摘要： A method and a signal processor for receiving a data stream comprising at least two distinct sets of encoded data, at least one set of which is relative to transient/stochastic components of a signal. Based at least in part on the distinct sets of encoded data, the signal processor decodes and reconstructs a corresponding rendition of signal for each set of the encoded data. The distinct sets of renditions of signal are then combined into a single rendition of reconstructed signal.

摘要： Computer processor hardware receives settings information for a first image. The first image includes a set of multiple display elements. The computer processor hardware receives motion compensation information for a given display element in a second image to be created based at least in part on the first image. The motion compensation information indicates a coordinate location within a particular display element in the first image to which the given display element pertains. The computer processor hardware utilizes the coordinate location as a basis from which to select a grouping of multiple display elements in the first image. The computer processor hardware then generates a setting for the given display element in the second image based on settings of the multiple display elements in the grouping.

摘要： Computer processor hardware receives a first set of adjustment values. The first set of adjustment values specify adjustments to be made to a predicted rendition of a signal generated at a first level of quality to reconstruct a rendition of the signal at the first level of quality. The computer processor hardware processes the first set of adjustment values and derives a second set of adjustment values based on the first set of adjustment values and a rendition of the signal at a second level of quality. The second level of quality is lower than the first level of quality.

摘要： Certain configurations herein include changing the resolution of an auxiliary map (e.g., a motion map, a z-map, etc.) at a first level of quality to obtain an auxiliary map at a second level of quality. For example, changing the resolution can include receiving a respective auxiliary map of one or more vectors at one or more lower levels of quality and progressively refining, via novel operations, the auxiliary map to higher or lower levels of quality in a hierarchy.

摘要： Computer processor hardware receives zone information specifying multiple elements of a rendition of a signal belonging to a zone. The computer processor hardware also receives motion information associated with the zone. The motion information can be encoded to indicate to which corresponding element in a reference signal each of the multiple elements in the zone pertains. For each respective element in the zone as specified by the zone information, the computer processor hardware utilizes the motion information to derive a corresponding location value in the reference signal; the corresponding location value indicates a location in the reference signal to which the respective element pertains.

摘要： A data processor retrieves reconstruction data and corresponding stream metadata from a repository, the reconstruction data encoded in accordance with a tiered hierarchy including multiple levels of quality. The data processor transmits selected portions of the reconstruction data to one or more decoder resources. The decoder resources reconstruct renditions of portions of a signal such as images/frames based on the transmitted portions of reconstruction data. During the transmission step, the data processor may vary a level of quality of the reconstruction data retrieved and transmitted to the decoder resource to play the signal at different levels of quality. Also, at times, the data processor may transmit the levels of quality of the reconstruction data out of the natural sequence of the portions of the signal that they allow to reconstruct, anticipating or postponing the transmission of certain levels of quality of reconstruction data related to specific portions of the signal.

摘要： A signal processor receives settings information. The settings information specifies a setting of a given element for each image in a sequence of multiple images in which the given element resides. The signal processor also receives precision metadata specifying an estimated precision of each of the settings of the given element for each image in the sequence. Based on the settings information and the precision metadata, the signal processor generates a setting value for the given element. If the setting value produced for the given element is relatively stable, and thus likely a better representation of a setting for the given element than a current setting of the given element, the signal processor utilizes the generated setting value instead of the current setting for encoding purposes.
