|20150245080||SYSTEM AND METHOD TO DETECT GARBLED CLOSED CAPTIONING - A garbled closed captioning detector analyzes closed captioning data at predetermined intervals to determine whether a metric derived from the closed-captioning data exceeds a threshold. If the metric exceeds the predetermined threshold, the closed captioning data is presumed to be garbled. For example, the metric may be the percentage of words in the closed captioning data having a desired word length observed in a particular interval compared to all words in the closed captioning data observed in the interval. If the percentage of words having a desired word length exceeds a predetermined threshold, the closed captioning data is presumed to be garbled.||08-27-2015|
