Abstract

The present invention is concerned with decoders, encoders and corresponding methods for handling video data streams (11) comprising a first sub-bitstream (11-1) and a second sub-bitstream (11-2). The herein described concept provides solutions for mixing, within an access unit (30, 31, 32), different NAL units (301, 302, 3030, 304) of different NAL unit types. For example, RAP NAL unit types may be mixed with different IRAP NAL unit types or non-IRAP NAL unit types, and non-IRAP NAL unit types may be mixed with different non-IRAP NAL unit types.
