Live Media Stream Missed Content Stitching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users miss portions of live-streamed media content due to connectivity issues, such as intermittent connections and low bandwidth, and are often unable to seamlessly rejoin the stream upon restoration, missing critical moments like key events in sports or news.
Innovation Solution
A system that logs timestamps of connectivity failures and restorations, retrieves and stitches together missed portions of media content streams, allowing users to view missed content either during or after the live stream, using user devices and servers to store and manage recorded content for playback, with optional additional content for context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users continue watching live stream from the point where connection is restored, then bandwidth and connectivity requirements are reduced, but users miss critical portions of the content
Solution Approach 1:
The system pre-records the live media content stream during the failure period before the user requests playback. Timestamps are logged in advance during connectivity failures, and the corresponding recorded portions are prepared and stored beforehand, so when the user requests missed content, it is immediately available for playback without retrieval delay.
2Reliability
If the system retrieves and stores recorded portions for all connectivity failures, then content coverage completeness is improved, but device and server storage requirements increase
Solution Approach 1:
The system applies different storage strategies based on the duration of the connectivity failure. For failures exceeding a first threshold period, the entire recorded portion is stored. For failures between a second and first threshold period, only a highlight portion is stored. For failures below the second threshold period, no storage occurs. This localized quality approach optimizes storage usage based on the specific needs of each failure event.
Solution Approach 2:
The system extracts and stores only the highlight portion of the recorded content for failures of moderate duration (between second and first threshold periods). Instead of storing the entire recorded portion, the system identifies and extracts only the critical or highlight segments that are most likely to be of interest to the user, thereby reducing storage requirements while maintaining content coverage completeness.
3Reliability
If the system provides all missed content to users, then content coverage completeness is improved, but data transmission and processing requirements increase
Solution Approach 1:
The system extracts and transmits only the highlight portion of the missed content for failures of moderate duration. Instead of transmitting the entire recorded portion, the system identifies and extracts only the critical or highlight segments, reducing data transmission requirements and processing load while still providing users with the most valuable content from the missed period.

AI summary
Systems and methods are described for viewing missed media content. A media content stream is received at a user device. A first timestamp is logged, in response to determining a first failure in the receiving of the content stream, indicating when the first failure in the receiving of the content stream to the user device occurred. A second timestamp is logged, in response to determining a first restoration of the receiving of the content stream, indicating when the first restoration in the receiving of the content stream to the user device occurred. A first recorded portion of the media content stream is retrieved. The first recorded portion has a start point corresponding to the first timestamp and an end point corresponding to the second timestamp.
