Abstract:
A method for embedding, multiplexing and broadcasting of multiple audio metadata in an analog video stream and thereby generating output analog video containing multiple separable audio-video tuples of optimum quality. Further, a user study is performed on a sample tutorial video for various frame rates and resolution to calculate the mean opinion score for deriving the degree of multiplexing that may be provided without deteriorating the quality of video.
