User Manual
MV-8 Series Multiviewer Architecture
The MV-8 Series Multiviewer is found in the MV-8x0/8x1/8x5 Multiviewer range, which
covers a multiplicity of products, including multiviewers that are integrated into routers, in
standalone boxes, and/or have video IP input capabilities. Figure 1-2 and Figure 1-3 identify
the MV-8 Series Multiviewer “engines”found in some MV-8x0/8x1/8x5 Multiviewer
functional block diagrams. And Figure 1-4 gives a core multiviewer block diagram.

MV-8 Series Multiviewer
User Manual
Figure 1-4 shows a simplified block diagram of the MV-8 Series Core Multiviewer. The main
inputs and outputs of the MV-8 Series Multiviewer come from or go to the MV-8xx product
and comprise:
•48VideoInputs.
• Video Reference Timing.
• Up to 12 Multiviewer Head Display Outputs.
• Control and Monitoring.
Each video input is processed and then re-sized. There is one re-sizer (scaler) per input.
Each multiviewer head display image is composited from re-sized video images, rendered
graphical images and text.
Note: Each one of the 48 re-sized (scaled) inputs may appear any number of
times on any head display output but with the same re-sizing.

Core Multiviewer Overview
Input Processing
Input Processing
Each video input undergoes the same processing. Processing includes:
• Status.
• HDR input support.
• Media biometrics.
Additionally, a copy of each video input can be sent to an H.264 scaler/encoder on the MV-
8xx product and H.264-encoded, scaled-down copies of the video inputs are available as
video streams.
HDR Input Support
The MV-8 Series Multiviewer supports HDR video inputs. Each multiviewer input has a
selectable video dynamic range converter (HDR to SDR) which can handle different opto-
electrical transfer functions (OETFs) and color space for HDR video inputs.
(See HDR Support, on page 75.)
Media Biometrics on Inputs
The MV-8 Series Multiviewer supports media biometrics on video inputs for media
assurance. Each multiviewer input has a media biometrics generator which generates
signatures for the input video and for the input audio. The media biometrics generators are
fully compatible with Grass Valley’s Media Assurance SigMA platform.
(See Media Biometrics Support, on page 79.)
Control and Monitoring
The control and monitoring interface is connected to one or more Ethernet network
interfaces on the MV-8xx product. It is used for:
• control and monitoring;
• software upgrades and licensing;
• all RollCall messaging; and
• pushing/pulling video wall designs (GV Orbit multiviewer projects).
Note: An MV-8x1/8x5 requires a corresponding ‘H.264 stream’ license.
For example, ‘MV-821-H264’for MV-821.
Note: Licensing for MV-821 products specifically involves factory-fitted
H.264 encoder modules.
