TVii on the WII U is a TV service, for watching local TV, the USA has had it basically since the Wii U was released, but the European version has never been activated and it never will, as Nintendo have cancelled plans to bring the service out in Europa, here is a quote from the source:
At Nintendo of Europe, we continue to challenge ourselves to develop a range of entertaining experiences for all to enjoy. Due to the extremely complex nature of localising multiple television services across a diverse range of countries with varied licensing systems, regrettably we have taken the decision not to launch the Nintendo TVii service within the European region. Although on this occasion we did not anticipate such challenges, we will always strive to develop a range of entertaining experiences for all our users to enjoy.
