This week, there has been a lot of publicity about the first recording of Alexander Graham Bell’s voice, an 1885 disk, finally being heard thanks to the latest technology. But there was an earlier recording, and it was heard in 1937. The headline of the story in the October 28 issue of The New York Times that [...]

John Huntington posted a comment on my “Late–and See?” post about latency and lip sync.  It includes this link to a video that illustrates very well the speed of sound: http://controlgeek.net/2009/1/21/seeing-sound-waves.html

I’ve posted a comment to the story that implies that the movie Hugo cured someone’s stereoblindness.  But the person was never stereoblind.  Here’s more from Professor Banks: “The data show quite clearly that Bridgeman had stereo but that his thresholds were not normal (that is, his stereo vision was reduced, but certainly not absent).  ”We have [...]

In a previous post, I described the Tessive Time Filter, subject of a presentation and demonstration at February’s HPA Tech Retreat.  John Watkinson submitted a comment on it, and Tony Davis, Tessive’s founder, responded.  First, here is John’s comment: The Tessive LCD shutter Numerous claims have been made for this device which I consider here.

In my post “Satellites Are Really Old,” I distinguish between the Emmy-winning first commercial geostationary satellite, Early Bird, and the earlier non-commercial Syncom III. Was the “commercial” distinction Emmy-worthy? Here’s a link to a story about how the 1964 Tokyo Olympic Games coverage was delayed in the United States precisely because it was carried on a [...]

The originally posted version of “The Best 3D Conference” indicated an apparent conflict between Mark Lucente’s and Michael Bove’s statements about the beginnings of holographic video. Lucente has pointed out that he was referring to work on actual displays, whereas Bove’s earlier date referred to the theoretical. Lucente’s comments have been appended to the bottom [...]

Based in part on the post here <http://www.schubincafe.com/?p=3303>, The New York Times on February 27 corrected its January 9 column on headphone history <http://www.nytimes.com/2011/01/09/magazine/09FOB-medium-t.html>.  The comment about their not correcting their story, therefore, has been removed from my post.

An early version of the post “125th Anniversary of Pay Cable” said Sunrise at Campobello was written and directed by Dore Schary.  It should have said it was written and produced by Dore Schary.  The director of both the play and the movie was Vincent J. Donehue.

As Blu Laser Digital commented on my recent 3DTV Today post, there are non-broadcast modes in the HDMI 1.4a specification that allow full spatial resolution for both views.  For 1920×1080, however, that mode is only for 24-frame-per-second (or 23.976) material.

Every Tuesday, the “Really?” column in the Science Times section of The New York Times explores an issue to decide whether it’s myth or fact.  Today’s topic, by Anahad O’Connor, was, “The Claim: 3-D Movies Can Induce Headaches and Sickness.” “THE BOTTOM LINE 3-D movies can cause unnatural eye movements that induce strain and sickness.”  Here’s [...]

“And the award goes to…” The Academy of Motion Picture Arts and Sciences has announced that one of its latest Scientific and Technical Awards will go “to Dr. Klaus Anderle, Christian Baeker and Frank Billasch for their contributions to the LUTher 3D look-up table hardware device and color management software.” The three dimensions, in this case, refer [...]

Rafe Needleman writes of his stereo blindness in cnet news and of watching Avatar in a 2D auditorium: http://news.cnet.com/8301-19882_3-10435478-250.html But, at home, where some viewers might want 3D and others 2D, 2D viewing might not be an option without 2D glasses. The piece also includes this interesting sentence: “Bruce Berkoff of the LCDTV Association and formerly [...]

Besides yesterday’s article in the UK Telegraph, today’s New York Daily News has a similar story: http://www.nydailynews.com/lifestyle/health/2010/01/12/2010-01-12_little_too_reelistic_mega_3d_hit_avatar_giving_some_motion_sickness.html

In the first version of my post Sines of the Times, I incorrectly stated that in a right triangle the sine was the ratio of the side opposite the angle to the side adjacent to it.  That’s actually the tangent.  A sine is the ratio of the opposite to the hypotenuse (the side not touching [...]
