Televes in the world

Diversification and internationalization

Moscow, Dubai, Barcelona or Cartagena de Indias (Colombia) are some of the places where Televes had a leading participation during the first quarter of the year. The company has worked intensively at the decision-making level of the different sectors in which it participates.

Thus, the social and health care development CareLife was presented at the Mobile World Congress in Barcelona, while the TRITON solution for port and coast service management was one of the main features at the Dubai Boat Show. At the CSTB in Moscow, the CABSAT (back in Dubai) and the Colombian Andina Link, the message was oriented towards the developments for the Hospitality sector, communication infrastructures and the classic catalogue for the radio and television signal reception and distribution, the classic side of an increasingly international and diverse company.

An x-ray of the radio-frequency spectrum until 2030

Brussels guarantees the regulatory environment of the spectrum until 2030, allowing the appropriate space for the development of the different technologies present.

In a proposal published last January in Brussels, the European Commission took notice of the importance of securing the 694 MHz-to-790 MHz band for the provision of broadband services to ensure connectivity as part of its Digital Single Market (DSM), encouraging Member States to liberalize that band in a coordinated manner.

This same resolution describes the spectrum as a public asset and sets the 470MHz-to-694 MHz band exclusively for TDT broadcasting services in primary mode, and for PMSE (Program Making Specific Equipment) in secondary mode until 2030.

The resolution highlights the fact that both the TDT and the PMSE sectors require “regulatory predictability” based on the availability of enough spectrum for the development of services - specifically of FTA (Free To Air) television - while ensuring space for its own investments in order to meet the European audiovisual policy objectives in terms of social cohesion, pluralism and cultural diversity.

This resolution - agreed among the European Commission, the European Parliament and the European Council - is welcomed by the sector, since it will provide the television industry with legal protection and allow the investments required for the second Digital Dividend, as well as the development of a technology still to contribute a great deal to the audiovisual sector.

In this respect, projects such as WiB or recent EWS (Emergency Warning System) reveal that the broadcasting sector keeps evolving and that broadcasting will still be a key player in the connected world, due to its intrinsic advantage of one-to-many transmission in any location and under any circumstances.

Next issues of this newsletter will keep you posted on these projects.

FAQs

Why am I not able to program an AVANT9 using my Android tablet?

One of the big new features included in AVANT9 is the configuration capacity by means of ASuite.

The expert says

AVANT9 programming by means of an Android device - either tablet or mobile phone - requires an OTG cable (included in the multiband amplifier's package). The USB connection of an Android device does not function as a computer's; this is the reason why OTG is used to enable communication between a mobile device and an USB device (pen drive, keyboard, etc.).

Its use is not arbitrary and allows a single mode: micro-USB connection to Android and female USB connection to the AVANT9 (see figure). Some Android devices are not compatible with the OTG extension. Should this be the case (check terminal compatibility with OTG) it still can be programmed by means of the ASuite application for Windows.

Check asuite.televes.com for any questions regarding AVANT9 and ASuite.

Encoder operating parameters

Television sets have a limited mode for interpreting the configuration of video and audio digital services. Televes encoders have a wide compatibility range

In an encoder, video is characterized by means of a combination of parameters, such as resolution, mode, and frame rate. Thus, 1080p60 is interpreted as a signal with 1080 horizontal lines, progressive mode, and 60 frames/second.

Resolution
Television sets still measure their screens in terms of horizontal and vertical lines. The combination of both numbers (1920x1080, for example) will give us the total number of pixels of the image: 1920Vlinx1080Hlin = 2,073,600 pixels.

Mode
It defines the way in which information is transmitted (pixels). When all the lines in the square (frame) are transmitted, we call it progressive (“p”) mode. When transmission is divided into odd and even line packets, we call it interleaving mode (“i”).

Frame Rate
The frame rate is the information flow measured as the number of squares per second. The square, or frame, can be divided into fields when the odd and the even lines are considered. The Frame Rate parameter is thus directly proportional to the perceived quality:

  • 1080p/60 Enhanced video frame rate: it represents a 1080-line square every 1/60 seconds.
  • 1080p/30 Standard live or recorded video frame rate: it represents a 1080-line square (odd and even lines) every 1/30 seconds.
  • 1080p/24 Standard motion picture film: it represents a 1080-line square (odd and even lines) every 1/24 seconds.

For all interleaving mode (“i”) cases, the squares are assumed to include either odd or even lines.

For 1080i/60 a 540-line (odd or even) field every 1/60 seconds is produced, which generates a 1080-line image every1/30 seconds.

Besides the image quantification parameters, there is also the way in which the image is coded (codec). Televes encoders include two types of codecs: MPEG2 and H.264/MPEG-4 AVC.

Encoder configuration
Based on their inputs, there are two types of encoders. SD encoders - with CVBS inputs only - support both 480i60 and 576i50 resolutions. HD encoders have video inputs per component (YPbPr); besides the mentioned SD resolutions, they support 480p60, 576p50, 720p50, 720p60, 1080i50, 1080i60, 1080p50, and 1080p60. Those including HDMI input support the resolutions above and 1080p24.

Encoders currently have multiple configuration options, most notably the Video Codec and Max Output Resolution tabs. Besides the traditional Video Codec (MPEG2 and H264) options, new values are added in the coding profiles for H264 (Image 1).

For Max Output Resolution, changing the coded service resolution to adapt to the installation receivers is now allowed (Image 2).

When it comes to checking encoder configuration, having a strong signal and the capability to change resolution prove to be very useful. zAs HD is a signal generator capable of performing this function (Image 3).

The output resolution configured and provided by the encoder can be checked using a field strength meter (Image 4).

AVANT9 PRO: the best programming is no programming

One of the new features implemented in AVANT9 is the Automatic programming function*. By means of a tuner, the unit performs a filter automatic programming followed by an adjustment at the level required to avoid intermodulation.

Based on a set of default parameters, a channel scanning is performed for the unit to self-configure and adjust.

The scanning is carried out on all connected UHF and VHF inputs. All channel frequencies are covered with a tuner, which detects the DVB-T signals with the required quality and a minimum reception level of 60dBμV. The different channels found for each UHF input are subsequently assigned to the filters. The assignment prioritizes UHF, and the order followed goes from Filter 1 to 10. Each individual channel found is assigned a single filter; the consecutive channels are assigned to that same filter until a maximum of 7 channels is reached.

Once this operation complete, the UHF2 multiplexes are assigned, followed by the UHF3. Once self-installation complete, the multiband amplifier performs the adjustment process with the obtained configuration parameters.

This function makes AVANT9 a Plug & Play device, because… the best programming is no programming.

* The self-installation mode is available on PRO and PROSAT models (Ref. 532021 and 532031).
