2. Preparation for Live streaming
2.1. Video input source
Need to have a device to input for e8.
The e8 encoder supports only 8K 2sample interleave (2SI) format. (4K 2SI x4 inputs are not
supported.)
Fig: Conceptual diagram of 8K 2SI input from 12G SDI
2.2. Stream receiving equipment
Need to prepare the server, decoder and monitor to receive live streaming as you needed.
2.3. Control devices for e8
Need to prepare ’monitor’, ’monitor cable (VGA) ’, ’keyboard (USB)’, and ’mouse (USB)’.
(These devices are not needed when the e8 GUI is controlled by the system other than localhost.)
2.4. Launching e8 / Shutdown e8
Launching e8: Press the power on/off button to launch e8.
