FAQs - Preguntas frecuentes

Why occasionally is not possible to watch some DTT channels trough an encoder?
Features of the A/V signal could affect the output signal.


Sometimes is not possible to reach the performance expected when trying to have a DTT HD channel from a HDMI source.

Usually this problem is caused by a lack of awareness of the TV features. Some TV models are High Definition (1920 x 1080p) compatible just through a HDMI source which means that their tuner is not able to receive a DTT HD signal.

To sum up, your encoder is likely to be working fine but the problem is normally caused by the resolution of the A/V signal. Therefore the solution would be to adjust the resolution of the HDMI or A/V source so that the DTT signal will also  have a lower resolution (for example 1280 x 720p)  










It is very remarkable the accuracy of  mock-ups.

In the picture, this realism is reflected in the mockups of a train station with a satellite dish installation. There is no greater realism than this dish with its characteristic orange

The unstoppable evolution towards data networks

Transmission protocols, both in wired and wireless networks, evolve in parallel 
with the growing demand end users have for data services

While the mobile telephony sector continues assimilating current 4G LTE deployments, the next 5G generation, which will represent a quantum leap in capability for users, is being evaluated. Wired networks are also advancing rapidly; GPON grows to TWDM and XGPON to provide greater capacity, DOCSIS 3.1 provides an alternative to fiber optic deployments up to 1 Gbps, and extends binary possibilities for twisted pair deployments.

But also broadcast networks are gearing up to become more efficient in data transmission, as is the case of DVBS2 and DVBC2.

DVB-S2 is a broadcasting technology that works very closely to the theoretical limit of maximum bit capacity for a given quality ratio. Because of the increasing demands for greater capacity for internet users, the DVB defined the requirements that eventually led to a single standard, called DVB-S2X, which was finally published in 2014. It is a profound enhancement of the DVB-S2 spectral utilization, with 116 combinations of modulation and FEC, audio, video and data in IP format, as well as offering the possibility of "bonding" transponders to increase the bit rate.

Regarding the evolution of the DVB-C, many of the commercial requirements for DVB-C2 were approved as a mirror image of its DVB-S2 twin brother, for instance increasing 30% of overall capacity. But it also includes more specific requirements for cable networks, such as techniques to improve the efficiency of IP data transport, the integration of low cost "edge QAM" type solutions, or low latency for distribution of interactive services. The definitive DVB-C2 specification is based on COFDM (multicarrier) with guard interval and QAM modulation for the individual carriers, which differs significantly from DVB-C, single carrier.

Technology trends are all aimed at offering end users an increasing flow of data both wired and wireless, either fiber, coaxial cable, or twisted pair, to enable services and applications that we are just now beginning to know, but very soon will become the ´day to day´of our augmented reality: Internet of Things, Smart Cities, Digital Homes, Telecare and Teleprevention, OTT or Ultra High Definition    





The versatility of the Nevo range and the importance of output impedance

The versatility of the switch cascade/standalone and high/low gain the difference in the Nevo range

Televes's multiswitches are manufactured with the latest technology, high quality components and a high stardard quality control. Televes is loyal to the company philosophy "European technology designed and made in Europe".

With NEVO, Televes has increased its range of multiswitches with 5, 9 13 and 17 inputs.

All the products in this range meet the stantandard A class for screening with excellent technical features.

The multiswitches can be configured as cascade or stand-alone with the flick of a switch. This mecanism makes it possible to  adapt the multiswitches to different installations. 

Any other multiswitch in the market needs to use terminal loads in any unused output. Unfortunately the installer sometimes forgets this so the installation is not optimized. However thanks to the adaptability of the Nevo the installation work is easier. All the products of the Nevo range are supplied with the output impedances  activated, this means that when the installer receives the multiswitch, it is ready to use it as terminal.

This innovation made by Televes  makes it possible to save time and money as usually the installer will need a terminal load ref. 4058 to complete the installation. This is not necesary with the Nevo range.

Some of the highlights of this new range are the zamak-made chasis (improved screening), the small size of the product and a low  power comsumption.

The multiswitches 9, 13 and 17 have a different power supply (732101 and 732801, both 12V output and maximun current 0.8A and 2.75A respectively), they are ideal for projects that require return path and a switch to choose between Low and High gain for the satellite feeds. All these features give to the Nevo range the reliability that makes the difference in the market.

Finally it is worth mentioning that the range includes multiswitches of 1 to 4 satellite inputs and up to 32 outputs. Also the range is suitable for small or big installations   



Sabía que ... ...Televes started using microchip technology in 1986?


Just  a year earlier Europe had begun to receive the first integrated circuit units. A very selected group of companies had sufficient technological capacity to utilise these small packaged computer circuits made out of semi-conducting materials in their industrial manufacturing processes. Televes begun to incorporate this technology in the SAT 90 line of amplifiers, achieving reliability levels that had never been seen before.  The founding layers were being set for cutting-edge industrial development that remains the core nature of our company´s philosophy thirty years later.  




Wall bracket to hold a CoaxData Gateway Ref.769301

Sometimes it is necessary to do a installation in a very specific location.

Usually in hotels, schools, small shops, etc.  there are a WiFi access points in a fitted comunal area.


The CoaxData Gateway can be fitted on  tables or be attached to it using one of the accesories included in the product. However, now there is a new accesory ref. 640301 that allows to us to install it on a wall. This new bracket makes it also suitable to be fitted in public spaces  



Fibre optic Triple play through a GPON solution in Oregon (USA)


In Corvallis, a town in the State of Oregon, a new fibre optic installation with a GPON solution has been done  in a student accomodation called "The Retreat at Corvallis".

This installation feeds 400 users thanks to the OLT512 ref. 769401 and 346 units of the ONT ref. 769502.  There is also a possibility to use Video Overlay in the 1.550nm window
