FAQ

What does DVB-T mean?

It stands for “Digitally video Broadcasting-Terrestrial“ and is the digital aerial television. It is like DVB-S (“Satellite” for the digital satellite transference) and DVB-C (“Cable” for the digital cable transference).

Can DVB-T be received over the existing antenna system?

Yes. Depending on condition various optimizations could be necessary (e.g. level customization, equalization, exchange of the channel amplifiers or filters, new orientation of the receive antennas and others). The reception of the main programs of the RAI usually requires an own receiving antenna for the television band III. All other programs, as well as those of the RAS, are receivable with a broadband antenna for the TV bands IV and V.

How can I rearrange the DVB-T channels on the receiver?

First you should do a channel search (normally in: Menu/Settings/Transmitter search mode/Automatic/Start/Storing/Ok/Exit). After the storage these programs can be sorted in their order according to your wish (in: Menu/Settings/Transmitter search mode/Automatic/Start/Storing/Ok/Exit).

Is the electrosmog increased by DVB-T?

No, because this new digital transference technology requires a lower broadcasting achievement to guarantee a flawless reception.

Can I record with my video recorder furthermore?

Yes, because it is able to record external sources (such as a DVB-T receiver) by means of the “Scart”-interface. But for the time you must choose either “AUX” or “AV” (instead of a program number) on the video recorder. However, both the DVB-T receiver and the video recorder must be programmed.

What are the advantages of DVB-T?

Less electrosmog (EMV) and thus energy savings, less interferences and disturbances, better frequency and canal use, improved illumination of shadow zones, an improved picture and sound quality, a raised program offer, mobile television, additional services (MHP, EPG, title, description and duration of the running broadcasting), possibility for the interactivity, same canal nets, transmissions in HD quality, multi channel clay method (AC3 for cinema Atmosphere), use for 3D-television.

Does DVB-T also transfer teletext?

Yes, beside the teletext a variety of additional service data will also be transferred.

What does SD quality mean with DVB-T?

SD means „standard definition“ (like in the analogous television) and has a resolution of 720 x 576 pixels in 16:9 formats (it corresponds to 0.4 Megapixel).

What does HD quality mean with DVB-T?

HD means “High Definition“ and has a resolution of up to 1920×1080 pixels (it corresponds to “Full HD” and 2.1 Megapixel). HD receivers have an integrated digital receiver which can return MPEG4 (H.264, for high-resolution (high definition) programs).

Which interface must my television have to represent HD signals form external sources?

It must be able of HD. That means that it should dispose, provided that already a HD decoder is not integrated, of at least one DVI or of a HDMI connection.

Which features must my DVB-T decoder have to represent high-resolution (high-definition) HD programs?

It must be HD compatibly (provided with the MPEG4 / H264 – Codec).

Which connection do I need for HD-TV?

Best of all is the “HDMI” – connection which can transfer a data rate up to 5 GBIT/s. “DVI” or “YUV” – connections show a lower data rate and a restricted functionality.

Which video-resolution (format) do the programs of the RAS have in “HD”?

The resolution is 1280 x 720p (“p” stands for “progressive” and means 50 full images per second).

Can I receive “Dolby Digital” through DVB-T?

Yes, the digital AC3-format (with five audio channels) is emitted, provided that is contained in the program.

Will hearing films also be transferred for blind people and visually impaired people?

Yes, the transmission through the stereo sound and the audiodescription linked with it is possible with DVB-T. It is still the respective program supplier to chose whether it offer this service or not.

Can I also hear radio programs through DVB-T?

Yes, provided that the supplier also transfers radio programs in the broadcasting block.

Can I receive DVB-T also in the car?

Yes, provided that the broadcasting net is laid out for it and you dispose of a suitable DVB-T receiver unit in the car.

Does DVB-T also support “VPS”?

No, because “VPS” was developed for analog television. DVB-T uses, instead, the electronic program leader EPG with which you can comfortably program admissions if a permanent memory medium exists.

Can I browse the internet with DVB-T?

Yes, television sets with the “HbbTV” logo link television programs with the internet contents in order to receive additional information about the broadcasting.

Why do I sometimes hear no audio on various programs?

This is only a question of setting. In the TV menu select settings, audio, stereo tone or tone fashion 1 (or A) and store it. If this does not help, it could be necessary to deactivate „Dolby Digitally AC3“. Some devices own an audiokey on the remote control for these options.

Can I receive DVB-T programs of the RAS for free and everywhere?

Yes, provided that the reception place is covered, that the receiver unit is compatibly and that the signal of the roof antenna fulfils the minimum qualitative requirements. There can be restrictions with an internal or mobile reception, because this kind of receptions require a lot of higher broadcasting power.

Are there differences in quality among DVB-T receivers?

Yes, numerous differences were ascertained in the input sensitivity, sturgeon firmness, program stability, lip synchrony, the software errors and the power consumption.

What is DVB-T2?

It is an evolution of DVB-T. With the publication of the new standard in September 2009 improvements in canal efficiency, robustness, cover, flexibility and the additional services became aimed. With DVB-t only 4 TV programs in SD format or 3 TV programs in HD format can be transferred in one channel. Through DVB-T2 it will be possible to transfer at least 8 TV programs in SD format and about 5 programs in HD format on one TV channel.

Is my DVB-T receiver also able to receive DVB-T2 programs?

No, it must be replaced with a new appliance.

Can I receive DVB-T programs with a new DVB-T2 receiver furthermore?

Yes, because the new appliances receive both standards.
