Introduction
HE4000 Encoding System
2.1 Rear Panel Connections
All HE4000 external connections are located on the rear panel, as shown in the following
illustration.
2.1.1 Video Ports
The HE4000 provides connections for both analog and SD and HD digital video.
2.1.2 Analog Video In
Analog Video In is a female BNC connector with 75Ω impedance, accepting a NTSC or PAL
composite analog video input that is 1.0 Vp-p nominal level. The analog composite video input
must be compliant with SMPTE 170M NTC, ITU-R BT.470, or PAL-I/B/D. The connector shell is
connected to signal ground.
Connect the video input cable to the Comp In connector on the rear panel.
2.1.3 Digital Video In
SD SDI Video In is a female BNC connector with 75Ω impedance, accepting SD SDI video that is
1.0 Vp-p nominal level. The SD SDI video must be compliant with SMPTE-259M. The connector
shell is connected to signal ground.
HD SDI Video In is a female BNC connector with 75Ω impedance, accepting HD SDI video that is
1.0 Vp-p nominal level. The HD SDI video must be compliant with SMPTE-292M. The connector
shell is connected to signal ground.
HD Loop-Through is a female BNC connector with 75Ω impedance, accepting HD SDI that is 1.0
Vp-p nominal level. The HD SDI must be compliant with SMPTE-292M. The connector shell is
connected to signal ground.
