Technical Details

Data Retrieval from reMarkable Memory

The reMarkable Screen Streaming Tool leverages a combination of techniques to capture the screen data from the reMarkable tablet's memory. It utilizes low-level access provided by the device's operating system to retrieve the necessary data. This approach ensures that the tool does not require any unauthorized modifications to the reMarkable tablet.

Data Transmission via WebSocket

Once the screen data is obtained from the reMarkable tablet's memory, the tool serves it to clients via a WebSocket connection. A WebSocket is a communication protocol that provides full-duplex communication channels over a single TCP connection, making it ideal for real-time data streaming. The WebSocket connection ensures that the screen data is transmitted efficiently and promptly to connected clients.

Client-Side Rendering with HTML Canvas

On the client side, the reMarkable Screen Streaming Tool fetches the transmitted screen data and renders it using an HTML canvas element. The HTML canvas provides a powerful and flexible platform for displaying graphics and images on web pages. By leveraging the capabilities of the HTML canvas, the tool ensures a performant and lossless streaming experience for users.
