Multimedia Redirection Server Metadata Resumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia redirection technologies fail to automatically resume playback of multimedia content that was not closed before a user's last disconnection, leading to inconvenient blank or black screens when the user logs in again, affecting the user experience.
Innovation Solution
A method and system that automatically store metadata of multimedia instances not shut down during disconnection, allowing the server to retrieve and send this metadata to the client upon reconnection, enabling the client to resume playback of the multimedia content from the previous state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If multimedia redirection is implemented to reduce server CPU usage and network bandwidth occupation, then server resource consumption is reduced, but multimedia playback cannot be automatically resumed after user disconnection and reconnection
Solution Approach 1:
The server performs preliminary actions by storing metadata of multimedia instances before user disconnection occurs. When the user reconnects, the server retrieves this pre-stored metadata to automatically resume playback, eliminating the need for manual intervention and ensuring continuous playback experience while maintaining the redirection architecture's resource efficiency
Solution Approach 2:
The system establishes a feedback mechanism where the server monitors user disconnection and reconnection events. Upon detecting reconnection, the server queries stored metadata and triggers automatic playback resumption, creating a closed-loop control that maintains playback continuity without compromising the resource-saving redirection approach
2Reliability
If multimedia playback state is automatically resumed after reconnection, then user experience and playback continuity are improved, but server storage and metadata management complexity increase
Solution Approach 1:
The system extracts only the essential metadata required for playback resumption (multimedia instance identifiers, playback position, format information) from the complete multimedia data. This selective extraction minimizes storage requirements and simplifies metadata management on the server while still enabling full playback resumption functionality
Solution Approach 2:
Instead of storing complete multimedia content or complex playback state information, the server creates simplified copies in the form of metadata records. These metadata copies contain only the necessary information to reconstruct playback state, reducing storage burden and management complexity while maintaining playback continuity

AI summary
A multimedia redirection method, a multimedia server, and a computer system. The method includes: receiving a virtual-desktop login request of a user, where the virtual-desktop login request includes an identifier of the user; acquiring, according to the identifier of the user, metadata of a multimedia instance that is not shut down by the user before a last disconnection, where the metadata includes path information of a multimedia file corresponding to the multimedia instance; and sending the metadata to a client of the user so that the client acquires, according to the metadata, multimedia data corresponding to the metadata and plays the multimedia data. The adoption of technical solutions of the present invention can implement that multimedia that is not closed before a last disconnection may be automatically played when a user logs in again, thereby improving experience of multimedia application of the user.
