Spin Digital Planned VVC 8K Video Demo at IBC

Spin Digital was planning to use IBC to show off its latest encoding and decoding solutions. With the cancellation of the event, the company is now focused on doing a video of their planned demonstrations. This will include live 8K encoding/decoding using HEVC and off-line VVC encoding and playback of 8K video content to 8K TVs. These demos showcase recent advancements to their live encoder, Spin Enc Live, and the new 3.0 version of the Spin 8K Player. Bit rates for these demonstrations are shown below. Note that Spin Digital is demonstrating the scalable nature of VVC allowing both 4K and 8K layers to be delivered in a single stream at very reasonable data rates.

  • 8K HEVC live encoding 4:2:0 10-bit @ 50 or 60 fps: 48 Mbit/s
  • 8K VVC playback (single layer) 4:2:0 10-bit @ 50 or 60 fps: 25 Mbit/s
  • VVC playback (4K and 8K layers) 4:2:0 10-bit @ 50 or 60 fps: 30 Mbit/s

New version of the 8K HEVC live encoder. Note that this is both an encoder as well as a packager to deliver streaming outputs.

  • Optimized for the latest generation CPUs. It can perform 8K 60 fps, 10-bit HDR real-time encoding in a standard dual-socket Intel Xeon Platinum 8380 Processor (2×38 cores) server platform.
    • The encoder accepts uncompressed 4:2:2 from SDI inputs and can encode in 4:2:0 and 4:2:2
    • The newly optimized encoder runs on the new Xeon Ice Lake Platform which obtains higher performance for media operations. This allows only 2×38 cores for live 8K encoding comparted to the 4×28 cores of the Xeon Cascade Lake platform used for the Olympics demo.
  • Added a new real-time 8K perceptual-optimized encoding mode that achieves higher subjective quality at lower bitrates
    • Spin Digital developed a mathematical model of human visual perception for 8K HDR video and used this model to guide the internal encoder decisions. One main feature is that the model and the encoder adaptations can run in real-time for 8Kp60 live encoding.
    • With perceptual-optimized encoding (POE) Spin Digital says it can guarantee broadcast-grade quality at 48 Mbit/s, which is their recommended bitrate for 8Kp60. The POE mode allows them to maintain the required quality even when the content is very demanding. The company is performing further validations with subjective and objective tests.
  • Other new features: flexible SDI input capture, real-time Adaptive-Bitrate (ABR) encoding and streaming, support for the ARIB format for 8K broadcasting in Japan, and low-delay reliable streaming over the internet with SRT, RIST, and Zixi protocols.
    • Flexible SDI makes it is possible to capture, for instance, a panoramic resolution of 15360×2160 (4 x 4K) pixels over a quad link 12G-SDI card.

New version of Spin Digital Media Player (Spin Player v3.0-preview) – redesigned for 8K and beyond

  • Live applications that require very low-latency
    • Support for uncompressed YUV with additional metadata in JSON format playback up to 8K, 4:2:2, 12-bit, 120 fps
  • Higher performance and smaller form factors for HEVC playback using latest generation CPUs
    • Intel Core i9-9940X (14 cores) & Nvidia RTX 3060 GP for live HEVC 8K/60 playback
    • AMD Ryzen Threadripper 3960X (24 cores or Intel Xeon Gold 6330 (28 cores & Nvidia RTX 3060 for VVC 8K/60 playback
  • Spin Player VVC is a special variant of the player with support for the VVC codec including Main 10 and Main 10 scalable profiles.

We will advise when the video of their demonstrations is posted, or check for updates.
