As some Iomega customers found a year or so back, the DLNA compliance of their new network storage devices didn't ensure that the movies they placed on them would play back on their DLNA-compliant Sony TVs.
Nidhish Parikh, newly elected chair of the DLNA, whose day-job is head of personal media at Nokia, admits that DLNA is still work in progress. “We’ve done a lot, but there’s a long way to go... We’re being very responsible and deliberate in what we’re trying to do here.”
DLNA is a standard feature of Windows 7. Older versions can be brought up to speed by installing Media Player 11
Evidence of this “deliberation” emerges from the Alliance’s approach to mobile data. Twenty-first Century lives are no longer centered around the living room, so media servers like the Pogoplug - none of them DLNA-certified, incidentally - offer streaming to mobiles and other devices across the internet.
The Alliance has just this sort of wide area network functionality in its telescopic sights, but is waiting for the general deployment of IPv6. But as Jed Putterman, of Pogoplug developer Cloud Engines, reminds us: ”Even the beginnings of IPv6 acceptance will be years away.”
But what can you expect from an organisation founded in 2003 but which in 2010 still can't guarantee member A's products will work with member B's? The Alliance finally announced this year that it will put in place a system to certify DLNA-capable software, but it has yet to reveal any details about the scheme.
Confined for now within the home network, DLNA offers consumers a generalised assurance of multi-media interoperability. But the fine details of what it actually does - and doesn’t do - lie behind paywalls on the DLNA Web site. And because the Alliance doesn’t offer any central help desk, when your cross-manufacturer connections fail, there’s no single point of redress - which, of course, may be one of the reasons DLNA goes out into the marketplace under various brand disguises. ®
Next page: How DLNA stacks up
I didn't vote you down, but I expect this comment may have had something to do with it..
"because your TV won't play your pirated videos."
bit of an assumption there, b'aint?
Half right, I'd say
It's true that many TVs (and other playback devices) are decidedly lacking in format support. But I do think it's still appropriate to blame DLNA for at least part of that.
Most of us here are technical, and understand all the complexities and interactions involved. But ordinary punters are not. And if DLNA is to mean anything useful, then it should surely be some guarantee of compatibility beyond just "yep, I can probably show you there's a server on your network."
The point of marks such as these, from the view of the novice consumer, is to make things simple and to make it easy to make purchasing decisions. DLNA ought to guarantee that when you buy a TV with the DLNA logo, and connect it to a network on which you have a DLNA server, you can access if not all, then certainly the vasty majority of your media.
You can lay the blame at the door of the TV makers, or the software, or wherever you like.
But ultimately, as far as the consumer is concerned, it is the fault of DLNA, which paints an image on its own website - just look at http://www.dlna.org/digital_living/possibilities/ - that is far removed from the reality experienced by many consumers.
If an organisation say "DLNA Certified® products are built to work together, even though they come from many different companies" and that turns out not to be the case, then I think it's pretty fair game to blame the organisation.
OK, not really, but seriously how can you have an article mentioning Boxee but not the much more popular system it's derived from (XBMC)?
Does Boxee have significant DLNA functionality that doesn't exist in XBMC? I haven't seen anything to indicate that. Boxee's selling points vs. XBMC, as far as I can tell, are the social/Web 2.0 aspects of its interface, the new/forthcoming release of the Boxee Box (or whatever it's called) which means you can put it in without building your own HTPC or hacking an Apple TV, and *maybe* integration with Hulu (but not, AFAIK, Netflix). Everything else XBMC does just as good if not better.
Not trying to knock Boxee or rake El Reg over the coals too much here, but AFAIK XBMC is significantly more popular and if you're going to mention one you should probably mention the other too.
That said, TY for the article - this is an obscure but increasingly important subject now that just about everything AV is coming with an ethernet jack in the back these days.
DLNA is for geeks only
DLNA is in no way ready for the mainstream. I've been posting on AVForums for years both giving and getting help with DLNA, and the best conclusion that I can make is that you will always end up hitting at least one hurdle, but more than likely several.
My best advice would be - find out what formats your renderer supports and encode/transcode to those formats from the outset. This is especially true for NAS devices that don't have the muscle to transcode on the fly.
What's particularly annoying is that a lot of renderers will play back media from a USB device, but will not play it back over DLNA (e.g avi files on Bravia TVs).
UPnP in AV equipment still requires you to enable UPnP on your router's firewall which means your DNLA equipment can happily go punch massive holes through your firewall without your knowledge. Once you've enabled UPnP just to get your AV services to work, you're open to vulnerabilities on your PC from malicious web sites and apps that can punch holes in the firewall.
No chance UPnP is getting enabled on my network.
