I am a new to Reed-solomon. Until recent,I am required to implement Reed-Solomon code on FPGAs. This will be used in our DVD project. However, I have some questions puzzling me greatly. In DVD error correction coding ,should RS(208,192,17) and RS(182,172,11) be shortened or puntured Reed-Solomon codes. I have no way to differentiate the two. Meanwhile, I have great eagerness to comminicate and discuss with others about ECC especially Reed-Solomon codes. My email is [email protected]

Regards!

Is CIRC also used on DVDs.

Regarding the inverse transform equation for p(x), the equation is correct for non-binary fields ${\displaystyle \textstyle v_{i}={\frac {1}{n}}q(\alpha ^{n-i})}$, but for binary fields, the equation should be ${\displaystyle \textstyle v_{i}=q(\alpha ^{n-i})}$,

The issue depends if the field is a a non-binary field, such a a field modulo (929) as used in the examples versus a binary based field GF(2^n) where addition is effectively xor. As a simple way to explain this, for a non-binary field: ${\displaystyle \sum _{i=1}^{n}1=n}$ but for a binary field where n is an odd number ${\displaystyle \sum _{i=1}^{n}1=1}$ .

Rcgldr given you're a big player on the RS page would you have any concerns? -TimeOfDei

TimeOfDei - It's not clear to me what change(s) you are referring to and if the edit(s) in question were already reverted. Rcgldr (talk) 03:27, 14 August 2025 (UTC)[reply]

The article fails to explain what a RS code is. I have a code, but is it a RS code? What is it that defines this code? Some properties are mentioned but that does not define it. Moritzgedig (talk) 15:52, 3 August 2025 (UTC)[reply]

Moritzgedig The article explains both of the encoding methods, "original view" and "BCH view" that are called Reed Solomon. What other information would you want included to define the code beyond how it's encoded? Rcgldr (talk) 03:29, 14 August 2025 (UTC)[reply]
