II. THE DESIGN OF REMOTE CONTROL SOFTWARE
Remote control software consists of two parts. One part
is the server program, and the other part is the client program
[1]. Firstly, the client program needs to be installed on the
main control computer, and the server program also needs to
If the screen image is directly transmitted in bitmap
format, it may cause control delay which is relatively large.
In order to improve the transmissions' efficiency, we
compress the data before it was transmitted to increase the
control of data transmission. In addition, we also can use the
screen image’s transmission delay’s file format to improve
the rate, it reduces the control delay by compressing the
screen image which were directly transmitted into data
stream. Taking account of the maximum UDP protocol’s
packet length is 64KB, and the compressed screen image
data exceed 64KB, since the compression ratio can’t too be
large, we use TCP protocol to transfer the screens’ image
data.
