Cable Captioning Problems

Some Comcast customers are having a problem with closed captioning. The cable provider's digital terminal adapters have a bug, causing the devices to display closed-captioning text incorrectly. Characters are repeated in two-letter segments. For example, "effective" was displayed as "efeffefectctivive e." Comcast is blaming the supplier of the terminal adapters, Thomson, for the problem. The under $50 units are designed to convert a digital program lineup into analog format. The Comcast program offering the devises is called Project Cavalry and is mainly having problems in these areas: San Francisco, Portland, Washington state, Philadelphia, and Chicago.
