I'm a little confused how the video streaming will work within Home.
Phil showed off a few examples:
a) playing a video installed on your PS3 on a virtual bravia in your "apartment"
b) having full videos playing in the public area
c) having an auditorium with a streaming video "in hidef" that you can join
Obviously given the public nature of all these video streams it would be possible for 1, 2, 3 or more of your friends or people to "warp" into the room with the video(s) playing.
So how are they going to support this when currently if I go to the playstation PSN online store to download "casino royale" (the trailer that was shown by Phil playing in one of the public spaces) it takes about 20 seconds to navigate to the movie, about 5 seconds for the download to "start", and about 30 minutes for it to download (it being a 1 minute HD preview).
If my video is stored on my PS3 I can see how it could appear in home for me "almost" instantly, but what about for my friends? am I going to blast it to them all individually? how likely is that with upload speeds of about 512kbit typical max in america, and less in some other countries? (The same question applies also to mp3s i want to play in my apartment. But perhaps at 128kbit they are more doable).
What about when sony wants to fill a public space with new game preview movies and movie previews? does entering the space immediately kick off some mega background downloads and we get "buffering" appearing on all the monitors? Will home snarf 10gig of our hard drives to cache video content? we can't even make video happen seamlessly on the web yet (even flash players suck), let alone in hidef, so I'm wondering how they plan to hide all this streaming required for home when people are not all sitting on a 100mbit or gige lan!
