IP-Based Satellite Radio Distribution for Controlled Facilities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite radio and internet broadcasting services face challenges in providing reception inside buildings with metal and concrete structures, such as jails and prisons, where signal reception is limited or blocked, and there is a need to control access to specific content for inmates and staff.
Innovation Solution
A system that extracts satellite or internet channels, converts them to IP packets, and streams them over an Ethernet network, allowing selective access through media receivers using wireless protocols, with an administrative workstation controlling user access and channel distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite radio signals are received using traditional direct reception methods, then clear sky view is required for signal reception, but reception inside buildings with metal and concrete structures is limited or impossible
Solution Approach 1:
The patent introduces an intermediary system consisting of external satellite signal receivers, IP packet converters, and internal distribution networks that mediate between satellite signals and internal receivers. This intermediary infrastructure allows signals to be received outside the facility and distributed internally through Ethernet networks and wireless access points, bypassing the blockage problem of metal and concrete structures while enabling reception in previously inaccessible locations.
2Ease of operation
If unrestricted satellite or internet services are provided to facility residents, then content access freedom is improved, but staff control over desirable and undesirable content is lost
Solution Approach 1:
The patent segments the content distribution system into controllable components where different channels can be selectively enabled or disabled. The infrastructure allows staff to configure which satellite or internet channels are made available to residents through the IP-based distribution network, providing granular control over content access while maintaining system simplicity through standardized networking protocols.
Data Source
AI summary
A system for receiving satellite radio signals and/or internet content and extracting a plurality of channels from the satellite radio signals and/or internet content is disclosed. The content of the channels is converted to IP packets and streamed across an Ethernet network. In one embodiment, each of the channels is associated with an IP address or port. Users receive the content of the channels by selecting the IP address or port associated with the desired content. An administrator may control the channels that are available to the users. In one embodiment, the users each have a subscription to access the content, and the subscription may control the channels that the user access.
