Abstract :
We propose a fast logo insertion algorithm for MPEG compressed video. We employ compressed data domain logo insertion with an in-loop re-quantization process. We also adaptively use the MV (motion vector) and coding information of the input MPEG stream according to logo and non-logo regions. Experiments have shown that much faster and higher quality logo insertion is obtained compared with baseband domain insertion.
