Perceptual Quality Based Rate Control Method for AVC-Intra
Madan Mohan · 2013
AVC-Intra specification is aimed at high quality and high definition broadcast products. The AVC - Intra specification specifies compression constraints and bit stream syntax on the High 10 Intra profile and the high 4:2:2 Intra profile. It has Class 100 and Class 50 mode, which demands very accurate rate control algorithm since each intra frame has to be encoded at exact same number of coded bytes per frame as specified in SMPTE RP 2027-2007. Need for very good perceptual quality and also accurate bit-rate control exist in application using this profile, which requires perceptual quality based rate control algorithm method with accurate bit-rate control. The paper discusses about perceptual quality based rate control method in AVC -Intra, which could be easily extended for other video coding methods as well.
