On intra random access point pictures and leading pictures in video coding

Abstract

A method of encoding a video bitstream implemented by a video encoder is disclosed. The method includes storing, in a memory of the video encoder, a set of less than five network abstraction layer (NAL) unit types available for video data; selecting, by a processor of the video encoder, a NAL unit type from the set of less than five NAL unit types for a picture from the video data; generating, by the processor of the video encoder, a video bitstream containing a NAL unit corresponding to the NAL unit type selected and containing an identifier identifying the NAL unit type selected; and transmitting, by a transmitter of the video encoder, the video bitstream toward a video decoder. A corresponding method of decoding the video bitstream is also disclosed.

Description

[0001] Related Application Cross Reference [0002] This patent application requires the application number 62 / 785,515 submitted by Fnu Hendry et al. on December 27, 2018, and the title of the invention is "On Intra Random Access Point Image and Front Image in Video Decoding (On Intra Random Access Point Pictures and Leading Pictures in Video Coding), the entire contents of which are incorporated into this application by reference. technical field [0003] This disclosure generally describes techniques for processing network abstraction layer (NAL) unit types of preceding pictures and intra random access point (IRAP) pictures. More specifically, this disclosure describes techniques for limiting the number of available NAL unit types and for using a flag to indicate whether a picture is decodable if it has not been identified by a NAL unit type. Background technique [0004] Even relatively short videos require large amounts of video data to describe, which can cause difficu...
