Local Proxy Server Manifest Editing for Streaming Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing streaming content playback solutions waste resources by repeatedly selecting adaptive tracks and lack caching and preloading mechanisms, leading to inefficient data usage and slowed execution speeds.
Innovation Solution
Implementing a local streaming server to set an initial bit rate for streaming content playback, optimizing track selection by editing manifest files to prioritize tracks based on set bit rates, and preloading and caching content in a listview based on relative positions, using a local proxy server to enhance caching efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the client selects the first track from the manifest file without bit rate awareness, then the track selection process is simple, but the client has to select adaptive tracks again in subsequent requests causing resource waste
Solution Approach 1:
The patent applies preliminary action by having the client determine and store its own bit rate capability in advance before track selection. The client calculates its bit rate based on network conditions and device capabilities beforehand, then uses this pre-determined bit rate information to directly select the appropriate track without needing to repeatedly query or adapt tracks in subsequent requests, thereby avoiding resource waste.
2Measurement precision
If the client implements adaptive track selection algorithms considering network bandwidth and buffer, then track selection accuracy is improved, but the complexity of the client increases
Solution Approach 1:
The patent applies self-service by enabling the client to autonomously determine its own bit rate capability based on its network conditions and device characteristics without requiring complex external algorithms or server interventions. The client independently calculates its bit rate and uses this self-determined information to make track selection decisions, simplifying the overall system complexity while maintaining accurate track selection.
3Device complexity
If no caching mechanism is implemented for video fragment files, then the system is simple, but data waste and execution speed loss occur when streaming content is focused in the content listview
Solution Approach 1:
The patent applies preliminary action by implementing a caching mechanism that pre-loads and stores video fragment files before they are actually needed for playback. When a user focuses on content in the listview, the system can quickly retrieve pre-cached fragment files instead of downloading them from scratch, significantly improving execution speed. The cache stores frequently accessed fragment files to prepare them in advance for rapid retrieval.

AI summary
A method for playing back streaming content according to an embodiment may include a step in which a streaming player client sets an initial bitrate for a player module playing back streaming content; a step in which the streaming player client delivers, from the player module to a streaming server, a manifest file request for the streaming content; a step in which a local proxy server edits the manifest file delivered from the streaming server, the manifest file being edited on the basis of the set initial bitrate; and a step in which the local proxy server delivers the edited manifest file to the player module through the streaming player client.
