Distributed Media File Transmission via Central Metadata Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for distributing media files, such as digital cinema packages, face challenges with high data sizes, long transfer times, and high costs due to the need for powerful server locations and unreliable systems, especially when multiple cinema locations are involved.
Innovation Solution
A method that utilizes a central control instance to manage metadata for media files, allowing receiving devices to initiate and coordinate the transmission of media files from central server devices or other receiving devices, with status updates, and employing redundancy to ensure system reliability and reduce costs by distributing data packets independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If media files are transmitted from a central server to multiple receiving devices via digital network, then distribution speed and accessibility are improved, but network bandwidth requirements and transmission costs increase
Solution Approach 1:
The patent segments the media distribution system into multiple transmitting devices that can independently transmit different data packets of the same media file to receiving devices. This segmentation allows parallel transmission across multiple network paths, improving distribution speed while distributing bandwidth requirements across multiple devices rather than concentrating them on a single central server.
Solution Approach 2:
The patent combines multiple transmitting devices into a coordinated distribution network where each device contributes to the overall transmission effort. By merging the capabilities of multiple devices, the system achieves higher aggregate transmission capacity and better utilizes available network bandwidth compared to a single central server approach.
2Power
If powerful central server locations are used to provide large transmission capacities, then media file transmission capability is improved, but system costs increase
Solution Approach 1:
The patent implements a self-service distribution model where receiving devices automatically download metadata, initiate transmissions, and manage their own media file acquisitions without requiring centralized control. Transmitting devices also independently manage their own data packets. This eliminates the need for expensive, highly powerful central servers and reduces operational costs while maintaining transmission capacity.
Solution Approach 2:
The patent creates multiple copies of media file data packets across different transmitting devices. Instead of relying on a single central server to provide all transmission capacity, the system distributes data packets to multiple devices, allowing any receiving device to obtain files from multiple sources. This copying approach reduces the transmission burden on any single device and lowers overall system costs.
3Device complexity
If a single central server location is used for media file distribution, then system simplicity is improved, but system reliability deteriorates
Solution Approach 1:
The patent segments the distribution system into multiple independent transmitting devices, each capable of providing data packets. This segmentation eliminates the single point of failure inherent in centralized systems. If one transmitting device fails, other devices continue to operate and can still fulfill distribution requests, thereby improving system reliability while maintaining manageable complexity through standardized device interfaces.
Solution Approach 2:
The patent changes the system architecture parameter from centralized to distributed. Instead of one central server, multiple transmitting devices operate in parallel with comparable capabilities. This parameter change transforms the system from vulnerable to single-point failures into a resilient network where failure of individual components does not compromise overall system availability.
4Reliability
If multiple server locations are created to provide redundancy, then system reliability is improved, but system costs multiply
Solution Approach 1:
The patent enables receiving devices to autonomously manage their own media file acquisitions by downloading metadata, selecting transmitting devices, and initiating transmissions without centralized coordination. This self-service capability allows the system to achieve redundancy through multiple transmitting devices without requiring proportional increases in centralized control infrastructure, thereby reducing the cost multiplier effect of creating redundant server locations.
