    • In a picture display device suitable for receiving and processing an incoming video signal which comprises horizontally scanned picture information and for displaying pictures which are composed of fields each of which comprises a given number of lines, a scanning section for generating line and field scanning signals for forming the lines and fields, respectively, is adapted to scan the lines in the vertical direction, a number of vertical lines constituting a field and the vertical line frequency being many times higher, at least 200 times, than the horizontal field frequency. A video signal processing section for processing the picture information which is present in the video signal comprises a scan direction transposition circuit for receiving the picture information and for sequentially assigning picture information to elements of the vertically scanned lines.
    • 在适于接收和处理输入视频信号的图像显示装置中,该输入视频信号包括水平扫描的图像信息和用于显示由包括给定行数的场组成的图像;扫描部分,用于产生线和场扫描信号, 形成线和场分别适于扫描垂直方向上的线,构成场的垂直线数,垂直线频率比水平场频多至少200倍。 用于处理存在于视频信号中的图像信息的视频信号处理部分包括用于接收图像信息的扫描方向转置电路,并且用于将图像信息顺序地分配给垂直扫描线的元素。

    • In a system for transmitting and receiving a television signal via a transmission channel having at least a transmitting section and a receiving section, the transmitting section including a sampling circuit for sampling each field of the television signal in accordance with a sampling pattern which is shifted field-sequentially at least in the horizontal direction, the transmitting section further includes a field interleaving circuit for generating a field to be transmitted by interleaving between sampling values of a sampled field of the television signal sampling values of at least one further sampled field of the television signal having mutually different shifted sampling patterns, so that a higher temporal resolution is possible on display of the television signal.
    • 在用于经由至少具有发送部分和接收部分的传输信道发送和接收电视信号的系统中,发送部分包括一个采样电路,用于根据采样模式对电视信号进行采样,采样模式是移位的 至少在水平方向上,发送部分还包括场交错电路,用于通过在电视机的至少一个进一步采样场的电视信号采样值的采样场的采样值之间进行交织来产生要发送的场。 信号具有相互不同的移位采样模式,使得在显示电视信号时可以获得更高的时间分辨率。
