DLNA devices for Tv

DLNA (Digital Living Network Alliance) is wireless technology intervenes. Since always, the reproduction of content on a television screen, or through a sound system, has required the use of cables with HDMI, RCA, coaxial, 3.5mm jack or optical connection. The use of cables is a very traditional way, and continues to connect Blue-ray and DVD players, and even other less conventional devices, to televisions and compact sound systems to enjoy music and movies in the living room or home in a room. What would happen if we removed the cables and let the content “move” through the air?

Sony promoted the organization Digital Living Network Alliance in 2003 with the intention of establishing interoperability between different wireless devices with multimedia capabilities. The DLNA technology, which takes advantage of UPnP (Universal Plug and Play), establishes the connection between devices connected to the same Wi-Fi network: bluetooth connectivity, on the other hand, does not require being connected to private networks to share content, but a direct pairing input device and output device you can buy these gadgets from the gadgets pro under gadgets.


The use of the DLNA has important advantages from the point of view of the convenience of reproduction and access to the content to be reproduced, either at home or in the office. Why? This type of wireless technology avoids the need to copy the content to physical media such as a CD, DVD or USB memory, for example: the only condition, of course, is that the source device and the destination device are compatible with DLNA.

In today’s society it is usual to download and store digital content on the PC, and then copy it to physical units that can be used with a video / music player with a disc reader or USB devices. PCs are still today the main tools to enjoy entertainment, and their hard drives already have capacities that exceed Terabyte: enough space to store dozens of HD movies, hundreds of music albums and thousands of high-resolution photographs.

DLNA breaks the space limitation of DVD discs or USB memories, allowing access to all the content available on a computer, from a distance and with the simple use of a remote control. The user does not have to worry about copying the content to a unit that serves as intermediation, but simply to access it remotely and choose among all the files stored on the internal hard disk of a PC or connected multimedia hard disk.

DLNA technology is not only linked to the world of computing, but also to the world of mobile devices that live in our pocket and bags: tablets, MP4 players and Smartphones.

The DLNA also breaks with the physical limitations of the location of sources and reproduction units, as long as there is Wi-Fi coverage or access to the router through an ethernet cable connection: there are products that give access to a router through the use of the electricity network.

Smartphones and tablets have a large amount of digital content, whether hundreds of music albums that the user listens regularly, or videos and photographs taken with the camera of the terminal itself. Thanks to the DLNA, it is not necessary to start a PC to listen to the music you like most, but send it to a DLNA-compatible speaker, sound system or television that you have at home, that is connected to the user’s private Wi-Fi network .

The DLNA is the wireless solution for modern homes connected, a technology that allows you to share sound and visual content with total comfort, discarding the use of cables, and avoiding the intermediation of storage units. The DLNA offers total freedom of access and enjoyment of digital content, without the need for installation, to forgo the use of a source device for other activities, and without loss of time.

This wireless technology is important because it offers virtually instantaneous access to content stored on a device, connecting audio / video equipment from home to consumer products rich in multimedia content.
