Of course it is possible that some +very sophisticated devices won't need certain parameters to tune. + +The information given here should help application writers to know how +to handle ISDB-T and ISDB-Tsb hardware using the Linux Digital TV API. + +The details given here about ISDB-T and ISDB-Tsb are just enough to +basically show the dependencies between the needed parameter values, but +surely some information is left out. For more detailed information see +the following documents: + +ARIB STD-B31 - "Transmission System for Digital Terrestrial Television +Broadcasting" and + +ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial Television +Broadcasting". + +In order to understand the ISDB specific parameters, one has to have +some knowledge the channel structure in ISDB-T and ISDB-Tsb. I.e. it has +to be known to the reader that an ISDB-T channel consists of 13 +segments, that it can have up to 3 layer sharing those segments, and +things like that. + +The following parameters are valid for ISDB-T: + +- :ref:`DTV_API_VERSION <DTV-API-VERSION>` + +- :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` + +- :ref:`DTV_TUNE <DTV-TUNE>` + +- :ref:`DTV_CLEAR <DTV-CLEAR>` + +- :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` + +- :ref:`DTV_BANDWIDTH_HZ <DTV-BANDWIDTH-HZ>` + +- :ref:`DTV_INVERSION <DTV-INVERSION>` + +- :ref:`DTV_GUARD_INTERVAL <DTV-GUARD-INTERVAL>` + +- :ref:`DTV_TRANSMISSION_MODE <DTV-TRANSMISSION-MODE>` + +- :ref:`DTV_ISDBT_LAYER_ENABLED <DTV-ISDBT-LAYER-ENABLED>` + +- :ref:`DTV_ISDBT_PARTIAL_RECEPTION <DTV-ISDBT-PARTIAL-RECEPTION>` + +- :ref:`DTV_ISDBT_SOUND_BROADCASTING <DTV-ISDBT-SOUND-BROADCASTING>` + +- :ref:`DTV_ISDBT_SB_SUBCHANNEL_ID <DTV-ISDBT-SB-SUBCHANNEL-ID>` + +- :ref:`DTV_ISDBT_SB_SEGMENT_IDX <DTV-ISDBT-SB-SEGMENT-IDX>` + +- :ref:`DTV_ISDBT_SB_SEGMENT_COUNT <DTV-ISDBT-SB-SEGMENT-COUNT>` + +- :ref:`DTV_ISDBT_LAYERA_FEC <DTV-ISDBT-LAYER-FEC>` + +- :ref:`DTV_ISDBT_LAYERA_MODULATION <DTV-ISDBT-LAYER-MODULATION>` + +- :ref:`DTV_ISDBT_LAYERA_SEGMENT_COUNT <DTV-ISDBT-LAYER-SEGMENT-COUNT>` + +- :ref:`DTV_ISDBT_LAYERA_TIME_INTERLEAVING <DTV-ISDBT-LAYER-TIME-INTERLEAVING>` + +- :ref:`DTV_ISDBT_LAYERB_FEC <DTV-ISDBT-LAYER-FEC>` + +- :ref:`DTV_ISDBT_LAYERB_MODULATION <DTV-ISDBT-LAYER-MODULATION>` + +- :ref:`DTV_ISDBT_LAYERB_SEGMENT_COUNT <DTV-ISDBT-LAYER-SEGMENT-COUNT>` + +- :ref:`DTV_ISDBT_LAYERB_TIME_INTERLEAVING <DTV-ISDBT-LAYER-TIME-INTERLEAVING>` + +- :ref:`DTV_ISDBT_LAYERC_FEC <DTV-ISDBT-LAYER-FEC>` + +- :ref:`DTV_ISDBT_LAYERC_MODULATION <DTV-ISDBT-LAYER-MODULATION>` + +- :ref:`DTV_ISDBT_LAYERC_SEGMENT_COUNT <DTV-ISDBT-LAYER-SEGMENT-COUNT>` + +- :ref:`DTV_ISDBT_LAYERC_TIME_INTERLEAVING <DTV-ISDBT-LAYER-TIME-INTERLEAVING>` + +In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>` +are also valid. + + +.. _atsc-params: + +ATSC delivery system +==================== + +The following parameters are valid for ATSC: + +- :ref:`DTV_API_VERSION <DTV-API-VERSION>` + +- :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` + +- :ref:`DTV_TUNE <DTV-TUNE>` + +- :ref:`DTV_CLEAR <DTV-CLEAR>` + +- :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` + +- :ref:`DTV_MODULATION <DTV-MODULATION>` + +- :ref:`DTV_BANDWIDTH_HZ <DTV-BANDWIDTH-HZ>` + +In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>` +are also valid. + + +.. _atscmh-params: + +ATSC-MH delivery system +======================= + +The following parameters are valid for ATSC-MH: + +- :ref:`DTV_API_VERSION <DTV-API-VERSION>` + +- :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` + +- :ref:`DTV_TUNE <DTV-TUNE>` + +- :ref:`DTV_CLEAR <DTV-CLEAR>` + +- :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` + +- :ref:`DTV_BANDWIDTH_HZ <DTV-BANDWIDTH-HZ>` + +- :ref:`DTV_ATSCMH_FIC_VER <DTV-ATSCMH-FIC-VER>` + +- :ref:`DTV_ATSCMH_PARADE_ID <DTV-ATSCMH-PARADE-ID>` + +- :ref:`DTV_ATSCMH_NOG <DTV-ATSCMH-NOG>` + +- :ref:`DTV_ATSCMH_TNOG <DTV-ATSCMH-TNOG>` + +- :ref:`DTV_ATSCMH_SGN <DTV-ATSCMH-SGN>` + +- :ref:`DTV_ATSCMH_PRC <DTV-ATSCMH-PRC>` + +- :ref:`DTV_ATSCMH_RS_FRAME_MODE <DTV-ATSCMH-RS-FRAME-MODE>` + +- :ref:`DTV_ATSCMH_RS_FRAME_ENSEMBLE <DTV-ATSCMH-RS-FRAME-ENSEMBLE>` + +- :ref:`DTV_ATSCMH_RS_CODE_MODE_PRI <DTV-ATSCMH-RS-CODE-MODE-PRI>` + +- :ref:`DTV_ATSCMH_RS_CODE_MODE_SEC <DTV-ATSCMH-RS-CODE-MODE-SEC>` + +- :ref:`DTV_ATSCMH_SCCC_BLOCK_MODE <DTV-ATSCMH-SCCC-BLOCK-MODE>` + +- :ref:`DTV_ATSCMH_SCCC_CODE_MODE_A <DTV-ATSCMH-SCCC-CODE-MODE-A>` + +- :ref:`DTV_ATSCMH_SCCC_CODE_MODE_B <DTV-ATSCMH-SCCC-CODE-MODE-B>` + +- :ref:`DTV_ATSCMH_SCCC_CODE_MODE_C <DTV-ATSCMH-SCCC-CODE-MODE-C>` + +- :ref:`DTV_ATSCMH_SCCC_CODE_MODE_D <DTV-ATSCMH-SCCC-CODE-MODE-D>` + +In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>` +are also valid. + + +.. _dtmb-params: + +DTMB delivery system +==================== + +The following parameters are valid for DTMB: + +- :ref:`DTV_API_VERSION <DTV-API-VERSION>` + +- :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` + +- :ref:`DTV_TUNE <DTV-TUNE>` + +- :ref:`DTV_CLEAR <DTV-CLEAR>` + +- :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` + +- :ref:`DTV_MODULATION <DTV-MODULATION>` + +- :ref:`DTV_BANDWIDTH_HZ <DTV-BANDWIDTH-HZ>` + +- :ref:`DTV_INVERSION <DTV-INVERSION>` + +- :ref:`DTV_INNER_FEC <DTV-INNER-FEC>` + +- :ref:`DTV_GUARD_INTERVAL <DTV-GUARD-INTERVAL>` + +- :ref:`DTV_TRANSMISSION_MODE <DTV-TRANSMISSION-MODE>` + +- :ref:`DTV_INTERLEAVING <DTV-INTERLEAVING>` + +- :ref:`DTV_LNA <DTV-LNA>` + +In addition, the :ref:`DTV QoS statistics <frontend-stat-properties>` +are also valid. |
