A Bandwidth Characterization Tool For MPEG-2 File

This paper proposes the design and development of Moving Picture Experts Group-2 (MPEG-2) Video Decoder to offer flexible and effective utilization of bandwidth services. The decoder is capable of decoding the MPEG-2 bit stream on a single host machine. The present decoder is designed to be simple, but yet effectively reconstruct the video from MPEG-2 bit stream. The designed MPEG-2 video decoder will display the name of each frame and corresponding frame bandwidth and also displays the buffer fullness for each picture, bit rate, time interval, maximum quantization error and decoded size of the pervious picture etc,. In order to characterize the bandwidth requirement, the proposed multimedia tool is tested on various MPEG-2 bit streams for the operation of effectiveness in terms of various performance parameters such as: cumulative bandwidth, peak bandwidth, average bandwidth and minimum bandwidth.
