The second phase of the ISO Moving Picture Experts Group audio-visual coding standard (MPEG-2) is nearly complete and this standard is expected to be used in a wide range of applications at variety of bitrates. While the standard specifies the syntax of the compressed bitstream and the semantics of the decoding process, it allows considerably flexibility in choice of encoding parameters and options enabling appropriate tradeoffs in performance versus complexity as might be suitable for an application. First, we present a review of profile and level structure in MPEG-2 which is the key for enabling use of coding tools in MPEG-2. Next, we include a brief review of tools for nonscalable coding within MPEG-2 standard. Finally, we investigate via simulations, tradeoffs in coding performance with choice of various parameters and options so that within the encoder complexity that can be afforded, encoder design with good performance tradeoffs can be accomplished. Simulations are performed on standard TV and HDTV resolution video of various formats and at many bitrates using nonscalable (single layer) video coding tools of the MPEG-2 standard.
