1. INTRODUCTION1. INTRODUCTION
• This paper studies the design challenges for unmanned
vehicular video streaming.
• The major challenge in this area is providing fast image
processing with low latency, under limited space, limited
weight, limited power and limited link bandwidth
constrains. This paper offers the fundamental design
choices and rule of thumb.
• And situational awareness with UXV platforms imposes
some requirements on the video handling sub-system.

In order to decrease power
consumption ,we adopted
96 small Micro Processors,
as shown in Figure , each
one runs at 96MHz, drain
1mW, total 96mW; however,
the amount of computation
that can be done is almost
equivalent to
96×96=9216MHz single
high speed CPU, which
would otherwise drain
96×96×96= 884736mW
power, by theory!

B. Main Challenge for the Vehicle
• In this chapter, we have done a number of
tests near an intersection where a fatal
accident occurred - a high school girl was
killed by a speeding car, slipped through the
traffic light.• The following figures show a car-accident-cyclists,
percentage of victims killed in speed crashes by
crash type and percentage of pedestrians killed in
intersection crashes by age.

In general, we have something to do to save life. For that , we have done a number of tests to make a difference between the progressive scan and the interlaced scan, the horizontal interlaced scan and the vertical interlaced scan.
The following figures show the difference among horizontal scan, vertical scan and horizontal-vertical scan,
