Video streaming and delivery is a resource intensive process. This is attributed to the various networks a video stream must pass through as well as the quality of the video, as higher bitrates and resolutions require more information related to that stream to be sent to the end viewer. As a result of this requirement, it’s not recommended to broadcast video using your own server. For companies, this can result in bottlenecks from the servers hosting or unnecessary costs to scale a server infrastructure.
Streaming video process
Streaming video content is resource intensive for both the sender and receiver. In order to deliver a smooth video stream, a constant flow of data is required between both participants. To help facilitate this, an approach was devised to divide packets into various chunks. Often called video chunks, these can be encrypted and decrypted independently. These chunks can also be assembled back-to-back to form the “original” packet. This gives video streaming a bit more flexibility, especially as so many packets are required to form a video.
To aid further in this process, video chunks are generally preloaded before playback begins. This process is called buffering and is found on video streaming, including live streams which will have a few seconds of delay to accommodate this.
Despite the word buffering having a negative association, the technology aids in minimizing playback disruptions. Rather than the video halting each time a video chunk is lost, the player can instead playback from the preloaded video chunks while it attempts to recover the missing one.
As mentioned, though, there is a clear negative association with the process of buffering. Once the spinning wheel appears, denoting that the player is preloading more video chunks due to reaching a point in playback where the appropriate video chunk was not received in time, it’s very likely for viewers to become frustrated and abandon the content they had originally planned to watch. Consequently, any methods that allow for reducing latency to speed up delivery and avoid the video player reaching that missing video chunk before the preloaded chunks are used is a major benefit.
Why choose CDN?
CDNs offer an easy way to increase the speed of a website while also lowering the latency. Therefore, they are essential for the fast, efficient and secure delivery of content to users around the world. This content is not simply limited to website content alone; it can also comprise 4K and HD-quality video, audio streams, apps, games and OS updates. With website visitor attention spans growing shorter by the day, it is imperative to deliver this content as quickly as possible.
As more businesses go online, and the world comes together on the Internet to shop, connect, and share, content providers face an increasing array of challenges such as: delivery of different types of content, adjusting content for different device types (device detection), and securing data and the online presence of their end users. The inherent capabilities of a content delivery network mean that CDN providers are uniquely positioned to help businesses overcome these diverse challenges of media delivery.
For almost 20 years, CDNs have formed the unseen backbone of the Internet delivering online content for retail, finance, healthcare, and other businesses to end users around the world with speed and at scale. If you’ve done almost anything online, you’ve benefited from a CDN – whether you knew it or not.
CDN and VIdeo Hosting
Delivering live content to large audiences is tough. Between choosing the right hardware, encoders, and online video solutions, there’s a lot to think about. However, one thing that’s for certain is that fast, reliable, streaming experiences are essential for success. As we explained, one of the biggest challenges with sending content over large distances is packet loss. This issue is especially problematic for live streaming video as data is sent “packet by packet” in real-time. Any loss (above a minimum threshold) can reduce performance and downgrade quality for subscribers.
Adding CDN capabilities to your live streams significantly reduces packet loss. Employing worldwide distribution servers means a fast, reliable connection (and plenty of bandwidth) is always available to meet user demand. Consider this: marketing research finds that 80% of viewers would rather watch live video than read a blog and 82% prefer video to social posts. 67% of online viewers say that quality is the most important aspect of live stream content.
The demand for video hosting and streaming capabilities is increasing by leaps and bounds every day. With this, the demand for a CDN video server can’t help but follow the trend. We’re pretty sure that you’re here to find out which service is the best CDN that can boost your website’s video streaming and hosting capabilities. Without a doubt, the decision to buy CDN for your site is a bit tricky these days.
But even with this little dilemma, CDN services are truly amazing. With servers that are strategically placed all over the world, a CDN video server can deliver your high-quality video content to your audience wherever they are in the world. This feat is possible through a CDN provider’s multiple servers that act as multiple streams for your content to further boost the speed of your contents’ delivery. With this kind of efficiency, a CDN video server can surely improve both the quality of your website’s service and its reputation.
