Abstract
A paid broadcast receiving device has a decoder connection detector for determining whether or not a video cassette recorder (VCR) and a canal+ decoder are connected. The determination depends on an impedance match between the VCR and decoder when a canal+ broadcast channel is selected after the canal+ channel is stored in a system where a VCR is to be connected to a canal+ decoder and a television. The system thereby receives and/or records canal+ broadcasts without a decoder, for paid broadcasts sent via a public line, even if the canal+ decoder is not connected to the VCR. Users are able to easily judge whether or not the canal+ decoder is connected.
