    • In a motion detector operative on a composite video signal comprising chrominance component signals as well as a luminance component signal, the chrominance component signals are suppressed with a filter 212 that removes only diagonal high frequencies in the spatial-frequency domain. These diagonal high frequencies in the spatial-frequency domain include the chrominance signal components of the composite video signal if it is in accordance with an appropriate standard - for example, that employed by broadcasters in the United States of America, or other countries. Motion detection is improved by reason of including more of the spatial high-frequency components.
    • 在包括色度分量信号和亮度分量信号的复合视频信号上运动的运动检测器中,利用仅去除空间 - 频域中的对角线高频的滤波器212来抑制色度分量信号。 空间频域中的这些对角高频包括复合视频信号的色度信号分量,如果它符合适当的标准,例如美国或其他国家的广播机构使用的标准。 由于包括更多的空间高频分量,运动检测得到改进。

    • Apparatus and a method is disclosed for encoding, transmitting and decoding of one or two auxiliary or control signals on a phase alternating carrier. The phase alternating carrier is generated such that, in a given frame, it is in-phase on one scan line, and out-of-phase on the next scan line relative to the conventional chroma carrier. The (I and Q) chroma information is modulated on the chroma carrier in a conventional form to generate a chroma signal. The phase alternating carrier is modulated with one or two auxiliary signals in a similar fashion. The encoded phase alternating carrier is then added to the modulated chroma carrier (chroma signal), and processed in the chroma channel for recording on a magnetic tape. A decoder or playback apparatus processes the chroma channel to decode the two modulated carriers. The modulated chroma carrier (chroma signal) is decoded in a conventional demodulator to recover the chroma (I and Q) information. The encoded phase alternating carrier is decoded to recover the original auxiliary signals. The auxiliary signals may be digital audio signals or motion signals indicative of motion in the scenes.
    • 公开了用于在相位交替载波上编码,发送和解码一个或两个辅助或控制信号的装置和方法。 产生相位交变载波,使得在给定帧中,它在一条扫描线上同相,而在相对于传统色度载波的下一扫描线上是异相的。 (I和Q)色度信息以常规形式在色度载体上调制以产生色度信号。 以相似的方式用一个或两个辅助信号调制相位交变载波。 然后将经编码的相位交替载波加到调制的色度载波(色度信号)上,并在色度通道中进行处理以在磁带上进行记录。 解码器或重放装置处理色度通道以对两个调制载波进行解码。 调制色度载波(色度信号)在常规解调器中进行解码,以恢复色度(I和Q)信息。 编码相位交替载波被解码以恢复原始辅助信号。 辅助信号可以是表示场景中的运动的数字音频信号或运动信号。
