Optimal Requantization-Based Rate Adaptation for H.264
Bit rate adaptation is one of the most important types of video transcoding. With H.264 becoming the predominant video codec of choice in video coding and streaming, prudent ratea...

Rate Control of H.264 Encoded Sequences by Dropping Frames in the Compressed Domain
A new technique for controlling the bitrate of H.264 encoded sequences is presented. Bitrate control is achieved by dropping frames directly in the compressed domain. The dropped f...

A lagrangian optimized rate control algorithm for the H.264/AVC encoder
The H.264/AVC video coding standard has been recently proposed by the Joint Video Team of ITU-T and MPEG experts. The AVC encoder achieves video bitstreams at the same quality as ...
