Content Access Restriction Application for Multimedia Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia distribution networks lack precise control over access to content, particularly for children, as existing channel blocking and ratings-based methods are inflexible and imprecise.
Innovation Solution
A method and application that allow subscribers, such as parents, to define and enforce access restrictions for controlled class members, like children, through a content access restriction application, enabling preferences for TV channels, interactive games, elapsed viewing time, and monetary charges, using an authentication sequence to differentiate between subscriber and controlled class members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If channel blocking and ratings-based blocking are used, then access control is implemented, but the control is inflexible and imprecise
Solution Approach 1:
The patent segments access control into multiple independent restriction types (channel blocking, rating-based blocking, time-based restrictions, monetary charge restrictions) that can be individually configured and combined. This allows precise control over different aspects of content access separately, enabling both precision and flexibility simultaneously.
Solution Approach 2:
The system dynamically adjusts access control based on multiple variables including time of day, user identity, content ratings, and accumulated viewing time. Restrictions are not static but adapt dynamically to different conditions, allowing the system to be both precise in its control and flexible in its response to varying situations.
2Reliability
If comprehensive access restrictions are implemented, then content appropriateness is controlled, but system complexity increases
Solution Approach 1:
The access control application serves multiple functions within a single unified system: it performs authentication, enforces channel blocking, applies rating-based restrictions, tracks viewing time, and manages monetary charges. This multi-functionality reduces overall system complexity by consolidating what would otherwise require separate systems for each function.
Solution Approach 2:
The patent implements nested layers of access control where multiple restriction types can be applied simultaneously and hierarchically. For example, a time-based restriction can contain rating-based restrictions within it, which in turn can contain channel blocking rules. This nested structure organizes complexity in a manageable way while maintaining comprehensive control.
3Measurement precision
If authentication sequences are required, then user differentiation is achieved, but operation time increases
Solution Approach 1:
The system performs authentication and user identification in advance, during the initial access attempt, so that subsequent content access can be quickly granted or denied based on pre-determined restrictions. This preliminary action ensures precise user differentiation while minimizing time loss during actual content consumption.
Solution Approach 2:
The authentication system allows users to self-identify and self-authenticate through simple input mechanisms, reducing the need for manual verification by operators. This self-service approach maintains precise user identification while minimizing the time required for authentication.

AI summary
A disclosed method of enabling a subscriber to control access to multimedia content received from a multimedia distribution network includes provisioning the network with an access control application. The application is operable to respond to an invocation by a member of a subscriber class by enabling at least one subscriber class function, wherein the subscriber class function enables the subscriber class member to define an access restriction for members of a controlled class. The application responds to an invocation by a member of the controlled class by enabling the controlled class member to access content not subject to the defined restrictions permitting the controlled class member to define preferences from content not subject to the defined restrictions. The definable preferences may include TV channel preferences and interactive games preferences. Restrictions may be defined based on channel identification, a rating associated with requested content, an elapsed viewing time, and a monetary charge.
