Introduction
The H.264 HDMI Video Encoder streams 1080p video from an HDMI video source to a media streaming server
(Wowza, Xtreme Codes, Nginx, etc) or online live broadcast platform (YouTube Live, FaceBook Live, IBM Cloud
Video (Ustream), etc) over IP in real time. It encodes video using H.264 compression and AAC/MP3 audio.
Features:
Accepts 1080p HD video at 60 frames per second and produces IP streams that can be sent on a standard
Ethernet cable.
Encode the same HDMI video source in two different formats and resolutions - unicast and multicast.
Supports RTMP, RTSP, UDP, HTTP, HLS, FLV and ONVIF protocols
Compatible with most Internet live broadcast platforms, such as YouTube Live, Facebook Live, Twitter Live,
Twitch, and IBM Upstream.
Broadcast to SmartTVs using a media streaming sever, such as Wowza, Xtreme Codes, Nginx, etc.
Easy-to-use HTTP-based web interface.
oModify network and video quality settings such as IP address, bit rate, and fps.
Add text and logos to the video stream.
Supports 100Base-T Ethernet connection.
Linux inside.
Ideal solution for many applications, including:
oDigital signage
oIPTV/SmartTV
oHotel TV systems
oLive broadcast
oClassrooms - teaching online
oIP video surveillance
oVideo conference

Settings:
Upon Initial Login to the User Interface through your browser, you will be provided with a Status Display providing the following
information:
Input Status : shows the type of input signals that are attached
Running Time: Indicates how long the Encoder has been connected to the Input Source
CPU Usage: Typically 25% (if this value is more than 85%, there may be an excess drain on the resources of the source)
Input Size: 1920x1080p@60Hz (Default configuration for the source)
Collected Video Frames: 65116 (Indicates how many frames of video have been encoded from the source)
Lost Video Frames: Indicates how many frames have dropped by the encoder
Audio Sample Rate: 48000
Click on the "Network Settings" tab to view the current network settings and MAC address for the Encoder.
Be sure to enter the proper DNS server and Gateway address. Otherwise the Encoder will not be able to connect with the
internet and stream video to your desired destination.

To set the destination, configure the video settings for one or more Mainstream addresses:
Field Description
FPS Max. is 60fps, but when input is 1080i, fps will be halved (for deinterlacing)
GOP Group of pictures (recommend using the same value as the FPS)
BITRATE (kbit) Value depends on the video quality needed (suggestions:
1080p@3500kbs, 720p@2800kbs, SD@1500kbs)
Encoded size Encoded Output Resolution.
H.264 Level: Profile-baseline / main / high Profile
High Profile is recommended
Bitrate control: Vbr (Variable Bitrate) or Cbr (Constant bitrate)
MIN_QP Minimum Quantization Parameter (Typically between 1-35) The larger the value,
the more stable the bandwidth will be, but video quality will decrease.
Recommend using the default value (5))
MAX_QP Maximum allowable is 50, default is 42
TS URL /0.ts Select to Enable or Disable

HLS URL /0.m3u8 Select to Enable or Disable
FLV URL /0.flv Select to Enable or Disable
RTSP URL /0 Select to Enable or Disable
Multicast IP 238.0.0.1 Select to Enable or Disable
Multicast port Port to use for multicasting video/audio (1-65535)
RTMP PUBLISH URL Address of the real time media player to broadcast encoded video to.
RTMP Settings:
Wowza- rtmp://serverIP:port/Application/stream name
i.e. - rtmp://192.168.1.50P:1935/live/oupree
If Wowza requires Source Authentication, the source is username oupree , password is 123456, so the address will be:
rtmp://oupree:123456@192.168.1.50P:1935/live/oupree
Xtream Codes- on its panel, write address as rtmp://127.0.0.1:8001/live/stream name
OSD- to display the transparent logo, set the background color as 0xF1F1F1 or R-177 G-204 B-233,
See examples on pages 7 and 8.
Audio Encoding Settings:
Generally, leave these set at the default (as shown below), but if you feel comfortable changing the settings, set as needed.
System Settings:
In this window you can change the password if desired.
