Method and system for transmitting audio-associated text information in a multiplexed transmission stream
First Claim
1. A method of transmitting text information associated with individual songs transmitted via a multiple-channel audio/video transmission network, said method comprising:
- receiving text information associated with a first song;
formatting said text information into song data;
inserting said song data into a control data stream associated with an audio-only channel carrying said first song;
multiplexing said control data stream with a data stream associated with said audio-only channel and a video data stream associated with a video channel to form a multiplexed data stream;
transmitting said multiplexed data stream;
receiving said multiplexed data stream;
decoding said multiplexed data stream with a decoder to obtain text associated with said text information; and
displaying said text in association with output of the audio of said song.

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.
