General Information
UHD DTT and DAB+ digital radio need an industry push in Europe
With the advance of telecommunications, it is necessary to adapt existing infrastructures in order to be up to date and offer quality services. Therefore, the headquarters of Televes Corporation, in Santiago de Compostela, has been responsible for hosting the briefing by RTVE on the progress of UHD broadcasts in DTT and DAB + for digital radio, also with the assistance of Cellnex Telecom, Retegal, sectoral and business associations, SETELECO (Secretary of State for Telecommunications) and the General Secretariat of Media of the Xunta Galicia.
The reason for this event to be held at our facilities is due to the leadership of our main companies, Televes, TRedess and Gsertel in the design and manufacture of products for the development of electronic communications infrastructures in buildings and homes. In his speech, Santiago Rey, CEO of Televes Corporation stressed that in order to carry out projects for the deployment of digital terrestrial television in UHD and digital radio in DAB+ it is necessary the push of all the actors in the sector.
For this reason, investment must be made in these projects, as radio and television should be universal, free and freely accessible media, ensuring the democratisation of audiovisual content, which is currently being threatened by the limitation of frequency ranges for use in other sectors.
Moreover, the loss of progress in this sector has been openly discussed. Ángel García Castillejo, Director of Audiovisual Policies at RTVE, reflected on the importance of audiovisual communication as a tool for social cohesion. Above all, he stressed that the technology for this advance is available and the philosophy of companies should be to unify advances worldwide so that no country is left behind.
Javier Sánchez, head of strategy at RTVE's Innovation Centre, spoke further about DAB+ and warned that without a technical plan for the deployment of DAB+, piracy of broadcasts could increase, outside of any regulation or control.
The companies of the Corporation, TRedess, Televes and Gsertel have specialised in designing and manufacturing equipment for the transmission, distribution and measurement of radio and television signals for more than 60 years. This makes them understand that the leap to UHD broadcasting in DTT and DAB+ in digital radio is the best way to guarantee the future of free content for a cohesive population
The sector is urgently calling for the deployment of UHD content on DTT and DAB+ for digital radio.

DAB Radio: A leap into the future of Spanish radio
DAB (Digital Audio Broadcasting) radio is taking Europe by storm as the natural evolution of traditional radio, bringing a superior listening experience and a greater variety of content to listeners.
Clear, interference-free, CD-like sound, a wider choice of stations and specialised programmes, and even additional services such as information and interaction are some of the advantages that DAB offers listeners. For broadcasters, DAB means optimising resources thanks to spectral efficiency and zero interference with FM radio. In addition, new business opportunities open up through the transmission of additional data.
To guarantee the quality of the DAB signal throughout the Operator's network, Gsertel offers technological solutions such as the RCS DAB/DAB+ probe and the Hexylon portable meter.
The RCS DAB/DAB+ probe performs 24/7 proactive monitoring, automatically detecting any signal anomalies. Meanwhile, the Hexylon handheld meter comprehensively analyses the DAB signal, including measurements, echo and constellation analysis, as well as parameters such as transmitter ID.
DAB represents an important step into the future of broadcasting, with the potential to transform the way we consume radio. Gsertel, with its experience and commitment, is ready to support broadcasters in this transition and contribute to the development of a more modern, varied and enriching radio
Our people
David Goldar Director of Televes Middle East (TME)
The impact of the escalating violence in the Gaza region affects the normal flow of global shipping and the company's business.
With the escalating armed conflict in the Middle East, concern for the welfare of our colleagues in the TME subsidiary has become paramount. In order to better understand how these events are directly impacting their operations, we interviewed our director to get a firsthand view of the facts and the steps they are taking to address the current challenges
Could you explain how the current events in Gaza are affecting TME's subsidiary?
Of course. It is affecting us in two significant ways. First, any uncertainty, especially in regions with a history of geopolitical instability, affects our business. We have experienced this before, such as in Syria, where our efforts to develop the market were frustrated by the civil war. Similarly, our concern now lies in the possible spread of the conflict to areas where we are growing our business, such as Iraq.
How are global shipping disruptions affecting your operations?
Disruptions in global shipping, especially due to attacks in Yemeni waters and in the Red Sea, are a shared concern for us. We have observed that transit times for containers from Spain have doubled, mainly due to lack of space on vessels and longer routes around South Africa. This affects our ability to receive materials on time, especially for projects involving multiple products.
What measures is TME taking to mitigate the impact of these challenges?
We are proactively reviewing our requirements for the coming months and trying to anticipate them by bringing in materials earlier. However, it is a challenging task, especially in a subsidiary where a significant part of sales is project-based and covers multiple products

How to improve road safety at zebra crossings
The prevention of pedestrian accidents at zebra crossings is a priority road safety challenge. Lack of visibility of pedestrians and possible carelessness of drivers are critical factors contributing to these risky situations.
An effective solution to minimise accidents and protect citizens is the sensorisation of lighting installed at zebra crossings. By equipping the fixtures with motion sensors, it is possible to automatically raise the lighting level in the walking zone when people are detected on the pavement. This increased contrast at the required time effectively warns drivers that pedestrians are crossing. By ensuring the visibility of pedestrians, we can significantly reduce the risk of accidents on urban and interurban roads, while optimising the use of lighting.
Our CIES Crosswalk range combines CIES lighting with dedicated optics for pedestrian crossing lighting and highly sensitive motion sensors. These sensors, designed with a 180° angle, are activated when they detect people on the pavement, but ignore vehicles on the road. They also communicate with each other via Bluetooth to synchronise the lighting on both sides of the zebra crossing and activate simultaneously. This is an intelligent alternative for illuminating pedestrian crossings and enhancing public safety
FAQs
What is CRI and why is it important in lighting projects?
The term CRI, which is closely linked to LED lighting, stands for Colour Rendering Index. This parameter measures the accuracy with which a light source is able to faithfully reproduce the colours of objects. Its value is given in comparison to a reference light source, which would be the sun (black body radiator), and is expressed on a scale from 0 to 100, where a higher CRI means better colour rendering. The CRI depends on the spectral composition of the light emitted by the source, not on the colour temperature itself. However, two light sources must have the same colour temperature for their CRIs to be comparable.
To measure the CRI, 8 chromatic samples, called Ra, ranging from R1 to R8, are analysed. Each R-sample is given a score from 0 to 100 according to the naturalness of the colour compared to how it would appear under the reference light source. The CRI is obtained from the average of these Ra values. There is an extension of the metric, where in addition to these 8 pastel shades, additional samples with more saturated colour are considered, up to a total of 14 samples (R1 to R14).
There are other metrics to measure colour rendering such as the TM-30 (with 99 samples), but the CRI is still the most common and widespread on the market.
The CRI is therefore a parameter to be known and considered in terms of the impact of light on colour accuracy. While a high CRI is in demand for task-oriented or indoor lighting, CRI values between 70 and 80 are more than adequate for ambient lighting and outdoor lighting. Knowing the influence of CRI on lighting will improve decision making that will influence the visual experience of projects

Sanasaryan Han, a Luxury Collection Hotel (Istanbul, Turkey)
The Sanasaryan Han hotel, from Marriott's Luxury Collection hotel range, becomes the first IPTV project in collaboration with Marriott to be carried out by Televes in Turkey.
This hotel has a privileged location in the tourist centre of Istanbul, a country where tourism is expected to grow exponentially. Therefore, this project is a milestone for Televes as it places us among the best options for future projects such as those we are already negotiating.
It is also important to highlight the important challenge of entering the Turkish market, one of the most complex and competitive, and to have achieved it by introducing the complete range of Hospitality solutions, as is the case of the OLT512EVO.
The OLT512EVO is the main equipment deployed in this project. It consists of an Optical Line Terminal that allows the distribution of IP services over optical fibre using the GPON protocol. The importance of this module is due to, on the one hand, its ability to offer up to 16 services per ONT to provide establishments with a wider range of entertainment, and on the other hand, its capacity to serve 64 subscribers through a single fibre for each of the PON interfaces, achieving the connection of up to 512 optical subscriber terminals in total

How to perform a complete deployment in just 10 steps with our OLT512EVO
Specially designed for Hospitality, this OLT speeds up the installation process of FTTH systems.
Our OLT512EVO offers intuitive configuration via a simple and consistent web interface. This provides great flexibility in the implementation and deployment of Hospitality services.
Thanks to its specific functionalities, we can create a GPON infrastructure adapted to the real needs of the hotel sector, and deploy up to 16 services on the same ONT. We will perform all the configuration on the OLT512EVO, following 10 simple steps:
Verification phase
We access the web interface to register and visualise the ONTs of the installation.
We visualise the optical powers to check the physical state of the network and detect possible irregularities in the fibre.
Provisioning phase
We define the VLANs to be propagated in the GPON network, taking into account that we can deploy up to 16 VLANs in the same ONT.
We define and assign bandwidth (BW) profiles per service and per ONT.
We create GPON services using VLAN pairs and their associated bandwidth profile.
We associate GPON services by different profiles, depending on the different groups of ONTs previously defined by the hotel.
With a single click, we apply the profile that best suits each ONT.
Configuration phase
We configure the ONTs with a backup associated to each profile, which will be recorded in the OLT to facilitate the task.
We establish the specific parameters of each ONT, depending on the previously established needs.
Monitoring phase
We monitor the installation to ensure that we have successfully configured it.
Thanks to real-time information on the interface and the physical state of the network, as well as the alarm system, we know what is happening before, during and after deployment
