  • Publication number: 20080091943
    Abstract: A data security device and the method thereof are provided for transmission security via a USB port. A USB protocol analyzer of the data security device is provided for determining the signal type, so as to encrypt a storage data signal but not a command signal. Therefore, the part of the USB device not for storage (such as a mouse) can work normally. The data security device determines the file system format of the storage data signal by a file system analyzer and encrypts a data block of the storage data signal by an encrypt unit, thereby a filename of the encrypted storage data signal can be obtained and the USB device can be used on other hosts.

  • Patent number: 7027514
    Abstract: A distributed video stream decoding system on computer and decoding method of the system is proposed to increase the decoding efficiency. The decoding method reads pictures of video stream and divides each picture into a plurality of slice packages through software modules executing on a CPU. Then, the method dispatches the slice packages by slice dispatcher and sends at least a slice into a master decoder when the slice queue of the master decoder less then a default value and sends a slice into a secondary decoder when the secondary decoder is waiting, respectively. Therefore, the master decoder and the secondary decoder can decode the received slice simultaneously to increase the decoding efficiency.
