Process for associating and delivering data with visual media
First Claim
1. A process for associating and delivering data with a video signal, comprising the steps of:
- encoding a video source signal by inserting data in unused video bandwidth of the video source signal between the safe viewable area and the blanking portion;
transmitting the encoded video source signal;
decoding the encoded video source signal; and
visually displaying the data or audibly delivering the data to an end user.

Abstract
A process for associating and delivering data with a video signal includes digitizing an analog data signal. The digitized data is then compressed and transcoded into a format compatible with a video source signal. The data is then inserted into unused video lines of the video source signal outside the vertical and horizontal blanking internet. The encoded video source signal is transmitted to a decoder where the inserted data is separated from the video source signal. The inserted data is then converted to its original form, and either visually displayed or audibly delivered to an end user. The invention can be used to associate and deliver audio narrative description with a video signal for the benefit of the visually impaired.
