    • Auxiliary data is transported in subbands of a primary data signal by hiding the data in the form of colored noise. The colored noise has a spectrum that simulates the spectrum of the primary data signal in each subband. The data to be transported is first converted to a spread spectrum signal. The primary data signal is analyzed to determine its spectral shape. The same spectral shape is imparted to the spread spectrum signal in each subband, which is then combined with the primary data signal for transmission. The spectral shaping can be performed using time domain modeling and synthesis such as linear predictive coding. A plurality of different auxiliary information streams can be transported on the primary data signal. By adjusting the gain of individual spread spectrum signal carrier(s) and the power of the colored noise, the auxiliary information stream(s) can be rendered at any desired level below or above an interference threshold in the primary data signal.
    • 辅助数据通过以彩色噪声的形式隐藏数据而在主数据信号的子带中传送。 彩色噪声具有模拟每个子带中主要数据信号的频谱的频谱。 要传输的数据首先转换为扩频信号。 分析主数据信号以确定其光谱形状。 相同的光谱形状被赋予每个子带中的扩频信号,然后将其与主数据信号组合以进行传输。 可以使用诸如线性预测编码的时域建模和合成来执行频谱整形。 可以在主数据信号上传输多个不同的辅助信息流。 通过调整各个扩展频谱信号载波的增益和有色噪声的功率,辅助信息流可以在低于或高于主数据信号中的干扰阈值的任何期望的水平处呈现。

    • A system for measuring exposure to a visual display such as a billboard. A transmitter that is proximate to the billboard broadcasts a data signal that carries information relating to the billboard. This information may identify the location of the billboard, the message displayed by the billboard, and time of day. The data signal is provided at a power level that is adapted to reach a pre-defined exposure area in which the billboard can be viewed. A portable receiving device is provided to a defined consumer population to measure the exposure of the consumers to the billboards. The receiving device may be carried or worn by the consumer, or carried in the consumer's vehicle. The receiving device is adapted to recover the data signal and store the information relating to the billboard when the viewer is in the pre-defined exposure area. The time of day and duration of the exposure may also be recorded. The recorded information is subsequently downloading for processing by a central processing facility, e.g., via a telephone line or computer link.
    • 用于测量诸如广告牌的视觉显示器的曝光的系统。 靠近广告牌的发射机广播携带与广告牌有关的信息的数据信号。 该信息可以标识广告牌的位置,广告牌显示的消息和时间。 数据信号被提供在适于达到其中可以观看广告牌的预定曝光区域的功率水平。 将便携式接收设备提供给定义的消费者群体以测量消费者对广告牌的暴露。 接收设备可以由消费者携带或佩戴,或携带在消费者的车辆中。 接收装置适于在观看者处于预定义的曝光区域时恢复数据信号并存储与广告牌相关的信息。 也可以记录暴露时间和持续时间。 所记录的信息随后被下载以供中央处理设施处理,例如经由电话线或计算机链路。

    • Broadcast audio is automatically monitored for information of interest. A computer processor has a memory associated therewith for storing a vocabulary of keywords of interest. An audio receiver receives an audio broadcast. A speech recognition system associated with the audio receiver and computer processor detects when one of the keywords appears in a received audio segment. A report generator associated with the computer processor and responsive to the detection of a keyword generates a report detailing the detected keyword and its context. The system is particularly well suited to the verification of commercial messages and to assist in public relations efforts.
    • 自动监视广播音频以获取感兴趣的信息。 计算机处理器具有与其相关联的存储器,用于存储感兴趣的关键词的词汇。 音频接收器接收音频广播。 与音频接收器和计算机处理器相关联的语音识别系统检测何时关键字之一出现在接收的音频段中。 与计算机处理器相关联并响应于关键字的检测的报告生成器生成详细描述检测到的关键字及其上下文的报告。 该系统特别适合商业信息的验证,并协助公关工作。
