| 41 | | * Allow users to select a subset of channels from a larger set. For example, in the United States, CATV companies have created three tiers of service. "Analog", where the channels go from 1 to 25 or so. Can be tuned using a standard NTSC analog tuner. "DTA" - Digital Terminal Adapter. Analog (typically baseband) output, can tune channels 1 through 125. "Digital", a full set-top-box, which can tune channels 1 to 9999. Typically has high-def outputs. "DTA" is a subset of "Digital", but there is no easy way for the user to remove channels above 125 and apply them only to encoder cards which are connected to a DTA. |
