Recently, the demand on IPTV services has been greatly increasing. For effectively supporting IPTV services via wireless network of limited resource, various techniques have been developed. In this paper, in order to efficiently provide the VoD(Video on Demand) service to a large number of users of wireless IPTV, we propose a scheme improving the existing batching scheme. The proposed scheme properly...
Today, mobile IPTV provides various multimedia services. Therefore, extensive researches on providing service continuity in the mobile IPTV environment are being conducted. Here reducing the user waiting time under the restriction of limited bandwidth is an important design issue in the video on-demand multicast service. In this paper we propose a scheme reducing the waiting time of a user wanting...
Recently, as mobile IPTV has emerged in the area of mobile multimedia streaming, various researches on ensuring service continuity between fixed and wireless networks have been undertaken. VoD transmission in mobile IPTV is a challenging task since it causes long user waiting time and requires a large number of channels. In this paper, we propose an approach appropriately selecting a broadcasting...
The rapid advancement of mobile communication technologies recently has led to the advent of mobile IPTV service. For a variety of multimedia services, a process of session setup using SIP (session initiation protocol) is required. However, high frame error rate (FER) of typical wireless network causes failure and delay in session setup. In this paper we propose a new scheme minimizing the session...
Mobile IPTV is one of the hot applications capitalizing recently advanced wireless communication technologies. This paper proposes a new vertical handover scheme based on the prediction of mobility of mobile node. In contrast with the existing schemes, the proposed approach considers the movement velocity and direction of the MN, and Received Signal Strength (RSS) for accurate prediction of the MN's...
