It couldn’t be easier to get the latest exciting downloads onto your PS3.
PlayStation Store is an online shop where you can download (as a purchase or for free) products such as full games, additional game items, videos, trailers, interviews and other goodies. Using and visiting PlayStation Store is free.
Once in PlayStation Store you can browse content and download it to your PS3. To download content simply click on its image, banner or listing to start the process.
Once downloading has started you have the option for the download to Perform in Background. This is part of the download management, which adds your chosen downloaded content to a queue while continuing to browse PlayStation Store.
Video content is available for download in a variety of formats including SD (Standard Definition - ideal if you don't own an HD-ready TV) and High Definition at either 720p or 1080p resolution.

Selected content that can be purchased is added to your shopping Cart. Once you have finished viewing products that you add to your shopping Cart, you can proceed to the checkout and download. If you've insufficient funds available to complete the purchase, you'll be prompted to add funds to your wallet. A wide variety of credit and debit cards can be used to add funds. Items that you download can be re-download up to a maximum of five times by visiting your purchase history.
Free content such as game demos and Blu-ray movie trailers are also available to download. All the content you choose to download is saved on to the hard disc drive of your PS3, and you can access it there as many times as you want.
It is now possible to purchase or download free of charge content for your PSP directly from PlayStation Store. Through the new PSP Games section, full games, demos and game add-ons are now easily downloadable from your PS3 to your PSP. All content within this section is playable on your PSP, while some of it will also be compatible with your PS3.
Don't worry if you exit the Store while content is downloading. It'll continue to download in the background unless you play a Blu-ray Disc, a game, a DVD or switch the PS3 system off. As long as you're signed in to PlayStation Network your downloads will continue until they are complete. Even if you switched the machine off in the middle of downloading, it'll resume when you next Sign In to PlayStation Network.
