Final media player 2014 drivers#
Due to some limitations of GPU drivers this format did not not support any HDR format. This 2×2 HDMI 2.0 format was supported by early 8K TVs. The most common interface was four DisplayPort outputs that required, in turn, to be converted to four HDMI 2.0 connections before they could be connected to the 8K TV.

Until relatively recently, 8K playback using Spin Player or other software players required an AV interface with four cable connections. The entire chain is supported in HDR10 (PQ) and therefore conversions such as tone mapping are not needed.įigure 2: Flow chain of an 8K media player for HDR with PQ format 8K HDR with HDMI 2.1 Interface The figure below shows the player flow chain when using HDR10 (PQ).

Table 3: HDR support for PQ and HLG on Windows 10 PC systems using Spin Player The table below shows the capabilities of Spin Player when using GPU rendering on Windows 10. HLG content therefore has to be converted to SDR using tone (and gamut) mapping. Figure 1 illustrates the flow chain of a typical software media player with a GPU-based renderer.įigure 1: Flow chain of an 8K media player for HDR with GPU renderingĬurrently, when using Windows 10 PC systems only the HDR10 (PQ) format is supported for HDR playback. In addition, in a PC-based system, the video rendering engine has to perform composition with other graphical sources. The video renderer produces the final rendered frame that is sent over the digital AV interface to the display. The decoder decompresses the HEVC stream and passes the decoded video frames together with the metadata to the video renderer. The transfer function, colorimetry, and matrix coefficients can be transported using the Video Usability Information (VUI) messages of HEVC. The static HDR metadata can be transported in a Supplementary Enhancement Information (SEI) message together with the HEVC bitstream.
Matrix coefficients: BT.2020 PQ, BT.2020 HLG.When the media player receives an 8K HEVC bitstream, the following information is required for appropriate HDR playback: The following table shows the main properties of PQ, HLG, and HDR10. Other HDR formats support dynamic metadata such as Dolby Vision, HDR10+, and SL-HDR1.
If static metadata is added to PQ, the format is called HDR10. There are two main formats being used for HDR: PQ (Perceptual Quantizer) defined by the SMPTE ST2084 standard (and also in BT.2100), and HLG (Hybrid Log Gamma) defined by the ARIB STD-B67 standard (and also in BT.2100). Table 1: 8K format description HDR Formats and Standards for 8K Video The requirements of 8K professional and distribution 8K formats are summarized in Table 1. Therefore, an 8K media player has to support, at least, 8K resolution, 50 or 60 fps, 10-bit, some of the common HDR and WCG formats, and optionally HFR. In order to achieve this, the 8K format combines higher pixel counts (four times higher than 4K UHD), with High Dynamic Range (HDR), Wide Color Gamut (WGC), and potentially High Frame Rates (HFR). It is designed to provide a stronger sensation of reality and a greater immersive experience. The 8K video format is much more than higher resolution. We present the options available for 8K HDR playback and their capabilities and limitations, and we show how Spin Digital’s media player (Spin Player) can meet the requirements of 8K HDR applications using a software solution based on the latest generation of computing systems (CPUs and GPUs) and AV interfaces (HDMI 2.1).
