Previously, buyers had one-time access to videos purchased through the PlayStation Network, which effectively prevented the copying, redownloading, or transfer of Video Unlimited content. Sony's new policy, discovered by Shacknews, adds support for persistent cloud libraries, along with the ability to redownload content across supported devices like the PlayStation 3, PS Vita, and PSP.
The change in policy applies to new purchases as well as content bought prior to Sony's recent Terms of Service update. "If you purchase a copy, the video or TV show download will be available infinitely and can be transferred to other enabled devices," Sony's Video Unlimited website now states.
