Digital terrestrial television

Network Six is a major digital terrestrial television operator, on the service marketed as Freeview. The network receives its gifted universal multiplex, which broadcasts in MPEG2, 64QAM. This allows around 7-9 television channels at fairly high quality to be broadcast, alongside audio and text services. Like Digital 3&4's multiplex 2, the Network Six multiplex is a highly sophisticated regionalised multiplex, with many regional variations across the UK. Each regional franchisee has control over the majority of the multiplex.

Details
There are 8 streams available on Multiplex 3. 4 (labelled A-D) are operated by Network Control, with the remaining four (labelled 1-4) to be filled by the regional broadcasters. Further streams can be created by changing bitrates of the Franchisee's half. A small amount of space is then provided for data/radio services on the Network half (labelled X), and the Franchisee's half (labelled 0).

Each regional franchisee may additionally carry regional television, text, radio or other services. The logical channel number 110 is reserved for Network Six's text services. The multiplex can have the potential capacity to carry 7-9 television streams.

Although generally the regional franchisee has control over the method of which the multiplex is broadcast, it is obligatory to carry the services listed above.
