  2. Jitter - Wikipedia

    en.wikipedia.org/wiki/Jitter

    Jitter period is the interval between two times of maximum effect (or minimum effect) of a signal characteristic that varies regularly with time. Jitter frequency, the more commonly quoted figure, is its inverse. ITU-T G.810 classifies deviation lower frequencies below 10 Hz as wander and higher frequencies at or above 10 Hz as jitter. [2]

  3. Media Delivery Index - Wikipedia

    en.wikipedia.org/wiki/Media_Delivery_Index

    The Media Delivery Index (MDI) is a set of measures that can be used to monitor both the quality of a delivered video stream as well as to show system margin for IPTV systems by providing an accurate measurement of jitter and delay at network level (Internet Protocol, IP), which are the main causes for quality loss. Identifying and quantizing ...

  4. Packet loss - Wikipedia

    en.wikipedia.org/wiki/Packet_loss

    The amount of packet loss that is acceptable depends on the type of data being sent. For example, for voice over IP traffic, one commentator reckoned that "[m]issing one or two packets every now and then will not affect the quality of the conversation. Losses between 5% and 10% of the total packet stream will affect the quality significantly."

  5. Wow and flutter measurement - Wikipedia

    en.wikipedia.org/wiki/Wow_and_flutter_measurement

    The circuits used to control these frequencies do permit a very small amount of flutter (usually termed jitter), but the level is far below that which the human ear can discern. The linear sound track on VCR video recorders has much higher wow and flutter than the VHS-HiFi high fidelity track which is contained within the video signal.

  6. Packet delay variation - Wikipedia

    en.wikipedia.org/wiki/Packet_delay_variation

    Instantaneous packet delay variation is the difference between successive packets—here RFC 3393 does specify the selection criteria—and this is usually what is loosely termed "jitter", although jitter is also sometimes the term used for the variance of the packet delay. As an example, say packets are transmitted every 20 ms.

  7. Network performance - Wikipedia

    en.wikipedia.org/wiki/Network_performance

    Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude , or phase of periodic signals.

    Technically, anything over 20 years old can be coined “vintage.”But when you truly think of items worth this title, your brain doesn’t go to Beanie Babies.

  9. Unit interval (data transmission) - Wikipedia

    en.wikipedia.org/wiki/Unit_interval_(data...

    Jitter is often measured as a fraction of UI. For example, jitter of 0.01 UI is jitter that moves a signal edge by 1% of the UI duration. The widespread use of UI in jitter measurements comes from the need to apply the same requirements or results to cases of different symbol rates. This can be d
