Okay. Semis are up across the board. But the Cubic Hair is down on robust volume. What gives - anyone out there know something?

Video compression. Sony vs. the rest...........................

The Great Compression Debate, Part 2:
It's Sony vs. The Rest
By Ken Jones

At NAB 98 there was only one issue that mattered to Europeans: Sony versus The Rest. In theory it's the struggle between digital compression systems. In practice it's a raw commercial competition where there's no room for compromise. Either the broadcast television world adopts Studio Profile MPEG-2 (Sony's SX format) or it doesn't. If it does, all other manufacturers sub-license Sony designs and patents. If it doesn't, in all probability Sony departs the broadcast world.

So what, you ask -- it's just be a re-run of Betacam versus MII, right? Wrong. Ten years ago Sony and Panasonic came up with rival analogue tape systems which offered an order of magnitude improvement in portability and quality. There was little to choose between them, and the issue became one of penetration -- whichever standard became dominant would wipe out its rival.

This time there's a fundamental technical difference between the two 'camps.' Sony's compression system gives lower data rates, and hence cheaper storage and faster data transfers, but at the expense of flexibility. Panasonic (leaders of 'the Rest') have adopted a flexible compression system which needs higher data rates for a given quality level and is therefore more expensive byte-for-byte.
