For example, central processing unit 12 can be controlled handover module SW with image processing channel C H 1Couple computer terminal port P 1, cause image processing channel C H 1Received controlled computer B 1Be sent to computer terminal port P 1First signal of video signal, and image processing channel C H 1Can carry out image processing to first signal of video signal.Certainly, central processing unit 12 also can be controlled handover module SW switching image processing channel C H 1Couple computer terminal port P 2, cause image processing channel C H 1Received controlled computer B 2Be sent to computer terminal port P 2Second signal of video signal, and image processing channel C H 1Can carry out image processing to second signal of video signal.
In the present invention, from Q image processing channel C H 1～CH QIn selected a certain image processing passage can be divided into following two kinds to the operator scheme of sampling from the signal of video signal of computer terminal port:
Under physical channel pattern (first pattern), image processing channel C H 1Sample frequency that can a per second N image frame is sampled to the signal of video signal from same computer terminal port, and will be converted to a continuous per second N static image frame from the signal of video signal of same computer terminal port by analog-to-digital converting module 301.For example, as shown in Figure 3, when central processing unit 12 is controlled handover module SW with computer terminal port P 1Be coupled to image processing channel C H 1The time, be in the image processing channel C H under first pattern 1Will be with the sample frequency of a per second N image frame to computer terminal port P 1Be received from controlled computer B 1The first signal of video signal SG 1Sample, and pass through analog-to-digital converting module 301 with the first signal of video signal SG 1Be converted to a continuous per second N static image frame.In fact, N can be 30, that is is in the image processing channel C H under first pattern 1To the first signal of video signal SG 1Sample frequency can be 30 image frames of per second, but not as limit.
See also Fig. 4 A and Fig. 4 B, under tunnel pattern (second pattern), image processing channel C H 2Sample frequency that can a per second N1 image frame is to sampling from the signal of video signal of a computer terminal port, obtaining first sampled data, and is converted into per second N1 static image frame by analog-to-digital converting module 301, and image processing channel C H 2Also with the sample frequency of a per second N2 image frame another signal of video signal from another computer terminal port is sampled, to obtain second sampled data, and be converted into per second N2 static image frame by analog-to-digital converting module 301, wherein N1 adds that N2 is equal to or less than N.That is to say, be in central processing unit 12 under second pattern and can control handover module SW in two different computer terminal ports (computer terminal port P for example 2And P 3) between alternately switch.For example, shown in Fig. 4 A, under the very first time, when central processing unit 12 is controlled handover module SW with image processing channel C H 2Couple computer terminal port P 2The time, image processing channel C H 2Sample frequency that can a per second N1 image frame is to computer terminal port P 2Be received from controlled computer B 2The second signal of video signal SG 2Sample, obtaining first sampled data, and be converted into per second N1 static image frame by analog-to-digital converting module 301; Shown in Fig. 4 B, under second time, 12 control handover module SW switch image processing channel C H when central processing unit 2Couple computer terminal port P 3The time, image processing channel C H 2Sample frequency that can a per second N2 image frame is to computer terminal port P 3Be received from controlled computer B 3The 3rd signal of video signal SG 3Sample, obtaining second sampled data, and be converted into per second N2 static image frame by analog-to-digital converting module 301.Under the 3rd time, again can be shown in Fig. 4 A, central processing unit 12 control handover module SW are with image processing channel C H 2Couple computer terminal port P 2Under the 4th time, again can be shown in Fig. 4 B, central processing unit 12 control handover module SW switch image processing channel C H 2Couple computer terminal port P 3, all the other can the rest may be inferred, do not give unnecessary details separately.
In fact, because in the sampling process under first pattern (as shown in Figure 3), unless the user assigns the instruction of switching computer terminal port, otherwise the action that handover module SW can't switch, but in the sampling process of second pattern (shown in Fig. 4 A and Fig. 4 B), even the user does not assign the instruction of switching computer terminal port, handover module SW still can be subjected to the control of central processing unit 12, in two different computer terminal ports (computer terminal port P for example 1And P 2) between alternately switch to realize the effect of two virtual image treatment channel.Therefore, under identical a period of time (a for example second), image processing channel C H 2The number of the image frame that samples under first pattern (N) will be greater than (or equaling) image processing channel C H 2The number summation (N1+N2) of the image frame that under second pattern, samples.For example, suppose that N equals 30, and N1 and N2 be equal to 10, that is image processing channel C H 2The sample frequency that adopts under first pattern is 30 image frames of per second, and image processing channel C H 2Sample frequency that can 10 image frames of per second under second pattern is to computer terminal port P 2The second signal of video signal SG 2Sample, and with the sample frequency of 10 image frames of per second to computer terminal port P 3The 3rd signal of video signal SG 3Sample.
