5.1.12. FRL Character Block and Super Block Mapping

An FRL Super Block contains four FRL Character Blocks. FRL Character Blocks transport one or more FRL packets.

Each Character Block contains up to 502 FRL characters transporting FRL packets and eight FRL characters carrying Reed-Solomon parity data.

Each FRL Super Block is preceded by a group of three or four Start Super Blocks (SSB) or a group of three or four Scrambler Reset (SR) characters. SSB and SR characters are comma characters used by a receiver for character alignment.
