Abstract
Disclosed herein are a media file generation/receiving method based on an EOS sample group and a method of transmitting a media file. The media file receiving method may comprise obtaining one or more tracks and a sample group from a media file and reconstructing an access unit based on samples in the tracks and the sample group. The sample group may comprise a first sample group including end of sequence (EOS) information of video data to which the access unit belongs, and the first sample group may comprise one or more EOS NAL units and a first syntax element related to the number of EOS NAL units.
Claims13
A media file receiving method performed by a media file receiving apparatus, comprising:
- obtaining one or more tracks and a sample group from a media file;
- and
- reconstructing an access unit based on samples in the tracks and the sample group,
- wherein the sample group includes a first sample group including end of sequence (EOS) information of video data to which the access unit belongs,
- wherein the first sample group includes one or more EOS NAL units and a first syntax element related to the number of EOS NAL units, and
- wherein a maximum index value of the EOS NAL units is equal to a value of the first syntax element.
A media file receiving apparatus comprising a memory and at least one processor, wherein the at least one processor is configured to:
- obtain one or more tracks and a sample group from a media file;
- and
- reconstruct an access unit based on samples in the tracks and the sample group,
- wherein the sample group includes a first sample group including end of sequence (EOS) information of video data to which the access unit belongs,
- wherein the first sample group includes one or more EOS NAL units and a first syntax element related to the number of EOS NAL units, and
- wherein a maximum index value of the EOS NAL units is equal to a value of the first syntax element.
A media file generating method performed by a media file generating apparatus, comprising:
- encoding video data including an access unit;
- generating a first sample group including end of sequence (EOS) information of the encoded video data;
- and
- generating a media file based on the encoded video data and the first sample group,
- wherein the first sample group includes one or more EOS NAL units and a first syntax element related to the number of EOS NAL units, and
- wherein a maximum index value of the EOS NAL units is equal to a value of the first syntax element.
A media file generating apparatus comprising a memory and at least one processor, wherein the at least one processor is configured to:
- encode video data including an access unit;
- generate a first sample group including end of sequence (EOS) information of the encoded video data;
- and
- generate a media file based on the encoded video data and the first sample group,
- wherein the first sample group includes one or more EOS NAL units and a first syntax element related to the number of EOS NAL units, and
- wherein a maximum index value of the EOS NAL units is equal to a value of the first syntax element.
