Media Content Recording Start Time Adjustment via Closing Credits Detection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing media recording systems often fail to capture the entirety of a user-specified media content event due to mismatched recording start and end times, particularly when preceding events extend beyond their scheduled end times, leading to incomplete recordings.

Innovation Solution

A system that monitors the concluding portion of a preceding broadcasting media content event for its closing credits, adjusts the recording start time accordingly, and extends the recording end time if necessary to ensure the entire user-specified event is recorded, using image analysis and optical character recognition to identify closing credits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the recording start time is set according to the scheduled broadcast start time, then the recording can begin at the expected time, but the recording may capture incomplete or unwanted content from the preceding event

Engineering Contradiction:

Improverecording start time accuracyVSAvoidrecording content completeness

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The system performs preliminary analysis of the preceding event's closing credits before the scheduled recording start time. By detecting the closing credits text in advance, the system prepares to adjust the recording start time to ensure complete capture of the target event without including unwanted portions of the preceding event.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the broadcast stream for closing credits text during the period before the scheduled recording start time. Based on the feedback from detecting whether closing credits are present, the system dynamically adjusts the recording start time to achieve accurate recording boundaries.

Inventive Principle:

Principle #23Feedback

2Loss of time

If the recording end time is set according to the scheduled broadcast end time, then the recording can end at the expected time, but the concluding portion of the target event may be omitted

Engineering Contradiction:

Improverecording end time accuracyVSAvoidrecording content completeness

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The system performs preliminary monitoring during the target event to detect when closing credits appear. By identifying the closing credits in advance, the system can proactively extend the recording end time to ensure the complete capture of the target event's concluding portion.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously analyzes the broadcast stream during the recording period to detect closing credits text. Based on the feedback from detecting closing credits, the system dynamically extends the recording end time beyond the scheduled end time to capture the complete event content.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If fixed recording time boundaries are used based on EPG information, then the recording process is simple and predictable, but the recording may include unwanted content or miss important content due to timing mismatches

Engineering Contradiction:

Improverecording process simplicityVSAvoidrecording content accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system replaces the mechanical approach of using fixed time boundaries from EPG information with an intelligent content-based detection system. By substituting automated text recognition and pattern matching for simple time-based scheduling, the system achieves both operational simplicity and high recording accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system introduces closing credits text detection as an intermediary mechanism between the EPG scheduling information and the actual recording process. This intermediary layer analyzes the broadcast content to determine precise recording boundaries, bridging the gap between scheduled times and actual event boundaries.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Systems and methods are operable to record a user-specified media content event at a media device. An exemplary embodiment grabs a series of subsequently received image frames from a preceding broadcasting media content event after a monitored real time reaches a closing credits monitor time, wherein the closing credits monitor time is a recording start time less a predefined duration. The embodiment then analyzes each of the image frames to identify an occurrence of text presented in the analyzed image frame, determines that the identified text corresponds to closing credits of the preceding broadcasting media content event if the at least one attribute of the identified text matches a corresponding predefined closing credits attribute, and initiates a start of the recording of the user-specified media content event in response to determining that the identified text corresponds to the closing credits of the preceding broadcasting media content event.
