    Anyone notice that on the iphones 6 specs page, apple lists that facetime supports h.265? Wonder if this is a sign of things to come for ATV?

    That is HUGE- a great find. So now there are 2 new moves by Apple implying an :apple:TV4 is coming soon: 60fps (which current :apple:TVs can't play "as is" and now a reference to h.265 being in play within the new iPhones).

    It should be noted however that h.265 is only listed for "FaceTime over cellular" but not under supported video formats. So I don't think it will play h.265 video but it's still a step in the right direction and indicates the hardware and ios can do it.

    This just means they are bruteforcing it, on the powerful A8 CPU, to minimize cellular data usage.

    But for general video, they aren't going to allow it, due to how battery intensive brute forcing it is.

    Everyone is moving to H.265 for 4K. I'm 99% sure we'll see at least H.265 support on the next apple tv.

    I just hope they keep the bitrate the same (or higher) to allow for better quality, instead of compressing even further and getting the same quality for their itunes tv/movies.

    You would think they would upgrade QT Player to be able to playback h.265 first. Right now it can't. Bleeding edge VLC can.

    As well as MPC-HC, XBMC, ect.

    It's obvious that Apple wants higher quality for example for AirPlay.

    ----------

    QuickTime Player requires hardware, which supports the decoding.

    H.265 requires only 1/2 of the bitrate, compared to H.264. 4K has 4x more pixels than 1080p. So the required bitrate for H.265 4K-material is at least 2 times higher than the bitrate for H.264 1080p.

    Well, that isn't necessary. VLC can support it on my mid 2010 mbp which has no hardware (ie. gpu if thats what you're claiming) specifically designed to decoding h.265.

    Not quite. Best case scenario (in the specs) H.265 can do the same quality as H.264 at half the bitrate, but the encoder (even x265) is not there yet, not even close really. My point about hoping apple keeps the bitrate the same or higher on 1080p H.265, is because their 1080p H.264 are bitstarved and poor quality. If they are just going to use H.265 to drop the bitrate further on their current offerings that would be a disappointment as the quality would not improve at all.

    I'd rather have "double" the quality at the same bitrate, rather than the same quality at half the file size. They aren't in the same ballpark of Blu-ray right now, I'd like to see that change.

    We talk about ATV4, not about your 2010 MBP.

    I know, I was just pointing out that before its avail on an atv4 you will likely first see QTPlayer.app for computers updated to decode h.265. No need to get testy.

    Battery life isn't however an issue for a set top box.

    Battery life no, but total power dissipation is. Devices with small mass have to worry about being able to handle the heat they generate. Forcing the general CPU into high load for an extended period of time can cause heat build up.
