    Smart Multi-Bitrate Switch

      Overview

      Adaptive bitrate streaming allows the video player to automatically switch to the audio/video stream with the most appropriate bitrate based on the user's current network conditions. Under poor network conditions, a video stream with a low resolution will be played back to guarantee playback smoothness. Under good network conditions, a video stream with a higher resolution will be switched to automatically to fully utilize the bandwidth and deliver an optimal image quality. To implement this feature, you need to convert the source audio/video stream into audio/video streams with various specifications (including bitrate and video resolution) and package them to generate an adaptive bitrate file, so that the player can automatically select and play back the stream best suiting the current bandwidth. The adaptive bitrate streaming feature of VOD is industry-leading in terms of feature comprehensiveness and ease of use.
      Strength
      Description
      Comprehensive features
      Adaptive bitrate streaming supports HLS and MPEG-DASH formats.
      Adaptive bitrate streaming supports advanced features such as encryption and digital rights management (DRM).
      Ease of use
      All parameters of an adaptive bitrate streaming task of VOD can be set in a template. Rather than configuring complex parameters, you only need to enter a template ID. VOD provides preset templates of common parameter combinations for you to use directly. You can also manage your own custom templates.
      Adaptive bitrate streaming supports automatic task triggering upon upload completion. You can specify the task flow parameters during upload, and the adaptive bitrate streaming task will be triggered automatically upon the completion of audio/video upload, eliminating the need to initiate a task manually.
      Adaptive bitrate streaming can be initiated manually for existing audios/videos. You only need to specify the template ID when initiating a task.
      The VOD Player SDK supports adaptive bitrate streaming and can be integrated quickly and easily.

      Use cases

      Scenario
      Description
      Ecommerce platforms
      Audios/videos are available in multiple definitions. When a viewer plays a product video, playback smoothness is guaranteed first, and the stream with the optimal video definition is switched to automatically based on the viewer’s network conditions.
      Video websites
      The same video is available in multiple definitions. The player automatically switches to the optimal definition based on the current network conditions, guaranteeing a smooth playback.
      UGSV platforms
      The bitrate is automatically selected based on the network conditions of the user's playback device to guarantee smooth playback.
      Online education platforms
      Multiple definitions can be provided for pre-recorded video courses, so that the player can automatically choose the optimal definition for playback based on network conditions. If a course is particularly important and must be watched in a high definition, students can also manually choose the definition (If the bitrate is too high for the video to be played smoothly, pause playback and wait for the video to buffer).
