At the heart of PS3 is the Cell Broadband Engine, one of the most advanced computer processors in the world, that enables massive floating point calculation, and Blu-ray Disc (BD) drive, providing a High Definition (1080p) next-generation gaming and movie experience in the home, as well as up to 50 GB of data capacity.System software update (v4.10) added a feature that enabled you to hear your own voice through the Wireless Stereo Headset when playing multiplayer modes. This type of audio feedback is known as “sidetone.” Based on your comments, system software update (v4.20) will improve sidetone audio performance by giving you the option to select one out of five levels for microphone audio, or turn the feature off completely. For those of you who use the Wireless Stereo Headset to watch Blu-ray or DVD movies on your PS3, this system software update will also enable virtual surround sound functionality, giving you a superior audio experience.
This update will also allow you to set the amount of time that the system will wait before turning itself off automatically for [Video/TV/Music/Photo] and for [Game/Other Features].
Additionally, saved data management has been improved. You will now be able to select multiple saved data items and delete or copy them as a group.
