    Abstract: A system that enables an event or moments within an event to be captured and provided in a record that preserves at least some aspects of the participant's perspective of the event. In particular, the present invention involves centralized recording of the event in one or more modes including video, audio, and still image recordings and a system that enables a participant (i.e., one who perceives the event) to select portions of the event recording substantially contemporaneously with the event occurrence. A personalized record is made by duplicating the selected portions from the event record. In a particular example, the personalized record is recorded on a digital media such as a compact disc (CD) or digital video disk (DVD) or the like.

  • Patent number: 10051100
    Abstract: A mobile terminal apparatus checks if a user is a proper user based on the operation of the user and, if the result of authentication is negative, uploads predetermined data, which is part of data stored in a memory, to a predetermined server. After the transmission is completed, the mobile terminal apparatus erases the uploaded data from the memory. It is also possible to instruct the mobile terminal apparatus to upload and erase data from an external source using an electronic mail or a telephone tone signal sequence. This may protect data contained in mobile terminal apparatus that has been lost, from a person who improperly attempts to access the data.

  • Patent number: 8184201
    Abstract: A method and apparatus for automatic audio standard detection in terrestrial broadcast signals is disclosed. In one embodiment, a method of detecting automatic audio standard for terrestrial broadcast includes scanning for each known audio frequency standard of interest in a current band energy spectrum in an incoming broadcast signal using a standard of non standard energy estimation algorithm, such as Goertzel DFT or FFT based algorithm for a predetermined time interval. At each known audio frequency standard of interest, energy is computed using the associated standard or non standard energy estimation algorithm within the predetermined time interval. The computed energy at each known audio frequency standard of interest is then compared to predetermined threshold energy. At each known audio frequency standard of interest, it is determined whether the audio frequency standard of interest is detected based on the outcome of the comparison.

  • Publication number: 20120069242
    Abstract: An audio processing device may estimate noise effects at a particular location based on noise measurement data corresponding to one or more noise sources. The audio processing device may modify one or more output audio content transmitted by the audio processing device to that particular location such that the modification may cancel the estimated noise effects at the particular location, at time when the output audio streams are received at that location. The noise effects estimation may also be based on audio reception measurement data at the particular location. The noise measurement data and/or the audio reception measurement data may be generated by audio capturing devices placed at or near noise sources, and/or at or near the particular location, respectively. The noise measurement data and/or the audio reception measurement data may be communicated to the audio processing device using wired and/or wireless connections.

  • Patent number: 8126064
    Abstract: The identification information processing unit receives identification information identifying the reception device from a reception device, and generates decoded identification information indicating the decoded value of the received identification information. The parameter value selection unit selects the first parameter value when the decoded identification information includes an information representing a television, selects a second parameter value that is less than the first parameter value when the decoded identification information includes an information representing an audio device, and generates a selected parameter value. The frequency divider frequency divides the audio clock using the selected parameter value, and generates a frequency division signal. The counter counts one period of the frequency division signal using the pixel clock and generates the cycle time stamp. The transmission device then sends the selected parameter value and cycle time stamp to the reception device.

  • Patent number: 8027485
    Abstract: An audio processing system which allows a surround sound system to utilize the transmission bandwidth efficiently by adaptively transmitting a supplementary data from a secondary source in addition to the audio signals of a primary source. The system consists of a transmitter component, capable of transmitting audio signals from a primary source and adaptively inserts supplementary data of the secondary source in the reserved communication bandwidth. The transmitter inserts headers in the channels used by the supplementary data to allow the receivers to identify the channel allocation between the primary source and the secondary source. Another part of the audio processing system is that of a receiver component which is capable of discriminating between data from the primary source and data from the secondary source.

  • Publication number: 20110170003
    Abstract: An information processing apparatus includes the following elements. A generation unit generates a multiplexed video frame having a predetermined screen size. A dividing unit divides input audio data into audio data items each having samples for one frame period of the multiplexed video frame. A multiplexing unit multiplexes audio data items obtained by dividing each stream of input audio data and number-of-samples information representing the number of samples thereof. A processing unit processes audio data items multiplexed in a multiplexed video frame input from an input video port, and outputs from an output video port thereof a multiplexed video frame in which the resulting audio data items and the number-of-samples information thereof are multiplexed. An extraction unit extracts the audio data items multiplexed in the multiplexed video frame output from the processing unit in accordance with the number-of-samples information. A transmission unit outputs the extracted audio data items to outside.

  • Publication number: 20110026719
    Abstract: A television audio signal encoder includes a device that sums a left channel audio signal and a right channel audio signal to produce a sum signal. The device also subtracts one of the left and right audio signals from the other to produce a difference signal. The encoder also includes a configurable infinite impulse response digital filter that selectively uses one or more sets of filter coefficients to filter the difference signal. The set of filter coefficients is applied to the difference signal by a single multiplier in a recursive manner to prepare the difference signal for transmission.

  • Patent number: 7843514
    Abstract: In a signal transmitter and a signal receiver, a multiplexing part multiplexes a video signal and a time-base-compressed audio signal on the basis of a multiplexing control signal to transmit the multiplexed signal through a data line in the signal transmitter. Further, a demultiplexing part demultiplexes a video/audio multiplexed signal received through the data line into the original video signal and audio signal by a demultiplexing control signal in the signal receiver. According to the so-configured signal transmitter and signal receiver, it is possible to realize a signal transmission system compliant with the DVI standard, in which the audio signal as well as the video signal can be transmitted.

  • Patent number: 7830452
    Abstract: A digital audio encoder, digital video conditioner, and a digital modulator are described for producing a television broadcast signal at a desired channel frequency range. Left and right audio channel signals are digitized and encoded according to a stereo standard and then combined to form a stereo audio signal. A second audio programming channel signal may be included. A video input can be digitized and conditioned to form a digital video channel. The stereo audio signal can be placed directly at a desired channel frequency by frequency modulation without the need for using an intermediate frequency. The digital video channel can be placed at a desired frequency by amplitude modulation. The digital and audio channels can be digitally combined to create a television transmission signal at a desired frequency and according to a desired standard.
