Commonly Used GPS-Related Acronyms
A2DP/ ATSC/CAN/ CCD camera/CDC/CMOS camera/CE Approval/ DVB-T / FCC Approval / FDA approval/ GPS/ OSD/ PIP display/ RDS/ SD card/TMC/TFT LCD
Advanced Audio Distribution Profile. This profile defines how high quality audio (stereo or mono) can be streamed from one device to another over a Bluetooth connection. For example, music streamed from a mobile phone to a wireless headset or car audio.
CAN
CAN-bus or CAN, short for Controller Area Network, is a technology first used in automotive applications, designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer.CANbus systems exhibit high transfer rates up to 1Mbit/s and high data transmission reliability. Simply speaking, it is a wire through which you could control your DVD player by your steering wheel control.
CCD camera
A charge coupled device (CCD) camera is an apparatus which is designed to convert optical brightness into electrical amplitude signals using aplurality of CCDs, and then reproduce the image of a subject using the electric signals without time restriction. When used in image applications, the charge collected and stored in each gate of the array represents a picture element or pixel of an image. A CCD is normally used for the image pickup device of a digital camera. Image data captured by it is stored in a storage medium such as a compact flash memory or an IC memory card. To monitor the captured image, a display means such as an LCD (liquid crystal display) isgenerally equipped in the digital still camera.
CDC
CDC refers to CD changers. A CD changer holds multiple Compact Discs, usually in a cartridge, and allows the user to access (or play) any of them, one at a time. CD changers are commonly found in home cinema systems, cars, and less often in computer equipment.
Complementary metal–oxide–semiconductor (CMOS) is a technology for making integrated circuits. A CMOS image sensor is a device that converts an optical image into electrical signals using MOS (metal oxide semiconductor) transistors. In the imaging field, CMOS image sensors have proved to be less expensive to manufacture relative to CCD imaging devices. The primary advantages of CMOS imagers are their relatively low cost generally resulting from the use of standard,high-volume CMOS processes and their ability to be integrated with native CMOS electronics for control and image processing.
ATSC is a set of standards developed by the Advanced Television Systems Committee for digital television transmission that replaced much of the analog NTSC television system on June 12, 2009 in the United States and will replace NTSC by August 31, 2011 in Canada and December 31, 2021 in Mexico.
CE Approval
The CE marking (also known as CE mark) is a mandatory conformity mark on many products placed on the single market in the European Economic Area (EEA). The CE marking certifies that a product has met EU consumer safety, health or environmental requirements.
Abbreviation for Digital Video Broadcasting—Terrestrial; it is the DVB European-based consortium standard for the broadcast transmission of digital terrestrial television.
FCC Approval
The Federal Communications Commission (FCC) is an independent United States government agency. The FCC was established by the Communications Act of 1934 and is charged with regulating interstate and international communications by radio, television, wire, satellite and cable. The FCC’s jurisdiction covers the 50 states, the District of Columbia, and U.S. possessions.
FDA approval
The Food and Drug Administration (FDA or USFDA) is an agency of the United States Department of Health and Human Services and is responsible for regulating and supervising the safety of foods, dietary supplements, drugs, vaccines, biological medical products, blood products, medical devices, radiation-emitting devices, veterinary products, and cosmetics. The FDA also enforces section 361 of the Public Health Service Act and the associated regulations, including sanitation requirements on interstate travel as well as specific rules for control of disease on products ranging from pet turtles to semen donations for assisted reproductive medicine techniques.
The Global Positioning System (GPS) is a global navigation satellite system (GNSS) developed by the United States Department of Defense and managed by the United States Air Force 50th Space Wing. It is the only fully functional GNSS in the world, can be used freely by anyone, anywhere, and is often used by civilians for navigation purposes. It uses a constellation of between 24 and 32 medium Earth orbit satellites that transmit precise radiowave signals, which allow GPS receivers to determine their current location, the time, and their velocity. Its official name is NAVSTAR GPS. Although NAVSTAR is not an acronym, a few backronyms have been created for it.
OSD
On-screen display, a feature of visual devices like VCRs and DVD players that displays program, position, and setting data on a connected TV or computer display.
Picture in Picture (PiP) is a feature of some television receivers and similar devices. One program (channel) is displayed on the full TV screen at the same time as one or more other programs are displayed in inset windows. Sound is usually from the main program only.
Radio Data System is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts. The RDS system standardises several types of information transmitted, including time, station identification and programme information.
Secure Digital (SD) is a non-volatile memory card format developed by Matsushita, SanDisk, and Toshiba for use in portable devices. Today it is widely used in digital cameras, handheld computers, PDAs, Media Players, mobile phones, GPS receivers, and video game consoles. Standard SD card capacities range from 1 MB to 4 GB. The capacity range for high capacity SDHC cards overlap slightly, beginning at 4 GB but reaching as high as 32 GB as of mid-2009. The SDXC (eXtended Capacity), a new specification announced at the 2009 Consumer Electronics Show, will allow for up to 2 TB capacity cards.
TMC, for Traffic Message Channel, is a great way to get Traffic issues sent to your GPS via FM signals that can’t be picked up by a normal FM car stereo. TMC is a specific application of the RDS or Radio Data System for silently transmitting information like traffic and weather over FM signals.
Thin Film Transistor-Liquid Crystal Display, a special kind of field-effect transistor made by depositing thin films of a semiconductor active layer as well as the dielectric layer and metallic contacts over a supporting substrate. Transistors are embedded within the panel itself, reducing crosstalk between pixels and improving image stability.
