Ancillary Data
Ancillary data is data that has been added to given data and uses the same form of transport. Common examples are cover art images for media files or streams, or digital data added to radio or television broadcasts. Television Ancillary data (commonly abbreviated as ANC data), in the context of television systems, refers to a means which by non-video information (such as audio, other forms of essence, and metadata) may be ''embedded'' within the serial digital interface. Ancillary data is standardized by SMPTE as ''SMPTE 291M: Ancillary Data Packet and Space Formatting''. Ancillary data can be located in non-picture portions of horizontal scan lines, known as Horizontal ANCillary data (HANC). Ancillary data can also be located in non-picture regions of the video frame, known as Vertical ANCillary data (VANC). Technical details Location Ancillary data packets may be located anywhere within a serial digital data stream, with the following exceptions: * They should not be located ...

Observer (meteorological)
A meteorological observer, or weather observer, is a person authorized by a weather authority to make or record meteorological observations. They are technicians who are responsible for the accurate observation, rapid measurement, timely collection, recording, and timely submission of meteorological parameters and information and various atmospheric phenomena to the Meteorological Center. Surface, upper air, radar, and satellite are all forms of weather observations. Role Meteorological observers play a key role in many flood, drought, environmental and water resources applications. Whilst rainfall observations are most widely used, other parameters of interest include air temperatures, humidity and wind speeds. The main measurement techniques include raingauges, weather stations and weather radar, with satellite precipitation estimates playing an important role in data-sparse regions. METARs are generated by both government-owned and privately contracted facilities. The coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of United States Navy Ratings
United States Navy ratings are general enlisted occupations used by the U.S. Navy since the 18th century, which denote the specific skills and abilities of the sailor. Each naval rating has its own specialty badge, which is worn on the left sleeve of dress uniforms of enlisted personnel. U.S. naval ratings are the equivalent of military occupational specialty codes (MOS codes) used by the United States Army and the United States Marine Corps, the ratings system used by the United States Coast Guard, and Air Force Specialty Codes (AFSC) used by the United States Air Force and United States Space Force. Ratings should not be confused with ''rates'', which are used to identify personnel of specific a rating and pay grade. For example, if a sailor has the pay-grade of E-5 (petty officer second class) and the rating of boatswain's mate, then combining the two—boatswain's mate second class (BM2)—defines both pay grade and rating in formal address or epistolary salutation.

Nautical Chart
A nautical chart or hydrographic chart is a graphic representation of a sea region or water body and adjacent coasts or river bank, banks. Depending on the scale (map), scale of the chart, it may show depths of water (bathymetry) and heights of land (topography), natural features of the seabed, details of the coastline, navigational hazards, locations of natural and human-made aids to navigation, information on tides and Ocean current, currents, local details of the Earth's magnetic field, and human-made structures such as harbor, harbours, buildings, and bridges. Nautical charts are essential tools for marine navigation; many countries require vessels, especially commercial ships, to carry them. Nautical charting may take the form of charts printed on paper (raster navigational charts) or computerized electronic navigational charts.

Codes
In communications and information processing, code is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form, sometimes shortened or secret, for communication through a communication channel or storage in a storage medium. An early example is an invention of language, which enabled a person, through speech, to communicate what they thought, saw, heard, or felt to others. But speech limits the range of communication to the distance a voice can carry and limits the audience to those present when the speech is uttered. The invention of writing, which converted spoken language into visual symbols, extended the range of communication across space and time. The process of encoding converts information from a source into symbols for communication or storage. Decoding is the reverse process, converting code symbols back into a form that the recipient understands, such as English, Spanish, etc. One reason for coding is to enab ...
