Live Streaming Workflow
High level view of video streaming workflow for live content.
High level view of video streaming workflow for live content.
Measure of time between request for media by player to time media is rendered for playback (e.g. first frame rendered for user).
Measure of total time for network request (e.g. for a media object) to travel over the network and for response to travel back.
Quick UDP Internet Connections (QUIC) is a UDP-based transport layer network protocol. HTTP/3 uses QUIC to achieve performance enhancements (e.g. simpler handshakes, multiplexing) such as lower latency media streaming.
Measure of underlying technical aspects or characteristics of media streaming (ITU.T P.10 item 6.212), including: performance, availability. Poor QoS can impact PVQ and/or QoE. In contrast to QoE, QoS is an expression of the system’s various technical characteristics including: network performance (e.g. packet loss, e.g. network jitter, e.g. bitrate, e.g. . . . Read more
Quality of Experience is a measure of overall delight or annoyance of viewer’s media streaming experience (ITU.T P.10 item 6.209). Many factors can impact QoE, including: poor PVQ, poor QoS, poor application performance. In contrast to QoS, QoE is an expression of the end-viewer’s overall sentiment regarding the usage of . . .

Measure of visual quality of video content as perceived by viewers. Poor PVQ can impact QoE. Poor QoS can impact PVQ. The perceived video quality can be evaluated by computers based on mathematical models in laboratory or production settings (see Objective Video Quality) or based on human observation in informal . . .

The average time it takes to resolve an issue. In media streaming context, the issue can impact streaming QoS, PQ or QoE.
The average time it takes to detect an issue. In media streaming context, the issue can impact streaming QoS, PQ or QoE.
HTTP Live Streaming is an Apple standard for ABR media streaming using fMP4 or MPEG-TS containers and H.264 or H.265 video codecs.
