What does “CVD” mean?

Posted on September 12, 2017. Filed under: Definitions | Tags: , |

Let’s quote the 2003 NFO of the episode using the tag:

CVD?? What is it?

CVD is a DVD legal format. It can be burned to CDR
and played on standalone DVD players and it can be
used in any DVD authoring application and burned to
a DVD -/+ r.

What does this mean to you?

It means you can extract the mpeg2 form the bin/cue
and combine it with future episodes without having
to re-encode or use cDVD format

What is CVD exactly?

Its a legal DVD format known as D1 1/2 its size
is 352 x 480 and while this seems less then SVCD
it actually is higher quality and supports much
higher bitrates, SVCD is made to be compatible
CVD not the reverse.

CVD was developed by C-Cube Microsystems and its
Chinese OEM partners, blah, blah, blah…

Taken from vcdhelp:

– If you are a quality freak, then the CVD format is
a better choice than SVCD. CVDs can use the same
bitrates as SVCDs but for a lower Horizontal resolution.
So, the data shared to each field/frame is more for CVD,
than the data shared to each field/frame for SVCD. That
is the secret: More data per frame, at the same bitrate,
better picture for CVD.

https://en.wikipedia.org/wiki/China_Video_Disc

China Video Disc (CVD) is a CD-based video format which was created during the development of the SVCD standard and is almost identical to SVCD. The primary technical difference is a lower (horizontal) video resolution of 352×480 (NTSC) or 352×576 (PAL/SECAM). Because 352×480/576 is a recognized DVD resolution, CVD video (but not audio) is fully compatible with the DVD-Video standard, and avoids the “foldover” (or aliasing) problems encountered when playing SVCDs on DVD players. The lower resolution also allows the bitrate to be reduced while keeping compression artifacts to a minimum. CVD also supports all of the additional features (selectable subtitles, multiple audio tracks, and so on) which are supported by SVCD.

SVCD players are required to be fully compatible with the CVD standard. However, “SVCD compatible” DVD players sold in North America have no such requirement, and may not be able to play CVDs, or utilize the interactive menus and subtitles found on some CVDs and SVCDs.
