Abstract
Methods of preserving captioning information in an input video stream through transcoding of the input video stream include extracting caption data from the input video stream, translating the caption data into at least one output caption format, packaging the translated caption data into data packets for insertion into a video stream, synchronizing the packaged caption data with a transcoded version of the input video stream, receiving a preliminary output video stream that is a transcoded version of the input video stream, and combining the packaged caption data with the preliminary output video stream to form an output video stream. Related systems and computer program products are also disclosed.
