USER MANUAL

#1 ISDB-T parameters:
If a file is open with the TMCC file format, the StreamXpress will display the modulation parameters
contains in the file. Note that the “use TMCC Info” tick box needs to be checked to use these
parameters for transmission.
#2 CH:
The StreamXpress allows modulating to any agile RF channel using the Channel frequency field.
For ISDB-T the channel plan is already known and the user can select a “standard” RF channel for
playout. There are 2 types of RF channels available in the StreamXpress: Channel 1 to 62 represent
RF broadcast channel over the air. C31 to C62 represent the channel plan for ISDB over cable.
#3 Frequency:
The StreamXpress allows modulating on a 6MHz or 8MHz bandwidth. Note that 6MHz bandwidth is
prevalent for ISDB-T.
#4 Use TMCC Info:
If the file opened is a TMCC file and contains ISDB-T modulation parameters, this tick box will
appear. If checked, the modulation parameters will be derived from the TMCC file and will overwrite
the parameters sets in Params.
#5 Params:
Select this to change the ISDB-T modulation parameters
The ISDB-T modulation parameters are organized in 4 sections:
1-MPEG-2 TS components to layer mapping
