Buddy List Presence Sensing for IPTV and VoIP Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buddy list applications fail to leverage emerging entertainment and business technologies, such as IPTV, by not effectively sensing and reporting various types of user presence, limiting user interaction and collaboration across different services.
Innovation Solution
A method and system for sensing and reporting various types of user presence using buddy lists, which involves transmitting status information between client devices and a server, allowing users to initiate actions based on presence indicators like IPTV viewing, VoIP calls, or shared content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional buddy list applications are used, then basic instant messaging functionality is provided, but user interaction across emerging entertainment services like IPTV is limited
Solution Approach 1:
The buddy list application is enhanced to serve multiple functions beyond basic instant messaging. It now integrates presence sensing for various services (IPTV, VoIP, digital music players), enabling users to interact across different entertainment services through a unified interface. The system can detect and report presence status for multiple service types simultaneously, making the application versatile while maintaining a consistent user experience.
Solution Approach 2:
A presence server acts as an intermediary between client devices and the buddy list application. This server collects presence information from various services (IPTV, VoIP, etc.), processes it, and distributes it to appropriate clients. This intermediary layer simplifies the complexity by centralizing the sensing and routing logic, allowing individual services to remain independent while enabling integrated interaction.
2Ease of operation
If presence sensing for multiple services is implemented, then user interaction and collaboration are enhanced, but the difficulty of detecting and measuring presence increases
Solution Approach 1:
The presence server serves as a mediator that handles the complexity of detecting and measuring presence across different services. Each service (IPTV, VoIP, digital music player) reports its status to the server, which then formats and distributes this information to buddy list clients. This abstraction layer hides the detection complexity from end users, making interaction simple while managing measurement difficulties centrally.
Solution Approach 2:
The system implements feedback mechanisms where presence information is continuously monitored and reported. When a user's presence status changes (e.g., starting an IPTV session or VoIP call), the system detects this change, updates the buddy list status, and notifies relevant users. This continuous feedback loop simplifies interaction by automatically keeping users informed without requiring manual status reporting.
3Measurement precision
If status information is transmitted between client devices and server, then real-time presence information is available, but information transmission requirements increase
Solution Approach 1:
The system extracts only the essential presence information needed for buddy list functionality and transmits just this minimal data between clients and the server. Rather than transmitting complete service states or redundant information, the system extracts key presence indicators (online/offline status, service type) and sends only these critical details. This extraction approach maintains measurement precision for presence detection while minimizing information transmission overhead.
Data Source
AI summary
A method and system for sensing and reporting various types of user presence using "buddy list" applications. A buddy list client senses various types of user presence of a user and sends status information corresponding to the sensed user presence to a server. The buddy list client also receives status information from the server corresponding to various types of user presence information of buddies, and displays a buddy list indicating the various types of user presence information of the buddies. This can be implemented on an IPTV client in order to sense and display presence information relating to a user watching television.
