    • Teletext data stored in a video RAM is developed in a work RAM. A CPU selectively deletes picture elements from the developed teletext data, to thereby compress the teletext data into data adapted for display in an auxiliary screen which is e.g., 1/4 of the display screen of a CRT. The compressed teletext data is written into the video RAM. A display controller supplies the compressed teletext data stored in the video RAM to a synthesizing circuit, together with an appropriate display switching signal representing a timing for switching between the compressed teletext data and a TV broadcast video signal. In accordance with the display switching signal, the synthesizing circuit selectively supplies the TV broadcast video signal and the compressed teletext data to a video output circuit. Accordingly, the teletext picture compressed to a 1/4 size is displayed on the display screen of the CRT as an auxiliary screen image, while being superimposed on the TV picture.
    • 存储在视频RAM中的图文电视数据在工作RAM中开发。 CPU从显影的图文电视数据中选择性地删除图像元素,从而将图文数据压缩成适合于在例如CRT的显示屏幕的1/4的辅助屏幕中显示的数据。 压缩的图文电视数据被写入视频RAM。 显示控制器将存储在视频RAM中的压缩图文电视数据与表示用于在压缩图文电视数据和TV广播视频信号之间切换的定时的适当的显示切换信号一起提供给合成电路。 根据显示切换信号,合成电路选择性地将TV广播视频信号和压缩图文数据提供给视频输出电路。 因此,压缩成1/4尺寸的图文电影图像作为辅助屏幕图像显示在CRT的显示屏上,同时被叠加在TV图像上。

    • A transmission signal includes a framing code and a data signal following the framing code. The framing code has a predetermined pattern which can be identified even if a bit error occurs therein. A signal fetcher fetches the transmission signal upon detecting the framing code which is included therein, on the basis of a reference signal. A framing code detector compares an output from the fetcher with pattern data corresponding to a predetermined pattern of the framing code. If the output has a bit error with respect to the pattern data, the detector generates a first framing code-detection output, for supply to the fetcher, as a signal for providing the timing. However, if the output coincides with the pattern data, the detector generates a second framing code-detection output. A reference signal generator generates the reference signal for the fetcher, in correspondence with the second framing code-detection output.
    • 发送信号包括成帧代码和跟随成帧码的数据信号。 成帧代码具有预定的模式,即使在其中发生位错误也能够识别。 基于参考信号,信号读取器在检测到包含在其中的成帧代码时取出发送信号。 成帧代码检测器将来自提取器的输出与对应于成帧代码的预定模式的模式数据进行比较。 如果输出相对于模式数据具有位错误,则检测器产生用于提供给提取器的第一成帧代码检测输出作为用于提供定时的信号。 然而,如果输出与模式数据一致,则检测器产生第二成帧代码检测输出。 参考信号发生器与第二成帧代码检测输出相对应地产生用于提取器的参考信号。
