Streaming Media Intro Caching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Streaming media technologies face inefficiencies due to the repeated download of common introductory scenes in media content, leading to increased bandwidth usage and battery life consumption on client devices, which delays the download of the remainder of the media content and affects user experience.
Innovation Solution
Implementing a system that identifies and caches common introductory sequences on client devices before media playback, allowing for seamless playback by retrieving pre-fetched intro content from local storage while streaming the rest of the content from the server, and potentially sharing cached content between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If common introductory scenes are re-streamed for each video playback, then complete video content can be delivered, but bandwidth usage increases and battery life is consumed
Solution Approach 1:
The system performs preliminary action by identifying and caching common introductory scenes from multiple videos before they are needed. When a user requests a video, the cached intro scene is already available for immediate playback, eliminating the need to re-stream it and thus reducing bandwidth usage and energy consumption.
Solution Approach 2:
The system merges multiple video streams by extracting and combining their common introductory scenes into a single cached copy. This consolidation allows the same intro content to be reused across multiple videos, reducing redundant data transmission and saving bandwidth.
2Reliability
If common introductory scenes are re-downloaded for each video, then all video content can be accessed, but loading time increases
Solution Approach 1:
The system performs preliminary action by pre-fetching and caching common introductory scenes before user requests. This advance preparation ensures that when users request videos, the intro content is already stored and ready for immediate playback, significantly reducing loading time.
3Loss of energy
If introductory scenes are cached on client devices, then bandwidth usage is reduced, but device storage is consumed
Solution Approach 1:
The system applies local quality by caching content at the edge (client devices or CDN nodes) rather than centrally. This distributed caching approach stores intro scenes locally where they are most needed, reducing bandwidth usage while managing storage efficiently across multiple locations rather than concentrating it in one place.
4Ease of operation
If streaming technology is used for on-demand video, then user convenience is improved, but repeated downloads of intro content waste resources
Solution Approach 1:
The system performs preliminary action by identifying and caching common introductory scenes from multiple videos before user requests. This advance preparation ensures that when users request videos, the intro content is already stored and ready for immediate playback, significantly reducing loading time.
Data Source
AI summary
A method for reducing bandwidth needed for streaming media content. The method includes identifying, by the streaming media server, a subset of a plurality of media content items having a portion of media data in common and extracting, by the streaming media server, the common portion from a first media content item of the subset; generating, by the streaming media server, a common media package comprising the extracted common portion, providing, by the streaming media server to a client media device, the common media package, and receiving, by the streaming media server from the client media device, a request for an item of content. The method also includes selecting an item of content from the subset; and transmitting, by the streaming media server to the client media device, an identification of the common media package and an identification of a chunk of the selected item of content subsequent to the common portion.
