摘要： In one embodiment, the method includes determining a motion vector of a current image block equal to a motion vector of an image block based on a reference picture index indicating a reference picture for the image block. For example, the motion vector of the current image block may be equal to the motion vector of the image block if the reference picture index indicates a long-term reference picture for the image block.

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： 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： A broadcast system provides support for clients to receive transmissions over a unicast or a multicast channel from a broadcast server. A server administrator configures each of a first server and client systems connected to the server to receive data in one of a multicast or unicast transmission mode. An empirical test determines whether an intervening network can support the configured mode and if not, transmission is performed using a fall back mode. The first server is able to provide access to data streams from other servers to the client systems connected thereto. Upon requesting a data stream from another server, the first server receives the data stream, replicates the data stream, transmits the data stream to the requesting client system and stores the replicated data stream for immediate access by any requesting client server connected thereto.

摘要： In the motion estimation and compensation process for video frames, blocks O of pixels are considered. A number k of bit planes in a block O in a video frame F are compared with blocks OR in reference frames (FR). The best matching block (ORM) is determined in the reference frames (FR). Subsequently, a weight value (Wxij) is calculated for the best matching block (ORM) based on the ratio of valid pixels therein. The residual pixel values (Vxij) extracted from the best matching block (ORM) and corresponding weight values (Wxij) are stored in a pixel prediction array (120). The pixel array is used for motion compensation of at least the luminance component of valid pixels. Invalid pixels are reconstructed from surrounding pixel values.
