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.

V-Chip is encoded in the Extended Data Services (XDS) that is part EIA-608 captions. How it is actually transported in/with the video depends the signal type and medium.

It can be decoded in software. However, I don't know of any tools that aren't part of something larger, like transcoding, that can do it.

    Looks like tools like mediaInfo can show it from a .ts file. – Tina J Jan 14 at 17:08
