Primary Output Mode
The MVPHD-24 is not capable of producing perfect images on all outputs simultaneously. Therefore the
primary output mode is used to select the desired output that is most important. The other outputs may
continue to work but the quality may be degraded.
Output Frame Rate and Formats
All output signals from the MVPHD-24 operate at the chosen frame rate (23.976, 24.000, 25.000, 29.970, or
30.000 Fps). The available output formats are determined by the Output Frame Rate and the Primary Output
Mode.
Composite / YC / Component Outputs
The analog video outputs use 3 multi-purpose BNC connectors for either composite/Y/C signals or
component signals as chosen by the Primary Output Mode. The Composite/Y/C signals may be NTSC or
PAL color subcarrier. Component signals are YPbPr (Betacam or SMPTE-EBU levels), and RGB (sync on
green) color formats.
SDI Outputs
The SDI outputs supports SD (270Mb/s) and HD (1.485Gb/s – 2.97Gb/s) formats up to 1080p-60.
HDMI Output
The HDMI output supports video formats from SD to HD resolutions and graphic formats up to
1920x1080p.
VGA Outputs
The VGA outputs produce standard VGA resolutions up to 1920x1080p.
CBVS/Ref Outputs
The Ref outputs can be individually configured to output various sync reference signals, or composite video.
Outputs include composite video, composite sync, black burst, tri-level, TTL composite sync, TTL Vertical
Drive, and TTL Frame Drive. For composite outputs, a low quality secondary scaler is used to down convert
any output resolutions that are higher than standard definition. This composite output is intended to be a
reference only, when producing other non-composite output signals. For optimum composite quality,
“composite” should be chosen for the Primary Output Mode.
Genlock
The Genlock input provides a high impedance “loop through” connection for an external sync reference. The
reference may be composite sync, black-burst, tri-level sync, TTL vertical drive, or a TTL frame square
wave. The reference signal may be daisy chained through several MVPHD-24s, or other equipment requiring
external sync. If the unit is the last piece of equipment in the chain, then the second connection will require a
termination. If no signal is applied to either connector then an internal sync generator is used for the
reference.
