Sony Entertainment Network SEN
I linked to the Sony Corporate Blog because they have a nice little breakdown of what SEN can do. The Sony Entertainment Network (SEN) is designed to bring music and video as well as gaming to your home via browser/PC, PS3 or Sony Bravia TV, as well as mobilize your video, gaming and music experience, with your Sony Xperia, PSP or PS Vita. SEN follows an all-screen-approach with a twist: your mobile devices need to be made by Sony in order to use them. No iOS, Mac supported.
