Building Satellite Gateway Authorization List Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Providing satellite television to multiple users within a building, such as an apartment or office building, is cost-ineffective and aesthetically unpleasing when individual antennas and hardware are required, and there is a need for secure content distribution to authorized users.
Innovation Solution
A content delivery system using a gateway that generates and manages user lists with authorization information, compares requests to authorized content or channels, and encrypts content using local keys, ensuring secure and efficient distribution to multiple user devices within a building.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual antennas and hardware are provided for each unit in a building, then each user can receive satellite television independently, but the cost increases and the building aesthetics deteriorate
Solution Approach 1:
Multiple individual set-top boxes are merged into a single gateway device that serves the entire building. The gateway consolidates satellite reception, decryption, and content distribution functions, eliminating the need for separate antennas and hardware in each unit while maintaining reliable content delivery to multiple users.
Solution Approach 2:
The gateway is designed as a universal device that performs multiple functions: receiving satellite signals, decrypting content using authorization lists, managing user permissions, and distributing content to multiple user devices simultaneously. This multi-functional approach replaces multiple specialized devices with one versatile system.
2Device complexity
If a gateway is used to distribute content to multiple users, then hardware costs and building aesthetics improve, but secure content distribution to authorized users becomes more complex
Solution Approach 1:
Authorization lists are generated and configured in advance before content distribution begins. The gateway pre-loads user permissions, encryption keys, and access rights into its memory, enabling it to automatically authenticate and control content access without real-time manual intervention. This preliminary setup simplifies ongoing authorization management.
Solution Approach 2:
The gateway acts as an intermediary between the satellite content source and user devices. It manages the complex authorization logic and encryption/decryption processes internally, shielding users from the complexity of permission management while ensuring secure content distribution based on pre-configured authorization lists.
3Ease of operation
If content is distributed without authorization verification, then system operation is simpler, but content security and access control are compromised
Solution Approach 1:
The gateway performs automatic authorization verification and content protection without requiring manual intervention. It autonomously compares user device identifiers against stored authorization lists, encrypts content before distribution, and monitors access rights. This self-service approach maintains operational simplicity while ensuring robust security through automated enforcement of access controls.

AI summary
A communication system 10 includes a head end 12 that generates a device list with channel or content authorizations. The head end communicates the list to a system gateway 26. The gateway 26 receives the list. A plurality of user devices 28 is coupled to the gateway 26. A first device of the plurality of user devices generates a channel or content request at the system gateway. The gateway 26 compares the channel or content authorizations from the list to the channel request from the first user device and communicates to the first user device a channel or content corresponding to the channel request in response to comparing. Thus, authorized users are able to receive the channel or content in response to the list. The list may be generated at a subscriber information module 52 and communicated with the content or channel through a satellite 18 or through a communication network 50.
