Dynamic Video Stream Resolution Switching for Bandwidth Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional interactive multimedia distribution systems face challenges in efficiently managing bandwidth, particularly when subscribers zoom or pan video content, leading to increased demand for higher resolution which strains network resources and increases costs.
Innovation Solution
The system selectively upgrades multimedia content resolution when zoom or pan commands are activated, using a processor to switch between standard and upgraded data streams, conserving bandwidth by restoring standard resolution when these commands are deactivated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the image plane is enlarged on the display device to zoom into a selected image, then the magnification of the selected image is improved, but the displayed resolution is lowered and the definition of the zoomed image deteriorates
Solution Approach 1:
The system dynamically switches between standard and upgraded resolution data streams based on whether zoom or pan commands are active. When a zoom or pan command is detected, the system transitions to delivering an upgraded resolution data stream; when these commands are deactivated, it returns to the standard resolution stream. This dynamic adaptation resolves the contradiction by providing high resolution only when and where needed.
Solution Approach 2:
The system delivers upgraded resolution data streams selectively when zoom or pan operations are performed, concentrating higher quality content on the displayed image plane only during these specific operations. This local quality enhancement ensures that the zoomed or panned regions maintain definition while conserving bandwidth during normal playback.
2Manufacturing precision
If the horizontal and vertical scanning frequencies are raised to implement higher resolution of the zoomed image, then the definition of the selected image plane is improved, but the bandwidth consumption increases and network resources are strained
Solution Approach 1:
The system dynamically adjusts the resolution of the delivered data stream based on the operational state. During zoom or pan operations, it switches to an upgraded resolution stream; during normal playback, it maintains standard resolution. This dynamic resolution adjustment ensures high definition is provided only when necessary, optimizing bandwidth utilization.
Solution Approach 2:
The system changes the resolution parameter of the delivered data stream based on detected commands. When zoom or pan commands are detected, the resolution parameter is upgraded; when these commands are deactivated, the resolution parameter is reduced to standard levels. This parameter change strategy resolves the contradiction between maintaining high resolution and conserving bandwidth.
3Manufacturing precision
If upgraded resolution data streams are delivered continuously to maintain high definition, then the image quality is improved, but the bandwidth is wasted during normal playback when zoom or pan is not active
Solution Approach 1:
The system employs periodic switching between standard and upgraded resolution data streams based on the activation state of zoom or pan commands. Rather than continuously delivering upgraded resolution, it alternates between resolution levels according to user interaction, ensuring high definition is provided only during relevant operations and standard resolution is used during normal playback to conserve bandwidth.
Solution Approach 2:
The system discards the upgraded resolution data stream when zoom or pan commands are deactivated and recovers bandwidth by returning to the standard resolution stream. This selective discarding and recovery of high-bandwidth content ensures that upgraded resolution resources are utilized only when necessary, preventing bandwidth waste during normal playback while maintaining the capability to provide high definition when needed.
Data Source
AI summary
Variable video stream delivery tools include methods and systems that detect activation of a zoom command during presentation of a first stream of data to a multimedia device and that supplants a second stream of data having a higher resolution for a zoomed image plane of the first stream of data in order to conserve bandwidth. Further exemplary embodiments detect activation of a rotational command and that refreshes the second stream of data with a zoomed, spherical-panorama presentation. And, further exemplary embodiments enable restoration of the first stream of data. These tools may be utilized during presentation of media content, when the media content is initially ordered, or when future presentation of media content is selected to record.
