While, from the specifications of the new Apple TV, the supported file format is H.264 video with stereo audio in .m4v, .mp4, and .mov file formats. Besides, the iTunes can not support AC3 5.1 files well either. So, how to make full use of your output 1080p H.264 video with AC3 5.1 sound?

Here there’s the solution to it.
First，with an iPad 2 or iPad 3, you can stream video to Apple TV with AC3 5.1 (Dolby Digital) sound via Airplay.
Then, since the new Apple TV is not able to decode 5.1 surround sound to stereo by itself, if you want to play AC3 5.1 (Dolby Digital surround) audio you will need an AV receiver. Applet TV (including 2nd-gen and 3nd-gen) does not decode the surround audio itself, it will pass through the audio to AV receiver for decoding. If you do not have the AV receiver and connect Apple TV directly to your HD TV with HDMI, then there will be only video without sound while playing surround sound movie. But Apple TV itself just works ok with movie of stereo sound.
