Live Video Call-In Server for Real-Time Audience Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current live video streaming technologies do not enable real-time call-in participation from viewers, limiting audience engagement and interaction during online broadcasts.
Innovation Solution
A method and system for call-in participation in live video streaming, where a server alerts viewers of participation options, receives audio/video specifications, establishes bi-directional communication, and mixes viewer streams with the live broadcast, allowing selected participants to interact without hearing their own audio signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If live video streaming is implemented without call-in features, then the system complexity remains low and operation is simple, but audience engagement and interaction are limited
Solution Approach 1:
The system segments the live stream into multiple independent tracks (video, audio, data) that can be selectively mixed. Viewer call-in streams are segmented and integrated into specific tracks without disrupting the main broadcast, allowing engagement features to be added modularly without increasing overall system complexity
Solution Approach 2:
An intermediary server component manages the complexity of call-in participation by handling stream mixing, audio routing, and participant coordination. This intermediary absorbs the system complexity, keeping the client-side media player operationally simple while enabling sophisticated audience engagement features
2Productivity
If viewer audio streams are mixed into the live broadcast, then real-time interaction is enabled, but viewers may hear their own audio signals causing feedback loops
Solution Approach 1:
The harmful component (viewer's own audio signal) is extracted and removed from the mixed stream before being sent back to the viewer. The audio mixing system separates the viewer's contribution from the broadcast mix, preventing feedback loops while maintaining real-time interaction capability
Solution Approach 2:
The system implements controlled feedback by monitoring viewer audio streams and dynamically adjusting the mix to prevent feedback. The audio processing system continuously analyzes signal levels and automatically suppresses feedback paths while preserving legitimate interaction, turning a potential harmful effect into a managed feature
3Adaptability or versatility
If multiple viewer streams are received and processed in real-time, then audience participation increases, but server processing load and network bandwidth requirements increase
Solution Approach 1:
The system processes only the necessary portions of viewer streams at full quality (audio for mixing, video for selection). Not all viewer streams are processed simultaneously at maximum quality - only selected participants receive full processing resources, reducing server load while maintaining meaningful audience participation
Solution Approach 2:
The system dynamically changes processing parameters based on participant count and system load. Video quality, audio sampling rates, and processing priority are adjusted in real-time to optimize server resource utilization while maintaining adequate participation capabilities, allowing the system to scale with audience size without linearly increasing processing load

AI summary
Methods and apparatus, including computer program products, for call-in participation for a live video broadcast. A method includes, in a server residing in a network of interconnected computers, alerting a media player of a call-in feature during a live streaming broadcast, receiving an indication from a viewer of the media player to participate in the live streaming broadcast, receiving audio/video device specifications from the media player, and dispatching an active participant stream to be used in conjunction with the live streaming broadcast.
