TV and set-top box manuals are full of words that sound technical but mean fairly simple things. We've gathered the most useful ones and explained them briefly, with no formulas, so the settings menu stops looking like a secret code.
Once you know what "signal quality" means, the bar in the menu stops being scary and starts being useful.
How this section works: each definition is in plain language and applies to reception at home. The technical standards are more complex, but this level of detail is usually enough for setting things up at home.
Broadcasting and signal
- DVB-T2
- The standard used for digital over-the-air TV in Russia. To watch it, you need a TV that supports it or a separate set-top box for an older TV.
- Multiplex
- A bundle of several TV channels transmitted together on a single frequency channel. That's why poor reception knocks out a whole group of channels at once, not just one.
- UHF band
- The frequency range used for digital over-the-air broadcasting. Antennas for digital TV are designed specifically for it.
- Transmitter
- A ground station with a tower that broadcasts the TV signal across the surrounding area. The closer it is and the fewer obstacles in between, the easier reception gets.
- Coverage area
- The area where a transmitter's or satellite's signal is strong enough for steady reception. For digital over-the-air TV, the broadcast network publishes these maps.
Equipment
- LNB
- A small unit in front of a satellite dish. It collects the signal reflected by the dish and converts it so it can travel down the cable to the receiver.
- Receiver
- A device that decodes the incoming signal and sends the picture to the TV. The term usually refers to a satellite receiver.
- Set-top box
- A compact digital over-the-air tuner for a TV that can't decode that signal on its own. It connects between the antenna and the screen.
Setup and contracts
- Auto scan
- A mode in which the TV or set-top box steps through the frequencies on its own and saves the channels it finds. Handy after a move or after repositioning the antenna.
- Signal strength
- A measure of how strong the signal is at the input. High strength on its own doesn't guarantee a good picture.
- Signal quality
- A measure of how clean the signal is and how well it can be decoded. This is the bar to go by when you're looking for the best antenna position.
- Subscription fee
- A recurring payment under a contract with a provider for access to a channel package. There's none for the mandatory free-to-air digital channels; with satellite and internet TV, it's usually part of the contract terms.
