Patents by Inventor Leung Chee-Chun

Leung Chee-Chun has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8194114
    Abstract: The invention discloses a high definition video conference system comprising a plurality of transmitting terminals and a receiving terminal. Each transmitting terminal comprises a digital imaging/processing apparatus and a first data processing apparatus. The receiving terminal comprises a second data processing apparatus and at least one display apparatus. The digital imaging/processing apparatus is used for capturing an image of a participant and for compressing the captured image into a high definition image. According to a standard communication protocol, the first data processing apparatus converts the high definition image into a standard-format communication image and then transmits the standard-format communication image. The second data processing apparatus is used for receiving and decoding the standard-format image transmitted from each transmitting terminal into the high definition image. Accordingly, the high definition can be displayed on the display apparatus.

  • Patent number: 8120639
    Abstract: The invention provides a high-definition video conference system and method. The high-definition video conference system, according to the invention, uses an encoding module for compressing a plurality of usable digital signals under a high-definition compression standard into a plurality of compressed digital signals, and an instant-messaging application for transmitting the compressed digitals to a second terminal apparatus. The second terminal apparatus uses a decoding module for decompressing the plurality of compressed digital signals under the high-definition compression standard to obtain a plurality of image signals, and a displaying module for displaying the image signals. Therefore, the high-definition video conference system of the invention can achieve high-definition video conference applications even under limited hardware performance and network transmission bandwidth.
