 RUNNING THE ENCODER

 

 

This section gives step-by-step instructions on using the Z3-SBE264-10-RPS to stream 1080p or 1080i video 
to VLC media player running on your PC. In addition to the Z3-SBE264-10-RPS, an HD source with SDI output 
and a PC are required. (HDMI Output can also be used. See Section 7.13 for details.)

 

 

*Note:

 

Actual version numbers for your Z3 product may differ from those pictured in this document.

 

 

7.1

 

 Set up the HD Source

 

 

(1)

 

Select a video source with SDI output.

 

-Alternately, a video source with HDMI output and an HDMI->SDI converter can be used.  In this 

case, an HDMI source with non-HDCP output must be used (HDMI source used at Z3: the Brite-
View BV-5005HD).

 

 

 

-Power on the video source.

 

 

 

-Connect the source to a monitor.

 

 

 

-Select content you would like to stream.

 

 

If you see playback on the monitor, you’ve confirmed the source works.  If you are using an HDMI 
source, you should move the HDMI cable from the monitor to the HDMI->SDI converter.
