All about Video Streaming Technologies in 2021

As per the survey conducted by Wyzowl, business calls have been reduced by 43% since businesses have started utilizing video conferences. Video-on-demand subscriptions have increased to $383 million in 2021. This shows that video streaming has become an integral part of the business and personal lives of people post Covid-19 pandemic. With the increase in demand and usage, video streaming technology has improved to provide a high-quality and personalized experience for businesses and viewers. In this article, we are going to discuss how video streaming technology works, how it has evolved over the years, and the emerging trends.

Working of Video Streaming Technology Explained

Video streaming services technology enables people to view video content, both live and recorded from the comfort of their homes. It could be video streaming from across borders or the city, the distances have reduced globally. This is how a video is streamed:

Step 1 – Video is captured using a camera

Step 2 – A capture card is used to transfer video to the encoder or any mode of online transfer

Step 3 – The raw video file is converted into a digital format by the encoder

Step 4 – Video in digital format is uploaded onto the video streaming platform

Step 5 – Video file is distributed to the video player at the user’s end through the content delivery network

Development in Video Streaming Technology

  • HTTP Download

In the initial days of video streaming, video files were to be downloaded onto the viewer’s device. This was made possible by Hypertext Transfer Protocol (HTTP). It would take a long time for one video to be downloaded and there were delays in playback. Also, multiple viewers could not watch one video simultaneously. Apple’s Fast Start improved this technology by allowing its users to watch a video before it could be fully downloaded.

  • Customized streaming protocols

The size of video files is larger when compared to Word, PDF, images, or audio files. This made it difficult for viewers to use their mobile phones to download and watch videos. Software and media companies developed custom protocols for video streaming such as Real-Time Streaming Protocol (RTSP), Real-Time Messaging Protocol (RTMP), Microsoft Media Server (MMS).

  • Multicast video streaming technology

This was new video streaming technology as it facilitated sending the same data to multiple recipients at the same time. Using multicast video streaming technology, businesses could deliver live videos on video streaming platforms to thousands of audiences across the world. This meant that businesses could generate increased return on investment using live video streaming.

  • Modern HTTP streaming

Smooth streaming was introduced by Microsoft that leveraged HTTP and existing network infrastructure to provide benefits of custom streaming protocols. Adaptive bitrate delivery (ABR) ensured that viewers were provided a smooth video playback experience with minimal buffering. HTTP Live Streaming (HLS) and HTTP Dynamic Streaming (HDS) video streaming technologies were also introduced.

Technologies that Increase the Efficiency of Video Streaming

  • Utilization of ST2110 in UHD workflows

ST2110 is the standard to transfer media files as this protocol is more flexible than SDI interconnections. As the consumption of video content is increasing, businesses are using the latest technology to offer high-quality and fast video streaming services.

  • Dynamic ad insertion

DAI has been operational in proprietary solutions and it is hard to utilize at a large scale. Dynamic ad insertion helps OTT platforms to drive revenue. DAI and OTT merged to provide hyper-targeted advertising. It boosts revenues, beats ad-blockers, and personalizes the end-user experience.

  • Context adaptive Delivery (CAD)

CAD creates a workflow dynamic that enables balancing the context of video content and the context of the delivery network. Since artificial intelligence (AI) is implemented, data can be collected across the network and be leveraged. CAD process ensures that traffic surges can be supported with the data-driven dynamic adaptive delivery workflow.

Emerging video streaming technology

  • WebRTC

Google launched WebRTC to support peer-to-peer streaming and real-time latency. Several video conferencing applications and platforms use WebRTC to enjoy the benefits of its ultra-low latency potential.

  • SRT

Any video streaming platform that wants to provide reliable security and low latency can utilize the SRT streaming protocol. SRT can stream videos faster than HLS and RTMP combined. Another notable benefit of SRT is its responsiveness to carry the capacity of video to be streamed based on the internet speed of the viewer which avoids lagging, buffering, and failure.

  • Immersive video streaming

360 video streaming and virtual reality that makes the user feel they are a part of the video they are watching is a hot technology. This can be used both in business and for entertainment purposes. 360 video streaming is easy to create using cinematic elements to improve the experience of the users.


All the businesses who want to survive the work from home culture introduced due to the Covid-19 pandemic should invest in virtual communication platforms for their internal and external communication. Customer support, customer engagement, engagement with leads, building a brand, interacting with a live audience, and establishing a strong online presence can all be done using video streaming platforms. Businesses can host, manage, deliver high-quality video content on a white-label platform to provide top-notch security, monetize video and deliver video content globally.
