DGA: Distributed Graphics Architecture
AnyTiles scales infinitely without losing pixel quality by utilizing the latest distributed computing paradigm, to connect and coordinate multiple media players or controllers. Regardless of the size of the video wall, each controller only needs to handle the graphics on its corresponding screen to keep the entire wall pixel-perfect. Minimum efforts for maintenance are guaranteed.
The technology is named DGA, short for Distributed Graphics Architecture.
DGA’s innovative architecture is inspired by the Hadoop distributed computing technology promoted and used by Internet leaders including Google, Facebook, and IBM. Hadoop scales indefinitely as one adds more CPUs into the network. Likewise, DGA brings out the best of your video wall and delivers its richest performance.
The DGA technology enables AnyTiles to compare favorably against legacy video wall technologies.

AnyTiles vs. Video Scalers
The majority of hardware-based video wall solutions fall under this category. The limit in total resolution on a video wall built with this technology is usually 4K (3,840 x 2,160 pixels). The typical video scaler has 1 input and 4 outputs, enlarging a single 4K video to 4 times of FHD, or a single FHD feed to 4 of HD (720p). One can cascade these scalers to make very large video walls. However, the larger the video wall becomes, the fuzzier the resolution is.
As an example, on a 10-by-1 video stretch built with video scalers, the resolution on each screen is limited to 384 x 216. It’s comparable to the poor quality when watching YouTube at the lowest network speed.
AnyTiles is the sharpest in the industry compared to today’s mainstream video scalers, engineered for high-end video wall solutions.
AnyTiles vs. PC with Multi-head Graphics
High-end video walls that demand resolution beyond 4K are often achieved with PCs and multi-output graphics cards. Typical multi-head cards support 4 outputs per card, with maximum of 4 video cards per PC. This allows up to 16 screens to be connected to a PC. These multi-thousand-dollar PCs then need to be synchronized using multi-thousand-dollar software, such as the Dataton WATCHOUT. The cost and thermal dissipation challenges associated with these solutions make them impractical for most long-term video wall installations. The service cost for such video walls is prohibitive.
AnyTiles offers a much simpler architecture by utilizing a low-power CPU at each screen. Similar to the Hadoop cloud computing architecture, which harnesses the fullest computing power from a large number of simple, reliable, inexpensive nodes, AnyTiles clusters can scale to video walls of any size while maintaining the perfect display resolution.
AnyTiles is designed to save multi-thousand dollars associated with set up, maintenance and service costs from solutions currently adopting PC with multi-head graphics.
AnyTiles vs. SOC Video Players
Many of today’s low-end and low-cost video walls are built using screens with built-in SOC technology. These systems may claim that they can scale to a large number of screens. However, in actual field deployment, screen synchronization (the ability to avoid tearing between adjacent screens) is often poor especially when the size of the video wall increases. Most of these systems are also limited to video playback only and use proprietary content format incompatible with mainstream authoring tools.
AnyTiles remains unaffected regardless of the size or the content needing to be synchronized.
