MPEG2/4 HD-SDI to QAM and IP Encoder User Manual
Chapter 1 Introduction
1.1 Product Overview
This MPEG4 AVC/H.264 HD IP & ASI Encoder is a professional HD audio & video encoding and
multiplexing device. It has 1x ASI–IN, 8x HDMI (=Model 8220) or 8x HD-SDI (= Model 8210)
video input interfaces, supporting MPEG-4 h.264 video encoding and MPEG 1 Layer 2 audio
encoding. This device can simultaneously encode 8 channel of HD audio & video; moreover,
it has an IP output port and support 1 MPTS and 8 SPTS on IP out and 2x parallel ASI Out. In
conclusion, its high integrated and cost effective design makes the device widely used in
varieties of digital distribution systems such as cable TV digital head-end, satellite digital TV
broadcasting, Digital Signage etc..
1.2 Key Features
4 HDMI or HD-SDI video inputs with 4 SPTS and 1 MPTS output

Gigabit Ethernet IP output over UDP and RTP/RTSP, 4 x SPTS + 1 MPTS
2 parallel ASI output as copy of the MPTS
Null PKT Filter function
PID Remapping
PCR accurate adjusting
PSI/SI editing Control via web management, and
Management via WEB-IF or Front Panel, easy updating by web-interface
We assume that the user is familiar with IP settings and already knows his own system to connect the unit to.
If you use the Output Streaming feature: We recommend using 2 separate Switches! At least a 100BaseT for
the Management NMS RJ45 port and a second one with Gigabit Ethernet 10/100/1000BaseT with at least
Layer 2+ with IGMP V2 features. Otherwise you might flood your IP-Streaming network with unnecessary
Data, which might overload connected IPTV STB's because they almost have only 100BaseT capacity (Never
ones use 1GbE ports) but too many inputs into a STB can result in side effects. If you need to select a Switch,
we recommend ARUBA HP Procurve 2530 24G or 48G which are cost effective, easy to configure, can be
trunked and supporting IGMP V2. For this model it's better to check the Firmware version because sometimes
the newest one has IGMP problems.
If the switch needs routing functions, the bigger brother of this series might be the right choice.
Because to not accidently put DATA and NMS port in the same sub-network the data – port setting does not
allow this by default. Usually the DATA GbE Port needs an IP address- otherwise the Switch or the receivers
(i.e. IPTV STB's) cannot locate the source of the streams.
