Abstract

Methods, apparatus and systems for video bitstream generation and parsing are described. One example method of video bitstream processing includes parsing a header at a video unit level in a video bitstream for a first field indicative of whether the video unit includes multiple network abstraction layer bit units having multiple types, parsing, due to determining that the video unit includes multiple network abstraction layer bit units having multiple types, a second field in the header indicative of whether the video unit comprises an intra random access point, and decoding, based on the first field and the second field, the video bitstream to generate a video.
