High Standards for HDMI

December 14, 2017 at 8:00 AM

 

Becoming a certified HDMI product is no simple task. HDMI Licensing LLC. has high standards for products that claim compliance and meeting their requirements is no easy feat.

 

To be HDMI compliant, a representative sample of each licensed HDMI product or component must pass rigorous testing prior to mass production or distribution. Here’s an inside look at everything that goes in to meeting the high standards for HDMI.

 

First, the manufacturer must become an HDMI adopter. They then self-test according to the most current HDMI Compliance Test Specification. This year, HDMI 2.1 is being released and is the most current specification. The test specification has a list of testing procedures and minimum requirements for how to test each product. This testing is limited and only evaluates the product’s HDMI compliance, it is not designed to test the overall product performance.

 

Next, the manufacturer must submit the first product of each product type (i.e. cable, sink, repeater or source) to an authorized testing center (ATC) for further testing. To submit a product for testing, the manufacturer must fill out an application, submit the product, provide all operating instructions or manuals, complete a capabilities declaration form and submit any ancillary material or equipment. The product is then evaluated for a pass or fail result. If a passing result is given, it is not required to test any other products of that type. If the product fails the compliance testing, the manufacturer is given a list of areas that did not pass, so they can make changes as needed.

 

 

With this year’s release of HDMI 2.1, comes a list of new specifications that must be met by HDMI certified products. These new requirements are available to all HDMI 2.0 adopters. HDMI 2.1 features include:

 

  • ·       Higher video resolutions and faster refresh rates
  • ·       Dynamic HDR for improved depth, brightness, contrast and wider color gamuts  
  • ·       48G cables for enabling up to 48Gbps speeds for uncompressed HDMI 2.1 feature support including 8K video with HDR
  • ·       eARC to support the most advanced audio formats and enable advanced audio signal control capabilities
  • ·       Game Mode VRR with variable refresh rate
  •  

As with all HDMI specifications, compliance testing must be performed for products to meet the HDMI 2.1 standards. All HDMI 2.0 adopters will have access to the HDMI 2.1 Compliance Testing Specification. The HDMI 2.1 specification supersedes HDMI 2.0b. All HDMI 1.4b products will continue to be tested to CTS 1.4b standards. HDMI 1.4b adopters cannot also be licensed to the HDMI 2.1 specification.

 

As an HDMI Adopter, L-com offers a wide selection of HDMI certified cables and HDMI Splitters/Extenders.

For Your Viewing Pleasure: HDMI 2.0

September 24, 2015 at 8:00 AM

 

The next generation of TV’s will continue to raise the bar to improve your viewing experience. New high-resolution and frame rate requirements have led to the creation of the next generation of high-definition multimedia interface, HDMI 2.0.

 

To meet the increased bandwidth required by next generation TV's, HDMI 2.0 supports 2160p up to 60fps. This allows for full-resolution 4K 3D coupled with higher frame rate 2D content, including PC-based video games and home videos.

HDMI 2.0 increases the size of the "conduit" between the TV or display and the transmitting source, such as a Blu-ray player. This allows for higher frame rates at higher resolutions compared to the previous version, HDMI 1.4. Plus, HDMI 2.0 devices DO NOT require new cables to function! This means you can avoid forklift upgrades of your cabling infrastructure when implementing new HDMI 2.0 products!

L-com manufactures a wide selection of HDMI 1.4/2.0 Cable assemblies. From consumer-grade to industrial armored versions, we offer one of the widest off-the-shelf selections available anywhere. As a certified HDMI adopter, all of L-com's HDMI cable designs are tested and approved by HDMI Licensing LLC.


Here are some of the features HDMI 2.0 supports:

 

  • - 4K@50/60, (2160p), which has 4-times the clarity of 1080p/60 video resolution
  • - Up to 32 audio channels for a multi-dimensional immersive audio experience
  • - Up to 1536kHz audio sample frequency for the highest audio fidelity
  • - Simultaneous delivery of dual-video streams to multiple users on the same screen
  • - Simultaneous delivery of multi-stream audio to multiple users (up to 4)
  • - Support for the wide-angle theatrical 21:9 video aspect ratio
  • - Dynamic synchronization of video and audio streams
  • - CEC extensions provide expanded command and control of consumer electronics devices through a single control point

HDMI 2.0: Enhancing Your A/V Experience

October 30, 2014 at 10:00 AM

 

When you sit down to watch Sunday night football this weekend, consider this:

 

Next generation TV's and displays are requiring higher and higher resolution and frame rates for enhanced user experience. Every time we turn around, the view from the TV, or camera, or video screen looks better and better.

 

How is it that HD is so clear, it’s as if we have cleats laced on our feet, our pads crunching and crackling against the opponent’s offensive line…

 

Well, to address this higher resolution demand, High Definition Multimedia Interface technology from the HDMI Forum released its latest interface version, HDMI 2.0.

 

HDMI 2.0 uses 2160p and up to 60fps which allows for full-resolution 4K 3D, coupled with higher frame rate 2D content, to support applications such as PC based video games and home videos. These benchmarks also meet the requirements of more bandwidth for those next gen TV's.

 

One of the most important features of HDMI 2.0 is the increase in the size of the "conduit" between the transmitting source (such as a Blu-ray player) to the TV or display. This allows for higher frame rates at higher resolutions compared to the previous standard, HDMI 1.4.

 

To sum it up, the important features and advantages of HDMI 2.0 include:

 

-4K@50/60, (2160p), which is 4 times the clarity of 1080p/60 video resolution
-Up to 32 audio channels for a multi-dimensional immersive audio experience
-Up to 1536kHz audio sample frequency for the highest audio fidelity
-Simultaneous delivery of dual video streams to multiple users on the same screen
-Simultaneous delivery of multi-stream audio to multiple users (up to 4)
-Support for the wide angle theatrical 21:9 video aspect ratio
-Dynamic synchronization of video and audio streams
-CEC extensions provides expanded command and control of consumer electronics devices through a single control point
 

Another detail to consider is that HDMI 2.0 devices DO NOT require new cabling or connectors. HDMI 2.0 devices will use HDMI version 1.4 cabling and connectors.

 

L-com manufactures an expansive selection of HDMI 1.4/2.0 Cable assemblies. From consumer grade to armored industrial HDMI cables, we offer one of the widest off the shelf selections available anywhere. As an HDMI adopter, all of L-com's HDMI cables are tested and approved per the HDMI Forums standards.
