Abstract
A scheme for detecting shot boundaries in the compressed video data at high speed and high accuracy. In this shot boundary detection scheme, a Predictive-picture (P picture) change is calculated from a P picture sequence in the input video data which is compressed by an inter-frame/inter-field forward direction prediction coding scheme, according to coded data contained in the P picture sequence, while an Intra-picture (I picture) change is calculated from an I picture sequence in the input video data which is compressed by an intra-frame/intra-field coding scheme, according to coded data contained in the I picture sequence. Then, a shot boundary is detected by evaluating both the P picture change and the I picture change.
