Abstract
This disclosure relates to video coding and more particularly to techniques for signaling a picture type in coded video. According to an aspect of an invention, 4 bits NAL unit type information in a NAL unit header is decoded; and a NAL unit type indicating that a content of a NAL unit is trailing picture is determined.
Claims5
(canceled)
2:
- A method of decoding video data, the method comprising:
- receiving a network abstraction layer unit header including syntax elements corresponding to a network abstraction layer unit,
- wherein the network abstraction layer unit header consists of two bytes;
- parsing a five bits syntax element from the network abstraction layer header specifying a type corresponding to the network abstraction layer unit;
- parsing a three bit syntax element from the network abstraction layer header specifying a temporal identifier for the network abstraction layer unit;
- parsing a six bit syntax element from the network abstraction layer header specifying an identifier of a layer corresponding to the network abstraction layer unit;
- and
- generating video data based on values of the parsed syntax elements.

3:
- The method of claim 2, wherein the network abstraction layer unit header includes one reserved zero bit.
4:
- The method of claim 3, wherein the network abstraction layer unit header includes one forbidden zero bit.
5:
- A device for decoding video data, the device comprising one or more processors configured to:
- receive a network abstraction layer unit header including syntax elements corresponding to a network abstraction layer unit,
- wherein the network abstraction layer unit header consists of two bytes;
- parse a five bits syntax element from the network abstraction layer header specifying a type corresponding to the network abstraction layer unit;
- parse a three bit syntax element from the network abstraction layer header specifying a temporal identifier for the network abstraction layer unit;
- parse a six bit syntax element from the network abstraction layer header specifying an identifier of a layer corresponding to the network abstraction layer unit;
- and
- generate video data based on values of the parsed syntax elements.
