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. This Test ensures that all partitions start at the expected grid.
- Definition
- Used in Checks, the system shall measure the KAG Size from the wrapper and check it against the expected KAG Size provided by the user. Optionally it may report the measured KAG Size.
Used in Reports, the system shall measure the KAG Size from the wrapper and report it. - References
