Sorting Out HDMI Version Upgrades for 3D – The latest HDMI v1.4a spec is designed to accommodate all 3D video and audio formats and theoretically will work with any new home AV products offering HDMI 1.4 inputs and outputs, although suppliers should confirm for themselves. The HDMI 1.4a spec supports both side-by-side horizontal and top-and bottom 3D displays at 720p, 1080p or 1080i resolution. The frame-packing format for 720p is just under 60Hz and for 1080p just under 24Hz. Although AVRs will have to allow pass-thru or repeat of any of the 3D formats, various source components need only support one of the 3D formats.

Book Collects Best of Former Cassette-Tape Magazine Speaking of Art, from Phaidon Press, is a small sampling of the immense undertaking of William Furlong in the early 1970s, when he began to harness the lowly audiocassette for conversations with artists, when none of that talk was being met by any of the traditional arts publications. He recorded on 5-inch reels on a little Uher portable tape deck and then edited the converstions – more informal than typical interviews – into 60 or 90-minute portions for distribution on audiocassette. It came a sort of monumental audio sculpture, that got more attention in Europe than in the U.S.  Some of the conversations were with artists such as Jeff Koons, Josephy Beuys, Andy Warhol, and Richard Serra. Furlong says he probably wouldn’t push the record button again now because it’s so difficult to spend time with the artists. It’s become such a business that “I have to go thru so many PR people and gallery gatekeepers…I just got fed up with that.”
