Error Control in Multi-Stream EDR Video Codec

摘要

Error control in multi-stream visual dynamic range (VDR) codecs is described, including for a case of a layer-decomposed (non-backward compatible) video codecs. Error control can be provided by concealing lost and/or corrupted data in data frames of a decoded VDR bitstream prior to rendering a corresponding VDR image. Various algorithms and methods for concealing lost and/or corrupted data are provided.

主权项

1. A method for concealing effects of errors in a decoded visual dynamic range (VDR) combination stream, the method comprising:
receiving a decoded VDR combination stream, the decoded VDR combination stream comprising a reference picture unit (RPU) stream in correspondence of a plurality of RPU frames and one or more video content streams in correspondence of a plurality of content frames; receiving a reliability flag in correspondence of an erroneous and/or missing current frame of a stream of the decoded VDR combination stream, the erroneous and/or missing current frame being an RPU frame, or a content frame; based on the receiving, replacing data of the erroneous and/or missing current frame with replacement data based on data in one or more frames of the same stream, the one or more frames being different from the current frame, and based on the replacing, concealing effects of the erroneous and/or missing current frame on a corresponding reconstructed VDR image.
