We are beginning with Media Server 101. The word of “media” is the plural of Latin word “medium” which means environment or tool(1). Even though it has been used in many domains, it is mostly encountered in the communication domain both socially and technically. Media is all of the devices and methods used in storing information in several formats and delivering it to masses. It can be generally classified into two main categories as printed (newpapers, publications etc.) and digital (cinema, radio, television etc.). In this blog post, we will mention the media server which processes and transfers digital media.
What Is Media Server ?
Before answering “What is media server?”, it is better to mention about video which is a leading digital media type as a result of electronic devices getting popular, increasing speed of internet access and people’s changing habits on social communication, also about the role of video in total commucation traffic and future vision of video.
When we review the Monthly Internet Data Transmission graph in Figure 1 prepared based on the Cisco VNI 2016 data, it is seen that the video is in the first place among the dataflow worldwide both in nowadays and in future. For example; while video data traffic is about 40 ExaByte (1 million TB) by year of 2016, it is predicted that this number will be about 110 ExaByte in 2020. Another detail in this graph is that the increasing acceleration of media. For example; although all types of media has an increasing trend, the acceleration rate of video is obviously a lot more higher, and this increases the part of video among total data.
Media Server Ecosystem
Another point that should be investigated is that the financial reflection of video market which dominates the dataflow. According to the financial data prepared by Statista in Figure 2, while the market size of video was 7.5 billion $ in 2014, it is predicted that it will be doubled as nearly 13.7 billion $ in 2020. We can clearly infer from the two graphs that audio and especially video have a very important role on all types of media both in qualitative and in quantitative ways. This massive increase both in data size and in financial market affects directly all components in this ecosystem (content providers, advertising sector, hardware producers, media server market etc.) in a positive way.
What are Media Server Usage Areas ?
Media server is a complete hardware and software solution which provide a flexible infrastructure for live and recorded audio/video streams in different formats for different kinds of sectors although it can be specialized in technical functions.As an example of today’s applications, media servers work in digital IP television broadcasts, in popular video websites, in music platforms with millions of users, and even in infrastructure of systems recording and processing camera recordings.
In this start-up blog post, we have mentioned what media servers basically do without technical details and given information about the ecosystem with regard to today’s and future data of digital media. In our next posts, we will share other components in this ecosystem and technical details of media servers.
