摘要： An apparatus or method of efficiently coding high resolution video using texture analysis and synthesis techniques in a scalable video coding framework. A high-resolution video signal is spatially downsampled and encoded into a base-layer. Texture and structure information are extracted from the downsampled signal and base-layer for use by a texture synthesizer. The texture synthesizer is structurally and texturally aware utilizing edge information from a base-layer of the synthesizer to improve synthesis. After synthesis, a video quality assessor directs enhancement- layer coding of unacceptably synthesized areas by alternate (non-textural) coding means, such as conventional AVC or MPEG-2 coding. In one mode, the quality assessor iteratively improves synthesis of certain blocks to make them acceptable for enhancement-layer coding. The apparatus or method outputs a bit stream, or bit streams, containing both the coded base-layer and the enhancement-layer.

摘要： A codec extends the AVC standard in order to provide support for coding high resolution still image pictures within the AVC coding of a lower resolution video. The codec is capable of capturing an AVC video stream while concurrently capturing high resolution still images at random intervals relative to the video stream. Each captured high resolution still image is embedded within the video stream as a single layer bit stream. Each embedded high resolution still image signals or forces the start of a new GOP in the coded video sequence. The AVC standard is extended to include new syntax for the sequence parameter sets. In one embodiment, a modified sequence parameter set defines a new profile that signals the presence of a high resolution still image in sequence with AVC video.

摘要： A codec configured to operate in a parallel mode extends the current AVC standard in order to provide support for coding and storage of high resolution still image pictures in parallel with the AVC coding of a lower resolution video. The parallel mode codec is configured according to the modified AVC standard and is capable of capturing an AVC video stream while concurrently capturing high resolution still images at random intervals of the video stream. Residual information stored as an enhancement layer, is used to generate one or more high resolution still images pictures using the up-sampled decoded lower resolution video at the decoder side. A base layer carries lower resolution video. The enhancement layer and the base layer are transmitted in parallel, as a multi-layer stream, from an encoder on the transmission side to a decoder at the receiving side. To carry enhancement information, the AVC standard is extended to include data field(s) for SEI Message Definitions, sequence parameter sets, and a new NAL Unit.

摘要： A hybrid imaging device is configured to capture low resolution video and high resolution still images. The imaging device is configured to apply motion information obtained from the low resolution video to a reference high resolution still image to generate a missing moment of interest high resolution still image. The low-resolution video is captured at a high frame rate in conjunction with a few high-resolution still pictures taken at periodic intervals. A user locates a desired scene of interest, e.g. a moment of interest, from the captured video, and a post-processing technique is used to generate the high resolution still picture corresponding to the selected moment of interest. The high resolution still image is generated using texture information from one or more nearby captured high resolution still images and motion information from the low-resolution video frame corresponding to the selected moment of interest.

摘要： The currently existing ISO/ A VC file format is modified by providing extensions to store and access video content currently being defined by the SVC standard. Specifically, extensions to the AVC file format are made to provide a new SVC file format that enables the storage (88) and access of scalable video data. The scalable video data is stored as a single track within a media data section of the SVC file format. New extensions are defined for description entries and boxes within a metadata section of the SVC file format. These extensions provide means for extracting sub-streams or layers from the single track of scalable video data (22) stored in the media data section.

摘要： Implementations generally relate to data-charge phase data compression. In one implementation, a method includes computing prediction values for image data, where the image data is data-charge phase data, where the computing of prediction values is based on inter-block prediction, and where an additional bit-budget is assigned to a first block of the image data. The method also includes computing residual data based on the prediction values. The method also includes quantizing the residual data. The method also includes entropy encoding the quantized residual data. The method also includes refining an inverse quantized residual data based on one or more of the residual data and a number of left-over bit-budget after entropy encoding.

摘要： High efficiency video coding (HEVC) enhancements are described for intra-block copying for reducing motion vector (MV) coding redundancy and enhancing in range extensions (RExt) by selecting a default block mv predictor. In reducing MV data redundancy, the value of MVx and/or MVy can have a baseline at the width (W), or height (H) of the respective block, whereby fewer bits need to be encoded. One embodiment for enhancing RExt provides an improved selection of a default block vector predictor for the first CU performing intra-block copying in a CTU.
