Details
- Description
- A KAG is used to align certain KLV elements to specific byte boundaries. In MXF, this is achieved by the insertion of KLV Fill items which ensure that the desired KLV elements are aligned. The KAGSize defines the size of the KLV Alignment Grid (KAG) for this Partition, in bytes.
- Definition
- Used in Checks, the system shall read out the KAG Size from the wrapper partition pack metadata and check it against the expected KAG Size. Optionally it may report the KAG Size value.
Used in Reports, the system shall read out the KAG Size from the wrapper partition pack metadata and report it. - References
