Simulcast

Technology / Television (TV) / Simulcast: The broadcast of programming over two separate channels or forms of media at the same time. For example, during the transition period (at least through 2006), WCET will often simulcast Channel 48 programming on Channel 34. Of course if the program is in HDTV, the Channel 34 program content will be the same but the picture and sound of much higher quality.
