A system for transmitting optical communications includes a transmitter, a receiver, and a processor. The transmitter includes a light source driven by a driver circuit under control of a micro-controller to transmit an optical signal. The optical signal can be encoded by a frequency-modulated encoding scheme. The receiver includes an optical lens, an imaging sensor configured to receive the optical signal and a memory. The processor is configured to extract one or more frequencies from the optical signal for only those pixels that are changing and thus decreases an overall data rate for the system and allows for larger pixel arrays, thereby decreasing the accuracy requirements of any pointing hardware and to reconstruct a waveform for each of the extracted frequencies.

Systems and methods for redundant storage among networked video cameras are described. Video data for a group of video cameras is received by a parity video camera. The parity video camera calculates parity across the peer video data, stores the parity data to one storage location and backup video data for the storage location to another storage location. In some examples, the storage locations are selected from among the non-volatile memory of the group of video cameras or another group of video cameras.

Systems and methods are presented herein that facilitate temporally synchronizing, in real time, a separately sourced high quality audio segment of a live event with a video segment that is generated by a recording device associated with a member of the audience. An A-V Synchronization Application may synchronize a video segment of a live event that is generated from a personal electronic device of an audience member with a high quality audio segment that is separately sourced and generated by professional sound recording equipment at the live event. The result of the temporal synchronization is a high fidelity digital audio visual recording of the live event. In various, the audience member may stream, in real-time, the high fidelity digital audio visual recording to an additional electronic device at a different geo-location. In some examples, narrative audio segments may be also included as part of the high fidelity digital audio visual recording.
