5G Media Content Steering Across Trusted and External Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G media streaming architecture lacks support for content steering and specific deployment scenarios for uplink and downlink media streaming, particularly in video coding technology, as defined by 3GPP TS 26.501 and ETSI TS 103 998.
Innovation Solution
A method for video decoding, encoding, and processing using a trusted distribution network (DN) of a mobile network operator (MNO) to generate, obtain, and stream content to user equipment (UE) based on a presentation manifest, utilizing 5G Media Downlink Streaming (5GMSd) instances and content steering directed by steering servers.

Engineering Contradiction Analysis
1Adaptability or versatility
If the 5G media streaming architecture follows the general architecture defined in 3GPP TS 26.501, then the system maintains broad compatibility and general functionality, but it lacks support for content steering and specific deployment scenarios for uplink and downlink media streaming
Solution Approach 1:
The patent segments the 5G media streaming architecture into distinct functional components: a steering server for content steering decisions, distribution networks for content delivery, and client devices for consumption. This segmentation allows content steering functionality to be added without redesigning the entire architecture, thus improving adaptability while managing complexity through modular design.
Solution Approach 2:
The patent introduces a steering server as an intermediary component between the content source and the client device. This mediator receives content requests, makes steering decisions based on network conditions and device capabilities, and directs content flow through appropriate distribution networks. The intermediary approach enables content steering functionality without requiring changes to existing 3GPP architecture components.
2Adaptability or versatility
If video content is delivered to user equipment with varying computational resources, then the system supports both AR and non-AR devices, but the processing load and energy consumption vary significantly across devices
Solution Approach 1:
The patent applies local quality by rendering video content at edge computing locations closer to client devices rather than requiring all devices to perform full rendering locally. The steering server assesses device capabilities and directs rendering tasks to appropriate edge servers for devices with limited computational resources, while allowing capable devices to handle rendering locally. This ensures consistent content quality across different device types while optimizing energy consumption based on local device characteristics.
3Productivity
If content is streamed through multiple distribution networks including external DNs, then the system provides flexible content delivery paths, but the coordination and management of multiple networks increases system complexity
Solution Approach 1:
The patent merges the functionality of multiple distribution networks under a unified steering server that manages content delivery across trusted and external distribution networks. The steering server consolidates network selection, content routing, and quality of service management into a single control point, enabling efficient content delivery through multiple networks while reducing the coordination complexity that would otherwise be distributed across all network elements.

AI summary
There is provided a method and apparatus including computer code to cause a processor or processors to generate, by a trusted distribution network of a mobile network operator (MNO), at least one 5G Media Downlink Streaming instance configured to deliver at least part of a content to a user equipment including a 5GMSd-aware application and a 5GMSd client, the at least part of the content comprising video data, obtain obtaining, by the trusted DN, a presentation manifest published by a 5GMSd Application Provider of an external DN that is external to both the trusted DN and the UE, and perform a conversion, between a visual media file of the content and a bitstream of a visual media data of the content according to a format rule, and at least one of streaming the content to the UE and playing the content by the UE based on the conversion.
