Abstract

Text is interleaved and transported along with media data over the same real-time Internet Protocol (IP) media transport session. A network processing device identifies text characters corresponding with text signaling. The identified text characters are formatted into text packets and sent over the same real-time IP media transport session used for real-time media transport. The media transport session can identify the sequence that the text characters are transmitted and can specify a maximum character transfer rate.
