Operations that are aware of the syntax of media files in container format

摘要

Provided is a method for performing a syntax-conscious operation of hierarchically organized syntax elements. A container format processing tool performs an operation in consideration of the syntax of hierarchically organized syntax elements defined by a container format in a media file. For example, a container format verifier checks the suitability of a media file for a container format, which can help ensure interoperability between various sources of media content and playback devices. Conformance verification can include verification of individual syntax elements, cross-validation, verification that required syntax elements are present, and / or synchronization verification.
