FAQs - Preguntas frecuentes

How to download H30FLEX meter's measurements?


A quick and easy way to display measurements on the PC.

The expert says

The first thing is to connect the H30FLEX meter to the computer using the USB. The driver that recognizes the H30FLEX is usually installed automatically and so the meter is immediately detected. Otherwise it will have to be manually installed (instructions can be found in the “Driver installation“ section, from 3.1 to 3.8, in page 18 of the manual):  en.televes.com/H30FLEX_manual

Once the driver is installed, you will need to open a browser (Chrome is recommended), type http://h30.flex in the address bar, and press Enter. The first window (1) of the web application will be displayed, where you will have to select the Measurements option in the menu bar.

This window will display all the Datalogs stored in the H30FLEX, grouped by dates and standards (DVB-T, DVB-T2, DVB-S, DVB-S2, analogue...). Measurements can be displayed in calendar mode (2) as well as in list mode (3). They can all be selected at once for deletion or export.

The Datalog download to the computer is carried out using the buttons on the top right side; the format used is xls. Each Datalog will produce a file; whenever multiple files are selected, they will all be downloaded into a single compressed .zip file. To display all the data associated with the Datalog measurements you only need to click on the name, and a new window will pop up (4)

Optical LNB installation

All the tips and tricks for an appropriate implementation.


The connector is one of the most sensitive elements in an optical installation, since it is prone to multiple losses.  Knowing how to differentiate an angled physical contact (APC) from a 0° straight one (PC or UPC) is essential. Differentiation is easy, since an APC connector (Angled Physical Contact), with an 8° angle is always green. As a rule, always put together connectors with the same angle to avoid high losses or even the absence of signal.

The Televes optical LNB are used as straight connectors (PC or UPC: Physical or Ultra Physical Contact) and as FC type connectors (Ferrule Connector), namely connectors with a screw system that keeps the ferrule into place.

It is crucial to consider that system-compatible fibre must be single-mode (SM) instead of multimode fibre (MM). Single-mode fibre allows for longer distances than multimode fibre, since a single light mode is propagated in parallel with the fibre's axis.

PC contact APC contact

Fitting connectors based on finish

 

The optical LNB have an optical output power of 7 ±2 dBm. Optical converters usually work in the 0 dBm to -15 dBm range. If you take the direct output signal of the optical LNB to the converter, it will saturate. The signal will have to be attenuated until an optical power inside the converter's operating range is achieved. To this end, the use of attenuators will always be required, provided that there are no other split, connector or cable losses between LNB and converter (only in the 0.3 dB/1000 m range). Televes provides three FC/PC connector attenuators with 5 dB, 10 dB, and 15 dB losses respectively (References: 2364, 2365, and 2366 respectively).

 

Ferrule finish types

 

To be considered during installation:
1) The optical LNB is powered through the coaxial cable. It is recommended to protect the connector with an F cap to ensure tightness.
2) Optical connectors are always provided with a protective cap. Given the ferrule they are meant to protect is very sensitive, it is recommended not to remove the cap until the connection will actually take place, to avoid dirt that could result in transmission losses.
3) Due to the ferrule's high sensitivity, never apply any load or make any contact on it.
4) The connector must fit straight into the groove as shown in the picture

Ideas

ArantiaCast solution for Hospitality


One of the most popular ways of multimedia content consumption is using an Internet connection and a wireless device, such as a smartphone or a tablet. In such cases, the screen size represents a serious handicap; this is why there are options allowing the content projection on a television set.

Casting is a solution that, rather than projecting the smartphone screen on the television set, actually projects the application that is being executed. Once an app is initiated on the smartphone, it can be sent to Chromecast, which takes care of its execution from then on, freeing the mobile device and allowing it to receive calls or execute other applications.

The Google Chromecast-based casting is compatible with over 1,000 applications.

ArantiaCast is a streaming system that allows each user in a multiuser environment, such as hotels, to have its own exclusive Chromecast associated device. Without any login or password, and with automatic disconnection when the hotel host checks out through the hotel's PMS

Sabía que ... ...Televes won the gold medal in the Belgium International Inventors Fair, back in 1969?

In the digital communication era, messages devoid of content are easily produced. However, Televes remains true to its innate condition of developing technologies that improve the audiovisual experience in the home.  

There are documented facts, like the one that took place back in 1969, when the Televes Multiband antenna was awarded the gold medal and the Big Price in the XVIII International Inventors Fair held in Brussels. The picture shows the diploma, the medal, and the trophy we received and remember today as one of the first international acknowledgements of our capacity for innovation

HEVC, the last frontier of video compression development

The last stage in the evolution of video compression systems from MPEG2 (1995) to H.264 (2003) is HEVC, approved in 2013.

 

HEVC achieves an almost 50% reduction in bit rate as compared with its predecessor, H.264

HEVC is the outcome of the joint effort of ITU Video Codification Experts Group and ISO/IEC MPEG (Moving Pictures Experts Group). The first facilitates telecommunication standard creation and adoption, while ISO/IEC manages the standards for the electronic industries.

HEVC is the inevitable successor of H. 264 for video encoding, and was designed following a planned evolution for video encoding. The benefits obtained from HEVC are indeed significant, since it provides an average reduction in bit rate of 50% for a given video quality as compared with H.264, a higher video quality for similar bit rates, or a better interoperability, optimized using a specific syntax that simplifies implementation.

There are multiple and obvious applications for HEVC. First, for streaming on mobile devices. A bit rate reduction of almost 50% translates into a direct reduction in the distribution cost of mobile operators. For a given video quality, they will not have to deliver the same amount of data as they do today with H.264. Together with the new streaming techniques (HLS, DASH), HEVC will boost OTT (Over The Top) video distribution platforms, complementing linear video distribution. The mobile devices' hardware will be able to decode HEVC, obviously.

Furthermore, HEVC also contributes to the development of 4K and 8K high-resolution video. Considering, for example, that 4K resolution requires handling four times as many pixels as a resolution of 1080 p, the efficiency provided by HEVC makes 4K broadcasting using DTT or satellite come true.

HEVC is a big step forward in video compression technology. It provides an additional set of tools and algorithms, while providing parallel processing capabilities for efficiency optimization, allowing for higher quality and resolution video streams, and improvements as compared with current coding systems; basically, providing a quantified improvement in the quality of user experience.

Applications for HEVC coding will emerge in multiple fields, such as broadcasting (DTT, cable, and satellite), IPTV distribution, or video surveillance systems
