摘要： A motion vector prediction method in an error resilient mode. In the motion vector prediction method capable of decoding backwards, motion vectors of macro blocks are calculated, and motion vectors of macro blocks each having one motion vector are predicted while moving to another macro block from left to right, and motion vectors of macro blocks each having four motion vectors are continuously predicted in a predetermined sequence to have correlation in prediction of the four motion vectors. Thus, in the motion vector prediction method based on the image signal compression method of the MPEG-4 or H.263 standard, the motion vector prediction is performed with continuity and correlation among the motion vectors, so that two-way decoding is possible during transmission of blocks with a predetermined packet, resulting in better error resilient characteristics.

摘要： A video coding-decoding (CODEC) method in an error resilient mode, a computer readable medium having a computer program for the video CODEC method, and a video CODEC apparatus. The video CODEC method provides more resilience against channel error such that communications are less affected by error under conditions in which errors are a serious problem such as in a wireless communications channel. In the video CODEC method, a header data part (HDP) bit region, a motion vector data part (MVDP) bit region and a discrete cosine transform data part (DDP) bit regions are partitioned from each macro block of the video data in an error resilient mode, and then the partitioned bit regions are variable-length-coded. Then, the bit regions selected from the variable-length coded bit regions according to a predetermined priority for recovery are reversible-variable-length-coded, and markers are then inserted into the variable-length coded or reversible-variable-length-coded bit regions.

摘要： A method of representing encoding or non-encoding by extending a video information field of a block when coding video information, is provided. The method of representing encoding or non-encoding by extending an information field for representing encoding or non-encoding is applied to an error allowable mode. Also, the amount of bits depending on the characteristics of video information to be encoded can be reduced. In this method, an image is encoded by extending a code (COD) field which is used in H.263 and MPEG-4 to indicate the cases where neither a motion vector (MV) nor a discrete cosine transform (DCT) value are encoded, where both the MV and the DCT value are encoded, and where only the MV is encoded. Therefore, in a channel with errors, the extended OCD field can be used in the error allowable mode. Also, video information can be encoded using a smaller amount of bits where the motion of an image is constant, than in the conventional art.

摘要： In some embodiments, a video decoder is capable of recovering skipped video data (e.g. motion vectors, prediction modes, quantization parameters, selected frequency-domain coefficients such as DC and 5-lowest-frequency AC coefficients, and/or entire video data blocks) using multiple alternative recovery modes such as spatial interpolation, temporal interpolation, and motion search. To decide whether to skip a particular data type for a block, the encoder evaluates the effect of skipping the data on rate and distortion by simulating the decoder data recovery using the multiple recovery modes. The encoder transmits indicators of skipped data types and associated recovery modes, if different from decoder baselines. The skipped data and recovery mode indicators may be included in macroblock and/or slice headers, and/or as part of sequence, group-of-picture (GOP), or picture coding parameter data. Skipped data recovery decoder resources (e.g. motion search logic) may be used for recovering data lost due to transmission errors.

摘要： An image and video enhancement technique is described that allows a core enhancement algorithm to be applied to images captured in various challenging lighting conditions. The technique detects a lighting impairment and inverts the image if it is a low-light impairment. The inverted low-light image is similar to haze impairment images, allowing both haze images and low-light images to be enhanced using the same enhancement algorithm.

摘要： The present invention is a method and system which extracts, manipulates and embeds data from a compressed and standard compliant video bitstream which may be used for digital rights management, e.g. controlling access to a bitstream or for authenticating a video bitstream.The method embeds binary data bits into compressed and standard compliant video bitstream with minimal visual artifacts. The method first parses the compressed video bitstream and locates coded blocks. The codeword C for the last triplet in the original block(RUNc,LEVELc, LASTc=1) is replaced by the VLC code word C′ for the last triplet (RUNC,LEVELC, LASTC′=0). A codeword corresponding to a triplet with LAST=1 is placed after C′ whose sign bit “s” can be either 0 or 1 and is an embedded data bit, and can be used for authentication.
