A SYSTEM AS DESCRIBED HEREIN ENABLES A USER TO ACCESS AUXILIARY INFORMATION WHEN VIEWING AN ENHANCED PERFORMANCE TELEVISION SIGNAL OR PROGRAM. PARTICULARLY, A TELEVISION SIGNAL SYSTEM IS OPERATIVE, CONFIGURED, AND/OR ENABLED TO ALLOW A USER TO ACCESS AND/OR UTILIZE AUXILIARY INFORMATION WHEN VIEWING A HIGH DEFINITION OR PROGRESSIVE-SCAN TELEVISION SIGNAL. BRIEFLY, AN EXEMPLARY TELEVISION SIGNAL SYSTEM RECEIVES THE AUXILIARY INFORMATION/DATA (E.G. CLOSED CAPTION DATA) ON A SELECTED INTERLACED STANDARD DEFINITION INPUT, PROCESSES THE AUXILIARY DATA, AND COMBINES OR OVERLAYS THE AUXILIARY DATA WITH A TELEVISION (VIDEO) SIGNAL RECEIVED ON A SELECTED INPUT THAT DOES NOT HAVE ITS OWN EMBEDDED AUXILIARY INFORMATION/DATA.; MORE PARTICULARLY, AN EXEMPLARY TELEVISION SIGNAL SYSTEM SUCH AS DESCRIBED HEREIN INVOLVES USING CLOSED CAPTION (CC) DATA FROM A STANDARD DEFINITION SIGNAL, PROCESSING THE CC DATA, AND OVERLAYING THE CC DATA AT A VIDEO RATE OF A HIGHER DEFINITION SIGNAL SELECTED FOR VIEWING THAT DOES NOT CARRY ITS OWN EMBEDDED CLOSED CAPTION DATA.
