Abstract


Support , including sports , including a moving image due to the highest image resolution , that are supported by the MPEG-2 , which makes a very wide range in the practical application . In this paper, the analysis of the MPEG-2 Systems , pointed out that the system prone to lack of video material by cutting and positioning difficulties involved in television production , the editing of video files and video stream decoding , to solve the problem . This paper was the realization of a single-file and multi-file editor , software design , debug , and compare the existing system performance . The results show that the stable operation of the software system designed in this paper , audio and video synchronization , control the audio decoder and video decoder system clock performance than existing systems have greatly improves , stable and reliable work . In this paper, the following aspects : 1 . Applications MPEG-2 hardware and software video files to play . The Optibase The VideoPlex series using playback cards on the two clips for seamless playback , and function provided by encapsulating the Optibase playback card SDK secondary development . 2.MPEG-2 file editing and decoder combined with the characteristics of Windows programming , and object-oriented programming , defines several structure and class writing editing software for editing video files , define the the structure Layer_data structure data on MPEG-2 video stream decoding .3 system debugging synchronization of audio and video , seamless connection of multi - material the decoded images show three tasks . The results of the system to achieve its function , stable work . The benefits of the MPEG-2 standard is reflected in its adaptability . Can be designed to meet the standards of the range of application needs . Embodied in their features have two characteristics, a motion compensation brought high compression ratio , the other is done by adjusting the parameters of the bit-rate variable according to different needs .
