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

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


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?

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.

Sony launches four high-end Blu-ray recorders


It may be raining on AT&T's parade today but the sun is out and blasting Japan with plenty of Blu-ray.

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


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.
