    摘要: Floating point video coding is described. In particular, a video encoder/decoder and methods for floating point video coding are discussed. Floating point video coding can be used in the video encoder and decoder to support video content, such as HDR content. Specifically, a video codec structure such as H.264/AVC can be modified in order to support floating point video coding. Within any component of a codec system, some operations can be performed at floating point precision whereas other operations can be performed at fixed point precision.

    摘要: Reference processing may be used in a video encoder or decoder to derive reference pictures that are better correlated with a source image to be encoded or decoded, which generally yields better coding efficiency. Methods for filter selection for a reference processing unit adapted for use in a video codec system are discussed. Specifically, methods for filter selection based on performing motion estimation and obtaining distortion/cost information by comparing reference pictures, either processed or non-processed, with the source image to be encoded are discussed.

    摘要: A buffer is established in a video encoder and/or a video decoder. An adaptive filter is buffered in the established buffer. An input video signal is coded using the buffered filter. The filter buffer may be managed, e.g., as to buffer size or capacity, filter placement within the buffer, and buffered default filters. Adaptive filters may be signaled and buffered for multiple reference pictures.
