Abstract

Recovering data (e.g., closed captioning data, teletext data) encoded in television signals. A line encoding the data is over-sampled. The resulting samples are examined to determine the average number of samples spanning the low and high values in a run-in period. The average numbers are used to determine the sampling clock and the samples which represent the encoded data. By using the two average numbers, any errors which may be otherwise encountered due to factors such as ghosting may be eliminated or avoided.
