Extension Bundle Generation for Video Recording Boundary Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video delivery services face challenges in accurately recording live programs due to incorrect metadata, which can result in missing content, especially when handling hand-offs between programs, and existing systems struggle to generate bundles that match user-requested recording times with extensions.
Innovation Solution
The implementation of extension bundles that dynamically or pre-calculate additional time segments before and after live programs, ensuring users can record programs with requested extensions while maintaining compliance with regulations by creating a single video that includes content from multiple programs, thus allowing seamless playback with or without extensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hard cut-off times are used for program recording, then recording boundaries are clearly defined, but hand-off segments between programs are missed
Solution Approach 1:
The system pre-calculates extension bundles that include hand-off segments before program transitions occur. By preparing extended time segments in advance that overlap with potential hand-off periods, the system ensures that when a program ends, the recording already includes the necessary hand-off content from the next program, eliminating the need for post-processing adjustments.
2Extent of automation
If metadata is used to determine program timing, then automated recording is enabled, but incorrect metadata causes wrong recording times
Solution Approach 1:
The system implements a feedback mechanism where actual program timing data is compared against metadata predictions. When discrepancies are detected (such as hand-off segments or unexpected program extensions), the system uses this feedback to adjust future recording boundaries and generate corrected extension bundles, progressively improving timing accuracy while maintaining automated operation.
3Adaptability or versatility
If extension bundles are generated dynamically, then user-specific extensions are achieved, but processing time increases
Solution Approach 1:
The system pre-calculates and stores extension bundles for various time extensions (e.g., 5 minutes, 10 minutes, 15 minutes) before users make recording requests. When a user requests a program recording with an extension, the system retrieves the pre-prepared bundle matching the user's preference rather than generating it in real-time, significantly reducing processing time while maintaining the ability to provide personalized extensions.

AI summary
In one embodiment, a method receives a request from a user for one or more extensions to a first program. The first program is associated with a first bundle that indicates the first program starts at a first time and ends at a second time. A second program that starts before the first time or starts after the second time is selected. The second program is associated with a second bundle that indicates the second program ends at the first time or starts at the second time. The method generates an extension bundle that includes information for the one or more extensions and uses the extension bundle to record an extended program for the user that includes the first program and at least a portion of the one or more extensions from the second program.
