The present invention relates to a multimedia storage medium, an optical disc on which the storage medium is recorded, and a player system capable of executing the same, wherein the multimedia content compressed in a predetermined format and a decoder, an application program, and an operating system for the execution thereof are encrypted in a predetermined language. The present invention relates to a storage medium, and an optical disc having recorded the same, and a player system for displaying multimedia contents of the optical disc to the outside.

Recently, thanks to the rapid development of the Internet and information and communication technology, multimedia digitization which converts various audiovisual data of voice and video into digital is rapidly progressing throughout the society. Moreover, such digital digitization enables many people to enjoy various multimedia data through the development of band compression technology and the expansion of wired and wireless communication networks such as the Internet.

Recently, as an example of a storage medium in which audio and video contents (hereinafter referred to as A / V contents) are recorded among these multimedia contents, a so-called 'Digital Versatile Disk' called 'Dream Media' has been introduced. -2 Standard A / V content is compressed and can be run on a computer equipped with a DVD player or DVD-ROM.

At this time, the DVD player has a built-in separate application package that can decode and execute MPEG-1 or MPEG-2 formats recorded on DVDs and compatible CDs (Compact Disk) and VCD (Video Compact Disk). Output port such as video terminal, S-video video terminal, component terminal, etc. is provided to display audio and video through TV and speaker.

In the case of a computer equipped with a DVD-ROM, the A / V content of the DVD is displayed to the outside through a predetermined operating system, a decoder, and a video player stored in a hard disk drive (HDD). If you insert a DVD and a compatible CD or VCD into a DVD-ROM, you can plug and play it into the operating system by the BIOS, and MPEG-1 or MPEG-2 by the decoder and the operating system. The format and A / V content are decompressed and converted to produce an A / V data stream.

The A / V data is externally displayed through computer monitors and speakers such as cathode-ray tubes (CRTs) or liquid display devices (LCDs).

In this case, the decoder is usually provided to the user as a separate software along with the DVD-ROM, which can be installed and used in a hard disk drive of the computer. The video player is also provided as a separate software and can be installed and executed on the operating system. . For reference, in order to execute such a DVD, a north bridge or a MCH and a south bridge or an ICH may be included to adjust a processing speed between a plurality of components communicated with each other in a computer.

On the other hand, in recent years, A / V content is not only MPEG-1 or MPEG-2, but also MPEG-4 (including MPEG-3, which is the same below), MPEG-7, and DivX (which are different from the rental system. .), Windows Media Audio / Video (WMA / WMV), Advanced Audio Coding (AAC) formats, etc. A DVD player with a dedicated decoder must be purchased or a decoder and video player for that format must be built in the hard disk drive of the computer.

In this case, although the computer is online, it is limited, but a decoder of a corresponding format provided by a specific ISP (Internet Service Provider) can be downloaded and executed. However, if the computer is offline, there is virtually no method of execution other than the purchase and installation of a decoder and a playback program. Since a hard disk driver of a high-powered computer is required, power consumption is disadvantageous.

The present invention has been made to solve the above problems, and provides a storage medium capable of executing all kinds of multimedia content irrespective of the computer's on / offline state and compressed format, and an optical disc on which the storage medium is recorded. .

In addition, another object of the present invention is to provide a player system capable of executing the above optical disk without a separate dedicated application package or a hard disk driver, unlike a computer equipped with a conventional DVD player or DVD-ROM . Furthermore, the present invention is intended to provide a variety of applications of the storage media, optical disks, and player systems that can execute them, thereby providing convenience in using multimedia contents.
