* ISDB can use different modulation types for each group of carriers.

* In order to be consistent with other delivery systems, the first

* dtv_status:scale should use the value FE_SCALE_NOT_AVAILABLE when
* the value for the entire group of carriers or from one specific layer
* is not provided by the hardware.
* st.len should be filled with the latest filled status + 1.
*
