Between H.264 & 90% price drop, will Adobe’s new media servers mean more YouTubes? | Berlind’s Testbed | ZDNet.com:
"One of the issues Towes and I cover is the shift from delivering what has been traditionally thought of as low-def video on the Net (and on-demand) to hi-def. What is hi-def video on the Net? In the TV world, hi-def is thought of as being at least 720 lines of vertical resolution if not 1080. But on the Net, the definition of hi-def is the subject of some debate. In the the interview, Towes defines 480 lines of vertical resolution as being hi-def for the Net, a full 2x the lines of vertical resolution found in the 320x240 sized video windows that were once commonplace on the Net, but are now less so (YouTube video windows are approximately 480W x 362h). Just for grins, take a look at ABC’s self-described HD channel for streamed content. I’m not sure how they do it (well, it involves a plug-in), but they do it well and wouldn’t it be something if all Net-based video-on-demand involved as many bits and full-screen video without caching problems."
