They are based on digital processing technology and use various digital methods to process the interlaced, low-field rate video data, including the de-interlacing and field rate conversion.
目前市场上的大多数各种电视机都是基于数字处理技术使用包括去隔行，帧频转换等方法来处理隔行的低帧频的视频数据。
FIG. 3 schematically illustrates an interlaced to progressive scan converter which receives a field-based input signal and generates a progressive scan frame-based output signal.
图3示意性地示出了隔行到逐行扫描变换器，其接收基于场的输入信号并且生成基于逐行扫描帧的输出信号。
