Infrared adapter with data packet throttle
View Patent ↗A method for controlling data packet flow through an infrared adapter is provided and includes receiving a data stream from an infrared device. The data stream has a first data transmission rate. Further, the rate of transmission of the data stream is modified within the infrared adapter to produce an output data stream having a second data transmission rate. Also, the output data stream is transmitted from the infrared adapter. In a particular embodiment, the first data transmission rate is different from the second data transmission rate. Particularly, the second data transmission rate is less than the first data transmission rate.
