摘要： A method of video decoding performed in a video decoder is disclosed. A syntax element can be received from a bitstream of a coded video that indicates whether a sequence of pictures are monochrome or include three color components that are coded separately. By inferring a value of a syntax element, a coding tool can be disabled when the syntax element indicates that the sequence of pictures are monochrome or include three color components that are coded separately. The coding tool uses multiple color components of a picture as input or depends on a chroma component of a picture. Examples of the disabled coding tools can include joint coding of chroma residuals, active color transform (ACT), or block-based delta pulse code modulation (BDPCM) for chroma component.

摘要： The system provides a method and apparatus for constructing, and for dynamically rearranging the order of content in a composite video. The re-ordering of clips in the composite video can be based on one or more weighting factors associated with each clip. These factors can include freshness or newness of the clip, popularity based on the number of "likes" of a clip by others, the content of the clip (e.g. celebrity creator or presence), paid boosting (e.g. for commercial concerns); and other factors. Each clip has associated metadata that can be used to assign a weight value to the clip for purposes of reordering the composite video.

摘要： A video coding/decoding system builds implied reference frames from a plurality of reference frames developed during coding. Coded data of reference pictures are decoded and stored in a reference picture cache. An implied reference frame may be derived from a plurality of reference frames and may be stored in the reference picture cache. Thereafter, coding of new input data may proceed using the implied reference frame as a source of prediction. The method may be used to identify visual elements such as background elements that may persist in video over a longer period that can be captured by the system under conventional reference frames assembly and eviction. Implied reference frames may be built at both an encoder and a decoder to serve as sources of prediction.

摘要： A picture (1) with multiple slices (2-5) is encoded by determining a hierarchical granularity for the picture (1) defining a hierarchical level for slice border alignments. Address information allowing identification for a respective slice start is determined for at least a portion of the slices (2-5) based on the hierarchical granularity. The pixel values of the slices are encoded to generate coded slice representations (56). These coded slice representations (56) are included together with the address information into a coded picture representation (50) to which information of the hierarchical granularity is associated. The hierarchical granularity provides a flexible way of defining at which coding unit level slice borders can be present in the picture (1).

摘要： A system and method may compress a digital image. A storage unit may store a dictionary having a plurality of predetermined template patterns each identified by a code. A decomposition module may divide the image into a plurality of sub-regions. A compression module may select a template pattern from the dictionary that most closely matches an image features for each sub-region. The compression module may generate a compressed data set for the image in which each sub-region is represented by a code identifying the template pattern selected therefore. Once the data is compressed, a decompression unit may reconstruct the image. The decompression unit may use the code from the compressed data set to retrieve the template pattern from the dictionary for each sub-region and may reconstruct a full image by combining the template patterns for all of the sub-regions. An output device may display the reconstructed image.

摘要： A system and method that provides a connection path between a video source such as a personal computer (PC) and a high- definition television (HDTV). A control is provided for varying a quality level of a video signal with respect to latency of activities provided through the video signal channel. Output picture quality versus latency is adjusted on a dynamic basis. Observed mouse activities causes the output picture quality to be decreased rapidly with an attendant decrease in latency. A decrease in output picture quality and latency is maintained until the occurrence of a particular event, such as the expiration of a time interval from a last observed mouse event. If a limited number of mouse events are observed, then the output picture quality is increased to a point at which the limited mouse activity can be accommodated with an acceptable level of latency. If limited or no mouse events are observed for a given period of time, the output picture quality is increased, either rapidly or gradually, until output picture quality is restored or another mouse event is observed.
