A constant-quality, single-pass VBR control for DVD recorders

This paper describes a low complexity variable bit-rate (VBR) control method that achieves excellent and constant visual quality for single-pass, real time MPEG-2 encoding in DVD recorders. The bit-rate is controlled in a very accurate way. The algorithm runs in software on a very long instruction word (VLIW) processor by using less than 3 Millions of clock cycles.
