What is a Streaming Server? When streaming video and audio online, the server is required to be more than just a large storage hard drive, it must become a software that plays data to your computer, called Streaming Server. A Streaming Server is capable of handling many different file formats, while other platforms only support a few specific formats. So what is a streaming server? We invite you to find out through VinaHost‘s article below.

1. What is a Streaming Server?

Streaming refers to the continuous transmission of data on the internet from a streaming source to devices such as desktop computers, laptops, smartphones, etc. The streaming server, or Streaming Server, is the software platform that supports this.

Simply, Streaming Server is a type of server designed to transmit online multimedia data such as video, audio, images from the source to the user without having to download it first, helping to save bandwidth and save money.

2. How Does a Streaming Server Work?

Streaming server can connect to a web server to transmit data. When accessing a website hosted on a web server, you can select a file to view. When you select the file, the server will identify and transmit the data directly to you from the Streaming server without going through the web server anymore. This process follows a protocol to regulate data transfer between devices, ensuring that the data gets where it needs to go.

what is streaming server — Streaming Server is a type of server designed to transmit online multimedia data such as video, audio, images from the source to the user without having to download it first, helping to save bandwidth and save money.

TCP is one of the most important protocols in data transmission on the network. It breaks data into packets for transmission. The FTP protocol has the ability to recover damaged and lost packets and regenerate packets in case of need. This makes web browsing and file downloading simpler, especially when there are lost packets or slow network connections, still ensuring you receive your data. However, these protocols are not suitable for streaming data transmission.

To overcome this problem, Streaming Video and Audio uses real-time data transmission protocols. The files are divided into small parts and sent sequentially to the destination. These protocols include:

Real-time transfer protocol (RTP)
Real-time streaming protocol (RTSP)
Real-time transport control protocol (RTCP)

These protocols act as an additional layer to web traffic management protocols. Other web protocols still work in the background, while the Real-time protocol is transmitting the necessary data. To help with load balancing, these protocols interact with each other. In case there are too many simultaneous accesses to a file, the server will stop starting some streaming channels.

9. FAQs

9.1. What is the difference between buffering and latency?

	Buffering	Latency
Define	Buffering is when a video player preloads a portion of the video data into memory to ensure smooth playback, especially if the viewer’s Internet connection is unstable.	Latency is the amount of time between when a video is recorded and when it is displayed to the viewer. For live streaming, latency is the time difference between the actual event and the moment it appears on the viewer’s screen.
Reason	Slow Internet connection: Internet speed is not fast enough to play real-time videos. Network congestion: High network traffic slows down data transmission. Server problems: The streaming server is having technical problems or is overloaded. High bit rate: Video with high resolution and bit rate requires more data to be transmitted, easily causing lag on slow connections.	Encoding and decoding: Video encoding time on the server and decoding on the viewer’s device. Transmission delay: The time it takes for data to travel from the server to the viewer over the Internet. Content Delivery Network (CDN): CDN’s effectiveness in delivering content to different geographical locations. Processing latency: Processing time for tasks such as DRM, analytics, and ad insertion.
Impact on user experience	Interruption: Video pauses to load more data. Loading icon: A spinning wheel or loading bar when the video player is buffering content.	Live interactions: High latency affects real-time interactions such as live chat, Q&A, and polls. Synchronization: High latency distorts the time between real action and the image the viewer sees, making real-time monitoring difficult.

Understanding this difference will help you solve specific problems in video streaming, ensuring a better experience for your viewers.

9.2. What are the bandwidth requirements for streaming?

Bandwidth requirements for streaming depend on the quality of the video or audio. Below are the basic requirements for different qualities:

Play Video

Standard Definition (SD) 480p: 1.5 to 3 Mbps.
High definition (HD) 720p: 3 to 5 Mbps.
Full HD 1080p: 5 to 8 Mbps.
Ultra HD 4K: 15 to 25 Mbps.

Broadcasting

Standard quality (96 kbps): 0.1 Mbps.
High quality (160 kbps): 0.2 Mbps.
Very high quality (320 kbps): 0.3 Mbps.

For the best experience, make sure your bandwidth is slightly higher than the minimum requirement to compensate for changes in Internet speed and other devices using the network.
