Embodiment
There has been described the renewal for profile_tier_level syntactic structure, these upgrade and are used for when in the vps_extensions () syntactic structure being used for every one deck or operating point, support the extra flexibility that HEVC expands.
Here is the profile_tier_level syntactic structure presented in present international standards draft (DIS) specification for high efficiency Video coding (HEVC).
The current external parameter mark by being used as the profilePresentFlag of " transmission " parameter in the profile_tier_level syntactic structure in DIS that exists of the grammar parameters that profile_tier_level is correlated with restricts (restriction).Under indicate when during this syntactic structure is for vps_extension () syntactic structure with support various HEVC expand require time, which parameter can be restricted.
Selectable grammar parameters in current profile_tier_level (DIS)
Obviously, of being called in the parameter group of " general_profile_tier " comprising the general grammer of " profile_tier_only " can not be for the possible selection in vps_extension () syntactic structure.In other words, by existing profile_tier_level syntactic structure, all possible selection may not be all possible.This is because do not exist " levelPresentFlag ", this is another conditional mark, as the outside Transfer Parameters being similar to " profilePresentFlag ", or as the grammer that profile_tier_level syntactic structure inside is added.
In current HEVC specification, Profile and Tier relevant parameter can be set to 1 or 0 based on by ProfilePresentFlag, each Layer or the change of operating point ground.Generally, revise Level parameter all the time, and if sub_layer_level_present_flag exists, so, the level parameters that sublayer is relevant can be changed.
But describe from Profile/Tier/Level, Level parameter can be general to some configuration file/layer situation, and can change other situations.Exist for ordinary circumstance, the possibility that Level parameter can change dividually with Profile/Tier parameter change.In other words, Level parameter by by newly indicating that LevelPresentFlag is set to 1 or 0, can change.
Following figure indicates when " levelPresentFlag " is as when being similar to the Transfer Parameters of " profilePresentFlag " or existing as the grammer of the interpolation of profile_tier_level syntactic structure inside, and how the profile_tier in the profile_tier_level syntactic structure of amendment and all possible combination of level parameters be all possible at it in application process in vps_extension ().
Selectable grammar parameters in the profile_tier_level upgraded
1) profilePresentFlag is for general and sublayer situation, enables the restriction (existence) of configuration file and layer grammer in the syntactic structure above
2) in current_profile_tier_level syntactic structure, such mark is not had, to affect (restriction) for LevelIDC grammar parameters that is general and sublayer situation.So, in vps_extension (), for layer or operating point (OP), restriction can not be applied to the existence of LevelIDC.
3) profile_tier_level syntactic structure can be upgraded as follows: use " levelPresentFlag " as the Transfer Parameters being similar to " profilePresentFlag ", or insert levelPresentFlag, as 1 new Bit Syntax.
The following shows the profile_tier_level syntactic structure of renewal, using levelPresentFlag as Transfer Parameters, be similar to profilePresentFlag.
The vps_extension () before defined uses vps_profile_tier syntactic structure, and for all layers (i=1 to vps_max_layers_minus1), profilePresentFlag is set to 1 all the time, as shown below.In the ordinary course of things, for profile_tier or level of grammar parameter, not restriction.
A few joint below, achieve when the profile_tier_level syntactic structure revised with specific to layer or in being used from vps_extension () specific to the renewal one of operating point (OP) time, two kinds of modes of such grammar parameters of restriction profile_tier and/or rank.
The renewal specific to layer of the profile_tier_level in vps_extension ()
In superincumbent syntactic structure, introduce four new grammar parameters:
Vps_profile_present_flag [i]: when this mark equals 1, the profile information of this designated layer (Layer) i is present in profile_tier_level () syntactic structure.When this mark equals 0, the profile information of this designated layer i is not present in profile_tier_level () syntactic structure.
Vps_profile_ref_layer_num [i]: when vps_profile_present_flag [i] equals 0, infer that the profile information of layer i equals the profile information of the layer indicated by vps_profile_ref_layer_num [i], the index of the Reference Profile-Tier_Level look-up table of such information of the layer that layer numbering sends before being used as storing.
Vps_level_present_flag [i]: when this mark equals 1, the class information of this designated layer i is present in level_tier_level () syntactic structure.When this mark equals 0, the class information of this designated layer i is not present in level_tier_level () syntactic structure.
Vps_level_ref_layer_num [i]: when vps_level_present_flag [i] equals 0, infer that the class information of layer i equals the class information of the layer indicated by vps_level_ref_layer_num [i], the index of the Reference Profile-Tier-Level look-up table of such information of the layer that layer numbering sends before being used as storing.
The combined effect of the value of vps_profile_present_flag and vps_level_present_flag has been shown in chart below, wherein, such grammar parameters mark is present in the vps_extension () syntactic structure of amendment shown above.
| vps_profile_present_flag | vps_level_present_flag | Available grammar parameters |
| 0 | 0 | (Reference-Profile/Tier,LevelIdc) |
| 0 | 1 | (Reference-Profile/Tier),LevelIdc |
| 1 | 0 | Profile/Tier,(Reference-LevelIdc) |
| 1 | 1 | Profile/Tier,LevelIdc |
Exemplarily, when " vps_profile_present_flag " and " vps_level_present_flag " both 0 (chart above), available grammar parameters is " (Reference-Profile/Tier; LevelIdc) ", this means, when such parameter is comparatively early sent out, all such parameters can from store or obtain " Reference " look-up table.Such reference parameter has been described in two grammar parameters vps_profile_ref_layer_num and vps_level_ref_layer_num.Such " vps_profile_present_flag " and " vps_level_present_flag " is used to help to avoid unknown condition.
The renewal specific to OP of the profile_tier_level in vps_extension ()
In superincumbent syntactic structure, introduce four new grammar parameters, be similar to " renewal specific to the rank " situation in last joint.
Vps_profile_present_flag [i]: when this mark equals 1, the profile information of this assigned operation point i (or OP i) is present in level_tier_level () syntactic structure.When this mark equals 0, this specifies the profile information of OP i not to be present in profile_tier_level () syntactic structure.
Vps_profile_ref_op_num [i]: when vps_profile_present_flag [i] equals 0, infer that the profile information of OP i equals the profile information of the OP indicated by vps_profile_refjayer_num [i], OP numbering is used as the index of the Reference Profile-Tier-Level look-up table of the such information storing the OP previously sent.
Vps_level_present_flag [i]: when this mark equals 1, this specifies the class information of OP i to be present in level_tier_level () syntactic structure.When this mark equals 0, this specifies the class information of OP i not to be present in level_tier_level () syntactic structure.
Vps_level_ref_op_num [i]: when vps_level_present_flag [1] equals 0, infer that the class information of OP i equals the class information of the OP indicated by vps_level_ref_layer_num [1], OP numbering is used as the index of the Reference Profile-Tier-Level look-up table of the such information storing the OP previously sent.
If " LevelPresentFlag " this new mark is used for " profile_tier_level " syntactic structure, so its initialization in VPS and SPS as follows:
| video_parameter_set_rbsp(){ | Descriptor |
| .....................Edited............................ | |
| profile_tier_level(1,1,vps_max_sub_layers_minus1) | |
| .....................Edited............................ | |
| } |
As described herein, make the renewal to profile_tier_level syntactic structure, with in scalable video coding, multi-view coded and 3D field of video encoding, the extra flexibility in the profile_tier selecting to be used for HEVC expansion and level parameters.After this, syntactic structure of this amendment is used in vps_extension () syntactic structure, wherein, limits profile_tier and level of grammar parameter in two kinds of possible modes, is for every one deck or is for each operating point.
