5. Live Signal Handling (v2.0)
Besides playing videos and graphics, just:live/just:play also allows you to manage live incoming signals like studio signals or satellite feeds and send it to the output. This can be done:
- using the more traditional way by controlling a mixer/router or
- by configuring the play out video device to do so.
Using the video hardware, there are 2 different ways to do so, the DS Keyer and the non DSK method. Both methods can be used in SD and HD but not in UHD. The following shows the differences between the two methods.
Because the live signal is passed through using the AJA device, there is NO delay added to the live signal.

Because the live signal is sent to our engine which buffers the incoming signal, a minimum of 12 frames delay is added to the live signal. This means that the signal which has been received minimum 12 frames ago is visible at the output. The buffer depends on the video buffer defined for the just:out engine under the Layers & Engines tab of just:connect and can be between 12 frames (Video buffer OFF) and a bit more than 3 seconds (Video buffer 3 Seconds). |
