PlayTV allows you to watch, pause and record free-to-air digital television channels using your PS3. You can pause live television, or rewind it if you missed something; record one channel while watching another; and access a complete guide to the coming week's programmes.
If you also have a PSP, then it's easy to take the full service with you, wherever you go; if you are within range of a Wireless Internet connection, you can take advantage of PlayTV's great features from anywhere in the world, using Remote Play for PSP.
Not only can you watch your favourite shows live and in superb quality while you're abroad, you can record channels and watch them back later. In summary, you can do everything with your PSP that you could do if you were sat in front of the TV at home.
Remote Play allows you to take control of your PS3 from your PSP, so the advantages aren't restricted to PlayTV; you can watch movies or listen to music saved on the PS3 system's hard drive and even play games that support the feature.
