DVB-T Rhein-Neckar is a DVB-T broadcast region in southwest Germany.

history

The Rhine-Neckar metropolitan region , the seventh largest economic area in Germany with 2.4 million inhabitants, became the first DVB-T transmission region in south-west Germany on May 17, 2006 with the activation of the digital transmission system on the Königsstuhl . Five days later, on May 22nd, 2006, DVB-T operation began in the Stuttgart metropolitan region on the Stuttgart telecommunications tower in single-wave technology operation with the Königsstuhl transmitter. As of November 5, 2008, the single- frequency network with Stuttgart, and largely Würzberg (Odenwald), will be terminated, as new frequencies have been allocated to the Heidelberg location. DVB-T was introduced in the metropolitan region of Berlin in November 2002 and in October 2004 in the metropolitan region of Rhine-Main . The blatant delay was officially justified by the "difficult" topography in the north of Baden-Württemberg. Ultimately, the analogue transmitters were only equipped with DVB-T hardware, which resulted in a radio pause of 24 hours. It stands to reason that the delay was caused by a financial dispute between the state parliament , LFK and public broadcasters ( ARD , ZDF , SWR ). It was also hoped that the private program providers ( ProSiebenSat.1 Group , RTL Group ) would participate in the DVB-T start and the costs of the installations in Baden-Württemberg . However, the private program providers were not prepared to do this, as they understand that due to the changed legal situation and the now missing subsidies (new EU directives now prohibit public subsidies for DVB-T), DVB-T involvement in Rhein-Neckar with its 2, 4 million inhabitants (including the Stuttgart area 6 million) in no relation to the costs. In Berlin and Frankfurt am Main , these grants were granted to private program providers, thus encouraging these regions to adopt and maintain a different standpoint on the question of participation in DVB-T infrastructure costs, even after the subsidies had to be repaid.

Reception in the Rhine-Neckar area

Nationwide since May 2006

On May 17, 2006, just in time for the 2006 World Cup , the terrestrial broadcasting of television signals in the Rhine-Neckar region was digitized, i.e. switched to DVB-T and the analogue television channels switched off. Initially only from the Königstuhl (Heidelberg) together with the Stuttgart-Frauenkopf and from May 29, 2006 also partially together with Würzberg (Odenwald) until further DVB-T infrastructure was gradually put into operation. From November 5, 2006 to November 4, 2008, the channel distribution was different, namely ARD National (SWR) E50, ARD Regional (SWR) Baden-Württemberg E53, ZDF-mobil E27. The occupancy since November 5, 2008 can be found in the following table.

All channels transmit their EPG (Electronic Programming Guide) information for the next 7 days with DVB-T.

The DVB-T transmission power is 50 kW per transmitter, which is only 10% –50% of the output of the old analog TV transmission systems (100 kW – 500 kW) with the same range and better illumination of the valleys. This reduces energy consumption and the switch to DVB-T is therefore also advantageous from an economic point of view. The maximum range of the DVB-T signal is approx. 100–120 km if there are no obstacles in the way of the signal. Mountains or mountains, forests and high-rise buildings are considered obstacles. The main station is the Heidelberg TV tower on the Königsstuhl. Reception via an indoor antenna is possible in the core area around Mannheim , Ludwigshafen am Rhein , Heidelberg , Worms and Speyer . Reception is via the house antenna in the east as far as the Odenwald (far beyond the A 81), in the north as far as the Rhein-Main area (but limited by the mountains of the Odenwald in the north-north-east) West to the Palatinate Forest and in the south to far beyond Rastatt possible. The Stuttgart telecommunications tower is synchronized in the single-frequency network with the Königstuhl near Heidelberg. This z. B. in Heilbronn , Neckarsulm and Sinsheim the reception improved significantly. When the Heidelberg frequencies were changed on November 5, 2008, the SFN with Stuttgart was abolished, which worsened reception in the areas that overlap with Stuttgart.

In contrast to Berlin / Brandenburg, Rhine-Main and other DVB-T regions, the private broadcasters ( ProSiebenSat.1 Group and RTL Group ) do not participate in Baden-Württemberg . Channels such as RTL , Sat.1 , ProSieben or VOX can therefore not be received via the DVB-T Rhein-Neckar channels. Until April 20, 2007, RTL analog (PAL) was broadcast via the Heidelberg telecommunications tower , but with significantly less power (0.5 kW) than the public broadcasters (100–500 kW).

DVB-T Rhine-Main

→ Main article: DVB-T Rhein-Main , transmission systems on the Großer Feldberg

Due to the good reception conditions in the Upper Rhine Graben, the broadcasting systems Großer Feldberg and Hohe Wurzel (near Wiesbaden) of the DVB-T broadcasting area Rhein-Main radiate deep into the Rhein-Neckar area. The stations Großer Feldberg and Hohe Wurzel are about 80-100 km away. Topography and distance promote reception in the Rhine-Neckar area, and vice versa, reception of the signal from the Königstuhl transmitter is possible in the Rhine-Main area and in the Hessian Odenwald.

The for the Frankfurt Rhine-Main air digital TV channels offer with its 24 stations (as of July 2011, including private broadcasters) can therefore also have a north-facing vertically polarized roof antenna in Worms , Viernheim , Mannheim , Heidelberg , Ludwigshafen and Bruchsal be used . Anyone who enjoys a clear view to the north towards the Rhine-Main has a good chance of receiving a usable signal with an indoor antenna. But for that you have to be able to literally see the northern horizon. If this is not the case, e.g. For example, if the view is obscured by a forest, a small hill, a large building or similar obstacles, the signal from Rhine-Main cannot be received. Television signals, whether analog or digital, propagate in a relatively straight line. In comparison, the lower frequency VHF signals tend to bend around obstacles. Reflections on suitable objects may cause the signal to be received in situations without a direct line of sight.
