In the digital age, the way we consume content has dramatically evolved. Streaming has become a critical part of our daily lives, allowing us to access various media instantly.
From video and music to live events, streaming has transformed how we experience entertainment and information. In this blog, we’ll explore what is streaming and how does it work? Which are popular platforms, technical requirements, and their future impact.
What is Streaming?
Streaming transmits data, typically audio and video, over the web in real-time. Unlike downloading, where files are saved to your device before playback, streaming enables continuous playback while data packets are received and played simultaneously. This technology has revolutionized media consumption by allowing users to enjoy content without needing sizable local storage.
Brief History of Streaming
The concept of streaming dates back to the early 1990s, but it gained significant popularity in the 2000s as internet speeds improved.
One of the first successful streaming services was Internet Radio, which began delivering audio content to users over the web. The video streaming platforms’ rise in the mid-2000s further accelerated the streaming revolution.
Types of Streaming
Streaming comes in various forms, catering to different interests and preferences:
Video Streaming
Delivering video content over the Internet, popularized by platforms like Netflix and Hulu.
Music Streaming
Users can access an extensive library of songs on platform similar to Spotify and Apple Music.
Live Streaming
Broadcasting real-time events, gaming, and live performances on Twitch and YouTube Live platforms.
How Does Streaming Work?
Content Creation and Encoding
Content creators produce media in various formats, such as MP4, AVI, or MKV for videos and MP3 or FLAC for audio. Before streaming, the media undergoes encoding and compression. Later it gets converted into a digital format suitable for transmission over the Internet.
Content Storage
The encoded media is stored on Content Delivery Networks (CDNs) servers. These CDNs have numerous data centers worldwide, ensuring that content is geographically distributed for faster and more reliable access.
Content Distribution
When a user initiates playback, the media player sends a request to the CDN server nearest to the user. The CDN then continuously delivers the media as small data packets to the user’s device.
Buffering and Playback
Data packets are temporarily stored in a buffer on the user’s device during streaming. This buffer ensures a smooth playback experience by pre-loading enough content to handle fluctuations in internet speed. The media player continuously updates the buffer as it plays, minimizing interruptions due to network variability.
Popular Streaming Platforms
You might be aware of what is streaming and how does it work? Now let’s explore the list of popular streaming platforms. Check the details below:
Video Streaming Platforms
As the video streaming pioneer, Netflix dominates the market with millions of subscribers worldwide. Other popular platforms include Amazon Prime Video, Disney+, and HBO Max.

Live Streaming Platforms
Twitch is the go-to platform for live gaming streams, while YouTube Live is favored for a broader range of live content, including events, tutorials, and Q&A sessions.
Founded in 1997, Netflix, a video streaming platform, started as a DVD rental service. Its transition to a streaming platform began in 2007. At the same time, Statista’s report shows that during the survey of the first quarter of 2023, Spotify had 210 million premium subscribers worldwide and 209 million active free users.

How Does Streaming Differ from Downloading?
Streaming and downloading differ in their fundamental approaches to accessing media content. The entire file is stored on your device when downloading a movie or song. Once the download is complete, you can watch or listen to the content whenever you desire. In contrast, streaming lets you enjoy media without downloading the entire file.
Downloading has advantages, such as providing a buffer-free experience and keeping your favorite content offline. However, constantly downloading large media files, exceptionally high-definition movies, can quickly consume your available hard drive space.
On the other hand, streaming eliminates the need for local storage, meaning you can access content without worrying about space limitations. Despite the occasional challenge of streaming with a slow internet connection, the convenience and variety of streaming options have made it incredibly accessible.
Streaming has never been more user-friendly with various platforms like music services, including Spotify and Apple Music, video players like YouTube, Netflix, Hulu, and HBO Max, social streaming platforms such as Twitch, and many games and apps.
Does streaming use the User Datagram Protocol (UDP) or the Transmission Control Protocol (TCP)?
Streaming methods employ UDP or TCP transport protocols for moving data packets across networks. UDP and TCP are used with the Internet Protocol (IP). TCP establishes a dedicated connection before transmitting data and ensures that data packets arrive in the correct order.
On the other hand, UDP lacks these features, resulting in faster data transmission than TCP, though some packets may be lost during the process. To draw an analogy, TCP can be likened to a package delivery service that requires a recipient’s signature, ensuring fewer lost packages.
In contrast, UDP functions like a delivery service that leaves every package on the front porch without requiring a signature. As a result, UDP delivers data faster, even if no one can receive and sign for the packages.
In streaming scenarios, the choice between UDP and TCP depends on the specific priorities. When speed precedes absolute reliability, such as in real-time video conferences where seamless interaction is vital, a few lost data packets are generally tolerable. In such cases, UDP is the preferred option.
Conversely, when reliability is paramount, protocols like HTTP live streaming (HLS) and MPEG-DASH use TCP as transport. Many video-on-demand services also use TCP to ensure the secure and reliable delivery of content.
Technical Requirements for Streaming
Internet Connection
A good internet connection is needed for smooth streaming. Standard-definition videos typically require at least 3 Mbps, while high-definition videos may need 5-8 Mbps or more.
Device Compatibility
Streaming is compatible with various devices, including smartphones, tablets, computers, smart TVs, and streaming devices like Roku and Amazon Fire Stick.
Codecs and Bitrates
To optimize streaming, content is encoded with specific codecs that efficiently compress the data without compromising quality. Standard codecs include H.264 and H.265 (HEVC). Bitrate refers to the amount of data transmitted per second; higher bit rates result in better quality but require faster internet speeds.
Pros and Cons of Streaming
Advantages of Streaming
Instant Access
Users can start consuming content immediately without waiting for downloads.
Large Library
Streaming services offer vast libraries of movies, shows, and music, giving users endless choices.

What Factors Affect Streaming Performance?
Network-related Factors
Network Latency
Latency terms as the delay or lag in data transmission. Various factors, such as the geographical location of content servers, can impact latency and subsequently affect streaming speed.
Network Congestion
High data traffic on the network can lead to congestion, causing streaming performance to degrade as data packets experience delays or get lost.
User-related Factors
WiFi Problems
WiFi connectivity issues can disrupt streaming. Restarting the local area network (LAN) router or switching to a wired Ethernet connection can significantly improve streaming performance.
Underperforming Client Devices
Streaming videos demand sufficient processing power from the device. If the streaming device is burdened with numerous background processes or is slow, it can adversely affect the streaming experience.
Insufficient Bandwidth
Smooth video streaming requires adequate bandwidth. A minimum of around 4 Mbps for standard streaming is recommended, while high-definition video may demand even more bandwidth to ensure a seamless viewing experience.
