3D TV
Bandwidth is at a premium when multiple monitoring aspects are being utilized, the simplified method shown allows spatial orientation using one camera feed.
(There is an error on the picture, the method referred to as cccv is "ccd ", as what I was referring to hasn't been used for some time, and the current reference isn't for release) 
Addendum
Using a sampler, the bandwidth can be farther narrowed, especially good for such as the Light Antenna . The method of only showing changes can allow motion variations, or new objects moving in the path of the point of reference, once locked onto a distant object, and the sampling techniques available now, it would allow detection of incoming bodies, or simply identifying new bodies around/near those bodies. The electronics are available for video samplers, and using a variation of the one used for security work where only the change is set to make an alarm go off, once the shot is scanned in. The method of using a sampler for the basic picture, allows fine tuning it to sample the primary scan and place an identical scan in the following retrace, this can be modified to only do a part scan retrace with the sampler to allow minimal false signal, undetectable to the finished product, and allow at least a 50% reduction of needed bandwidth.(As well as only show the object that is moving if needed)
I have placed a passive amplifier on the site that should be usable to enhance the signal much like a LNA, as well as it can be used to link electronic sections together, as a coupler ckt to defeat static exchange problems, without distortion. Using it as a LNA , and the fact it's passive, certain noise is eliminated, and the lack of filtering networks reduces power to weight problems associated with multiple LNA stages.
LNA = Low Noise Amplifier
In this case , the noise is inserted by the base amplifier and that needs to be filtered, but the Passive Amplifier needs no filters, nor does it insert noise when used a coupler circuit.
Addendum 2
In free space , the enormity of distance prevents reliable depth perception , as there is no nearby objects to compare your target with , this obviously would present dangers if negotiating movement of material/s , the above simplistic approach to solving this by remote cameras , is simply a backup method, as electronics can fail, such as radar, or worse , it becomes unstable, and the backup computer doesn't catch it, due to some glitch or another, this is where such a simple device would save the day, as it can be configured with a triangulation measuring device, such as mundane Earth type binoculars have. Safety redundancy is necessary in space, the more you have, the more likely you will complete your mission, as most such devices are too expensive , this inexpensive setup would seem a reliable method to overcome this discrepancy.
