Abstract: Examples described herein relate to decoding and encoding signals. A method of performing signal decoding operations on one or more portions of a signal is presented. The performing is based at least in part on information embedded in one or more values received in one or more encoded data layers transmitted within a stream of encoded data, wherein said values are associated with transformed coefficients intended to be processed by a decoder for deriving elements of the signal, and wherein said information comprises an indication of watermarking information associated with the signal.

Abstract: There is disclosed a method of encoding an input signal, the method comprising: receiving a base encoded signal, the base encoded signal being generated by feeding an encoder with a down-sampled version of an input signal; producing a first residual signal by: decoding the base encoded signal to produce a first decoded signal; and using a difference between the base decoded signal and the down-sampled version of the input signal to produce the first residual signal; producing a second residual signal by: correcting the base decoded signal using the residual signal to create a corrected decoded version; up-sampling the corrected decoded version; and using a difference between the up-sampled corrected decoded signal and the input signal to produce the second residual signal; wherein the up-sampling is one of bilinear or bicubic up-sampling. A corresponding decoding method is also disclosed.

Abstract: There is provided a method for processing an input signal (700). The input signal (700) is processed at least by converting the input signal (700) from a first colour space to a second colour space, to produce a first processed signal. The processed signal is encoded by a first encoding module (703) to generate a first encoded signal (710). A decoded signal is generated by decoding the first encoded signal (710). The decoded signal is processed at least by converting the decoded signal from the second colour space to the first colour space to produce a second processed signal. The second processed signal and the input signal (700) are processed by a second encoding module (707) to generate a second encoded signal (720).

Abstract: There is provided a method for encoding and decoding a signal. The method comprises receiving a first signal (900) and a second signal (960), the first and second signals comprising different versions of a common content, the first signal (900) using a first signal element coding format and the second signal (960) using a second signal element coding format. The first signal (900) is encoded by a lower encoding module (1103) to generate a lower encoded signal (910). The lower encoded signal (910) is decoded to generate a lower decoded signal. The lower decoded signal is processed by at least converting from the first signal element coding format to the second signal element coding format and up-sampling, to produce a processed signal. The processed signal and the second signal (960) are processed by an upper encoding module (1107) to generate an upper encoded signal (920).

Abstract: 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.

Abstract: 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.

Abstract: Techniques for encoding a signal are described. A signal is down-sampled to generate a version of the signal. This version of the signal is then encoded to produce a first encoded signal. The first encoded signal is then decoded to produce a first decoded signal. The second decoded signal is up-sampled to obtain a first up-sampled decoded signal. A first residual signal is obtained by taking a difference between the first up-sampled decoded signal and a first reference signal. The first reference signal corresponds to the signal prior to down-sampling. The first residual signal is encoded to produce a first encoded residual signal. The first encoded residual signal and the first encoded signal may be received and decoded by a decoder to reconstruct the signal. The signal may comprise a set of frames of video.
