Abstract

A remote-control-signal receiving device includes a plurality of signal receiving parts for receiving remote-control signals, a plurality of decoders for decoding the remote-control signals received by the plurality of signal receiving parts, and a signal processing part for determining the reliability of data outputted from the plurality of decoders on the basis of the data.

Claims

1. A remote-control-signal receiving device comprising:

a plurality of signal receiving means for receiving remote-control command signals;

a plurality of decoding means for decoding the remote-control command signals received respectively by said plurality of signal receiving means;

a control means having a memory storing a program of a process which is executed by said control means; and

processing means controlled by said control means to execute the process based on the program for selecting a remote-control command having the highest priority or the highest reliability in the plurality of the remote-control commands decoded by the plurality of said decoding means in the case that the plurality of said signal receiving means received respectively the plurality of the remote-control command signals at about same time, wherein said processing means validates a selected remote-control command having the highest priority or the highest reliability and invalidates non-selected remote-control commands when the process is executed by said processing means.

2. A remote-control-signal receiving device according to claim 1, wherein said plurality of decoding means, said control means and said processing means are contained in one microcomputer.

3. A remote-control-signal receiving device according to claim 1, wherein said processing means for selecting the remote-control command having the highest priority or highest reliability in the plurality of the remote-control commands decoded by the plurality of said decoding means in accordance with definitions described in the program.

4. A remote-control-signal receiving device according to claim 3, wherein said processing means for selecting the remote-control command having the highest priority in the plurality of the remote-control commands decoded by the plurality of said decoding means according to the types of the remote-control commands.

5. A remote-control-signal receiving device according to claim 3, wherein said processing means for selecting the remote-control command having the highest reliability in the plurality of the remote-control commands decoded by the plurality of said decoding means according to a number of times which received the remote-control commands by each signal receiving means.

6. A remote-control-signal receiving device according to claim 3, wherein said processing means for selecting the remote-control command having the highest priority or highest reliability in the plurality of the remote-control commands decoded by the plurality of said decoding means according to receiving status of said signal receiving means.

7. A remote-control-signal receiving device according to claim 1, wherein said processing means invalidates all of the remote-control commands when said processing means cannot discriminate the remote control command having the highest priority or the highest reliability.

8. A remote-control-signal processing method comprising the steps of

a signal receiving step of receiving remote-control command signals by a plurality of signal receiving means;

a decoding step of individually decoding the plurality of remote-control command signals received in said receiving step; and

a signal processing step of executing a selection for a remote-control command having the highest priority or the highest reliability in the plurality of the remote-control commands decoded in said decoding step in the case that the plurality of said signal receiving means received respectively the plurality of the remote-control command signals at about same time, wherein said signal processing step of validating a selected remote-control command having the highest priority or the highest reliability and invalidating non-selected remote-control commands when the selection of the remote-control command is executed.

9. A remote control signal processing method according to claim 8, wherein the signal processing step of invalidating all of the remote-control commands when the remote-control command having the highest priority or the highest reliability is not discriminated.

10. A recording medium on which stores a program for executing the processes comprising:

a signal receiving step of receiving remote-control command signals by a plurality of signal receiving means;

a decoding step of individually decoding the plurality of remote-control command signals received in said receiving step; and

a signal processing step of executing a selection for a remote-control command having the highest priority or the highest reliability in the plurality of the remote-control commands decoded in said decoding step in the case that the plurality of said signal receiving means received respectively the plurality of the remote-control command signals at about same time, wherein said signal processing step of validating a selected remote-control command having the highest priority or the highest reliability and invalidating non-selected remote-control commands when the selection of the remote-control command is executed.

11. A recording medium according to claim 10, wherein the signal processing step of invalidating all of the remote control commands when the remote-control command having the highest priority or the highest reliability is not discriminated.
