Twitter lets you broadcast live videos on your Twitter page using Periscope Producer with an existing Twitter account. First connect your Twitter account to your Periscope Producer account and grant Periscope sharing permissions. Pearl-2 works with Periscope to push the stream to Twitter by providing the encoded video stream. Using RTMP (real-time messaging protocol), your live broadcast is then pushed from the Pearl system to Periscope Producer and in turn to your Twitter page.
