Title:
【発明の名称】再構成可能遠隔制御装置
Document Type and Number:
Japanese Patent JP2612056
Kind Code:
B2
Abstract:
A reconfigurable remote control apparatus and method for capturing the signals of transmission devices of at least two different protocols are provided. Because transmission devices either output signal bursts of different lengths at a carrier frequency followed by pauses of different lengths, or pulses of a relatively constant length followed by pauses of different lengths, a first determination is made as to the type of system being captured. After the system type is determined, the carrier frequency and the burst and pause lengths are determined for a burst type system, while only the pause lengths are determined for a pulse-pause type system. The captured information is preferably compressed according to a preferred compression schema which finds and stores all possible signal lengths and all permitted adjacent signal length combinations for a particular apparatus, and composes and stores a compressed code which acts as a ponter to the stored signal length combinations. A further aspect of the invention is that a user need only press the keys of the remote unit to be captured during the capturing sequence and is prompted to do so by the apparatus of the invention.
