摘要： An Encoder Assisted Frame Rate Up Conversion (EA-FRUC) system that utilizes video coding and pre-processing operations at the video encoder to exploit the FRUC processing that will occur in the decoder in order to improve compression efficiency and reconstructed video quality is disclosed. One operation of the EA-FRUC system involves determining whether to encode a frame in a sequence of frames of a video content by determining a spatial activity in a frame of the sequence of frames; determining a temporal activity in the frame; determining a spatio-temporal activity in the frame based on the determined spatial activity and the determined temporal activity; determining a level of a redundancy in the source frame based on at least one of the determined spatial activity, the determined temporal activity, and the determined spatio-temporal activity; and, encoding the non-redundant information in the frame if the determined redundancy is within predetermined thresholds.

摘要： With use of a simplified program or calculating device for motion compensation, a video decoding device decodes video data compressed by motion detection operations on macroblock units, as in the MPEG-4AVC standard. The video decoding device splits compressed data blocks of the prescribed size, 16×16 pixels for instance, to generate sub-blocks, which are smaller than the blocks and on which the video decoding device is able to execute motion compensation operations. The video decoding device duplicates a motion vector assigned to a given block to generate as many motion vectors as there are sub-blocks in the given block, and executes motion compensation on each sub-block using the corresponding duplicate motion vector. Data resulting from the motion compensation operation on each sub-block is combined to obtain a target block corresponding to the given block.

摘要： A fade state determination unit (5) determines that the target picture is in a fade state when a feature value A is equal to or larger than a threshold value TH_A. If the target picture has been determined to be in the fade state, a fade-in determination unit (6) determines that the target picture is of a fade-in type when a feature value B is equal to or larger than a threshold value TH_B1 and a feature value C is less than a threshold value TH_C. If the target picture has been determined to be in the fade state, a fade-out determination unit (7) determines that the target picture is of a fade-out type when the feature value B is less than a threshold value TH_B2 that is smaller than the threshold value TH_B1. A cross-fade determination unit (8) determines that the target picture is of a cross-fade type when the target picture has been determined to be in the fade state and be not of the fade-in type nor of the fade-out type.

摘要： The present invention relates to a method for inducing a merge candidate block and a device using same. An image decoding method involves decoding motion estimation region (MER) related information; determining whether or not a predicted target block and a spatial merge candidate block are included in the same MER; and determining the spatial merge candidate block to be an unavailable merge candidate block when the predicted target block and the spatial merge candidate block are included in the same MER. Accordingly, by parallely performing the method for inducing a merge candidate, parallel processing is enabled and the computation amount and implementation complexity are reduced.

摘要： A system (and a method) are disclosed for intelligently fetch one or multiple reference blocks from memory for each block to be motion compensated or motion estimated within a video processing system. The system includes a reference block configuration evaluation unit and a motion compensation memory fetching unit. The reference block configuration evaluation unit analyzes the reference block configuration of the block being motion compensated with a plurality of reference block configurations of its neighboring blocks. In response to a reference block configuration evaluation result, the reference block configuration evaluation unit decides the configuration of reference blocks to be fetched from a memory. The motion vector memory fetching unit fetches the number of reference blocks for motion compensation accordingly.
