Live internet streaming requires a form of source media (e.g.a video camera, an audio interface, screen capture software), an encoder to digitize the content, a media publisher, and a content delivery network to distribute and deliver the content.The user can invite any current viewer to join the broadcast by tapping an icon on the bottom right.
As of 2017, "streaming" generally refers to the situation where a user watches digital video content or listens to digital audio content on a computer screen and speakers (ranging from a smartphone, through a desktop computer to a large-screen home entertainment system) over the Internet.
"Streaming" was applied in the early 1990s as a better description for video on demand and later live video on IP networks first by Starlight Networks for video streaming and Real Networks for audio streaming; at the time such video was usually referred to as "store and forward video", which was misleading nomenclature.
Live streaming is the delivery of Internet content in real-time, as events happen, much as live television broadcasts its contents over the airwaves via a television signal.
Rather, the live video is available for all your followers to see in real time.
Viewers can send hearts and comment on the video, as well.
Instagram is testing it with a small percentage of users and said it will introduce it globally over the coming months.
