Learning About HDMI Video Multiviewers
Video multiviewers allow you to monitor multiple video signals on a single screen. Multiviewers are ideal for professional settings when managing several videos or feeds at one time.
The Best Applications for Multiviewers
Multiviewers are used frequently in broadcast and production control rooms because they display multiple camera angles, and allow you to quickly select the main live feed. They're also great on film sets as they allow directors to see multiple camera angles recording simultaneously from a single scene. Multiviewers are also helpful for security systems, as you can monitor different surveillance feeds simultaneously.
HDMI Multiviewer features to consider include the number and type of inputs, and whether you need to work with digital or analog systems.
Number of Inputs
One of the first features you need to consider when purchasing multiviewers is the number of inputs. Depending on how many signals you need to monitor on a single panel, you can find multiviewers with over 30 inputs. A larger screen is optimal when using a large amount of inputs.
Type of Inputs
Another important consideration is the type of input that your multiviewer supports. 4K-compatible multiviewers help you connect the highest-quality video feeds to your display. If you're using a range of different feeds with various qualities, it's essential to find one that can support all of your inputs. Mixed high-resolution units can support both analog and digital feeds, along with HD, SD, and other video types. Many multiviewers have numerous output options, including USB, DV-I, HDMI, and more.
Digital, Analog, and More
HDMI multiplexers allow you to combine analog, digital, and a range of other video input systems. Once these signals combine, a multiplexer sends them at a uniform speed to your display panel. If you're using a range of different video input signal types, then a multiplexer is an essential addition to your multiviewer.
Other Types of Multiviewers
To display large, electronic signage in stadiums or other public areas that have commercial monitors and displays, use display controllers to show large images on massive screens while maintaining high resolution and stable frame rates.
If you want to show a single, dynamic image across screens that are set up side by side, use video wall processors. These ensure that the image travels across multiple monitors seamlessly.
A production or broadcast control room might opt for a video wall with multiple screens instead of one large panel. In this case, video wall controllers can help you manage the screen display. You can set the video wall to display one continuous image, or set different screens to display multiple camera angles and feeds simultaneously.
Regardless of the project, you can find a varied selection of video multiviewers and other video processing and distribution equipment at B&H Photo and Video.
