What features are most important to chose Video Wall Controller solution?
1. Why do we need to use video wall controller?
In the world of digital signage, video wall controller is like a traffic cop: it ensures that every signal content displays exactly where it should be, on the right screen, at the right time, in the right resolution. Video wall processor is a device that enables a single image to appear and move seamlessly across multiple screens in a video wall. Without it, video wall would be just a bunch of digital screens with separated contents on each single screen.
The processor forms a complete and large image, and displays part of it on the various screens. While smaller, simpler video walls may only require a multi-head graphic card, as video walls continue to grow in size and functionality, most require processors.
Video wall controllers are now available in hardware-based and software-based versions. Hardware processors are built on a series of physical video processing chipsets and have been in use for years. Today a new form of IP-based video wall controllers run on Encoder, Decoder, which connects the singal sources with display devices by network . Each has its own advantages and disadvantages, depending on the project, so you may want to do some research before making decision.
