Patent ID: 10148983

Abstract:
Systems, methods, and computer readable media are described for providing improved video coding, including improved video stream switching and random access. In some examples, systems, methods, and computer readable media include obtaining video data at an encoder and determining, from the video data, an intra random access point (IRAP) picture. A first set of one or more leading pictures associated with the IRAP picture are coded as random access decodable leading (RADL) pictures based on the first set of one or more leading pictures having a temporal identifier (TemporalId) that is less than or equal to a TemporalId threshold value. A second set of one or more leading pictures associated with the IRAP picture are coded as random access skipped leading (RASL) pictures based on the second set of one or more leading pictures having a TemporalId that is greater than the TemporalId threshold value. The video bitstream can then be generated to include the IRAP picture, the first set of one or more leading pictures, and the second set of one or more leading pictures.
