Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media content sharing technologies in home networks require high processing capabilities and storage, leading to increased device costs due to the need for multiple bit rate backups, which is inefficient and costly.
Innovation Solution
A control device that distributes media content by selecting and assigning tasks to multiple media distribution devices within a home network, allowing them to jointly process media content in an adaptive stream format suitable for media play devices, thereby improving processing efficiency and device utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple bit rate backups are generated for media content using DASH technology, then media playback quality is improved, but device processing capability requirements and storage space increase
Solution Approach 1:
The patent segments the media processing task by dividing media content into multiple segments and distributing them to different devices in the home network for parallel processing. Each device processes specific segments independently, reducing the processing burden on any single device while maintaining the ability to generate multiple bit rate backups for quality playback.
Solution Approach 2:
The patent enables multiple devices in the home network to serve as media distribution devices with DASH processing capabilities. Instead of requiring one high-capability device, multiple devices with varying capabilities can collectively perform the media processing function, reducing individual device complexity requirements.
2Manufacturing precision
If multiple bit rate backups are generated for media content, then media playback quality is improved, but storage space requirements increase
Solution Approach 1:
The patent divides media content into multiple segments and distributes storage across different devices. Each device stores only the segments assigned to it, reducing the storage burden on any single device while collectively maintaining all necessary bit rate backups for quality playback.
Solution Approach 2:
The patent combines the storage resources of multiple devices in the home network to collectively store the multiple bit rate backups. The total storage capacity of the network is utilized rather than requiring one device to have all storage space, reducing individual device storage requirements.
3Device complexity
If a single device processes all media content, then processing control is simplified, but processing efficiency decreases
Solution Approach 1:
The patent segments the media content into multiple parts and assigns different segments to different devices for parallel processing. This segmentation enables simultaneous processing of multiple segments across the network, significantly improving overall processing efficiency while the control device maintains centralized coordination.
Solution Approach 2:
The control device acts as an intermediary that coordinates the distributed processing tasks. It assigns segments to devices, monitors processing status, and manages the overall workflow, maintaining processing control simplicity while enabling efficient parallel execution across multiple devices.
4Manufacturing precision
If device processing capability is increased to handle media content locally, then playback quality is improved, but device cost increases
Solution Approach 1:
The patent enables multiple devices with varying capabilities to participate in media processing. Devices with lower processing power can still contribute by handling specific segments or lower bit rate conversions, reducing the need for every device to have high processing capability while maintaining overall playback quality.
Solution Approach 2:
Instead of requiring each device to have full DASH processing capability, the patent allows devices to perform simplified processing or act as storage nodes for processed segments. The control device or capable devices generate the processed segments that are then distributed to playback devices, reducing individual device cost while maintaining quality.
