Tutorial: Live Switching, Streaming, and Recording with the Epiphan Pearl

Jan Ozer demonstrates how even the most non-technical user can pull off a live-switched stream with the Epiphan Pearl streaming appliance.

Choosing Streaming and Encoding Options

For each channel, you can specify streaming options. I’m streaming to Ustream (Figure 7, below), using encoding options chosen in the Encoding screen shown in Figure 8 (below Figure 7).

Recording Your Program

You can also record the program feed that you’re streaming to the internet, with options set in the Recording screen (Figure 9, below).

Note that Pearl has 1 TB of on-board storage, so you’ll have plenty of room for recordings. Live streaming starts as soon as you choose the channel and input your server credentials. That’s why you need the pre-show slide.

You control recording via the Start and Stop controls shown at the top of Figure 9, or using the recording control on the touchscreen itself.

Once you’re live, you can switch layouts using the web interface, or using the touchscreen control on the front panel.

That’s a quick look at the Epiphan Pearl. You get four simultaneous HD streams at 30fps, recording and live-switching with an interface that even the most non-technical user can operate.
