It is an object of the present invention to provide a transceiving method which allows both higher-rate communication and reception of data with reduced current consumption. An infrared transceiver according to the present invention includes an infrared transceiver module (2) that receives signals by switching between a low-rate reception mode and a high-rate reception mode with a higher reception rate than the first reception mode, and a microcomputer (3) which, upon reception of a signal of a second signal form, controls the switching of the infrared transceiver module (2) from the first reception mode to the second reception mode, and allows commencement of the reception of a signal of a first signal form. The signal of the first signal form consists of data containing various information, and the signal of a second signal form is a guide pulse that is used to start the reception of the signal of a first signal form.
L'invention porte sur un procédé d'émission/réception permettant à la fois la communications et la réception de données à très fort débit avec une consommation de courant réduite, et sur un appareil comprenant: un émetteur/récepteur IR (2) recevant des signaux et pouvant commuter entre un premier mode de réception à faible débit et un deuxième mode réception à fort débit plus important que le premier; et un micro-ordinateur (3) qui au reçu d'un signal de la deuxième nature commande la commutation de l'émetteur/récepteur IR (2) du premier mode dans le deuxième, tout en autorisant le début de la réception d'un signal de la première nature. Le signal de la première nature consiste en données contenant différentes informations, et le signal de la deuxième nature consiste en une impulsion pilote commandant le début de la réception du signal de la première nature.
