As promised by Sony late last month, the PlayStation
Store revamp is now here. PlayStation 3 users who check for a network
update will find that firmware version 2.30 is available.
For gamers, the most immediately appreciable improvement in
the new software is support for the redesigned PlayStation Store, which drops
its web browser foundation in favor of a locally viewable but still online
required version. The result of this change is much quicker browsing speeds,
which are now more comparable to Xbox Live Marketplace rather than a slow
website. A video walkthrough of the new store is available on the official PlayStation
Early PS3 owners who installed the update reported that the
store would occasionally fail to load images, instead displaying only a “missing
image” placeholder. Some have been able to fix the problem by clearing the PS3
web browser cache, though various loading errors on the store could be due to
the PlayStation Network’s heavy strain from the masses of updates.
The PlayStation Store accessible via the PC and PSP also
sport a new look, though the changes appear to be cosmetic and do not behave
the same as the PlayStation 3 version.
For high-definition movie enthusiasts, the 2.30 firmware
also brings with it the much anticipated DTS-HD
Master Audio support for the console’s Blu-ray Disc playback feature. Like
PCM and Dolby TrueHD, DTS-HD MA can deliver audio presentation that is bit-for-bit
identical to the original studio master.
“PS3 was designed to enable delivery of new and improved
technologies like DTS-HD Master Audio,” said Teiji Yutaka, SVP of Software
Platform Development at SCE. “So we are delighted to be able to offer this
capability to PS3 users.”
The 2.30 firmware update is now available from the
PlayStation 3 update function, or as a direct
download to PC from PlayStation
quote: Because of the nature of sigma-delta converters, one cannot make a direct comparison between DSD and PCM. An approximation is possible, though, and would place DSD in some aspects comparable to a PCM format that has a bit depth of 20 bits and a sampling frequency of 192 kHz. PCM sampled at 24 bits provides a (theoretical) additional 24 dB of dynamic range. Due to the effects of quantization noise, the usable bandwidth of the SACD format is approximately 100 kHz, which is similar to 192 kHz PCM.
quote: P.S. 99% of people don't care and can't tell a difference between an SACD and an MP3 at 192kbps.
quote: Sure when listening through headphones.
quote: Ps.. Unknown to most, even the best D/A (digital to analogue) converters can only reproduce around 18 to 19 bits of resolutin. So in reality comparing 20 to 24 bits when 5-6 bits are being lost in noise, the difference is negligable. Also SACD's method of using 1 bit at a high sample rate, can give it an effective SNR of up to 120db.. much higher than DVD-A and PCM. This is the reason most audiophiles prefer SACD over DVD-A, even though looking at the specs, DVD-A/PCM seems better.
