TVtips "Broadcast-Controlled" Color The electronic signal that produced your favorite TV show last night may have traveled thousands of miles through space, under water, over land and through the air before reaching your living room. The signal passed through so many different wires, antennas, and amplifiers ampli-fiers that the color finally seen in your home may not have been the color the program's director wanted you to see. n That's why many TV programs pro-grams are now broadcast with a recently-developed color reference ref-erence called a vertical interval inter-val reference (VIR) signal. The signal allows broadcast technicians tech-nicians at each link of the complicated com-plicated communications chain from studio to local station to determine whether the color they are receiving and rehrond-casting rehrond-casting is the color certified at the broadcast's source. Mow-ever, Mow-ever, the final link of the chain, the home television, has remained beyond the broadcaster's control. But now, the first home television tele-vision sets that monitor the broadcaster's VIR signals (all three major networks use them), automatically adjusting adjust-ing color intensity and tint accordingly, ac-cordingly, are available from General Electric. When the VIR switch is set to "on" the set automatically adjusts itself to a corrected color picture.
