ABSTRACT:
A method and system for transmitting audio-associated text information in a multiple-channel transmission stream is disclosed herein. The method includes the steps of receiving text information associated with a song, formatting the information into song data, inserting the song data into a control data stream associated with an audio channel carrying a particular song, multiplexing the control data stream with a data stream associated with the song, transmitting the multiplexed data stream, receiving the control data stream, decoding the control data stream to obtain text associated with the song, and displaying the text. The method utilizes an existing control stream in the multiplexed transmission stream to forward text to a receiver. The receiver therefore requires no additional hardware to display the text on a connected video screen.
