Video coding system with temporal layers and method of operation thereof
An encoding apparatus of a video coding system includes a setting unit and an encoder which is connected to the setting unit. The setting unit sets video usability information (VUI) parameter including field_seq_flag. The field_seq_flag indicates whether a video stream includes a video representing field and common to all occurrences of a temporal layer. The encoder encodes the video stream based on the temporal layer to generate an encoding bitstream including the VUI set by the setting unit.
1. An encoding apparatus, comprising:
a setting unit configured to set video usability information (VUI) parameter including a field_seq_flag,
wherein the field_seq_flag indicates whether a video stream includes a video representing field, and
wherein the field_seq_flag has a value that is constant across all occurrences of a temporal layer; and
an encoder connected to the setting unit, wherein the encoder is configured to:
encode the video stream based on the temporal layer; and
generate, based on the encoded video stream, an encoding bitstream that includes the VUI parameter set by the setting unit.
2. The encoding apparatus of claim 1 , wherein the setting unit is further configured to set the VUI parameter as syntax common to all the occurrences of the temporal layer.
3. The encoding apparatus of claim 1 , wherein the VUI parameter further includes a timing_info_present_flag.
4. The encoding apparatus of claim 3 , wherein each VUI parameter related to the timing_info_present_flag is common to all the occurrences of the temporal layer.
5. The encoding apparatus of claim 1 , wherein the setting unit is further configured to set a hypothetical reference decoder (HRD) parameter common to all the occurrences of the temporal layer.
6. The encoding apparatus of claim 1 , wherein the setting unit is further configured to set a different hypothetical reference decoder (HRD) parameter for each occurrence of the temporal layer.
7. An encoding method, comprising:
setting video usability information (VUI) parameter including a field_seq_flag,
wherein the field_seq_flag indicates whether a video stream includes a video representing field, and
wherein the field_seq_flag has a value that is constant across all occurrences of a temporal layer;
encoding the video stream based on the temporal layer; and
generating, based on the encoded video stream, an encoding bitstream that includes the set VUI parameter.
8. The encoding method of claim 7 , wherein the VUI parameter is set as syntax common to all the occurrences of the temporal layer.
9. The encoding method of claim 7 , wherein the VUI parameter further includes a timing_info_present_flag.
10. The encoding method of claim 9 , wherein each VUI parameter related to the timing_info_present_flag is common to all the occurrences of the temporal layer.
11. The encoding method of claim 7 , further comprising:
setting a hypothetical reference decoder (HRD) parameter common to all the occurrences of the temporal layer.
12. The encoding method of claim 7 , further comprising:
setting a hypothetical reference decoder (HRD) parameter for each occurrence of the temporal layer.
