The HDMI Forum has just announced they’ve been working on HDMI specification Version 2.1 adding new video resolutions and refresh rates including 8K60 and 4K120, as well as dynamic HDR, and increased bandwidth up to 48 Gbps for uncompressed 8K videos with HDR. The new specification also includes support for eARC (enhanced audio return channel) with support for advanced audio formats such as object-based audio, and advanced audio signal control capabilities including device auto-detect. Game Mode VRR is another new feature from HDMI 2.1 with variable refresh rate to enable a 3D GPU to display the image at the moment it is rendered in order to reduce lag and frame tearing. Beside 4K120 and 8K60, the new specification also handles 4K, 5K, 8K, and even 10K resolutions at various frame rates between 50Hz to 120 Hz, up to 10K @ 120 Hz. Higher resolutions and frame rates (>=4K @ 120Hz; […]
Nvidia Unveils Xavier Automotive & AI Octa-core SoC with 512-Core Volta GPU, 8K Video Decode & Encode
Nvidia has introduced the successor to their Parker SoC mostly targeting self-driving cars and artificial intelligence applications, with Xavier SoC featuring 8 custom ARMv8 cores, a 512-core Volta GPU, a VPU (Video Processing Unit) supporting 8K video decode and encode and HDR (High Dynamic Range), as well as a computer vision accelerator (CVA). The processor will deliver 20 TOPS (trillion operations per second) of performance, while consuming only 20 watts of power, and since it’s designed specifically for autonomous cars, it will comply with automotive safety standards such as ISO 26262 functional safety specification. Anandtech published a comparison table with Tegra X1 (Erista), Parker, and Xavier using currently available information. Xavier Parker Erista (Tegra X1) CPU 8x NVIDIA Custom ARM 2x NVIDIA Denver + 4x ARM Cortex-A57 4x ARM Cortex-A57 + 4x ARM Cortex-A53 GPU Volta, 512 CUDA Cores Pascal, 256 CUDA Cores Maxwell, 256 CUDA Cores Memory ?

DisplayPort 1.4 To Support 8K Displays over USB-C, 4K@120 Hz, 32 Audio Channels
Just as 4K UHD televisions are getting more affordable with prices ever closer to their Full HD equivalent, the Video Electronics Standards Association (VESA) has published DisplayPort 1.4 specifications with support for 8K QUHD (7680 x 4320) resolution, High Dynamic Range (HDR), video compression and more. Some of the key enhancements or new features of the new specifications include: Up to 8Kp60Hz HDR deep color and 4Kp120Hz HDR deep color Display Stream Compression (DSC) – DSC 1.2 natively supports YCbCr 4:2:0 and 4:2:2 coding, and offers nearly lossless 3:1 compression ratio Forward Error Correction – FEC, which overlays the DSC 1.2 transport, addresses the transport error resiliency needed for compressed video transport to external displays. HDR meta transport – HDR meta transport uses the “secondary data packet” transport inherent in the DisplayPort standard to provide support for the current CTA 861.3 standard, which is useful for DP to HDMI 2.0a protocol […]
superMHL Standard Support 8K Video Output, 48-bit Color Depth, Dolby Atmos, and More
As we all just so happen to play with our 4K television… NOT, the MHL Consortium is already preparing for the future with a new superMHL specifications supporting 8K video up to 120 fps, the ability to charge more powerful devices, new audio format support and more. Key features of superMHL specifications: Delivery of up to 8K 120fps video (4320p @ 120 Hz) Deep Color support up to 48-bit color depths Wider color gamut to view content the way filmmakers intended High-Dynamic Range (HDR) support to strike the perfect balance of bright spectral highlights along with shadow details Immersive surround sound with support for object audio such as Dolby Atmos, DTS-UHD, 3D audio, and an audio-only mode Advanced connectivity configurations to link multiple MHL devices together (TV, AVR, Blu-ray player) and control them via one remote Power charging up to 40W Content on multiple displays when connecting a single device […]
