The transition to 4K in DTT is still very early in our country. Considering that we still have channels that do not even reach HD resolution, The transition to 4K still seems far away, despite the tests and advances made in the last few years. But we seem to be making slow progress, and the proof of this is the tests conducted on TV in the Community of Valencia.

Istec company, which is affiliated to the Ministry of Finance and Economy Model, through its official blog. First pilot tests to offer programming in 4K via DTT. In this way, they will start with the entire metropolitan area of ​​the city of Valencia, where they can enjoy this resolution through the number 41 quadrant. said resolution.

Valencian Community will have a special DTT dial for 4K

According to Istec, they have the support of the Ministry of Economic Affairs and Digital Transformation to carry out these tests, and in addition to Valencia, they plan to conduct two more pilot tests in each provincial capital, which also make users Alicante and Castellón. la Plana can also see progress through a special channel enabled for this.

Arcadi Spain, Minister of Finance and Economic Model, with this pilot test “Generalitat has been shown to have a network infrastructure capable of carrying and disseminating new technology services and demonstrates the adaptive power it needs to incorporate experimental services into telecommunications networks.“.

The content of UHD broadcasts in the Community of Valencia is encoded in HVEC via the Sivac-one real-time encoder developed by Sapec. Encoding is performed at a delay of less than 120 ms, with a consumption of less than 25 W per encoder module.

Currently, there are standard definition (SD) and high definition (HD) channels in DTT in our country. By law, however, all networks are required to broadcast in HD from 2023. Regarding 4K UHD, due to the bandwidth requirement, it is necessary to adopt the DVB-T2 transmission standard instead of the currently used DVB-T.

To play broadcasts over the DVB-T2 standard, we need a codec that complies with this standardSomething that has been on all 4K televisions since 2016. Instead, so that the user does not depend on this codec, there is a half-way alternative that has been working for some time, DVB-I, which makes use of IPTV content.
