Wireless AV Senders
If you don't have a number of computers or games consoles distributing multimedia through your home, there are other ways of watching TV, DVDs etc in another room.
A Wireless AV sender is a device than connects to a set top box or Video playback device such as a Satellite Receiver, DVD Player, Video Players etc and will send this AV signal wirelessly to receiver device located in another room in your home. The receiver will then connect to a TV via a SCART or HDMI cable and using a universal remote control or a duplicate control device for your AV equipment, you can change channel on your satellite receiver, stop and start your DVD etc. It should be noted you can use more than one receiver at once but generally, all receivers will be limited to watching the same signal that is being broadcast from the sender device.
There are a number of manufacturers offering from a limited set of features and these are listed below.
SCART Connections:- The Sender devices is not just limited to connecting to a singal satellite receiver or DVD player. Some AV senders will have up to 4 Scart Connections allow you to watch and control upto 4 different devices from your receiver device.
Device Frequency:- The most common place AV senders operate in the 2.4Ghz range. The only problem is that a number of other deivces also operate in this range. This can lead to intermitent interference from laptops as they connect to a wireless router, static cause by wireless phones, childrens toys and worst of all Microwaves which can totally decimate the quality of your signal. Newer devices operate in the 5.8Ghz range. Since this is outside the normal wireless band which everything else is on, you will be more likely to have a stable and consitent picture.
Channels:- If you are seeing static or interference in your signal, some devices can change to channel they operate on within this 2.4Ghz spectrum. This will generally help but it depends on the number of wireless devices you have and what channel they also use.
