    摘要: An apparatus deblock filters in a digital moving picture processing system with a macro block having a predetermined number of pixel blocks. An external memory controller reads a current sub-block of a current macro block from entire image data stored in an external memory, and delivers image data of an internal pixel block constituting the current sub-block and an external pixel block to a filter-dedicated memory. The filter-dedicated memory stores the delivered image data. A filtering operator performs horizontal filtering on the current sub-block using the stored image data according to a predetermined order, and performs vertical filtering on the current sub-block according to a predetermined order when the horizontal filtering is completed. The external pixel block includes pixel blocks adjacent to a top and a left side among pixel blocks adjacent to the internal pixel block.

    摘要: A method and apparatus for controlling a backlight of a portable display device for a portable communication system are disclosed. The method for controlling a backlight of a portable display device includes calculating a power adjustment coefficient by using information sensed according to a state where the portable display device makes contact with a human body, and adjusting power to be supplied for the backlight according to the calculated power adjustment coefficient. The portable display device controls the amount of power to be supplied according to states where the portable display device makes contact with a human body or is close to a human body to provide only a required amount of power, thus, it is possible to supply power for a longer period of time.

    摘要: A method for soft-combining MBMS (Multimedia Broadcast/Multicast Service) data in an asynchronous mobile communication system including a user equipment (UE) and a radio network controller (RNC), wherein the system provides an MBMS service. In the method, the RNC measures a round trip delay (RTD) for a primary cell in which the UE is located, and an RTD for each of the neighbor cells neighboring the primary cell. The RNC transmits the MBMS data at the same transmission time by considering the RTDs for the primary cell and the neighbor cells so that the UE can receive requested MBMS data. The UE receives MBMS data transmitted from the respective cells at the same transmission time, and performs soft combining on the received MBMS data.

    摘要: A method of designing an optimum encryption algorithm and an optimized encryption apparatus are disclosed. In the encryption apparatus, a function block produces a first ciphertext of length 2n by encrypting a first plaintext of length 2n with an encryption code of length 4n generated from a key scheduler, and a second ciphertext of length m by encrypting the first ciphertext with a second plaintext of length m under the control of a controller. A memory stores the second ciphertext.
