Introduction to POLYV Online Video Live Streaming

When it comes to live video streaming, many people think of various professional cameras, high-end matrix switchers, complex video encoding technologies, and powerful technical teams... However, what exactly is online video live streaming? Online video live streaming uses streaming media technology to broadcast live over the internet, while also supporting recording functions (the system automatically records for users to watch on demand). Users access a designated live streaming website page (URL), and their access request is directed to a publishing server node, where they obtain streaming media data and watch the live video content directly through a web browser. What is the overall architecture of online video live streaming? Online video live streaming consists of video and audio capture tools, encoding tools, servers, networks, players, and other components.

Function: Used to input signals from cameras or video switchers into encoding equipment, forming preliminary multimedia data. Implementation: Video and audio capture tools can be divided into three levels: entry-level, standard-level, and professional-level. The corresponding capture devices differ accordingly. For example, entry-level only requires a simple device like a smartphone, webcam, or DV; standard-level requires a high-definition camera, video capture card, etc.; professional-level requires three or more high-definition cameras, matrix switchers, and other professional equipment.

Encoding Tools

Function: Used to create, capture, and edit multimedia data, forming streaming media formats. This can be accomplished by a computer with audio/video hardware interfaces and production software running on it. Implementation: Users can use a computer with Flash Media Encoder installed, which also has hardware interfaces for connecting video and audio capture devices, such as IEEE 1394 interfaces, USB 3.0 interfaces, etc.

Server

Function: Stores and controls streaming media data. Implementation: Can be provided by domestic cloud video live streaming service providers.

Network

Function: A network suitable for multimedia transmission protocols or real-time transport protocols, capable of delivering high-definition, smooth live video streaming. Implementation: We need to consider three aspects: video data upload, video data transmission, and video data download. Generally, entry-level upstream bandwidth requires at least 1Mbps (China Telecom/China Unicom), standard-level requires at least 2Mbps (China Telecom/China Unicom), and professional-level requires at least 4Mbps (China Telecom/China Unicom). The video data transmission network can be provided by domestic cloud video live streaming service providers.

Player

Function: Allows clients to browse streaming media files and customize player types. Implementation: Can be provided by domestic cloud video live streaming service providers. To ensure high-definition and smooth online video live streaming, a stable video platform is essential. The cloud video live streaming platform, as an emerging technology platform in China, has become the best choice for online video live streaming due to its high-definition, smooth video quality and convenient operation. To guarantee high-definition and smooth live video playback, POLYV has built its own CDN network nodes domestically (including overseas nodes) and also utilizes the CDN networks of top domestic CDN providers (ChinaNetCenter, ChinaCache, and Dilian). This results in over 400 domestic network nodes and more than 3,000 servers in China, ensuring a maximum concurrent online capacity of millions.
