    • A method and apparatus are provided for a first controlled device, such as a wireless local transmitter that accepts a plurality of digital audio signals and corresponding program information signals converted from a controlled source, such as the encoded digital data provided by a digital data signal source, typically a community antenna television (CATV) cable or direct broadcast satellite, then modulates said digital audio and corresponding program information signals on different carrier frequencies and transmits the modulated signals to a plurality of second controlled devices, such as remote digital receiver/tuners that demodulate said signals to output music in stereophonic sound and display the corresponding program information by means of an alphanumeric display. The first and second controlled devices contain microprocessor systems for communicating, controlling, storing, processing, and display of digital data within the operation of the respective system. A high speed, error free digital signal protocol is utilized for transmitting digital audio and corresponding program information signals to and from the digital receiver/tuner. The digital data transmitter and digital receiver/tuners utilize the 44.1 kilohertz (kHz) Compact Disc (CD) clock signal embedded in digital audio signals provided by an established delivery system to derive clocking signals for reception and processing of digital audio signals and for implementing the display information communications protocol.
    • 提供了一种方法和装置,用于第一受控设备,诸如接收多个数字音频信号的无线本地发射机和从受控源转换的相应节目信息信号,诸如由数字数据信号源提供的编码数字数据 通常是社区天线电视(CATV)电缆或直接广播卫星,然后在不同载波频率上调制所述数字音频和对应的节目信息信号,并将调制的信号发送到多个第二受控设备,例如远程数字接收机/调谐器, 解调所述信号以立体声声音输出音乐并通过字母数字显示显示对应的节目信息。 第一和第二受控设备包含用于在相应系统的操作内传送,控制,存储,处理和显示数字数据的微处理器系统。 使用高速,无错误的数字信号协议将数字音频和对应的节目信息信号传送到数字接收机/调谐器和从数字接收机/调谐器传送。 数字数据发射器和数字接收器/调谐器利用嵌入在已建立的传送系统提供的数字音频信号中的44.1千赫(kHz)压缩光盘(CD)时钟信号来导出数字音频信号的接收和处理的时钟信号, 显示信息通信协议。
