Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for content delivery over networks face challenges in integrating disparate services and equipment, leading to economic inefficiencies and limited interoperability, with inadequate control over content distribution and protection, which hampers the release of new content due to unauthorized access and reproduction concerns.
Innovation Solution
A network apparatus and method for provisioning consumer premises equipment (CPE) with secure software and cryptographic keys, enabling seamless integration of downloadable conditional access, digital rights management, and trusted domains, allowing for remote configuration and management of client devices to ensure secure content delivery across various delivery paradigms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple disparate services and equipment are integrated in a network, then service functionality is improved, but system complexity and interoperability difficulties increase
Solution Approach 1:
The patent implements a universal provisioning system that can handle multiple CA systems, digital rights management, and trusted domains through a single integrated platform. The system uses standardized interfaces and protocols to manage diverse services (broadcast, VOD, PVR, Internet access, telephony) uniformly, eliminating the need for separate provisioning mechanisms for each service type.
Solution Approach 2:
The provisioning system acts as an intermediary between the network infrastructure and client devices, translating between different service requirements and device capabilities. It mediates the integration of disparate equipment by providing a common configuration and management layer that handles interoperability issues centrally.
2Reliability
If content distribution control is strengthened to prevent unauthorized access, then content protection is improved, but device provisioning and service deployment become more difficult
Solution Approach 1:
The system performs preliminary provisioning and configuration of security parameters before content delivery begins. Client devices are pre-configured with appropriate security credentials, encryption keys, and access rights through automated provisioning processes, so that content protection is already in place before any content distribution occurs.
Solution Approach 2:
The provisioning system enables client devices to self-configure with appropriate security settings and credentials. Devices automatically receive and apply security configurations, encryption parameters, and access control policies without requiring manual security setup, thereby maintaining strong content protection while simplifying deployment.
3Manufacturing precision
If manual provisioning of CPE devices is used, then configuration accuracy is improved, but provisioning time and operational efficiency deteriorate
Solution Approach 1:
Client devices automatically perform self-provisioning by communicating with the provisioning system to obtain configuration parameters, security credentials, and service settings. The devices self-configure based on received provisioning data, eliminating manual configuration steps while maintaining accuracy through standardized provisioning protocols and validated configuration templates.
Solution Approach 2:
The provisioning system prepares and validates configuration parameters before deploying them to client devices. Configuration templates and security parameters are pre-configured and verified for correctness, ensuring that when devices receive provisioning data, the configuration is already optimized for accuracy and requires minimal manual intervention.
4Reliability
If secure software and cryptographic keys are distributed to client devices, then content security is improved, but network bandwidth consumption and provisioning complexity increase
Solution Approach 1:
The provisioning system divides security software and cryptographic parameters into modular components that can be selectively distributed. Instead of transmitting complete security suites to all devices, the system segments security functionality and delivers only the specific cryptographic keys and software modules required for each device's intended content access rights, reducing unnecessary bandwidth consumption.
Data Source
AI summary
Apparatus and methods for provisioning of customer premise equipment (CPE) equipped with a secure microprocessor to receive e.g., digital video content by entering unique identification of the CPE at one or more servers located at the headend or other location of a content-based network. In one embodiment, the CPE comprises a download-enabled (e.g., DCAS) host with embedded cable modem and embedded set-top box functionality, and the provisioning includes enabling DOCSIS functionality of the CPE, assigning an IP address to the CPE and providing the CPE with a client image for the conditional access system chosen by the network operator. In one variant, the network operator can deactivate a provisioned device while connected to the network, as well when disconnected from the network. The network operator can also add, delete or replace conditional access client image in a provisioned device.
