Author Topic: 4K vs. 2K - Do you see better image quality? Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 07-22-2004 11:01 PM                     I'll try to find out what the exact reason is for the 1080p thing. Its not even a standard as of yet. I can say that its much harder to tell differences in resolution with a crt based imaging device as you are starting to get to the spot size limit that the electron beam and phosphor formulas are able to do. With 1080i you are approaching the limits that even a very high end crt can do. In the next 10 years we will not only see 4x3 screens disappear but we will also see CRT's disappear as well. CRT's are very costly to produce and costly to design and build the support circuitry for. Governments are beginning to require them to be recycled because of toxic ingredients that go into them. With more and more mass production of solid state imaging reproduction systems(lcd, dlp, etc.) there is definately alot of incentive to head these routes.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 07-23-2004 08:07 AM                        quote: Mark Gulbrandsen Governments are beginning to require them (CRTs) to be recycled because of toxic ingredients that go into them. AFAIK, the big environmental issue with CRTs is the use of lead for shielding any x-rays produced. Also chemicals like thorium, barium, or strontium that may be used on the cathodes. Of course, lead solders have long been an issue with electronic components, as well as other "nasties" like etchants and solvents used in IC and circuit board production, cadmium, chromium, thorium, etc.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

The defined HD standards are 480p, 720p and 1080i though many things accept 1080p. Michael, how were your feeding your DP50 720p and 720i signals? What was your source equipment?

I have to go back and check the output options of the receiver, maybe I remember that incorrectly. I may have confused it with 480p/i, I did a lot of experimenting with that setup.  |  IP: Logged Robert L.

SONY UNVEILS MARKET-READY SXRD 4K RESOLUTION PROJECTOR FOR NEW ERA OF DIGITAL CINEMA Sony is heading into the ShowEast convention in Orlando following a successful unveiling of the market-ready version of its digital cinema SXRD™ (Silicon X-tal Reflective Display) 4K projector. Ushering in a new era in theatrical exhibition, the professional front projector (model SRX-R110) started shipping earlier this month, and Sony intends to begin producing 100 units per month by December. During a day of movie industry screenings last week in Hollywood, Sony showed a variety of 2K and 4K footage, highlighting the unique capabilities of the projector. Content screened included “Mystic India,” “Star Wars Episode III: Revenge of the Sith,” “The Sound of Music” and material from the DCI and ASC Standard Emulation Material (StEM). The footage was presented in both 4K and 2K resolution, as well as in side-by-side comparisons with a 2K DLP projector. On hand for the demonstration were representatives from major Hollywood studios, independent production companies like Lucasfilm and Lightstorm, leading post houses and industry organizations such as DCI and ASC. Exhibitors, including Landmark Theatres, the first major chain planning to roll out SXRD, were also in attendance at the event, held at the AMC 16 Theater in Burbank, Calif. “We are very gratified by the reaction of the entertainment community,” said John Scarcella, president of Sony Electronics' Broadcast and Business Solutions Company. “The industry response confirms our belief that 4K technology presents a distinct advantage for the theatrical exhibition community.” Thirty-three years after Sony introduced its first electronic projection system, the KP-7200, the company maintains its position as an industry leader and innovator. The SXRD 4K projector offers superb contrast, vivid color, and 4096 x 2160 pixel resolution, which displays images at nearly four times the resolution of current high-definition displays. The new SRX-R110 model is specified at 10,000 ANSI Lumens and is designed for screens up to 40 feet wide. “The progress made to date is impressive,” said attendee Michael Karagosian, a partner of Karagosian MacCalla Partners. “The display of the media block card was unexpected and very welcome. This is a central element toward a digital cinema-centric solution.” Sony plans to follow up the debut screenings with another round of demonstrations at this week’s ShowEast trade show in Orlando, Fla. In addition, a request will be made that NATO organize and set specifications for a side-by-side test of 2K and 4K technologies and work in conjunction with the Digital Cinema Lab/Entertainment Technology Center and the ASC to set parameters for these tests. Following ShowEast, Sony will present a white paper at SMPTE/NY on the latest developments for SXRD 4K front projectors.  |  IP: Logged Mark J.

I wonder how it looked.  |  IP: Logged Darryl Spicer Film God Posts: 3250 From: Lexington, KY, USA Registered: Dec 2000 posted 10-25-2005 07:40 PM                    do we really want anything with Sony's name on it.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

So if Sony does't make significant inroads in the video projector market are they not only going to pull out but also make servicing them a nightmare (prohibitively expensive)?  |  IP: Logged Oliver Pasch Film Handler Posts: 53 From: Europe Registered: Jun 2002 posted 10-26-2005 07:29 AM                    quote: Paul Konen is designed for screens up to 40 feet wide. In the rest of the world, that's just a little more than 12 Meter. So we're talking about the smaller, if not smallest auditoriums in todays multiplexes here. Who need's that? Who want's to open the blockbuster of the week on his smallest screens? SIZE DOES MATTER! The only good thing is, that this might give SDDS a new meaning... Small Damned Digital Screen ...or DTS... Digitally Tiny Screen No offense against any soundformats here intended!

I would think that just getting the Sony name in front of audiences would be a great brand-building tool for selling TVs to consumers. Technically though, ya gotta admit the Sony cinema system is intriguing.  |  IP: Logged Ron L.

I still see the logo on the end of films along side of the Dolby Digital and DTS logos but where is the need now? I mean other than those unlucky enough to have SDDS sound systems!  |  IP: Logged Lyle Romer Phenomenal Film Handler Posts: 1400 From: Davie, FL, USA Registered: May 2002 posted 10-26-2005 11:52 AM                     David, Sony's pockets aren't as deep as they used to be. They've been in a lot of financial trouble recently to the point that bankruptcy has been a topic of discussion on the financial channels.  |  IP: Logged
