On July 3, Heat TV will launch on Sky and Virgin Media, joining Heat's existing multimedia portfolio, including a radio station and Heatworld online portal.
The channel will debut with Hugest Pop Songs on Planet Earth, Heat's new interactive show involving viewers voting on the best pop songs in the world. Voting has already started on Heatworld.com.
Heat will produce a special augmented-reality edition of the magazine to mark the TV channel's launch day, featuring a raft of content related to celebrities such as Louis Walsh and David Walliams accessible via a special mobile app.
Other new programmes on Heat TV will include a celebrity entertainment series, entitled My Showbiz Life, offering an "intimate look" into the lives of some major stars.
Pop Video Analysed, based on a feature in the magazine, will analyse some new and retro pop classics from Heat's "peculiar and unique perspective".
Celebrity biography series Real Stories will also return for a third season, including features on singers Pink, Adele and Nicki Minaj.
Alongside original programming, Heat TV will also offer music videos, breaking celebrity news stories and integration with social networks, such as Twitter.
"People have been asking us for years why Heat doesn't have a TV channel," said Heat magazine editor Lucie Cave.
"Well, it's because we wanted to get it right - and now we have, with an amazing new proposal that combines the best of music, gossip and social media"
Heat TV will be operated by Box TV, the music television join venture between Heat publisher Bauer Media and Channel 4.
Box TV added Heat TV to its music channel portfolio in May this year.
