Patent abstract
A Flexible Band Offset (FBO) apparatus and method of performing Sample Adaptive Offset (SAO) filtering within encoders and decoders, such as according to the High Efficiency Video Coding (HEVC) standard, and similarly configured coding devices. The number of Band Offset (BO) modes and the number of necessary offsets is reduced. The invention beneficially provides simpler coding, reduces temporary buffer size requirements, and can yield a small performance gain over existing SAO techniques of HEVC test model HM 5.
