20HS-600 Video LayersThe HS-600 is a Standard Definition Digital Video Switcher and as well as mixing video and audio sources it hasadditional functions such as Picture In Picture (PIP), CG LUMA KEY and LOGO.Before attempting to use the HS-600 PIP, CG LUMA KEY and LOGO functions it may help to first understand theorder of the video layers at the HS-600 Program (PGM) outputs.The Background video layer is the normal video layer when mixing and switching with the HS-600. It occupies thewhole screen area of the Program output. This layer can be hidden or part hidden by the PIP, LUMA KEY andLOGO layers in front of it.The PIP 2 layer does not occupy the whole screen and is shown in front of the Background video layer whenenabled. In some setups the PIP 2 image can be hidden behind the PIP 1 image. This is not a fault. Change theposition or size of the PIP 1 or PIP 2 image if required.The PIP 1 layer does not occupy the whole screen and is shown in front of the Background video and PIP 2 layerswhen enabled. In some setups the PIP 1 image can hide the PIP 2 image. Change the position or size of the PIP 1or PIP 2 image if required.The CG LUMA KEY layer can occupy the whole screen. If set up incorrectly this layer can stop the video layersbehind it from being seen properly. Re-adjust your CG LUMA KEY settings or switch off the CG LUMA KEYfunction on the HS-600 to restore the video behind it.The LOGO layer does not occupy the whole screen and all other layers are visible through it. A logo if positionedincorrectly can partially hide an important part of the video, PIP or CG LUMA KEY layers. Typically logos or stationID bugs are placed in a corner of the screen.NB: Logos need to be prepared and positioned in advance of the live production starting as they only appear onthe program output.Most broadcast networks have guidelines and advice on the use of video, images, music, logos and on screen textso it is best to check beforehand when planning a production.
