MJPEG Substream Operation Introduction

6.1 MJPEG Substream Preview/Configuration via Web Page

The product supports playing MJPEG Substream on computer through the corresponding software such as VLC media player, simultaneously you can access the Web page to configure the MJPEG Substream.

Follow the steps below to preview and configure the MJPEG Substream.

Step 1: Connect the Encoder, Decoder and PC to the same Switch, then connect an HDMI source device and power supply. The connection diagram is shown below.

A connection diagram illustrates connecting a Blu-ray Player to the Encoder via HDMI, the Encoder to a 1G Ethernet Switch via LAN (PoE), and the Switch to a PC. The Decoder is also connected to the Switch via LAN (PoE) and to a TV via HDMI OUT.

Step 2: Install a bonjour protocol checking tool (such as zeroconfService Browser) on PC to find the IP address of the Encoder/Decoder. Take zeroconfServiceBrowser as an example. After opening the software, you can select "Workgroup Manager" in Services of Browser, select the Host name in Service-Instances, and find the IP address in the Address item in of Instance-Info.

A screenshot shows the zeroconfServiceBrowser interface, displaying services and service instances with IP addresses.

Note:
(1) The window in the lower left corner displays the Host names of all devices in the current network.
(2) The window in the lower right corner displays the Host name, IP address and Port number of the device.
(3) The Host name of Encoder starts with AST-ENC; the Host name of Decoder starts with AST-DEC.

Step 3: Set the PC's IP address to the same network segment with IP address of the Encoder/Decoder found in step 2.

Step 4: According to the IP address of the Encoder/Decoder found through the bonjour protocol checking tool, input "http://IP:PORT/?action=stream" into the web browser on PC. The MJPEG Substream will be displayed with the default resolution, as shown in the figure below.

A screenshot shows a test pattern displayed in a web browser.

Step 5: Change the resolution of the obtained Encoder/Decoder IP address in the following format.

http://IP:PORT/?action=stream&w=x&h=x&fps=x&bw=x&as=x&mq=x

WIDTH: [Optional] image width. In pixels. 'x' means no change. Default is 640.
HEIGHT: [Optional] image height. In pixels. 'x' means no change. Default is 360.
FRAMERATE: [Optional] frame rate of sub-stream. Unit: fps (frame per second). 'x' means no change. Default is 30.
BW: [Optional] maximum bandwidth of sub-stream traffic. Unit: Kbps (Kbits per second). 'x' means no change. Default is 8000 (8Mbps).
AS: [Optional] aspect ratio configuration. 'x' means no change. Default is 0.
• 0: extend to what "WIDTH" and "HEIGHT" configured
• 1: [A1 only] keep original aspect ratio and place in the center of output (letterboxing or pillarboxing)
MINQ: [Optional] minimum image quality number. Range: 10, 20, ..., 90, 100, higher setting means better image quality. 'x' means no change. Default value is 10. Limit driver auto bandwidth control's minimum quality number. If quality lower then MINQ value, the driver will drop frame by returning 0 size file.

After changing, input the new Encoder/Decoder IP address into the web browser on PC, the MJPEG Substream will be displayed with the desired resolution, as shown in the figure below.

A screenshot shows a test pattern displayed in a web browser with modified URL parameters.

6.2 VLC Media Player Instruction

Firstly, perform the step 1~3 as described in Chapter 6.1, then open the VLC media player on PC. Please see the following icon.

An icon for VLC media player is shown.

Click "Media > Open Network Stream"

A screenshot shows the VLC media player menu with "Open Network Stream" highlighted.

After clicking the "Open Network Stream" option, the following page will appear.

A screenshot shows the "Open Media" dialog in VLC media player.

Enter the MJPEG Substream network URL, then click "Play" button.

A screenshot shows the VLC media player playing a test pattern.

Choose "Tools>Codec information", a pop-up window will display and show you Stream information, as shown in the figure below.

A screenshot shows the "Current Media Information" window in VLC, detailing codec information.

Choose "Tools>Codec information>Statistics" to check current Bitrate. Please see the following picture.

A screenshot shows the "Current Media Information" window in VLC, detailing statistics including bitrate.

Note: The Bitrate is floating up and down when you check it. This is a normal phenomenon.

Switch Model

A network Switch used to set up the system should support below features:

Type of layer 3/managed network Switch.
Gigabit bandwidth.
8KB jumbo frame capability.
IGMP snooping.

The following Switch models are highly recommended.

Manufacturer	Model Number

4K over IP System Control

This product can be controlled by Controller Box or third-party controller. For details of 4K over IP system control, please refer to the user manual of "Video over IP Controller".

Application Example

A system diagram illustrates a network setup with multiple Encoders (ENC) connected to a 1G Ethernet Switch, which is also connected to a Controller Box and a PC. Decoders (DEC) are connected to the Switch and then to TVs. The diagram also shows a video wall setup with 4 Decoders.

The terms HDMI and HDMI High-Definition Multimedia interface, and the HDMI Logo are trademarks or registered trademarks of HDMI Licensing LLC in the United States and other countries.

Notes

The Controller has two LAN ports, one is Video LAN and the other one is Control LAN. The purpose of designing Controller with two LAN ports is to isolate audio/video (AV) network from control network. So to make AV network as an independent network which can not be accessed from control network directly, it's for bringing network security and avoiding AV network traffic flowing into the network in which the controls and managements are for the IP system. The strongly recommended system setup is connecting Video LAN and Encoders/Decoders in a network Switch, connecting Control LAN and PC in another network Switch. The controls from Control LAN can be achieved by Web GUI/Telnet or SSH login/API commands, all these controls can be bridged by the Controller and applied onto Video LAN. The two LANs are isolated. For simple usage, you can only connect all Encoders/Decoders and Video LAN and PC RJ-45 port into a single network, and let the Control LAN port not-connected (floating), as Video LAN also supports Web GUI/Telnet or SSH login/API commands controls, this seems “convenient” for general use scenarios, but this is only suggested for system in which there is no network isolation requirement or network traffic non-sensitive. Only Control LAN connected while Video LAN floating, this is not allowed.
For the default IP mode of Control LAN port of the Controller Box is DHCP, the PC also needs to be set to "Obtain an IP address automatically" mode, and an optional DHCP server (e.g. network router) is recommended in the system.
If there is no DHCP server in the system, 192.168.6.100 will be used as the IP address of Control LAN port. You need to set the IP address of the PC to be in the same network segment. For example, set PC's IP address as 192.168.6.88.
You can access the Web GUI by inputting URL "http://controller.local" or the Control LAN port IP address 192.168.6.100 (in case of no optional router) on your computer's browser.
No need to care about settings of Video LAN port of the Controller Box, as they are managed by Controller automatically (Default).
When the Network Switch does not support PoE, the Encoder, Decoder and Controller Box should be powered by DC power adapter.
