This invention discloses a method of protecting copyright of a digital video work by using a digital password technology and a digital watermark technology to prevent the unauthorized use of a digital video work. Such method adds a password into two color matrixes of such video work in advance, so that when such video work is published on the Internet, it can be played by a specified player. As long as a user enters the correct password into the specified player, a full visual effect of such video work can be obtained. If other players are used to play such video work, only partial gray-scale visual effect can be obtained. Users must request or buy a specific player and a password from the distributor of such video work to play the complete information to prevent piracy.

A method for converting monochrome images to color images. A monochrome image is blocked first, and pixel values of monochrome image blocks are obtained by statistical analysis. The monochrome image is then processed by layered mapping and color values of equal grayscale layers thereof are obtained. Finally, each monochrome image block is matched to a color of a corresponding equal grayscale layer.

The present invention discloses an input equipment with a sensed movement feedback, which comprises a pressure sensor pad having a through hole at the center, a rolling ball disposed in the through hole with part of the rolling ball exposed and protruded therefrom, and at least one driver contacting with the surface of the rolling ball. The sensor pad will produce a signal according to a pressing force exerting thereon and transmit the signal to a control circuit of the input equipment, enabling the control circuit to produce a rolling signal for activating the driver to move the rolling ball in a direction proportion to the pressing force. Thus, the user can sense the direction and speed of the cursor movement on the screen from sensing the rolling movement of the rolling ball.

The present invention is to provide a method of automatically enabling or disabling backlight of an electronic device based on a predetermined time, which is implemented in the electronic device including a memory having an established backlight control database containing a predetermined enabled and disabled time of backlight respectively. In response to a user pressing a key of the keypad as determined by the electronic device, the electronic device is able to automatically read and inquire the predetermined enabled or disabled time of backlight, and activate or deactivate the keypad backlight immediately when a predetermined condition (i.e., the predetermined enabled or disabled time of backlight) has been reached.

An over-current alerting circuit used in a hand held device includes a current sensor module, a photo sensor module and an alerting module. The current sensor module is used for sensing a loading current of the hand held device and outputting a photo signal according to the intensity of the loading current. The photo sensor module is used for generating a driving signal when the intensity of the photo signal is higher than a predetermined intensity. The alerting module is used for performing an alerting action after the driving signal is received. In addition, an over-current alerting method is also disclosed herein.
摘要:
A data protection method. The data protection method is implemented between a server and a mobile communication device capable of wireless communication with the server. The mobile communication device transmits a media download request to the server for downloading of media data. The server receives the media download request and then generates a description file, a protected media file and a license file. The description file comprises download information of the protected media file and the license file. The protected media file comprises a set of encrypted data generated from encrypting the media data. The license file comprises a decryption key for decrypting the encrypted data into the requested media data. The server transmits the description file to the mobile communication device. The mobile communication device receives the description file from the server.
