Why do captions sometimes appear garbled or have portions of words missing?
Interference in reception is usually the culprit. Captioning problems can stem from different sources, depending on the type of broadcast, such as network, syndication, or cable. The captions are delicate, and they travel from the caption company to the broadcaster through phone lines; then go through the encoding equipment; and then get bounced to the satellites, local stations, and cable companies. They finally pass through the home receiver and are displayed on your home television. There are many opportunities for them to encounter interference that affects their quality.
