How to capture lectures, stream them and upload them to LMSs (Learning Management Systems) or Servers
Capturing and sharing lectures and other educational materials is a standard distance learning strategy. Lecture recording for later re-use is also an effective means of providing low-cost, high quality training.
This tutorial shows you how to configure Epiphan’s Lecture Recorder x2™ to record and stream a video and audio feed as well as upload this material to a server. A couple of simple steps guide you through necessary settings and operations. You will be able to record a lecture itself together with the presentation provided by a lecturer from two video output sources and an audio source, broadcast it live to the interested audience and share it on the web for 24×7 access. In this example we use the Lecture Recorder x2 device from Epiphan Systems.
- A digital camcorder on a tripod to capture the presenter’s likeness
- The lecturer’s laptop with presentation
- A laptop or computer on the same network as the Lecture Recorder x2
- A microphone to capture the presenter’s voice
- An Epiphan Lecture Recorder x2
- DVI and S-video cables.
- 10/100Base-T Ethernet network access
Step 1. Connections and settings
- Connect the camcorder’s video output to Lecture Recorder x2’s S-video input (using an adapter, if needed). All input ports are on the same side as the LEDs.
- Connect the presenter’s laptop DVI output to the Lecture Recorder x2’s DVI input port.
- Connect the microphone to Lecture Recorder x2’s Audio input port.
- To provide power to the Lecture Recorder x2, plug the provided PoE adapter into a 10/100Base-T Ethernet network using an Ethernet cable.
- If needed, turn on all video sources
- Connect a laptop to the same network as the Lecture Recorder x2. (This can be the presenter’s laptop or another laptop – it is needed only for initial configuration of the Lecture Recorder.)
- From the laptop, download and install Epiphan’s network discovery tool from the Lecture Recorder x2 download page.
- Start the network discovery utility
- Click Search to find the Lecture Recorder x2 on the network. Its name and IP address are displayed in the Name and Address fields.
- Click Web config… to start the Lecture Recorder x2 web admin interface; a browser window opens. Enter the user name “admin“. No password is required.
- Click Stream Setup. In the DVI Channel section configure the DVI channel settings.
- In the Video Channel section configure the SD channel settings. You can also specify the required picture-in-picture layout.
- To configure audio settings, click Audio.
Step 2. Recording the lecture
- Make sure the camera and microphone are working properly and the presentation is shown using the laptop. (If needed, use the DVI and pass through ports on the Lecture Recorder x2 for local audio and video.)
- In the Web admin interface click the Recorded Files button. Click Change to specify the file type, time and size limits.
- Click the Start button to start recording; Lecture Recorder x2 begins synchronously recording video and audio feeds as the lecture occurs.
- You can preview the video while the lecture is being recorded. Click the Live View button in the Web admin Interface. You will see the preview of the lecture as it is being recorded.
- When the lecture is finished, click Stop.
Step 3. Uploading a lecture on server automatically
You can configure the system to automatically upload a lecture to an upload server. Lecture Recorder x2 can upload each video file after it stops recording it or upload all recorded video files at configured intervals.
- 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. Streaming a lecture
It is possible to stream a lecture to remote viewers (even while recording). Simply provide the Live View link to your viewers. To support more than a couple of viewers, especially when multiple clients are outside of the LAN, you may need to use multicast or subscribe to Content Delivery Network (CDN). Multicast systems and CDNs redistribute the stream for multiple viewers.
