  • System and device for data protection and method thereof
    Patent number: 12001571
    Abstract: A method of operating a user device includes: receiving a command from a user to power on the user device, wherein the user device includes information on a restricted zone associated with the user device; detecting, by a monitoring entity of the user device without involvement of any device external to the user device, whether the user device is located within the restricted zone in response to the user device being powered on and before an operating system of the user device is executed; and granting access of the user to the user device by the monitoring entity in response to detecting the user device as being within the restricted zone.

  • Fractional motion estimation method with adaptive mode selection
    Publication number: 20110299596
    Abstract: A fractional motion estimation method including the steps of categorizing search modes of the macroblock into a single mode, a reduced mode, and a full mode; determining a search mode of a to-be-process macroblock according to a predetermined condition; and conducting a fractional motion estimation of a to-be-estimated pixel according to the search mode determined in the aforesaid step. Therefore, the fractional motion estimation method can have the adaptive mode selection to spare some parts of computation for low throughput. In other words, it can effectively enhance efficiency of hardware, to lower power consumption, and to maintain consistent image quality.

  • DEVICE FOR VIDEO DECODING
    Publication number: 20080062019
    Abstract: A device for video decoding is disclosed. It includes at least a pipeline scheduler, a decoding core, a segmented context memory and a context cache. The pipeline scheduler and the decoding core could decrease the time taken in a code-decoding period. The segmented context memory and the context cache could reduce accessing time of reading and writing context values.
