What is LCN option on my TV and what is it used for?

Logical Channel Numbers (LCNs) are unique channel numbers assigned to each TV station and will serve as a unique identifier on the digital broadcasting platform. LCNs are user friendly and convenient, that is the numbers are arranged in a logical manner that is easy for viewers to remember.

With LCN ‘On’  The Channel listing will be numbered in a logical order where the main channels such as 1, 2, 3, 4, 5 etc  will be BBC, BBC2 ITV Channel 4, Channel 5 where there is a sufficient signal.  This makes it easier for the user to navigate to the channel using the numeric keypad on the remote if they know the Channel Number.
