DVB-C2 LDPC / BCH
Decoder
DVB-C2 (Digital Video Broadcast – Cable 2nd Generation) is an ETSI
standard of the second generation for digital data transmission via
cable networks. It complements the existing standards DVB-S2 and DVB-T2
for satellite and terrestrial communication and offers a
capacity-approaching coding scheme. The Creonic DVB-C2 IP core
integrates the forward error correction as defined by the standard
(including LDPC and BCH decoder).
Applications
-
Digital Video Broadcasting in cable
networks -
Further applications with highest
demands on forward error correction -
Applications with high signal-to noise
ratios -
Applications with the need for high
code rates (2/3 to 9/10)
