Bandwidth is the issue for no TRUE HD / DTS MA over Tos / Coax. There is no HDCP with Tos / Coax - just HDMI and DVI.
Not true that Bandwith is an issue with TOSLINK.
The communication with the newest IBM mainframes (Z196) uses the TOSLINK fiber cables for FICON communications between DASD and other mainframes in a SYSPLEX is
FICON link data rate = 100 MB/sec (100MBps)http://www-01.ibm.com/software/htp/t...s03/tgs03l.pdf
The Audio Codec is DTS-HD High Resolution.
The Audio Channels (sound scheme) can appear as 5.1 (most typical) or 7.1 (unusual).
Audio Fidelity data: the DTS-HD specification indicates it is 24 bits deep, and can be recorded at 48 kHz (typical for HD DVD) or 96 kHz (would probably be used for Blu-ray, but there aren't any).
Audio Bit Rate values can go as high as 6.144 Mbps for encoded data, but might be either 1.5, 4.5, or 6.144 Mbps, depending on the bandwidth that the studio decides to allocate to this type of audio track. Those HD DVDs that supported DTS-HD invariably used 1.5 Mbps bitrateshttp://www.tomsguide.com/us/high-def...ew-1088-4.html
100MBps is a heck of a lot higher then 6.144Mbps
100 MB=100 Mbytes
Bits and Bytes
A bit is a single character of data (a 0 or a 1). A byte is eight characters of data. Therefore, eight bits make a byte. Your computer processes information in a series of eight bits, or, one byte.
Consumer optical/coaxial digital adhere to and are limited to the S/PDIF consumer specification.
It is not the cable that is the problem with 7.1 sound ,it is the implementation limited to the S/PDIF consumer specification
