More info on supported audio formats by this first-generation Sony Blu-Ray player from TWICE:
"Blu-ray audio: Sonyâ€™s $1,000 player will deliver Blu-rayâ€™s mandatory codecs â€” Dolby Digital 5.1, DTS 5.1 and six-channel 192khz/ 24-bit uncompressed PCM through the playerâ€™s single-port HDMI 1.1 output and through six analog outputs, the company confirmed. The player, however, doesnâ€™t support Blu-rayâ€™s optional surround codecs, some of which require future HDMI 1.3 outputs not yet ready for production, the company said.
Although some companies have considered modifying the HDMI 1.1 spec to deliver some of the optional codecs to outboard decoders, â€œSony will not go off-standard,â€ said Phil Abram, VP of the home products division.
The optional codecs requiring HDMI 1.3 pipes, according to the HDMI Licensing organization, are compressed to Dolby TruHD and DTS HD Master Audio lossless formats. HDMI Licensing president Leslie Chard said other optional Blu-ray codecs could be transported over todayâ€™s HDMI 1.1 inputs and outputs. They are eight-channel 96khz/24-bit PCM, lossy Dolby Digital Plus and lossy DTS HD.
â€œIt would not be possible in a compliant wayâ€ to transport DTS HD Master and Dolby TruHD over HDMI 1.1â€ and would create â€œinteroperability issuesâ€ if suppliers modified the 1.1 spec on their own, Chard told TWICE. Connecting compliant and noncompliant 1.1 inputs and outputs would yield â€œwhite noiseâ€ instead of surround sound, he said. â€œWeâ€™re not going to authorize that option.â€
The publication of the HDMI 1.3 spec is tentatively set for June, Chard said.
It was unclear whether suppliers could legally license HDMI 1.1 technology and modify it but not use the HDMI logo."
