Roland's V-1HD+ Compact 4 x HDMI Video Switcher is a portable solution for HD video production that accommodates up to four HDMI inputs, as well as PC resolutions over one of the inputs. Each input has a frame buffer/TBC and support frame rate conversion, so you don't need to genlock your input sources together. You can control the switcher manually by using the built-in controls or remotely via RS-232, and it has a tally output for working with live cameras. Select your working resolution and switch between four input sources. Built into the switcher is a 14-channel audio mixer that can de-embed and embed audio signals from HDMI.

The integrated T-fader allows you to manually control the speed of transitions, or you can use the take button to actuate your selected transition. The unit features two HDMI outputs, both of which are selectable between program and multiview (with up to 10-views on each output), and output #2 also supports an on-screen menu display. The V-1HD+ also features a four-layer effects engine that supports keying effects, PiP, and downstream keys. It has internal memory for four still images, and you can access external drives via the USB port as an additional image source.
