11.5.1 Sync Mode
The Sync Mode check box disables the ARC feature when input and output formats are the
same. This gives the lowest latency.
11.5.2 Signaling Detected
Signaling Detected shows the status of any aspect ratio signaling detected at the input. If
Status shows “None”, no valid signaling is detected.
11.5.3 Sidebar Keying & Output Crop
The Sidebar Keying & Output Crop functionality provides post ARC cropping of the output
picture and allows a second video picture to be keyed into the cropped area. When output
cropping is enabled, the actual size of the output picture does not change, just how much of
the active picture remains visible. The portion that is “cropped” is either default black (in
Output Crop mode) or is replaced by a secondary video picture (in Sidebar Key mode) – the
“cropped” portion still forms part of the output picture.
