Method and apparatus for updating offset fields

摘要

A method and apparatus for updating offsets in a bitstream upon dropping data from the bitstream using a descriptor is provided. The design comprises establishing at least one reference point, at least one numerical offset value, and at least one pointer in the descriptor associated with the bitstream, evaluating whether dropped data from the bitstream comprises at least a portion of the numerical offset value, and either zeroing the numerical offset value or adjusting at least one of the reference point and the pointer when dropped data from the bitstream comprises at least a portion of the numerical offset value.
