Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication and broadcasting network infrastructures require separate systems and equipment for different services, leading to high costs and increased burden on consumers, as they are not integrated, and there is a growing demand for a combined communication and broadcasting service using a single transmission line and receiver.
Innovation Solution
A combined communication and broadcasting dual switching system is configured with dual lines between an Optical Line Terminal (OLT) and broadcasting transmission means, where an optically converted broadcast signal is automatically switched to the active path of the OLT and output, using an optical detection unit, active path determination unit, optical switch unit, and combining unit to multiplex the signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate systems and equipment are used for communication and broadcasting services, then service reliability is maintained, but device complexity and cost increase
Solution Approach 1:
The patent combines communication and broadcasting services into a single integrated network infrastructure. The OLT (Optical Line Terminal) handles both Internet data signals and broadcast signals through dual line configurations, merging previously separate transmission systems into one unified platform that reduces device complexity while maintaining service reliability through redundant pathways.
Solution Approach 2:
The OLT is designed with multi-functionality to handle both communication services (Internet data) and broadcasting services simultaneously. The system uses universal optical transmission lines that can carry multiple types of signals, allowing a single device to perform multiple functions that previously required separate dedicated equipment.
2Stability of the object's composition
If separate systems are used for different services, then service stability is maintained, but cost increases
Solution Approach 1:
The patent merges communication and broadcasting services into a single network infrastructure, reducing the quantity of equipment needed. By using shared optical lines and a unified OLT system, the patent decreases the overall cost of deployment and operation while maintaining service stability through proven transmission technologies.
Solution Approach 2:
The integrated system provides universal service delivery through a single platform that handles both Internet and broadcast traffic. This multi-functionality reduces the need for multiple separate systems, thereby lowering costs while maintaining the stability required for both service types through standardized optical transmission protocols.
3Reliability
If dual lines are configured for automatic switching, then service reliability improves, but device complexity increases
Solution Approach 1:
The system performs preliminary configuration of dual optical lines and switching pathways before service deployment. The OLT is pre-configured with automatic switching capabilities that detect signal presence and activate appropriate pathways without requiring complex real-time decision-making, thereby improving reliability while keeping control mechanisms relatively simple.
Solution Approach 2:
The automatic switching system operates autonomously by detecting which optical line is actively transmitting signals and automatically routing broadcast content through the appropriate pathway. This self-service switching mechanism improves reliability by eliminating manual intervention while keeping the control logic relatively simple through automatic signal detection and pathway selection.

AI summary
Disclosed herein are a combined communication and broadcasting dual switching system and method. The system includes broadcasting transmission means, an Optical Line Terminal (OLT), an optical detection unit, an active path determination unit, an optical switch unit, and a combining unit. The broadcasting transmission means converts a Radio Frequency (RF) broadcast signal into an optical signal. The OLT includes dual lines and selectively outputs an Internet data signal. The optical detection unit detects a line from which the Internet data signal is being output. The active path determination unit determines that the line is an active path. The optical switch unit receives the optical signal from the broadcasting transmission means, and switches to the active path. The combining unit receives the optical signal output after having been switched, receives the Internet data signal from the OLT, and multiplexes the received optical signal and the received Internet data signal.
