After securing a UK broadcast licence for the channel in April, MTV has now announced that a high-definition simulcast of the Nickelodeon channel will become available on the digital satellite platform on October 5.
Nickelodeon HD will broadcast HD versions of popular animated programmes, such as Fanboy & Chum Chum and The Penguins Of Madagascar, as well as live action shows, including iCarly, Victorious, Big Time Rush and The Troop.
The channel, which in the UK is a joint venture between Sky and MTV, will be available to all Sky+ HD customers taking the Kids pack as part of their subscription package.
In response to the Nickelodeon HD launch, MTVNHD will no longer broadcast a block of Nickelodeon programming every weekend and instead focus on music-related content.
The channel will expand its library of music programming to more than 1,000 hours by the end of 2011, including "original and acquired live performances, documentaries and world-class events".
MTVNI president Bob Bakish said: "With the successful launch and expansion of MTVNHD in less than two years, we are committed to further investment in the high definition medium across our industry leading brands.
"These new HD services will create stronger bonds with our kid, youth and adult audiences, as well as provide innovative new products to cable and satellite operators as demand continues to grow.
"HD will help fuel our long-term creative and business growth as we continue to leverage our global scale and expertise to develop, package and deliver quality content across all platforms."
Sky's chief operating officer Mike Darcey added: "We're delighted to announce the addition of Nickelodeon HD to Sky+ HD, the UK's leading high definition service.
"Sky remains committed to delivering customers the best HD service available, and this means continuing to work with high-quality content partners to launch outstanding channels right across the schedule. With the best of free and pay TV now in HD, there’s never been a better time to embrace HD."
Nickelodeon HD follows the recent launch of MTV's Comedy Central HD on Sky and Virgin Media, broadcasting HD versions of Two And A Half Men, 30 Rock and South Park.
