My World Cup Passive 3D nightmare

I have been into 3D for awhile now, so I like many others jumped at the chance to watch ESPN"s 3D coverage of the FIFA world cup games.

What I found out stunned me. It is virtually impossible to watch the world cup broadcast on a 3D TV using Passive (circular polarized) content, WHAT?? It seems that the initial 3D broadcasts are only being geared towards the lower cost active displays made by Sony, Samsung and Panasonic.

It seems that the 3D content sent by DirectTV is 720p60 in a signal called "checkerboard" for those of us that actually work in 3D that translated to "interlace".
Great I get that, however the problem I ran into is 2 fold. I tried connecting with with 2 different displays, both leaders in the field for passive technology. JVC's GD-463d10 display is one of the best out there, in spite of the nearly $10,000 USD price tag and a Hyundai model that cost over $5000. Damned if I could get either of these sets to work, and both for different reasons.
Those that keep up with my diatribes know that I dearly love the JVC display and it was everywhere at this past NAB, the one issue with this set is well one of those things that is more annoying than I ever imagined. It does not accept a 720p signal, that's right JVC's cameras shoot mostly 720p but the stereo display they designed cannot see the signal from there cameras, and because the HDMI broadcast signal uses HDCP I could not use the trick I used at NAB- passing the 720p signal thru a KiPro to cross-convert the signal to 1080. The HDCP protocol limits the devices that process the HDMI ( no aja device allows you to violate the HDMI hardware restraints).

So I moved on the the Hyundai display, I have used these onset, and while the set allows the 720p signal - low and behold- the Hyundai display does not support the "checkerboard" signal being sent by DirectTV.


Let me say that I was not brought in to assist with the issue until someone at the facility had spent more than 15 hrs trying to fix this issue first, I spent another 5 hrs,before I had tried all of the available options ( including one from Hyundai that called for using a $129 Geffen box to modify the HDMI signal.

Oh well back to 2D

Cinegear 2010

I am setting at LAX on my way back to Chicago after spending the weekend at CineGear, the onset production show, held for the last 2years on the Paramount Studios backlot and stages. This is the acquisition show, cameras, capture and the associated tools. Cinegear for me is not a selling show - it iwas for me the ultimate schmooze fest, a place where I can actually get a chance to talk to some of the people that I only get to wave at as I zoom by their booth while I am running from one meeting to another at NAB.

It is also a time when the industry comes together. I attended a BBQ last night at the unbelievably beautiful restoration of the ASC clubhouse in hollywood. Now bovines think about being outside on a wonderfully cool LA evening with friends like Bob Primes jASC, Dave Stump ASC, Michael Bravin, and industry luminaries like former head of ARRI Volker Banderman, and every name ASC member I could think of (except my friend Roberto Schaefer ASC) all rejoycing in the great history of this building.

Then I headed over the CML party being held at Birns &Sawyer to hook up with the ulitmate industry tech group.

I cannot tell you how much fun it is to be standing in the middle of a parking lot / swimming pool / shooting tank on the Paramount lot when a Very very well known DP stops to join in my conversation with a couple of other people then stops the conversation to tell me he loves reading my stuff on the cow. I will not name him publicly because I was asked not to, but nee lees to say it inflated my ego for a couple of hours.
