Abstract

A system for at least substantially plesiochronously operating a receiver in communication with a plurality of cameras (e.g., at least two plesiochronously operational cameras) is described. In one or more implementations, the system includes a plurality of cameras. Each camera is configured to generate a signal for transmission via a communications link, and the signal comprises data packets encoded in a forward channel. The system also includes a receiver communicatively coupled to the plurality of cameras via the single-ended communications link. The receiver is configured to generate a synchronization data based upon at least one of the data packets. The receiver is also configured to modulate the signal to encode the synchronization data in a reverse channel so that the signal comprises the forward channel data and the reverse channel data simultaneously.

Dependent claims

A system comprising:

a plurality of cameras, each camera of the plurality of cameras including a respective camera communication interface configured to generate a signal for transmission via a physical single-ended communications link, the signal comprising serial data packets encoded in a forward channel;
and
a receiver communicatively coupled to the plurality of cameras via the physical single-ended communications link, the receiver configured to generate a synchronization data based upon at least one of the data packets, the receiver including a plurality of receiver communication interfaces, each respective receiver communication interface configured to convert serial data packets from a corresponding camera to data in a suitable format for the receiver, each respective receiver communication interface configured to modulate the signal received from a respective camera of the plurality of cameras to encode the synchronization data in a reverse channel so that the signal comprises the forward channel data and the reverse channel data simultaneously over the same physical single-ended communications link.

Dependencies are inferred from the claim text.
