- Hierarchical layers + <constant>DTV-ISDBT-LAYER*</constant> parameters ISDB-T channels can be coded hierarchically. As opposed to DVB-T in ISDB-T hierarchical layers can be decoded simultaneously. For that reason a ISDB-T demodulator has 3 viterbi and 3 reed-solomon-decoders. ISDB-T has 3 hierarchical layers which each can use a part of the available segments. The total number of segments over all layers has to 13 in ISDB-T. + There are 3 parameter sets, for Layers A, B and C.
