Abstract

This contribution will examine the parallel characteristics of MPEG video encoding and explore the feasibility of using a group of workstations under a LAN to perform MPEG-II encoding. An analysis of partitioning the MPEG algorithm into several tasks is presented. This is followed by the details of implementation by using socket programming as a means to coordinate the workstations. The following conclusions have been reached: (1) Since each slice header has a start code which is byte-aligned, each slice is a good basic unit for parallel processing. This is the case for I- P- and B-pictures. (2) All the most computationally expensive operations, such as Motion Estimation and DCT, can be conducted in parallel. (3) The quantization parameter is processed in a sequential manner since it should be derived from the history of the encoding. Computer simulations have been conducted, and the bitstreams generated are the same as those of a sequential encoder and can be decoded by an MPEG-II decoder.
