Abstract
A television receiving system for converting a video signal of one line standard to a video signal of another line standard. A field delay circuit is provided which separates the video signal of the one line standard into a high frequency and low frequency portion. The low frequency portion of the signal is processed to have a delay during one field different from the delay of a subsequent field. Independent processing means for the high frequency portion of the separated signal is provided. The processed high frequency and low frequency signals are combined to provide a video signal for converting to a different line standard. By processing the high frequency and low frequency portions of the video signal differently, a savings in hardware components is realized without material degradation in performance.
