The CNI sign indicating number of Britain TV channel transmits transmission in PDC (Programme Delivery Control) mode according to 8/30format1 or 8/30format2, and particular content can be consulted the related art file.

Britain's program ordering requirements is:

1 channel: BBC1

2 channels: BBC2

3 channels: ITV

4 channels: CH4

5 channels: CH5

Preceding 4 channel states all over Britain generally have, and CH5 some areas do not have.In the Britain different regions and the different period, program may be different.May be different as Scottish BBC1 and English BBC1, at 7 in England morning and afternoon, 7 BBC1 was possible different.The difference here is National and Regional channel.

In the automatic channel search process of the inventive method, when searching out channel program, at first read its CNI sign indicating number, in 8/30format1 and 8/30format2 CNI code table, search simultaneously, judge whether this channel belongs to BBC1, BBC2, ITV, CH4 and CH5.If belong to, then this channel is stored under the specified channel number; If do not belong to, then, press the frequency sequential storage by channel 6 beginnings.After finishing automatic channel search, if the free platform of preceding 1-4 channel, then skip falls this channel.If CH5 is not searched out, then channel 6 later whole channels are made progress along moving one.The up-to-date code table of CNI is provided by the television set purchaser of corresponding region, and example is as shown in the table:
