Yeah I'm a bit annoyed they haven't ditched the pointless HDCP for 1.4 too, Phil.

[kingfats]

Jeff Boccaccio seems like a decent chap explained HDMI v1.4 nice and clearly as well.

He looks a bit like Jim Bowen.

Pointless? Try telling Hollywood it's pointless!

[eiren]

Well anyone that wanted to defeat it could just use relatively inexpensive HDCP strippers... so it's not very effective, and annoying for everyone else when it causes all the issues it does with hardware incompatibility.

Not to mention the very loose implementation of the HDMI specs that many manufacturers seem to employ

[davepuma]

As ever Jeff explained it excellently and it has cleared up a few issues I had in my mind.

Thanks AVF!

[IAN P]

At 4.08 the guy clearly states that all HDMI cables will give the same pic quality, now we've all been down this road before haven't we?


Send him to What HI-FI and ask him to explain to the staff there what cobblers they're spouting.

100+ notes for an HDMI lead, err, no.


Excellent video by the way.

[namuk]

Nice one, explained well

[BISHI]

I am asuming that the interviewer was in house equipment reviewer Phil Hinton.............. nice to put a face to the reviews...

[Pecker]

What a genuinely nice chap.

Reminds me a little of Artie Fufkin from This is Spinal Tap.

A really useful video. Thanks.

[weyland-yutani]

1.4? what was wrong with 1.3?

*watches video

oh!

[rigman]

Great video thanks to Jeff and Phil for sharing it.

[Figment]

Did anyone ever get an answer to the question of why these videos will not play on an ipod touch when downloaded via itunes? I have seen this question asked several times but have yet to see a response. I have the same problem and cant watch any of these.

[CAS FAN]

A great video which explained the benefits of 1.4 well. It's good to know that it will be backwards compatible on the whole and whilst most of us all knew it, it's good to here an expert confirming that there's no difference between different quality cables.

That said, some people will still say there is .

Yes indeed! Something the majority of people here knew or suspected already but as you say, some will no doubt still insist that they can see a difference!!

[eric pisch]

so i need to upgrade to £100 hdmi 1.4 leads to get the best out of my current system







good interview phil

[Ryu]

At last from the horse's mouth - all HDMI cables provide the same picture quality. Now someone tell Currys!

[Synchro]

Network over HDMI, Thats put the cat amongst the pigeons lol

[Maximinimus]

Thanks

[DodgeTheViper]

Excellent interview from Geoff, with some good questions from Phil

This all I need. Won't be long before each film will want to dial home to allow you to watch it.

You'll only be able to watch a film on your registered player. No lending. If you change your TV or sound system you'll have to reinstall something. Just like a PC. The DRM will go the same way as games. EVIL EVIL STUFF!

[DR Kronenbourg]

ok guys, ave watched the video and am particularly interested in the reverse audio side of this cable, now i am a complete novice and by your posts you all seem to understand these cables way better than i, what i would like someone tell me is will this cable return the sound of my digtal tv (normal tv not DVD) back to my avr allowing me to listen through my surround sound? and if so is there going to be a compatabilty issue when it comes to certain TV sets or will it be as simple as if it has HDMI it will work. i'm near sure in my mind that this just sounds way to simple and i am probably miles out on how this works, any help on my understanding of this would be greatly appreciated.

[stubie_do]

All great but at least an Ethernet cable stays in the socket. How many times have I been on site to plug an HDMI cable back in I now go with Gaffa Tape.

Plus there is no difference between a £1 HDMI cable and a £1000 one.

HDMI 1.4 is a very bad upgrade to HDMI 1.3. They're going to be creating new hardware for HDMI 1.4 and all it has is the exact same bandwidth as HDMI 1.3. They allow an increased resolution, at 4096 pixels across, but only at 24 frames per second when HDMI 1.3 can do 60 frames per second at 1080p (in fact HDMI 1.3 allows 2560×1600p at 75fps). That will be no good for many things. Super Hi-vision is higher resolution - 7680×4320 at 60 frames per second.

They could have gone and created a proper new, good standard that allowed much better things, including higher frame rates as well as resolution and much more - like variable frame rates and much more resolution options and tons more stuff.

surley it can still do 60fps at 1080p ?

its down to the movies makers to stop using 24fp its old hat and too slow.

also, chill out there will ALWAYS be newer better stuff, HDMI 1.5v will be around the corner and it will do 75fps and 4k res with deep colour 2, and 3d capability.

speaking of 3d capability i thought you needed 120fps with 60 fields per eye ?



lol at what-hifi and currys. it should almost be a crime to sell £1k HDMI leads.. somebody please link this thread to a what hi-fi forum

I'm sure it will, but it's just a wasted opportunity. We'll have to go through a new hardware cycle where everything is "hdmi 1.4" this or that, yet it's still the same bandwidth as the old standard. If there are any higher resolution displays that would benefit from the higher supported resolution, they'll have to cut the frame rate down to 30 (if sending 3840 across) or 24 (if 4096 across), which like the BBC says will make things worse for TV picture/motion quality. So any super high res displays won't be able to use it for things like live TV which is >30fps eg. for the 2012 Olympics.

its down to the movies makers to stop using 24fp its old hat and too slow.

Nothing will be able to be >24fps at 4096x2160 using HDMI 1.4. Live TV would need to be 24fps, computer displays, games consoles, sports, concerts, everything as well as movies.

also, chill out there will ALWAYS be newer better stuff, HDMI 1.5v will be around the corner and it will do 75fps and 4k res with deep colour 2, and 3d capability.

True, but we'll have to go through this set of products where everything is HDMI 1.4 and that's promoted as the thing you need to have. If high res (eg. 4096x2160) displays or playback devices do become available during the lifetime of HDMI 1.4 they'll be limited to that, and they'll promote those displays and discs as being "4K" without mentioning frame rate like they do now, and it'll make lower resolution but higher frame rate sound worse, as well as limiting what content producers can release.

speaking of 3d capability i thought you needed 120fps with 60 fields per eye ?

Yes I think the TV needs to accept 60x2 (120) frames? per sec though I think different 3D displays might use different methods, but HDMI 1.4 is supposed to make sending 3D to a display more standardised, but the BDA still haven't decided on the 3D standard for Blu-ray yet.

thnx

This is quite telling. Somebody posted on What Hi-Fi forums today to point people to a YouTube video of this interview. This post was removed, apparently because it pointed people to a rival publication.

In reply, I asked if I could instead post quotes by Jeff Boccaccio, specifically his quotes on HDMI cable quality and its impact on picture and sound. My post was removed because apparently I'm not allowed to discuss moderation. How exactly was I discussing on moderation?

Apparently What Hi-Fi do not allow posting of comments attributed to leading HDMI experts.
