Recommended Systems for 8K Playback

By Mauricio Alvarez-Mesa, PhD Spin Player is based on a highly optimized HEVC decoder and video rendering engine. This software solution allows to play 8K video using compact and cost-effective PC systems.

In this tech blog we provide a set of recommendations of PC configurations for 8K video playback, and we also describe 8K display set-ups using commercially available 8K TVs and monitors.

Spin Player Performance

The final performance of the media player depends mainly on the content properties, input bitrate, and the platform performance:

  • Content properties:  The player’s performance is affected by content properties such as resolution, chroma format (4:2:0, 4:2:2, 4:4:4), bitrate,  and spatial and temporal activity in the input video.
  • Bitrate: HEVC decoding performance depends directly on the input bitrate, the higher the birate the higher the performance required to achieve a target  application (e.g. 8Kp60). The bitrate, in turn,  depends on the encoding options that were used during the encoding of the input video, including among others: bitrate settings, rate control method, GOP size, intra-frame period,  and block size.
  • Platform performance: The decoding performance directly depends on the CPU performance:  clock frequency and number of CPU cores. Video rendering performance, in turn, depends on GPU performance: frequency, number of cores, memory bandwidth.

Parallel Scalability

The HEVC decoder integrated in Spin Player has been extensively optimized for performance with advanced multithreading in order to make an efficient use of modern multicore CPU architectures. Different parallelization methods are supported including : Wavefront Parallel Processing (WPP), slices, tiles, and frame-level parallelism. The best method is automatically selected by the player.  Common formats used in the industry and supported by Spin Player include:

  • WPP: commonly used by software encoders
  • 4 slices: as defined by the ARIB ATD-B32 standard
  • 2×2 tiles: used by some 8K hardware encoders

The performance of the Media player scales very well with the number of CPU cores. By using CPUs with higher core counts it is possible to increase the performance for applications that require higher bitrates, higher quality chroma formats (4:2:2 or 4:4:4), higher frame rates, and even higher resolutions.

PC Configuration for 8Kp60 Playback

We have conducted a detailed benchmarking analysis using hard-to-decode content in 8K resolution in order to identify the required properties of the system for 8Kp60 payback applications.

The table below describes the properties of the recommended platform for 8K contribution and distribution use cases. The recommended bitrate for each application is a range of bitrates being used in the industry for 8K applications. The maximum bitrate is the maximum rate that can be achieved by using the described PC platform.
