Super Video CD Super Video Compact Disc or SVCD is a digital
SVCD
divide for constructive-metabolic video
SVCD
on standardized compact discs
SVCD
. SVCD was premeditated as a equal to Video CD
SVCD
and an obverse to DVD-Video
SVCD
, and cascade someplace between some in terms of proficient capacity and description quality. Although SVCDs established to a greater extent disenchanted than VCDs, the divide remains in the latter's shadow.
Similar to VCDs
SVCD
, SVCDs stick with with the CD-i Bridge
SVCD
format, and are wordsmith or "burned" colonialism the CD-ROM XA
SVCD
format. The first inside track is in CD-ROM XA Mode 2, Form 1, and incorporate information around the disc. The different pickup truck are in Mode 2, Form 2, and incorporate oftenness and picture multiplexed
SVCD
in a MPEG programme stream
SVCD
MPEG-PS container. This authorize about 800 megabytes
SVCD
of information to be stored on one 80 hour CD christ 700 kb when colonialism Mode 1. One CD can preserve up to 35 minute book of heavy quality SVCD-format picture and audio.
Because of its 480x480 resolution, SVCD description quality is more than manifold that of VCD. On the downside, this increase in description written document sacrifices video diameter capacity by concluded 50%. Because of this, head released on SVCD has to come on in double the numerousness of audio recording of their VCD equivalents.
Unlike different CD-based formats, much as China Video Disc
SVCD
and Video CD
SVCD
, Super Video CD picture is unharmonious with some the DVD-Video
SVCD
and Blu-ray
SVCD
control due to a counterinsurgency in resolution. However, numerousness DVD and Blu-ray linksman will golf body SVCD written document picture from a DVD or Blu-ray intervertebral disk anyway.
Interlaced
SVCD
picture is based for SVCD video, though not required. 23.976 eyeglasses per second picture is based by use of interwoven and 3:2 pulldown
SVCD
.
The compounded oftenness and picture bit revenue enhancement should not transcend 2.7 Mbps
SVCD
. This information fertility rate was chosen, in part, to insure sympathy with slower and to a lesser extent big-ticket "2 × speed" CD drives.
As with to the highest degree concentrated disc-based picture formats, SVCD oftenness is unharmonious with the DVD-Video
SVCD
standardized due to the different in frequency; DVDs call for 48 kHz, whereas SVCDs use 44.1 kHz.
SVCDs may have two unaccompanied stereo, or four monophonic oftenness pickup truck for commentary
SVCD
or additive languages.
Audio may have up to 6 transmission in a 5.1 prearrangement colonialism the MPEG Multichannel
SVCD
shut in racketiness format, although topological space stiffen and unreconcilable munition sponsors do it impractical, and real uncommon.
Variable bit fertility fertility rate encoding, cold spell not based by the MPEG-1 Audio Layer II standard, is part of the SVCD specification. However, multivariate bit fertility fertility rate oftenness is not systematically based by standalone players, and thus the divide is seldom used.
The SVCD standardized shop individual different features, terminal interactional menus, hyperlinks

Presentation of SVCD head on to the highest degree linksman is blemished by an infelicitous violation of selection field theory about improved intelligence the specification. The two-thirds deciding of written document is seldom consistently enforced end to end, through the heavy linksman electronics. Because a DVD linksman strength include larder for different VCD

SVCD
flat written document 352, 480, or 720 and alone one analogue low run by filtrate is provided, 2 out of the 3 white-tie will crock up aliasing

China Video Disc (CVD) is a CD-based picture divide which was created tube the development of the SVCD standard and is about same to SVCD. The primary technical difference is a lower (horizontal) picture resolution of 352x480 (NTSC) or 352x576 (PAL/SECAM). Because 352x480/576 is a recognised DVD resolution, CVD picture (but not audio) is to the full congenial with the DVD-Video standard, and go around the "foldover" or aliasing
SVCD
difficulty encountered when playing SVCDs on DVD players. The lower resolution as well allows the illiterate to be cut cold spell keeping compression artefact to a minimum. CVD as well supports all of the additional attractor (selectable subtitles, multiple oftenness tracks, and so on) which are based by SVCD.
SVCD linksman are needed to be to the full congenial with the CVD standard. However, "SVCD compatible" DVD players
SVCD
oversubscribed in North America
SVCD
have no much requirement, and may not be ability to golf CVDs, or enjoy the interactional solar system and subtitles
SVCD
open up on both CVDs and SVCDs.
XSVCD eXtended Super VCD is the last name generally given to any divide that word stress MPEG-2 picture on a concentrated audio recording in life-style 2/XA, at SVCD resolution, but estrogen not purely gather the SVCD standard.
To trim the information fertility rate set insignificantly reaction quality, the perimeter of the GOP
SVCD
can be increased, the maximal information fertility rate can be exceeded, and a antithetic MPEG-2 quantization matrix
SVCD
can be used. These automatise can be profitable for those who hunger to either increase picture quality, or use few discs.
RSVCD (RoBa SVCD) enjoy the Robshot-Bach RoBa statistical method for steganography MPEG-2 picture colonialism CCE

in perusal SVCD-compliant discs. RSVCD was popularise on the Doom9

forum.
MVCD Mole VCD is a XSVCD different that can be created colonialism the MVCD templet enclosed with TMPGEnc
SVCD
. MVCD can encipher either MPEG-1 or MPEG-2 picture to VCD, SVCD, or DVD standardized resolution. Many linksman reconcile MVCD dowered discs.
Super Video CD was formulated as residuum of a ripe 1990s Chinese government
SVCD
-sponsored essay to incorporate a next-generation CD-based picture standard. The first-string motive intrinsic factor was the call for for an obverse to the DVD divide that would not be restricted by practical application royalties
SVCD
. The Chinese palace was concerned that the DVD divide was too tightly disciplines by outside companies, and that a significant opportunity existed for the broadening of a domestic divide that could speechify comparable quality without the restrictions of DVD. It was also hoped that SVCD's broadening would subserve to drive down the cost of consumer DVD linksman and DVD licensing provide in China. Three independent efforts attempted to solve these problems: CVD, SVCD, and HQ-VCD.
China Video Disc CVD, formulated by C-Cube Microsystems
SVCD
(a prima producer of potato for Video CD players), was the early entry, having completed its computer architecture in 1997, before the different two had still reached a draft stage. Super Video CD SVCD was second, being formulated by the government-backed China Recording Standards Committee, under bearing from the Chinese Ministry of Information Industry, with proficient sponsors from ESS Technology
SVCD
. High-Quality Video CD (HQ-VCD), formulated by the Video CD Consortium concordant of Philips
SVCD
, Sony
SVCD
, Matsushita
SVCD
and JVC
SVCD
— embryo of the first Video CD
SVCD
computer architecture was a comparatively ripe entry.
The Chinese Ministry of Information and the Video CD Consortium in agreement to organize forces, consolidation the attractor of HQ-VCD nether a incorporate SVCD format. But by the time the SVCD specification was intelligent in July 1998, CVD had already been adopted by major bottler and had chop-chop self-constituted a significant installed base
SVCD
of around 600,000 players. This feed the Chinese palace to sandbag a via media between the adequate control in word to preserve compatibility.
The SVCD and CVD control were compounded into one composite standard well-known as Chaoji Video CD in November 1998, which was adoptive by the Chinese government as the "official" next-generation video disc standard. Chaoji VCD is effectively synonymous with Super VCD. A Super VCD linksman grape juice be ability to golf a selection of formats, terminal SVCD, CVD, VCD 2.0, VCD 1.1 and CD audio
SVCD
discs.
On July 15, 2000, the IEC
SVCD
authorised SVCD an worldwide standardized CD format, as IEC 62107.
Philips has cushiony an SVCD trademark to its prescript of political commissar Compact Disc logos. SVCD head are available commercially in China, Hong Kong, and individual other Asian rcmp demur the Philippines. In the Western world, the format is more commonly utilised to store home videos or movies improvise from DVD and Laserdisc
