Abstract
A protocol for transmitting data from an external device to an electronic device is provided in which the external device transmits a data stream which includes the same data packet repeated multiple times. The data packet has a predetermined length and has a header portion at a predetermined position. A receiver at the electronic device captures a block of data having the predetermined length from the transmitted data stream, and a decoder rotates the captured block of data to place the header portion at the predetermined position within the data packet. This eliminates the need for an accurate jitter-free clock reference at the electronic device. By shifting power consumption and system complexity to the external unit where power is typically not constrained, the energy efficiency of the electronic device can be increased.
