AV Server System IP Port Expansion and Frame Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AV server systems face challenges in easily increasing the number of IO ports and storage capacity while maintaining efficient data processing and synchronization across multiple servers.
Innovation Solution
The AV server system employs IP input-output ports for inter-server connections, a client controller for managing AV servers, and a frame synchronization unit for synchronizing frames across multiple AV servers, allowing for flexible configuration and increased storage capacity through compression and decoding processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of IO ports is increased by separating AV storage unit from input-output devices, then the number of IO ports is increased, but the device complexity increases
Solution Approach 1:
The system is divided into multiple independent AV servers, each with its own storage unit and input-output devices. This segmentation allows the number of IO ports to be increased by adding more server units rather than complicating a single server's internal structure, thereby resolving the contradiction between increasing IO port quantity and maintaining device simplicity.
2Quantity of substance
If multiple AV servers are connected via network, then the storage amount is increased, but the frame synchronization between servers becomes more difficult
Solution Approach 1:
The system implements a frame synchronization mechanism where each AV server monitors and adjusts its frame output timing based on feedback from the networked environment. This feedback-based synchronization ensures that even as storage capacity scales by adding more servers, the frame synchronization precision is maintained through continuous adjustment and coordination.

AI summary
To increase the number of IO ports and to increase the storage amount easily. An AV server system includes: a plurality of AV servers including internet protocol (IP) input-output ports for connecting to other AV servers, the IP input-output ports being independent from input-output ports to an outside of the system; a client controller configured to control the plurality of AV servers; a manager storing information relevant to AV clip data recorded in the plurality of AV servers and AV clip data input into the plurality of AV servers; and a frame synchronization unit configured to perform frame synchronization between the plurality of AV servers.
