#11 Cell ID:
This is a 16-bit field which uniquely identifies a geographic cell in a DVB-T2 network. A DVB-T2 cell
coverage area may consist of one or more frequencies, depending on the number of frequencies
used per T2 system. If the provision of the CELL_ID is not used, this field shall be set to '0'.
#12 MISO:
MISO stands for Multiple Input, Single Output (meaning multiple transmitting antennas but one
receiving antenna). MISO processing consists of taking the input data cells and producing two
similar sets of data cells at the output, each of which will be directed to the two groups of
transmitters. When using the MISO feature, StreamXpress can output the TX1 first group of cells, TX2
second group of cells or can output the sum of both TX1 and TX2.
If MISO is not used select NONE.
3.5.10.2 PLP#0
DVB-T2 allows for the transmission of multi PLP (Physical Layer Pipe) but the StreamXpress is only
capable of sending PLP#0. For streaming multi PLP, the T2Xpress software from DekTec can be
used. Contact DekTec at
for more information. This section allows the setting of
the PLP#0 transmission parameters.
