    Abstract: A LCD display device for receiving encrypted video data and for decrypting the video data such that a signal is not provided “in the clear” before receipt by the display device. The video data is encrypted within a row of video and decrypted at the display. Alternatively the rows are encrypted by altering the time sequence of display of each row.

    Abstract: A display device for receiving encrypted or scramble video data and for decrypting or descrambling the video data such that a signal is not provided “in the clear”. The video data is stored in a memory array in an encrypted form and read out from the memory array using a decryption key. The encrypted data is then read out from the memory elements in accordance with known methods.

    Abstract: Each line of a wide aspect ratio television signal is divided into a main panel component and two augmentation panel components for transmission or storage. The two augmentation panels are transmitted in a multiplex analog format on the same channel. They are transmitted adjacent to one another so that additional signals such as audio signals will occupy the same time slots regardless of the respective widths of the panels. (The sum of the panel widths remains constant even in pan and scan operations). Weighted transition augmentation samples effect a transition from the last redundant pixel of one augmentation panel component to the first redundant pixel of the second augmentation panel component.

    Abstract translation: 宽纵横比电视信号的每一行分为主面板组件和两个用于传输或存储的增强面板组件。 两个增强面板在同一通道上以多路模拟格式传输。 它们彼此相邻地传输,使得诸如音频信号的附加信号将占据相同的时隙,而与面板的相应宽度无关。 (即使在平移和扫描操作中,面板宽度的总和也保持不变)。 加权过渡增强样本影响从一个增强面板组件的最后冗余像素到第二增强面板组件的第一冗余像素的转变。

    Abstract: An adaptive comb filter employs vertical and horizontal edge detectors to selectively activate a vertical high-pass filter and a horizontal band-pass filter during the occurrence of vertical and horizontal edges in a received television signal, for use in the chrominance/luminance separation process. Artifacts such as "hanging dots" and "crawling dots", inherent in prior art comb filter circuits during the occurrence of vertical and horizontal edges in the composite television signal, are greatly reduced in the process.
