Re: DVB-T DVB-S DVB-C

DVB-S:
-modulation method: QPSK
-error coding scheme: convolutional + Reed-Solomon

DVB-S2:
-modulation methods: QPSK, 8PSK, 16 APSK and 32APSK
-error coding scheme: BCH + LDPC

For other DVBs:
1. Go to www.etsi.org
2. Click on Services & Products
3. Click on DOWNLOAD NOW!
4. Type '"dvb" in "Search for" field.
5. As a result, you will get access to more than 100 documents (standards) in connection to DVB standard.
6. You will have to register before you download any of these documents (this is not big problem at all).
