摘要

The present invention relates to a vertical delay reproduction apparatus and a digital delay television system, and more particularly, to a digital television system in which a video signal of a television broadcast signal is delayed by a predetermined time period in a digital television so that signal data included in a vertical blanking period of the broadcast signal can be reproduced, Lt; / RTI Accordingly, the present invention is characterized in that it comprises function command input means (10, 12) for setting a function command for reproducing the signal data of the vertical blanking period according to the video signal of the television broadcast, A second memory means (16) for memorizing the vertical / horizontal synchronizing signal extracted from the video signal, a second memory means (16) for storing the vertical / horizontal synchronizing signal extracted from the video signal, Vertical / horizontal synchronizing extraction means (18, 20, 22) for extracting a vertical / horizontal synchronizing signal by separating a synchronizing signal from the video data through the first memory means (16) Vertical detecting means for generating vertical detecting data and counting data of a scanning period according to a result of comparing the vertical / horizontal synchronizing signals extracted by the vertical / horizontal synchronizing extracting means (18.20.22) (10, 12) Horizontal synchronizing signals from the vertical / horizontal synchronizing extracting means (18, 20, 22) to the second memory means (16) by receiving a function command of screen reproduction for signal data of vertical blanking period from the vertical / Address designation of the image memory 4 so that the video data is delayed by 1/2 screen based on the vertical detection data detected as a result of supplying as the reference data to the vertical detection means and the counting data of the scanning period, And control means (32) for performing reading control.
