PVR Overtime Recording via Metadata Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital video broadcasting (DVB) systems do not effectively handle the scenario where a recorded video program extends into overtime, as they lack the capability to automatically continue recording beyond the initially set duration, especially for events like sports games that go into extra time.
Innovation Solution
A method and system for a personal video recorder (PVR) to continue recording a multimedia content item beyond the initially set time by utilizing metadata, such as DVB Service Information (SI) and proprietary service information schemes, which include parameters for determining additional recording time based on user input, broadcaster settings, or genre-specific defaults.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the PVR records video content for a fixed duration based on metadata, then the recording process is simple and reliable, but the recording may end prematurely when the actual content duration extends beyond the metadata duration (overtime)
Solution Approach 1:
The system continuously monitors the actual running time of the recorded content against the metadata duration. When the actual content duration exceeds the metadata duration (indicating overtime), the system receives feedback about this discrepancy and automatically extends the recording duration accordingly, ensuring complete capture of the content without requiring user intervention or complex manual control
Solution Approach 2:
The system pre-configures the recording duration based on metadata information before recording begins. However, when overtime is detected during playback, the system proactively extends the recording without waiting for user input or complex decision-making, by automatically adjusting the recording stop time based on the detected overtime condition
2Extent of automation
If the PVR automatically extends recording time based on detected overtime, then recording completeness is improved, but the system complexity and processing requirements increase
Solution Approach 1:
The system performs self-monitoring of the recorded content duration and automatically adjusts its own recording parameters without external intervention. The PVR compares the actual content duration with the metadata duration, detects overtime conditions, and autonomously extends the recording accordingly, eliminating the need for complex user interfaces or manual control mechanisms
Solution Approach 2:
The system dynamically changes the recording duration parameter based on the detected overtime condition. When overtime is detected, the system modifies the recording stop time parameter to extend beyond the original metadata duration, allowing automatic adaptation to varying content lengths while maintaining simple system architecture through parameter-based control

AI summary
A method and system for adding overtime to a video recording are described. The method and system include providing a personal video recorder (PVR) operative to record a video stream, providing a multimedia content item on the video stream, providing metadata accessible to the PVR, the metadata being associated with the multimedia content item and including at least a first metadata item and a second metadata item, recording the multimedia content item at the PVR for a first amount of time, the first amount of time being indicated by the first metadata item, continuing to record the multimedia content item after the end of the first amount of time, for a second amount of time based, at least in part, on at least one parameter in the second metadata item.
