Network Redirection Device for Remote Media Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media content delivery methods do not efficiently redirect media content from a subscriber's local receiving device to their remote rendering device, such as a smartphone, especially when the user is outside the local rendering area, leading to unavailability of ongoing media content due to separate data plans and service agreements.
Innovation Solution
A network redirection device that identifies the location of the rendering device and redirects the media content signal from the local receiving device to the remote rendering device via an independent connection, using a placeshifted output interface when the device is outside the local media network, allowing seamless continuation of media playback across different service areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If media content is transmitted directly to mobile device via 3G/4G cellular network, then media content is available on mobile device, but separate data plan fees are incurred and service continuity is disrupted when moving between service areas
Solution Approach 1:
The patent introduces a redirection device as an intermediary component that sits between the content delivery network and the mobile rendering device. This redirection device receives media content from the CDN and forwards it to the mobile device, allowing the mobile device to access content already received by the fixed receiving device without incurring separate data plan fees. The intermediary enables service continuity across different service areas by routing content through the fixed receiving device's existing service agreement.
2Ease of operation
If rendering device remains in local rendering area, then service agreement with cable provider is maintained, but user cannot access media content when outside local rendering area
Solution Approach 1:
The patent extends the service coverage from the local rendering area (spatial dimension) to remote locations by introducing a network-based delivery path. The redirection device enables media content to be delivered to mobile devices at any location with network connectivity, transforming the service model from location-bound to network-bound, thereby adding a new dimension of service accessibility.
3Reliability
If separate transmission of media content from content provider is used for each device, then each device receives content independently, but cost and complexity increase with multiple service agreements
Solution Approach 1:
The patent merges the content delivery paths for fixed and mobile devices by using the same service agreement with the cable provider. The redirection device consolidates the delivery mechanism, allowing a single service agreement to support both fixed receiving devices and mobile rendering devices. This eliminates the need for separate service agreements and reduces the complexity of managing multiple subscriptions while maintaining reliable content delivery to all devices.

AI summary
A redirection device for remote streaming media reroutes media content sent to the receiving device, typically located in the home of the subscriber, to the subscriber's mobile device such as a laptop or smartphone. Remote media streaming provides media recipients with capabilities for out-of-home (OOH) viewing for remotely rendering media content from a subscriber based receiving device to a personal electronic device. The remote streaming redirects media that has already been received by the subscription based receiving device, such that the redirection device forwards a rendering signal including the requested content to the rendering device based on the reported location. The redirected media stream therefore emanates from the redirection device as an independent transmission of content already received by the receiving device, and not as a separate transmission of media content from the content provider.
