It depends a bit on what sort of interfaces there are between the items of equipment. If they are coaxial for video and screened balanced pairs for audio, then those standards certainly fit. If Ethernet or similar is used, then EN 55022 and EN 55024 may be more appropriate. I think you would have difficulty in trying to apply EN 55013 and EN 55020; too much interpretation would be required. -- OOO - Own Opinions Only.
