AI Technical Summary

Technical Problem

Existing cloud gaming technologies suffer from high latency and high maintenance costs for cross-platform adaptation. In particular, data redundancy is severe in multi-touch or high-frequency operation scenarios, leading to increased network transmission burden. Furthermore, differences in screen size and input methods among different terminal devices result in inaccurate coordinate mapping.

Method used

By employing a unified input capture module, an operation abstraction module, a coordinate scaling module, and a binary encoding module on the client side, the original physical input events are converted into a compact binary data stream, which is then decoded and the coordinates restored on the cloud gaming server, enabling unified operation and transmission across platforms.

Benefits of technology

Significantly reduces operation latency, improves response speed and responsiveness, while reducing server-side logic complexity and maintenance costs, and achieves unified processing across platforms.

Abstract

The invention discloses a cross-terminal unified operation transmission system and method in a cloud game scene. The system comprises a client and a cloud game server; the client comprises a unified input capture module, an operation abstraction module, a coordinate scaling module and a binary coding module; the cloud game server comprises a binary decoding module, an event state management module, a coordinate restoration module and an event injection module. The method has the advantages that the operation delay is remarkably reduced, the data volume of a single operation message can be reduced by more than 75% by replacing JSON with a customized binary protocol, the network transmission time is shortened, the end-to-end operation delay is remarkably reduced, and the response speed and the hand feeling of the operation are greatly improved. Through operation abstraction and coordinate scaling of the client, the server does not need to perceive which equipment or input mode the front end is, all inputs are normalized, and logic complexity and code coupling degree of the server are greatly reduced.
