Managed Network HD3D Streaming with QoS Bandwidth Reservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high bandwidth requirements for full high-definition (HD) resolution stereoscopic video present a challenge for service providers to deliver 3DTV to consumers in a video-on-demand environment, as it consumes significantly more bandwidth than traditional 2D video, making it difficult to support premium TV viewing experiences.
Innovation Solution
A system and method for providing full HD resolution stereoscopic video through a managed content delivery network with quality of service (QoS) control, which includes receiving user selections, reserving bandwidth, and streaming HD3D content over a managed network, allowing users to request and receive HD3D content via a broadband or Internet connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If full HD resolution stereoscopic video is delivered, then video quality is improved, but bandwidth consumption increases significantly
Solution Approach 1:
The patent segments the stereoscopic video delivery into two distinct paths: a managed content delivery network for high-quality HD3D content with guaranteed bandwidth, and a public network for standard definition content. This segmentation allows each path to be optimized for its specific requirements, resolving the contradiction between high video quality and bandwidth consumption by directing traffic appropriately.
Solution Approach 2:
The patent introduces a managed content delivery network as an intermediary between the content source and the user device. This intermediary network provides QoS controls and bandwidth guarantees specifically for HD3D content, enabling high-quality delivery without overburdening the public network infrastructure.
2Reliability
If bandwidth is reserved for HD3D content, then QoS control is improved, but network resource allocation becomes more complex
Solution Approach 1:
The patent segments network resource allocation into managed resources within the content delivery network and unmanaged resources in the public network. By confining QoS controls and bandwidth reservations to the managed portion only, the system achieves reliable service delivery without imposing complex resource management requirements on the entire network infrastructure.
3Ease of operation
If users can select and purchase content over broadband, then ease of operation is improved, but network management complexity increases
Solution Approach 1:
The patent segments the user experience into content selection/browsing functions that operate over the public broadband network, and content delivery functions that occur over the managed content delivery network. This allows users to easily select and purchase content using standard internet protocols while the complex QoS management and bandwidth reservation are handled separately in the managed network portion.
Data Source
AI summary
A method performed by one or more computing devices includes receiving, by a data center and from a user device via a public network connection, a selection of high-definition three-dimensional (HD3D) content and sending, by the data center and to the user device, a link to a content delivery system to provide the selected HD3D content. The method also includes receiving, by the content delivery system and from the user device, a streaming request for the selected HD3D content; reserving, by the content delivery system, bandwidth, for the selected HD3D content, within a managed network; and sending, by the content delivery system and to the user device, a streaming Internet protocol (IP) address for providing the selected HD3D content over the managed network.
