IPTV services have rapidly developed in the last few years with the progresses of IP networks technology. Such real time application requires the demand of quality of services but the IP networks of today provides poor support of QoS. To solve the problem of the impact of jitter of the IP network, a video buffer control strategy combined with dynamic adjusting of the playback rate and selected discard certain frames according to the buffer fullness is presented. This strategy keeps the buffer fullness in the stable zone and minimums the quality degradation. The implementation of this strategy achieves the goal and proves that it can greatly improve the quality of IPTV.
