Digital 3&4's PSB2 multiplex contains a number of channels and radio services. It must carry ITV (TV network), Channel 4 and, since 2009, Channel 5.^[4] Prior to 2010, 3% of the capacity was allocated to Teletext Ltd for interactive services.^[5] Digital 3&4 has used the rest of the multiplex's capacity to broadcast other channels from their parent companies or other broadcasters who pay Digital 3&4 a fee. Unlike other multiplexes, the regional ITV broadcaster has control over which services are to be broadcast on their allotted amount of the capacity, leading to small regional differences across the country.
