Those of you, waiting for the next PS3 firmware update, ver. 2.30, which includes the revamped PLAYSTATION Store, may now see how the new user interface will look in a video demo featuring Grace Chen. The system software update will also add DTS-HD Master Audio output for Blu-ray videos, which means the high-definition visuals of Blu-ray will now be matched with the highest quality audio for the ultimate movie-watching experience on PS3. The technology delivers audio at the incredibly high rate of 24.5 mega-bits per second (Mbps) on Blu-ray disc, which is significantly higher than standard DVDs. DTS-HD Master Audio also offers 7.1 audio channels at 96k sampling frequency/24 bit depths. The firmware update will add DTS-HD High Resolution Audio as well, which is a similar output technology that requires less disc space.
