  • Patent number: 7317796
    Abstract: A system and method of video stream encryption. A storage device stores a first quantization scale and a second quantization scale. An encryption application receives video data, a first quantization scale and a second quantization scale, generating quantized data by dividing the video into the first quantization scale, generating supplementary data by subtracting the quantized data multiplied by the first quantization scale from the video data, generating quantized supplementary data by dividing the supplementary data into the second quantization scale, and generating encrypted quantized supplementary data using variable length encoding and symmetrical/asymmetrical encryption algorithm.

  • Publication number: 20060083306
    Abstract: A video decoding method. The first frame of video data is acquired, the first frame is assigned to the backward reference frame and the forward reference frame respectively, and a frame buffer is emptied. Next, the next frame of the video data is acquired, and frame type is then determined. If the frame is a B-frame, corresponding decoding operations are implemented according to the determining result, and the frame is temporarily stored in the frame buffer.

  • Publication number: 20050114669
    Abstract: An image protection system and method. The system includes at least an image compression/encryption device having a compression unit, an encryption unit and an image composing unit. The compression unit separates an image into base image data and auxiliary image data according to a compression technique, and compresses the base image data to compressed base image data according to the compression technique. The encryption unit encrypts the auxiliary image data to an auxiliary image data cipher. The image composing unit composes the compressed base image data and the auxiliary image data cipher into a protected image corresponding to the image.

  • Publication number: 20050062721
    Abstract: An optical pointer includes a housing, a movable plate, a manipulable member and a displacement detecting unit. The movable plate is disposed in the housing and has a recognizable pattern. The manipulable member is manipulated by a user to transmit the movable plate to effect two-dimensional movement inside the housing. The displacement detecting unit is disposed in the housing for optically detecting the recognizable pattern of the moveable plate, and generating a control signal indicative of a displacement of the movable plate according to detected image change of the recognizable pattern.
