The steady progression of compressed digital audio into all sorts of places (do you really need to listen to Mozart on a PDA?) is raising all sorts of issues. But none is more important to readers of Sound & Vision than the ability of the codecs - the encode/decode software - to faithfully reproduce music after compressing CD tracks to file sizes that can be easily downloaded or stored.

Okay, I know I shouldn't gloat. But I told you so. In a keynote speech at the National Association of Broadcasters (NAB) annual convention a year ago, I warned that if the broadcast and cable industries didn't get their act together when it came to putting high-definition signals out there in a big way, high-def programming would be provided by other means.

The players are in position, and the pieces are now on the board. But this is not a chess game, and the stakes are even higher than in the richest of Grand Master tournaments. This is the beginning of another video-recorder format war, but unlike the VHS vs. Beta conflict of the late 1970s and early '80s, there are three competing formats.
