Camera interface for television studios.

Optical Camera Interface
for Television Studios with Replay Functionality

The system consists of a studio unit (Studio Fiber Module) and several camera units (Camera Fiber Modules). In its basic configuration, the studio unit supports operation with 3 camera units (expandable to up to 6 camera units in the extended configuration).

The system provides a bidirectional optical connection between the camera units and the studio unit, allowing it to be used when the distance between the camera and the studio is too great for SDI signal transmission over standard coaxial cable. It also enables the transmission of camera signals to the studio while simultaneously supporting return video (e.g., for a teleprompter system), genlock synchronization, PTZ camera control, and Tally signal transmission (to control an LED indicator mounted on the camera).

System Features:

• Transmission of up to 6 video signals from cameras to the studio unit over inexpensive optical cable across long distances (and further to a video switcher via SDI interface);

• Transmission of PTZ camera control signals and remote adjustment of camera settings;

• Return video feed to the camera (for teleprompter systems);

• Support for Tally signal transmission (to control an LED indicator mounted on the camera);

• Replay functionality (implemented via SSD storage in the camera units, which continuously records the incoming signal in DAVC format—frame-by-frame compression with low ratio—and allows for playback of selected segments in slow or fast motion as needed).
