Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems require manual network parameter setting changes for receiving IP packets from multiple transmission apparatuses, leading to operational inefficiencies and risks of errors during transition periods, potentially disrupting video relays.
Innovation Solution
An automatic packet reception apparatus that uses a packet receiving unit, a transmission source identifier table, and buffer management to store and extract IP packets based on transmission source identifiers, allowing for seamless reception without resetting network parameters, even during changes in transmission sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual network parameter setting changes are performed for each transmission source, then reception accuracy is improved, but operation complexity and time consumption increase
Solution Approach 1:
The reception apparatus automatically identifies transmission sources using transmission source identifiers in received packets and autonomously switches reception settings without requiring manual intervention. The system serves itself by automatically detecting when to change network parameters based on packet analysis, eliminating the need for operators to manually configure settings for each transmission source.
Solution Approach 2:
The system pre-configures multiple network parameters in advance corresponding to different transmission sources. When a transmission source identifier is detected in incoming packets, the apparatus quickly switches to the pre-prepared corresponding network parameters, avoiding time-consuming manual configuration during actual reception operations.
2Productivity
If automatic packet reception is implemented without network parameter resetting, then operational efficiency is improved, but packet confusion may occur from multiple transmission sources
Solution Approach 1:
The reception apparatus segments packets from different transmission sources by identifying and separating them using unique transmission source identifiers embedded in each packet. This allows the system to maintain continuous automatic reception while reliably distinguishing and processing packets from multiple sources without confusion, even without resetting network parameters between sources.
Solution Approach 2:
The transmission source identifier acts as an intermediary element that enables the reception apparatus to differentiate between packets from different transmission sources. By using this identifier as a mediator, the system can automatically route and process packets from multiple sources through a single continuous reception process without requiring network parameter resets, thus maintaining both efficiency and reliability.
3Measurement precision
If network parameters are reset for each transmission source, then packet reception accuracy is improved, but system complexity and operation cost increase
Solution Approach 1:
The reception apparatus automatically manages network parameter selection based on transmission source identifiers in received packets, eliminating the need for complex manual intervention systems. The system self-regulates by automatically detecting transmission sources and switching to appropriate pre-configured network parameters, reducing both operational complexity and costs while maintaining reception accuracy.
Solution Approach 2:
Instead of physically resetting or reconfiguring network parameters for each transmission source, the system efficiently switches between pre-configured parameter sets based on transmission source identifiers. This approach maintains reception accuracy by using appropriate parameters for each source while avoiding the complexity of dynamic parameter generation or physical resets.

AI summary
A packet receiving unit (4) receives an IP packet having a network parameter and a transmission source identifier. A transmission source identifier table (5) records the transmission source identifier of the received IP packet. A packet storage processing unit (6) stores the received IP packet in a first buffer (7) regardless of the network parameter if the transmission source identifier of the received IP packet coincides with a transmission source identifier recorded in the transmission source identifier table. A packet extraction/transmission unit (8) extracts the IP packet stored in the first buffer (7) from the first buffer (7) and transmits the packet.
