Set-Top Box Media Access Control via Intermediary CMS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for providing media content lack effective mechanisms to manage and enforce access restrictions, such as time-limited viewing or limited access to media content, which are essential for content sharing and billing processes across set-top box devices.
Innovation Solution
A system comprising a set-top box device with a processor, memory, and network interface that receives media content and access rules from separate sources, applies these rules to limit access, and integrates with a content management system to enforce restrictions, allowing for sharing and billing functionalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If media content is shared across multiple set-top box devices, then user accessibility and convenience are improved, but control over access restrictions and billing accuracy deteriorate
Solution Approach 1:
A content management system acts as an intermediary between the media content source and multiple set-top box devices. The CMS receives requests from user devices, determines appropriate access rules based on user profiles and content rights, and enforces these rules by providing restricted content to authorized set-top boxes. This intermediary structure enables multi-device accessibility while maintaining centralized control over access restrictions and billing.
2Reliability
If access restrictions are enforced at the destination set-top box device, then billing accuracy and content protection are improved, but system complexity increases
Solution Approach 1:
The access rule enforcement functionality is extracted from individual set-top box devices and centralized in the content management system. The CMS contains the logic for determining access rules, evaluating user entitlements, and controlling content distribution. Set-top box devices are simplified to merely receiving and displaying content according to rules enforced by the CMS, reducing device complexity while maintaining billing accuracy.
3Ease of operation
If users can view restricted portions of media content initially, then user experience and engagement are improved, but content security and full access control deteriorate
Solution Approach 1:
The system implements partial access by allowing users to view restricted portions of media content (such as trailers, previews, or limited segments) before requiring full authorization. The content management system enforces rules that permit viewing of specific portions without complete decryption keys, then requires proper authentication for full content access. This approach enhances user experience through previews while maintaining security through controlled access tiers.
Data Source
AI summary
A method includes receiving, from a set-top box device, data that indicates selected media content from a list of available media content. The method includes locating one or more content sources for the selected media content. The method includes selecting a particular content source from the one or more content sources. The method includes locating an access rules source for the selected media content. The method includes instructing the particular content source to send the selected media content to the set-top box device. The method also includes instructing the access rules source to send an access rule associated with the selected media content to the set-top box device.
