IEC 62107:2000 pdf download.Super video compact disc – Disc-interchange system-specification
1 Scope
This International Standard defines the basic specification of the Super Video Compact Disc, (SuperVCD), characterized by high resolution and high picture quality, which matches current TV receivers. This standard is intended to be used as a basis for the design, production and compliance testing of SuperVCD discs and playback devices to achieve compatibility with current and future products. The general SuperVCD disc structure is based on the CD-ROM system (see ISO/IEC 1 01 49).

3 Definitions, abbreviations, conventions and symbols
3.1 Definitions
3.1 .1 bit rate
rate at which a compressed bit stream is delivered to the input of a decoder
3.1 .2 mnemonics
descriptions of different data types used in this standard
3.1 .3 mode 2 form 1
CD-ROM track type
3.1 .4 mode 2 form 2
CD-ROM track type
3.1 .5 mux rate
rate value derived from the sector rate
3.1 .6 playback device
any SuperVCD compliant player or other product, such as a PC
3.1 .7 program stream
a collection of elementary streams
3.1 .8 real-time stream
MPEG2 program stream containing video and audio components to be decoded and
presented in time, controlled by timing characteristics in the stream to the decoder
3.1 .9 system clock reference
time stamp in the Program Stream
3.1 .1 0 sector
smallest addressable part of a Digital Data Track in the information area that can be accessed
independently of other addressable parts of the area
[ISO/IEC 1 01 49]
3.1 .1 1 sector and subcode address representation
all Sector addresses and Subcode addresses are represented in the 3-byte BCD encoded
form mm:ss:ff. The minutes field is represented by “mm”, the seconds field is represented by
“ss”, the blocks (Sector) or frames (Subcode) field is represented by “ff”
3.1 .1 2 time-stamp
time of a specific action such as the arrival of a byte or the presentation of a picture
3.1 .1 3 track
continuous area on the disc with one and the same Track Number in the CD Subcode
3.1 .1 4 variable bit rate
variation in time of arrival of the bytes at the input of a decoder
3.3 Conventions and symbols
Text written in italics is informative. The mathematical operators used are similar to those used in the C programming language and the use of brackets – {} – in tables is in accordance with the pseudo-c syntax (see 2.2 and 2.3 of ISO/IEC 1 381 8-1 ). Unless otherwise indicated, in this document the conventions used are as follows. Bit ordering – The graphical representation of all multiple-bit quantities is such that the most significant bit (msb) is on the left and the least significant bit (lsb) is on the right.
