Abstract
A method and concomitant apparatus for adapting the behavior of an MPEG-like encoder to information discontinuities within a received information stream, such that encoding quality and random access to a resulting encoded stream is retained near information discontinuity point without adversely impacting buffer utilization parameters. Specifically, an anchor frame comprising an I-frame preceding an information discontinuity is encoded as a P-frame, while an anchor frame following the information discontinuity is encoded as an I-frame.
