Autofahrer-Rundfunk-Informationssystem
Autofahrer-Rundfunk-Informationssystem (ARI, German for: Automotive-Driver's-Broadcasting-Information) was a system for indicating the presence of traffic information in FM broadcasts used by the German ARD network of FM radio stations from 1974. Developed jointly by IRT and Blaupunkt, it indicated the presence of traffic announcements through manipulation of the 57 kHz subcarrier of the station's FM signal. ARI was rendered obsolete by the more modern Radio Data System and the ARD stopped broadcasting ARI signals on March 1, 2005. Functionality description SK signal The SK signal is actually the 57 kHz subcarrier that is transmitted by the ARI-compliant FM station for this functionality. This frequency, like the RDS subcarrier frequency is chosen because it is the third harmonic of the 19 kHz pilot tone used in the FM-stereo transmission standard. An easy way to understand that is that this frequency is the 19 kHz pilot tone multiplied by 3. An ARI-equip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institut Für Rundfunktechnik
The GmbH (IRT) (''Institute for Broadcasting Technology Ltd.'') was a research centre of German broadcasters ( ARD / ZDF / DLR), Austria's broadcaster ( ORF) and the Swiss public broadcaster ( SRG / SSR). It was responsible for research on broadcasting technology. It was founded in 1956 and was located in Munich, Germany. They invented or were influential in the research, development and field-testing of important standards such as ARI, RDS, VPS, DSR, DAB and DVB-T. was a founding member of the Hybrid Broadcast Broadband TV (HbbTV) consortium of broadcasting and Internet industry companies that established an open European standard (called HbbTV) for hybrid set-top boxes for the reception of broadcast TV and broadband multimedia applications with a single user interface. In 2020, ZDF and then other supporters indicated that they planned to withdraw from the organization, so the IRT was closed by the end of 2020.

Blaupunkt
Blaupunkt GmbH () was a German manufacturer, producing mostly car-audio gear and other electronic equipment. Owned by Robert Bosch GmbH from 1933 until 1 March 2009, it was sold to Aurelius AG of Germany. It filed for bankruptcy in late 2015 with liquidation proceedings completed in early 2016. The brand, now managed by GIP Development SARL of Luxembourg, is licensed for use by various product groups worldwide such as Air fryers. History Founded in 1924 in Berlin as "Ideal," the company was acquired by Robert Bosch AG in 1933. In 1938 it changed its name to "Blaupunkt", German for "blue point" or "blue dot", after the blue dot painted onto its headphones that had passed quality control. After World War II, Blaupunkt moved its headquarters and production to Hildesheim. Blaupunkt took over a former Philips/ Grundig factory in Portugal to produce automotive head units. It is still owned and operated by Bosch, used exclusively to make OEM units for car manufacturers and 24V ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Data System
Radio Data System (RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM broadcasting, FM radio broadcasts. RDS standardizes several types of information transmitted, including time, station identification and program information. The standard began as a project of the European Broadcasting Union (EBU), but has since become an international standard of the International Electrotechnical Commission (IEC). Radio Broadcast Data System (RBDS) is the official name used for the U.S. version of RDS. The two standards are only slightly different, with receivers able to work with either system with only minor inconsistencies in the displayed data. Both versions carry data at 1,187.5 bits per second (about 1.2kbit/s) on a 57 kHz subcarrier, so there are exactly 48 cycles of subcarrier during every data bit. The RBDS/RDS subcarrier was set to the third harmonic of the 19 kHz FM stereo#Stereo FM, FM stereo pilot tone to mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Road Transport In Germany
A road is a thoroughfare used primarily for movement of traffic. Roads differ from streets, whose primary use is local access. They also differ from stroads, which combine the features of streets and roads. Most modern roads are paved. The words "road" and "street" are commonly considered to be interchangeable, but the distinction is important in urban design. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically, many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other ...

Radio Technology
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcast Engineering
Broadcast engineering or radio engineering is the field of electrical engineering, and now to some extent computer engineering and information technology, which deals with radio and television broadcasting. Audio engineering and RF engineering are also essential parts of broadcast engineering, being their own subsets of electrical engineering. Broadcast engineering involves both the studio and transmitter aspects (the entire airchain), as well as remote broadcasts. Every station has a broadcast engineer, though one may now serve an entire station group in a city. In small media markets the engineer may work on a contract basis for one or more stations as needed. Duties Modern duties of a broadcast engineer include maintaining broadcast automation systems for the studio and automatic transmission systems for the transmitter plant. There are also important duties regarding radio towers, which must be maintained with proper lighting and painting. Occasionally a station's eng ...
