摘要

Provided is a video quality assessment system for digital TV. The video quality assessment system includes a video quality test signal insertion device which inserts a test signal for testing video quality into a predetermined area of a transient effect area (TEA) of each frame of a source video and a video quality measurement device which detects the test signal from a predetermined area of the video signal recovered after reception and outputs the test signal. Preferably, an insertion position of the test signal is one line or two or more lines of the TEA area which are located in a lower end portion of the video, and the test signal is configured with multi-bursts including a large number of frequencies which are in a range of DC to ½ of a sampling frequency.
