Abstract :
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 frames are carefully selected so as to either eliminate or cause non perceptible drift errors in the decoder. The technique suits well H.264 encoded sequences such as movies and tv news, which are transmitted over wireless networks.
