The technique aims to improve the display of a fast-moving video image — such as a computer game, a DVD, or the signal from a TV card. Most video cards manufactured since about 1998 and most media players support hardware overlay. [1]
A depiction of 5 display refresh cycles with what may be shown during a micro stuttering case. Each colored section represents one of the GPU's frame buffer and each color change represents a frame buffer swap.
Regardless of bandwidth requirements, any type of a service which requires consistently low latency or jitter-free transmission can be affected by bufferbloat. Such services include digital voice calls (VOIP), online gaming, video chat, and other interactive applications such as radio streaming, video on demand, and remote login.
Video overlay is any technique used to display a video window on a computer display while bypassing the chain of CPU to graphics card to computer monitor.This is done in order to speed up the video display, and it is commonly used, for example, by TV tuner cards and early 3D graphics accelerator cards.
Comparison of a slow down video without interframe interpolation (left) and with motion interpolation (right) Motion interpolation or motion-compensated frame interpolation (MCFI) is a form of video processing in which intermediate film, video or animation frames are generated between existing ones by means of interpolation, in an attempt to make animation more fluid, to compensate for display ...
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.
Every meter of distance adds around 3 ms delay due to the limitation of the speed of sound. Jamulus is client-server based; [12] each client transmits its own compressed audio to a server on the internet. The server mixes the (decompressed) audio stream for each user separately and re-transmits the individual compressed mix to each client.
Adaptive streaming overview Adaptive streaming in action. Adaptive bitrate streaming is a technique used in streaming multimedia over computer networks.. While in the past most video or audio streaming technologies utilized streaming protocols such as RTP with RTSP, today's adaptive streaming technologies are based almost exclusively on HTTP, [1] and are designed to work efficiently over large ...
