Video Coding
MPEG-1 permits resolutions up to 4095×4095 at 60 frames per second (progressive scan). What many people think of as MPEG-1 is a subset known as Constrained Parameters Bitstream (CPB). The CPB is a limited set of sampling and bit-rate parameters designed to standardize buffer sizes and memory bandwidths, allowing a nominal guarantee of interoperability for decoders and encoders, while still addressing the widest possible range of applications. Devices not capable of handling these are not considered to be true MPEG-1. Table 7.1 lists some of the constrained parameters. Table 7.2 list some of the more common MPEG-1 resolutions.
