The document discusses a proposed system to provide electronic program guides (EPGs) for analog cable TVs in India by detecting the channel logo of the currently viewed program. The system would localize and recognize the channel logo, download the corresponding EPG data from the internet, and render the EPG information blended with the TV video. A demo was presented capturing a TV screen during channel changes, showing the logo detection and EPG fetching and rendering. The solution could enrich the viewer experience for analog cable TV users and provide multiple levels of EPG data in a hierarchical manner by linking to additional online information.

Value Proposition
• Enriches the user's experience while watching the TV with analog signal.
– Useful to Analog Cable TV Viewers (majority in India)
• Multiple levels of EPG data can be made available in a Hierarchical manner
• User can click and chose level of Information wanted
• Level of details can be expanded using Internet
– like a movie EPG can have an Actor’s name and clicking on it can take the user to the
Actor’s Home Page
