In contrasting the various solutions it is important to focus on the key performance factors. Density describes how closely a connector can be placed on a panel in an array. More density means more channels per rack unit. Robustness is important to ensure that  installations operate flawlessly, both as they are installed and then throughout their extended lifecycles. It is important to consider bandwidth as new technologies such as 3G-SDI and 3D are deployed and while deploying a new interface one should consider extended capabilities for future generation technologies. In the end it all comes down to the user experience. If the system designers, integrators and installers cannot adopt the new technology then it will not be an effective solution. With that in mind, the HD-BNC™ utilizes the same bayonet style mating as the BNC.
