Hierarchical Multimedia Streaming Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multimedia streaming technologies offer limited interactive viewing options, as they provide a linear experience that does not account for the complex structure of multimedia content, such as multiple scenes and shots, which can result in suboptimal compression and viewing experiences.
Innovation Solution
The described techniques involve determining the hierarchical structure of multimedia content based on production stage information, allowing for adaptive compression and segmentation of content into segments based on scene and shot characteristics, enabling flexible viewing options and improved compression efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If linear viewing experience is provided for multimedia content, then simplicity of streaming delivery is maintained, but viewing options and interactivity are limited
Solution Approach 1:
The multimedia content is segmented into multiple versions based on the hierarchical structure of scenes and shots. Each version corresponds to different storylines or perspectives, allowing viewers to select among multiple viewing options while maintaining streamlined delivery through structured segmentation.
Solution Approach 2:
The patent introduces a new dimension of interactivity by allowing viewers to navigate through different storylines and perspectives within the same content. This transforms the traditional linear viewing experience into a multi-dimensional interactive experience where users can explore various narrative paths.
2Ease of manufacture
If uniform compression is applied to multimedia content, then processing simplicity is maintained, but compression efficiency is suboptimal
Solution Approach 1:
Different compression levels are applied to different segments of the multimedia content based on their specific characteristics. High-motion scenes receive higher compression ratios while low-motion scenes use lower compression ratios, optimizing overall compression efficiency while maintaining quality where needed.
Solution Approach 2:
The compression strategy dynamically adapts to the characteristics of each scene and shot within the multimedia content. The system automatically adjusts compression parameters based on motion detection, scene complexity, and visual importance, transforming static uniform compression into dynamic adaptive compression.
3Productivity
If content is divided into fixed segments, then distribution efficiency is improved, but viewing flexibility is reduced
Solution Approach 1:
Content is segmented according to the natural hierarchical structure of scenes and shots rather than fixed time intervals. This allows the segmentation to align with narrative boundaries and visual transitions, improving both distribution efficiency through structured organization and viewing flexibility by enabling navigation at meaningful content boundaries.
Solution Approach 2:
The segmented content structure serves multiple functions simultaneously: it enables efficient distribution through organized file structures, supports adaptive streaming by providing multiple resolution versions, and facilitates interactive viewing by allowing users to navigate between different storylines and perspectives within the same segmented framework.

AI summary
Methods, apparatus and systems related to packaging a multimedia content for distribution are described. In one example aspect, a method includes receiving media files comprising video or audio data captured at a production stage and determining a hierarchical structure of the multimedia content based on production stage information of the multimedia content. The hierarchical structure indicates that the multimedia content comprises multiple scenes, each of which comprises multiple shots produced with corresponding devices and cast. The method also includes identifying characteristics associated with the individual scenes based on the production stage information, generating multiple copies of the multimedia content at different compression levels, and dividing each of the multiple copies of the multimedia content into segments based on the hierarchical structure. The compression levels and a length of a segment are adaptively adjusted based on the characteristics associated with the individual scenes.
