Put simply, a media server is usually a PC which can store your various media files such as photos, music, home movies and purchased movies. You can also install software to manage your media. Media servers can also hold specialized software to allow you access to internet media content not normally available from a web browser.
A good example of the latter is a software package called Playon (www.playon.tv). Once installed on your media server, Playon allows you to access a host of cable channels including ABC, NBC, CBS, FOX, Bravo, LMN and others. The ability to easily install plugins, allows to access channels like TVLand and NatGEO provided by third parties. Playon offers HD programming for a onetime cost. Playon transcodes (converts) your media at the media server, thus requiring a fairly high performance processor. CPU chips with a Passmark score over 2500 are recommended. Since Playon does not have a button available to tell you the Passmark score of your CPU, You have to find the chip information in Windows and look it up yourself. It is well worth the effort if you are building a server to have an idea of your server performance before you start buying components.
My favorite media server application is called Plex (https://plex.tv. It is an open source program that allows you to access your media content on tablets, smartphones, and PC’s from anywhere in the world. You can also share your media libraries with others very easily. There are also apps for Android, IOS and Roku.
These applications also have channels on the Roku devices. Allowing you to take your Roku box with you when you travel and watch your media content anywhere.
