Sony extended the functionality of both the PS3 and PSP at Germany's Games Convention on Wednesday including a personal video recorder for PS3 and a satellite navigation accessory and messaging service for PSP.

In an effort to further lure in customers, Sony will sell a separate device in Europe that allows user to record live television to the PS3 and wirelessly transfer videos to PSP starting in early 2008.

The device, called PlayTV, is said to help boost sales of both the PS3 and PSP and was rumored earlier this month.
When asked if PlayTV would be coming to North America, a Sony representative told us, "We have no announcements at this time regarding DVR/PVR capabilities for PS3 in North America."

In addition to PVR functionality, Sony also announced Go Explore, a satellite navigation device, and Go Messenger, a voice, video, and chat service, for PSP. Go Explore will support GPS and retail for a €100 and €150 (US$135-$200). Go Messenger will be made possible via a firmware update supporting VoIP (voice over Internet Protocol).

Both services will be available starting in Europe in early 2008.
