Publication number: 20230421813Abstract: An encoding device evaluates a plurality of processing and/or post-processing algorithms and/or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods/algorithms either in an encoded bitstream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm/method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm/method at the decoder/post-processor and/or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm may include any of upconversion and/or error correction techniques that contribute to a restoration of the downsampled images.Type: ApplicationFiled: September 14, 2023Publication date: December 28, 2023Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Alexandros TOURAPIS, Athanasios LEONTARIS, Peshala V.
