Technical adequacy is a prerequisite. The technically best solution is not a prerequisite. In case it isn't obvious yet, an open, adequate format is preferred over a better proprietary one. > If you consider mobile devices that want to browse the Web, then > depending on the constraints of the device, a hardware solution may be > required to view video with any kind of reasonable performance.

Thanks. I wasn't previously convinced we needed to mandate *any* particular format, but you just convinced me. If hardware is support is required for some devices, then it does indeed sound like a good idea to mandate some minimum level of conformance. It is far better that this minimum level of conformance be an open, freely implementable standard such as Ogg/Theora than a known patent encumbered format such as H.264. > Or put another way, imagine that GIF was an open format but PNG was > IP-encumbered. Would you really want to limit the Web to displaying > only GIFs just because it was the only open image format available? Please stop attacking straw men. No one has suggested that. Under those circumstances, I absolutely would support requiring all browsers to display GIFs. This would not prohibit them from also displaying PNGs if they chose to license the relevant patents. > Technical arguments are relevant here, so take some time to consider > them before accusing people of having shady ulterior motives. Technical arguments are relevant, but do not control. They are neither the only nor the most important consideration. Furthermore, when apparently intelligent people persist in making simple logical and rhetorical errors, it is difficult not to infer that an ulterior motive may be present. -- Elliotte Rusty Harold elharo at metalab.unc.edu Java I/O 2nd Edition Just Published! http://www.cafeaulait.org/books/javaio2/ http://www.amazon.com/exec/obidos/ISBN=0596527500/ref=nosim/cafeaulaitA/
