Abstract: A device and a method for monitoring behavior of listening to broadcast comprises a transmitter transmitting a characteristic audio signal which is modulated on a carrier signal; a collector collecting an ambient sound; a detector detecting whether the collected ambient sound contains the characteristic audio signal; and a determiner determining whether a broadcast receiving apparatus receives the broadcasting channel corresponding to frequency of the carrier signal according to the result of the detector.

Abstract: The invention relates to monitoring behavior of listening to broadcast, and it is presented a device and a method for monitoring behavior of listening to broadcast. The device comprises a transmitter transmitting a characteristic audio signal which is modulated on a carrier signal; a collector collecting an ambient sound; a detector detecting whether the collected ambient sound contains the characteristic audio signal; and a determiner determining whether a broadcast receiving apparatus receives the broadcasting channel corresponding to frequency of the carrier signal according to the result of the detector.

Abstract: In general, techniques are described for performing decentralized packet dispatch. A network device comprising one or more service processing units (SPUs) and an interface may implement the techniques. The interface receives a packet associated with a session and selects a first one of SPUs to dispatch the packet based on first information extracted from the packet. The first one of the SPUs dispatches the packet to a second one of the SPUs based on second information extracted from the packet. The second one of the SPUs performs first pass processing to configure the network security device to perform fast path processing of the packet such that second one of the SPUs applies one or more services to the packet and subsequent packets associated with the same session without application of services to the packets by the first one of the service processing units.

Abstract: A method for acquisition of audience rating data of digital television. The method includes: 1) collecting audience information by an acquisition system of audience rating data of digital television, the audience information including individual identification of audiences and individual attribute information corresponding to the individual identification; 2) monitoring data acquisition signals by the acquisition system, collecting appropriate individual identification and individual rating information according to the instructions of the data acquisition signals; and 3) inquiring the individual attribute information of the audiences according to the individual identification, and combining the collected individual rating information and corresponding individual attribute information thereof as a set of original audience rating data for analysis.

Abstract: A software patch is generated by determining the binary differences between a more secure version of the embedded system firmware and the currently operating, vulnerable version. The differences are extracted and analyzed to determine their basis in the source code for the more secure version. Source code that affects the binary differences may be compiled into a binary file and linked, off-line, with the binary executable file that contains the machine code for the currently operating version of the embedded system firmware, producing a security patch. The security patch may be installed on the embedded system at run-time, and it is then executed to modify the currently operating firmware to redirect firmware operation from vulnerable procedures toward the new, secure procedures contained in the software patch.
