Solution Overview
Problem
Current media processing systems, particularly in mobile devices, face challenges in handling the increasing computational demands of new services and applications due to limited processing capabilities, necessitating improved methods for configuring and deploying media processing in networks.
Innovation Solution
The implementation of Network-Based Media Processing (NBMP) architecture, which allows devices to request network/cloud entities for media processing by sending a workflow description document, enabling the setup of cloud resources for processing and routing media data/metadata, and the integration of Flexible Live Uplink Streaming (FLUS) services to manage media workflows efficiently across core and edge networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If media processing is performed on mobile devices, then processing capability is limited, but device complexity and power consumption increase
Solution Approach 1:
The patent extracts media processing functions from mobile devices and relocates them to network-based media processing entities. The mobile device sends media data to external processing entities through the network, thereby reducing local processing requirements and device complexity while maintaining enhanced media processing capabilities.
Solution Approach 2:
The patent introduces network-based media processing entities as intermediaries between mobile devices and media processing resources. These entities receive media data from devices, perform complex processing operations, and return processed results, thereby enabling advanced media processing without increasing device complexity.
2Power
If compute capacity is deployed at the core network, then processing power is centralized, but latency and throughput for media streaming deteriorate
Solution Approach 1:
The patent deploys media processing entities at multiple locations within the network infrastructure, including edge networks and content delivery networks, rather than solely at the core network. This distributed deployment reduces the distance media data must travel, thereby lowering latency and improving throughput while maintaining centralized management and coordination.
3Power
If cloud resources are used for media processing, then compute capacity increases, but network bandwidth and data transmission requirements increase
Solution Approach 1:
The patent segments media processing into multiple stages and distributes them across different network entities. Some processing is performed at the edge network, some at content delivery networks, and some at the core network. This segmentation reduces the amount of data that needs to be transmitted over the entire network path, thereby reducing overall bandwidth requirements while maintaining access to cloud computing resources.
