FIELD: radio engineering and communications.
SUBSTANCE: invention relates to communication engineering and can be used in a wireless computer, which forms a pair with the remote audio-video device, such as TV set. That is a communication channel is installed, so that computer transmits audio-video content for display through the above mentioned device. As a part of pair forming, computer and remote device select side channel for transferring user commands. Wireless computer can display the user interface, through which the user can enter commands controlling manner, in which remote audio-video device gives content. As a result, the user can use wireless computer as a remote control of audio-video device, controlling both given content and manner in which it is presented. Side channel can use other frequencies than channel used for transferring audio-video content.
EFFECT: technical result consists in using very low power at frequencies in the spectrum of digital television.
