The CPU card, Buffer card and PSU module are located in fixed positions within both the
single (MV-64) and dual (MV-32) multiviewer frames. A CPU card will always be fitted to slot 1
and a buffer card in slot 2. A dual frame MV-32 multiviewer will additionally have a CPU card
fitted in slot 11 and a buffer card in slot 12.
Video and audio cards are installed in the remaining slots in sequence, from right to left, as
viewed from the front.
3.4.1 Video Inputs
Separate rear connector modules of the required type are fitted to allow interfacing with each
input card. These are available with different combinations of BNC and Microcross DVI-I
connectors to suit the application. A single BNC connector is used for formats such as
SD-SDI, HD-SDI and *Composite video. For S-Video, two BNC connectors are required, for
RGB/YUV three BNC connectors are required.
Most video input card connector modules are also equipped with an 8 x GPI port, although in
some instances, insufficient space is available.
3.4.2 Video Outputs
The two DVI-I display outputs (per multiviewer) support resolutions up to HD 1080p60, 16:9
(1920 x 1080). Both digital and analog outputs are available on these connectors. Tiles
displayed via the outputs can be varied continuously in size and position, cropped or
displayed in pre-configured screen layouts on a chosen colored background. The pair of
outputs may either be set to provide two identical display configurations, or they may have
differing arrangements.
3.4.3 Audio I/O
Audio levels may be displayed using up to 16 bargraphs in each tile (32 bargraphs per tile
with MV-VIP3D cards), either superimposed on each video image or outside active video.
Audio is derived from the incoming embedded audio (when using SD-SDI or HD-SDI inputs),
or from external sources, for which the appropriate audio input card option must be installed.
Optional audio output cards (32 channels analog or 16 AES/EBU pairs) may be fitted to
provide demuxed outputs from embedded audio.
Audio input and output cards must be fitted in conjunction with the appropriate rear connector
modules.
There is an 8 channel analog audio monitor output, which may be assigned from any input
channel of any format, excluding incoming external audio level data.
All bargraph scales and ballistics conform to international standards and include BBC PPM,
DIN PPM, Nordic PPM, VU, extended VU, and AES/EBU digital.
Note:
The I/O cards are not hot-swappable and the multiviewer must be powered down when
inserting and removing cards.
Note:
•
Component and DVI inputs are not supported by the MV-VIP3 and MV-VIP3D
cards.
•
*Only inputs 1 and 2 can be used for Composite video on MV-VIP3 and MV-VIP3D
cards.
Note:
The number of audio channels described always refers to individual channels, not channel
pairs. For example, eight monitor outputs relate to eight individual analog channels or 4
pairs AES/EBU channels.
