Master-Slave Audio Video Network Reduces Installation Cost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio/video network systems for distributing satellite broadcast services are expensive to install and maintain, as each television requires a separate receiver with its own hardware and software, leading to increased costs for installation and ongoing service updates.
Innovation Solution
An audio/video network system with a master receiver that distributes satellite broadcast services to multiple televisions using a single antenna unit, where the master receiver processes signals and shares resources with slave clients via existing home wiring or wireless networking, eliminating the need for direct coaxial connections to each television.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each television has its own receiver directly connected to the satellite antenna, then service quality and reliability are maintained, but installation cost and device complexity increase significantly
Solution Approach 1:
The system divides the receiver functionality into two segments: a master receiver that handles signal reception and processing from the satellite antenna, and slave clients that distribute the processed signals to multiple televisions. This segmentation allows one receiver to serve multiple locations while maintaining service quality.
Solution Approach 2:
The master receiver acts as an intermediary between the satellite antenna and multiple slave clients. It receives and processes the satellite signal, then distributes it to multiple televisions through the network, eliminating the need for direct connections from each television to the antenna.
2Adaptability or versatility
If each television has its own receiver with complete hardware and software, then service functionality is complete, but installation and maintenance costs increase
Solution Approach 1:
The master receiver is designed as a universal device that performs all necessary receiver functions (signal reception, processing, decryption) and serves multiple slave clients simultaneously. This multi-functionality eliminates the need for each television to have its own complete receiver, reducing installation costs while maintaining full service functionality.
Solution Approach 2:
The system merges the functionality of multiple receivers into a single master receiver that serves all televisions in the network. By combining these functions centrally, the system reduces hardware requirements, installation complexity, and maintenance costs while preserving complete service functionality at each location.
3Reliability
If multiple coaxial cables are run from the satellite antenna to multiple locations, then direct signal reception is achieved, but installation aesthetics and cost deteriorate
Solution Approach 1:
The master receiver serves as an intermediary that consolidates the connection to the satellite antenna into a single location. Multiple televisions receive signals through the network infrastructure rather than direct coaxial cable connections, reducing visible cabling and improving installation aesthetics while maintaining signal reception quality.

AI summary
An audio/video network system for distributing satellite broadcast services includes an antenna unit for receiving audio/video broadcast services. The antenna unit is in communication with a master receiver, which receives the audio/video broadcast services and displays them on a first television associated with the master receiver. The master receiver is in communication with a plurality of slave clients, which receive audio/video broadcast services from the master receiver and display them on a respective television associated with each of the slave clients.
