Diskusia k téme DRM (Digital Radio Mondiale)
The DRM Energy Efficiency Calculator is the DRM Consortium user-friendly tool that determines how much energy can be saved by switching transmitters from analogue to digital DRM operation.
The parameters considered are: operational mode, time on-air, and broadcasting technique assessing the energy consumption and electricity costs, based upon local market information. By comparing data sets for both analogue and DRM digital operations, it can estimate the potential (and often huge) savings broadcasters might expect from switching over to DRM. This shows how this new digital technology can reduce electricity bills by double-digit percentages and proves how DRM supports broadcasters’ efforts to become more sustainable though green technology.
Sprava je HOAX. To len tupci mozu sirit dalej.
Zaujimave! Kazdopadne, prekazkou zostava nedostatok prijimacov.
Situaciu ale mozu pomoct zmenit RUSI, INDOVIA a dalsi...
Tak uz aj pre DRM na FM.

v Európe nemá. Tu sa tlačí 25ročné európske bábätko DAB lebo tak !
Porovnanie DRM: 200kHz kanál, možnosť vysielať 1 až 2 programy. DAB: 1,5MHz kanál, 10 až 20 programov. "Výhodou" DAB je že stanice budú nahnané do multiplexov monoplných prevádzkovateľov namiesto toho, aby prevádzkovali vlastné vysielače.
ma podla vas DRM radio este nejaku buducnost?
ps- a co tak porovnat DRM vs. DAB/DAB+ ?
Nahodou som narazil na aplikaciu, ktora dekoduje DRM30 z SDR donglu. Ide o celkom cerstvu aplikaciu, zatial si ju stiahlo < 10 ludi. Nepiste mi, ze je to zbytocnost, ja o nu zaujem nemam, len davam do pozozrnosti.
