Time Delayed Playback Feed Integrity via Chunked Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Time delayed playback systems face issues with feed integrity due to discrepancies in recording and device failures, leading to incomplete or missing content in playback feeds, particularly across different time zones, which affects revenue and viewer experience.
Innovation Solution
The system employs a TDP device and a secondary TDP device to record and store content in chunks, with a playlist source device that automatically identifies and corrects errors by inserting missing commercials or content, and a secondary device providing backup to ensure continuous playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a TDP system records and stores feed for subsequent playback in different time zones, then the system enables time delayed playback across time zones, but the integrity of the recorded feed may be compromised due to recording discrepancies or device failures
Solution Approach 1:
The system performs preliminary actions by recording the feed in multiple separate chunks before playback occurs. This segmentation allows the system to prepare redundant copies in advance, so that if one chunk is corrupted or missing, other chunks remain intact and can be used to reconstruct the complete feed, thus maintaining feed integrity while enabling time delayed playback
Solution Approach 2:
The feed is divided into multiple separate chunks or segments for recording and storage. This segmentation isolates potential errors to specific chunks rather than affecting the entire feed, allowing the system to identify and correct errors in individual chunks while maintaining overall feed integrity across different time zones
2Device complexity
If the TDP system uses a single recording device to store feed chunks, then the system simplifies the device configuration, but the system becomes vulnerable to device failures that cause missing or incomplete feed data
Solution Approach 1:
The system combines multiple recording devices to work together in recording and storing feed chunks. This redundancy ensures that if one device fails, other devices have recorded copies of the feed chunks that can be used to complete the playback feed, thereby maintaining feed completeness while distributing the recording load across multiple devices
3Quantity of substance
If the TDP system records complete feed content including commercials, then the system ensures complete content for playback, but errors such as commercials failing to play out correctly can propagate to the playback feed
Solution Approach 1:
The system implements feedback mechanisms that monitor the recorded feed chunks for errors such as commercials failing to play out correctly. When errors are detected in the recorded content, the system can identify and correct these errors before playback, ensuring that the playback feed contains accurate content while maintaining completeness of all feed elements including commercials

AI summary
A system and method that time delays a playback from a first feed at a first time to a second feed at a second time. The method includes recording the first feed that is received at the first time to be used at least partially as a playback of the second feed at the second time. The second time has a predetermined delay relative to the first time. The method includes determining whether the first feed has a discrepancy in the actual playback from a desired playback. The discrepancy is at a known time and lasting a known time amount. The method includes transmitting the playback to the second feed after the predetermined delay. A fix is aired instead of the playback for the known time amount corresponding to the discrepancy.
