DVCD format

greenspun.com : LUSENET : Video CD : One Thread

There is a new format in the market called DVCD. It is basically a two-in-one VCD disk. Movies that was split onto 2 VCD disks were combined onto a single disk. It is compatible with current VCD player and CD-ROM. Anybody knows how they achieved this feat? Thanks.

I don't own any, but I have friends who do. I suspect that they use Variable Bit Rate (VBR) coding rather than the standard Constant Bit Rate (CBR) coding in the White Book Standard. MPeg-1 doesn't define the bit rate so any generic Mpeg-1 decode chips would render it without caring. Don't know about really old VCD player though. None of my friends had problems, but they all stay on the bleeding edge.

Another possibility would be more "b" frames and better prediction but I can't see how that would win you more than 20-30% extra time.
