Mark Schubin Publishes 4K TV Primer at SchubinCafe.com

Aug. 31, 2011 - PRLog -- Mark Schubin, multiple Emmy-Award winning TV engineer, consultant,, and creator of SchubinCafe.com, has published a 4K TV primer for broadcasters, TV production people, journalists covering the TV industry, and TV viewers.

The primer, Y4K?, looks at 4K as the future of television.

What should come after HDTV? There’s certainly a lot of buzz about 3D TV. Such directors as James Cameron and Douglas Trumbull are pushing for higher frame rates. Several manufacturers have introduced TVs with a 21:9 (“CinemaScope”) aspect ratio instead of HDTV’s 16:9. Some think we should increase dynamic range (the range from dark to light). Some think it should be a greater range of colors. Japan’s Super Hi-Vision offers 22.2-channel surround sound. And then there’s 4K.

In simple terms, 4K has approximately twice as much detail as HDTV in both the horizontal and vertical directions. It’s called 4K because there are 4096 picture elements (pixels) per line.
