TV receiving installation, e.g. within hotel with own programme facility

摘要

The radio wave receiving system, particularly a TV system, has at least one sound and/or image station and an antenna main station coupled to this station to receive HF radio signals corresponding to radio programmes. At least one coding unit is provided in the antenna station. This provides the radio signal of at least part of the received programme with a coding. The sound and/or image station includes a code detector, consisting of a separator (37) and a microprocessor (38). This recognises the coding and only relays radio signals with this coding to the next image and/or sound generating component of the sound and/or image station.
