Inter-layer syntax prediction control
An apparatus for coding video information according to certain aspects includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video information associated with a base layer, an enhancement layer, or both. The processor is operationally coupled to the memory unit and is configured to provide a first indicator configured to enable or disable inter-layer syntax prediction and to provide a second indicator configured to enable or disable inter-layer texture prediction. The first and second indicators can be provided separately from each other. In one embodiment, the processor is further configured to disable inter-layer syntax prediction based at least in part upon information indicative of a codec associated with the base layer.
1. An apparatus for decoding video information, the apparatus comprising:
a memory configured to store video data associated with at least one of a base layer or an enhancement layer; and
a processor operationally coupled to the memory and configured to:
receive an indication indicating a codec associated with the base layer in at least one of a video parameter set or a video parameter set extension;
in response to the indication that the codec associated with the base layer is High Efficiency Video Coding (HEVC) codec, receive a non-binary indication having a value selected from a group comprising at least three values in at least one of the video parameter set or the video parameter set extension;
determine, based on the value of the non-binary indication whether inter-layer syntax prediction is to be enabled or disabled;
determine, based on the value of the non-binary indication whether inter-layer texture prediction is to be enabled or disabled; and
perform at least one of inter-layer syntax prediction or inter-layer texture prediction based on the value of the non-binary indication,
wherein the determination of whether inter-layer syntax prediction is to be enabled or disabled and the determination of whether inter-layer texture prediction is to be enabled or disabled are independent of each other.
2. The apparatus of claim 1 , wherein the non-binary indication and the indication indicating a codec associated with the base layer respectively comprise first and second flags or respectively comprise first and second syntax elements.
3. The apparatus of claim 1 , wherein the non-binary indication and the indication indicating a codec associated with the base layer comprise different flags or comprise different syntax elements.
4. The apparatus of claim 1 , wherein the apparatus comprises at least one of a desktop computer, a notebook computer, a laptop computer, a tablet computer, a set-top box, a telephone handset, a smart phone, a smart pad, a television, a camera, a display device, a digital media player, a video gaming console, an in-car computer, a video streaming device, or a device equipped for wireless communication.
5. A method of decoding video information, comprising:
receiving an indication indicating a codec associated with a base layer in at least one of a video parameter set or a video parameter set extension;
in response to the indication that the codec associated with the base layer is High Efficiency Video Coding (HEVC) codec, receiving a non-binary indication having a value selected from a group comprising at least three values in at least one of the video parameter set or the video parameter set extension;
determining, based on the value of the non-binary indication whether inter-layer syntax prediction is to be enabled or disabled;
determining, based on the value of the non-binary indication whether inter-layer texture prediction is to be enabled or disabled; and
performing at least one of inter-layer syntax prediction or inter-layer texture prediction based on the value of the non-binary indication, wherein the determination of whether inter-layer syntax prediction is to be enabled or disabled and the determination of whether inter-layer texture prediction is to be enabled or disabled are independent of each other.
6. The method of claim 5 , wherein the non-binary indication and the indication indicating a codec associated with the base layer respectively comprise first and second flags or respectively comprise first and second syntax elements.
7. The method of claim 5 , wherein the non-binary indication and the indication indicating a codec associated with the base layer comprise different flags or comprise different syntax elements.
8. A non-transitory, computer-readable storage medium storing instructions, that when executed by a processor, cause the processor to:
receive an indication indicating a codec associated with a base layer in at least one of a video parameter set or a video parameter set extension;
in response to the indication that the codec associated with the base layer is High Efficiency Video Coding (HEVC) codec, receive a non-binary indication having a value selected from a group comprising at least three values in at least one of the video parameter set or the video parameter set extension;
determine, based on the value of the non-binary indication whether inter-layer syntax prediction is to be enabled or disabled;
determine, based on the value of the non-binary indication whether inter-layer texture prediction is to be enabled or disabled; and
perform at least one of inter-layer syntax prediction or inter-layer texture prediction based on the value of the non-binary indication,
wherein the determination of whether inter-layer syntax prediction is to be enabled or disabled and the determination of whether inter-layer texture prediction is to be enabled or disabled are independent of each other.
9. The non-transitory, computer-readable storage medium of claim 8 , wherein the non-binary indication and the indication indicating a codec associated with the base layer respectively comprise first and second flags or respectively comprise first and second syntax elements.
10. A means for decoding video information, comprising:
means for receiving an indication indicating a codec associated with a base layer in at least one of a video parameter set or a video parameter set extension;
in response to the indication that the codec associated with the base layer is High Efficiency Video Coding (HEVC) codec, means for receiving a non-binary indication having a value selected from a group comprising at least three values in at least one of the video parameter set or the video parameter set extension;
means for determining, based on the value of the non-binary indication whether inter-layer syntax prediction is to be enabled or disabled;
means for determining, based on the value of the non-binary indication whether inter-layer texture prediction is to be enabled or disabled; and
means for performing at least one of inter-layer syntax prediction or inter-layer texture prediction based on the value of the non-binary indication,
wherein the determination that inter-layer syntax prediction is to be enabled or disabled and the determination of whether inter-layer texture prediction is to be enabled or disabled are independent of each other.
11. The means for decoding video information of claim 10 , wherein the non-binary indication and the indication indicating a codec associated with the base layer respectively comprise first and second flags or respectively comprise first and second syntax elements.
