Hdmi forum announce new spec…do we need 8k/10k Video?

The holiday season is upon us with many people starting to go out and purchase 4K tv’s as the technology is starting to become affordable for most of us. however just as this happens we now see the HDMI (High-Definition Multimedia Interface) Forum have looked into the future and give us more to think about with a new standard of the HDMI standard, version HDMI 2.1.  The latest specification will allow up to 10K resolution with Dynamic HDR, an ultra high-speed HDMI cable specification with up to 48G bandwidth to allow uncompressed content.

A few specifications from the HDMI forum to understand what is new in this version of HDMI

Full resolution and frame rates include:

  • 4K50/60
  • 4K100/120
  • 5K50/60
  • 5K100/120
  • 8K50/60
  • 8K100/120
  • 10K50/60
  • 10K100/120

Feature highlights of the new specification as well:

  • 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:
    • Variable Refresh Rate (VRR) reduces or eliminates lag, stutter and frame tearing for more fluid and better detailed gameplay.
    • Quick Media Switching (QMS) for movies and video eliminates the delay that can result in blank screens before content is displayed.
    • 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.

So do we need this higher resolution, well in the pursuit of getting to a quality of what we see then yes, but currently will we see a difference, this is hard to tell without actually seeing 10K content on a screen, but assuming we saw the differences from 480/576 to 4K I would expect the picture clarity to improve again.  Much like the audio world we have seen the resolution of audio increase with technology from analogue audio to 14bit 44.1Khz CD players(Phillips original standard) and now today we have 24bit/192Khz and above resolution recordings and technology to pack this content, technologies such as MQA. so in the audio world, we have seen the evolution and I see this now happening with video.  I have had many people over the years discus they cannot hear the difference between 16bit/44.1Khz recordings compared to 24bit/192Khz recordings and many people who can, so I expect I will hear similar conversations about the video and it will be up to the individual.

So do we need it, well we might not but the tv manufacturing industry does to survive, it needs to continue developing tv technology from black and white CRT to flat screens to HD technology, ambient lights, 3D, curved and now 4K so we see these technologies make us all go out and by new TV’s so we have the latest technology. For me, I still have my 2007 model 42″ Pioneer Plasma Kuro (720p only)  which cost around £1900 in 2007 but was the best around for picture quality and is still a very good TV, it will be replaced but it serves me very well and maybe I will hold off for one of those new 10k versions.

New iPhone X

 

iPhone X

iPhone X

A couple of weeks have passed since my upgrade to the new iPhone X (pronounced as iPhone Ten). lots of people have asked do I like it, how does it work without the home button and the main one does Face ID work without issues. I purchased on 02 Refresh as a long-term customer the iPhone X 256GB version which is the largest you can get with a cost of £1,149.00 the trade-in of my old phone meant my 12months left of my previous contract was paid off.

 

Well, I can say Face ID works fine, it is quick and easy, however, I do find sometimes that I personally don’t register it has authorised and I need to swipe up, mostly because it is quick to unlock.

Not having a Home button, takes a little time to get used to, slightly different ways on how you need to shut down apps and do things but these are easily learnt.

Another question I am asked does the black knock out detract at the top of the screen, actually, I don’t notice it and am not put off by it.

The phone is fast and being something I use heavily I have not found any issues with it.  The display is amazingly good and the camera is brilliant as some of the photos I have recently taken are better than I could take on my old Canon SLR mainly due to the dual camera sensors and improved processing.   The main issue I have is battery power on all phones but this one seems to be good, however, the iPhone 7s plus is marginally better.

Wireless charging is really good and the Belkin wireless charging base is really good.  I would like to see what the Apple one is like but that will not be available until 2018, so we will wait and see.

I think the thing for me is that yes most of the technology included in the phone is not new or groundbreaking but that’s not what makes these phones so good.  Apple has built an ecosystem with the operating system which now integrates with all my Apple products, changing a phone is pain-free if you use iCloud backups as you can re-import a backup and be back to right where you were before the new phone with all your details saved.  I have been playing with android too as I have a spare phone but I just cannot get into the android mentality and I seem to get frustrated with them. maybe it is due to using Apple for so long that I need to think about it in a different way.  So I will not be moving anytime soon from an Apple phone.

Marseille 15th November 2017

Fortunate to fly out to the south of France to Marseille with work to survey another super yacht. I seem to be spending a lot of time recently traveling to meet some of these lovely yachts. This time its a 76m yacht which we have previously done work on. This time it is a matter if surveying for further works. First time in Marseille but not much different from any other South of France location. A Big port with a good airport, I flew in while it was dark but the view across the city was beautiful. The airport is a bit like when you come into Nice where the planes come in off the coast directly onto the runway.

Not many photos except 2 both from the airport looking across to the sea. I was getting on an easyjet flight which was not too full for once.

Palma November 2017

A work trip led me out to Palma, Majorca. It is a nice city and it has been a few years since visiting on a holiday. It has all the charm of any Spanish city and some very good food places. I am due out again later in the month for around 5 days so will get more of a chance to see more and eat at a few more places.

Starting a Blog…..again

Well, this is the start of writing a blog….Well restarting

The question I ask myself and I am sure others will ask is Why? Well, it is simple really. I travel quite a bit I work with new technology and seem to gain knowledge and experiences throughout the year. I always have an iPhone with me and tend to take millions it seems of photos which only I really see, some of which I cannot share due to client confidentiality but there are many I can and should share.

This year has been pretty manic especially the last few months and I need to start balancing my life up a bit. More play and less work but we will see how that goes.

Anyway, I will keep this short and sweet and hope my new blog will start to really record all the trials and tribulations of my life in general.
