TV Display Control via Dynamic Secure Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital television decoder solutions are inflexible and restrictive, failing to adapt to changing service offerings and 'over the top' models, where operators are not involved in access to services, and do not allow dynamic addition or modification of operators or services, nor do they support hybrid operations or synchronization with connected devices.
Innovation Solution
A method for controlling the display of multimedia data on a TV that includes a secure software application for infographic customization and dynamic connector opening, using a unique identifier recorded in the TV's memory, allowing for independent manufacture and supply from operators, and enabling dynamic service offerings through an external database, with bidirectional dialogue between the TV and platform for secure configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration data is pre-programmed into the decoder's memory during manufacturing, then the decoder can operate with a specific operator, but the system cannot adapt to rapid service changes or add operators dynamically
Solution Approach 1:
The patent transforms the static, pre-programmed configuration into a dynamic system where configuration data can be updated remotely. The decoder receives configuration files via communication interfaces (HDMI, USB, network) that contain operator identifiers and service parameters, allowing the system to adapt to changing service offerings and add operators without remanufacturing the decoder.
Solution Approach 2:
The patent pre-establishes the decoder's capability to receive and process configuration files during manufacturing, but the actual operator-specific configuration is applied later through external means. This allows the hardware to be manufactured generically while the software configuration is customized post-deployment, resolving the contradiction between manufacturing efficiency and operational flexibility.
2Reliability
If the decoder is restricted to a single operator through program memory lock, then security is maintained, but the system cannot support hybrid operation or over-the-top services
Solution Approach 1:
The patent makes the decoder universal by removing operator-specific restrictions and enabling it to work with multiple operators and service models. The configuration file mechanism allows the same decoder hardware to support traditional operator-managed services, over-the-top services, and hybrid models by simply changing the configuration data, not the hardware.
Solution Approach 2:
The patent changes the operational parameters of the decoder through configuration files that contain operator identifiers, service URLs, and access control settings. By modifying these parameters remotely, the decoder can switch between different operational modes (operator-managed, over-the-top, hybrid) without physical reconfiguration or manufacturing changes.
3Ease of manufacture
If the decoder uses pre-recorded operator lists, then manufacturing is simplified, but the system cannot synchronize with connected devices or support rapid service developments
Solution Approach 1:
The patent extracts the operator configuration data from the manufacturing process and places it in external configuration files that can be updated independently. This separation allows mass production of generic decoders while enabling rapid deployment of new services by simply distributing updated configuration files, without requiring complex manufacturing processes.
4Adaptability or versatility
If the system allows dynamic addition of operators, then service flexibility improves, but security risks from unauthorized access increase
Solution Approach 1:
The patent implements a feedback mechanism where the decoder communicates with external servers or connected devices to verify operator authorization before accepting configuration updates. The system receives authentication tokens or certificates that validate the legitimacy of configuration changes, ensuring that only authorized operators can add or modify service parameters.
Solution Approach 2:
The patent introduces an intermediary authentication layer (configuration files with digital signatures, SSL certificates, or token-based authentication) that mediates between the dynamic configuration updates and the security requirements. This intermediary verifies the legitimacy of operator additions without preventing dynamic service deployment.
