HD DVD and Blu-ray Disc standards currently limit their maximum number of audio channels to eight. However Dolby Digital Plus is an enhanced coding system based on the AC-3 codec. It offers increased bitrates (up to 6.144 Mbit/s), support for more audio channels (up to 13.1), improved coding techniques to reduce compression artifacts, and backward compatibility with existing AC-3 hardware.
DTS-HD Master Audio - Previously known as DTS++ and DTS-HD, DTS-HD Master Audio supports a virtually unlimited number of surround sound channels, can downmix to 5.1- and two-channel, and can deliver audio quality at bit rates extending from DTS Digital Surround up to lossless. Although technically superior over its Dolby counterpart, DTS-HD Master Audio is selected only as an optional surround sound format for Blu-ray and HD-DVD. DTS-HD Master Audio and Dolby TrueHD are the only technologies that deliver lossless surround sound for these new disc formats, ensuring the highest quality audio performance available in the new standards. (n.b. DTS Coherent Acoustics coding system has been selected as mandatory audio technology for both the Blu-ray Disc (BD) and High Definition Digital Versatile Disc (HD-DVD)
Why are they limiting it to 8 when we can have up to 13.1
