Below in conjunction with Figure of description, each embodiment of the present invention is described in detail.
Embodiment mono-:
As shown in Figure 2, for the embodiment of the present invention one a kind of controls the flow chart of the method that vision signal shows, described method comprises:
Step 101: receive at least one road vision signal.
Wherein, in described each road vision signal, carried input path mark.
Described vision signal is one or more in simulation high-definition video signal, digital high-definition signal.
In step 101, receive multi-channel video signal by channel transmission equipment, because the vision signal of channel transmission device transmission is high-definition signal, can also be digital signal and high-definition signal can be analog signal, therefore, in the time receiving simulation high-definition signal, simulation high-definition video signal is carried out to analog-to-digital conversion, obtain digital high-definition video signal.
Step 102: after receiving at least one road vision signal, whether each road vision signal that judgement receives has data head frame and have data tail frame.
Particularly, in step 102, in the time determining that the vision signal receiving has data head frame and has data tail frame, execution step 103; In the time determining that the vision signal receiving does not have data head frame and/or do not have data tail frame, determine that this vision signal is incomplete vision signal, and returning to the equipment that sends this vision signal the message that resends this vision signal, the equipment that indication sends this vision signal resends this vision signal.
Like this, avoid at a large amount of video signal data frames, in transmitting procedure, being dropped because the network carrying causes Frame, made the incomplete problem of vision signal, guarantee that the vision signal that display device receives is complete vision signal, improved display efficiency.
Step 103: the quantity of the vision signal that statistics receives.
In step 103, the mode of the quantity of the vision signal that statistics receives includes but not limited to following mode:
A kind of mode is: the quantity of the vision signal with identical input path mark is added up, obtain the vision signal quantitative value of described input path mark;
Another kind of mode is: the total quantity of the vision signal receiving is added up, obtain total vision signal quantitative value.
Step 104: the quantity of the quantity of described statistics and setting is compared, in the time that the comparative result quantity that is described statistics is greater than the quantity of setting, execution step 105; In the time that the comparative result quantity that is described statistics is not more than the quantity of setting, execution step 106.
Particularly, in step 104, the set-up mode of the quantity of described setting includes but not limited to following two modes:

More preferably, in the time that the vision signal receiving need to be transmitted through the fiber to other equipment, the bearing capacity of the quantity of described statistics and optical fiber is compared, in the time that the comparative result quantity that is described statistics is greater than the quantity of setting, execution step 105; In the time that the comparative result quantity that is described statistics is not more than the quantity of setting, execution step 106.
Step 105: determine the input path mark of each the road vision signal receiving, the vision signal with identical input path mark is compressed to processing, obtain compressing vision signal after treatment.
In step 105, judge in time video signal data amount waiting for transmission larger, adopt compress technique that vision signal is compressed, improve the speed of transfer of data.
It should be noted that, in the time vision signal being compressed to processing, can select wherein at least one road vision signal, carry out compressing in Frame for each road vision signal of selecting, can also compress by Shi Jiangji road video signal integration, be not specifically limited here.
Step 106: according to the input path mark of carrying in the described at least one road vision signal receiving, described vision signal is sorted, the vision signal after being sorted.
More preferably, after the vision signal after being sorted,
Step 107: according to the corresponding relation that predefined input path identifies and at least one shows paths between mark, determine the mark that shows paths corresponding to each road vision signal of having carried input path mark.
In step 107, described input path mark and at least one corresponding relation showing paths between identifying can arrange before signal transmission carrying out, it can also be the provisional configuration that needs according to display device, that is to say, set up in advance in this locality the corresponding relation that each input path identifies and each shows paths between mark, the i.e. corresponding multiple marks that show paths of input path mark, and a corresponding input path mark of the mark that shows paths.
The described definite mode identifying that shows paths corresponding to each road vision signal of having carried input path mark includes but not limited to following mode:
Select show paths one or more in mark of corresponding multiple of input path mark, the mark that shows paths of selecting is determined to the mark that shows paths corresponding to each road vision signal of having carried input path mark.
For example: receive 4 tunnel vision signals, the each road vision signal respectively input path of correspondence is designated 1,2,3 and 4, corresponding shows paths as A, B, C and D, set up respectively 1 and A, 1 and B, 1 and C and 1 and D between mapping relations, therefore, input path is designated 1 video signal transmission to display device before, can select to show paths into A, B or C, D, can also be A, B and C etc., so just can guarantee by the A that shows paths, B, C and D show video signal transmission to display device.
Step 108: the vision signal receiving is transferred to display device according to corresponding the showing paths of mark that show paths of determining, controls display device and show.
By the scheme of the embodiment of the present invention one, in the time receiving at least one road vision signal of having carried input path mark, according to predefined input path mark and at least one corresponding relation showing paths between mark, determine the mark that shows paths corresponding to each road vision signal of having carried input path mark, and the vision signal receiving is transferred to display device according to corresponding the showing paths of mark that show paths of determining, controlling display device shows, avoid like this vision signal of inputting in prior art in the time that display device shows, because display mode is more single, fixing, the low problem of display efficiency of the vision signal causing, utilize predefined input path mark and at least one corresponding relation showing paths between mark, realize the object that Liao Ge road vision signal shows flexibly in multiple display devices.
