Host-Specific Files for Cable Set-Top Box Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable television systems face challenges in efficiently provisioning new or enhanced services due to compatibility issues between conditional access modules and host devices, limiting the ability to introduce innovative service capabilities without coordinating with multiple vendors and requiring frequent upgrades of conditional access modules.
Innovation Solution
The implementation of host-specific files and protocols allows for the configuration of enhanced services on set-top boxes, enabling new capabilities without modifying existing infrastructure, and allowing different host manufacturers to develop and market devices with unique messaging protocols, while maintaining compatibility with legacy systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If host-specific files and protocols are implemented to enable flexible service provisioning, then adaptability and ease of operation are improved, but device complexity increases due to support for multiple messaging protocols and host-specific configurations
Solution Approach 1:
The patent segments the service provisioning system into host-specific components and core cable system components. Host-specific files contain protocol messages and descriptive information tailored to specific host models, allowing the core cable system to remain unchanged while supporting multiple host types through modular, segmented configuration data
Solution Approach 2:
The patent introduces host-specific files as an intermediary layer between the cable system and diverse host devices. These files act as a mediator that translates and adapts messaging protocols, allowing the cable system to communicate with different host manufacturers' devices without requiring direct integration or coordination with each vendor
2Reliability
If legacy systems are maintained without modification to preserve stability, then reliability is improved, but adaptability deteriorates as new service capabilities cannot be introduced
Solution Approach 1:
The patent applies preliminary action by pre-configuring host-specific files with all necessary protocol messages and descriptive information for specific host models before deployment. This allows new service capabilities to be introduced through pre-prepared configuration data rather than requiring system modifications or coordination with host manufacturers at the time of service introduction
Solution Approach 2:
The patent uses copying by distributing host-specific files that contain replicated protocol messages and descriptive information tailored to specific host models. These files are copied and deployed to relevant systems, allowing the same core cable system to support multiple host types through copied and adapted configuration data rather than modifying the core system
3Manufacturing precision
If coordination with multiple vendors is required for service provisioning, then manufacturing precision is improved through standardized interfaces, but productivity deteriorates due to increased complexity in vendor coordination
Solution Approach 1:
The patent enables self-service by allowing each host manufacturer to independently create and provide their own host-specific files containing protocol messages and descriptive information. This eliminates the need for the cable system operator to coordinate with multiple vendors for service provisioning, as each vendor can autonomously prepare their host-specific configuration files
Data Source
AI summary
Flexible systems and methods are disclosed that may be used for provisioning, configuring, and controlling a host embodied in a cable set top box or other digital device attached to a digital communication network, such as cable distribution network. An enhanced services system maintains various host files for various types of hosts that a cable subscriber may purchase and connect to the cable network. The Enhanced Services Server interacts with the host using the host files. The host files may be downloaded from the host manufacturer into a database that distributes the modules as required to the various enhanced services systems. The host may be purchased by the cable subscriber and provisioning may be initiated by the retailer at the time of purchase using a provisioning network interacting with the appropriate cable system serving the subscriber.
