Automated Splice Point Calibration in Television Playout Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for managing splice points in television programming, such as inserting black video or relying on visual inspection, are inefficient and lead to splicing errors that reduce media inventory and viewer experience, as they are prone to human error and time-consuming correction processes.
Innovation Solution
A system and method for validating and calibrating splice points in interstitial content using automated detection of metadata offsets, where SCTE-104-based digital ad-markers are inserted to align transitions between content items, allowing for real-time correction of splicing errors and maintaining the playout schedule.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual inspection or black video insertion is used to manage splice points, then splice errors can be detected, but the process is time-consuming and reduces media inventory
Solution Approach 1:
The patent replaces manual visual inspection with an automated system that uses metadata (SCTE-104 markers) to detect and validate splice points. The system automatically compares actual splice points with scheduled splice points, eliminating the need for time-consuming manual review while maintaining or improving detection accuracy.
Solution Approach 2:
The system enables self-validation of splice points by automatically inserting metadata markers and comparing them against the playout schedule. The automated detection and correction process operates without human intervention, allowing the system to self-correct splice errors in real-time.
2Productivity
If metadata insertion is used to trigger transitions, then media inventory is improved, but splicing errors may still occur due to erroneous metadata insertion
Solution Approach 1:
The system implements a feedback mechanism where inserted metadata markers are automatically detected and validated against the scheduled playout timeline. If discrepancies are found (such as early or delayed transitions), the system generates alerts and enables automatic correction by adjusting the splice points to match the scheduled timing, ensuring accuracy while maintaining media inventory utilization.
3Reliability
If manual rework is performed to compensate for detected errors, then splice accuracy is improved, but the process takes several days or weeks
Solution Approach 1:
The system performs preliminary validation of splice points by continuously monitoring metadata markers during playout. Errors are detected and corrected in real-time or near-real-time, preventing the accumulation of errors that would require extensive manual rework later. This proactive approach reduces correction time from days or weeks to minutes or hours.
4Reliability
If black video is reserved near splice points to mask errors, then splicing errors are not noticeable, but media inventory is reduced and viewer experience is devalued
Solution Approach 1:
The patent replaces the mechanical workaround of inserting black video with an intelligent automated detection and correction system. By using metadata validation and real-time monitoring, the system achieves error masking through precise splice point control rather than visual concealment, thereby preserving media inventory and maintaining viewer experience.
Data Source
AI summary
A television playout system that handles playout of a channel, receives a video feed of the channel comprising programming data and a plurality of interstitial content items, and a playout schedule of the channel. Metadata comprising a pre-roll value is inserted at a first insertion point related to a first interstitial content item of the plurality of interstitial content items, based on the playout schedule. An offset is detected in the metadata, based on the first insertion point of the metadata in the video feed, the pre-roll value, and a time-code (TC) jump associated with a second interstitial content item in the video feed. One or more control parameters associated with the insertion of the metadata are calibrated, based on the detected offset to align a splice point related to the first interstitial content item with the TC jump associated with the second interstitial content item.
