How to choose a receiver

Many of you find it difficult to place your Freebox near your TV while the telephone line is at the other end of the house. There are very practical and inexpensive systems to deal with these constraints: Wireless Video Transmitters.

Here is an example of using such a device in the house, you can get an idea if you are hesitant.

Initial situation

  • We would like to use the Freeplayer or Freebox TV from the room.
  • We are in a two-story house.
  • The telephone line is on the ground floor, in the kitchen.
  • The TV is on the second floor, in the bedroom.

The idea of a long scart cable across the house is quickly abandoned: the walls are made of stone and cannot be pierced; and with a cable of this length, the loss of quality would be too important … Moreover, it would be impossible to control the Freebox with the remote control from the room.

Receiver buying guide

The receiver buying guide states that transmission device used throughout this folder is an entry-level set, compare with onkyo 646 vs 656.

Principle of operation

How it works?

The set consists of two almost identical boxes: a transmitter (to connect to the Freebox), and a digital video receiver (to connect behind the TV). An explanatory diagram is present on the box.

  1. Power supply
  2. On / Off switch
  3. Scart cable (the socket on this side is a 3.5 jack)
  4. Channel selection switch
  5. Infrared report
  6. Directional antenna

There are 3 channels available for wireless transmission. For example, if your neighbour has the same device at home, you can use a different channel to not mix the signals. Conversely, someone nearby who uses a compatible product on the same channel can receive the signal and watch TV … high-end models offer encryption to avoid this type of problematic situation that we can possibly meet in downtown.

Another indispensable check, the choice of the channel!

It is noted that depending on the immediate environment (walls, halogen lamp, television …), the signal of the best home theatre receiver can be clearer on this or that channel. If you use the transmitter to travel a short distance in an apartment, it will not matter much, but in the case of our house with thick stone walls, the change of channel had an immediate effect on the quality!

And the remote?

While the most athletic will come down the stairs at full speed to change channels, others will connect the small infrared transfer module

This is a very small box with an infrared diode that connects to the transmitter, and retransmits everything that is captured by the infrared receiver.

Thus, if we press a key on the remote control in the room, the box in the kitchen retransmits the Freebox signal infrared, and we can change channels without moving which is rather practical.

You will notice that all the infrared signals are retransmitted, so we can control all the infrared devices present in the kitchen from the room.


Although the transmitter used in this folder is a first price, the quality is similar to that of a cable Scart on the small TV of 36cm.

Sometimes there is a small vibration in the image, or a few horizontal streaks when subtitles are displayed, but it is derisory; In addition, with a high-end device and less extreme conditions of use, this type of slight inconvenience disappears, which makes the system very significant, even on the big screen. If you are thinking of what receiver do i need, go for digital sound system receiver.
