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 DVB-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 read this document 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. + +Parameters used by ISDB-T and ISDB-Tsb. + +Existing parameters +=================== + +a) DTV_FREQUENCY + +Central frequency of the channel. + +For ISDB-T the channels are usally transmitted with an offset of 143kHz. E.g. a +valid frequncy could be 474143 kHz. The stepping is bound to the bandwidth of +the channel which is 6MHz. + +As in ISDB-Tsb the channel consists of only one or three segments the +frequency step is 429kHz, 3*429 respectively. As for ISDB-T the +central frequency of the channel is expected. + +b) DTV_BANDWIDTH_HZ (optional) + +Possible values: + +For ISDB-T it should be always 6000000Hz (6MHz) +For ISDB-Tsb it can vary depending on the number of connected segments + +Note: Hardware specific values might be given here, but standard +applications should not bother to set a value to this field as +standard demods are ignoring it anyway. + +Bandwidth in ISDB-T is fixed (6MHz) or can be easily derived from +other parameters (DTV_ISDBT_SB_SEGMENT_IDX, +DTV_ISDBT_SB_SEGMENT_COUNT). + +c) DTV_DELIVERY_SYSTEM + +Possible values: SYS_ISDBT + +d) DTV_TRANSMISSION_MODE + +ISDB-T supports three carrier/symbol-size: 8K, 4K, 2K. It is called +'mode' in the standard: Mode 1 is 2K, mode 2 is 4K, mode 3 is 8K + +Possible values: TRANSMISSION_MODE_2K, TRANSMISSION_MODE_8K, + TRANSMISSION_MODE_AUTO, TRANSMISSION_MODE_4K + +If DTV_TRANSMISSION_MODE is set the TRANSMISSION_MODE_AUTO the +hardware will try to find the correct FFT-size (if capable) and will +use TMCC to fill in the missing parameters. + +TRANSMISSION_MODE_4K is added at the same time as the other new parameters. + +e) DTV_GUARD_INTERVAL + +Possible values: GUARD_INTERVAL_1_32, GUARD_INTERVAL_1_16, GUARD_INTERVAL_1_8, + GUARD_INTERVAL_1_4, GUARD_INTERVAL_AUTO + +If DTV_GUARD_INTERVAL is set the GUARD_INTERVAL_AUTO the hardware will +try to find the correct guard interval (if capable) and will use TMCC to fill +in the missing parameters. + +New parameters +============== + +1. DTV_ISDBT_PARTIAL_RECEPTION (1b) + +If DTV_ISDBT_SOUND_BROADCASTING is '0' this bit-field represents whether +the channel is in partial reception mode or not. + +If '1' DTV_ISDBT_LAYERA_* values are assigned to the center segment and +DTV_ISDBT_LAYERA_SEGMENT_COUNT has to be '1'. + +If in addition DTV_ISDBT_SOUND_BROADCASTING is '1' +DTV_ISDBT_PARTIAL_RECEPTION represents whether this ISDB-Tsb channel +is consisting of one segment and layer or three segments and two layers. + +Possible values: 0, 1, -1 (AUTO) + +2. DTV_ISDBT_SOUND_BROADCASTING (1b) + +This field represents whether the other DTV_ISDBT_*-parameters are +referring to an ISDB-T and an ISDB-Tsb channel. (See also +DTV_ISDBT_PARTIAL_RECEPTION). + +Possible values: 0, 1, -1 (AUTO) + +3. DTV_ISDBT_SB_SUBCHANNEL_ID + +This field only applies if DTV_ISDBT_SOUND_BROADCASTING is '1'. + +(Note of the author: This might not be the correct description of the + SUBCHANNEL-ID in all details, but it is my understanding of the technical + background needed to program a device) + +An ISDB-Tsb channel (1 or 3 segments) can be broadcasted alone or in a +set of connected ISDB-Tsb channels. In this set of channels every +channel can be received independently. The number of connected +ISDB-Tsb segment can vary, e.g. depending on the frequency spectrum +bandwidth available. + +Example: Assume 8 ISDB-Tsb connected segments are broadcasted. The +broadcaster has several possibilities to put those channels in the +air: Assuming a normal 13-segment ISDB-T spectrum he can align the 8 +segments from position 1-8 to 5-13 or anything in between. + +The underlying layer of segments are subchannels: each segment is +consisting of several subchannels with a predefined IDs. A sub-channel +is used to help the demodulator to synchronize on the channel. + +An ISDB-T channel is always centered over all sub-channels. As for +the example above, in ISDB-Tsb it is no longer as simple as that. + +The DTV_ISDBT_SB_SUBCHANNEL_ID parameter is used to give the +sub-channel ID of the segment to be demodulated. + +Possible values: 0 .. 41, -1 (AUTO) + +4. DTV_ISDBT_SB_SEGMENT_IDX + +This field only applies if DTV_ISDBT_SOUND_BROADCASTING is '1'. + +DTV_ISDBT_SB_SEGMENT_IDX gives the index of the segment to be +demodulated for an ISDB-Tsb channel where several of them are +transmitted in the connected manner. + +Possible values: 0 .. DTV_ISDBT_SB_SEGMENT_COUNT-1 + +Note: This value cannot be determined by an automatic channel search. + +5. DTV_ISDBT_SB_SEGMENT_COUNT + +This field only applies if DTV_ISDBT_SOUND_BROADCASTING is '1'. + +DTV_ISDBT_SB_SEGMENT_COUNT gives the total count of connected ISDB-Tsb +channels. + +Possible values: 1 .. 13 + +Note: This value cannot be determined by an automatic channel search. + +6. Hierarchical layers + +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. + +6.1 DTV_ISDBT_LAYER_ENABLED (3b) + +Hierarchical reception in ISDB-T is achieved by enabling or disabling +layers in the decoding process. Setting all bits of +DTV_ISDBT_LAYER_ENABLED to '1' forces all layers (if applicable) to be +demodulated. This is the default. + +If the channel is in the partial reception mode +(DTV_ISDBT_PARTIAL_RECEPTION=1) the central segment can be decoded +independently of the other 12 segments. In that mode layer A has to +have a SEGMENT_COUNT of 1. + +In ISDB-Tsb only layer A is used, it can be 1 or 3 in ISDB-Tsb +according to DTV_ISDBT_PARTIAL_RECEPTION.
