Content players for LED screens or LED players are the systems that reproduce and store the video and image contents for the LED screens. In them we create the playlists that will be played on the screens.
This functionality can be linked to a hardware (Asynchronous or Asynchronous Systems) or to a reproduction software (Synchronous or Synchronous systems).
These players have several operating options in common:
– Upload videos and images
– Schedule videos by calendar
– Screen brightness schedule
There is a wide variety of content reproduction systems for LED montiors on the market. Each of them has specific functionalities and there are even models that combine different types of features, including different ports for connection for video sources, internal memory, access and control through networks, among others.
The most common content players are: PC Software player, Asynchronous hardware player, Synchronous hardware player and Video processor scaler system.

In this type of systems, the player is fully integrated into the LED screen. These asynchronous systems are small electronic boards that are located inside the screen, that can be accessed via WiFi, direct connection through network cable or the Internet. There are hundreds of manufacturers that offer this type of systems for LED screens, 99% are of Asian origin. An asynchronous player is characterized by being able to play digital video contents stored in a memory (hard disk, USB pen drive, SD cards, etc.) without requiring a video source with an external player. Asynchronous players can have internal memory and additional USB connection ports for external memories.
As they are integrated into the screen it makes it easy for us to not have to rely on external content players.
The benefits of an asynchronous system are very limited and it is not possible to extend them, besides being a reproduction system of a specific manufacturer, you will be completely closed to the use of that application, as you won’t be able to choose any other in the future.
Asynchronous systems, being more basic systems than Synchronous systems, are used for small LED screens that do not require advanced use in the reproduction of their contents. For example:
– LED screens for pharmacies.
– LED screens for shops and stores with very repetitive advertising.
In addition to the usual brightness and power control functions, they allow the creation of playlists and automated programs to play content at specific dates and times. Asynchronous players usually have specific control software to be able to program their advanced functions, compatible with multiple types of image and video files (jpg, png, tif, gif, avi, wmv, mp4, etc.).
Some asynchronous player models can incorporate specific functions for network control, sensor control and control of electronics, and even with video ports for synchronous mode operation.
In LED screens, the Synchronous system refers to the system by which an external source is necessary. This means, that the screen integrates a digital video or data input on which it is necessary to connect a video source player.
The main advantage of these systems is the freedom to connect any player device to LED screens, as if it were a conventional TV with external video input.
Synchronous systems use a small element called a signal converting card or Sending Card. This card performs the conversion of the HDMI or DVI input image signal and converts it so that the LED screen can reproduce it. This element, although of very small dimensions has to be located between the reproductive system and the LED screen.
A Synchronous system is usually used for LED screens that require the connection of external video signals such as:
– Live applications (connection of video cameras)
– Connection of television signals (DTT, Satellite…)
– Content players (digital Signage)
