20030112338, Jun 19, 2003

Filed:

Dec 17, 2001

Appl. No.:

10/023452

Inventors:

David Pelletier - Southbridge MA, US
Eugene Baker - Worcester MA, US
James Hurwitz - Mill Valley CA, US

Assignee:

Telecast Fiber Systems, Inc. - Worcester MA

International Classification:

H04N005/232

US Classification:

348/211990

Abstract:

A system includes a multiplexing transceiver which is adapted to mount directly between a video camera and a camera battery pack, eliminating the need for triaxial adapters or other electrical cables at the camera and video production facility. A fiber optic cable carries upstream and downstream television signals between the camera-mountable transceiver and a remote base station transceiver. The camera-mountable transceiver includes a transmitter adapted for converting an electrical information input signal received from the camera to an optical output signal. The transceiver further includes a receiver adapted for converting an optical input signal received from the fiber optic cable to an electrical information output signal. A transceiver housing includes a first plate on a first side for mounting the housing to the camera and a second plate on a second side for mounting the housing to a power source.

Assignee:

MIRANDA TECHNOLOGIES PARTNERSHIP - Montreal

International Classification:

H04B 10/25

US Classification:

398 79, 398141, 398142, 398 98

Abstract:

A system and method for carrying a downstream optical signal and an upstream optical signal on a fiber optic link is disclosed. The system and method includes a first transceiver unit that receives an input communication signal from at least one external communication device at an electrical input port, a transmitter that converts the input communication signal into an optical signal and transmits the optical signal as an downstream optical signal on a fiber optic link, a receiver at the second transceiver unit that receives the downstream optical signal and converts the downstream optical signal into an electrical communication signal, and a first circuit in the second transceiver unit that determines whether the second transceiver couples the electrical communication signal to a two wire intercom circuit or a four wire intercom circuit.
