ATI Radeon HD 5750 brings HDMI bliss to HTPCs for $110

by Ben Drawbaugh posted Oct 14th 2009 at 9:25AM

ATI Radeon HD 5750
We knew that video cards that could bitstream all the latest HD codecs wouldn't always cost $380, but we certainly didn't expect a cheaper alternative in two weeks. Of course price and HDMI audio capabilities aren't the only factors when choosing a video card for your HTPC, so you might want to keep waiting -- you know another few weeks -- for a version that doesn't take up two of your card slots for a fan that is no doubt anything but quiet. Anandtech is predicting you might have to wait another year for the perfect HTPC video card in the way of the 5600 series.

ATI Radeon HD 5870 is the first video card to bitstream TrueHD and DTS-HD

ATI Radeon HD 5870
The good news is that you can finally get both compressed and uncompressed HD audio off a Blu-ray Disc and into your A/V receiver without the need of a dedicated sound card. The bad news is that at $380, the ATI Radeon HD 5870 still costs more than a stand-alone Blu-ray player and that price doesn't even include playback software. That's ok with us though, as we're used to being charged early adopter tax, and now the first video card with this ability is released, it should only be a matter of time before this feature trickles down to video cards we can actually afford.

PS3 Slim bitstreams Dolby TrueHD and DTS-HD MA audio, at last

by Thomas Ricker posted Aug 21st 2009 at 1:53AM Breaking News

Slowly, ever so slowly we're beginning to learn about the internal differences between Sony's new PS3 Slim and its chubby ancestry. We already knew that it supported BraviaLink while talk of "faster gaming" was introduced (suspiciously) yesterday; something that remains very much in doubt until we can confirm. Now we hear that the fatboy gone slim supports Dolby TrueHD and DTS-HD Master Audio bitstream output to your receiver. Hear that audio nerds? Bitstream. See the HDMI chip on previous generations of the PS3 didn't support bitstream output of the new(ish) high def codecs like Dolby TrueHD and DTS-HD MA. As such, the PS3 had to decode it internally before sending it over to your receiver via LPCM. A process that could garble the lossless audio depending on your setup. Even though the vast majority of people will never notice the difference (or even care), PS3 Slim owners can still kick back in smug satisfaction each time the TrueHD or DTS-HD MA indicators light-up on their receivers.

LPCM is not always equal to bitstream

TrueHD and DTS-HD logoThis is an on going debate on certain forums and for good reason. The fundamental question is where should you decode your lossless audio? In DVD players we almost always decoded compressed audio in the A/V receiver, but when it comes to Blu-ray features like Bonus View, there is at least one specific reason to decode in the player.

Auzen X-Fi HomeTheater 7.1 HDMI sound card does bitstream output from your HTPC

by Darren Murph posted Jun 20th 2008 at 11:33AM

Earlier this month, ASUS introduced the "world's first HDMI 1.3a compliant audio / video enhancement combo card." Who knew numero dos was so close behind? Auzentech has just announced its very own HDMI 1.3-native PCIe audio combo card, which is built around Creative's X-Fi processor and enables PC users to easily output 7.1-channel audio with no downsampling. Essentially, the Auzen X-Fi HomeTheater 7.1 "accepts video from either an internal or external connection, mixes it with digital audio, and outputs the combined video and lossless multichannel audio via a single HDMI 1.3 port." Yep, that means Dolby TrueHD and DTS-HD Master Audio codecs are fully supported. The only digs? For one, pricing remains a mystery, but the real kicker is the September release -- talk about a long wait.

Samsung delays fourth gen BD-P1500 Blu-ray player, adds BD-Live

by Richard Lawler posted Apr 23rd 2008 at 2:15PM Breaking News


We can't really see the logic in releasing a Blu-ray player without BD-Live in 2008 -- and neither can Samsung, which just announced its fourth generation BD-P1500 will be BD-Live Ready. The bad news is the May release date announced earlier has slipped to June, and the formerly comfortable $399 MSRP is now a less promising TBA. We're not sure if that "ready" tag means it will be BD-Live enabled out of the gate, however DTS-HD "High resolution" is confirmed on the way in a future firmware update. A slight delay for a significant upgrade in features? We'll allow it.

Update: Samsung let us know the press release was in error, the MSRP will remain at $399.

Poll: Which is better LPCM or Bitstream?

by Ben Drawbaugh posted Apr 11th 2008 at 12:44PM

Next-gen audio formatsFor years we've sent digital audio in the form of a compressed bitstream from our disc player to our audio/video receiver for decoding. So whether we used a Toslink cable or coaxial digital cable, the Dolby Digital or DTS signal wasn't decoded by our player. But today -- thanks to HDMI -- we have the bandwidth to send uncompressed multi-channel audio from the player to the amp without having to resort to six or eight analog RCA cables -- ala the PS3. And with the latest version of HDMI 1.3, we also have the more traditional option of letting our AV/R do the heavy lifting. But of course this begs the question; which is best? On one hand if we decode in the player we lose the ability to use all the bells and whistles we paid for in the latest receiver we bought -- assuming we bought one. But on the other, if we don't decode in the player we lose any sounds from the interactive features or maybe even a secondary audio track that may play along side the main audio. Luckily, some players give you a choice, but the most popular Blu-ray player doesn't, as the PS3 doesn't support bitstreaming TrueHD or DTS-HD (it will bitstream Dolby Digital and DTS though). So assuming you even have a choice, which is better, decoding in the player or in your AV/R.

Pioneer's BDP-LX80 Blu-ray player supports HD audio bitstream output

by Thomas Ricker posted Aug 2nd 2007 at 5:53AM


Pioneer just announced that Blu-ray Disc player with "HD audio bitstream output" they alluded to with the launch of their BDP-LX70. In what appears to be an industry first for BD players, the new BDP-LX80 supports bitstream output of both Dolby TrueHD and DTS-HD high resolution audio output over HDMI 1.3. Sorry, no DTS-HD Master Audio this time. Still, a worthy update from the LX70 assuming your home theater gear is properly matched to decode that signal. Something you'll want to check, and double-check, before dropping the tax inclusive roll of ¥210,000 or about $1,768. We could be wrong, but the move from the LX70 to LX80 appears to be a firmware change only so why all the fuss with a new model Pioneer? If true, then don't be surprised to find a hacked version of the firmware for the LX70 on the Internets soon enough. No word on a global launch -- Japan-only for now with a local release scheduled for October.
