1. A reception system for television comprising a plurality of tuners (2, 2′
- ) each furnished with at least one input (3, 3′
) and one output, at least one RF low signal noise converter (1) linked to an input (3) of a tuner (2) of said plurality, optionally at least one other RF low signal noise converter (1′
), and means (6) for switching the input (3′
) of at least one other tuner (2′
) of said plurality by choice over to a converter (1′
) which is not yet linked to a tuner of said plurality or over to a converter (1) already linked to a tuner (2), characterized in that it comprises means (11′
) for detecting whether the converter (1′
) not yet linked is in service or is not in service, and means suitable for actuating said switching means (6) in such a way as to link said input (3′
) of this tuner (2′
) to the not yet linked converter (1′
) when said detection means (11′
) detect that the latter is in service and to link said input (3′
) of this tuner (2′
) to the converter (1) already linked to another tuner (2) when said detection means (11′
) detect that the converter (1′
) not yet linked is not in service.

Abstract
System comprising a first converter 1 linked to a first tuner 2 and optionally, to a second tuner 2′ via switching means 6, optionally a second converter 1′ linked to the second tuner 2′ means 11 for detecting whether the second converter 1′ is in service and means suitable for actuating the switching means 6 in such a way as to link the second tuner 2′ to the second converter 1′ when one detects that the latter is in service and, in the converse case, to link it to the first converter 1.
Advantage: automatic connection of each of the tuners to at least one antenna.

4. A process for television reception with the aid of at least two tuners each connectable to corresponding means of reception, which may be placed in service or out of service independently of one another, characterized in that it comprises the steps consisting in, for at least one of the tuners,
detecting whether the means of reception corresponding to said tuner are in service, and, in the case where one detects that said means of reception are in service, connecting said tuner to these means of reception, in the case where one detects that said means of reception are not in service, connecting said tuner to other means of reception already connected to another tuner.
