Chapter 1 Product Description
SD-00 loop through
The Player/Recorder application has a “E-to-E (LoopThru) mode” selection on the
Control menu. This mode applies when the channel is under local AppCenter control
as well as when it is under remote control, for all protocols.
This “E-to-E (LoopThru) mode” feature allows you to monitor the video that is being
recorded. The video is routed back essentially untouched. Any AES audio or LTC that
is on the input video is still there on the loop through. The SD-00 K2 Media Client
and the loop through videos must be locked to a video reference for the loop through
feature to work properly. This “E-to-E (LoopThru) mode” feature should not be
confused with true E to E, such as that on the SDA-00 K2 Media Client. True E to E
is not supported on the SD-00 K2 Media Client.
When “E-to-E (LoopThru) mode” is not selected, the channel behaves as follows:
• “PB” is displayed on the channel pane, next to the Timecode Source indicator.
• When no clip is loaded, black plays out.
• When a record operation stops, Recorder becomes Player and the clip remains in
the Player. The clip’s last frame plays out.
When “E-to-E (LoopThru) mode” is selected, the channel behaves as follows:
• “EE” is displayed on the channel pane, next to the Timecode Source indicator.
• When no clip is loaded, the signal that is currently present at the channel input
plays out.
• When a record operation stops, Recorder stays Recorder and the clip remains in the
Recorder. The signal that is currently present at the channel input plays out.
HD-00 loopback
HD-00 models provide a loopback feature with which you can monitor the video that
is being recorded. The video is routed back essentially untouched. Any ancillary data
or embedded audio that is on the input video is still there on the loopback. The HD-00
K2 Media Client and the loopback videos must be locked to a video reference for the
loopback feature to work properly.
Loopback should not be confused with an E to E feature. E to E is not supported on
the HD-00 K2 Media Client.
NOTE: The loopback path is for monitoring purposes only.
