Fix broadcast type value handling error

Some "UI Broadcast Type" such as "Digital Satellite" (0x80) or "Digital Communications Satellite" (0x90) are not handled correctly because they become minus value after casting from byte to integer".
Add the mask to upper byte to get original definition value.
