To establish a high-speed channel between the region where the streamer or viewers reside and mainland China, ApsaraVideo Live provides the premium streaming acceleration feature. This feature helps accelerate the transmission of live streams. This topic describes the premium streaming acceleration feature, its benefits, and how to configure it.

Introduction

Premium streaming acceleration ensures the most efficient and optimal transmission of video streams between the region where the streams are collected and the region where the streams are played. This feature is implemented by establishing a high-quality network transmission channel between the two regions. By using premium streaming acceleration, you can reduce stuttering and latency during live streaming for global users.

Note
  • You can configure premium streaming acceleration only for domains in the China (Shanghai), China (Beijing), China (Qingdao), China (Shenzhen), and Singapore regions.
  • If you use live center pushing, you cannot use premium streaming acceleration. To resolve this issue, you can submit a ticket to change your pushing mode to edge pushing.
  • You are charged for using premium streaming acceleration. For more information, see Fees of premium streaming acceleration.

Benefits

  • Low access costs: To use premium streaming acceleration, you only need to configure it in the ApsaraVideo Live console with a few simple steps. No development workloads or servers are required, which saves costs.
  • High communication quality and availability: Premium streaming acceleration is supported by the state-of-the-art infrastructure of Alibaba Cloud, which ensures high communication quality and availability.
  • High speed and stability: Live streams are pushed or pulled to nearby edge nodes for delivery. Nodes around the world are connected by using high-speed channels.
  • Worldwide support: Premium streaming acceleration is provided in important business areas worldwide, such as Asia, Europe, and North America.
  • Flexible billing: The billing cycle of premium streaming acceleration is one day. You can configure the transmission network for specific streams to meet different business needs.

Scenarios

  • The streamer resides in Hong Kong, Macau, Taiwan, or a region outside China. Premium streaming acceleration is used to push live streams to mainland China and deliver the live streams in mainland China.
  • The streamer resides in mainland China. Premium streaming acceleration is used to pull live streams to the specified acceleration area for delivery.

Configuration

You can use the ApsaraVideo Live console to configure premium streaming acceleration for streaming domains. For more information, see Configure global acceleration.

Notice
  • You can configure premium streaming acceleration only for streaming domains.
  • To configure premium streaming acceleration for a streaming domain, make sure that the streaming domain is associated with a pushing domain that uses edge pushing. For more information about the process of domain association, see Bind the domain names. For more information about the operations of domain association, see Bind an ingest domain to a streaming domain.

Configuration examples

The following table describes several scenarios to show you how to select a live center and configure premium streaming acceleration.

Where your casters are located Where your audience is located Requirements for the region as the live center and the edge group for streaming domains Configuration of premium streaming acceleration Description
Mainland China Mainland China
  • Select the China (Shanghai), China (Beijing), China (Shenzhen), or China (Qingdao) region as the live center if you do not need to use a production studio.
  • Select the China (Shanghai) region as the live center if you need to use a production studio.
  • If you use OSS to store recording files and snapshots, make sure that your OSS bucket is in the same region as the live center.
N/A You can configure premium streaming acceleration for a single stream or for all the streams under an application of an added domain name.
Mainland China Hong Kong, Macao, Taiwan, and countries and regions outside China
  • Select the China (Shanghai), China (Beijing), China (Shenzhen), or China (Qingdao) region as the live center for ingest domains and streaming domains.
  • Set the Edge Group parameter to Outside Mainland China for streaming domains.
Configure premium streaming acceleration for Alibaba Cloud regions in the United States, Germany, Singapore, Hong Kong, or Indonesia based on the region where your audience is located.

Acceleration type: streaming acceleration

In this scenario, the casters are located in mainland China, whereas the audience is located in Hong Kong, Macao, Taiwan, and countries and regions outside China. If the audience is located in multiple Alibaba Cloud regions, you must configure premium streaming acceleration for these regions to ensure successful acceleration.
