tv inputComprehensive Analysis
Television is a telecommunication system for broadcasting and receiving moving pictures and sound over a distance and also refer to all the aspects of television from the television set (or Internet) to the programming and transmission. The word is derived from mixed Latin and Greek roots, meaning "far sight": Greek τῆλε "tele", far, and Latin visio-n, sight (from video, vis- to see). A television sytem may be made up of components, so a screen which lacks an internal tuner is called a monitor rather than a television. A television may be built to receive different broadcast or video formats such as HDTV
..." 2) "Input" -- As to tv input1in·putPronunciation: 'in-"put Function: noun 1 : something that is put in: as a : an amount put in <increased input of fertilizer increases crop yield> b : power or energy put into a machine or system for storage, conversion in kind, or conversion of characteristics usually with the intent of sizable recovery in the form of output c : a component of production (as land, labor, or raw materials) d : information fed into a data processing system or computer e : ADVICE, OPINION, COMMENT f : a stimulus that acts on and is integrated into a bodily system <sensory input> 2 : the means by which or the point at which an input (as of energy, material, or data) is made 3 : the act or process of putting in Pronunciation Symbols Input is the term denoting either an entrance or changes which are inserted into a system and which activate/modify a process. It is an abstract concept, used in the modeling, system(s) design and system(s) exploitation. It is usually connected with other terms, e.g., input variable, input parameter, input value, input signal, input device and input file. From the most general systemics perspective, input is a subjective concept and depends on how the system is used. In such sense, the same system can have different inputs in different applications. In the case of a process description/model, the concept input is closely connected with the concept output. Here, what enters is called input and what exits is called output. Example: For an abstract system A(x,y,p), where x,y are variables and p is a parameter, x may denote input (variable) and y may denote the output for a process: y = f(p,x), but, for another goal/(system application), the system A can be the carrier of a process x = g(p,y), where y is an input and x is an output.[citation needed] Usually, in the modeling of a problem/process, input are these variables which are known and output are those unknown to us yet. In recognition that the quality of the input can be crucial to the value of the output, a famous saying teaches us "Garbage IN, Garbage OUT" (GIGO). http://www.google.com/search?hl=en&q=define%3A+GIGO&btnG=Google+Search In different contexts, input has several more concrete domain-dependent meanings.
In information processing, input refers to either information received or the process of receiving it:
