1 Overview
1.1 Product introduction
This new generation of MPEG-4/H.264 SD/HD Encoder supports HDMI, HD/SD
SDI, YPbPr, CVBS, SPDIF input and ASI and IP output. With improved algorithm
and compression efficiency, it presents major improvements in picture quality,
offering crisp and vibrant video at extremely low bit-rates. It helps deliver more
SD/HD video and audio channels in the available bandwidth, enabling the
launch of additional SD/HD service in an existing digital video or an IPTV
network.
1.2 Function & Features
Compatible with MPEG-4/H.264-AVC standard
MPEG-1 LayerⅡaudio encoding
SD video input format: NTSC/PAL
HD video input format: SMPTE-296/SMPTE-274
Support HDMI, SD/HD SDI, YPbPr and CVBS input
Digital SPDIF audio input
Support multiplexing of MPEG-4 video and audio compressed data stream
with DVB packets
SI related table editing
Support SD or HD TS stream output with the corresponding definition of
input signal
Two identical ASI outputs
IP output compliant with UDP/RTP protocol (optional)
Convenient and simple NMS for long-range management of the equipment

2 Operating instruction
Please make sure that all input/output cables are connected well. The
parameters can be configured by the operation of buttons through the guide of
menu displayed on LCD screen.
2.1 Start up
Start up the encoder, after about 8 seconds, the LCD displays initial state:
After start up, the encoder starts to encode automatically, LCD displays as
follows:
It includes the type and IP address of this equipment.
2.2 Hierarchical menu
Operation menu is a multilevel menu. The first level is initial interface. Each
menu item could have its own submenu. In the same way, each submenu item
can have its own submenu too. Due to the limitation of word count displayed, it
only can display one menu item at one time. Each menu item can display two
lines of content: the first line is the name of menu item; the forepart of second
line is the present value of adjustable parameter. The parameter can be
modified in the process of encoding.

2. 3 Menu flow rules
1. Due to the limitation of word count displayed, it is impossible to display all
menu items in the same level. Menu items in the same level can be switched
through the two buttons ‘↑↓’.
2. The parameter only can be modified in the end level menu. Press button ‘OK’
to entry the lower level menu when it chooses a non-end level menu.
3. There is more than one way to enter the lower level menu from the higher
level menu.
4. Enter the end level menu, and modify the parameter and press ‘OK’ to save it.
If it has no use for modifying the parameter value, press ‘MENU’ to return the
next higher level menu and keep the former parameter value, or press ‘OK’ to
confirm the former one.
5. During the process of encoding, LCD will return the initial interface
automatically if any button operation stays on a menu item over 5 minutes.
Notice: to modify any parameter and save it, you need press ‘OK’ to enter
the editing status firstly, and then press ‘↑→↓←’ to select other options or
input the parameter. Lastly, press ‘OK’ to save the new parameter.
