Abstract

Priority switch for solving collision problems with signalling on a bus The invention relates to a priority switch for managing the control signalling on a common control signal bus between at least two control signal source devices and a control signal destination device. The priority switch comprises monitoring means for monitoring which of the source devices intends to send control signals towards the destination device; prioritising means, connected to said monitoring means, for prioritising one of the control signal sources among those which intend to send control signals, over the others, switching means, connected to said prioritising means, for connecting the prioritised source device through to the common control signal bus, and busy signal generating means, connected to said prioritising means, for informing the other source devices that the common control signal bus is occupied. The invention further relates to an RF/IF signal handling device incorporating the priority switch and a corresponding method for managing the control signalling on a common control signal bus. The control signals can be based on the DiSEqC protocol, the destination device can be a satellite channel router, source devices could be satellite receivers.
