    摘要： Disclosed herein is a circularly polarized antenna with a wide beam width, in which four U-shaped metal strips are disposed in a circular shape, and four signals having the same magnitude and phase difference intervals of 90 degrees are fed to the respective metal strips so as to transceive circularly polarized waves. The disclosed circularly polarized antenna includes a ground plane, a central patch formed in the center of an upper surface of the ground plane, and a plurality of radiation patches disposed above the ground plane and around the central patch in a circular shape, wherein signals having the same magnitude and preset phase differences are fed to respective radiation patches.

    摘要： Disclosed is a broadcasting signal receiving apparatus for controlling use of a broadcasting program using a signature in program information and a method thereof. The broadcasting signal receiving apparatus includes a communicating unit for receiving a broadcasting signal, an extracting unit for extracting a broadcasting program and program information from the received broadcasting signal, and a determining unit configured to generate a temporal signature for confirmation (confirmation signature) which determines whether the program information is changed or not from the original program information and determine validity of the program information by comparing a signature included in the extracted program information with the confirmation signature.

    摘要： A method of assigning a connection identifier for an asynchronous transfer mode switching system, includes the steps of: (a) analyzing a parameter transmitted in a VPI allocation request if it is received, analyzing the number of connections and the number of VPI used in SIM, and confirming whether a VPI desired to be used in VPI allocation request if the input parameter is normal and connection is available; (b) changing the usage state of VPI assigned to a VPI management table if the VPI is designated and this is in no use, increasing the number of VPI and the number of VPI assigned in the connection identifier management table, indicating a VPI assigned, or selecting a VPI in no use in SIM if the VPI is not designated with reference to the VPI management table, and changing the usage state of the VPI assigned in the VPI management table.
