Joint Press Release: Global 8K Live Streaming Showcase 2020

8K Live Streaming over the Internet Showcased by a Group of Industry Leaders

In a significant milestone for the adoption of 8K, Intel, NHK Technologies, PSNC, Spin Digital, and Globo collaborate to deliver a live 8K program to multiple locations worldwide.

Portland, Tokyo, Poznan, Berlin, Rio de Janeiro, January 14, 2021 – A group of global leaders presented a demonstration of 8K live streaming over the Internet, providing a visible path towards 8K adoption for large scale live events.

The demonstration was presented on December 9th, 2020 at multiple locations worldwide, organized by Intel (US), NHK Technologies (Japan), Poznan Supercomputing and Networking Center – PSNC (Poland), Spin Digital (Germany), Globo (Brazil), and with the support of Sony (Japan/UK), Astrodesign (Japan), and Zixi (US).

“Transmitting broadcast-quality 8K content live over the Internet requires highly efficient video coding as well as reliable streaming technologies. This demo highlighted the possibilities of a state-of-the-art HEVC software encoder for reducing the bitrate needed for 8K live applications, as well as the possibility of delivering low-latency live 8K over the Internet. This is the result of our multi-year joint R&D efforts and perseverance to deliver more, better and faster pixels while collaborating with the industry leaders worldwide”, said Dr. Mauricio Alvarez-Mesa, CEO, Spin Digital and Ravindra Velhal, Global Content Strategist, Intel Corporation.

Key technologies used in the demonstration included:

  • Software HEVC real-time encoder that can compress 8K 60 Hz video with broadcast-grade quality at low bitrate and with low-latency
  • Low-latency live streaming over the Internet
  • 8K live production using 3 cameras
  • 8K HEVC software decoder and playback on 8K TVs with HDMI 2.1 interface

Seeing is Believing: End-to-end 8K Live Streaming

The immersive demonstration consisted of an end-to-end 8K live video showcase from live production to encoding, streaming and playback on 8K TVs.

An 8K live program was produced at the PSNC’s 8K studio in Poznan (Poland), the video signal was live encoded using Spin Digital’s HEVC encoder and streamed to multiple locations across the world, where it was received live and played on 8K screens. Viewing locations included NHK Technologies in Tokyo, Globo in Rio de Janeiro, Intel in Portland Oregon, and Spin Digital in Berlin.

Demonstration presented on December 9th 2020 at multiple locations worldwide, organized by Intel (US), NHK Technologies (Japan), Poznan Networking and Supercomputing Center - PSNC (Poland), Spin Digital (Germany), Globo (Brazil), and with the support of Sony (Japan/UK), Astrodesign (Japan), and Zixi (US).

8K Live Encoder by Spin Digital Optimized for Intel Xeon Scalable CPUs

The 8K content, with 7680×4320 pixels, 10-bit, at 60 frames/s, was encoded in real-time using the new HEVC software encoder. The encoder was able to provide broadcast-grade quality in a low-latency configuration at 120 Mbit/s, and the same level of quality was possible with a bit rate of 48 Mbit/s in a high-efficiency encoding configuration.

The new encoder is able to process 8Kp60 HEVC video in real-time using a CPU-only solution. It has been extensively optimized for Intel Xeon Scalable processors in order to achieve an unparalleled level of performance, with optimizations including advanced decision algorithms, SIMD processing using Intel’s AVX-512 instructions plus built-in AI acceleration from Intel DL Boost technology, and scalable multithreading for systems that can include hundreds of CPU cores.

8K Live Delivery over IP Networks Across the Globe

The 8K content was distributed to multiple viewing points across the globe using the open Internet. The streaming module of the encoder produced simultaneously an HTTP live stream (HLS) for final distribution, and a low-latency stream that was distributed using RTP and Zixi point-to-point protocols for reliable delivery over the Internet.

Playback on 8K TVs with HDMI 2.1

The 8K live stream was played back using a software HEVC decoder and 8K media player developed by Spin Digital and running on Intel Core i9 CPUs. The media player includes a flexible output module with support for different 8K interfaces including HDMI 2.0, HDMI 2.1, and 12G SDI.

The content was viewed at different locations on 8K screens from different manufacturers, among them Sony’s KD-75ZH8 8K HDR Full Array LED TV. The TV was connected to the player using an HDMI 2.1 interface via a professional SDI-to-HDMI converter developed by Astrodesign.

Low-latency 8K Live Internet Streaming

Combining the low-latency configuration of the encoder and the low-latency settings in the transport protocol it was possible to transmit 8K live video streams with a glass-to-glass latency between 1 and 2 seconds.

We measured the end-to-end latency from Poznan to the different playback locations using synchronized clocks. The table in this link presents the end-to-end latency measurements and the contribution of the different components in the pipeline.
