Abstract
A method and apparatus for performing maximum transform size control for decoding of a video sequence includes identifying, by a decoder, a high-level syntax element associated with the video sequence. A maximum transform size associated with the video sequence is determined based on identifying the high-level syntax element associated with the video sequence. The video sequence is decoded using the maximum transform size based on determining the maximum transform size associated with the video sequence. The video sequence is transmitted based on decoding the video sequence using the maximum transform size.
Claims20
A method for performing maximum transform size control for decoding of a video sequence, the method comprising:
- identifying, by a decoder, a high-level syntax element associated with the video sequence;
- determining, by the decoder, a maximum transform size associated with the video sequence based on identifying the high-level syntax element associated with the video sequence;
- decoding, by the decoder, the video sequence using the maximum transform size based on determining the maximum transform size associated with the video sequence;
- and
- transmitting, by the decoder, the video sequence based on decoding the video sequence using the maximum transform size.
A device for performing maximum transform size control for decoding of a video sequence, comprising:
- at least one memory configured to store program code;
- at least one processor configured to read the program code and operate as instructed by the program code, the program code including:
- identifying code configured to cause the at least one processor to identify a high-level syntax element associated with the video sequence;
- determining code configured to cause the at least one processor to determine a maximum transform size associated with the video sequence based on identifying the high-level syntax element associated with the video sequence;
- decoding code configured to cause the at least one processor to decode the video sequence using the maximum transform size based on determining the maximum transform size associated with the video sequence;
- and
- transmitting code configured to cause the at least one processor to transmit the video sequence based on decoding the video sequence using the maximum transform size.
A non-transitory computer-readable medium storing instructions, the instructions comprising:
- one or more instructions that, when executed by one or more processors of a device for performing maximum transform size control for decoding of a video sequence, cause the one or more processors to:
- identify a high-level syntax element associated with the video sequence;
- determine a maximum transform size associated with the video sequence based on identifying the high-level syntax element associated with the video sequence;
- decode the video sequence using the maximum transform size based on determining the maximum transform size associated with the video sequence;
- and
- transmit the video sequence based on decoding the video sequence using the maximum transform size.
