An image inspection method may include sampling a continuous digital image signal by dividing the signal by less than or equal to 20 msec; extracting a high-frequency component from the sampled signal; and detecting an error occurred in an image on the basis of the extracted high-frequency component.
A first video characteristic value is determined from a video/audio signal. The first video characteristic value is embedded in an audio portion of the video/audio signal and the video/audio signal is transmitted from a transmission source to a transmission destination. At the destination, the first video characteristic value is recovered and the received video/audio signal is used to determine a second video characteristic value. The recovered first video characteristic value is used to veri…
