The DAT supports a minimum of 400 channels in the channel map; there is no real restriction for the number of
channels supported in the DTA (ie. it can support a lot).
3.1.1 Channel Numbers
The DTA supports 4 digit channel numbers, with a maximum channel number of 4095. In the Virtual Channel Map
(VCM) table of the SI data, the virtual channel field is 12 bits long, resulting in a maximum value of 4095.
3.1.2 Channel Name
The DTA displays a channel name. The channel name length is capped at 14 characters. The character map
includes all valid alphanumeric and symbolic characters. Figure 21 shows an example of the channel name and
number displayed on-screen when the info button is pressed or the channel is changed.
