  • Patent number: 7388911
    Abstract: An FM broadcast transmitter transmits a broadcast signal having a carrier at a broadcast frequency and sidebands, able to be transmitted at full power, within a transmission bandwidth around the carrier. It includes a source of a modulated FM stereo signal having a carrier at the broadcast frequency and having sidebands with a bandwidth less than the transmission bandwidth representing a stereo signal. It also includes a source of a modulated in-band-on-channel (IBOC) signal, having carrier pulses spaced relative to each other to represent the IBOC digital data signal encoded as a variable pulse width encoded signal, and a bandwidth within the transmission bandwidth not overlapping the FM stereo signal sidebands. A signal combiner combines the modulated FM stereo signal and the modulated IBOC signal to form the broadcast signal.

  • Patent number: 7359303
    Abstract: An asynchronous transfer mode digital document delivery system is provided. A customer premise unit is configured to permit a customer to order and receive a data stream. A buffer is coupled to the customer premise unit to store the data stream before transmitting the data stream to a customer.

  • Publication number: 20070071218
    Abstract: A method for implementing a customized ring back tone service includes: upon receiving a call initiated by a caller, an SSP triggers the call to an SCP, and the SCP requests the SSP to report a detected alerting event of a callee and continue with the call handling; the SSP routes the call to the callee, reports the detected alerting event of the callee to the SCP, splits the call into a call segment associated with the caller and a call segment associated with the callee, and routes the call segment associated with the caller to an IP; the IP plays a ring back tone customized by the callee to the caller. The invention improves the implementation of the customized ring back tone service and ensures that no ring back tone will be played to the caller when the callee is not idle without modifying the existing protocols.

  • Patent number: 7042959
    Abstract: Variable Aperture Coded (VAC) signals for VAC modulation are advantageously generated by a digital signal processor (12) that yields a VAC signal having a single narrow peak in the positive frequency region. A Discrete-Time Hilbert transformer (12) isolates only the positive spectral peaks, thus yielding a VAC signal that affords greater control over zero crossings.

  • Patent number: 6956875
    Abstract: Variable bit rate information is transmitted across a transmission link (20) at a constant bit rate by multiplexing individual variable bit rate elementary data streams (161 and 162) into a composite data stream (18) having a constant bit rate. A receiving device (22) receives the constant bit rate stream but delays processing thereof by an interval typically a fraction of the transmission interval. Following the delay interval, the receiving device processes the data at a rate that is independent of, but typically not greater than, the constant bit rate.

  • Patent number: 6862317
    Abstract: A digital data modulator is coupled to a source of a digital data signal. An encoder encodes the digital data using a variable pulse width code. A pulse signal generator generates pulses representing edges of the encoded digital data signal. A carrier signal generator generates a carrier signal having carrier pulses corresponding to the pulses from the pulse signal generator. A corresponding digital data demodulator is coupled to a source of a modulated signal having carrier pulses spaced relative to each other to represent a variable pulse width encoded digital data signal. A detector generates a variable pulse width encoded signal in response to received carrier pulses. A decoder decodes the variable pulse width encoded signal to generate the digital data signal.

  • Patent number: 6775324
    Abstract: A variable aperture coding/decoding system suitable for use in a spread spectrum system provides multiple phase coding of an input NRZ bitstream. Each bit of a coded output signal is coded to encompass a predetermined different number of clock periods depending on the logic level of the input signal. A coded bit exhibits a predetermined reference number of clock periods, eg., 9, when the input signal does not exhibit a logic level transition. When the input signal exhibits a phase change from a 0 to a 1 logic level, the bit width of an associated coded bit is increased by 1 clock period, to 10 clock periods. When the input signal exhibits a phase change from a 1 to a 0 logic level, the bit width of an associated coded bit is decreased by 1 clock period, to 8 clocks periods. Thus the coded output signal may contain three types of information represented by a bit width change proportional to predetermined factor N.
