European operators have created the world’s first television roaming system

    Telefónica and Siminn have pioneered the world’s first TV roaming scenario based on an open caching standard.

    The leading Spanish telecommunications company Telefónica and the largest telecommunications operator in Iceland, Siminn, successfully conducted the first practical session of television roaming.

    The two companies were able to demonstrate the possibility of transmitting video programs with local delivery to a subscriber who is on a guest network. To do this, operators have unified their content delivery networks (CDNs) using an open caching standard proposed by the Streaming Video Technology Alliance (SVTA).

    The tests were based on the following scenario. A Siminn subscriber, while in Spain, had to access his television service through the Telefónica network. For this, the Siminn company delegated the rights of local content delivery to Telefónica’s CDN network.

    Testing was carried out in a laboratory environment. At the same time, his goal was to get the opportunity to involve the same scenario for wide use in practical activities in the coming months.

    The Open Caching project promoted by SVTA provides standard interfaces that allow any content provider to improve the quality of their video services. This is achieved by bringing the content provider closer to the end user through the use of CDN networks. This scenario also allows operators to optimize video traffic on their own networks. This is especially true today, as video traffic already accounts for 80% of total traffic and is expected to continue to grow in the coming years.

    “Open caching” will allow ISPs to provide users with improved quality TV services when they access them from outside their own networks. The quality improvement is made possible by closer delivery and higher availability, which will be ensured by using a local operator’s CDN. In addition, both operators will significantly reduce the amount of traffic associated with these scenarios, resulting in improved service efficiency.
