Q. Do I need v1.3 HDMI to hear the new Dolby TrueHD and DTS
Master HD audio content on HD-DVD or Blu-ray players?

No. The Dolby TrueHD, Dolby Digital Plus, and DTS-HD Master
Audio can be decoded by the playback device into multi-channel
Pulse Code Modulation (PCM) digital audio streams, which is an | audio format standard that can be sent over any version of
HDMI. In fact, all versions of HDMI can support up to 8
channels of PCM audio at 192kHz, 24 bits per sample.

To do this, consumers should ensure that their playback device
(such as HD-DVD or Blu-ray player) is capable of decoding
these new lossless Dolby & DTS audio formats into the PCM
format on the HDMI output, and that the audio device (such as | an A/V receiver) is capable of receiving multi-channel PCM
audio over the HDMI inputs. Consult your user manual/product | specification sheet to determine whether your device supports
such PCM capabilities (we believe that nearly all HD-DVD and
Blu-ray players will, but users should confirm this). Devices that
support HDMI v1.3 and higher may also offer the option to
transport the high definition audio formats as a compressed,
encoded stream over HDMI so that the decoding function can be
performed by the A/V receiver (whereas the above transport | method has the playback device performing the decoding).
