4) Enable ASI INTERFACE
It enables or disables the ASI interface. Refer to that section.
5) TS Layers
It indicates layers used by the demodulator to generate the TS. The default value is
"A + B + C", so the TS will be built with data from these three layers. If Partial
Reception is available, you should choose "A" if you want just a TS with partial
reception information. Keep in mind that the layers assigned to the TS will affect the
MPEG-2 / H.264 Decoder so the list of services can change depending on the
selected layers.
6) Layer
Information about encoding parameters for each layer during the hierarchy
transmission. The layer can be selected (A, B or C) depending on what is the layer
active at the channel.
This configuration menu shows, besides the user definable ISDB-T/T
parameters, the value of the rest of signal parameters detected automatically:
Bandwidth:
Code Rate:
Modulations:
High layer:
Partial reception:

It shows the channel bandwidth.
Also known as Viterbi ratio, defines the ratio between the data
bits number and the total number of bits transmitted (the
difference corresponds to the number of control bits for the error
detection and recovery).
Carriers modulation. It also defines the system noise immunity.
(QPSK, 16-QAM and 64-QAM).
It shows information about the high priority layer.
It shows If it is or not possible the partial reception.
