Hello Guys,
thank you all for your answers. I am just pointing a quote from our dear friend Venkat's post
"HD Audio such as TrueHD, DTS HD etc are stored in compressed form and cannot be transmitted as such. A high end DVD player will, thus, extract such sound from the disc, decode it, and mix it into muti channel PCM. This is then transmitted through HDMI 1.1 or higher connections. You have to ensure that your receiver not only has an HDMI input but should also have the ability to handle the multichannel PCM signal. "
Hence taking all the suggestions it can be summarized that the a/v receiver must have
1) Multi channel PCM handling capacity
2) It must have HDMI 1.3 according to Ashish and 1.1 or higher according to Venkat.
Here below what I found about different versions of HDMI
Basic Timeline for HDMI:
Version 1.0 - December 2002.
Arrived! - HDMI 1.0 spec was first released at the end of 2002.
Version 1.1 - May 2004.
Support for DVD Audio
Version 1.2 - August 2005.
Support for One Bit Audio format, such as SuperAudio CD's DSD (Direct Stream Digital)
Adds use of the (now standard) HDMI Type A connector for PC sources and displays with full support for PC video formats
Ability for PC sources to use their native RGB color-space while retaining the option to support the YCbCr CE color space
Requirement for HDMI 1.2 and later displays to support future low-voltage (i.e., AC-coupled) sources, such as those based on PCI Express I/O technology
Version 1.3 - June 2006 - The latest revision!
Higher speed - Although all previous versions of HDMI have had more than enough bandwidth to support all current HDTV formats, HDMI 1.3 increases its single-link bandwidth to 340 MHz (10.2 Gbps) to support the demands of future HD display devices, such as higher resolutions, Deep Color and high frame rates. In addition, built into the HDMI 1.3 specification is the technical foundation that will let future versions of HDMI reach significantly higher speeds
Deeper Color - HDMI 1.3 supports 30-bit, 36-bit and 48-bit (RGB or YCbCr) color depths, up from the 24-bit depths in previous versions of the HDMI specification, for stunning rendering of over one billion colors in unprecedented detail.
Broader color space - HDMI 1.3 adds support for xvYCC color standard, which removes current color space limitations and enables the display of any color viewable by the human eye.
New mini connector - With small portable devices such as HD camcorders and still cameras demanding seamless connectivity to HDTVs, HDMI 1.3 offers a new, smaller form factor connector option.
Lip Sync - Because consumer electronics devices are using increasingly complex digital signal processing to enhance the clarity and detail of the content, synchronization of video and audio in user devices has become a greater challenge and could potentially require complex end-user adjustments. HDMI 1.3 incorporates automatic audio synching capabilities that allows devices to perform this synchronization automatically with total accuracy.
New HD lossless audio formats - In addition to HDMIs current ability to support high-bandwidth uncompressed digital audio and all currently-available compressed formats (such as Dolby Digital and DTS), HDMI 1.3 adds additional support for new lossless compressed digital audio formats Dolby TrueHD and DTS-HD Master Audio.
Hence we can see HDMI 1.3 was launched in June 2006 and we can fairly assume that all the latest equipment is fitted with HDMI 1.3
My problem is I need to find out if the Sony HT-DDW5000 does have this capability to play dolby true hd and dts master from a connected bluray player.Since it is fairly new I am assuming it has HDMI 1.3 and its specs says
Decoding Format
Dolby Digital/DTS Yes / Yes
Dolby Prologic Yes
Dolby Prologic II Yes
Dolby Prologic IIx Yes
Dolby Digital EX Yes
Digital Cinema Sound Yes
Digital Cinema Auto Calibration (D.C.A.C) Yes
96k/24Bit PCM Yes
Dolby Dual Mono Yes
Video Features
A/V SYNC Yes (fixed)
HDMI Repeater No (Switcher)
HDMI Quality - 1080p Yes
HDMI Quality - 1080/24p Yes
Is this information conclusive enough to say if it has multichannel LPCM and HDMI 1.3.
