Speaking at Tokyo Game Show during his keynote, Sony Computer Entertainment president, Kaz Hirai, showed off some new features of the PSP and PS3's remote play functionality. Chief among the features was the option to turn on your PS3 with your PSP.

Sure, if you're already in the room with your PS3 then not having to stand up to switch it on isn't much of a bonus, but if you're out and about and want to take a look at some multimedia content stored at home it's a pretty nifty feature. Users will also be able to put their PS3 to sleep remotely, Hirai confirmed. The feature will roll out in a future PSP firmware update.

Kaz also let fly a handful of other details, saying of remote play:



To demonstrate the use of the PSP as a second screen, Kaz showed F1 doing the honours.

The last sentence of Hirai's quote strikes us as a bit cryptic. Presumably Kaz means you'll be able to load game save data onto the PSP and then pick up where you left off on another machine. If he meant that you'll be able to play PS3 games on the PSP... well, what a wonderful, strange world we'd be living in.

Other news to come out of Kaz's keynote is the delay of Home and confirmation of rumble for the PS3.
