S3 filters out echo region to be treated by the echo board of the processor from the echo message
Echo message, and image data is transferred to by controlling terminal according to the echo message and is echoed.
In this step, needs can be filtered out from the echo message by the echo board 202 of the processor 20
The echo message in the echo region of processing.For example, No. 1 processor can filter out the list that number is 1-4 from the echo message
The echo message of member screen, No. 2 processors can filter out the echo message for the unit screen that number is 5-8 from the echo message,
And so on.Then, the echo board 202 of each processor 20 can pass acquired image data according to the echo message
It is defeated to be echoed to controlling terminal 10.
For the accuracy for guaranteeing echo message, acquired image data are being transferred to by control according to the echo message
After terminal 10 is echoed, relevant parameter can be returned to Control card 201 by echo board 202, by Control card 201
The parameter is verified.When check results are correct, the parameter can be returned to control eventually by the Control card 201
End 10；When check results are incorrect, error result can be returned to controlling terminal 10 by the Control card 201.The ginseng
Number may include echo area size coordinate (top, left, width, height), i.e., (upper, left, wide, high), network address character
String explanation.
In one embodiment, the echo method can comprise the further steps of:
By showing that board 203 can filter out the processor 20 display area to be treated from the display information
Display information；
The 20 acquired image data of processor are transferred to the display screen of combination 30 according to the display information
It is shown.
Above-mentioned echo method has the advantage that
(1) image is handled by the processor of multiple cascade connections, improves the efficiency of echo；
(2) each processor respectively verifies the echo result of the image respectively handled, and it is accurate to can be improved echo
Degree, and verification is high-efficient, can be handled in time when finding mistake.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
