Product Overview
The h.264/h.265 compatible Encoder is a hardware device used for high-definition video signal (up to 1080p60
HD resolution) encoding and network transmission, using the latest and high-efficient HD digital video
compression technology h.264/H.265, with the characteristics of reliable, high-definition, low bitrate and low
latency. Connect the HDMI/SDI/VGA high-definition video signal to start the encoding process, after the
compression processing by the DSP chip, the output of the standard TS network stream can be started.
The launch of these devices fills the gap in the industry, which is a direct replacement for the traditional
capture card for software coding method, using hard-coded chipsets, the system is more stable, and the
picture quality is more perfect. They can be used in a wide variety of demands for high-definition video and
high-resolution / high frame rate re-assembling for IP based network transmission. Its powerful scalability
makes it easier to respond to the needs of different industries and can be used as live video encoder. Industrial
controlled, precision design, small size, easy installation, the power is less than 5W, which is energy-saving
and more stable.
This general manual applies to the following models:
All SoC DSP based boxed Encoders SDE- HDE - and SHDE.
Where S stands for SDI, H = HDMI, SH for both in a box, D =Digital, E= Encoder, 2nd D = Decoder Version like
HDD-275.

Basics - Unicasts:
RTSP over HTTP
The key of RTSP over HTTP is to allow RTSP packets to communicate via HTTP port.
We know that the standard port of RTSP is 554, but due to various security policy configurations such as firewalls,
there may be restrictions when the client accesses port 554, which prevents the normal transmission of RTSP packets.
But the HTTP port (port 80) is generally open, so there is the idea of letting RTSP packets pass through port 80, namely
RTSP over HTTP.
The details of RTSP over HTTP are as follows:
First, the client opens two socket connect to the rtsp server HTTP ports. We call these two sockets "data socket" and
"command socket".
Step 1. The client sends an HTTP GET command through the "data socket" to request an RTSP connection.
Step 2. The server responds to the HTTP GET command through the "data socket" and responds with success/failure.
Step 3. The client creates a "command socket" and sends an HTTP POST command through the "command socket" to
establish an RTSP session.
At this point, the auxiliary function of HTTP is completed, and the server does not return the client's HTTP POST
command. Next is the standard process of RTSP on the HTTP port, but it needs to be completed through two sockets.
The "command socket" is only responsible for sending, and the "data socket" is only responsible for receiving.
Step 4. The client sends RTSP commands (BASE64 encoding) through the "command socket".
Step 5. The server responds to the RTSP command (in plain text) through the "data socket".
Step 6. Repeat Step4-Step5 until the client sends the RTSP PLAY command and the server responds to the RTSP PLAY
command.
Step 7. The server transmits audio and video data to the client through the "data socket" After the data exchange is
complete...
Step 8. The client sends the RTSP TEARDOWN command (BASE64 encoding and) through the "command socket"
Step 9. The server responds to the RTSP TEARDOWN command (in plain text) through the "data socket".
Step 10. Close the two sockets.
Secure Reliable Transport
SRT (Secure Reliable Transport) is an open-source Internet transmission protocol based on UDT protocol. Haivision and
Wowza have cooperated to establish SRT alliance to manage and support open-source applications of SRT protocol.
This organization is committed to promoting the interoperability of video streaming solutions and realizing low latency
network video transmission.
SRT is improved from UDT (UDP based Data Transfer) protocol. SRT protocol retains most of the core concepts and
mechanisms of UDT protocol, and introduces some improved and enhanced functions, including flow control for real-
time audio and video, enhanced congestion control, modification of control data, and improvement of encryption
mechanism.
SRT protocol features:
Three features: safety, reliability and low latency.
In terms of security, SRT supports AES encryption to ensure end-to-end video transmission security.
In terms of reliability, SRT ensures the stability of transmission through forward correction technology (FEC).
In terms of low latency, SRT is based on UDP protocol, which solves the problem of high transmission latency of TCP

protocol.
SRT solves the complex transmission timing problem, and can support real-time transmission of high-throughput files
and high-definition videos.
Advantages of the SRT protocol:
Reliability: It is suitable for any network environment and can efficiently handle network packet loss, jitter, bandwidth
fluctuation and other disturbances;
Low latency: Due to the UDP transmission mode and ARQ packet loss recovery mechanism, the transmission delay
level based on the public network can generally be controlled within 1s;
High quality: SRT's transmission and error correction mechanism can maximize the use of available bandwidth and
eliminate network errors and interference, so it can transmit higher bit rate video streams in the same network
environment, and cooperate with H Efficient encoding formats such as 264 and HEVC can ensure high video quality
under poor network conditions;
High bandwidth utilization: The multi rate adaptive distribution technology, which is different from ABR, requires
additional bandwidth for redundant rate. SRT monitors the network link status in real time and can adjust the rate in
real time (NAE, network adaptive coding). In addition, ARQ's packet loss recovery mechanism also greatly saves
bandwidth and reduces network congestion compared with TCP's packet loss recovery mechanism;
Security: SRT uses AES-128 or 256 encryption to protect content security;
Free and open source: SRT is completely free and open source.
Shortcomings of SRT:
SRT is based on bidirectional UDP point-to-point connection, which is suitable for high-quality, low latency and reliable
transmission of point-to-point, but not suitable for content distribution to mass users.

WEB server –Access settings
Step 1: Reset & initialization
Connect the power supply to turn on the encoder and use a pin to press RST on the encoder for min. 10 seconds (better 15), it
will be restarted and initialized. The default Route IP of the WEB-IF is 192.168.1.168 (This default Address may vary depending
on model) after initialization and can be recognized from the sticker at the bottom.
HINT if you lose your IP address, there is a ‘RESET’-Button hole at the front. Press until 1 LED goes off (>10seconds).
Step 2: Change the administrator’s computer IP
Set the administrator’s computer IP as: 192.168.0.* or 192.168.1.*to avoid IP conflicting with the units own IP address IP
192.168.0.*: (use an IP setting “*” in the number range between 2-254 except .1.168) Remark: .0 is often the network router, .1
often the Gateway of the used router.
Step 3: Login the menu with the web browser:
Enter 192.168.1.168 in your Browser window.
Default user Name: admin
Default password: admin
(remark: here IP address changed before)
You are entering the STATUS window:
A remark upfront:
If you APPLY, you need to confirm this:
This DOES NOT MEAN to restart your encoder but rather your decoder because you changed encoding settings and
the decoder -like VLC- must adapt itself to the new values.

Some hints for SDI-Encoder types:
Because the SDI signal has some other values to consider than HDMI Inputs,
If you face problems with the SDI-Inputs detecting and showing only 1080p as Input regardless of the real Input is a 1080i
(Interlaced) Video source (i.e. a Camera), please disable the SMPTE-Setting in the System-Submenu ‘Advanced’ section:

Configure a planned scheduled restart:
Upgrade the Firmware and initialize a reboot:
The settings as well as the Firmware can be back-upped and re-uploaded.
The config-settings-file is a Linux based text file named box.ini.Do not modify that by a windows editor
except you will use notepad++ (freeware –please google...). Windows has different CR/LF notation than
Linux based TXT-files.
Finally i.e. after firmware update has been uploaded, the unit can be remotely reset to factory defaults or
rebooted.

A Pop-Up Message will inform you to confirm the changes you made:
Main stream encoding settings:
We assume, that the user already well knows the relevant terms and abbreviations for Video-Encoding and their technical
background.
Chose your codec. (new in 2019: MJPEG support)
Main - basic video encoding settings:
⚫Enc type: h.264 & h.265 (is optional dep. on model) or MJPEG (new in 2019)
Note: h.264 version can only use h.264 codec, h.265 model can do both
⚫Profile: baseline profile / main profile / high profile (note: h.265 version select main profile)
⚫Frame rate: 5-60 (If the input resolution is 720i/50,1080i50, the frame rate will be set to 25)
⚫Bitrate mode: VBR / CBR variable or constant while CBR is the better choice
⚫Group of pictures: 5-200, shows picture quality, default setting is almost sufficient
⚫Bitrate: 16-16000 kbit/s or 32-32000 kbit/s dep. on Model (Network bandwidth setting)
Note: You can modify the above parameters without rebooting the encoder
Some encoders like 4K version supporting GOP settings in 4 different modes.
The GOP should be an integer factor / divider from the selected FPS/Hz value. So if you set your fps to 30, it should be 5, 6, 15
or 30. Set to 25 would lead you to 5 or 25…:
Selecting your output screen size/resolution:
Note: The encoder is not intent to use for upscaling purpose i.e. 720 -> 1080. It always depends on the Input resolution and size.
Downscaling is possible but you should calculate also the SAR settings than:
