SVCDs store digital video in MPEG-2 format at a resolution of 480x480 pixels (for NTSC) or 480x576 pixels (for PAL). There is no standard for a SECAM-format SVCD.
Video may be encoded at a variable bit rate, up to 2.6 megabits per second. Audio is stored in MPEG Layer 2 format, with a bit rate varying from 128 to 384 kilobits per second. With ordinary recordable CD-R media, approximately 35 to 60 minutes of video and audio can be stored.
The SVCD format has a number of advantages over VCD in addition to increased picture quality. SVCD discs can theoretically have up to 8 channels of audio (in a 7.1 arrangement) via the MPEG Multichannel surround sound format. However, most discs have only standard MPEG stereo (2.0), bilingual (1+1) or mono (1.0) channel audio, probably because of the lack of MPEG Multichannel-compliant hardware (especially in NTSC countries) and the space-constraints of CD-ROM media.
(Note that Dolby DigitalDescription Dolby Digital is the trademark for Dolby Laboratories' AC-3 lossy audio compression (or data reduction) system. It is a system for coding and decoding ( codec) digital audio sound so that it occupies less space on the recording medium. It is t, DTSIn cinemas, DTS Digital Theater Systems is a multichannel audio source for synchronized film sound. A modified time code is optically imaged on the film itself, and the DTS processor uses this to synchronize the soundtrack audio which is recorded in a com and other surround sound formats are not used or supported with SVCD - only MPEG Multichannel. This may be because MPEG Multichannel was developed by PhilipsCompany logo Koninklijke Philips Electronics N. Royal Philips Electronics), usually known as Philips is one of the largest consumer electronics producers in the world. In 2003, their sales were €29. 0 billion and they employed 164,000 people in more, who also co-developed the SVCD format, and is a competitor of other digital audio formats.)
Additionally, it has support for overlay subtitleIn printed material In printed material, a subtitle is an explanatory or alternate title. For example, Mary Shelley used a subtitle to give her most famous novel, Frankenstein; or, the Modern Prometheus an alternate title to give a hint of the theme.s and karaokeKaraoke ( in Japanese) is a form of entertainment where an amateur singer accompanies recorded music. The music is of a well-known song in which the voice of the original singer is absent or reduced in volume. Lyrics are usually also displayed, sometimes lyric highlighting, hyperlinkA hyperlink or simply a link is a reference in a hypertext document to another document or other resource. As such it would be similar to a citation in literature. However, combined with a data network and suitable access protocol, it can be used to fetchs, and still-image slide shows with resolution up to 704x480 (NTSC) or 704x576 (PAL), very similar to DVD.
SVCD resolution is slightly lower than LaserdiscLaserdisc was the first optical disc storage medium, and was used primarily for the presentation of movies. During its development, the format was referred to as the "Optical Videodisc System" before MCA, who owned the patent on the technology, re-named t's effective resolution of 567x480, though Laserdisc uses an analog signal which causes some quality degradation, so the two formats are roughly comparable in picture quality. A well-encoded SVCD has a picture quality far better than VHSThe Video Home System better known by its acronym VHS is the recording and playing standard for video cassette recorders (VCRs), developed by JVC and launched in 1976. It became a standard format for consumer recording and viewing in the 1980s after compe. Most casual users cannot tell the difference between a good SVCD and a DVD.
