FRAGMENT BOUNDARY INDEPENDENT CLOSED CAPTIONING

摘要

A media stream is received and delineated into groups of pictures (GOPs). The GOPs are encoded and fragmented while a closed captioning monitoring system tracks fragment boundaries and adjusts closed captioning information including multi-language data and text tracks for correct presentation even in the presence of fragment boundary crossings. Encoded fragments with timing accurate closed captioning can be maintained as fragments on shared storage, even when randomly accessed.
