  • Patent number: 8230101
    Abstract: Transfer control means (41) transfers part of held digital contents in an internal storage device (51) to a network storage device (57). List information presentation means (42) returns list information which makes the digital contents stored in the internal storage device (51) and the network storage device (57) as the held digital contents in response to a list presentation request for the held digital contents. Upon reception of a data transmission request, search means (43) searches where the held digital contents are currently stored. If the result of the search shows the network storage device (57), content data transmission processing means (44) allows the stream-delivery of the data from the network storage device (57) to a network player (56). There is provided a server device for media (40) capable of maintaining the convenience of playback in a network player, while properly dealing with the large total size of held digital contents.

  • Patent number: 8214216
    Abstract: A simply configured speech synthesis device and the like for producing a natural synthetic speech at high speed. When data representing a message template is supplied, a voice unit editor (5) searches a voice unit database (7) for voice unit data on a voice unit whose sound matches a voice unit in the message template. Further, the voice unit editor (5) predicts the cadence of the message template and selects, one at a time, a best match of each voice unit in the message template from the voice unit data that has been retrieved, according to the cadence prediction result. For a voice unit for which no match can be selected, an acoustic processor (41) is instructed to supply waveform data representing the waveform of each unit voice. The voice unit data that is selected and the waveform data that is supplied by the acoustic processor (41) are combined to generate data representing a synthetic speech.

  • Patent number: 8213341
    Abstract: In a mobile telephone terminal at the transmitting end, voice data to be transmitted are sequentially inputted, and it is determined whether the inputted voice data are silent. The voice data regarded as silent voice are replaced by group numbers, while the voice data indicative of sonant voice as well as the group numbers as replaced are transmitted by wireless. On the other hand, in a mobile telephone terminal at the receiving end, the signals transmitted by wireless are received, and the voice data and group numbers of the received signals are discriminated. The voice data are reproduced as they are, while the group numbers are reproduced as silent, and further processings based on the group numbers are executed. This allows predetermined data to be repetitively transmitted with a high efficiency without degrading communication quality very much. This also facilitates a follow-up participation in a group call.

  • Patent number: 8199854
    Abstract: An encoder encodes sound data and the like to generate a binary signal. A mapper converts the binary signal into a four-level symbol and outputs the four-level symbol. A base band filter includes a root raised cosine filter and a sinc filter. The base band filter blocks a predetermined frequency component of a symbol to shape the symbol into a waveform signal and outputs the waveform signal shaped. An FM modulator transmits a signal subjected to FM modulation according to a magnitude of an amplitude of a waveform signal to a receiving unit. When a symbol of ±3 is outputted from the mapper, a frequency shift of a signal transmitted from the FM modulator has a predetermined value in a range of ±0.822[kHz] to ±0.952[kHz]. This makes it possible to provide a modulating apparatus, a mobile communication system, a modulating method, and a communication method that use a modulating method that can conform to the FCC rule to be enforced in 2005 without using a linear power amplifier.

  • Publication number: 20120020494
    Abstract: In signal-component extraction, an input signal is delayed to generate a delayed input signal. The input signal is adaptively filtered with filter coefficients, to generate a filtered signal. The filtered signal is subtracted from the delayed input signal to generate an error signal. A preset reference value is divided by an amplitude of the input signal to generate a gain value. The filter coefficients are derived based on a value obtained by multiplying the input signal and error signal by the gain value or a square of the gain value.

  • Publication number: 20120001800
    Abstract: A position detecting apparatus includes a GPS receiver configured to catch one or more of GPS satellites and track one or more of the satellites while receiving a GPS signal or GPS signals from one or more of the satellites. A power supply controllably feeds power to the GPS receiver. A suspension time decider decides a suspension time in accordance with at least one of (1) the number of satellites caught by the GPS receiver and (2) the level of at least one of the received GPS signals, and determines whether or not the lapse of time during which the GPS receiver continues to track no satellite reaches a prescribed time. A suspension controller controls the power supply to suspend the power feed to the GPS receiver during a term equal in length to the decided suspension time in cases where the lapse of time reaches the prescribed time.

  • Patent number: 8023585
    Abstract: A bit adding part acquires RSSI as measured by an RSSI measuring part, and adds “1” to each bit of protected audio data of an audio vocoder, if the acquired RSSI is smaller than a predetermined threshold value. If the acquired RSSI is equal to or greater than the predetermined threshold value, the bit adding part adds the bits of additional data to the respective bits of the protected data of the audio vocoder. A frame recovery part separates upper and lower order bits of deinterleaved data, and determines, based on CRC, whether eight data parts as obtained by combining the lower order bits as separated are valid. If so, the frame recovery part combines the eight data parts as the additional data to recovery additional information. In this way, additional data can be efficiently transmitted, while error correction being performed in accordance with communication environment.
