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.
