ABSTRACT:
A profile of information flow rate of a source data stream having inherently variable information flow rate may be developed and conformed to a constrained target profile of output bit rate as would be generated by a variable compression ratio encoding scheme to be applied to the source data stream. The target profile may be constrained as to minimum output bit rate, maximum output bit rate, and average output bit rate. The resulting conforming profile identifies an encoding plan for the source data stream. One application is preparation of video material for storage on a DVD (Digital Versatile Disc) where total bit storage capacity is limited, the source data stream is an uncompressed video data stream, and the target encoding scheme is MPEG-2 data compression.
