ABSTRACT:
An infrared controller detects an infrared (IR) transceiver type by entering an IR transceiver detection mode and providing a command to another IR transceiver. The command is formatted in accordance with a first IR transceiver type. The IR controller determines whether a response to the command is received within a predetermined time period. When the response to the command is received within the predetermined time period, a first IR transceiver type is indicated. When the response to the command is not received within the predetermined time period, a second IR transceiver type is indicated.
