Introduction
The Sierra Video multi-viewer enables up to 64 channels of video to be viewed on a single
display device. However, each multi-viewer has a pair of DVI-I outputs that may be independently
configured if required. The video inputs are auto-sensing for composite/S-Video/YUV/RGB/DVI-
I/SDI/HD-SDI sources. Multi-definition standards up to 3G 1080p are supported. Comprehensive
alarm functions, audio metering and monitoring capabilities are also incorporated.
The Sierra View is designed to optimize monitoring flexibility within the multi-channel video
environment, including video production, television broadcast, CCTV, medical, aerospace,
exhibition and conference applications. It is supplied in either single or dual multi-viewer
configurations as a 3U rack mounting frame. Options include an external backup power supply
(POWER-xx) and remote control panel (SV-Remote). The SV is easily controlled from a PC web
browser hosted by the frame itself, either directly via an Ethernet cable or over a network.
The SV can also be used as a multi-channel audio matrix, de-embedder and analog to AES/EBU
digital cross converter, depending on the I/O cards fitted.
Any combination of inputs can be used. The maximum number of audio outputs is 196 channels
(using 6 x output boards). Any input may be routed to single or multiple outputs.
System concept
The modular architecture is designed for scalability. Of the two 3U frame types available, the
single multi-viewer frame, is equipped with one controller (CPU) and one power supply module
(PSU). The dual multi-viewer frame is centrally divided and capable of housing two separate
multi-viewers, each with its own CPU and PSU modules.
Each video input card handles 4 sources. The single frame will accommodate up to 16 video
cards, providing a maximum capacity of 64 video channels. The dual frame provides a maximum
capacity of 32 video channels for each multi-viewer (8 video cards per side). The video cards
include support for SDI embedded audio. If external audio interfacing is required, audio input or
output cards may be fitted. These will reduce the capacity available for video cards.
For maximum flexibility, separate rear connector modules provide a variety of possibilities,
including fiber interfacing for video cards.
The video input cards will simultaneously support sources of differing rate, for example, 50Hz and
60Hz. However, synchronisation is achieved by frame add and drop rather than standards
conversion. The system rate is either locked to the reference signal provided or a designated
video input source.
