Abstract:
A multimedia disk box has a housing and a chip used to input, output, and save a signal such as speech or multimedia data. In addition to the function of holding a multimedia disk, the multi-media disk box provides other functions of added value, including recording, playing, and providing encryption/decryption.

Description:
BACKGROUND OF INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a multimedia disk box, and more particularly, to a multimedia disk box with a chip.  
         [0003]     2. Description of the Prior Art  
         [0004]     With development of multimedia processing technology, digital multimedia provides users with access to widespread applications. For example, Compact Disks (CDs), Video Compact Disks (VCDs), and Digital Video/Versatile Disks (DVDs) are used to record and store music, software, images, and video. Digital versatile disks have multiple formats such as SACD, DVD-Audio, DVD-Video, DVD-ROM (Read Only Memory), DVD-RAM (Random Access Memory), and DVD-R. Multimedia disks not only reduce physical storage space for selling disks effectively but also allow users to exchange and enjoy plentiful audiovisual information conveniently. Many companies design all kinds of multimedia disk boxes to appeal to consumers, and such designs typically address the style, the structure and the capacity of a box.  
         [0005]     Please refer to  FIG. 1 .  FIG. 1  shows a diagram of a prior art multimedia disk box  10 . The multimedia disk box  10  comprises a recess  12  for holding a multimedia disk  18 . However, the multimedia disk box  10  only serves the functions of storage and disk preservation, and does not provide other functions of added value. In addition, the proliferation of recording devices intensifies the problems of multimedia copyright. Thus, how to develop an effective mechanism to manage information and protect copyright is a most important issue.  
       SUMMARY OF INVENTION  
       [0006]     It is therefore a primary objective of the claimed invention to provide a multimedia disk box with a chip.  
         [0007]     According to the claimed invention, a multimedia disk box comprises a housing, which comprises a recess for holding at least a multimedia disk, and a chip in the multimedia disk box for storing and outputting a signal.  
         [0008]     It is an advantage of the claimed invention that the multimedia disk box has a chip that can provide functions of added value. For example, the chip can store music, speech, or other multimedia data for disk introduction or personalized applications. In addition, the chip also can be used to store signals for encryption/decryption.  
         [0009]     These and other objectives of the claimed invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

     DETAILED DESCRIPTION  
       [0014]     Please refer to  FIG. 2 .  FIG. 2  shows a diagram of a multimedia disk box  20  according to the present invention. The multimedia disk box  20  comprises a recess  22 , a chip  24 , and an input control switch  26 . The multimedia disk box  20  is made of plastic (such as acrylic), cardboard, or other suitable material. The recess  22  is used to hold a CD or DVD  28 . The cover of the multimedia disk box  20  covers the recess  22  by way of a mechanism such as pasting, wrapping, or clipping. The cover of the multimedia disk box  20  also can be connected to the recess  22 . The chip  24  is embedded or pasted at some position on or in the multimedia disk box  20  for providing users or sales outlets added value functions. The input control switch  26  controls the functions of input and output. The chip  24  can receive and store a signal when the input control switch  26  is turned on, while the chip  24  can output the stored signal when the input control switch  26  is turned off.  
         [0015]     Please refer to  FIG. 3 .  FIG. 3  shows a diagram of a dual-disk DVD box  50  according to the present invention. The DVD box  50  comprises two recesses  52 , the chip  24 , and the input control switch  26 . The DVD box is made of plastic (such as acrylic), cardboard, or other suitable material. The recesses  52  are used to hold DVDs  58 . The cover of the DVD box  50  covers the recesses  52  by way of a mechanism such as pasting, wrapping, or clipping. The cover of the DVD box  50  also can be connected to the recess  52 . The chip  24  is embedded or pasted at some position on or in the DVD box  50  for providing users or sales outlets added value functions. The input control switch  26  controls the functions of input and output. The chip  24  can receive and store a signal when the input control switch  26  is turned on, while the chip  24  can output the stored signal when the input control switch  26  is turned off.  
         [0016]     Please refer to  FIG. 4 .  FIG. 4  shows a functional diagram of the chip  24  of the multimedia disk box  20  and the DVD box  50 . The chip  24  comprises a power supply  32 , a control unit  34 , an input device  36 , an output device  38 , and a storage unit  40 . The power supply  32  is electrically connected to the control unit  34 , the input device  36 , and the output device  38 . The control unit  34  is electrically connected to the input device  36  and the output device  38 . The input device  36  and the output device  38  are electrically connected to the storage unit  40 . The power supply  32  may be a Li-type battery, a light-activated battery, a power converter, or similar device for providing a specified power to the control unit  34 , the input device  36 , and the output device  38 . The control unit  34  is further electrically connected to the input control switch  26  shown in  FIG. 2  and  FIG. 3  for switching and controlling all functions of the chip  24 . The control unit  34  controls the input device  36  to receive a signal and store the signal in the storage unit  40 , and controls the output device  38  to output the stored signal. In other words, the control unit  34  transmits an input instruction to the input device  36  when a signal is inputted, which makes the input device  36  receive the signal and the storage unit  40  store the signal. The control unit  34  transmits an output instruction to the output device  38  when a signal is outputted, which makes the output device  38  output the signal stored in the storage unit  40 .  
         [0017]     The input device  36  is a signal port or a recorder for receiving a signal, speech data, or multimedia data. The output device  38  is a signal port or a player for outputting the signal, speech data, or multimedia data stored in the storage unit  40 . In the examples of present invention, the storage unit  40  can be a Read Only Memory (ROM), an Erasable Programmable ROM (EPROM), an Electrically Erasable Programmable ROM (EEPROM), or a Flash ROM. If the storage unit  40  is ROM, users can not input any data and the input control switch  26  as well as the input device  36  can be removed. The data stored in the storage unit  40  can be written by a manufacturer for introducing the content of the multimedia disks. If the storage unit  40  is a flash ROM, users can switch the input control switch  26  to input data. In addition, the storage unit  40  can record the name, price, manufacturing date, or other data of the multimedia disk an can be used to replace a Universal Product Code (UPC). The storage unit  40  can save specified passwords to deal with problems of copyright by an encryption/decryption operation. As a result, the present invention multimedia disk box provides added value functions.  
         [0018]     Those skilled in the art will readily observe that numerous modifications and alterations of the device may be made while retaining the teachings of the invention. Accordingly, that above disclosure should be construed as limited only by the metes and bounds of the appended claims.
