Abstract

IN A DIGITAL TELEVISION SIGNAL PROCESSING SYSTEM, A SPECIAL CODEWORD, A PACKET ALIGNMENT FLAG (PAF), IS INSERTED (14) INTO AN MPEG CODEWORD BITSTREAM TO SIGNIFY THE PRESENCE OF A GROUP OF PICTURES (GOP). THE PAF IMMEDIATELY PRECEDES A PICTURE START CODEWORD FOR AN "I" FRAME, WHICH INITIATES A GOP. A DATA PACKET UNDER CONSTRUCTION (12) WHEN A PAF APPEARS IS TERMINATED SINCE A GOP IS INTENDED TO BEGIN AT A PACKET BOUNDARY. SUCH TERMINATION MAY RESULT IN AN ABBREVIATED PACKET OF LESS THAN A PRESCRIBED NUMBER CODEWORDS NEEDED TO COMPLETE A DATA PACKET. THE LAST WORD OF EACH PACKET IS DESIGNATED AS SUCH TO FACILITATE THE SUBSEQUENT COMBINING (15) OF DATA PACKETS WITH RESPECTIVE HEADERS. AN INCOMPLETE DATA PACKET IS FILLED (15) WITH NULL (ZEROED BITS) WORDS TO MAKE A COMPLETE DATA PACKET WITH A PRESCRIBED NUMBER OF WORDS. FIG. 17
