The quality of sound and image in video transmission and reception systems depends on several factors, including the sampling rate used in the system. In this paper, the effect of sampling rate on the quality of the received video was studied by simulating and implementing a digital transmission and reception system for sending video using the GNU-Radio platform. The study was applied to two types of video: the first is a video with different colors and the other is a video with a single luminance modified from First video. The results showed that the sampling rates in the period [1MHz-4MHz] give the best quality of the received video in terms of the sound and image being uninterrupted and synchronized for both types, in addition to that the best delay time for receiving the video took 2 sec and 3 sec for video with different colors and video with single luminance, respectively, at a sampling rate of 2MHz.
