How Cloud Gaming Works
Cloud gaming is a complex system that relies on advanced technologies and infrastructure to deliver an immersive gaming experience to users. Let’s dive into the detailed workings of cloud gaming:
1) User Initiation:
The cloud gaming process begins when a user selects a game to play from the cloud gaming platform’s library. This can be done through a dedicated application on a device or through a web browser.
2) Input Transmission:
Once the user has chosen a game, their inputs, such as button presses, mouse movements, or touchscreen interactions, are transmitted from the user’s device to the cloud gaming server. These inputs are sent over the internet using a low-latency communication protocol to minimize the delay between the user’s actions and their impact in the game.
3) Cloud Server Processing:
On the cloud server side, powerful hardware resources and specialized software handle the processing and rendering of the game. The server receives the user’s inputs and processes them to determine the corresponding actions in the game. This includes physics calculations, rendering of 3D graphics, audio processing, and game logic.
4) Frame Rendering:
Once the server has processed the user’s inputs, it generates the frames that make up the visual content of the game. These frames are rendered based on the game’s current state and the user’s inputs. The rendering process involves creating a 3D environment, applying textures, lighting effects, animations, and other visual elements to produce the final frames.
5) Video Encoding and Compression:
Compression techniques remove redundant or less noticeable visual information while retaining the essential details to minimize bandwidth requirements.
