In computing, refers to an operating mode under which data is received, processed and the results returned so quickly as to seem instantaneous. In terms of streaming media, refers to content streamed live, or as-it-happens.
A loosely defined term in which a computer process occurs almost "instantaneously." For example, computers used in science laboratories to collect data and return the "massaged" data back within a few seconds for instant feedback to the student would be considered real-time processing.
Real-time is an immediate response by a computer system. Real-time can also refer to events simulated by a computer at the same speed that they would occur in real life. (www.mcpihome.com)
the actual time when something takes place.
A type of ultrasound that use still pictures to show movements, somewhat like a motion picture.
A term that refers to the nearly instantaneous transmission of information. Videoconferencing is an example of real-time technology at work.
Immediate rather than delayed. At normal speed.
adj. Of, or relating to, a time frame imposed by external constraints. Real-time operations are those in which the machine's activities match the human perception of time or those in which computer operations proceed at the same rate as a physical or external process. Real-time operations are characteristic of aircraft guidance systems, transaction-processing systems, scientific applications, and other areas in which a computer must respond to situations as they occur (for example, animating a graphic in a flight simulator or making corrections based on measurements).
The processing and visibility of transactions and information as they occur, and not on a periodic or batch basis.
Something that happens in real-time will keep up with the events around it and never give any sort of "please wait" message.
The measure of showing or playing streaming video or film immediately and without rendering.
The actual time in which a program or event takes place. In computing, real time refers to an operating mode under which data is received and processed and the results returned so quickly that the process appears instantaneous to the user. The term is also used to describe the process of simultaneous digitization and compression of audio and video information.
Delivered as it occurs. For example, a live broadcast is streamed across a network in real-time.
Refers to video recorded at the same speed as action occurs (so it may be played back at the speed of real time without drag). Real-time video is phased at 30 frames per second (60 fields per second) for NTSC video and 25 frames per second (50 fields per second) for PAL format equipment. Basically all VCR recorders record real-time video, but MOST digital DVR recorders do not. AutomatedSurveillance.com proudly offers DVR systems capable of both displaying AND recording real-time video for seamless recording of important action.
Input into a system that affects existing data immediately, as opposed to a batch-processed system that collects all data inputs and then processes them all at a later time. This is a common buzzword that indicates that data can be accessed or edited immediately.
The performance of a computation during the actual time that the related physical process transpires in order that results of the computations are useful in guiding the physical process.
Contrary to Batch, a real-time data collection computer or system is connected by wire or wireless to a host computer or system. As data is collected, it is transmitted directly to the host application.
The transaction is processed as soon as the shopper submits their payment. Back to the top
In business, this refers to the ability to know what is going on "right now" - in the present time, immediately as it happens. Traditional corporate performance and reporting solutions tend to be characterized by delays that make the data they provide to users out-of-date. PureShare applications provide real-time KPI monitoring, performance metrics and reports.
Meaning new or interactive, used in contrast to "batch." As a command or message is issued, it is executed or sent to its destination. For example, one of the requirements of OhioLINK was that it be updated in real-time, e.g. that a cataloging or circulation record would be immediately available on the system rather than placed in a buffer from which it would be added to the system overnight.
If a computer responds in 'human time' this is considered to be real-time. For example, if a computer model moves approximately at the speed that users expect without being jerky or not rendering properly, it is considered to be real-time. As this is hard to achieve, a range of techniques is used to create an illusion of real-time movement. A different definition of real-time relates to the currency of information. This definition might apply if a user moved around a computer model and expected it to render and change instantaneously to display up-to-date information. An example might be a traffic map which users can access to see the speed of the traffic in the part of the city that they want to navigate.
(broadcast usage) Actual time. The moment in which the event is occurring, as opposed to "reel" time or clock time when the event is replayed from tape. (See also: Backhaul, Live Origination)
A computer program that operates in real-time and it really matters. An aircraft's fly by wire is real-time. Many programmes are called real-time, however our definition is based around the idea that it must happen in real-time and a delay would be bad news, rather than just irritating.
Real time is a level of responsiveness that a user senses as sufficiently immediate or that enables a device to keep up with some external process (for example, Covers Wireless serves content as it happens).
The processing of data as soon as it is received, as opposed to batch processing.
The class of computations whose correctness depends not only on whether the result is the correct one, but also on the time at which the result is delivered. Real-time applications are those that perform any real-time computations.
'Live', 'As it happens'. Real-time systems pass entries, update records, accounts, balances, etc., immediately new data is received and make that data available to users within the limitations of the system. Typically, the response from the system will be measured in milli-seconds. If a real-time system is failing to present its response to users adequately fast, it may well be indicative of other bottlenecks, such as a saturated network or other processes competing for processor priority. A real time system is assumed to need immediate access to processor power and will have its priority set accordingly.
Real-time processing includes the immediate exchange of data and then immediate processing upon receipt. This is generally done for one borrower and one loan at a time. ELMNet uses XML (eXtended Markup Language) for the format of its real-time messages.
The Internet equivalent of a "live" broadcast, which allows participants to engage in a conversation on a subject-oriented channel.
A term used to describe any system which operates such that input, processing, and output take place over a short period of time and without any long delays or storage of input or of intermediate or final results.
The description for an operating system that responds to an external event within a short and predictable time frame. Unlike a batch or time-sharing operating system, a real-time operating system provides services or control to independent ongoing physical processes
Implies that information is updated with sufficient frequency that it should give a reasonable estimate of the current conditions. On this site, information is noted as "real-time" but may still demonstrate a certain amount of delay (from communcation delays, verification delays, etc).
is the notion of completing a computing task before the next task arrives as in algorithm processing
Having the appearance of immediate action. For example, typing messages that appear on another's monitor almost instantly.
Describes gameplay that happens without waiting for player input; ie. in "real time" and not turn-based. Mostly used in describing strategy and wargame/historical simulation games.
The term refers to the activities or processes that occur within the same time frame online. See synchronous.
no delay in processing requests and information, other than the time necessary to up- or download data over the Internet.
Describes an application that requires a program to respond to stimuli within some small upper limit of response time (typically, milli- or microseconds).
Without any delay. Some stockbroking systems only allow you to access prices which are delayed - they can be up to 20 minutes behind the actual prices at any moment. With Barclays Stockbrokers you can access real-time prices - the prices at which buying and selling is actually taking place in the market.
Events that happen in real-time are happening virtually at that particular moment. When consumers chat in a chat room or send an instant message, they are interacting in real-time.
Programs which allow interaction between users within a specified time, such as MUSES and IRC.
At the time it occurs or withoug lag in processing time other than the speed of electronic processing and transmission.
Time in which reporting on events or recording of events is simultaneous with the events. For example, the real time of a satellite is the time in which it simultaneously reports its environment as it encounters it; the real time of a computer is the time during which it is accepting data and performing operations on it.
Real-time refers to tasks that are time critical and must happen in our time. Real-time is the highest priority you can give to a thread or process in the Windows environment. Even though this is accounted for in the operating systems, Windows is a poor real-time OS. The user interface should always be real-time. If you move the mouse, your pointer should move on screen immediately. Unfortunately, Windows can bog down enough so that this doesn't happen. Other real-time applications can include medical applications and control of real world systems. For example, you want to make sure that the train switches tracks on time and not too late because your server is bogged down.
In the present. A real-time system that enables an immediate response to external events. Often used in relation to tracking; see also track-and-trace
Events and actions are taking place "as it happens". The time frame is "now". All Ecom Technology transactions take place in real-time.
No delay in the processing of requests for information, other than the time necessary for the data to travel over the Internet.
A reference to processes that generate results during the same time when the data is being obtained. For example, some analytical methods that can be analyzed in the field are referred to as providing real-time results.
Occurring immediately. The term is used to describe a number of different computer features. For example, real-time operating systems are systems that respond to input immediately.
In MIDI, there are two types of recording procedures: (1) real-time and (2) step-time. Real-time resembles traditional recording, where you play and it records. Step-time recording requires that you load each event or note one step at a time.
Where the correctness of a system's behavior depends not only on what happens in what order, but also on exactly when it happens. Ada has features that provide real-time support by allowing the programmer to control when an action will occur, to connect an action to a time-based trigger, and to schedule multiple tasks using strict priority-based FIFO scheduling to ensure that critical real-time deadlines are met.
Tasks that are time-critical and must happen in our time (as opposed to the much faster computer time). Real-time is the highest priority you can give...
1) Immediate response. The term may refer to fast transaction processing systems in business; however, it is normally used to refer to process control applications. For example, in avionics and space flight, real-time computers must respond instantly to signals sent to them. 2) Any electronic operation that is performed in the same time frame as its real-world counterpart. For example, it takes a fast computer to simulate complex, solid models moving on screen at the same rate they move in the real world. Real-time video transmission produces a live broadcast.
IEEE] Pertaining to a system or mode of operation in which computation is performed during the actual time that an external process occurs, in order that the computation results can be used to control. monitor, or respond in a timely manner to the external process. Contrast with batch.
The processing of data in a business application as it happens - as contrasted with storing data for input at a later time (batch processing).
The processing of information that returns a result so rapidly that the interaction appears to be instantaneous. Videoconferencing is an example of a real-time application. This kind of real-time information not only needs to be processed almost instantaneously, but it needs to arrive in the exact order it's sent. A delay between parts of a word, or the transmission of video frames out of sequence, makes the communication unintelligible.
refers to the rapid retrieval, processing and transmission of data
Immediate processing of input or notification of status.
An activity which occurs "while you wait", rather than being delayed for processing at a later time.
The reception, processing and delivery of data in such a way that it appears to be instantaneous.
The actual time during which physical events take place.
As it happens. All FTS products show you data, statistics and frame information as it is actually occurring on the circuit. You can also capture data to memory or to disc and review it later.
The immediate availability of data to an information system as a transaction or event occurs.
No lag time, no processing time. The ability of a computer to process data so fast that the user perceives no delay between initiating a task and seeing the result.
any process in which there is virtually no delay between events. Asking a question during a classroom discussion is done in real-time. Responding back to an earlier email is not. However, a virtual discussion group or whiteboard are synchronous and done in real-time.
A recording, or playing speed that shows things as they occur, between 24-30 frames per second.
The processing of information that returns a result so rapidly that the interaction appears to be instantaneous. Telephone calls and videoconferencing are examples of real-time applications. These kinds of real-time information not only need to be processed almost instantaneously, but it needs to arrive in the exact order it's sent. A delay between parts of a word, or the transmission of video frames out of sequence, makes the communication unintelligible. See also Synchronous.
Pertains to a data collecting system that controls an on-going process and delivers its outputs (or controls its inputs) not later than the time when these are needed for effective control.
Immediate happening, in the present moment. In computing, an electronic process, operation, or routine that occurs quickly enough to affect or respond to a related process taking place simultaneously in actual time.
Relating to imaging techniques, especially ultrasound, where the person performing the examination, can actually see the organs/body parts being examined as the examination is being done - as opposed to techniques where the signals have to be processed in some way before they can be interpreted. Real-time examinations are particularly valuable when examining moving organs like the heart. Still images can be made by selecting appropriate "movie frames" afterwards.
Instantaneous or very rapid response. For example, stockbrokers require real-time market quotes, but casual investors may be satisfied with Yahoo's 15 minute delayed quotes.
any process in which there is virtually no delay between events; user does not have to wait any appreciable time for event A to conclude before beginning event B
Transmission (i.e. for a video conference) without any sound or visual delays.
processing data and acting upon the results at the same time
Instantaneous response to external events. A real time simulation, like a driving simulator, follows the pace of events in reality.
The concept of seeing actions on a computer screen as through the activity were happening at a natural pace. As in "real-time proofing".
Describes a system that guarantees an immediate response time.
Occurring immediately. When events happen in a consistent rate with events in the outside world. LiveRender(tm) engine renders at a consistent rate with events, to retain an interactive, immerse experience. LiveRender engine is reacting to your input and presenting you with new updated images immediately.
happening live and on-the-fly. Three-D action games such as Doom, feature real-time rendering, while games such as Myst contain pre-rendered graphics.
A conversation which takes place at the time the members of the conversation are communicating. Telephone conversations are "real-time" while exchanging e-mail correspondence is not. LeAnn chatted (by typing messages back-and-forth) with her friend George over the Internet using IRC where they could discuss their class notes together in real-time.
Computations or data communications that occur instantaneously or nearly so with the execution of a command or transaction.
The term "real-time" means to incur immediately. For credit card processing, this means that the validity of a customer's credit card, as well as their available credit limit can be checked immediately before processing is accepted. This is extremely important for card-present and Internet transactions, in which it is difficult and costly to get back in touch with the customer.
Live: happening now. When you play a piano you are playing in real-time. When you program a computer to play a piano part you are programming in real-time but, as a whole, the piece of music has been created out of. real-time. When the computer plays the program it is playing non-real-time music.
Immediate, as an event is occurring
The transmission of data in the real-world present according to our experience of time. Real-time communications are usually synchronous, like telephone conversations, video-conferencing, MUDs, and "live" satellite broadcasts. The Internet can be used for real-time communications and information delivery, and there are already successful implementations of real-time video and audio on the Net.
Real-time is a method of narratology, most commonly used in film or television, where events being represented or portrayed exactly as it occurs. The exact time of the story action is would be equal to the time it takes to view that action.
Real time is a term used to describe a motion picture, television or radio program, or computer game wherein the events depicted take place entirely within the span of time that lasts from the beginning of the depiction to the end, and at the same rate.
