Of course it is possible that some 100very sophisticated devices won't need certain parameters to tune. 101 102The information given here should help application writers to know how 103to handle ISDB-T and ISDB-Tsb hardware using the Linux Digital TV API. 104 105The details given here about ISDB-T and ISDB-Tsb are just enough to 106basically show the dependencies between the needed parameter values, but 107surely some information is left out. For more detailed information see 108the following documents: 109 110ARIB STD-B31 - "Transmission System for Digital Terrestrial Television 111Broadcasting" and 112 113ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial Television 114Broadcasting". 115 116In order to understand the ISDB specific parameters, one has to have 117some knowledge the channel structure in ISDB-T and ISDB-Tsb. I.e. it has 118to be known to the reader that an ISDB-T channel consists of 13 119segments, that it can have up to 3 layer sharing those segments, and 120things like that. 121 122The following parameters are valid for ISDB-T: 123 124- :ref:`DTV_API_VERSION <DTV-API-VERSION>` 125 126- :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` 127 128- :ref:`DTV_TUNE <DTV-TUNE>` 129 130- :ref:`DTV_CLEAR <DTV-CLEAR>` 131 132- :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` 133 134- :ref:`DTV_BANDWIDTH_HZ <DTV-BANDWIDTH-HZ>` 135 136- :ref:`DTV_INVERSION <DTV-INVERSION>` 137 138- :ref:`DTV_GUARD_INTERVAL <DTV-GUARD-INTERVAL>` 139 140- :ref:`DTV_TRANSMISSION_MODE <DTV-TRANSMISSION-MODE>` 141 142- :ref:`DTV_ISDBT_LAYER_ENABLED <DTV-ISDBT-LAYER-ENABLED>` 143 144- :ref:`DTV_ISDBT_PARTIAL_RECEPTION <DTV-ISDBT-PARTIAL-RECEPTION>` 145 146- :ref:`DTV_ISDBT_SOUND_BROADCASTING <DTV-ISDBT-SOUND-BROADCASTING>` 147 148- :ref:`DTV_ISDBT_SB_SUBCHANNEL_ID <DTV-ISDBT-SB-SUBCHANNEL-ID>` 149 150- :ref:`DTV_ISDBT_SB_SEGMENT_IDX <DTV-ISDBT-SB-SEGMENT-IDX>` 151 152- :ref:`DTV_ISDBT_SB_SEGMENT_COUNT <DTV-ISDBT-SB-SEGMENT-COUNT>` 153 154- :ref:`DTV_ISDBT_LAYERA_FEC <DTV-ISDBT-LAYER-FEC>` 155 156- :ref:`DTV_ISDBT_LAYERA_MODULATION <DTV-ISDBT-LAYER-MODULATION>` 157 158- :ref:`DTV_ISDBT_LAYERA_SEGMENT_COUNT <DTV-ISDBT-LAYER-SEGMENT-COUNT>` 159 160- :ref:`DTV_ISDBT_LAYERA_TIME_INTERLEAVING <DTV-ISDBT-LAYER-TIME-INTERLEAVING>` 161 162- :ref:`DTV_ISDBT_LAYERB_FEC <DTV-ISDBT-LAYER-FEC>` 163 164- :ref:`DTV_ISDBT_LAYERB_MODULATION <DTV-ISDBT-LAYER-MODULATION>` 165 166- :ref:`DTV_ISDBT_LAYERB_SEGMENT_COUNT <DTV-ISDBT-LAYER-SEGMENT-COUNT>` 167 168- :ref:`DTV_ISDBT_LAYERB_TIME_INTERLEAVING <DTV-ISDBT-LAYER-TIME-INTERLEAVING>` 169 170- :ref:`DTV_ISDBT_LAYERC_FEC <DTV-ISDBT-LAYER-FEC>` 171 172- :ref:`DTV_ISDBT_LAYERC_MODULATION <DTV-ISDBT-LAYER-MODULATION>` 173 174- :ref:`DTV_ISDBT_LAYERC_SEGMENT_COUNT <DTV-ISDBT-LAYER-SEGMENT-COUNT>` 175 176- :ref:`DTV_ISDBT_LAYERC_TIME_INTERLEAVING <DTV-ISDBT-LAYER-TIME-INTERLEAVING>` 177 178In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>` 179are also valid. 180 181 182.. _atsc-params: 183 184ATSC delivery system 185==================== 186 187The following parameters are valid for ATSC: 188 189- :ref:`DTV_API_VERSION <DTV-API-VERSION>` 190 191- :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` 192 193- :ref:`DTV_TUNE <DTV-TUNE>` 194 195- :ref:`DTV_CLEAR <DTV-CLEAR>` 196 197- :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` 198 199- :ref:`DTV_MODULATION <DTV-MODULATION>` 200 201- :ref:`DTV_BANDWIDTH_HZ <DTV-BANDWIDTH-HZ>` 202 203In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>` 204are also valid. 205 206 207.. _atscmh-params: 208 209ATSC-MH delivery system 210======================= 211 212The following parameters are valid for ATSC-MH: 213 214- :ref:`DTV_API_VERSION <DTV-API-VERSION>` 215 216- :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` 217 218- :ref:`DTV_TUNE <DTV-TUNE>` 219 220- :ref:`DTV_CLEAR <DTV-CLEAR>` 221 222- :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` 223 224- :ref:`DTV_BANDWIDTH_HZ <DTV-BANDWIDTH-HZ>` 225 226- :ref:`DTV_ATSCMH_FIC_VER <DTV-ATSCMH-FIC-VER>` 227 228- :ref:`DTV_ATSCMH_PARADE_ID <DTV-ATSCMH-PARADE-ID>` 229 230- :ref:`DTV_ATSCMH_NOG <DTV-ATSCMH-NOG>` 231 232- :ref:`DTV_ATSCMH_TNOG <DTV-ATSCMH-TNOG>` 233 234- :ref:`DTV_ATSCMH_SGN <DTV-ATSCMH-SGN>` 235 236- :ref:`DTV_ATSCMH_PRC <DTV-ATSCMH-PRC>` 237 238- :ref:`DTV_ATSCMH_RS_FRAME_MODE <DTV-ATSCMH-RS-FRAME-MODE>` 239 240- :ref:`DTV_ATSCMH_RS_FRAME_ENSEMBLE <DTV-ATSCMH-RS-FRAME-ENSEMBLE>` 241 242- :ref:`DTV_ATSCMH_RS_CODE_MODE_PRI <DTV-ATSCMH-RS-CODE-MODE-PRI>` 243 244- :ref:`DTV_ATSCMH_RS_CODE_MODE_SEC <DTV-ATSCMH-RS-CODE-MODE-SEC>` 245 246- :ref:`DTV_ATSCMH_SCCC_BLOCK_MODE <DTV-ATSCMH-SCCC-BLOCK-MODE>` 247 248- :ref:`DTV_ATSCMH_SCCC_CODE_MODE_A <DTV-ATSCMH-SCCC-CODE-MODE-A>` 249 250- :ref:`DTV_ATSCMH_SCCC_CODE_MODE_B <DTV-ATSCMH-SCCC-CODE-MODE-B>` 251 252- :ref:`DTV_ATSCMH_SCCC_CODE_MODE_C <DTV-ATSCMH-SCCC-CODE-MODE-C>` 253 254- :ref:`DTV_ATSCMH_SCCC_CODE_MODE_D <DTV-ATSCMH-SCCC-CODE-MODE-D>` 255 256In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>` 257are also valid. 258 259 260.. _dtmb-params: 261 262DTMB delivery system 263==================== 264 265The following parameters are valid for DTMB: 266 267- :ref:`DTV_API_VERSION <DTV-API-VERSION>` 268 269- :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` 270 271- :ref:`DTV_TUNE <DTV-TUNE>` 272 273- :ref:`DTV_CLEAR <DTV-CLEAR>` 274 275- :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` 276 277- :ref:`DTV_MODULATION <DTV-MODULATION>` 278 279- :ref:`DTV_BANDWIDTH_HZ <DTV-BANDWIDTH-HZ>` 280 281- :ref:`DTV_INVERSION <DTV-INVERSION>` 282 283- :ref:`DTV_INNER_FEC <DTV-INNER-FEC>` 284 285- :ref:`DTV_GUARD_INTERVAL <DTV-GUARD-INTERVAL>` 286 287- :ref:`DTV_TRANSMISSION_MODE <DTV-TRANSMISSION-MODE>` 288 289- :ref:`DTV_INTERLEAVING <DTV-INTERLEAVING>` 290 291- :ref:`DTV_LNA <DTV-LNA>` 292 293In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>` 294are also valid. 295
