The transmission of Multichannel Television Sound (MTS) is a reality; over 200 stations are now operational in the stereo mode. ·The technical effect of carrying the MTS signal over cable television systems is not yet clearly understood. In order to understand what effect our systems have on carriage of MTS, a testing program was designed and implemented using link analysis. This testing program included each system component from the broadcaster's master control, through to the end of a cable cascade. This presentation will document the measured results of that testing, and method used.
