Abstract

When the HPD (104b) which indicated that the transmission of a control signal between the data receiving apparatus (102) and the control signal receiving apparatus (101) has become possible is detected, the command judging section (115) ignores the first reception command which it directly received from the remote controller (103) and makes the second reception command (112a) effective which it receives via the CEC line (104a). In such a construction, it is possible to conduct a remote control operation normally without affecting unfavorable influences on the apparatuses.

Claims

1. A control signal receiving apparatus which can receive a control signal from the remote control unit which is attached to the control signal receiving apparatus via a data receiving apparatus which is connected to the control signal receiving apparatus, comprising:

a command judging section which receives a first reception command which is directly received from the remote control unit and a second reception command which is received via the data receiving apparatus as its inputs and outputs selectively either command with judging one which is to serve as effective.

2. A control signal receiving apparatus as defined in claim 1, wherein,

the command judging section makes the second reception command which is received by the apparatus later effective when the first reception command and the second reception command are received by the apparatus temporary close to each other.

3. A control signal receiving apparatus as defined in claim 2 wherein,

there is provided a connection signal detection section which detects a connection signal which indicates that the transmission of the control signal between the data receiving apparatus and the control signal receiving apparatus is possible, and

the command judging section makes the second reception command which is inputted to the command judging section pass through as it is with ignoring the first reception command which is inputted to the command judging section, when it receives the connection signal which is outputted from the connection signal detection section.

4. A control signal receiving apparatus as defined in claim 3, wherein,

the command judging section cancels the ignoring of the first reception command to make the first reception command effective, when no second reception command is inputted even after a predetermined time has passed after the first reception command was ignored.

5. A control signal receiving apparatus as defined in claim 2, wherein,

there is provided a delaying section which delays the first reception command so that the second reception command and the first reception command are inputted to the command judging section in this order, and

the command judging section makes the second reception command which is inputted to the command judging section prior to the first reception command pass through as it is, and ignores the first reception command which is inputted to the command judging section later than the second reception command with being delayed by the delaying section.

6. A control signal receiving apparatus as defined in claim 5, wherein,

the command judging section makes the first reception command which is inputted via the delaying section pass through as it is, when the second reception command is not inputted.

7. A control signal receiving apparatus as defined in claim 2, wherein there are provided,

a connection signal detection section which detects a connection signal indicating that transmission between the control signal receiving apparatus and the data receiving apparatus is possible, and

a delaying section which delays the first reception command so that the second reception command and the first reception command are inputted in this order to the command judging section, and

the command judging section

makes the first reception command inputted thereto without passing through the delaying section and makes the inputted first reception command pass through as it is, when the connection signal is not detected by the connection signal detection section, and

makes the second reception command which is inputted thereto prior to the first reception command, pass through as it is, and ignores the first reception command which is delayed by the delaying section to be inputted thereto later than the second reception command, when the connection signal is detected by the connection signal detecting section.

8. A control signal receiving apparatus as defined in claim 7, wherein,

the command judging section makes the first reception command which is inputted via the delaying section pass through as it is, when the connection signal is detected by the connection signal detecting section and no second reception signal is inputted thereto.

9. A control signal receiving apparatus as defined in claim 5, wherein,

the delay amount of the first reception command which is delayed by the delaying section is larger than the time difference between the time when the first reception command is inputted to the command judging section without passing through the delaying section and the time when the second reception command is inputted to the command judging section, and is smaller than the shortest time from the time when the first reception command is inputted thereto up to the time when the next command is inputted thereto.

10. A control signal receiving apparatus as defined in claim 1, wherein,

there is provided a command comparing section which receives the first reception command and the second reception command which are received temporary close to each other as its inputs, and compares whether the first reception command and the second reception command coincide with each other, and

the command judging section makes the second reception command as effective and ignores the first reception command, when the first reception command and the second reception command are judged as coinciding with each other by the command comparing section, and

the command judging section makes the both reception commands as effective and first outputs the first reception command and subsequently outputs the second reception command, when the first reception command and the second reception command do not coincide with each other.

11. A control signal receiving apparatus as defined in claim 6, wherein,

the delay amount of the first reception command which is delayed by the delaying section is larger than the time difference between the time when the first reception command is inputted to the command judging section without passing through the delaying section and the time when the second reception command is inputted to the command judging section, and is smaller than the shortest time from the time when the first reception command is inputted thereto up to the time when the next command is inputted thereto.

12. A control signal receiving apparatus as defined in claim 7, wherein,

the delay amount of the first reception command which is delayed by the delaying section is larger than the time difference between the time when the first reception command is inputted to the command judging section without passing through the delaying section and the time when the second reception command is inputted to the command judging section, and is smaller than the shortest time from the time when the first reception command is inputted thereto up to the time when the next command is inputted thereto.

13. A control signal receiving apparatus as defined in claim 8, wherein,

the delay amount of the first reception command which is delayed by the delaying section is larger than the time difference between the time when the first reception command is inputted to the command judging section without passing through the delaying section and the time when the second reception command is inputted to the command judging section, and is smaller than the shortest time from the time when the first reception command is inputted thereto up to the time when the next command is inputted thereto.
