The App allows the final viewer, the installer and/or the seller to activate an official SAT HD Regional set top box, after the correct installation in the TV and the satellite dish. The user must fill the CAID field (set top box number), SCUA/SCID field (smartcard number) and indicate which city and State the set top box is installed. After a few minutes, the right feed (Regional or National) will be available to the final viewer.
