The problem is always the same: the TV is still fine but it is not ready for MPEG4 broadcasts or for the future DVB-T2 and therefore a decoder must be added.But those external black boxes are ugly to look at, and often you don't know where to put them due to lack of space.But the solution is there, and it is represented by those decoders that connect directly to the rear sockets of the TV, they cost more or less like other decoders but disappear from view.This type of decoder can be circumscribed into two large families, those that connect to the scart socket and those that are instead inserted into an HDMI input, specifying that the latter cannot take advantage of the bonus decoder.For both, there is the advantage that there is no need to purchase the connecting cable separately.These models fit into the scart sockets found on older televisions, with at least five years of life on their backs, and also fit on older kinescope TVs.They are not very small because they still have to adapt to the size of the scart and need an external power supply.The socket, on the other hand, is articulated to adapt to different televisions.Some also have HDMI output so they can also be used on newer televisions and can be attached to the back of the television with Velcro.To receive the remote control signal there is usually an external sensor that must be brought towards the front of the TV.This type of decoder is present in the price lists of all the most important brands, such as Digiquest or Telesystem;it is no mystery that they are generally made by the same oriental manufacturer and then branded with different brands and therefore have very similar characteristics while the remote controls could be different.Their list price is generally around 30-40 euros depending on the offers of the moment.These decoders plug into an HDMI socket on the TV and have the advantage of being able to be powered from a USB socket on the TV itself.They do not always need an external receiver for the remote control, some advanced models allow you to use only one remote control, that of the TV, for basic functions.Their dimensions are really small, a few cm long and less than a cm thick, with the convenience that once the TV is turned off they too turn off and therefore do not consume unnecessary power.In some cases the placement of the HDMI inputs on the TV can be a problem, often recessed in small areas that prevent direct insertion into the HDMI socket of the decoder or the connection of the antenna, but to overcome the problem a small adapter is usually provided to make installation more flexible;if you have this problem it is good to check that the adapter is supplied.HDMI decoders are available in two types, one of which is slightly smaller than the other, generally the smallest are distinguished by the antenna input with type F connector, not used in Italy, but with the adapter supplied. .The smaller decoders are for example those marked Strong or WWIO while among the larger ones (relatively speaking) we find the Diprogress already tested by DDay.it in the past.The list prices are also in this case between 30 and 40 euros except for further promotions.As with scart decoders, generally the manufacturer is always the same, who then marks the decoder with the different brands.There may be differences in the remote control, not all are the same.Copyright © 2022 DDay.it - ​​Scripta Manent publishing services srl - All rights reserved - VAT number 11967100154
