1. From the web interface, click Stream Setup. The Steam Setup page opens displaying configuration settings for
DVI and S-Video channels.
2. No need to change anything right now. Review some of the default settings. The four most useful settings to
know about are codec, frame size, frame rate and bitrate.
a. The codec is set to H.264 by default.
b. The frame size should reflect the resolution provided by your source. You can set it to something different
by typing in the fields or selecting an option from the different sizes shown. Scaling the image (making it
larger, smaller, or different aspect ratio) takes some processing power, so it’s always best to leave this at
the value detected by the system unless you know it is wrong or know you need to scale the size.
c. The frame rate limit is set to 30. This means the system won’t spend extra computing time to attempt to
receive more than 30 frames per second. For perspective, NTSC TV signals use 24 frames per second and
most hand-drawn animations show only 12 unique frames per second.
d. The bitrate is automatically calculated based on the resolution of the input signal. Raising this value uses
more system processing power and more bandwidth.
You may now optionally add audio to your channel:
3. Scroll to the bottom of the Stream Setup page and ensure the Enable audio checkbox is enabled (enabled by
default) for the audio source to which you connected your 3.5 mm audio cable.
4. Leave the default PCM 22KHz format and audio bitrate.
5. Click Apply.
Your stream setup is complete. Since most of the steps are pre-configured; you are up and running with a stream very
quickly. You can share the live broadcast link with your viewers on your local area network (LAN). Depending on your
internet connection and upstream bandwidth, you may need to adjust the video bitrate down before sharing over the
internet.
Step 6: Record the stream
The device is set up and streaming. This may be all you need, but if you like, you can also record the stream.
To record the stream:
1. From the web interface, click the red Start button at the top of the menu; the text at the top of the screen
changes to indicate the recording is starting, then indicates the length of time since the recording started.
2. Click the black Stop button; the recorder stops.
3. To view the result, click Recorded Files; the recorded files page loads and a file list appears that displays your
newly recorded stream snippet.
4. Click the file name to download and view your recording.
