Short definition
Live streaming is the real-time transmission of video and audio content over the internet to a digital audience. At events, it reaches remote viewers alongside the in-person audience.
Detailed explanation
Professional live streaming covers the full signal chain — from camera capture through the control room to encoding and delivery to streaming platforms. Common protocols include RTMP for platforms such as YouTube or LinkedIn Live, and SRT for low-latency, reliable transmission over unstable networks.
Encoding is handled by hardware encoders (e.g., Teradek, LiveU) or software solutions (OBS, vMix). Hardware encoders offer greater stability and bonding capabilities that combine multiple internet connections — critical for outdoor events without a fixed line. Stream quality depends on upload bandwidth, codec, and bitrate: 1080p50 typically needs 8–15 Mbps, while 4K requires 25–50 Mbps. Redundant connectivity — fiber as primary, LTE/5G bonding as backup — is standard in professional productions.
Relevance in this field
Live streaming has grown from an add-on service into a central part of many event concepts. Companies expect to reach international audiences simultaneously without travel costs, which requires service providers to combine AV expertise with IT networking and content delivery skills.
Practical example
A trade show streams its keynote stage live to its own event platform. A control-room setup with a video switcher, two cameras, and on-screen graphics provides the source feed. A hardware encoder with LTE bonding keeps the stream running even with unstable venue infrastructure, while a local recording runs in parallel as backup.
