  • Patent number: 8516042
    Abstract: A client repeatedly transmits a firmware request including an obtaining start address and an obtaining data length. The obtaining start address indicates the first address of firmware data to be obtained from the server by the client. The obtaining data length indicates the length of the firmware data to be obtained from the server by the client with respect to each firmware request. The server receives the firmware request from the client repeatedly and returns the firmware data for the obtaining data length from the obtaining start address with respect to each firmware request. The client further obtains the firmware data returned from the server repeatedly and updates the firmware by using the firmware data obtained from the server.

  • Publication number: 20130151544
    Abstract: An apparatus for processing content data may include a memory. The apparatus may also include a buffer controller, which may be configured to overwrite recorded content data stored in the memory with new content data. The buffer controller may also be configured to receive a command signal indicative of a search request. Additionally, the buffer controller may be configured to, in response to the command signal, stop the overwriting. In addition, the apparatus may include a result display unit, which may be configured to generate a display signal to cause display of information regarding content represented by at least a portion of the recorded content data.

  • Patent number: 8412801
    Abstract: Each of servers in a global list server system includes a local list of music piece data stored by the each server and a global list of the music piece data stored by the servers. A client requests an arbitrary server to provide the global list and the server transmits the global list to the client upon receiving the request. The client refers to the global list and requests a server storing desired music piece data to transfer the music piece data. The server transmits music piece data to the client upon receiving the transfer request for the music piece data.

  • Patent number: 8280442
    Abstract: Even if a receiver has a normal gain and a lowered intermodulation distortion characteristics, a fault detection is possible. A test signal transmitter sends a test signal having at least two frequencies to a radio receiver through a coupler. A digital signal processing section receives a signal which includes an IM3 component generated by the radio receiver and measures the electric power of fundamental wave components and the IM3 component. Then, the digital signal processing section calculates the gain of the radio receiver and IIP3, which is an index for intermodulation distortion characteristics, of the radio receiver 207 from the calculated electric power. A base station control section determines whether the gain and IIP3 of the radio receiver fall in predetermined ranges to determine whether the radio receiver works normally or has a fault.

  • Patent number: 8140106
    Abstract: The function of comparing power of a signal obtained by multiplying an input signal by an EVM target value and power of a peak suppression signal, and automatically adjusting a peak factor threshold value Vt in such a manner that the values of both power become equal to each other, is added to the peak factor reduction device. The peak factor reduction device is also added with the function of comparing instantaneous amplitude values of a signal Sout after a peak factor reduction and the peak factor threshold value Vt, and automatically calculating a peak detection width N so as to suppress the residual of each peak.
