What Is Live?

Huawei Cloud Live is the cumulation of years of video expertise. It offers a secure and high-concurrency E2E livestreaming solution while delivering a low-latency HD experience. Huawei Cloud Live provides Cloud Stream Live and Low Latency Live (LLL). Cloud Stream Live improves the stability and efficiency of high-concurrency livestreaming and provides powerful real-time media processing capabilities. LLL reduces the E2E latency to milliseconds and is more adaptable to poor network conditions. It is suitable for scenarios that require low latency and good content synchronization.

Live offers the following subproducts:

Cloud Live: This easy-to-use livestreaming service provides diverse live acceleration capabilities for entertainment, e-commerce, and education scenarios.
Cloud Live involves the following two scenarios. Table 1 describes the differences between the two scenarios.
- Cloud Stream Live improves the stability and efficiency of high-concurrency livestreaming and provides powerful real-time media processing capabilities.
- Low Latency Live (LLL), which is built on cutting-edge technologies such as transmission protocol optimization, dynamic routing, and low-latency transcoding, slashes live latency to milliseconds in latency-sensitive scenarios and delivers an unrivaled experience even when there are a massive number of concurrent requests.
MediaLive: This broadcast-grade livestreaming service supports features such as channel management and content encryption, making it an ideal option for media assets and broadcasting.

**Table 1** Comparison of Cloud Live sub-scenarios
Cloud Live Sub-Scenario	Cloud Stream Live	LLL
Streaming Protocol	RTMP, HTTP-FLV, and HLS	WebRTC
E2E Latency	RTMP and HTTP-FLV latency > 3s HLS latency > 6s	E2E latency < 800 ms
Adaptable Network	Average	Good
Application Scenario	Livestreaming that is insensitive to latency	Interactive livestreaming that requires low latency and good image synchronization
General Capability	Functions such as real-time transcoding, recording, real-time snapshot capturing, content encryption, authentication, and statistics analysis More than 2800 acceleration nodes in China and more than 800 outside China to provide superlative service experience
