INTRODUCTION
There is a market need for a standardized fully digital Compact Disc based video reproduction
system. This Super Video CD specification standardizes and upgrades the current Video CD
format. It utilizes better Video and Audio quality. It also includes extensions for surround
sound multi-channel audio and provisions for PC playback, and is prepared for further future
improvements. This standard is based on using variable bit rate (VBR) MPEG2 coding for
more efficient use of disc capacity. The target for this standard is further to ensure the best
price/performance combination possible with the latest state-of-the-art technology available,
and to offer more flexibility for publishers to use the best video/audio quality given limited disc
capacity.
Attention is drawn to the possibility that some of the elements of this International Standard
may be the subject of patent rights. Recipients of this standard are invited to submit, with their
comments, notification of any relevant patent rights of which they are aware and to provide
supporting documentation.

The most significant bit is the bit with the highest bit position number.
Figure 1 – Example of bit ordering for one 8-bit byte

62107 © IEC:2000(E) – 9 –
Byte ordering – Quantities which require more than eight bits for their representation are
held in more than one byte on the disc. For all such quantities, the ordering of bytes on the
disc (as seen at the interface to the disc driver) is such that the Most Significant Byte (MSB)
is first and the Least Significant Byte (LSB) is last.
Multiple-byte quantities are represented graphically such that the left-most or upper-most byte
is most significant and the right-most or lower-most byte is least significant.
__ MSB __ __ LSB __
‰ �‰ �
b15 . b8 b7 . b0
__ byte Bn __ __ byte Bn+1 __
‰ �‰ �
IEC  1013/2000
The most significant byte is the byte with the lowest byte position number.
Figure 2 – Example of byte ordering for 2 bytes
Character String – Character Strings are always given between double quotation marks, as
"_____", coded according to ISO 646 if not indicated otherwise.
Hex – All hexadecimal values are preceded by a $. The most significant nibble is on the left,
the least significant nibble is on the right.
Binary – Binary values are preceded by a % or presented within single quotation marks ' '.
The most significant bit is on the left, the least significant bit is on the right. A binary value is
represented by a 0, 1 or x where x is a 0 or a 1.
Decimal – All decimal values are preceded by a blank space or the range indicator (.) when
included in a range. The most significant digit is on the left, the least significant digit is on
the right.
Units of measure – 1 K denotes 1 024 units.
Range – Constant_1.Constant_2 or (Constant_1.Constant_2) denotes the range from and
including Constant_1 up to and including Constant_2, in increments of 1.
Ordering within tables – The items within a table are contiguous, starting with the top line
from the left to the right item, then the next line from the left to the right item, and so on, down
to and including the bottom line from the left to the right item.
3.4 Compatibility conventions
The SuperVCD specification is intended to ensure full compatibility, so that all discs can play,
with at least those functions designated as mandatory in the SuperVCD specifications, in all
compliant playback devices.
All mandatory parts of the specification have to be recorded on all discs and are intended to
be implemented in all playback devices.
Extension parts of the specification define non-mandatory additional functionality.
A disc with extensions should play on a playback device only supporting the mandatory
functionality of the specification, and a playback device supporting some or all extensions
should also play discs without these extensions.
The specification also includes optional meta-data, intended to support improved performance
of a playback device. It is recommended that optional items be recorded on the disc, but it is
not required that they be included.

4 SuperVCD introduction
4.1 System overview
SuperVCD is a reproduction system for presenting full motion pictures with associated audio
by using the Compact Disc format. The system uses the ISO/IEC MPEG2 standard definitions
to compress the video, still picture and audio information for full screen TV quality pictures
together with associated high-quality audio. The SuperVCD disc can also carry high-quality
still pictures with associated audio and a Play Sequence Descriptor file for interactive control
of the playback of still and motion pictures.
Variable bit rate (VBR) MPEG coding is used for more efficient use of the disc capacity. The
playing time for a fully recorded disc can vary from 35 min to more than 70 min depending on
the average bit rate used.
The SuperVCD format is based on the CD-ROM Mode 2 disc format. SuperVCD discs can be
played on SuperVCD playback devices, and other compliant hardware and software platforms.
4.2 SuperVCD system reference model
The SuperVCD system consists of a SuperVCD disc and the playback device, normally a
SuperVCD player.

5 General SuperVCD disc format
The general SuperVCD disc structure is based on the CD-ROM system (ISO/IEC 10149) with
the specific additions and restrictions defined in this clause.
The disc is intended to be played either sequentially starting from the first MPEG Track, or by
playing Play Lists using the Play Sequence Descriptor (PSD) with on-screen “menu” control.
A karaoke/music application has normally one track per song. This means that song number 1
is recorded in Track No. 2, and song number 2 in Track No. 3, and so on.

62107 © IEC:2000(E) – 11 –
A movie title can be divided into different coded parts, such as INTRO, COPYRIGHT, FILM,
CREDITS. The film itself can also be subdivided into chapters.
5.1 SuperVCD disc structure
The SuperVCD disc has a lead-in area, a program area, and a lead-out area.
Lead-in area
Track No. 1 SuperVCD DATA track

Track No. n
Lead-out area
IEC  1015/2000
Figure 4 – SuperVCD disc layout
5.1.1 Lead-in area
The lead-in area is encoded as a CD-ROM DATA track (with track number = 00) containing
Empty Sectors of Mode 2 Form 2 with file number = $00, and Submode = $20.
Table 1 – Lead-in area subcode
POINT $A0
PSEC $20
PFRAME $00
5.1.2 Program area
There are two types of SuperVCD track format:
– SuperVCD DATA track format
– SuperVCD MPEG track format
The first track shall be a SuperVCD DATA track and other tracks shall be SuperVCD MPEG
tracks with playable MPEG2 audio/video Program Streams.
All sectors in a SuperVCD track are of CD-ROM Mode 2.
5.1.3 Lead-out area
The lead-out area is encoded as a CD-ROM DATA track containing Empty Sectors of Mode 2
Form 2 with file number = $00, and Submode = $20.
5.2 SuperVCD sector format
A track is divided into Mode 2 sectors of 2 352 sequential bytes each. Each sector can be
uniquely addressed by a BCD-coded absolute time value in the header field of the sector.
SuperVCD information is stored in SuperVCD sectors.
There are two types of SuperVCD sectors, namely Form 1 and Form 2 sectors. A Form 1
sector has an extra Error Correction Code (ECC) field, as in CD-ROM Mode 1. A Form 2
sector is intended for real time MPEG data and has no ECC field, but 2 324 user data bytes
instead, giving a 14 % higher bit rate or capacity.

The Subheader is used to define different types of sectors for storing information with special
characteristics. The values are defined in table 5.
Depending on the SuperVCD information, three types of sectors are defined, namely an
Empty sector with no user data information, a Data sector with non-real-time data and an
MPEG sector for MPEG real-time data.
The Submode byte defines the global attributes of a sector, and the Coding Information byte
defines if the sector contains MPEG PS stream data.

– The EDC shall be calculated from the beginning of the Subheader field to the end of
the 2 048 byte User Data field.
– Parity P of the ECC shall be calculated from the beginning of the Header field to the end
of the EDC field as if the content of the Header field were all zero.
– Parity Q of the ECC shall be calculated from the beginning of the Header field to the end
of the EDC field as if the content of the Header field were all zero.
5.2.3 Form 2 SuperVCD sector EDC field
The EDC field is defined as for CD-ROM Mode 1 with the following exception.
– The EDC shall be calculated from the beginning of the Subheader field to the end of
the 2 324 byte User Data field.
5.3 SuperVCD DATA track format
This shall be the first track of the disc.
The DATA TRACK starts with a pre-gap of 150 Empty sectors.

intended for interactive playback under control of the Play Sequence Descriptor.
Segment Play Items are not accessed directly by the normal track playing mechanism, but
indirectly by interpretation of the Play Sequence Descriptor (PSD).
The SPI is stored into contiguous segments of 150 sectors in length and is addressed by a
segment number. The length of the SPI Area shall be any integer number of segments
ranging from 1 to a maximum of 1 980. The segments are numbered consecutively starting
from No. 1, which is the first segment.
The start sector address of the SPI Area is indicated in the First Segment Address entry of
"INFO.SVD".
62107 © IEC:2000(E) – 15 –
Segment Play Items shall conform to Program Stream coding as described in the Program
Stream format Section.
Segment Play Items may occupy one or more segments, and the data shall start at a segment
boundary. The SPI data is padded with Empty Sectors to the end of a whole segment. An
SPI is identified by its SPI number, which is equal to the number of its first segment. Only
segment numbers that correspond to the first segments of Segment Play Items and are in the
range 1.1980 are valid SPI numbers. The figure below gives an example of the Segment Play
Items in the SPI Area.

5.3.3 Other files
Other SuperVCD files are stored in the EXT directory.
5.4 SuperVCD MPEG track format
The SuperVCD disc shall contain at least one MPEG track. Each MPEG track is identified by
a sequence number starting from 01 which is incremented for each following MPEG track, so
that the MPEG track with track number 02 has the sequence number of 01.
In general these tracks are intended for linear playback in sequential order.
Each MPEG track shall contain only one MPEG2 Program Stream, stored in MPEG sectors.
The Program Stream coding is described in clause 7. The Program Stream shall contain
Motion Video. (Audio-only tracks are not allowed.)
An MPEG track starts with a Pause encoding of minimum 150 Empty sectors. Thus a movie,
which needs to be played back seamlessly, shall be recorded in one track.
An MPEG Track can be subdivided into parts or chapters (see the ENTRIES.SVD file
description in 6.3.2).

6 Data Retrieval and File system structure
The SuperVCD disc contains a data retrieval structure with a File System structure that
conforms to ISO 9660, and the DATA track shall contain a Primary Volume Descriptor (PVD).
Next to this some files in the DATA track have fixed start addresses.
6.1 ISO 9660 Volume structure
The disc has only one Volume.
6.1.1 ISO 9660 Primary Volume Descriptor (PVD)
Sector No.16 contains the PVD for the disc and is located at the absolute address
of 00:02:16.
The PVD Volume Set Size field (BP 121 - 124) and the Volume Sequence Number shall be set to 1.
6.1.2 PVD Disc Label
SuperVCD discs require the presence of an identical Disc Label in all copies of the PVD. The
Disc Label is located at offset 1024 of the PVD (byte position 1025).
Table 7 – SuperVCD Disc Label
Byte position Field name Content Note
1025 – 1032 ID signature “CD-XA001” Character coded
1033 – 1050 reserved all zero bytes $00 bytes
6.1.3 Path Table
The ISO 9660 Path table is stored in SuperVCD DATA sectors. The ISO 9660 defined version
number of all files shall be "1", but in this document the version numbers are not shown.
6.1.4 Directory record
Directory records are stored in SuperVCD DATA sectors.
In the Directory Record the file flags (BP 26) of Record bit, Associated File bit,
Protection bit and Multi-Extent bit shall be set to %0. There shall not be more than one
version of a file.
All SuperVCD defined files shall include additional system use information in the Directory
as follows:

62107 © IEC:2000(E) – 17 –
6.2 Directory structure
The SuperVCD information files (see 6.3) shall be located in the directory "SVCD".
All files that represent the MPEG audio/video tracks shall be located in the directory
"MPEG2".
If the SPI Area is available on a disc then the "ITEMnnn" files shall be located in the directory
"SEGMENT".
The "SCANDATA.DAT" and "CAPTnn.DAT" files are located in the "EXT" directory.
Additional non-SuperVCD specified files or directories may exist outside the mandatory
SuperVCD directory hierarchy. Figure 8 gives an example of the file structure for a SuperVCD
disc.

Figure 8 – Example of the directory structure
6.2.1 Root directory
This is the Root directory of the disc. It contains directories and files as shown in figure 8.
6.3 SVCD directory
This directory contains all the SuperVCD Information files. Mandatory files are "INFO.SVD",
"ENTRIES.SVD", and "TRACKS.SVD". The file "SEARCH.DAT" is mandatory depending on
the System profile Tag.
It is recommended that all these files be recorded consecutively so a playback device can
read all the files with one seek access, which will improve the start-up performance of the
disc.
If the Play Sequence Descriptor (PSD) is present, then the SVCD directory shall also include
the files "LOT.SVD" and "PSD.SVD".

– 18 – 62107 © IEC:2000(E)
6.3.1 INFO.SVD file
The mandatory file "INFO.SVD" contains the SuperVCD system identification and a provision
for identifying the discs belonging to one album. An album is a series of discs which contain
related Audio/Video programs. The INFO.SVD file also contains information associated with
the Play Sequence Descriptor.
The "INFO.SVD" file is located at Sector 00:04:00 and has a fixed size of one sector.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (CEI) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a
pour objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les
domaines de l'électricité et de l'électronique. A cet effet, la CEI – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de la CEI"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec la CEI, participent
également aux travaux. La CEI collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de la CEI
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de la CEI se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de la CEI. Tous les efforts raisonnables sont entrepris afin que la CEI
s'assure de l'exactitude du contenu technique de ses publications; la CEI ne peut pas être tenue responsable
de l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de la CEI s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de la CEI dans leurs publications
nationales et régionales. Toutes divergences entre toutes Publications de la CEI et toutes publications
nationales ou régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) La CEI n’a prévu aucune procédure de marquage valant indication d’approbation et n'engage pas sa
responsabilité pour les équipements déclarés conformes à une de ses Publications.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à la CEI, à ses administrateurs, employés, auxiliaires ou
mandataires, y compris ses experts particuliers et les membres de ses comités d'études et des Comités
nationaux de la CEI, pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre
dommage de quelque nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais
de justice) et les dépenses découlant de la publication ou de l'utilisation de cette Publication de la CEI ou de
toute autre Publication de la CEI, ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L’attention est attirée sur le fait que certains des éléments de la présente Publication de la CEI peuvent fair
