    Live Event Broadcasting (LEB) is the ultra-low-latency version of CSS. It delivers superior playback experience with millisecond latency and is suitable for scenarios with high requirements on latency, such as online education, sports streaming, and online quizzes.

    Product Architecture



    Playback with millisecond latency

    LEB uses the UDP protocol to keep the latency within 1s, much lower than 3-5s in traditional live streaming. This, along with excellent instant streaming performance and low stutter rate, guarantees a superior streaming experience.

    Various features and smooth migration

    LEB integrates a wide range of LVB features including live push, transcoding, recording, screencapture, porn detection, and playback. It also allows smooth migration from LVB.

    User-friendly, secure, and reliable

    You can easily integrate LEB as it uses standard protocols. You can use it for playback on Chrome and Safari without installing any plugins. Moreover, its protocols encrypt streams by default for improved security and reliability.


    LEB billable items include basic services and value-added services. Basic services are billed by upstream and downstream traffic/bandwidth, and value-added services such as live transcoding, recording, screencapture, and porn detection are billed by resource usage. For details, see Pricing Overview.
