Localized Media Fragment Streaming via Playlist Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for delivering video media to multiple territories require creating multiple versions with localized content, resulting in a cumbersome and costly process due to the need for complete audio, video, and subtitle files, which complicates management and distribution.
Innovation Solution
The system delivers localized media content by streaming fragments of a base file and localized file to a content playback device, using a web server to dynamically stream or pre-deliver these fragments based on a playlist that determines the order of playback, potentially residing on a web server or the playback device, and can include a content delivery network for optimized delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple complete versions of media files are created for different territories, then localized content requirements are met, but file management complexity and distribution costs increase significantly
Solution Approach 1:
The patent segments media files into modular components: a base file containing common content and localized files containing territory-specific content. This segmentation allows the system to deliver only necessary fragments rather than complete duplicate files, reducing management complexity while maintaining adaptability to different localization requirements
Solution Approach 2:
The base file serves multiple territories universally, containing content that is common across all regions. This universal component reduces redundancy and simplifies management, while the modular structure allows the same base file to be combined with different localized files to meet diverse localization needs
2Adaptability or versatility
If multiple complete versions of media files are created for different territories, then localized content requirements are met, but distribution costs increase
Solution Approach 1:
By segmenting media into base and localized components, the system reduces the total quantity of files that need to be distributed. Instead of sending complete duplicate files to each territory, only specific localized fragments are transmitted, significantly reducing distribution volume while maintaining full localization capability
Solution Approach 2:
The system merges the universal base file with specific localized files to create the final localized media experience. This combining approach allows distribution of a shared core content across all territories, with only incremental localized additions, reducing overall distribution requirements
3Reliability
If complete media files are delivered to playback devices, then all content is available for playback, but streaming latency increases
Solution Approach 1:
The patent segments media delivery into targeted fragments rather than complete files. The playback device receives only the specific base and localized fragments needed for the requested content, enabling faster delivery and reduced latency while ensuring all necessary content is available for reliable playback
Solution Approach 2:
The system performs preliminary actions by pre-positioning base files and localized files on servers before playback requests. When a user requests localized content, the system can quickly assemble and stream the specific fragments needed without waiting for complete file transfers, reducing latency while maintaining content availability
Data Source
AI summary
Systems and methods for delivery of localized media assets to a content playback device are disclosed. A file server stores a base file and localized file associated with a localized media content. The base file and localized file each include one or more fragments. A web server delivers base file fragments and localized file fragments from the file server to the content playback device. Playback logic contained in one or more playlists determines an order of streaming each of the plurality of base file fragments and each of the plurality of localized file fragments for playback of the localized media content.
