Real-Time Communication (TRTC) enables live broadcast scenarios by providing low-latency, high-quality audio and video transmission. It works by utilizing WebRTC technology, which allows for peer-to-peer communication between browsers and mobile applications without the need for plugins.

Key features of TRTC for live broadcasts include:

  1. Low Latency: TRTC offers minimal delay, which is crucial for real-time interactions, allowing audiences to watch live streams with minimal lag.

    • Example: In a live concert broadcast, TRTC ensures that the audience experiences the performance as if they were present, with minimal delay between the performance and the broadcast.

  2. High-Quality Audio and Video: TRTC supports high-resolution video (up to 1080p) and high-quality audio, enhancing the viewing experience.

    • Example: During a sports event, TRTC delivers crisp, clear video and audio, allowing viewers to see every detail and hear every sound clearly.

  3. Scalability: TRTC can handle a large number of concurrent users, making it suitable for large-scale live broadcasts.

    • Example: During a major sports final, TRTC can support millions of viewers simultaneously without compromising quality.

  4. Interactive Features: TRTC supports features like live chat, polls, and Q&A, enhancing audience engagement.

    • Example: In an online education session, students can ask questions in real-time, and the teacher can respond immediately, creating a dynamic learning environment.

  5. Reliability: TRTC ensures stable connections even in poor network conditions, using techniques like adaptive bitrate streaming.

    • Example: In a remote area with limited internet connectivity, TRTC adjusts the video quality to maintain a smooth broadcast.
