Patent No. EP4351156 (titled "Generating Media Control Information In An Interactive Media Content Delivery System") was filed by Adeia Guides on Apr 11, 2007. The application was issued on Apr 2, 2025.
A system for enabling interactive media content delivery over one-way media networks, such as cable or satellite TV, by establishing a backchannel communications link between the user's equipment and the media content provider. The system includes a clearinghouse server that enables communication between the user's equipment and the provider's distribution facility, regardless of the provider's communication protocols or information formats. The user's equipment sends media control messages to the clearinghouse, which forwards them to the provider, enabling interactive control of media content delivery.
