Puncturing values for DVB-S code rates:
1/2 code rate = Puncture Size = 2, Puncture Pattern = 0b11
2/3 code rate = Puncture Size = 4, Puncture Pattern = 0b1101
3/4 code rate = Puncture Size = 6, Puncture Pattern = 0b110110
5/6 code rate = Puncture Size = 10, Puncture Pattern = 0b1101100110
7/8 code rate = Puncture Size = 14, Puncture Pattern = 0b11010101100110
A test Transport Stream for the example flow graph
(8 Msyms/s and 7/8 code rate) is available here:
http://www.w6rz.net/advdvbs78.ts
It is 170,950,844 bytes.
This stream can also be used at:
14 Msyms/s 1/2 code rate
10.5 MSyms/s 2/3 code rate
9.333333 MSyms/s 3/4 code rate
8.4 Msyms/s 5/6 code rate
The equation for calculating the correct Transport Stream bit-rate is:
TS bit-rate = symbol rate * 2 * code rate * (188 / 204)
