    • A system and method is described for storing, controlling and accessing multimedia messages, like voice mail, email, video mail and short messages in a communications network, including the Internet or Intranet (202) and any other data or telephony network (206, 207). The communications network (202, 206, 207) comprises one or more storage facilities (201a, 201b, and 201c) for storing messages destined to be received by an intended receiver (209). A sender (208) of a message is provided control over the storage and access of the messages in the one or more storage facilities (201a, 201b, and 201c). The storage facilities (201a, 201b, 201c) may be directly assigned to the sender (208). The storage facilities (201a, 201b, 201c) may be distributed over the communications network (202, 206, 207) and dedicated to or optimized for a particular type of message.

    • In an audio transmission system, an input signal is split up into two spectral portions in a transmitter. These spectral portions are coded by their own respective coder. The low-frequency signal portion is coded by a regular narrow-band coder and the high frequency portion is coded using a coder that outputs LPC codes and signal amplitude codes. In the receiver, the low frequency signal portion is reconstructed by a narrow-band decoder and the high frequency portion is reconstructed by applying a high pass filter to a white noise signal and applying an LPC filter that is controlled by the LPC codes to this filtered white noise signal and adjusting the signal amplitude with an amplifier that is controlled using the amplitude codes of the transmitter. The reconstructed low frequency signal and the reconstructed high frequency signal are then combined to yield a reconstructed output signal containing both frequency ranges.
    • 在音频传输系统中,输入信号在发射机中被分成两个频谱部分。 这些频谱部分由其各自的编码器编码。 低频信号部分由常规窄带编码器编码,并且使用输出LPC码和信号幅度码的编码器对高频部分进行编码。 在接收机中,低频信号部分由窄带解码器重构,高频部分通过对白噪声信号施加高通滤波器并将由LPC码控制的LPC滤波器应用于该滤波器 白噪声信号,并用放大器调节信号幅度,该放大器使用发射机的幅度码进行控制。 然后将重构的低频信号和重建的高频信号组合以产生包含两个频率范围的重构输出信号。

    • A transmission system with a transmitter and a receiver. The transmitter has a speech encoder with analysis means, has calculation means, and has control means. The receiver has a speech decoder. Through a transmission medium, the transmitter transmits frames of data to the receiver. The analysis means determine analysis coefficients from a speech signal. From a bitrate setting, the calculation means calculate a fraction of the frames of data to carry more information about the analysis coefficients than a remaining number of the frames of data. The control means control the transmitter to transmit the fraction of the frames of data and to transmit the remaining number of the frames of data. The receiver receives the frames of data. The receiver derives a reconstructed speech signal from the received frames of data.
    • 具有发射机和接收机的传输系统。 发射机具有分析装置的语音编码器,具有计算装置,并具有控制装置。 接收机具有语音解码器。 通过传输介质,发射机向接收机发送数据帧。 分析意味着从语音信号确定分析系数。 从比特率设置,计算装置计算数据帧的一部分以携带关于分析系数的更多信息,而不是数据帧的剩余数量。 控制装置控制发射机发送数据帧的分数,并发送数据帧的剩余数量。 接收器接收数据帧。 接收器从接收的数据帧导出重构的语音信号。
