摘要：
In this paper we propose a fast logo insertion algorithm for MPEG compressed video. In order to achieve this, we employ compressed data domain logo insertion with an in-loop re-quantization process. We also adaptively use the MV 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.
