DLNA:
The abbreviations DLNA are the abbreviation of Digital Living Network Alliance, a standard to which are subscribed more than 250 companies of technology and whose mission is to be able to share contents in network from any device, regardless of the mark or model. Compatible devices can be of all types, including routers, televisions, hard disks, mobile phones, computers, etc., although they need to be connected to a local network by WiFi or Ethernet.
In general there are three basic types of computers with different roles within a DLNA network: a server in which to host the multimedia files (a network hard disk, a computer, or the mobile itself etc.), a player that will play the contents (In our case the phone) and a renderer (a screen or sound equipment). Since they are all within the same network, the detection should be automatic (or almost) and only have to be sectioned in the terminal by which device we want to play the video or sound file.
Chromecast:
Google's most popular device that has recently reached version 2 featuring a revamped design, a new, more powerful processor and a three-antenna configuration for WiFi dual-band AC. It allows direct screen mirroring from compatible Android terminals and you can enjoy the games and applications of the big screen phone.
In addition, in one of its latest updates, the AllCast feature has been added to the iTunes store, so it is also possible to stream content stored on an iPhone and iPad to a Chromecast, as well as share files from services such as Dropbox and Google Drive.
