摘要： An interface is realized that can prevent video signals from being copied easily and which uses a luminance/color difference signal transmission scheme with an excellent harmony with a television circuit. In a video transmission using a digital interface, colorimetry information for defining the conversion from the luminance/color difference signal into a primary color signal and video aspect ratio information are transmitted along with the luminance/color difference type video signal. This allows reproduction of video with high quality and high resolution and also realizes a copyright protection which allows only the users authorized by key information to use the content of the video. With this transmission scheme, it is possible to provide a transmitting apparatus, a receiving apparatus and an interface which highly harmonize with a rationalized television-based circuit.

摘要： A high definition display unit which demodulates, decodes, and processes in relation to chroma and displays a television signal in which a PI (picture) signal and an SI (service information) signal are mixed. A changeover switch 13 connected to an image quality adjusting circuit in a video chroma processing circuit 7 is opened or closed according to an on-off signal SI showing the superposed period of both signals detected by a decoder 4. If the above on-off signal SI is on, the changeover switch 13 is opened and the adjustment of image quality is disabled. Therefore, SI display never disappears due to the adjustment of image quality, and the quality of an image can be also adjusted according to an ambient status. Other approaches are also disclosed from preventing image quality adjustment of at least portions of a displayed image containing an information image.

摘要： A display device which displays an image on a cathode-ray tube screen based on video information decoded from a signal-compressed digital broadcast signal. The video information contains fields having a number of scanning lines which may change from field to field, potentially causing vertical jitter in the displayed image. A circuit prevents the vertical jitter by setting a same vertical scanning start position of an electron beam on the screen for all of the fields regardless of the number of scanning lines. The circuit may be a clamp circuit which clamps a vertical ramp waveform; or a control circuit which controls a direct current level of the vertical ramp waveform when the number of scanning lines in a current field is different from a reference number of scanning lines; or an amplitude control circuit which performs feedback control of an amplitude of the vertical ramp waveform.
摘要翻译：一种显示装置，其基于从信号压缩的数字广播信号解码的视频信息，在阴极射线管屏幕上显示图像。视频信息包含具有多个可能从场到场的扫描线的场，可能导致显示图像中的垂直抖动。无论扫描线数量如何，通过为所有场设置与电子束相同的垂直扫描开始位置来防止垂直抖动。该电路可以是夹紧垂直斜坡波形的钳位电路; 或者当当前场中的扫描线数与扫描线的基准数目不同时，控制垂直斜坡波形的直流电平的控制电路; 或者执行垂直斜坡波形的振幅的反馈控制的幅度控制电路。
