To ensure an excellent user experience, we have adopted advanced technology for real-time video transcoding to enable streaming media playback on the Internet. Here is a detailed explanation of our technical principles:

Video Upload

When a user uploads a video to our server, the video is first stored on the server closest to the user. This approach speeds up the upload process and reduces network latency.

Global Backup Synchronization

To ensure data security and reliability, our internal synchronization mechanism replicates the video file across servers around the world. This way, even if a server encounters issues, users can still access the video content from other servers.

Intelligent Segmentation and Real-Time Transcoding

When a user clicks to play a video, our system intelligently segments the video file into multiple parts. Users only need to load and watch the segment they are interested in. We use high-end Nvidia graphics cards for real-time transcoding of these segments to accommodate different network conditions and device requirements. While the user is watching the current segment, the system pre-transcodes the next segment to ensure smooth playback.

User Experience

Our technology ensures that users experience virtually no delay when watching videos. However, it is worth noting that there may be a waiting time of about 5 seconds when a user first plays a video or drags the playback progress bar. This is because the system needs time to transcode the video segments in real time.

The following diagram illustrates the entire process of real-time video transcoding:

Through this efficient video processing and distribution mechanism, we can provide users with high-quality, low-latency video playback experiences.
