    摘要： An arrangement to automatically change between a scrambled digital data output and descrambled digital data output of a receiver by inserting a control signal conforming to a program provider's policy into a transmission signal. In a receiving side, a descrambler descrambles a channel-decoded signal, a demultiplexer demultiplexes the multiplexed signal from the descrambler into encoded video and audio data for output to a source decoder, and extracts the control information inserted in the transmitting side for output to a switch or CPU. The CPU decrypts a control signal from the control information extracted by the demultiplexer to determine whether the scrambled digital signal or descrambled digital signal is appropriate for output, and outputs a changeover control signal depending on the result of decryption. A switch selects the output of a scrambled digital signal from a stage prior to the descrambler, or a descrambled digital signal from a stage subsequent to the descrambler, depending on the changeover control signal from the CPU. Thereby, a scrambled digital signal output or descrambled digital signal output can automatically be changed over depending on a program provider's policy.

    摘要翻译： 通过将符合程序提供商策略的控制信号插入到发送信号中，在加扰的数字数据输出和接收机的解扰数字数据输出之间自动地改变。 在接收侧，解扰器对信道解码信号进行解扰，解复用器将来自解扰器的复用信号解复用为编码视频和音频数据，以输出到源解码器，并提取插入发送侧的控制信息，以输出到 开关或CPU。 CPU从由解复用器提取的控制信息中解密控制信号，以确定加密数字信号或解扰数字信号是否适于输出，并根据解密结果输出切换控制信号。 切换器根据来自CPU的切换控制信号，选择来自解扰器之前的级的加扰数字信号的输出或来自解扰器之后的级的解扰数字信号。 因此，根据程序提供者的策略，加扰数字信号输出或解扰数字信号输出可以自动地改变。

    摘要： A broadcasting and communication receiver apparatus for displaying programs-associated information (S P ), in which, in addition to a predetermined display zone, another display zone is provided so that display data of specific information selected by a viewer is wholly displayed and, when the display data is displayed as omitted, a symbol indicative of the information omission is attached to the display data to display the display data within the limited display zone. The apparatus comprises a receiver (118) for receiving the program-associated information (Sp) including a title, start and end times of a broadcast program together with a video signal (S V ) and an audio signal (S A ), a decoder (119) for decoding the program-associated information, a display unit (105) for displaying the decoded program-associated information thereon, a command receiver (106) for receiving an input signal from a remote controller or from a key or keys provided to the receiver, and a display controller (109) for controlling a display screen on the basis of the input signal.
