The Emporium Shopping Centre
The Emporium shopping centre in Bangkok holds place to two large, rectangular video walls, opposite each other, towering over the shopping floor. Both walls featuring advertisements and displays next to the centres escalators so that they simply cannot be missed by the visitors.
Each wall is connected via HDMI and consists of 4 G4K PROs, daisy chained together to fuse 15 screens. The G4K Pro standalone serial video wall controllers accept a single 4K input source and divides it across up to four displays, each with a resolution up to 1920×1200 @ 60Hz. Each output supports rotation of any degrees. Each output is also able to crop the original input content arbitrarily. The resolution and frame rate of outputs can be upscaled and downscaled freely for all sorts of applications. In addition, whenever the input signal includes embedded audio, the G4K Pro is able to support audio output. This makes the G4K Pro the ideal solution for eye catching creative video walls, where audio is also required
The walls are used all year round but considering its now very much Christmas time, The Emporium has the freedom of creativity with the G4K Pro and are able to expand their festive content in a way that suits a video wall of this shape. Via the specialist G4K Pro software, they have been able to lock and unlock the aspect ratio in order not to lose any content. They can simply unlock the aspect ratio, removing the need to expand their video and stretch it whilst losing vital aspects of the content itself.
The Emporium also required a purely hardware-based controller due to the fact that the video wall needs to run continuously throughout the day without failure. Because the G4K Pro is purely hardware based, it means that there is no operating system involved that has the possibility of crashing or buffering. There is also almost zero load time, so the shopping centre manager is able to open up in the morning and switch on all electricity without having to setup the video wall again. Once the layout is configured via IP connection, the windows-based PC can be unplugged, and the video content will continue to run. With the added possibility of saving up to 4 layouts to the G4K Pro controller, store managers or staff are able to remotely change the video wall content using an iPhone app – the iGPro (follow this link for more information – Seada iGPro).
