Abstract: Home media wireless network (HMWN) is getting more and more popular issue in the future world. Nowadays, most of video streaming algorithm use extra bandwidth to keep high-video quality. Furthermore, to guarantee quality of video streaming when error occur the retransmission and selection drops method should be present. We present a video stream algorithm in this paper that can make usage of bandwidth more efficient and also can be adaptive with error modules in wireless environment. The receiver decides a scheme in the end of frame and feedback to sender immediately before sender start encode next frame. For the home media and algorithm using, we put MPEG-4 to use which is the most popular video codec method in these days. A novel video stream algorithm was proposed in this paper that can make usage of bandwidth more efficient and also can be adaptive with error modules on HMWN.
