  • PWM buffer circuit for adjusting a frequency and a duty cycle of a PWM signal
    Patent number: 7772902
    Abstract: A PWM buffer circuit includes a duty cycle converting circuit and a frequency-fixed PWM signal generating circuit. The duty cycle converting circuit is used for receiving a first PWM signal and then generating a duty cycle reference voltage on the basis of the first PWM signal. The duty cycle reference voltage is a one-to-one mapping function of the first duty cycle. The frequency-fixed PWM signal generating circuit is used for receiving the duty cycle reference voltage and then outputting a second PWM signal with a fixed frequency. The second PWM signal has a second duty cycle, which is determined in accordance with the duty cycle reference voltage. In addition, the second duty cycle is a one-to-one mapping function of the duty cycle reference voltage.

  • Method for effectively transmitting control signal in wireless communication system
    Patent number: 7774686
    Abstract: A method of performing HARQ performed by a user equipment (UE) is provided. The method includes receiving a bundling indicator which indicates the number of bundled downlink subframes, determining whether at least one bundled downlink subframe is missed by comparing the bundling indicator with the number of detected bundled downlink subframes, generating a representative ACK/NACK signal when no bundled downlink subframe is missed, and transmitting the representative ACK/NACK signal on an uplink channel. Recovery capability is maximized and the packet loss is reduced in such a situation that less number of ACK/NACK signals are fed back than that of downlink packets.

  • Video decoding system with external memory rearranging on a field or frames basis
    Patent number: 7773676
    Abstract: A video decoding system is provided. When a DDR SDRAM is used as an external memory, MBs are rearranged and then stored to minimize memory access operations for the MBs at the DDR SDRAM and unnecessary additional word read operations caused by a DDR characteristic. Accordingly, the video decoding system can efficiently perform a memory access operation on MBs for video display and frame decoding by the video decoder. Specifically, the decoding system can reduce the total video decoding time, thereby allowing a surplus memory use time for additional functions of a digital broadcasting receiver.

  • Pre-loaded force sensing resistor and method
    Patent number: 7772960
    Abstract: A force sensing resistor (FSR) includes a substrate having separated electrically conductive traces and another substrate having a resistive layer in which the substrates are subjected to a biasing force such that the substrates contact one another with the resistive layer electrically connecting the traces with a resistance inversely dependent on the biasing force. Upon an external force applied towards a substrate, the substrates contact one another with a total force which is the sum of the forces with the resistive layer electrically connecting the traces with a resistance inversely dependent on the total force. An FSR output which is a function of the resistance is measured. Whether a change in magnitude of the FSR output during a time interval is greater than a threshold is determined. A touch applied on the FSR is detected during the time interval if the change is greater than the threshold.

  • Player, and source switching method for recording and playback apparatus
    Patent number: 7773854
    Abstract: In a player, for example, when a memory card is loaded as a removable medium during playback of a CD, an audio-output-source selecting unit switches the output state to playback of the memory card in normal operation. However, in a case in which a medium-loading detecting unit detects that a memory card is not loaded at the time when a request for recording on the memory card is entered during the playback of a CD, and a medium-loading-time detecting unit detects that the memory card is loaded within a predetermined time, the audio-output-source selecting unit immediately starts recording on the memory card without switching the output state to the playback of the memory card.

  • System and method for partially encrypted multimedia stream
    Patent number: 7773750
    Abstract: A multimedia stream head end includes a legacy conditional access (CA) device that fully encrypts the stream using legacy keys. A copy of the stream is sent to a secondary CA device that encrypts only critical packets in the stream using secondary keys to render a partially encrypted stream. The critical packets in the fully encrypted stream from the legacy CA device are obtained and inserted next to the corresponding critical packets in the partially encrypted stream. Thus, only critical packets are encrypted, with encrypted versions being generated by both the legacy CA and secondary CA without the legacy CA knowing which of the packets that it encrypts are “critical”.
