Automatic detection of infrared extender or blaster

摘要

A method for automatically detecting an infrared blaster or an infrared receiver includes detecting receipt of an infrared device by a media device. The media device has an internal infrared receiver and a processor. The method further includes determining if the infrared device is an infrared extender or an infrared blaster. When the infrared device is an infrared extender, the method includes disabling the internal infrared receiver and connecting the infrared device to the processor of the media device. When the infrared device is an infrared blaster, the method includes connecting the infrared device to the processor of the media device and not disabling the internal infrared receiver.

1. A method for automatically detecting an infrared blaster or an infrared extender, the method comprising:
detecting receipt of an infrared device by a media device when a socket of the media device receives a connector of the infrared device, the media device having an internal infrared receiver and a processor; and determining whether the infrared device is an infrared extender or an infrared blaster by detecting a logic high or a logic low on an electrical connection of the socket of the media device by the received connector of the infrared device; wherein when the logic high on the electrical connection of the socket of the media device is detected:
determining that the infrared device is the infrared extender;disabling the internal infrared receiver; andconnecting the infrared device to the processor of the media device; and wherein when the logic low on the electrical connection of the socket of the media device is detected:
determining that the infrared device is the infrared blaster; andconnecting the infrared device to the processor of the media device and not disabling the internal infrared receiver.
