摘要： A battery operated device, having a display with two or more available refresh rates, has its refresh rate selected so as to match the video frame rate of video data played back on the display. This selection is made by coordinating the resources in the device that are used to process the video from its reception through to its display.

摘要： Systems and methods for smooth rewind playback of streamed media are provided. The media includes relatively-encoded frames and independently-encoded frames. The method includes receiving a rewind request indicating a rewind speed for rewind playback of the media, selectively dropping relatively-encoded frame(s) based on a receipt constraint and a decoding constraint to form a subset of the media, and receiving frames of the subset. The method further includes selecting, in a reverse order, a selected group of pictures (GOP) included within the subset, and decoding relatively-encoded frame(s) of the GOP in a forward sequential frame order. The method further includes caching relatively-encoded frame(s) of the GOP in the forward sequential frame order, and when caching, dropping and overwriting relatively-encoded frame(s) of the GOP selectively according to a memory constraint and/or a display constraint. The method further includes displaying relatively-encoded frame(s) of the GOP in a reverse sequential frame order.

摘要： A video bit stream with pictures comprising inter-coded content can be decoded upon receiving a channel start or file seek instruction. Pictures for beginning decoding and display of the bit stream can be selected based at least in part on one or more tuning parameters that set a preference between a latency of beginning to display video and possible defects in the displayed video. In some embodiments, to implement decoding upon a channel start or file seek, one or more types of data are generated for one or more pictures. For example, picture order counts are generated for pictures after a channel start or file seek operation. As another example, a decoder generates a frame number value that triggers re-initialization of a reference picture buffer before decoding after a channel start or file seek operation.

摘要： A method, system, computer program product, and computer system for processing video frames. Frames A and B of a pair of successive video frames each comprise blocks of pixels. Frame A is earlier in time than frame B. A connection state of each pixel in frame B relative to the pixels of frame A is determined. The connection state is a connected state or an unconnected state. Each block in frame B is classified as either unconnected or uni-connected. Uni-connected blocks in frame B satisfying a reclassification criteria are reclassified as being unconnected. Each unconnected block in frame B is categorized as being a P-block or an I-block. Values for the pixels of each I-block in frame B are calculated by spatial interpolation based on values of nearest available neighbor pixels relative to each I-block. A residual error block for each I-block in frame B is generated.

摘要： A decoder which can detect errors in MPEG-2 coefficient blocks can identify syntactically-correct blocks which have out-of-bounds coefficients. The decoder computes coefficient bounds based on quantization scalers and quantization matrices and compares these to coefficient blocks during decoding; if a block has out-of-bounds coefficients, concealment is performed on the block. In a decoder implemented all in software, coefficient bounds checking is performed on iDCT coefficients against upper and lower bounds in a spatial domain. In a decoder which performs iDCT in hardware, DCT coefficients are compared to an upper energy bound.

摘要： Techniques and tools for interpolation of image/video content are described. For example, a tool such as a display processing module in a computing device receives pixel values of a low-resolution picture and determines an interpolated pixel value between a set of the pixel values from the low-resolution picture. The tool uses auto-regressive edge-directed interpolation that incorporates a backward projection constraint (AR-EDIBC). As part of the AR-EDIBC, the tool can compute auto-regressive (AR) coefficients then apply the AR coefficients to the set of pixel values to determine the interpolated pixel value. For the backward projection constraint, the tool accounts for effects of projecting interpolated pixel values back to the pixel values of the low-resolution picture. The tool stores the interpolated pixel values and pixel values from the low-resolution picture as part of a high-resolution picture. The tool can adaptively use AR-EDIBC depending on content and other factors.

摘要： In various respects, hardware-accelerated decoding is adapted for decoding of video that has been encoded using scalable video coding. For example, for a given picture to be decoded, a host decoder determines whether a corresponding base picture will be stored for use as a reference picture. If so, the host decoder directs decoding with an accelerator such that the some of the same decoding operations can be used for the given picture and the reference base picture. Or, as another example, the host decoder groups encoded data associated with a given layer representation in buffers. The host decoder provides the encoded data for the layer to the accelerator. The host decoder repeats the process layer-after-layer in the order that layers appear in the bitstream, according to a defined call pattern for an acceleration interface, which helps the accelerator determine the layers with which buffers are associated.
