摘要： A communications system for transmitting and receiving remote control messages in an electronic remote control system. The present communications system uses a remote control message protocol which is particularly suitable for transmitting RF remote control messages with IR remote control messages in a time multiplexed fashion, wherein the RF remote control messages are transmitted during the pause intervals between IR remote control message transmission intervals. The present remote control message protocol includes a start sequence, comprising a MARK pulse and a SPACE of about equal duration, followed by a plurality of data fields. Each data field ends with an End of Field marker and the remote control message ends with an End of Message marker. The plurality of data fields comprises an addressing data field for specifying the destination device, a security code data field for allowing a specific remote control transmitter to control a specific destination device, a status field for specifying various status codes associated with the remote control message, a keycode field for carrying the remote control message payload, and a checksum field for verifying the transmission integrity of the remote control message. A remote control message based on the present message protocol may be expanded to include additional data fields and to expand pre-existing data fields.
