what does the DSS stand for?

Recently I am studing the TIDSP. I find DSS is very common in the MCBSP
program. I want to know the exact meaning of the DSS. Originally I
think it is a module in the DSP/BIOS configuration,but I can't find the
help in the Code Composer Studio.If anyone know the answer,please tell
me.Many thanks!

Can you precisely tell on studying about what, did you come across DSS? I
assume that you are trying to do some work on audio/video coding using
DSP/BIOS. If my assumption is right, the DSS you are looking for stands
for Digital Satellite System. It is a MPEG satellite standard
(properitery) used in North America. Am I answering your question?

thank you very much. You are quite right.I have been studying the
TIDSP.I want to impliment the blind equalizer based on the Constant
Modulus Alogrithm with the TMS320C5410.Now I.m studying the DSB/BIOS
application.The DSS is found with many books about the introduction to
the  DSP/BIOS program.Maybe you're right,I think so.

If you are going to code DSS using DSP/BIOS, please keep in mind that DSS
is a propreitary belonging to DIRECTV. You may have to use separate pipes
for DSS reception and transmission. 

DSS is very much similar to DVB, but you cannot find as many documentation
about it - the same propreitary problem. DSS also uses QPSK like DVB, but
with a smaller packet size, and so their receivers are not completely
compatible. One more similarity is that both these scheme use Vitrebi and
Reed Solomon, but with different code rates. 

So, why can't you try DVB instead of DSS? The DVB standard is open and I
am sure you can find more theoritical material on DVB than DSS.

This is just a personal connotation.

My guess is that DSS in your context is "digital speech standard".
BTW, it took Google 0.19 secs to find it...unfortunately it took me longer
( a few secs ) to type the search into google.

It's a secret kept by the CIA. Revealing it would compromise my health and 
possibly lead
to instant death....or was it instant coffee? ...can't really remember....
