| | Digital Terrestrial Television. |
 | | In analogue television we see this phenomena as 'ghosts', and these are caused by secondary signals arrive slightly later than normal, after having bounced off buildings, hills, bridges, etc., along the way. |
 | | Analog television in Australia has channels which are 7MHz wide (8MHz in Europe), and so fitting 2000 narrow 'finger' sub-channels into this space isn't all that difficult, and since they are all low-rate, multipath bounce doesn't really effect them unless the delay is substantial. |
 | | Of the current six UHF multiplexes, one is for the BBC (BBC1 and BBC2), one is for the commercial ITV network, and a third goes to Channel 4 and 5 (experimental, semi-commercial). |
