Additional Features:

  • Inputs:
    • The V-1SDI has (2) dedicated 3G SDI inputs, a third channel input that supports 3G SDI or HDMI and a fourth channel HDMI input that also includes scaling. Inputs 1 to 3 of the V-1SDI support 1080p/1080i/720p video resolutions with Input 4's scaler supporting a wider range of video and VESA resolutions. This makes the V-1SDI ideal in a variety of configurations for both an all camera applications and applications that mix cameras, video sources and computer data sources. Both progressive and interlace signals can be input allowing for both 1080i and 1080p signals to be used at the same time. Video signals input from a PC are accurately displayed thanks to progressive signal processing. HDCP is supported* for input of copy protected content from devices such as Blu-ray disc players.

NOTE: *Video is only output from HDMI when HDCP isenabled. SDI outputs are disabled when HDCP is enabled.

  • Outputs:
    • The V-1SDI has (2) 3G SDI Outputs and one HDMI output. SDI PVW and MULTI-VIEW outputs are assignable from Program, Multi-view Preview or Full Frame Preview for flexibility in different applications where output display devices support either SDI or HDMI inputs.
  • Quad Input Multi-viewer:
    • The four-way multi-view preview screen shows all 4 input sources on a single display for confident monitoring. A red border shows the video currently being output and a green one indicates the video to be output next. The V-1SDI multi-view includes audio metering for all input sources and the main outputs. The multi-view also supports the on-screen display for the menu operations and for completely self-contained operation.
  • Composition Effects:
    • The V-1SDI includes DSK (downstream keying), Picture-in-Picture (PinP), Split and Quad compositing effects ideal for creating news style broadcasts and corporate presentation content. The DSK function is great for overlaying titles, song lyrics or logos onto incoming video sources that can be switched in the background while text or images remain displayed.  The DSK supports both Luminance Keying (Black / White) and Chroma Keying (Blue / Green). When using PinP, sources can be layered as an inset widow for applications such as placing a presentation from a PC source as a PinP over a camera source that is focused on a meeting presenter. Split mode is perfect for compositing two camera sources with a speaker or presenter on each camera and placing them side by side so both can be seen at the same time.
  • Audio Mixing:
    • Included is a 14 channel digital audio mixer. The V-1SDI can mix 5 stereo audio inputs from the SDI or HDMI ports, the stereo line level input and a mic level input. Every audio input is equipped with a delay function* to synchronize the video and the audio. Audio follow function enables the audio to transition along with the video. Reverb function and mastering function used for adjusting sound quality and volume are also supported. The final audio mix is both embedded in the SDI and HDMI output along with the video signal and is also output to the stereo audio output jacks for sending the audio mix to a PA system or recording it on an external device. Audio Metering is also supported on the connected multi-view display.

NOTE: *The maximum delay time is 500ms.

  • Remote Control:
    • Remote control is possible with the V-1SDI RCS dedicated computer software for Mac and PC connected via a USB cable. The application offers a detailed view of the connected V-1SDI and can be used to switch video, mix audio or change settings.  For integration with A/V control systems, the V-1SDI is equipped with a serial connection for control by industry standard RS-232 serial controls.
