Abstract
A one pass adaptive bit rate control method. Data from a previous video field is used to calculate a quantizer scale factor for use in compressing a current video field. Large changes in compressed data size is used to detect scene changes. When a scene change is detected, a marker is inserted into the compressed data stream in place of the compressed field. An interpolated field is substituted during decompression for the scene change marker.
