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 as below.
Blu-ray Player
Encoder
1G Ethernet Switch
Power Adapter

PC Decoder
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.
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.
11 / 19
169 168 110 30 0
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.
12 / 19
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.

Notes: (1) 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. (2) 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. (3) 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. (4) 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. (5) No need to care about settings of Video LAN port of the Controller Box, as they are managed by Controller automatically (Default). (6) When the Network Switch does not support PoE, the Encoder, Decoder and Controller Box should be powered by DC power adapter.
