Media Server Keeps Up with 8K, Multiple 4K Streams

Media Server Keeps Up with 8K, Multiple 4K Streams

As high-end customers demand more pixels for their uber-large screen displays, there’s an 8K media server available that can do the job

  • Be they the world’s premier auto shows, giant theme parks, or major business events, today’s high-end users of uber-large video displays are demanding more pixels than ever before. These users want to play out stunning visual content at resolutions as high as 8K (7680×4320 pixels) if possible. If not, then a mix of 4K (3840×2160 pixels) video streams will do.

What to Look for in a Modern Media Server
With the growth of 4K and the push towards 8K, video presentation purchasers would be wise to take a ‘future-proof’ approach to media servers

1) Scope out your long-term needs first
Before selecting a media server or family of media servers, determine your own playout needs. Will you need multiple 4K channels? Is 8K on the horizon? Then buy media services that will have enough ‘headroom’ for their expected operational lifespans with your company.
2) It’s all about hardware and software
A media server’s hardware is only as good as the software that operates it. Quiz each vendor as to the capabilities of each; how their hardware and software interact on their media server platforms, and what their upgrade/support plans are.
3) Buy enough computing power
A modern media server needs lots of processing power to serve 8K and 8K video streams reliably; with no hesitations or dropouts. Get as much CPU capacity as you can afford, and make sure that your system supports the highest-possible data rates. The catch: “Whether in 8K or 4K, these video streams need to be uncompressed to fill giant screens with as much detail as they can,” said Danny Whetstone; founder and president of the production house DWP Live in Nashville, TN. “Compressed video may look good on a 70" display, but it won’t cut it on a massive video wall,” he said.

Serving such massive pixel playouts requires one or more media servers with the sheer processing power, gigantic hard drive capacity, and rock-solid reliability to keep these playouts running without interruption 24/7. One such super-powered media server exists; namely AV Stumpfl’s powerful 8K Wings Engine RAW media server.

A case in point: MATRIXMANAGEMENT GmbH integrated seventeen AV Stumpfl Wings Engine RAW and three Wings Engine Stage media servers that powered approximately 700 square meters of high-resolution 3.5 mm pitch LED displays -- spread across four screens – in Audi’s main presentation area at the 2015 IAA International Motor Show in Frankfurt, Germany. Using the combined output from these 20 AV Stumpfl media servers, the LED screens displayed a total of 36,000 horizontal pixels in uncompressed format. That is something that couldn’t be done using conventional compressed video. (For the record, the largest screen used a single-stream of uncompressed video at 12240x1907 pixels and the smallest screen produced an unprecedented 7208x2312 pixels.)

Besides offering 8K/4K video playout, the 8K Wings Engine RAW media server can display video content using a full 12-bit colour depth; delivering more color information than the current media server standard. “As well, the RAW media server’s rendering engine can support high frame rate footage of up to 120fps, and can create seamless 8K soft edge blending panoramas,” said Stucken. “You can even play out native image sequences like TGA or TIFF without converting them into an intermediate codec format: The 8K Wings Engine RAW media server can handle it.”

Add the ruggedness to play this demanding level of uncompressed content on a continuous basis, and AV Stumpfl’s 8K Wings Engine RAW media server is a highly capable option for 8K/4K video playout. To prove this fact, DWP Live has teamed with AV Stumpfl USA to provide side-by-side comparisons of uncompressed vs. compressed playout at InfoComm 2017. It is scheduled to be held June 14-16, 2017 at the Orange County Convention Center in Orlando, FL.
