Cloud streaming service Gaikai will allow the streaming of a select number of PS3 games on the PS4 from the start of 2014.
Announcing the news at its E3 press conference, Sony said that the service wouldn't be available straight away at the console's launch, but would arrive at a later date.
The service will go live in the US first, and offer a limited range of PS3 games. Vita streaming will also be offered later next year.
Sony also said it would eventually deliver console quality across a range of devices”.
Sony forked out $380 million for Gaikai last year, and the cloud streaming service is expected to eventually play an integral role in how the PS4 operates.
