摘要： Filter taps for filters are specified by filter coefficient parameters. The filter taps are greater in number than the coefficient parameters from which the filter taps are calculated. For example, two coefficient parameters are used to specify a four-tap filter. Filter information can be signaled in a bitstream, such as by signaling one or more family parameters for a filter family and, for each filter in a family, signaling one or more filter tap parameters from which filter taps can be derived. Family parameters can include a number of filters parameter, a resolution parameter, a scaling bits parameter, and/or a full integer position filter present parameter that indicates whether or not the filters include an integer position filter. Filter parameters can be signaled and used to determine coefficient parameters from which filter taps are calculated.

摘要： A system identifies video data to be encoded as well as multiple display regions associated with a particular video display type. Each of the multiple display regions is associated with a different portion of an image associated with the video data. The video data is encoded such that the encoded video data includes information regarding the multiple display regions. Each of the multiple display regions has an associated display region identifier. Additionally, the system may identify an active region of the video data. The active region may be located anywhere within an image associated with the video data. The video data is encoded such that the encoded video data includes information regarding the active region.

摘要： Techniques and tools for high accuracy position calculation for picture resizing in applications such as spatially-scalable video coding and decoding are described. In one aspect, resampling of a video picture is performed according to a resampling scale factor. The resampling comprises computation of a sample value at a position i,j in a resampled array. The computation includes computing a derived horizontal or vertical sub-sample position x or y in a manner that involves approximating a value in part by multiplying a 2n value by an inverse (approximate or exact) of the upsampling scale factor. The approximating can be a rounding or some other kind of approximating, such as a ceiling or floor function that approximates to a nearby integer. The sample value is interpolated using a filter.

摘要： Timecoding systems, methods and data structures are described which, in some embodiments, permit a true time to be ascertained from media samples whose timecodes contain an amount of drift which can arise from having non-integer frame rates. Inventive methods incorporate the use of an offset parameter that describes a time difference between a timecode and a true time associated with a media sample. The inventive approaches can be incorporated with and used compatibly in connection with current timecoding paradigms such as SMPTE timecode and the like. Further embodiments permit timecoding to take place at the field level of a frame. This can permit true-time calculations to be done to ascertain the true time associated with individual fields of a frame. In addition, other embodiments provide novel counting compensation methods that are directed to reducing the drift that can be associated with media samples that are sampled at non-integer frame rates.

摘要： Innovations in intra block copy (“BC”) prediction mode facilitate intra BC prediction that is more effective in terms of rate-distortion performance and/or computational efficiency of encoding and decoding. For example, some of the innovations provide ways to select block vector (“BV”) values more effectively. Other innovations provide ways to encode/decode BV values more efficiently. Still other innovations address how to perform in-loop deblock filtering when a block has intra BC prediction mode, or address how to perform intra BC prediction when constrained intra prediction is enabled.

摘要： A first frame of data is encoded and a first timestamp associated with the first frame of data is generated. The first timestamp includes complete timing information. The first frame of data and the associated first timestamp is transmitted to a destination. A second frame of data is encoded and a second timestamp associated with the second frame of data is generated. The second timestamp includes a portion of the complete timing information. The second frame of data and the associated second timestamp is then transmitted to the destination. Additional frames of data are encoded and additional timestamps associated with the additional frames of data are generated. The majority of the additional timestamps include a portion of the complete timing information.
