Abstract
A caption formatting method and computing system that receives an input video stream that includes a sequence of input transport stream packets. The method locates user data in the sequence of input transport stream packets, where the user data includes input caption data compliant with an input caption data format. The method extracts EIA-608 captions and EIA-708 captions from the input caption data, and formats the EIA-608 captions as caption data compliant with SCTE-20 format. The method creates a sequence of output transport stream packets based on the sequence of input transport stream packets, where the sequence of output transport stream packets include the caption data compliant with SCTE-20 format and the input caption data. The method sends an output video stream from the computing device, where the output video stream includes the sequence of output transport stream packets.
