      Origin Server Introduction

      Tencent Cloud Video on Demand (VOD) offers integrated high-quality media services, such as production and upload, storage, transcoding, Media Processing Service (MPS), media AI, copyright protection, and play for media, such as audio, video, and images.

      VOD Origin Server Advantages

      Advantage
      Description
      Multi-dimensional cost optimization
      VOD provides media services with strategies such as cold storage and smart bitrate reduction. By optimizing costs in detail according to real-time media playback, it effectively saves storage and distribution costs for users.
      Scenario-based transcoding
      VOD offers superior transcoding capabilities for various industry scenarios. Utilizing technologies like intelligent scene recognition, dynamic encoding, and the CTU/row/frame three-level bitrate precision control model, it achieves higher subjective image quality at a lower bitrate (nearly 50%), realizing high image quality at a low bitrate, and saves network traffic and storage costs.
      Stable storage
      VOD supports backup storage of video files across architectures and devices, and provides cross-region disaster recovery and user resource isolation, greatly enhancing storage stability.
      High-quality upload
      VOD improves data transfer efficiency and stability in poor network conditions through various upload acceleration measures, such as scheduling optimization, global multi-storage park coverage optimization, link supplementation, transmission optimization, and the Quick UDP Internet Connections (QUIC) protocol, improving the upload speed and success rate.
      Copyright protection
      Copyright protection features of VOD include the hotlink protection, ghost watermark, HTTP Live Streaming (HLS) private encryption, and commercial-grade Digital Rights Management (DRM) encryption, providing high-level security for content rights owners.
      Audio/video distribution optimization
      When users select the VOD origin server, the EdgeOne acceleration service automatically enables the pre-fetching capability of audio and video files by default. It supports segment fetching and caching of HLS/DASH/MP4/FLV format files to edge nodes when a client request is made, enhancing the response speed of video files, thereby optimizing the time it takes to start playing videos and reducing the rate of playback stuttering.

      VOD Origin Server Use Cases

      Application Scenario
      Scenario Description
      Online education
      Online education refers to a teaching method that uses the network as a medium, where students and teachers conduct educational activities online. Platforms generally have a large number of audio and video teaching resources, most of which are recorded and uploaded by registered teachers. VOD offers features like multi-end playback, smart subtitles, copyright protection, time shifting, VOD to live streaming, and content review for this scenario, helping users quickly build an audio and video teaching platform.
      Ecommerce apps
      Ecommerce apps are online transaction platforms where enterprises and individuals can market and sell their products. Sellers typically produce and upload product images and videos to better showcase their products. Buyers can also upload images and videos to share feedback about their shopping experience or write product reviews. VOD provides features such as HD with low bitrate, smart screenshot cover, multi-bitrate smart switching, upload acceleration, and tag classification for this scenario, thereby helping users better showcase their ecommerce products.
      TV stations and over-the-top (OTT)
      TV stations and OTT primarily offers streaming media services based on TV terminals. VOD provides features for this scenario, such as Top Speed Codec (TSC) transcoding, multi-bitrate smart switching, copyright protection, media AI recognition, VOD to live streaming, and video production, helping users quickly build a smart media asset library and offering diverse applications like cloud editing and video directing.
      Live streaming apps
      Live streaming apps allow hosts to broadcast, deliver commentary, or perform live over the network, such as live show streaming, game live streaming, live classes, live shopping, and live Q&A. VOD provides capabilities such as live recording, time shifting, live editing, TSC, and VOD to live streaming, to help users quickly establish a stable and reliable live streaming platform.

      Use Limits

      Using the VOD origin server will automatically provide more suitable distribution acceleration configurations for your media content. Therefore, when using the rule engine and site acceleration configurations for a VOD origin server, the VOD default configurations will be used for some operations to offer better distribution acceleration effects. To prevent conflicts between custom configurations and default settings, some site acceleration configuration and rule engine operations will not be supported. The detailed limits are as follows:
