METHOD FOR REAL-TIME INSERTION OF AUXILIARY DATA PACKETS INTO DSS BITSTREAM IN THE PRESENCE OF ONE OR MORE SERVICE CHANNELS.

摘要

An apparatus and method that allows for the automatic, real-time insertion of auxiliary data packets into a single or multi-channel bitstream in a satellite television broadcast system. Computer readable instructions stored in a storage medium provides iterative steps necessary to detect the presence of a data packet within the data bitstream, establish a bitstream data packet counter for storing values representing the number of the data packets encountered in the data bitstream, set the bitstream data packet counter to an initial value, increment the bitstream data packet counter, determine which channel bitstream the detected data packet is associated with and identify the channel as an operative channel bitstream, establish an operative channel data packet counter for the operative channel bitstream for storing values representing the number of the data packets encountered in the operative channel bitstream, set the operative channel data packet counter to an initial value, increm ent the operative channel data packet counter, determine a channel bit rate for the operative channel bitstream, determine a data packet spacing value for the operative channel bitstream, and if the value of the operative channel data packet counter is a multiple of the data packet spacing value for the operative channel bitstream then insert the data packet within the operative channel bitstream.
