Abstract
Techniques and examples pertaining to single channel line-of-sight (LOS) communication are described. The transmitting end of the LOS communication involves direct modulation of a light emitted from a light emitter. The receiving end of the LOS communication involves receiving a video stream of the light emitter emitting the light, wherein the video stream comprises a plurality of video frames that are continuous in time. The receiving end of the LOS communication also involves converting the video stream to a binary string comprising a plurality of binary bits. Each of the binary bits corresponds to a respective one of the plurality of video frames, and the binary string contains a repeated binary pattern representing a message being conveyed. The receiving end of the LOS communication also involves extracting the binary pattern from the binary string and then decoding the binary pattern to obtain the message.
