TV broadcasters must determine what type of MTS service to provide their viewers in line with the competitive situation in the marketplace. Some stations will elect to provide only synthesized stereo, others will make provisions for network-originated stereo, still others will install facilities for playback of feature films and syndicated tapes in stereo, and finally there will be those stations that will want to produce programs in stereo. Additionally, the broadcaster must determine if the use of the SAP and PRO channels is desirable.
