What is lcn on tv

The current level of development of electronic devices, in particular televisions, provides users with a lot of possibilities to adjust them to their preferences. Many viewers choose for themselves from the entire set of channels the ten most watched, ranking according to their "rating". Therefore, the sorting of channels is very important so as not to remember the digital code of each of them, and at the beginning of advertising, for example, switch to the next with the click of a button.

What is lcn on tv

Each provider of digital television services in the transmitted signal assigns four-digit serial numbers to the channels. Therefore, the default channel order for all subscribers is identical. When searching for TVs and set-top boxes of digital TV (DVB, T2), they are ordered by the ascending order of these numbers, which are called LCN.

LCN (Logical Channel Numbеr) translates as logical channel number. Since the beginning of 2012, Roskomnadzor has been trying to regulate TV channels, but given that in Russia there are about 2,000 TV providers and more than 300 channels (including regional, regional), it is practically impossible to implement this. Note that content providers themselves also claim to be “convenient” LCNs - for example, TNT requires that all providers receive 11 LCNs, but most of them are already occupied, and reconfiguring the equipment is extremely costly.

REFERENCE! Providers put the LCN sequence in their view of the rating, and a hard fixation of numbers does not make sense - users, as a rule, adjust the order of TV channels for themselves, and the popularity of channels in different regions varies greatly.

Features of using lcn in a TV

The menus on TVs of different brands are different, so to work with LCN you need to find the appropriate item. In many models, manual shutdown is not required, the order is changed simply by "moving" in the setup mode with the CH + and CH- buttons. Sometimes you need to disable it manually to set the user order, or, conversely, set it to default.

For clarity, we show how the desired menu item might look:

ATTENTION! By enabling LCN again, the user loses the previously established order.

Note that in this section of the menu you can specify other types of sorting, for example, alphabetically.

So, we see that LCN is just the recommended service order for following channels, and adjusting the TV for yourself is available to any viewer - you just need to explore the menu options or read the instructions.
