Abstract

A method and system (Figs. 34 and lA) in which a section of a previously encoded digital bit stream (Fig. 33A) is replaced with another section of encoded video (Fig. 33D). In order to remove a section of encoded video, it is necessary to determine the beginning and ending points of the encoded video in the digitally encoded bit stream (Fig. 33A). The addresses of the beginning and ending points are calculated by summing the bits consumed by each picture, the number of bits of the sequence header of each picture, the number of bits of each Group of Pictures (GOP) header and all stuff bits. In order to encode the video which is to be inserted in place of the removed video, a process is performed which prevents decoding artifacts from appearing (Fig. 34). This is accomplished by determining a last P-picture before the edit point and using it as a reference frame for frames after the edit point (786). Additionally, a short period of the original video encoded using its original quantizer values is included at the end of the video to be substituted (784).
