What Does LCN Mean On A Freeview Box?
Have you ever had this message on your TV screen? “LCN has changed”? Do you know what it means? Would you like to know what it means? Read on to find out what it means and how to get rid of it.
What Do The Letters LCN Mean?
If you’ve ever had “LCN has changed” message come up on your Freeview screen you probably wonder what it means. The letters LCN stand for Logical Channel Numbering. It is basically the number allocated to each channel by the Freeview box. For instance
- BBC1 – channel 1
- BBC 2 – channel 2
- ITV 1 – channel 3
And so on. When duplicate LCNs are found during a scan or retune, the one with the strongest signal will be allocated the LCN.
What Is Logical Channel Numbering?
Logical channel numbers are numbers allocated to channels by the Freeview box to make the channels easier to identify for the user. For instance BBC1 and ITV1 are both channel 1 but that’s not logical as you can only have 1 number 1. So they assign each channel with a number that makes sense, the LCN numbers can go as high as 3 digits, so some channels will be in the 100s. Usually the HD channels use the same numbering as the regular digital channels apart from starting at 100. So:
- BBC1 HD – 101
- BBC2 HD – 102
- ITV1 HD – 103
And so on.
