These versions interconnect using one strand of single-mode fibre-optic cable (not included) and provide support for the following:
•
Digital Video: one 3G/HD/SD-SDI send (camera to truck) and one 3G/HD/SD-SDI return (truck to camera)
•
Line/IFB: two analog line-level audio returns (truck to camera) and one 2-channel IFB output (camera) with 28 V beltpack power
•
Intercom: integrated 2-channel system with party-line on all Camera End and Truck End units; single-channel 4-wire interface on Truck End Rack-Mount units
•
Powering: Camera End and Truck End Portable powered by 10-18 Vdc or battery; standard version of Truck End Rack-Mount unit powered by 12 Vdc; advanced version of Truck End Rack-Mount unit powered by 100-240 V, 50/60 Hz or 10-18 Vdc
•
Embed Outputs: Truck End Portable provides two analog outputs de-embedded from SDI group 1 audio; advanced version of Truck End Rack-Mount unit provides four analog outputs de-embedded from SDI group 1 audio
Camera End and Truck End Portable units include enclosure with Anton/Bauer battery mount system (contact factory for V-Mount availability), handle, and rubber feet. The standard and advanced versions of Truck End Rack-Mount units mount in one space (1U) of a standard 19-inch equipment rack. All units each use one ST fibre-optic connector. Camera End, Truck End Portable, and standard version of Truck End Rack-Mount unit also includes a universal input (100-240 V, 50/60 Hz)/12 Vdc output power supply.
Video Transport
Live-Link Mini transports two SDI video signals, one going from the camera end to the truck end and the other from the truck end to the camera end. 3G-, HD-, and SD-SDI signals at a wide range of formats and rates are supported. On the front panel of the camera end unit a BNC connector provides the "return" SDI signal. At the truck end units the SDI signal originating at the camera end is provided as two independent, buffered SDI outputs.
Optical Transport
The camera end unit interconnects with its associated truck end unit using one strand of single-mode optical fibre. Two optical wavelengths, one traveling in each direction, are used for signal transport. All video, audio, and control data is multiplexed (combined) as part of a single industry-standard SDI signal. One ST optical connector is provided on each unit. This connector type was selected because of its low cost and wide acceptance. It's routine to find ST connectors terminated on the "house fibre" that's present in many sports stadiums, education facilities, and convention centres. It's also common for mobile broadcast and field-production applications to utilize ST-terminated tactical-grade TAC-4 or TAC-12 multi-strand fibre assemblies.
Three Truck End Units Available
To meet the needs of specific applications three Live-Link Mini truck end units are available. Two of the versions mount in one space (1U) of a standard 19-inch equipment rack. The third version is portable and matches the form-factor (style) of the camera end unit.
The two rack-mount truck end versions differ in their powering and audio de-embedding capabilities. The standard rack-mount version is powered by 12 Vdc and relies on its SDI outputs to provide embedded audio to the connected equipment. This is the most cost-effective version and meets the needs of "all embedded" applications where audio is always transported along with picture information. The advanced version of the rack-mount truck end unit offers flexibility in powering and adds four de-embed audio outputs. A source of 100-240 V, 50/60 Hz can be connected to power the unit. Alternately, a 12 Vdc source can be connected. Some applications may benefit from having analog outputs associated with the audio channels embedded by a connected camera, camcorder, or other video source. The advanced rack-mount version de-embeds the four channels associated with group 1, converts them to analog, and presents them on four balanced line-level outputs.
The standard and advanced rack-mount truck end versions provide support for both party-line (PL) and 4-wire intercom systems. This allows integration into a large range of professional intercom scenarios. Dual-channel party-line user beltpacks can be directly connected and powered. Alternately, an existing party-line intercom circuit can be directly connected, with the Mini unit just acting as another user device. The single-channel 4-wire intercom interface allows connection to a local or remotely-located matrix intercom system.
