主权项

1. A method, comprising:
determining a first tier number from a tier assertion field for a first picture received in an AVC stream, wherein the encoded first picture includes a memory management control operation (MMCO), wherein decoding of a second picture depends on processing the MMCO, wherein the tier assertion field comprises a number of bits corresponding to a number of available tiers; and interpreting the first tier number based on which of the number of bits is set to a first value.
