Abstract
Disclosed is a system and method of combining traditional programming caption data with advertising caption data in a single closed caption data stream. Advertising caption data is received from a data warehouse. When such advertising caption data is encoded into the closed caption data stream, it must temporally displace the traditional programming caption data that would otherwise be displayed. Thus, such programming caption data is buffered during display of the advertising caption data, and then is played out in an intelligent yet accelerated manner to maintain readability and recover the time lost during the sponsorship event.
