    • An encrypted video distribution system includes a signal-originating head end for scrambling the audio portion of outgoing television program-bearing signals. In particular, the audio content of a television program alternately reverses polarity under control of a keyed pseudo random generator. At each authorized subscriber location, a pseudo random generator is included in receiver descrambling circuitry and operates in a sequence identical to the like circuit at the head end to restore the polarity-inverted audio signal, thereby permitting reception and presentation of intelligible audio subject matter.In accordance with another aspect of the present invention, the video information present during selected lines is inverted about a predetermined inversion level and restored at equipped, authorized subscriber stations also under control of the pseudo random generators.
    • 加密的视频分发系统包括信号发起头端,用于加扰输出电视节目承载信号的音频部分。 特别地,电视节目的音频内容在密钥伪随机发生器的控制下交替地反转极性。 在每个授权用户位置,伪随机发生器被包括在接收机解扰电路中,并以与头端相同的序列操作,以恢复极性反转的音频信号,从而允许可理解的音频主体的接收和呈现。 根据本发明的另一方面,存在于所选择的行中的视频信息关于预定的反转电平反转,并且还在伪随机发生器的控制下在配备的授权用户站处恢复。

    • Apparatus forming part of a home entertainment system includes an electronic device having an input accepting a signal corresponding to an externally-generated first user interface, a control module for internally-generating a signal corresponding to a second user interface, and an output for transmitting a combination of the above referenced signals for display. The control module controls an arrangement of display of the first user interface and the second user interface. The apparatus also includes a remote controller for communicating via a two-way communication link with the control module of the electronic device concerning a selection of one of the first user interface and the second user interface. The remote controller having an emitter for emitting control code signals, and the operation of the emitter is controlled by communications received by the remote controller from the control module of the electronic device. A method is also provided.
    • 构成家庭娱乐系统的一部分的装置包括:电子装置,其具有接受与外部生成的第一用户接口相对应的信号的输入;内部生成对应于第二用户界面的信号的控制模块;以及用于发送 组合上述参考信号进行显示。 控制模块控制第一用户界面和第二用户界面的显示布置。 该装置还包括遥控器,用于通过双向通信链路与电子设备的控制模块进行通信,涉及第一用户界面和第二用户界面之一的选择。 具有用于发射控制码信号的发射器和发射器的操作的遥控器由遥控器从电子设备的控制模块接收的通信来控制。 还提供了一种方法。
