Digital 3&4

Digital 3&4

Digital 3&4 is a consortium consisting of regional Channel 3 companies and Channel 4 Television Corporation, which operates a multiplex broadcasting from a number of transmitter sites in the UK, carrying television and radio channels (in addition to interactive services) from both ITV and Channel 4; however three per-cent of the capacity is gifted to Teletext Ltd. Unlike other multiplexes, the regional ITV broadcaster has control into which services are to be broadcast on their alloted amount of the capacity, and this can be shown by the small regional differences across the country.
