20090097566 | MACROBLOCK PAIR CODING FOR SYSTEMS THAT SUPPORT PROGRESSIVE AND INTERLACED DATA - A method of performing block matching on a video image of progressive data includes: receiving the video image; storing the video image to a first storage; loading a current macroblock pair and a current search window of the video image to a second storage and utilizing the current search window to perform block matching for the current macroblock pair; and loading a next macroblock pair and a plurality of macroblocks corresponding to a non-overlapped area of a next search window to the second storage to perform block matching for the next macroblock pair. | 04-16-2009 |
20110293004 | METHOD FOR PROCESSING MOTION PARTITIONS IN TREE-BASED MOTION COMPENSATION AND RELATED BINARIZATION PROCESSING CIRCUIT THEREOF - A method for processing a target motion partition in a tree-based motion compensation includes utilizing a setting unit for providing a first binarization rule which defines a plurality of binarization codewords mapped to a plurality of syntax elements for different motion partitions, respectively, wherein a codeword length of a binarization codeword corresponding to any square inter-prediction motion partition is shorter than a codeword length of a binarization codeword corresponding to any non-square inter-prediction motion partition; and identifying mapping between a target binarization codeword and a target syntax element of the target motion partition according to the first binarization rule. | 12-01-2011 |
20130208804 | Method and Apparatus for Parsing Error Robustness of Temporal Motion Vector Prediction - A method and apparatus for deriving a motion vector predictor (MVP) are disclosed. The MVP is selected from spatial MVP and temporal MVP candidates. The method uses a flag to indicate whether temporal MVP candidates are disabled. If the flag indicates that the temporal MVP candidates are disabled, the MVP is derived from the spatial MVP candidates only. Otherwise, the MVP is derived from the spatial and temporal MVP candidates. The method may further skip spatial redundant MVP removal by comparing MV values. Furthermore, the parsing error robustness scheme determines a forced temporal MVP when a temporal MVP is not available and the temporal MVP candidates are allowed as indicated by the flag. The flag may be incorporated in sequence, picture, slice level, or a combination of these levels. | 08-15-2013 |
20130259118 | Method and Apparatus for Improved In-Loop Filtering - Methods and apparatuses for video decoding and encoding with in-loop processing of reconstructed video are disclosed. At the decoder side, the method comprises receiving a flag from the video bitstream and according to the flag, the method receives information associated with in-loop filter parameters either from a data payload in the video bitstream to be shared by two or more coding blocks or individual coding block data in the video bitstream. At the encoder side, the method comprises incorporating information associated with the in-loop filter parameters either in a data payload in a video bitstream to be shared by two or more coding blocks or interleaved with individual coding block data in the video bitstream according to a flag. The data payload in the video bitstream is in a picture level, Adaptation Parameter Set (APS), or a slice header. | 10-03-2013 |
20140269913 | METHOD AND APPARATUS FOR LOOP FILTERING - A method and apparatus for loop processing of reconstructed video in an encoder system are disclosed. The loop processing comprises an in-loop filter and one or more adaptive filters. The filter parameters for the adaptive filter are derived from the pre-in-loop video data so that the adaptive filter processing can be applied to the in-loop processed video data without the need of waiting for completion of the in-loop filter processing for a picture or an image unit. In another embodiment, two adaptive filters derive their respective adaptive filter parameters based on the same pre-in-loop video data. In yet another embodiment, a moving window is used for image-unit-based coding system incorporating in-loop filter and one or more adaptive filters. The in-loop filter and the adaptive filter are applied to a moving window of pre-in-loop video data comprising one or more sub-regions from corresponding one or more image units. | 09-18-2014 |
20150222912 | METHOD AND APPARATUS OF INTERLAYER TEXTURE PREDICTION - A method and apparatus for coding video data in a scalable or three-dimensional video coding system are disclosed. In one embodiment, context for the input data associated with an inter-layer or inter-view coding syntax element of a current block in an enhancement-layer (EL) or a dependent view is formed or the input data is parsed to identify the context based on information associated with one or more neighboring blocks, information associated with the current block, or both. In another embodiment, encoding or decoding is applied to the input data associated with the current block in the EL using inter-layer texture prediction based on the BL block in the BL, wherein a flag indicating whether there is any transform coefficient coded for the current block is signaled. | 08-06-2015 |
20150296211 | INTER-LAYER TEXTURE CODING WITH ADAPTIVE TRANSFORM AND MULTIPLE INTER-LAYER MOTION CANDIDATES - Methods of adaptive transform type based on transform unit (TU) size for enhancement layer (EL) coding and multiple motion candidates for EL coding based on corresponding base layer (BL) video data are provided. One method selects a transform type from multiple allowable transform types based on the TU size and applies the selected transform type to the transform units of the inter-layer prediction processed data. Another method derives multiple motion candidates for the EL video data coded in Merge mode or Inter mode based on motion information associated with the corresponding BL video data. | 10-15-2015 |
