Control Device Pulling Streaming Data for Cloud Gaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cloud gaming technologies are limited by the requirement for a cloud gaming client to be installed on playback devices, restricting the range of devices that can load virtual scenes due to differences in data transfer protocols and hardware configurations.
Innovation Solution
A virtual scene loading method that involves a control device pulling a streaming media playback address from a cloud device, transmitting a media projection request to a playback device, and modifying file parameters to replace local file addresses with the streaming media playback address, allowing playback devices without a cloud gaming client to load and play virtual scenes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cloud gaming client is installed on playback devices to enable virtual scene loading, then the cloud gaming functionality is achieved, but the device compatibility is limited due to differences in data transfer protocols and hardware configurations
Solution Approach 1:
The patent introduces a control device as an intermediary between the cloud device and playback device. The control device generates a media projection request with modified file parameters that replace the original file address with a streaming media playback address, enabling playback devices without a cloud gaming client to access cloud gaming services through standard media projection protocols
Solution Approach 2:
The patent enables playback devices to access cloud gaming services through their existing media projection functionality, rather than requiring a dedicated cloud gaming client. By modifying file parameters to use streaming media playback addresses, the system allows standard media players to universally access cloud gaming content across different device types and protocols
2Reliability
If a cloud gaming client is required on playback devices, then protocol compatibility is ensured, but the complexity of device installation and configuration increases
Solution Approach 1:
The patent extracts the cloud gaming client requirement from the playback device by moving the protocol conversion functionality to the control device. The control device modifies file parameters to use streaming media playback addresses, eliminating the need for playback devices to install and configure cloud gaming clients while maintaining protocol compatibility through the control device's mediation
3Ease of operation
If local media files are used for projection, then playback functionality is simple, but cloud gaming streaming capability is not achieved
Solution Approach 1:
The patent changes the file parameters of the media projection request by replacing the original file address with a streaming media playback address. This parameter modification allows the playback device to maintain simple media projection operations while actually retrieving and playing cloud gaming streaming content from the cloud device through the control device
Data Source
AI summary
A streaming method executed by a control device includes receiving a streaming media playback address of a cloud streaming service returned by a cloud device, and transmitting a media projection request corresponding to a local media file stored on the control device to a playback device. The method further includes transmitting a loading instruction indicating to start loading the virtual scene to the cloud device, generating initial file parameters corresponding to the local media file and replacing a file address of the local media file in the initial file parameters with the streaming media playback address to obtain modified file parameters. The method further includes returning the modified file parameters to the playback device, the modified file parameters providing the streaming media playback address instead of the initial file parameters corresponding to the local media file.
