Dennis: The PAR will output three types of video signals as you know: composite; Y/C; and component Y,R-Y,B-Y. The betacam SP decks require sync to be fed externally no matter what video signal you feed them if the sync switch is set for external. Some beta decks always need this sync to be external and have no sync switch. The easiest way to do this is hook up the composite video output from the PAR to the sync input of the betacam deck. If you also need composite video you can loop it through the composite video in and then to the sync input. Most of the time you will be using a component or Y/C signal but, again, in all cases you need sync and can get it from the composite video signal. The PAR manual references "genlock loop thru" This is NOT a sync or black burst signal _from_ the PAR. The genlock loop through is used to establish a common timing reference when using the PAR/TBC4 and any other video sources in connection with editing equipment. Again, use the video composite output for reference sync when the PAR is the source.
