  • Showcase LED boarding

    First of all many thanks for your support, especially Yuriy. Afterwarp is an awesome piece of software and I would like to take the opportunity to show you a special case you would never expect that there is a 3D rendering engine behind. Well we just using the 2D parts but anyway but it's the technology.

    Currently we are using the Asphyre engine to draw static and video content on an extended screen. But we reached now the performance limit of this engine and where looking for a better solution.

    What are we doing exactly with our LEDVIZ software? You can call it a video player but it's more than this. The content is aligned to fit the output of a LED boarding like you know it from many sport events. One sample with the advertising of KIESER TRAINING is shown below. The picture was captured from a 1st division soccer game in Germany with our running LEDVIZ software. A full video with animated content is available here ->

    Now you may ask why we are using a 3D rendering engine? Our software is able to provide live content. That means everything is rendered synchronized in realtime. All other software like Pandoras Box or Watchout running mostly with pre rendered content, which mean you are not able to change the content while the game is running. LEDVIZ handle everything by drag &drop and play it out directly.

    The picture above shows a special feature. The content is scaled live while playing! In the back you see 2 rows of LED boardings. The KIESER TRAINING was delivered in 2 video files, first and second row. The distance between the 2 rows are 5 meters. Because of this distance the second row need to be aligned to the main TV camera position, so that it looks like it's one big picture. The main TV camera stands on a triopod and you never know the exact position. You get it up to 3 or 4 hourse before the game. So you are lost with pre rendered content :-) and here come the advantage of the rendering engine.

    Currently we have enough power to handle a game like the sample above with 450 meter of LED boarding with 2 syncronized computers. Our issue is the performance limit. We would like to add a multifeed function. That means different TV camera's showing different content on the LED boarding at the same time. Useful for TV broadcasting to different countries. Our technology provider has the ability to provide up to 4 TV feeds. The problem is the content need to be rendered on the same extended screen We are currently drawing the content for one TV feed and getting a average of 50 FPS. If we want to use this multifeed feature we have to double or quadruple the content on the extended screens. This require the support for 2x 4k displays. If we would now just extend the drawing with the Asphyre engine our framerate drop to 10 FPS. Which is not enough for broadcasting. Required are 50 FPS or at least a minimum 25 - 30 FPS for broadcasting.

    Our first test with the Afterwarp engine showing a boost of +150% - 300% of FPS. It's not only the engine itself, it's also the way of implementation which give us the chance to avoid unnecessary conversion to other formats :-) ... we are very excited ...

    During previous Winter Olympics in Pyeongchang (2018), I noticed that the floor and other parts that were looking much different on certain TV channels than on others, which made me to believe they were digitally processed in real-time, now I know a particular technology that makes this possible. Thank you very much for the post, this is just amazing!
