The Network Media Player (coming soon to PS TV and PS Vita) can be used to access media servers over a network. The Network Media Player can be used to view photos and stream music and videos from a media server located on your home network. You can also copy photos, music and video files from the media server to your system.
Interestingly enough, the US Blog post doesn't mention this.
