The VR-4HD is designed with single-person operation in mind, with easy switching and mixing of sound and video using advanced video and audio Digital Signal Processing (DSP) along with dedicated hardware controls faders, buttons and touchscreen interface. It beautifully integrates a digital audio mixer, video switcher, multi-viewer touchscreen and USB video/audio streaming interface into a stand-alone device. This portable live HD production solution is ideal for schools, churches, council meetings, corporate events, sports, training sessions or any other live event.
The VR-4HD features professional-quality broadcast controls and switches ensuring more accurate and faster operation than interfaces based on a computer-style mouse and keyboard. The ability to simultaneously switch video with the push of a button and adjust audio with the push of a fader is invaluable and puts all essential features at the operator’s fingertips. The built-in multiview screen is also a touchscreen interface for accessing set-up parameters, making it extremely easy to adjust picture-in-picture settings by dragging the inset window onto the screen.
The VR-4HD has three dedicated HDMI input connectors compatible with a variety of equipment and support 1080p/1080i/720p video resolution. The fourth input includes a scaler to support both video and computer resolutions and also supports analog RGB and component input so older devices can be used as sources without the need for external conversion equipment.
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.
The VR-4HD includes DSK (Downstream Keying), Picture-in-Picture (PinP), Split and Quad composting 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) for compositing two videos in one screen using Picture-in-Picture, or for using the split function—ideal for seminars and presentations.
