Requirements of seamless TV service among multi-domains

Abstract

This paper reviewed brief transition of TV services and new challenge from existing TV service domains. We reviewed different service roles for each TV service domains, as well common direction and goals. Recently, new types of TV service are emerging, for example, IPTV from network providers, more competitive portal TV from content providers and advanced TV terminal from TV manufacturers. Also, we suggest a seamless TV service scenario between TV domain and mobile domain, which demands several service requirements to provide such kind of seamless TV service in current vertical TV environments. From this example, we focused on existing relevant standardization requirements from W3C and ITU-T. As well, further requirements are considered for harmonization of current standards.
