Abstract

Method and device for establishing two-way wireless communication between two audio and / or video devices (4,8) arranged in different rooms (2,3) of a building (1). The first of the two audio and / or video devices includes a source of audio and / or video electrical signals capable of being controlled by remote control signals, the second of the two audio and / or video devices includes a receiver and generates electrical signals that cannot pass through the building A remote control for remote control signals from the walls of objects, one of the relays sends remote control information to other relays via a radio link, which can return audio and / or video signals from the source to the relay via a radio link, the encoder is arranged to insert a code in the remote control message, and a decoder is used to decode the coded remote control message received by the relay, which compares the code included in the coded remote control message with a reference code, and if between the two codes Inconsistent, refuse to decode the remote control information.

Description

technical field [0001] The present invention relates to a wireless interconnection method for establishing two-way communication between two audio and / or video devices located in different rooms of a building, and a wireless interconnection device for implementing this method. Background technique [0002] A user often has several audio and / or video devices installed in different rooms of his residence, for example a primary audio and / or video device installed in a living room and secondary audio and / or video devices installed in other rooms such as a bedroom . The primary audio and / or video unit may have a first receiver, such as a television receiver, and at least one source of audio and / or video electrical signals, such as a cable TV channel decoder, satellite TV decoder, pay TV decoder , video tape recorders, digital video disc (DVD) players, hi-fi combos, audio cassette players, compact disc players, etc. The secondary audio and / or video device comprises a second rece...
