An industry body has begun full-time test broadcasts for 4K ultra high-definition broadcasting.

Channel 4K, operated by Next Generation Television and Broadcasting Promotion Forum, or NexTV-F, went live at 1 p.m. Monday. The free-to-view channel will air content provided by member TV stations, including live music, travel and sports programs, initially for six hours or so a day, the organization said.

Viewers need a 4K television, tuner and antenna, and must apply to the operator for access to the channel.

NexTV-F, set up in May 2013 to promote 4K broadcasting, has 62 corporate members, comprising mainly TV stations, electronics makers, ad agencies and trading houses.

The government aims to launch commercial 4K broadcasting in 2016.
