A couple of simple steps will guide through necessary settings and operations. VGADVI Recorder Pro HD RM enables you to simultaneously record up to two HD video sources, two SD sources up to three audio sources. Stream the result live to your audience and share it on the web for 24×7 access. In this example we explain how to connect and configure the VGADVI Recorder Pro HD RM model in order to capture, record and broadcast two HD sources, e.g. video feed from a camcorder and a DVI display.
- VGADVI Recorder Pro HD RM.
- A camcorder with HD video output.
- A laptop with network access for streaming a DVI output and configuring VGADVI Recorder Pro HD RM settings.
- DVI and RJ-45 Ethernet cables.
10/100/1000Base-T Ethernet network access is also required.
Step 1. Connections and settings
Hook up the HD video output of the camcorder and the laptop’s DVI output to the VGADVI Recorder Pro HD RM’s DVI inputs. Use an RJ-45 Ethernet cable to connect the VGADVI Recorder Pro’s Ethernet port to an Ethernet network. Connect the power cable to the VGADVI Recorder Pro. Turn on VGADVI Recorder Pro, laptop and camcorder. As soon as VGADVI Recorder Pro is connected to network, it is assigned an IP address. Now you should use the Network Discovery Utility to connect to the Web admin interface. This interface allows you to manage recording and make all necessary settings.
- Download the Epiphan Network Discovery Utility to your laptop from the manufacturer’s website and start this program.
- Now select Search to find the device on the network. Its name and IP address are displayed in the Name and Address fields.
- Start your web browser and browse to the IP address of VGADVI Recorder Pro. Enter the user name “admin“. No password is required.
You have accessed the Web admin interface where it is possible to create video channels and configure the required settings as explained below.
- Both HD sources are displayed in the Sources section of the Web admin interface as D2P84074.vga and D2P84014.vga.
- Click Add channel in the Channels section to create a multi-source channel named D2P84014_vga. Select the first source – D2P84014.vga.
- Now add the second source to this channel – D2P84074.vga.
- In the Video sources muxing pane of this channel you must create a channel’s layout, i.e. specify how videos from both sources are positioned on the screen relative to each other.
Step 2. Make the recording
- Make sure that both camcorders are working properly. Select the Files Archive section of the multi-source channel. Specify the file type, time and size limits. Now click Start. The VGADVI Recorder Pro is now recording synchronously both video feeds from the camcorders.
- While the recording is being performed you can preview the current recording. Click the Channel Status section of th multi-source channel. Now click the “Live broadcast” URL.
- You will see the preview of the recording in your browser.
- When the recording must be finished, click Stop.
Step 3. Uploading a lecture on server automatically
You can configure the system to automatically upload a recording to an upload server. VGADVI Recorder Pro HD RM can upload each video file after it stops recording it or upload all recorded video files with various periodicities.
In the Web admin interface find the Automatic File Upload section. Define the server type and select Enable Automatic File Upload. Now set Remote Path to the path on the upload server. Then select Apply.
Step 4. Broadcasting a lecture
It is possible to broadcast a recording to remote viewers as soon as you have provided them an IP address of the broadcast and the credentials. To support larger number of viewers, especially when multiple clients are outside of the LAN, you may need to subscribe to Content Delivery Network (CDN). This service redistributes the stream for multiple viewers. Make sure all viewers know the broadcast’s IP address and credentials. They should start a web browser or a media player and use this address to immediately access the broadcast.
