Apparatus and method for multimedia reproduction using output buffering in a mobile communication terminal

Abstract

A multimedia reproduction apparatus in a mobile communication terminal comprising: a data parsing section for dividing multimedia data into video data and other data and then parsing the video data and the other data; a video data processing section for decoding the parsed video data; a media delay output controller for delaying the other data parsed by and transmitted from the data parsing section according to buffering information of the video data processing section, for outputting the delayed data, and for generating a synchronizing signal; an audio data processing section for decoding and outputting audio data from among the other data output from the media delay output controller; a video data output section for reading and outputting the video data; and a synchronizing section for synchronizing and outputting the video data.

Description

technical field [0001] The invention relates to a multimedia reproduction device in a mobile communication terminal. Background technique [0002] In general, in the development toward a highly information-oriented society, information and communication are increasing in importance as social infrastructure, and the center of importance of communication services is shifting from traditional wired communication to wireless communication, which places importance on move. In addition, a new market called wireless Internet that unites the Internet and mobile communication is developing at a high speed. [0003] As mentioned above, with the huge increase of users' dependence on information and communication, and the improvement of wireless communication technology, the first generation analog system has become the second generation digital system, and now a third generation dedicated to data communication is being developed. Generation Mobile Communications (IMI-2000). [0004]...

AI Technical Summary

Problems solved by technology

However, when the part 302 processes the intra frame, since the output critical time is short, the intra frame is decoded beyond the critical time indicated by reference numeral 51, so that only audio output may be output without video

Also, synchronization between video and audio may fail, as indicated by reference numeral 52

[0017] As described above, in the case of reducing the waiting time by a method of reducing the output critical time to effectively utilize the limited resources of the mobile communication terminal, the quality of service (QOS), which is one of the most important factors in multimedia reproduction, cannot be satisfied. one
