Mediation Module for Caller ID Delivery to IPTV Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional television distribution systems, such as terrestrial, satellite, and cable TV, do not support real-time packet switching, making it difficult to deliver caller ID information to IPTV devices without complex wiring and potential security risks, whereas IP-based systems lack efficient methods for network-based caller ID notification.
Innovation Solution
A network-based system that integrates caller ID information from telephony networks into IPTV networks using a Mediation Module with a Mediation Database, Mediation Message Server, and Web Portal, facilitating the conversion and delivery of caller ID notifications to IPTV set-top boxes via SIP and HTTP/XML protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If analog signal based caller ID devices are attached to phone jacks using RJ-11 cables to enable caller ID notification to television display, then caller ID notification is achieved, but installation becomes technically difficult and operationally undesirable
Solution Approach 1:
The patent introduces a cable set-top box as an intermediary device that receives caller ID information from the cable system and displays it on the television screen. This mediator eliminates the need for direct RJ-11 cable connections between phone jacks and television equipment, simplifying installation while maintaining reliable caller ID notification functionality.
2Device complexity
If traditional television distribution technologies are used, then system simplicity is maintained, but real-time packet switching and caller ID delivery to IPTV devices cannot be achieved
Solution Approach 1:
The cable set-top box is designed with multi-functionality, serving both traditional television distribution and IPTV services with packet switching capabilities. This universal device handles both analog/cable signals and digital IP packets, enabling caller ID delivery to IPTV devices without requiring separate dedicated infrastructure.
3Adaptability or versatility
If network-based caller ID delivery to IPTV devices is implemented, then caller ID information can be delivered to modern displays, but security risks and integration complexity increase
Solution Approach 1:
The set-top box acts as a secure intermediary that receives caller ID information through established cable system protocols and displays it on the television screen. This approach avoids direct integration with potentially vulnerable IPTV networking components, reducing security risks while maintaining the ability to deliver caller ID information to modern displays.

AI summary
Network-based methods and systems transfer caller ID information from a telephony network to an IPTV network. Embodiments integrate service provisioning, subscriber account and policy information between telephony services and IP-based television services. Voice call signaling may be intercepted to retrieve caller ID, caller name information, and other call management information, at the call server in the network to deliver an appropriate notification message to the IP-based TV network at its notification server, which in turn sends a message notification to the called party's TV screen. Call log information may also be retrieved and displayed. SIP call forking and IP multimedia subsystem approaches are described.
