    • PURPOSE: A method and apparatus automatically detect a TV signal format by using a video encoder in order to allow a proper encoding of a signal having a sequential scanning, an interlaced scanning, a specific pixel and a vertical line resolution, and automatically detect a HDTV format. CONSTITUTION: A method for determining a video signal format has successive frames and at least one reference sequence assumed by successive pixel sample field, determines a video signal format having a clock pulse corresponding to the pixel sample field, and provides a clock signal of the video signal. The method detects a reference sequence at a specific line of the video signal, starts a counting of the clock pulse in response to a detection of the reference sequence, detects a reference sequence at the next line of the specific line, and determines a video signal format according to the reference count signal. If the reference sequence is detected at the next line, the count arrives at the reference count value. Thereby, a video encoder automatically detect a TV signal format in order to allow a proper encoding of a signal.
    • 目的:一种方法和装置通过使用视频编码器自动检测TV信号格式,以便对具有顺序扫描,隔行扫描,特定像素和垂直线分辨率的信号进行适当编码,并自动检测HDTV 格式。 构成:用于确定视频信号格式的方法具有连续帧和由连续像素采样场假设的至少一个参考序列,确定具有对应于像素采样场的时钟脉冲的视频信号格式,并提供视频的时钟信号 信号。 该方法检测在视频信号的特定行处的参考序列,响应于参考序列的检测开始对时钟脉冲的计数,检测特定行的下一行的参考序列,并确定视频信号 根据参考计数信号进行格式化。 如果在下一行检测到参考序列,则计数到达参考计数值。 因此,视频编码器自动检测TV信号格式,以便对信号进行适当的编码。
