Online Live Broadcast

Online Live Broadcast, an Internet platform built based on real-time distributed streaming media transcoding, provides efficient audio and video live broadcast services with convenient access, low latency, and high concurrency.
Solution Advantages

  • High-Quality, Uninterrupted Experience

    Smooth video playback and traffic reduction by 30% through live video collection from various devices, perception-based enhanced coding, streaming to edge, and cross-platform delivery.

  • Multi-encryption Content Protection

    Security protection mechanisms such as anti-leeching, HTTPS, and API security tokens.

  • High Access Concurrency

    More than 1,000 CDN nodes deployed solely for acceleration to ensure high access concurrency.

  • Product-Level APIs

    Live broadcast APIs and SDKs seamlessly integrated into self-owned platforms; event notification callback for acquiring task execution status in real time.

Business Challenges

  • Interrupted Video Playback

    Unstable network transmission causes poor image quality and high latency, resulting in frame freezing during live video playback.

  • High Resource Consumption

    Live broadcast consumes a large number of bandwidth resources and streaming hardware resources, making it difficult to support cost-effective high concurrency.

  • System Complexity

    Live broadcast procedures usually involve several different platforms and devices, thus increasing operation costs and complexity.

  • Security Risks

    Lack of adequate safety measures leaves risks of hijacking, hotlinking, and inappropriate content in "bullet screen" and online chat rooms unmitigated.

Typical Scenarios

  • Common Scenarios

  • Live Event Broadcast
