Real-Time Logo Insertion Method Based on Partial Recoding Algorithm
Xingdong Wang · Video Engineering · 2010
A fast real-time logo insertion method for MPEG-2 video stream is presented in this paper.This method is based on the previous partial recoding algorithm,including some simplification and improvement for the requirement of real-time use.The existing partial recoding algorithm can be more efficient by reducing the recoding area and simplifying the processing of macroblocks.Comparing to the traditional full-region recoding algorithm,the proposed method gains better video quality and processing efficiency for the use of real-time MPEG-2 logo insertion.
