  • Publication number: 20080184323
    Abstract: A communication apparatus with a network multimedia playback function includes a network dialup module, a multimedia module and a communication exchange module. The network dialup module can receive an electronic signal from a regular telephone wire and analyze the electronic signal to obtain an analog network packet or an audio/video packet, and processes the analog network packet into a network data and sends the network data to a computer. The multimedia module receives the audio/video packet from the network dialup module, and processes the audio/video packet into an audio/video data and sends the audio/video data to a display apparatus. The communication exchange module is provided with a voice splitter that analyzes the electronic signal to obtain a voice signal of low frequency and sends it to the communication exchange module. Thus, the communication apparatus provides the functions of a network connection, a multimedia playback, and a dialing of Internet phone.

  • Patent number: 7286668
    Abstract: 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 password protection of two chrominance arrays of such video work in advance, so that when such video work is published on the Internet, it can only be played in color by a specified player. As long as a user enters the correct password into the specified player, a full color visual effect of such video work can be obtained. If other players are used to play such video work, only a 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.

  • Patent number: 7098890
    Abstract: 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.
