Abstract
In a CATV system, channel identifying data is incorporated in each transmitted channel, and subscriber terminals return such data to the CATV center to indicate the channel actually being received. Further, the channel identifying data is compared to the channel selected, and when a proper comparison exists a sweep voltage is held at a predetermined level for the particular channel, to control frequency conversion at the terminal.
