Display Adapter for Decoding Encoded Video on User Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face limitations in accessing television content on devices other than traditional set-top boxes, as these devices lack the capability to decode television content and fail to provide interactive experiences while watching TV.
Innovation Solution
A system that enables television service providers to deliver encoded video content to various user devices, allowing them to display TV programming on devices like smartphones, tablets, and gaming systems, using a network as an interconnected control and bearer plane between application platforms and user device displays, with display adapters registering and managing content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If television content is delivered through traditional set-top boxes, then content delivery is reliable and controlled, but consumer flexibility to view content on multiple devices is limited
Solution Approach 1:
The system separates the set-top box functionality into two independent components: a head-end component that handles content delivery and a client component that runs on user devices. This segmentation allows content to be delivered to multiple devices without requiring multiple set-top boxes, thereby improving device flexibility while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The display adapter client component is designed to run on various user devices (smartphones, tablets, PCs, gaming systems) providing universal access to television content. This multi-functionality approach allows a single content delivery system to serve multiple device types, enhancing adaptability without proportionally increasing system complexity.
2Adaptability or versatility
If set-top boxes perform all decoding functions, then content security is maintained, but other devices cannot display television content
Solution Approach 1:
The display adapter client acts as an intermediary component that bridges the head-end content delivery system and various user devices. It receives encoded content from the head-end, performs decoding locally on the user device, and renders the content. This intermediary approach maintains content security by keeping the decoding logic controlled while enabling broad device compatibility.
Solution Approach 2:
The system changes the operational parameters of content delivery by transmitting encoded content instead of decoded video signals. This parameter change allows content to be securely transmitted over networks to multiple devices, with decoding performed only at the client component on authorized devices, thereby improving device compatibility while maintaining content security through encryption and authorized decoding.
3Ease of operation
If television is used as a traditional display device, then video output is simple, but interactive functionality is limited
Solution Approach 1:
The system inverts the traditional television architecture by placing the intelligent processing component (display adapter client) on the user device rather than on the television itself. The television becomes a simple display output device, while the interactive control functionality resides on the user's smartphone, tablet, or PC. This inversion enables rich interactive functionality through the user device's operating system and applications while keeping the television's role simple.

AI summary
A device receives, from a user device, a request to subscribe to a video content service, and receives privileges and a list of authorized users associated with the user device. The device also registers the user device based on the request to subscribe and based on the privileges associated with the user device, and receives a request to register applications associated with the user device. The device further registers, based on the request to register, the applications associated with the user device, and provides, to the user device, at least one registered display adapter that is capable of being used by the user device to display encoded video content.
