The China Video Disc (CVD), developed in the late 1990s, is a Chinese government-sponsored competitor to the SVCD standard. CVDs use variable bit-rate MPEG2 video encoded at 352x480 (NTSC) or 352x576 (PAL) rather than 480x480 (NTSC) or 480x576 (PAL) as with SVCDs. This lower resolution allows for video to be encoded at a lower bit-rate with less visual artifacts, which means longer videos are possible. CVDs are compatible with most DVD players sold in the United States. The 1990s decade refers to the years from 1990 to 1999, inclusive. ... This article is on the politics of Mainland China. ... Super Video Compact Disc (SVCD) is a format used for storing video on standard compact discs or CD-Rs. ... MP2, also known as Musicam, is a short form of MPEG-1 Audio Layer 2 (not MPEG-2), and it is also used as a file extension for files containing audio data of this type. ... NTSC is the analog television system in use in Korea, Japan, United States, Canada and certain other places, mostly in the Americas (see map). ... PAL, short for phase-alternating line, phase alternation by line or phase alternation line, is a colour encoding system used in broadcast television systems in large parts of the world. ...

Due to its encoding format and its resolution -- which is half of the resolution used on standard DVD-Video discs, but still supported by DVD-Video standards -- the format can be easily transferred from typical CDR storage to a DVDR. The main difference is that the format uses 44.1kHz MP2 audio, whereas PAL DVD-Video discs require 48kHz MP2 audio and NTSC DVD-Video discs don't support MP2 officially at all. DVD is an optical disc storage media format that is used for playback of movies with high video and sound quality and for storing data. ... MP2 can refer to: MP2 (format) audio files This is a disambiguation page, a list of pages that otherwise might share the same title. ...
Video is encoded as MPEG-2, and may have a variable bit rate up to 2.6 megabits per second.
CVD was first out of the gate, and had completed its specification before the other two had even reached a draft stage.
The Ministry of Information and Video CD Consortium agreed to join forces, incorporating the features of HQ-VCD under a unified SVCD format, but by the time their specification was ready in July 1998, CVD had already been adopted by major manufacturers of VCD players.
