Network DVR Playback Adapter for Legacy Set-Top Box Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital video recorders (DVRs) and set-top boxes (STBs) are often incompatible with modern digital content delivery networks, limiting their ability to receive and play back digital content stored in cloud services, which can lead to compatibility issues and reduced user experience.
Innovation Solution
A network-based digital video recording playback adapter that retrieves digital content from cloud storage, processes it, and transmits it to legacy STBs, using a system comprising nDVR storage arrays, DRM keystores, content delivery networks, and home gateways to ensure compatibility and seamless playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional DVRs and STBs are used, then existing hardware can be maintained, but compatibility with modern digital content delivery networks is lost
Solution Approach 1:
A gateway device is introduced as an intermediary between the legacy DVR/STB and the digital content delivery network. The gateway receives content from the network, processes it into appropriate formats, and delivers it to the legacy device, enabling compatibility without modifying the legacy hardware itself.
Solution Approach 2:
The system is divided into separate functional components: the legacy DVR/STB remains unchanged while the gateway handles content reception, processing, and delivery. This segmentation allows the legacy device to maintain its existing functionality while the gateway provides the necessary adaptation to modern network protocols.
2Quantity of substance
If cloud storage is used, then storage capacity is increased, but access to content by legacy devices is restricted
Solution Approach 1:
The gateway acts as a mediator that retrieves content from cloud storage and transforms it into a format that legacy devices can process and display, thereby enabling access to cloud-stored content without requiring the legacy device to have direct cloud access capabilities.
Solution Approach 2:
The gateway changes the parameters of the content data by converting it from cloud storage formats into legacy device-compatible formats, including appropriate video codecs, resolution, and protocol formats, enabling the legacy device to process the content.
3Adaptability or versatility
If content is delivered through the gateway, then legacy device compatibility is maintained, but system complexity increases
Solution Approach 1:
The gateway is designed with multi-functionality to handle multiple tasks: receiving content from the digital content delivery network, processing and converting content formats, managing DRM rights, and delivering content to various legacy devices. This consolidation of functions into a single device manages system complexity while maintaining compatibility.
4Reliability
If DRM protection is implemented, then content security is improved, but processing requirements increase
Solution Approach 1:
DRM rights information is obtained and processed in advance by the gateway before content delivery. The gateway retrieves rights information from the digital rights management system, processes the DRM protection parameters, and prepares the authorized content for delivery, reducing the processing burden during actual content playback.

AI summary
This disclosure describes systems and methods related to a network-based digital video recorder playback adapter. In some embodiments, a request for digital content may be received from a customer device. A plurality of segments associated with the digital content may be received. A content stream may be generated based at least in part on the plurality of segments associated with the digital content. The content stream may be transmitted. Additionally, load balancing may be implemented to optimally select a source of digital content. Additional load balancing may further be performed at a customer premises between multiple communicative connections to provide requested content to the client device.
