The term MPEG DASH is not a new one for the video producers, broadcasters, live streamers, etc. but there is still a lack of understanding about what it is and the implications that it holds for the technological world in the years to come. If you are one such individual looking for more information about MPEG DASH, who is it suitable for, the difference between MPEG DASH and a range of other delivery standards, and the difference that it’ll make in the world of video streaming, then you have landed on the right page.
Be it video on demand or the video streaming services in general, the importance of a delivery standard is indispensable. A few years ago, Real-time Messaging Protocol (RTMP) by Adobe that made extensive use of flash was the standard for such services. The Flash-based protocols, however, have turned obsolete over time and has given way for other standards to make their mark in the market. One such standard is that of MPEG DASH.
An abbreviation for Dynamic Adaptive Streaming over HTTP (DASH), it is a delivery standard for video streaming services that is similar to HTTP dynamic streaming (HDS) and HTTP live streaming (HLS). It enables you to offer real-time live streaming to your audience without making a compromise in terms of the quality, minimize buffering as well as dropouts. There are similarities between a range of other media streaming protocols and MPEG DASH since an adaptive file delivery system is common to all of them.
How Does It Work?
With MPEG DASH technology, the video file is first broken down into multiple smaller chunks. These chunks are the duplicated and variable bit rates are used to encode each one of these. Afterward, the manifest files play a crucial role in the identification of different segments within these chunks of a single file. Then smaller chunks are then delivered to the point of viewing where it is reassembled for the user to be viewed. This entire process happens in real time.
Benefits Of Using MPEG Dash
There are multiple benefits associated with the use of MPEG DASH for video streaming services. The first and foremost benefit associated with the use of MPEG DASH is that its foundation is laid on HTTP. Almost all of the web content on the internet is currently delivered to the users via the HTTP. This has an implication that the standard web servers can be used to deliver MPEG DASH streams so your audience will be able to reap the benefits of maximum speed while you would be able to keep the expenditure at an absolute minimum. For any given bandwidth, MPEG DASH is considered to be significantly more efficient than any of the other commonly used delivery standards.
Another major benefit of using the MPEG DASH protocol is that it is widely supported by almost all of the commonly used smart devices, operating systems, or browsers. So it doesn’t matter if your audience is using an iOS device or an Android one, whether it’s on Windows operating system or MAC, they won’t be faced with failure to access the video stream that you have to offer. There is a minor downside, though. The format is not supported by the Safari browser which is the prominent one on the Apple devices. So while the user will be able to access the video stream via the Apple device, he will have to use a different browser than Safari.
There is no argument over the fact that the quality of your video stream is of paramount importance in determining how well your business will be able to keep its audience engaged with the broadcast and the overall image of the business that will be developed in their minds. Low-quality video is a matter of utmost dissatisfaction for the user who is more likely to leave the broadcast without receiving the message that it has to deliver. A significant benefit of using MPEG DASH is a peace of mind that your video is being delivered to the relevant audience at the best quality possible. This helps in creating a brand image among the users and make them more interested in whatever products or services does your business have to offer.
In simpler words, thanks to the multi-bitrate streaming capability, MPEG DASH ensures that all of your users are able to watch the video at the best quality that their respective internet connections can support at any given time. This is what helps a great deal in minimizing the lag or excessive buffering, both of which are greatly annoying for the user. It is absolutely fair to state that the MPEG DASH is a technology that is sufficiently powerful, absolutely convenient in terms of its implementation, and is entirely stable that renders it reliable for the content creators as well as for the user.
All in all, it won’t be wrong to conclude on a note that the MPEG DASH technology has been gaining broad recognition and applaud from the community of live streamers and broadcasters, be it the individuals or businesses as a whole. Thanks to the lower overheads and growing standardization, the protocol is only likely to get better and stronger with the passage of time. In the years to come, the adoption of this technology will be much wider in the world of internet. It is true that the technology is still in its evolving phase and it’s a long way to go before it becomes the delivery standard being used by everyone as a priority over HDS and HLS. But considering the benefits that it has to offer and the potential it shows for improvement, it is only a matter of time that it beats all other delivery standards to take the lead in the market. In the next one to two years, the future of MPEG DASH will be much clearer as the licensing costs are defined. For now, though, it is fair to state that it looks like DASH is certainly meant to be the next big thing.
