SVC FILE DATA SHARING METHOD AND SVC FILE THEREOF |
摘要 |
A method of sharing data of a scalable video coding (SVC) file and the SVC file are provided. The SVC file includes: a scalable base track including at least one scalable layer entry each storing metadata of the at least one scalable layer; and at least one sub track generated based on the scalable base track, which includes identification information of the scalable layer that is a basis of generation of a sub track among the scalable layers and identification information of the scalable base track instead of the scalable layer entry. Accordingly, when an SVC coded content is stored as a file, it is possible to reduce a storage capacity by avoiding duplication of common data and to provide convenience when the stored content is reprocessed by allowing a relation of tracks correlated to one another to be represented. |
