Towards a Comprehensive RVC VTL: A CAL Description of an Efficient AVC Baseline Encoder
The Video Tool Library (VTL) is one of the major normative components of the Reconfigurable Video Coding (RVC) standard. It specifies the set of functional units (FUs)that may be interchangeably combined and connected to form different video codecs, with various compression performances and implementation complexities. In this paper, an efficient AVC baseline encoder that is described in CAL is introduced. The encoder is composed of many modules that also exist in other codecs of the same or different standards. This makes them highly reusable within the RVC framework. The main modules of the designed encoder include: Inter Prediction, Intra Prediction, and Entropy Coding. Brief descriptions of the designed modules, accompanied with CAL design issues are provided.
