What is DLNA

DLNA is a joint venture between Intel, Microsoft and Sony. It is a set of standards that will allow compatible devices to transmit and receive any media files (photo, audio, video) over a wired or wireless Internet network, as well as play them online. In other words, it is a technology for connecting TVs, computers, digital cameras, printers, smartphones and other consumer electronics into a single network. Using DLNA, we send photos and videos taken to a mobile phone to the TV screen without unnecessary wires. We send photos from a digital camera directly to the printer. Thanks to the same option, we listen to our favorite music from the tablet through the computer speakers, etc.

Note! With the Digital Living Network Alliance technology, all media content is streamed, and there is no need to wait until the files are fully downloaded to play them.

DLNA Devices and Support

All devices that comply with DLNA standards are conventionally divided into 3 groups:

  1. The first group includes all household network devices . These include TVs, video players, audio systems, stereos, printers, network storage, etc. By their functionality, devices are divided into media players (DMP), media servers (DMS), media players (DMP), media controllers (DMC) and media renderers (DMR).
  2. The second group is mobile devices : phones, portable players, cameras and camcorders, pocket computers, etc. Mobile devices are divided into the following classes in terms of functionality: mobile media players, media servers, downloaders, transmitters and controllers.
  3. The third group unites all household multifunctional devices . This includes devices that support additional communication standards and convert data formats.

All DLNA-certified devices carry the corresponding “DLNA Certified” logo. Today it is about 4.5 billion devices from more than 250 manufacturers. Modern personal computers and laptops, regardless of their operating system, are also DLNA-compatible. But, working with them to exchange data via the protocol, you first need to install the profile software that is loaded from the network.

Important! For a successful exchange of media files, both devices must support the DLNA protocol.

How DLNA Technology Works

Two compatible devices are involved in the exchange of content using the DLNA protocol: a server and a DLNA client or player. A server is a device that stores and transfers any media content to the second. To automatically transfer data to DLNA devices, the server is set up to share media files for devices in the homegroup. A client or player is a device that receives and plays the received files. Most often, TVs, audio and video players act as the client. Some devices are combined into a single network automatically. To work with others, you will need a simple initial setup, which we will discuss below. A prerequisite for the DLNA protocol is the connection of all devices to the Internet. File exchange will be carried out exactly on it.

Important! To transfer data, all devices must be connected to a single home network. Otherwise, you will not be able to use the DLNA option.

DLNA function on TV

DLNA is built into most modern TVs. To find out if it is supported on your device, refer to the user manual, or find the information you need on the official DLNA website. To transfer data via DLNA, the TV must be connected to the router:

  • over a Wi-Fi network;
  • or using an internet cable.

Note! When transferring heavy files to the TV, a wired (Ethernet) connection is recommended. This will avoid loss of streaming data and system crashes.

For a wired connection of the TV to the router, you will need an Internet cable. One end of the wire connects to the TV’s LAN jack, the other to the same connector on the router. Wireless TV connection will help you to install a built-in or external Wi-Fi adapter. The latter is purchased additionally, and is inserted into the USB connector. The router to which the devices are connected must support the DLNA protocol. Once a DLNA connection has been established, the TV screen will display playable folders.

Note! For the convenience of displaying and playing media files on TV, it is recommended to pre-sort all data into folders (for example, by category or artist). You can also use the LCN (Logical Channel Number) function on your TV, which sorts the channels in a convenient order.

Many SAMSUNG smart TVs are equipped with not only DLNA option, but also Plug and Play standard. UPnP also enables device sharing on a single network, but shows less flexibility in the choice of content providers. In most cases, UPnP and DLNA devices are compatible. AllShare and PC Share Manager programs have been developed for Samsung based on Tizen. The proprietary PC Share Manager software unites a TV and a computer or laptop into a single network, and also makes it possible to play multimedia data from a media server on TV. The program is compatible with all generations of Samsung TVs with DLNA support. We configure the PC Share Manager using the following algorithm:

  1. Download and run the software on your computer from the official Samsung website.
  2. In the explorer, which is located on the left, we find the necessary folders with media files.
  3. We mark them.DLNA technology - what is it in a TV, setting up a server and data transfer
