Abstract
The present invention relates to a method for storing image data, and a method for parsing image data, and an apparatus for using the same, which method includes the steps of encoding the image data, and storing an NAL (Network Abstraction Layer) unit containing the encoded image data in the decoder set register in which NAL units may be stored according to the type of NAL unit.
Claims20
A method of storing video information, the method comprising:
- deriving network abstraction layer (NAL) units including encoded video information;
- configuring a decoder configuration record syntax;
- and
- generating a media file including the decoder configuration record syntax,
- wherein the NAL units are comprised in the decoder configuration record syntax of the media file,
- wherein the decoder configuration record syntax includes one or more NAL unit type syntax elements, wherein a NAL unit type syntax element variably indicates a NAL unit type among NAL unit types of a NAL unit type group including a sequence parameter set (SPS) NAL unit type, a picture parameter set (PPS) NAL unit type and a supplemental enhancement information (SEI) NAL unit type,
- wherein in the decoder configuration record syntax, the NAL units are stored per NAL unit type indicated by each of the NAL unit type syntax elements of the decoder configuration record syntax, and
- wherein the decoder configuration record syntax includes one or more NAL unit length syntax elements, wherein each of the NAL unit length syntax elements indicates a length of an associated NAL unit among the NAL units.

A method of parsing video information, the method comprising:
- obtaining a decoder configuration record syntax from a received media file;
- and
- parsing one or more NAL unit type syntax elements comprised in the decoder configuration record syntax, wherein a NAL unit type syntax element variably indicates a NAL unit type among NAL unit types of a NAL unit type group including a sequence parameter set (SPS) NAL unit type, a picture parameter set (PPS) NAL unit type and a supplemental enhancement information (SEI) NAL unit type;
- and
- parsing NAL units comprised in the decoder configuration record syntax per NAL unit type indicated by each of the NAL unit type syntax elements of the decoder configuration record syntax,
- wherein the decoder configuration record syntax includes one or more NAL unit length syntax elements, wherein each of the NAL unit length syntax elements indicates a length of an associated NAL unit among the NAL units.

An apparatus of storing video information, the apparatus comprising:
- an encoding unit configured to encode video information;
- and
- a processing unit configured to derive NAL (Network Abstraction Layer) units including the encoded video information, and to generate a media file including the NAL units,
- wherein the NAL units are comprised in a decoder configuration record syntax of the media file,
- wherein the decoder configuration record syntax includes one or more NAL unit type syntax elements, wherein a NAL unit type syntax element variably indicates a NAL unit type among NAL unit types of a NAL unit type group including a sequence parameter set (SPS) NAL unit type, a picture parameter set (PPS) NAL unit type and a supplemental enhancement information (SEI) NAL unit type, and
- wherein in the decoder configuration record, the NAL units are stored or signaled per NAL unit type indicated by each of the NAL unit type syntax elements of the decoder configuration record syntax,
- wherein the decoder configuration record syntax includes one or more NAL unit length syntax elements, wherein each of the NAL unit length syntax elements indicates a length of an associated NAL unit among the NAL units.
4 more elements
An apparatus of parsing video information, the method comprising:
- a parsing unit configured to obtain a decoder configuration record syntax from a received media file, and to parse one or more NAL unit type syntax elements comprised in the decoder configuration record syntax, wherein a NAL unit type syntax element variably indicates a NAL unit type among NAL unit type of a NAL unit types group including a sequence parameter set (SPS) NAL unit type, a picture parameter set (PPS) NAL unit type and a supplemental enhancement information (SEI) NAL unit type;
- and
- a decoding unit configured to parse the NAL units comprised in the decoder configuration record syntax per NAL unit type indicated by each of the NAL unit type syntax elements of the decoder configuration record syntax,
- wherein the decoder configuration record syntax includes one or more NAL unit length syntax elements, wherein each of the NAL unit length syntax elements indicates a length of an associated NAL unit among the NAL units.
