摘要:
Processing a reference picture is described. A reference processing unit enables signaling of parameters such as motion model parameters, interpolation filter parameters, intensity compensation parameters, and denoising filter parameters. Methods for estimating the various parameters are also discussed. Processing improves quality of a reference picture prior to its use for prediction of a subsequent picture and thus improves the prediction.

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:
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.

Adaptive decoding and streaming multi-layer video systems and methods are described. The decoding systems comprise a base layer decoder and one or more enhancement layer decoders. The streaming systems comprise a base layer packetizer and one or more enhancement layer packetizers. A decoding adaptor controls operation of the base layer and/or enhancement layer decoders. A packetizing adaptor controls operation of the base layer and/or enhancement layer packetizers.
摘要:
Encoding and decoding methods for single and multiple layered video coding systems are provided. Specifically, video information provided to a base layer and one or more enhancement layers can be coded using a picture coding mode and/or a residual coding mode. Selection between coding modes can be performed on a region-by-region basis.

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.
