Patent ID: 7421208

Claim:
Method for infrared data transmission comprising the steps of: (a) providing an infrared data transmission system comprising a plurality of transmitter units and a common receiver station; and (b) transmitting a plurality of data blocks via said plurality of transmitter units with a common carrier frequency, wherein each data block of said plurality of data blocks is repeatedly transmitted a number of times in a transmission interval from a respective transmitter unit of said plurality of transmitter units, the number of times being equal to a total number of said plurality of transmitter units, the transmission interval includes a plurality of repetition intervals for transmission of the data blocks, each repetition interval having a duration equal to the time of the respective transmitter unit that is between beginnings of two transmissions of the data block that follow one another, each repetition interval duration for the respective transmitter unit differs from every other repetition interval duration of the other transmitter units by at least twice a transmission time of a maximum data block, a shortest repetition interval of said plurality of repetition intervals corresponds at least to a multiple of double the transmission time for the maximum data block size, said multiple corresponding to the total number of said plurality of transmitter units, the transmission interval of each transmitter unit of said plurality of transmitter units is equal in duration, and said transmission interval ends after a last transmission of the data block of the transmitter unit with a longest repetition interval of said plurality of repetition interval ends plus the transmission time of a maximum data block plus the duration of the shortest repetition interval.
