Livestream Summary Generation for Midstream Viewer Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing livestreaming technologies do not effectively provide summaries that reflect the current situation of a livestream to viewers who join in the middle, leading to confusion and difficulty in understanding the content and flow.
Innovation Solution
A machine learning model generates summaries of livestreams in real-time based on time-series data, including conversation topics, flow, and viewer interactions, providing viewers with a concise overview of the current livestream situation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If livestream content is transmitted in real-time without summaries, then the livestream maintains its original flow and authenticity, but new viewers joining in the middle cannot understand the content and context
Solution Approach 1:
The system performs preliminary analysis of livestream content to generate summaries that are prepared in advance or near-real-time. These summaries capture key information, topics, and context before new viewers join, allowing them to immediately understand the ongoing content without missing important context.
Solution Approach 2:
The summary generation system acts as an intermediary between the raw livestream content and new viewers. It processes the continuous video/audio stream, extracts essential information, and presents it in a condensed format that bridges the gap between ongoing content and new audience members who need context.
2Loss of information
If detailed summaries are generated continuously, then viewer understanding is improved, but system complexity and processing requirements increase
Solution Approach 1:
The system extracts only the most essential and relevant information from the continuous livestream, rather than processing and summarizing everything. It identifies key topics, significant events, and important context, separating these from less important content to create concise summaries that maintain understanding without requiring complex processing of all stream data.
Solution Approach 2:
The summary generation system dynamically adjusts parameters such as summary length, detail level, and update frequency based on the livestream content characteristics and viewer needs. This allows the system to maintain effectiveness while optimizing computational resources by varying the processing intensity according to the situation.
3Productivity
If summaries are updated frequently to reflect current situation, then viewer engagement increases, but processing time and computational resources increase
Solution Approach 1:
The system implements periodic summary updates at strategically determined intervals rather than continuous real-time generation. It balances the need for current information with processing efficiency by updating summaries at rates that maintain viewer engagement while allowing computational resources to recover between processing cycles.
Data Source
AI summary
A server includes a circuitry, wherein the circuitry is configured to: obtain, at a first point of time during progress of a livestream, first time-series data representing content of the livestream recorded as the livestream progresses; generate summary information of the livestream as of the first point of time based on the first time-series data obtained; obtain, at a second point of time during progress of the livestream later than first point of time, second time-series data representing content of the livestream recorded as the livestream progresses; and generate summary information of the livestream as of the second point of time based on the second time-series data obtained.
