An asynchronous communication service or application does not require a constant bit rate. [2] Examples are file transfer, email and the World Wide Web. An example of the opposite, a synchronous communication service, is realtime streaming media, for example IP telephony, IPTV and video conferencing.
Some examples of hard real-time systems: A car engine control system is a hard real-time system because a delayed signal may cause engine failure or damage. Medical systems such as heart pacemakers. Even though a pacemaker's task is simple, because of the potential risk to human life, medical systems like these are typically required to undergo ...
Real-time communication systems are generally understood as one of two types: Hard Real-Time (HRT) and Soft Real-Time (SRT). [2] The difference between a hard and soft real-time communication system is the consequences of incorrect operation.
An optical communication system is any form of communications system that uses light as the transmission medium. Equipment consists of a transmitter, which encodes a message into an optical signal, a communication channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.
Real-time camera, for controlling views in a 3D virtual environment; Real-time communication, for interactive communication; Real-time operating system, for running real-time software; Real-time protection, protection enabled constantly, rather than by, say, a virus scan; Real-time text, transmitted as it is being typed or produced
Real-time computer graphics systems differ from traditional (i.e., non-real-time) rendering systems in that non-real-time graphics typically rely on ray tracing. In this process, millions or billions of rays are traced from the camera to the world for detailed rendering—this expensive operation can take hours or days to render a single frame.
Multi-communicating has evolved with the rapid development of information and communications technology (ICT), where behavior within digital media applications like Slack and Skype thrive. With the emergence of portable devices like laptops, people can use multi-communication tools during meetings and non-meeting activities. [3]
Real-time text programs date at least to the 1970s, with the talk program on the DEC PDP-11, which remains in use on Unix systems. Beam Messenger, a mobile app offering real-time text messaging, was released in 2014. [3] Certain real-time text applications have a feature that allows the real-time text to be "turned off", for temporary purposes.
