Abstract
In a compressed domain digital communications system, a method for reducing a variable latency associated with a buffer and at least partially resulting from at least one splice between a FROM bitstream and a TO bitstream each including data corresponding to a plurality of frames, the method including: selectively deleting data corresponding to a select at least one of the frames from the buffer based upon the variable latency so as to reduce the variable latency when an amount of data corresponding to a number of frames present in the buffer is greater than a given number of frames; and, regulating a flow of data in the system to prevent an underflow condition in the system by effecting a repeat last frame command and prevent an overflow condition in the system by slowing a rate of transmission for the data associated with at least one of the frames in the TO bitstream.
