Abstract :
The efficiency of a rate control mechanism depends on knowledge of the video complexity. The high number of different occurrences that can exist in a given video sequence, makes it very difficult to encode at a constant bit rate while maintaining the picture quality constant. This paper presents a “feed forward bit rate control” that improves the perceptual quality of a video sequence. The algorithm also produces indexing information that allows detecting and classifying shot scenes
