  • Analog sunset begins, all the new Blu-ray players will only output HD via HDMI

    The chicken littles have been worried about this since long before the first Blu-ray (or even HD DVD) title was ever released, and the first step towards the analog sunset has officially come. Any new Blu-ray player announced after January 1st 2011 will only output HD via HDMI -- players that started shipping last year can still be sold until the end of this year though. If you just love component video, you might figure you'll be able to get a player today and continue to enjoy it for years to come, but maybe not. You see the studios also have the Image Constraint Token (ICT) which when set on a title will tell every and all Blu-ray players to down convert analog output to 540p. The only reprieve is that if its set on a title, it must be marked on the box, and of course it can't be retroactively set (any title you own now will continue to play exactly the same way it does on your existing players). We're waiting for final confirmation, but apparently the ICT hasn't been an option to studios until now so start looking for the icon on your latest purchases. The final stage in the sunset is 2013 when analog outputs will be removed from Blu-ray players completely, but we suspect we'll have better things to worry about by then like ultra HD or digital distribution.

  • CableCARD recordings and Blu-ray play at full resolution over analog outputs

    Yes we know this is not news, but you'd think it was based on the various stories around the web like this one from Yahoo Tech. We don't mean to pick on this one specifically because honestly it is a very common mistake -- although this particular article is way off as the newer Macs do support HDCP -- but as draconian as CableLabs and the AACS can be, the analog hole is still open. Now that doesn't mean these DRM requirements aren't crazy or that this protected path we always hear about is a joking matter, but it is all for naught when the HD signal hits the analog outputs -- the digital outputs do require HDCP though. This means you can watch any Blu-ray Disc or digital cable program recorded with an ATI Digital Cable Tuner at full 1080i via VGA or component -- Blu-ray Discs can be played back at 1080p via VGA but component doesn't support it. Now we're not trying to say this will always be the case, as both technologies support down-rezzing via analog outputs, but as it stands now these bits have never turned on. Now to the main point of this particular article, which is why Macs don't have a CableCARD option. Our best guess would be that Elgato doesn't want to pony up the $200k for the CableLabs certification process and honestly we don't blame 'em.

  • PS3 add-on allows full HD resolution for Blu-ray on DVI

    For those gaming on popular computer monitors with non-HDCP DVI inputs, a gadget has been released that allows a workaround of HDCP protocols, allowing Blu-ray movies to play at full resolution on these displays. If you're a bit confused about the protocols of HDCP and how it all works, you are not alone. High-bandwidth Digital Content Protection (HDCP) allows content providers to prevent the full resolution of products (Blu-ray or HD-DVD) by crippling the resolution on displays where the HDCP handshake fails. Technically, all parts of the chain need to be HDCP-compliant in order for the full resolution to process. For an HDMI connection, HDCP would spring to life when an HDMI-DVI adaptor is introduced to a non-HDCP compliant DVI port, forcing the resolution to 540p at best. The introduction of such a gadget is a welcome addition, allowing users to view the content they paid for, even though the mere fact consumers have to revert to such methods is downright infuriating. Thankfully, with ICT not being an issue until 2010, PS3 owners can enjoy Blu-ray content via HDMI, analog (component) and now, all forms of DVI. Lets hope the ICT mess gets figured out sooner rather than later, so we can get back to awaiting the latest Blu-ray releases without the fear of having high-def viewing pulled out from under us.[Update: Edited post to point out this gadget is most useful for non-HDCP compliant DVI inputs. HDCP DVI inputs will not limit the resolution to 540p as suggested. Thanks!][Via Kotaku]

  • No HDMI on PS3 not a problem until 2010?

    When Sony announced a cheaper, $500 PS3 there was some confusion as to what features would be removed; confusion that both we and Sony tried to clear up. Ultimately, the only non-upgradable feature: HDMI. Naturally, the majority of consumer confusion has centered on this particular omission and whether or not the PlayStation 3 will support 1080p without an HDMI output. The answer came down to whether or not the content being displayed contained the Image Constraint Token, which would require an encrypted digital connection (using HDMI) to display the full "True-HD" resolution of 1080p. Without HDMI, your fancy new Blu-ray player would be forced to playback your fancy new Blu-ray discs at a measly 540p. Why hasn't Sony taken any steps to quell the rampant speculation, fear, and misinformation floating around the internets regarding their decision? Well, the answer's simple: they're not sure themselves. Last week Sony announced they would not be downsampling analog connections with their own content, but will the other content owners (read: movie studios) follow suit?According to recent internet scuttlebutt from reputable German site Spiegel (machine translation), top secret negotiations between a very grumpy Hollywood and some tech giants (including Microsoft and Sony) are looking to delay implementation of the ICT until 2010 or even 2012. This of course helps explain the baffling absence of HDMI on the cheaper PS3 (and Sony's heretofore baffling silence on the issue), and the ongoing absence of an HDMI output on the Xbox 360 (despite what Lik Sang lists).[Thanks, Fan; via Engadget]
