APPLE has unveiled a new TV product which it says will revolutionise our lounge rooms, allowing us to search for TV shows and movies across multiple content providers using just our voice.

The all-new Apple TV is "built from the ground up with a new generation of high-performance hardware", Apple said on Thursday morning.

It uses a Siri Remote and a new tvOs operating system, based on Apple's iOS, enabling millions of iOS developers to create innovative new apps and games specifically for Apple TV.

"There has been so much innovation in entertainment and programming through iOS apps, we want to bring that same excitement to the television," said Eddy Cue, Apple's senior vice president of Internet Software and Services.

"Apps make the TV experience even more compelling for viewers and we think apps represent the future of TV."

The new Siri Remote  simplifies how you select, scroll and navigate through your favourite content while bringing unique interactivity to the new Apple TV by using a glass touch surface that handles both small, accurate movements as well as big, sweeping ones.

Adding touch to Apple TV creates a natural, connected experience, even if the TV screen is on the other side of the room.

Developers can take advantage of the built-in accelerometer and gyroscope, and the touch surface on the Siri Remote to create games and other app experiences that have never been seen on TV before.

With Siri, you can use your voice to search TV shows and movies by title, genre, cast, crew, rating or popularity, making it easy to say things like "Show me New Girl," "Find the best funny movies from the '80s," "Find movies with Jason Bateman" and "Find popular TV shows for kids."

Apple TV will search iTunes and Netflix, displaying all the ways the resulting TV shows and movies can be played. Siri also offers playback control and on-screen navigation, as well as quick access to stock and weather information.*

Apple says the new, more powerful Apple TV features the Apple-designed A8 chip for even better performance so developers can build engaging games and custom content apps for the TV.

tvOS supports key iOS technologies including Metal, for detailed graphics, complex visual effects and Game Center, to play and share games with friends.

Apple has also unveiled a giant iPad with a 12.9 inch screen alongside new iPhones.

Tim Cook opened the event promising "monster" updates as he unveiled the iPad Pro, a 12.9 inch screen tablet.

It is also revealed new iPhones, called the 6s and 6s Plus,at the event, which include a new rose gold option and a new screen technology called 3D Touch
