Abstract
An unused value of the general_profile_space syntax element can be used to indicate that a layer with a non-zero value of nuh_layer_id in a multi-layer bitstream is otherwise conforming to a profile.
Claims18
A method for indicating Video-Coding-Layer (VCL-) conformance of a second coded picture layer of a coded video bitstream with an HEVC version 1 decoder in a decoder, the method comprising:
- receiving and decoding a video parameter set comprising at least two entries, each entry comprising a profile-tier-level structure,
- the first entry pertaining to a primary coded picture layer having a first layer_id equal to zero, a field general profile_space equal to zero, and a first combination of profile, tier, and level,
- the second entry pertaining to a second coded picture layer having a second layer_id not equal to 0, a field general_profile_space, and a second combination of profile, tier, and level, and
- indicating VCL-conformance with an HEVC version 1 decoder if the field general_profile_space of the second entry is non-zero and the HEVC version 1 decoder is capable of decoding a bitstream compliant with the second entry with the field general_profile_space of the second entry assumed to be equal to 0,
- wherein the second coded picture layer is not a temporal enhancement layer of the primary coded picture layer.

A system for indicating Video-Coding-Layer (VCL-) conformance of a second coded picture layer of a coded video bitstream with an HEVC version 1 decoder in a decoder, the system comprising:
- a decoder (including a combination of hardware and software) configured to:
- receive and decode a video parameter set comprising at least two entries, each entry comprising a profile-tier-level structure,
- the first entry pertaining to a primary coded picture layer having a first layer_id equal to zero, a field general profile_space equal to zero, and a first combination of profile, tier, and level,
- the second entry pertaining to a second coded picture layer having a second layer_id not equal to 0, a field general_profile_space, and a second combination of profile, tier, and level, and
- indicate VCL-conformance with an HEVC version 1 decoder if the field general_profile_space of the second entry is non-zero and the HEVC version 1 decoder is capable of decoding a bitstream compliant with the second entry with the field general_profile_space of the second entry assumed to be equal to 0,
- wherein the second coded picture layer is not a temporal enhancement layer of the primary coded picture layer.
