With the advent of high-definition television (HDTV), MPEG-2 content will become a worldwide, mainstream video format. For that reason, the related decoding issues will remain important. Hardware decoders are coming down in price while they are going up in functionality. New designs are showing up that do an excellent job of integrating 2-D and 3-D parts.

Pure software decoding might be achieved on 300-MHz or 400-MHz PCs, with some 266-MHz systems doing a good job with some content now. The problem with pure software on 266-MHz and slower systems is that they don't leave enough processor room for interactive content, and they may not play all titles in the marketplace today.

The best software-based solutions combine hardware and software decoding. We are now seeing motion compensation and inverse discrete cosine transform (IDCT) acceleration in PCs that give the processor enough headroom to allow for some interactivity or use of the host or 3-D pipeline for other computing activities.

The 2X DVD-ROM drives that are shipping now are capable of 18 Mbps and cost just a few percent more than a high-end CD-ROM drive did just a year or two ago. Because DVD-ROM also reads CD-ROM, in the near future OEMs will spend their budget for spinning optical media on DVD-ROM drives, leaving little reason to ship CD-ROM.
