Understanding TRTC and Its Implementation

Tencent RTC - Dev Team


TRTC(Tencent RTC) is a powerful cloud service designed to facilitate real-time audio and video communication. In this article, we will delve into the world of TRTC, exploring its capabilities and applications, and how it can revolutionize the way we communicate.

What is TRTC?

Let's start by analyzing the meaning of the name TRTC. Tencent Real-Time Communication is the official definition of TRTC.

Firstly, let's decipher what TRTC stands for:

T — Tencent

R-T — Real-Time

C — Communication

TRTC(Tencent RTC) is a cloud-based service that enables real-time audio and video communication across various platforms. Developed by Tencent, a leading technology company known for its popular instant messaging apps QQ and WeChat, TRTC leverages the company's expertise in communication technology to provide a seamless and high-quality experience for users.

Capabilities of TRTC

TRTC(Tencent RTC) offers cross-platform solutions for audio/video calls and low-latency interactive live streaming. With SDKs for mini programs, web, Android, iOS, Electron, Windows, macOS, and other platforms, you can quickly integrate TRTC services into your projects and connect to the TRTC backend. You can also combine TRTC with other Tencent Cloud products such as Instant Messaging(IM) , Cloud Streaming Services (CSS), and Video on Demand (VOD) to explore more use cases. The figure below shows how TRTC works together with other products.


High-quality audio and video communication: TRTC offers high-quality audio and video communication, ensuring clear and smooth conversations. It employs advanced audio and video processing algorithms, such as noise reduction and echo cancellation, to deliver an exceptional user experience.

Cross-platform compatibility: TRTC supports a wide range of platforms, including Android, iOS, Windows, macOS, and web browsers. This cross-platform compatibility allows users to communicate seamlessly, regardless of the device they are using.

Low latency: One of the key features of TRTC is its low latency, which ensures real-time communication with minimal delays. This is particularly important for applications such as online gaming, remote collaboration, and live streaming, where real-time interaction is crucial.

Scalability: TRTC is designed to handle a large number of concurrent users, making it suitable for applications that require massive scalability, such as online conferences, virtual events, and social networking platforms.

Security and privacy: Tencent's Real-Time Communication service prioritizes user security and privacy. It employs end-to-end encryption to protect user data and ensure secure communication.

Technical Implementation of TRTC

The original design intention of WebRTC was to solve 1v1 audio and video call problems. However, in actual enterprise-level applications, we often need more complex functions, such as multi-person calls, real-time meeting control, cloud mixing, and real-time recording. This requires us to innovate and expand on the basis of WebRTC.

TRTC(Tencent RTC) has successfully addressed this issue by introducing mirrored instances in the cloud. These mirrored instances act like "pseudo-users" running in the cloud. They can communicate data with real users in the browser, while simultaneously "translating" the received data in real-time, converting it into a data format that the TRTC system can understand, thereby integrating it into the existing TRTC system.

This is akin to adding a translator who understands both Arabic and Chinese between two Arabic-speaking individuals, enabling those who originally could not understand each other to comprehend what the other party is saying. Through this method, Tencent has successfully extended its RTC capabilities to browsers that support WebRTC, thereby meeting the needs of enterprise-level applications.

This innovative solution fully demonstrates Tencent's leading position and strong capabilities in real-time communication technology,and it also provides a good reference for other enterprises.
