[V4L] Strange data encoded in the signal from a PBS affiliate

[Eric Jorgensen]

        I was flipping through channels just now and saw something I
didn't recognize on one of the local PBS affiliates. They were airing
Arthur, a popular children's animated series, and there was a vertical bar
along the top 80% of the left hand side of the screen, in the area of the
video that would probably not be visible on an overscaning tv, but which
tends to be visible on tv cards. 

        The data seemed to update a couple times a second, but didn't seem
to be entirely regular. Visually, it resembles a barcode. 

        So, I snapped a picture. Anybody know what this is?
