Paper Abstract

In this paper, we work on the problem of inserting logo into part of a previously compressed video sequence while transcoding it to a video stream with lower rate. In most of the transcoding architecture, it has been widely accepted to reuse the motion information extracted from the original incoming bit stream. For our transcoding and logo insertion process, we preserve the same motion information as the incoming video stream for the parts that were unaffected by logo, and propose an efficient algorithm to code logo areas. We first find the proper range of pictures that might be affected by logo insertions, analyze logo-affected parts of those pictures, and perform corresponding algorithms depending on the picture types. In addition, we develop a method to achieve better bit allocation during logo insertion. The efficiency of our algorithm is demonstrated by simulation.
