This subsection describes functions for encoding of digital audio-video in accordance with the AVS ([AVS]) standard.
Other general functions used by the AVS Encoder for predicted blocks estimation and for obtaining residual blocks are SAD Functions, Sum of Differences Evaluation functions, and GetDiff8x8 function.
The AVS Encoder uses the AVS Decoder functions for calculation of inter and intra predicted blocks, Macroblock Reconstruction, and Deblocking Filtering. Forward transform and quantization, and CAVLC coding are performed by Encoder proper functions, which are described below.
