  Abstract/
Summary
Third generation mobile communication systems offer many advanced types of multimedia services, as video streaming, video telephony and video conference. Transcoding is adopted to deliver video content to a broad range of end users with different preferences and bandwidth constraints. Temporal transcoding is one of the solutions to reduce the overall bit rate by dropping some frames of the video sequence. We propose a temporal transcoding architecture with a new frame skipping policy allowing real-time communication. Simulation results show that our temporal transcoding achieves a better performance than a quality one, and the proposed frame skipping strategy is able to strongly reduce the computation time of the transcoding process.
