In January 2023, the BOE finally announced the new digital television standard for Spain; this standard states: “Every digital multiplex, wherever located, must switch its broadcasts to high definition (HD). Before February 14, 2024.”
This means that all digital terrestrial TV channels will be available from that date. They only stream in “high definition quality” or “HD”and normal definition or “SD” channels disappear from the channel grid.
This “DTT blackout” has been in the making for some time, and now there are many television networks that have taken the opportunity to announce that their channels will be broadcast in standard quality. will disappear from the channel list. This forces users to need a television that supports at least HD resolutions.
There has been no such significant change in the national radio and television infrastructure since the closure of analogue television. It is recommended to prepare before February 14 So that this doesn’t surprise us.
As we can read on the Ministry’s website and on the BOE itself, the concept of “high resolution” in this case refers to the following fact: Posts will consist of a minimum of 1280 horizontal x 720 vertical pixels (active lines according to BOE) It has an aspect ratio of 16:9.
Unfortunately, this change does not mean that all broadcasts will now be broadcast in 1080p or 4K quality. We will continue to watch television channels in HD versions The only difference is that the possibility of seeing SD quality will disappear.
Regarding the video coding format, the system shall comply with the international telecommunications standard ITU-T Recommendation H.264: “Advanced video coding for general audiovisual services”, which is equivalent to the ISO/IEC 14496 standard.10, often referred to as H.264. /MPEG-4 AVC. Come on, there is no change in this regard either.
The elimination of SD channels will be a benefit, which means that telecommunication companies will now Increased bandwidth to improve infrastructure with other types of technology across the frequency spectrum. Additionally, emissions may also increase from then on. 5.1 multi-channel audio In addition to stereo, our equipment complies with the international standard ITU-R BS.1196-7, which allows the broadcasting of movies with surround sound and music programs with such sound, as long as it is compatible.
All we need at least to be prepared for this power outage is: A display and TV tuner that supports HD resolution. This has more or less been the norm for the last 15 years, but we are aware that many people still do not have these serial elements and continue to watch DTT channels on old televisions.
According to the Ministry, More than 98% of televisions in Spain currently comply with these requirementsWhile it doesn’t show how they extrapolate the data or whether they only consider equipment sold from certain dates, there may still be some TVs in our home that aren’t compatible.
What if my TV is not compatible with DTT in HD quality? We either buy another TV or we can opt for a more economical solution that involves purchasing an external decoder for HD DTT. This decoder will convert the signal to high definition at a resolution compatible for television.
If we receive DTT service via satellite (TDTSAT) using a decoder that only allows standard definition reception, we will need to replace it with an HD decoder to continue receiving DTT signals; this is something we can refer to on this web. page.
It is also worth noting that when that day comes and standard quality emissions disappear from the grid, We should retune our television and perform a new channel scan to complete the migration.
This new channel search can be a bit tedious for most people as you will have to reorder the channels. In Xataka Smart Home, we told you the tricks of organizing DTT channels easily. In this case, it may still be useful to you.
Therefore, if you meet all the conditions to watch DTT channels correctly when SD channels disappear, all you need to do is; will be to recalibrate your television So that you can continue to enjoy programming as before.
