example 1

[0061] FIG. 1 shows the data structure of a system stream 210 according to the MPEG format. The optical disc includes at least one system stream 210 stored thereon.

[0062] System data stream 210 may include multiple elementary data streams. Elementary streams are classified into video elementary streams for storing motion graphics information and audio elementary streams for storing audio information. Each of the multiple elementary data streams is divided into multiple data packets. Each of the plurality of data packets has a length of 2K bytes.

[0063] In the example shown in FIG. 1, the system stream 210 is formed by an audio elementary stream. The system data stream 210 includes a plurality of audio data packets 220 . The plurality of audio data packets 220 are denoted by reference numerals A1-A14, respectively.

[0064] Each of the plurality of audio data packets 220 includes a packet header 222 , a packet header 224 and a data field 226 .

[0065] In the packet ...

example 2

[0121] A multimedia information storage medium according to a second example of the present invention will be described below.

[0122] (1) The physical structure of the disc

[0123] Figure 6A shows the appearance of DVD 107, which is a multimedia disc. Figure 6B shows a cross-sectional view of DVD 107 along line A-A' in Figure 6A. Fig. 6C shows an enlarged cross-sectional view of part B in Fig. 6B.

[0124] As shown in FIG. 6B, DVD 107 is formed by sequentially stacking first transparent substrate 108, information layer 109, adhesive layer 110, second transparent substrate 111 and printing layer 112, wherein a label will be printed in this order on printing layer 112.

[0125] The first transparent substrate 108 and the second transparent substrate 111 are reinforcing substrates formed of the same material. In the example shown in FIG. 6B, these substrates each have a thickness of about 0.6 mm. Each of these substrates may have a thickness in the range of approximately 0...

Abstract

An information storing disk including at least one system stream stored thereon. The at least one system stream includes a silent cell for defining a silent period and an audio cell for defining audio data to be reproduced after the silent period. The silent period is a period to be silent, which is from when one system stream to be reproduced among at least one system stream is determined until reproduction of an audio cell included in the one system stream is started.

Description

technical field [0001] The present invention relates to an information storage disc for storing a system data stream, and a device and method for reproducing the system data stream from the information storage disc. In particular, the present invention relates to an information storage disc for allowing a plurality of reproducing devices having different performance levels such as data processing speeds to have the same waiting time before starting reproduction of a system stream, and to an Apparatus and method for reproducing the system data stream from the information storage disc. Background technique [0002] Conventionally known optical discs for storing information to be reproduced and motion picture information include compact discs (CDs) and laser discs (LDs). [0003] A CD is an optical disk having a diameter of 12 cm and stores digital data obtained by encoding music information using an encoding technique called linear PCM (Pulse Code Modulation). CDs have been ...
