Abstract

This paper proposes a dynamic GOP structure selection method to provide seamless video streaming for vertical handoff in the heterogeneous wireless network. The proposed method dynamically changes the interval of Ipictures by using the received signal strength indication (RSSI) and the pilot strength (Ec/Io) in order to reduce error propagation due to packet losses. Thus, with the proposed method, the client can always receive the I-picture right after vertical handoff. Experimental results show that the proposed method can significantly reduce the video quality degradation caused by vertical handoff in the real-time video encoding applications.
