USB 3.2 specification arrives this year with confusing new naming structure

01 Mar

The USB 3.2 specification announced by the USB Implementers Forum (USB-IF) in 2017 will be arriving soon, and it’ll bring a relatively convoluted new naming structure with it. As was the case when the USB 3.1 specification launched, the new USB 3.2 spec will absorb the previous generations before it, designating them as Gen 1 and Gen 2.

The new USB 3.2 specification, which brings speeds up to 20Gbps, will be known as USB 3.2 Gen 2×2. Joining this will be USB 3.2 Gen 1, which originally launched as USB 3.0 and was later renamed USB 3.1 Gen 1; this specification supports transfer speeds up to 5Gbps.

Between the two will be USB 3.2 Gen 2, which originally launched as USB 3.1 and was late renamed USB 3.1 Gen 2; this specification supports transfer speeds up to 10Gbps. In order to hit the 20Gbps speed, USB 3.2 Gen 2×2 will utilize two of these 10Gbps high-speed channels.

To help consumers understand which version they’re getting, the USB-IF suggests manufacturers use the following terms:

  • USB 3.2 Gen 1: ‘SuperSpeed USB’
  • USB 3.2 Gen 2: ‘SuperSpeed USB 10Gbps’
  • USB 3.2 Gen 2×2: ‘SuperSpeed USB 20Gbps’

According to The Verge, the new USB 3.2 specification will hit the market sometime this year.

The new HDMI 2.1 specification (and cable) adds support for 10K, 8K HDR, and 4K at 120fps

02 Dec

Originally announced back in January and slated for a mid-year release, the HDMI 2.1 specification is just now making its debut on the world stage. Announced by the HDMI forum yesterday, the new specification offers users the ability to deal with 10K video resolution, as well as other data-intensive formats such as Dynamic HDR, uncompressed 8K HDR video, and 4K at 120fps.

A new Ultra High Speed HDMI Cable standard has also been announced that carries up to 48Gbps, and which is said to have ‘exceptionally low electro-magnetic interference’ to avoid conflict with other devices in the vicinity.

HDMI 2.1 is backwards compatible with earlier versions of the standard, as is the new high speed cable. For more information, visit the HDMI forum website.

HDMI FORUM RELEASES VERSION 2.1 OF THE HDMI SPECIFICATION

A Huge Leap Forward Supports Resolutions Up to 10K and Dynamic HDR and Introduces New Ultra High Speed HDMI Cable

SAN JOSE, California – November 28, 2017 – HDMI Forum, Inc. today announced the release of Version 2.1 of the HDMI® Specification which is now available to all HDMI 2.0 adopters. This latest HDMI Specification supports a range of higher video resolutions and refresh rates including 8K60 and 4K120, and resolutions up to 10K. Dynamic HDR formats are also supported, and bandwidth capability is increased up to 48Gbps.

Supporting the 48Gbps bandwidth is the new Ultra High Speed HDMI Cable. The cable ensures high-bandwidth dependent features are delivered including uncompressed 8K video with HDR. It features exceptionally low EMI (electro-magnetic interference) which reduces interference with nearby wireless devices. The cable is backwards compatible and can be used with the existing installed base of HDMI devices.

Version 2.1 of the HDMI Specification is backward compatible with earlier versions of the specification, and was developed by the HDMI Forum’s Technical Working Group whose members represent some of the world’s leading manufacturers of consumer electronics, personal computers, mobile devices, cables and components.

“The HDMI Forum’s mission is to develop specifications meeting market needs, growing demands for higher performance, and to enable future product opportunities,” said Robert Blanchard of Sony Electronics, president of the HDMI Forum.

HDMI Specification 2.1 Features Include:

  • Higher video resolutions support a range of high resolutions and faster refresh rates including 8K60Hz and 4K120Hz for immersive viewing and smooth fast-action detail. Resolutions up to 10K are also supported for commercial AV, and industrial and specialty usages.
  • Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast and wider color gamuts—on a scene-by-scene or even a frame-by-frame basis.
  • The Ultra High Speed HDMI Cable supports the 48G bandwidth for uncompressed HDMI 2.1 feature support. The cable also features very low EMI emission and is backwards compatible with earlier versions of the HDMI Specification and can be used with existing HDMI devices.
  • eARC simplifies connectivity, provides greater ease of use, and supports the most advanced audio formats and highest audio quality. It ensures full compatibility between audio devices and upcoming HDMI 2.1 products.
  • Enhanced refresh rate features ensure an added level of smooth and seamless motion and transitions for gaming, movies and video. They include:
    1. Variable Refresh Rate (VRR) reduces or eliminates lag, stutter and frame tearing for more fluid and better detailed gameplay.
    2. Quick Media Switching (QMS) for movies and video eliminates the delay that can result in blank screens before content is displayed.
    3. Quick Frame Transport (QFT) reduces latency for smoother no-lag gaming, and real-time interactive virtual reality.
  • Auto Low Latency Mode (ALLM) allows the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity.

The HDMI 2.1 Compliance Test Specification (CTS) will be published in stages during Q1-Q3 2018, and HDMI adopters will be notified when it is available.

SLR Magic’s Anamorphot-Cine 1.33x lenses now shipping with revised specification

25 Feb

Lens manufacturer SLR Magic has announced ‘significant’ changes to the optical and mechanical specification of its Anamorphot-Cine 1.33x anamorphic lenses, which it says are now available. The lens set was first shown at IBC (the International Broadcasting Convention) at the end of last year, but the company says the latest versions have crucial differences – although they don’t say exactly what those differences are. SLR Magic says that the lenses can now be calibrated by lens technicians outside of Hong Kong. 

The PL-mount anamorphics can be adapted to fit Canon EF, Sony E, Nikon F and Micro Four Thirds cameras, and will come in 35mm T2.4, 50mm T2.8 and 70mm T4 focal lengths. The 35mm lens covers Super 35mm, while the 50mm and 70mm are good for full frame cameras. The lenses are designed to stretch the 16:9 frame by 1.33x to create a 2.35:1 widescreen aspect ratio so that filmmakers don’t need to crop off the top and bottom of their 4:3 footage. 

Currently prices are only available in Hong Kong dollars, so the US prices shown are straight conversions using today’s exchange rate. 

  • SLR Magic ANAMORPHOT-CINE 35mm T2.4  HK$ 46,680/US$ 6008
  • SLR Magic ANAMORPHOT-CINE 50mm T2.8  HK$ 50,550/US$ 6506
  • SLR Magic ANAMORPHOT-CINE 70mm T4     HK$ 50,550/US$ 6506

A demonstration of the lenses’ capabilities with the Panasonic GH4 and Sony a7S can be seen in the short film ‘Feel’ above. For more information about the company visit the SLR Magic website. 

Press release:

Hong Kong, China (Feb 22th, 2016) – SLR Magic is proud to announce the SLR Magic ANAMORPHOT-CINE 1.33x PL lens set for filmmakers which could be adapted to EF/F/mFT/E-mount via adapter. The production version has changed significantly in both optical and mechanical specification compared to the lenses shown at IBC 2015. For absolute precision, the lenses could now be calibrated by a lens technician from abroad rather than having both the camera and lenses to be calibrated in Hong Kong.

Please enjoy our short film, “FEEL”, taken by our volunteers with the new 1.33x SLR Magic Anamorphot-CINE lenses power driven by the Movcam Wireless Focus System on the Panasonic GH4 and Sony A7s recorded with the Atomos Ninja Assasin 4K recorder/monitor.
