E.164 based global identification scheme for IPTV service portability

Currently, the IPTV services are provided through a device, called as set-top box which is dependent on the service providers. This becomes a huge constraint to customers who wants to enjoy their IPTV service more than two places and also becomes a huge loss to service providers who wants to encourage more utilization by their customers. The solution for this problem is providing an IPTV service portability that enables customers to access to their IPTV service anywhere without their own set-top box but with any other service providerpsilas set-top boxes. For this service, several technical issues such as global identification, contents and signal transcoding, CAS/DRM utilization, service security are required to be settled. Among them, the most important issues to support an IPTV portability service is global identification. In this paper, we propose a global identification scheme with E.164 using SIP with IPTV global roaming service scenario.
