SCEE product planning manager Kazuhiro Yanase said that while Share Play "doesn't require any super-fast broadband," the company won't disclose recommended upload and download speeds for those looking to share games sessions with friends over PSN. "The internet environment is really different user by user. For example, some users will be using a LAN cable, some users will be using Wi-Fi, sometimes you use the microwave in your house," Yanase told Video Gamer. "It's very difficult for us to guarantee you can use Share Play if you have [a certain] speed."
Today's update also adds the ability to play music from a USB device with support for MP3 and AAC file types. The Masamune update introduces YouTube as an option for gameplay clip uploading as well as home screen themes. We've reached out to Sony to confirm the Share Play restrictions and will update as we learn more.
