Content Placeholder Marker for Time-Shifting Live TV
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems cannot insert content placeholder markers in content streams on devices without memory storage or recording capabilities, limiting users' ability to pause and record live TV without a DVR.
Innovation Solution
The method involves receiving a request for a placeholder marker during content output, recording the content if storage is available, or storing the marker for later use if not, allowing playback from the marker position without requiring a DVR's hard drive or tuner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a device without memory storage or recording capabilities is used to process content stream, then device complexity is reduced and ease of operation is improved, but the ability to pause and record live TV is lost
Solution Approach 1:
The patent introduces a content placeholder marker as an intermediary element that enables pause functionality on non-recording devices. The marker is inserted into the content stream at the pause point and stored in memory, allowing the device to resume playback from the correct position without requiring recording capabilities. This mediator bridges the gap between limited device functionality and user pause/rewind needs.
2Reliability
If memory storage is used to record content asset, then content can be paused and rewound, but device complexity and cost increase
Solution Approach 1:
The patent extracts the recording function from the primary content processing device by using a separate memory storage component. The content placeholder marker is stored in memory rather than requiring the main device to have recording capabilities. This separation allows the content processing device to remain simple while still enabling pause and rewind functionality through the extracted memory storage component.
3Ease of operation
If conventional pause request is issued, then content can be paused, but recording device must begin recording from the time of request which is impossible without memory storage
Solution Approach 1:
The patent changes the fundamental parameter of how pause is implemented - instead of requiring continuous recording from the pause point, it uses a content placeholder marker that captures the pause position and stores it in memory. This parameter change transforms the pause mechanism from a recording-dependent operation to a memory-based operation, enabling pause functionality on devices without recording capabilities while maintaining adaptability across different device types.
Data Source
AI summary
Content placeholder markers may be provided. A request to insert a placeholder marker may be received during output of a content asset to a device. If memory storage is available to record the content asset, the asset may be recorded. Otherwise, the placeholder marker may be stored and/or used to resume playback of the content asset from another source.
