Filtering done by receiver, each STB software have a filter for service type of each channel. Your receiver will not see those channels what have in SDT wrong value.
Before the ViP game, those service types was consistent and had real meaning, like HiDef chahhels - only HiDef receivers capable to process them; OpenTV - well, those who have interactive support, etc.
But the recent 'ViP only' value is something outrangeous. It's cut off legitime HD receiever from compatible type of compession programms. Pure manure.
