ABSTRACT:
Infrared light is used in a device for wireless transmission of digital data, e.g. in headphones. In order to satisfy the strict requirements regarding compactness and power consumption, it is proposed that three digital stereo sampling values are encoded in data frames of 128-bit length for channel coding. Control characteristics and synchronizing characteristics are added to these data frames. A special coding rule is used for the sampling value coding.
