Method for storing image information, method for parsing image information and apparatus using same

A method of parsing video information, the method comprising:

• obtaining, by a video information parsing apparatus, a decoder configuration record from a received media file;
• parsing, by the video information parsing apparatus, a NAL unit type syntax element explicitly included in the decoder configuration record, wherein the 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, by the video information parsing apparatus, at least one NAL unit, included in the decoder configuration record, based on the NAL unit type syntax element,
• wherein a NAL unit is parsed according to a NAL unit type specified by the NAL unit type syntax element of the decoder configuration record,
• wherein the at least one NAL unit is stored in the decoder configured record after the NAL unit type syntax element, and
• wherein the decoder configuration record includes a constant frame rate syntax element configured by 2 bits,
• wherein the decoder configuration record includes a NAL unit length syntax element indicating a length of an associated NAL unit corresponding to the NAL unit type, and
• wherein, in the decoder configuration record, the NAL unit type syntax element is configured by 2 bits and the NAL unit length syntax element is configured by 14 bits.

An apparatus of storing video information, comprising:

• an encoding unit for encoding video information;
• and
• a storage unit for obtaining the encoded video information, for deriving network abstraction layer (NAL) units from the encoded video information, and for generating a media file including the NAL units,
• wherein the storage unit configures a decoder configuration record of the media file, wherein the NAL units are included in the decoder configuration record of the media file,
• wherein the decoder configuration record explicitly includes a NAL unit type syntax element, wherein the 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, a NAL unit is stored according to a NAL unit type specified by the NAL unit type syntax element of the decoder configuration record,
• wherein the at least one NAL unit is stored in the decoder configured record after the NAL unit type syntax element, and
• wherein the decoder configuration record includes a constant frame rate syntax element configured by 2 bits,
• wherein the decoder configuration record includes a NAL unit length syntax element indicating a length of an associated NAL unit corresponding to the NAL unit type, and
• wherein, in the decoder configuration record, the NAL unit type syntax element is configured by 2 bits and the NAL unit length syntax element is configured by 14 bits.

An apparatus of parsing video information, comprising:

• and
• a decoding unit decoding video information based on the NAL units including the video information,
• wherein a NAL unit is parsed according to a NAL unit type specified by the NAL unit type syntax element,
• wherein the at least one NAL unit is stored in the decoder configured record after the NAL unit type syntax element, and
• wherein the decoder configuration record includes a constant frame rate syntax element configured by 2 bits,
• wherein the decoder configuration record includes a NAL unit length syntax element indicating a length of an associated NAL unit corresponding to the NAL unit type, and
• wherein, in the decoder configuration record, the NAL unit type syntax element is configured by 2 bits and the NAL unit length syntax element is configured by 14 bits.
