Abstract :
Finding the designated video shots from the video stream within a short time is a big issue in the multimedia consumer electronic applications. To largely reduce the time needed to access the desired video shots, a new system for retrieving the specific shots was built utilizing the on-line motion detection with the DSP. The specific video shots could be retrieved at a reduced processing time by using the DSP because a series of motion vectors were generated in real time on the DSP using the on-line Y signal image frames. The start and stop frame codes resulting from the retrieval easily pick up only the designated video shots from the video stream. The processing time from the motion detection to the start and stop frame code generation was equivalent to 13 ms per frame.
