    • An apparatus for displaying on a monitor screen of a computer either a color television picture or a black and white television picture at a frame repetition rate sufficient to show smooth motion in the displayed television picture. The apparatus digitizes an analog television signal to assemble an entire frame of digital video words in a video frame memory. After assembling the frame of digital video words, the apparatus communicates that fact to the computer, and then, responsive to a signal from the computer, transfers the entire frame of the digital video words from the video frame memory to the computer over the computer's processing bus.

    • A composite video input signal is delayed by a delay element and the delayed composite signal is applied to luminance and chrominance inputs of a picture processor for received signals of an NTSC format. For received signals of a PAL format, the delayed composite signal is applied only to the luminance input of the picture processor and the chrominance component of the received signal is transcoded to the NTSC format and applied, without passing through the composite signal delay element, to the chrominance input of the picture processor. The delay of the delay element for the composite video signal is selected to be equal to the transcoding delay whereby luminance and chrominance components of received signals of either NTSC or PAL format are delay compensated. Advantageously, the delay applied to the luminance component is constant and of the same value for signals of either format and so there is no need for switching of delay elements in the luminance path when changing from one format to the other and so undesirable switching artifacts (e.g., DC offset or transient effects) are avoided.
    • 复合视频输入信号被延迟元件延迟,并且延迟的复合信号被施加到用于NTSC格式的接收信号的图像处理器的亮度和色度输入。 对于PAL格式的接收信号,延迟的复合信号仅被施加到图像处理器的亮度输入,并且接收信号的色度分量被转码为NTSC格式,并且在不经过复合信号延迟元件的情况下被施加到 图像处理器的色度输入。 选择复合视频信号的延迟元件的延迟等于代码转换延迟,由此NTSC或PAL格式的接收信号的亮度和色度分量被延迟补偿。 有利地,施加到亮度分量的延迟对于任何格式的信号是恒定的且具有相同的值,因此当从一种格式改变到另一种格式时,不需要在亮度路径中切换延迟元件,并且因此不期望的切换伪影( 例如,DC偏移或瞬态效应)。

    • An automatic on-screen color signal converting circuit is disclosed, which includes a color signal level detecting part (30), an inverting part (40), and combining/switching part (70), wherein the color signal level detecting part (30) detects the level of the video color signal from the input color difference signal and luminance signal and the inverting part (40) inverts the output signal of the color signal level detecting part (30) to combine them with an on-screen signal blanking signal outputted from an OSD generating part (60). Therefore, the cathode ray tube driving circuit (20) is provided with an OSD color signal which is complementary to that of the video signal and the on-screen signal can be always clearly distinguished from the video signal during their simultaneous display and also automatically converted according to changing of the video signals.

    • A multi-standard color field sequence detector includes an analog and a digital processor section, wherein the analog processor section receives a reference video input and provides the signals necessary to drive the digital processor section. A correlator control circuit counts an exact number of 13.5 MHz reference clock cycles, and then supplies a start signal to a burst correlator circuit, which takes samples of a plurality of cycles of burst and correlates the results to determine the polarity of the burst samples. If they are of a first polarity, a count value of corresponding polarity is supplied. If they are of the opposite polarity, a count value of the corresponding opposite polarity is supplied. The sequence of the polarities of the final counts are detected to identify the color field 1 for the standard being used.

Further, in the case of displaying them, by a deflecting means, the vertical amplitude can be made smaller than at the normal time and the vertical picture position can be set in a proper position. Thereby, a television video signal and teletext signal in which the horizontal amplitude and vertical amplitude are set to be, for example, 1/2 those at the normal time can be simultaneously displayed on the picture tube.

    • A widescreen television picture is sampled at a higher sampling rate so as to fit all of the information in the current 52.5 .mu.s active video line time. A selection signal is also incorporated with the widescreen picture signal, allowing non-widescreen television receivers to display a contiguous portion of the widescreen picture without geometric distortion. The widescreen television signal is transmitted either in MAC or widescreen NTSC format, and is received by a decoder. The decoder allows the entire widescreen picture to be displayed on a widescreen receiver, and makes use of the selection signal to display the selected portion of the picture on a standard receiver without geometric distortion. In another embodiment, a decoder allows television signals having the standard aspect ratio to be displayed on receivers having widescreen aspect ratios without geometric distortion.
