Answer / saeid
We need 10 bits to show 1024 colors in a binary system,
therefore 10 bits are required for each pixel to be
addressed.
We need 1300*1000*10 bits to send a complete content of a
screen.

Answer / amit vyas
Saied Answer looks good, Total bits can be reduced further.
We need not have 1300*1000*10 bits. Since for most of the
1300*1000 pixels, the 10 bits will be same and within 0 to
1023 range. So we can send pixels numbers in groups
according to their colors.
Ex: say all blue are represented by 1111
and blue pixels are 1000,1010,10000
Than we can send this group as
1111:1000,1010,10000$
Similarly we can append info. for all other colors this way.
Total bits that will be sent will be
1300*1000 + 1024*10+1024*2(special bits, we don't need space
for comma, its shows here only for illustration)
So we reduced the total bits to a smalller number
