Media Playback System Format Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for accessing and pausing media items across different devices and formats are not seamless, as they often require manual synchronization and format compatibility issues, limiting the ability to resume playback on various devices without losing the viewing position.
Innovation Solution
A system that uses a database to store media items in multiple formats and records the user's resume point, allowing seamless playback across devices by determining the necessary format for each device and resuming from the saved stop time, regardless of the device or format used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If media items are stored in multiple formats to support different devices, then device compatibility is improved, but storage space consumption increases
Solution Approach 1:
The media item is segmented into multiple format versions (e.g., first format, second format) stored separately in the database. Each format is optimized for specific device types, allowing the system to serve different devices with appropriate formats without requiring all formats to be loaded into memory simultaneously, thus managing storage efficiently while maintaining compatibility
Solution Approach 2:
The database is designed to universally store media items in multiple formats, making it capable of serving any device type. This multi-functional storage approach allows a single database system to handle diverse device requirements (mobile phones, tablets, computers, televisions) without needing separate storage systems for each device type
2Ease of operation
If the system automatically determines and converts media formats for different devices, then ease of operation is improved, but processing complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting the device type and selecting the appropriate media format without requiring user intervention. The processing unit autonomously determines which format (first or second format) is suitable for the connected device and retrieves or converts the appropriate format, enabling seamless operation while managing processing complexity through automated decision-making algorithms
3Duration of action of stationary object
If pause and resume functionality is maintained across different device formats, then viewing continuity is improved, but data management complexity increases
Solution Approach 1:
The system implements feedback mechanisms by continuously tracking and storing pause/resume points in the database regardless of which format or device is being used. When a user pauses playback on any device, the system records this state and uses it to restore playback continuity when the user switches devices or formats, ensuring viewing continuity while managing the complexity through centralized state tracking
Data Source
AI summary
Embodiments of the invention provide a process for a user viewing a media item. The process comprises the user viewing the media item on a first device in a first format, and the user pausing the media item at a stop time. The stop time is saved in the first format and a second format. The process further comprises the user choosing to view the media item on a second device requiring the second format. The media item is resumed in the second format from the saved stop time.
