What (who) is transit delay - definition

TIME INTERVAL BETWEEN AN INPUT AND A RESPONSE

Low latency; Lag time; Delayed data feed; Low-latency; Transit delay; Network Lag; One-way latency; Motion To Photon Latency

Delay (audio effect)

AUDIO EFFECT REMINISCENT OF AN ECHO

Tape delay (audio effect); Echo machine; Analog delay; Doubling echo; Slapback echo; Delay (electric guitar); Delay pedal; Delay unit; Delay Pedal; Straight delay; Delay effect; Tape echo; Delay (audio); Ecco-Fonic; Delay (recording); Delay (music); Delay-line (audio); Delay-line (music); Delay-line (recording); Delay line (audio); Delay line (music); Delay line (recording); Tape-echo; Tape Echo; Multitap delay; Haas delay; Slapback

Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio.

Latency (engineering)

Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.

Shapiro time delay

TIME DELAY CAUSED BY SPACE-TIME DISTORTION NEAR MASSIVE OBJECTS

Shapiro effect; Time delay of light; Gravitational time delay; Shapiro delay

The Shapiro time delay effect, or gravitational time delay effect, is one of the four classic solar-system tests of general relativity. Radar signals passing near a massive object take slightly longer to travel to a target and longer to return than they would if the mass of the object were not present.

Latency (engineering)

Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.

Latency is physically a consequence of the limited velocity at which any physical interaction can propagate. The magnitude of this velocity is always less than or equal to the speed of light. Therefore, every physical system with any physical separation (distance) between cause and effect will experience some sort of latency, regardless of the nature of the stimulation at which it has been exposed to.

The precise definition of latency depends on the system being observed or the nature of the simulation. In communications, the lower limit of latency is determined by the medium being used to transfer information. In reliable two-way communication systems, latency limits the maximum rate that information can be transmitted, as there is often a limit on the amount of information that is "in-flight" at any given moment. Perceptible latency has a strong effect on user satisfaction and usability in the field of human–machine interaction.
