Title: Multi-Media System

Description:
FIELD OF INVENTION 
     The present invention relates to a multi-media system and, more particularly, to a multi-media system for adding personal data to audio and video (“AV”) data so that the personal data can be shown as well as the AV data to avoid the illegal copying of the AV data. 
     BACKGROUND OF INVENTION 
     Computers are often connected to websites through the Internet so that multi-media data can be downloaded to the computers from the websites through the Internet. The multi-media data can be stored in and played by the computers. Alternatively, multi-media players can be connected to the computers so that the multi-media data can be stored in and played by the multi-media players. 
     Whatever formats they are in, the multi-media data only include AV data. Any user can play, store, record and/or transfer the multi-media data deliberately and often illegally. 
     Hence, websites encrypt multi-media data based on voiceprints or directly encrypt the multi-media data before they provide the multi-media data to users, thus preventing the users from illegally copying the multi-medial data. The encryption is however not strict and might be cracked. In that case, the multi-medial data could be illegally copied. 
     The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art. 
     SUMMARY OF INVENTION 
     It is the primary objective of the present invention to provide a multi-media system for avoiding illegal copying of audio and video data. 
     To achieve the foregoing objective, the multi-media system includes an audio and video data provider, a writing device and a player. The audio and video data provider provides audio and video data. The player provides personal data. The writing device receives the audio and video data and the personal data and adds the personal data to the audio and video data before transferring the audio and video data and the personal data to the player. The writing device includes a display module for showing a first sub-screen and a second sub-screen including an account zone and a time-and-address zone. 
     Other objectives, advantages and features of the present invention will become apparent from the following description referring to the attached drawings.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
     Referring to  FIG. 1 , a multi-media system includes an AV data provider  1 , a writing device  2  and a player  3  according to the preferred embodiment of the present invention. 
     The multi-media data provider  1  provides AV data  11 . The AV data  11  may be provided in MPEG files, AVI files, compressed files or motion-picture files. The AV data provider  1  may be a web server, a desktop computer or a laptop computer. 
     The writing device  2  is connected to the AV data provider  1 . The writing device  2  receives the AV data from the AV data provider  1  and adds personal data to the AV data. The writing device  2  may be a personal computer or a combination of a control unit with a storage unit. 
     The player  3  may be a desktop computer, a laptop computer or a combination of a cellular phone with a camera. The player  3  is connected to the writing device  2  so that the player  3  provides the personal data to the writing device  2  before the writing device  2  transfers the AV data  11  to the player  3 . 
     Referring to  FIG. 2 , the player  3  includes a display module  31 . The screen of the display module  31  is divided into a first sub-screen  32  and a second sub-screen  33 . The secondary sub-screen  33  includes an account zone  331 , a time-and-address zone  332 , a bonus zone  333  and a lottery zone  334 . 
     Referring to  FIG. 3 , the AV data provider  1 , the writing device  2  and the player  3  are in communication of data with one another wirelessly or through cables. The wireless communication of data between these elements may proceed according to the WiFi protocol, the Bluetooth protocol or the RF protocol. 
     Wishing to download the AV data  11  from the AV data provider  1 , a user connects the player  3  to the AV data provider  1  via the writing device  2 . The user provides the personal data to the writing device  2  before selecting the AV data  11  from the AV data provider  1 . The AV data provider  1  provides the AV data  11  to the writing device  2 . The writing device  2  adds the personal data to the AV data  11 . The personal data include data related to the user and data about the downloading of the AV data  11 . Then, the writing device  2  provides the player  3  with the AV data  11  added with the personal data. 
     Based on the AV data  11 , the display module  31  shows the first sub-screen  32  and the second sub-screen  33 . The second sub-screen  33  is normally shown on the display module  31 . Each of the zones  331 ,  332 ,  333  and  334  is a rectangular frame, a square frame or any other polygonal frame or in motion pictures. The account zone  331  shows the account and identification of the user. The time-and-address zone  332  shows the time and IP address about the downloading of the AV data  11  and keeps a record on how many times the AV data  11  have been downloaded to the IP address. The bonus zone  333  shows accumulated bonus. The lottery zone  334  shows a lottery number generated by the AV data provider  1 . Thus, the personal data are always shown as well as the AV data  11 . The AV data  11  cannot be spread without the AV data  11 . This prevents illegal copying of the AV data  11 . 
     The present invention has been described via the detailed illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
