Content Preparation Template for 5G Media Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G media streaming technologies lack a defined format for content preparation templates, which are essential for processing and streaming media content effectively, as defined by 3GPP TS26.512, but do not specify how to structure these templates for input and output characteristics and encoding parameters.
Innovation Solution
A method and system for content preparation in a 5G media streaming network that involves receiving content, a content preparation template specifying input and output Common Media Application Format (CMAF) track characteristics, and encoding parameters, and preparing the content according to these specifications for streaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If content preparation templates are used to define processing parameters, then content preparation efficiency is improved, but the lack of a defined format for templates causes processing errors and incompatibility
Solution Approach 1:
The patent applies parameter changes by defining a standardized format for content preparation templates that includes specific parameters such as input track characteristics, output track characteristics, and encoding parameters. This standardization transforms the undefined template structure into a well-defined parameter set, ensuring both efficiency and compatibility across different 5GMS network implementations.
2Manufacturing precision
If detailed encoding parameters are specified for multiple output tracks, then output quality is improved, but template complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the content preparation template into distinct segments: input track characteristics, output track characteristics, and encoding parameters. Each segment is further divided into specific parameters (e.g., resolution, bitrate, codec type). This segmentation allows detailed specification of output quality without creating an monolithic complex structure, as each parameter can be independently configured and managed.
