprising frame losing compensation and resolution compensation etc. indemnifying measure, realize the integrality of multi-medium data, improve the excellent service standard of multi-medium data;
Rate adaptation module 7-6-3, mainly according to network speed and bandwidth resources in the residing mobile network environment of mobile device, adjust multimedia data transmission speed, by Rate Control and frame per second control device realize network speed and bandwidth resources can with the object of multimedia transmission rate best-fit, reduce that multi-medium data is lost or the situation of error code;
Multi-medium data buffer module 7-6-4, is mainly that multi-medium data is carried out to buffer-stored, is used for coordinating transfer rate and the network speed of multi-medium data, carries out dynamic buffering and adjustment.
As shown in Figure 6, the multimedia application process of mobile terminal device is:
(1) send multimedia application request
