Information hiding for H.264 in video stream switching application

By embedding some information into different resolutions of videos and combining the video segments together, the paper proposed a H.264 information hiding algorithm in video stream switching application. Detailed embedding course carries out in the movement vector after H.264 compression, and the embedding needn´t to be operated while the video being transmitted, making the real-time performance possibility, which meets well with the aim of the information hiding in stream switching application. Experiment shows that this method increases little bit rate and suitable for the stream switching application.
