I'm trying to retrieve and decode V-chip data from my TV streams (NTSC/ATSC digital streams). Apparently these data are embedded somewhere in the stream itself, but I have no clue how they are embedded inside, if they are inside visual frames, or a different hidden channel.
How are they embedded in the stream? And how can I retireve these data? Is there a software tool to get those signals? I need to do this programmatically in code.
