Abstract
Video encoding (such as H.263, MPEG-4, H.264/AVC) modifies TMN5-type rate control frame skipping and quantization parameter updating according to buffer fullness levels with I-frame initial quantization parameter values depend upon quantization parameter value of prior P-frames but also has within I-frame prediction and parameter increase to avoid excessive bits. And variable input frame rate is accommodated by adjusting buffer fullness measures. The quantization also applies to image compression.
