Unlike audio CDs, DVDs are already compressed digital data. We're going to start tossing these things around like candy. A few of the video sharing websites offer something perilously close to DVD quality already. Today, those specs are rapidly becoming pedestrian in the face of high definition cable, broadcast, and Blu-Ray discs. Dolby Digital (AC-3) or Digital Theater System (DTS) digital multichannel sound.720 x 480 MPEG-2 video at 30 frames per second.At the time, they were a technical marvel: I bought my first DVD about 10 years ago.
And one of my very favorite tasks in that niche is encoding your DVD collection. Maybe the word I want is "bubble.")ĭespite that, I've acknowledged all along there are certain narrow tasks that the proliferation of CPU cores will make dramatically faster. (No - that's the wrong metaphor! "Pipelines" actually work for me, but threads don't. So why should I be so happy about the future that hardware vendors promise? They think a magic bullet will come along to make multicores speed up my kind of work I think it's a pipe dream. If I had four processors, or eight, or more, I still wouldn't be any better off, considering the kind of work I do - even though I'm using my computer almost every day during most of the day. I get to use them both only when I'm running two independent jobs at the same time that's nice, but it happens only a few minutes every week. The machine I use today has dual processors.
Like Donald Knuth, I think much of the current multicore hype is overrated.
