Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method and device of transmission video signal.
Background technology
At present, along with the development of technology, it is universal rapidly that large-screen splicing shows that wall has obtained.Large-screen splicing shows that wall consists of several displays, and each display can receive the vision signal of a signal source transmission and show corresponding video image.
Fig. 1 realizes the system architecture schematic diagram that large-screen splicing shows wall in prior art.As shown in Figure 1, system comprises S1 ~ S4 totally 4 signal sources, M1 ~ M4 totally 4 matrix switchers, and shows walls by A ~ L large-screen splicing that totally 12 displays form.
In Fig. 1,4 input channels of matrix switcher M1 are connected with signal source S1 ~ S4 respectively, and 5 output channels of matrix switcher M1 are connected with 5 input channels of matrix switcher M2 respectively.Matrix switcher M2 has 8 output channels, and wherein 4 output channels are connected with 4 input channels of matrix switcher M3 respectively, and other 4 output channels are connected with 4 input channels of matrix switcher M4 respectively.Matrix switcher M3 and matrix switcher M4 all have 6 output channels, are connected respectively with the input channel of these 12 displays of A ~ L.
Wherein, for a matrix switcher, from the vision signal of input channel input of this matrix switcher, can export from any one or several output channel of this matrix switcher, but an output channel of this matrix switcher can only be exported from the vision signal of an input channel input of this matrix switcher.Also, an input channel of a matrix switcher can be to a plurality of output channels that should matrix switcher, but an output channel of a matrix switcher can only be to a input channel that should matrix switcher.
And, at large-screen splicing, show in wall system, for a matrix switcher, by other matrix switchers that are connected with the input channel of this matrix switcher, be called upper level matrix switch, other matrix switchers by being connected with the output channel of this matrix switcher, are called subordinate's matrix switcher.For example, in the system shown in Fig. 1, the upper level matrix switch of matrix switcher M2 is that matrix switcher M1， subordinate matrix switcher is matrix switcher M3 and matrix switcher M4.
Because signal source and large-screen splicing show between the display in wall, be that several matrix switchers by cascade are connected, therefore, in the time of the video signal transmission of signal source output will being arrived to the display of appointment, just need to determine the path of transmission video signal.
For example, in the system shown in Fig. 1, if the vision signal of signal source S1 output is shown on display A and display B, just need to determine respectively that signal source S1 is to the path of display A and display B, and the path transmission vision signal based on definite.
Yet, in prior art, be by the artificial path of determining transmission video signal.Continue along using example, when the vision signal of signal source S1 output will be shown on display A and display B, need artificial definite signal source S1 to divide to be clipped to need between display A and display B which input channel and the output channel by which matrix switcher, this not only requires user very familiar to the annexation of the matrix switcher of each cascade in system, and the efficiency in definite path is also very low, thereby cause the efficiency of transmission video signal lower.

Embodiment
Owing to needing artificial definite signal source of designated signal that sends to the path of designated display in prior art, the efficiency of therefore transmitting designated signal is lower.The embodiment of the present invention is in order to improve the efficiency of transmission video signal, in the time will designated signal being transferred in designated display, the signal source of indication transmission designated signal is transmitted this designated signal, and from designated display, upwards search step by step the equipment that input channel receives this designated signal, until find, the equipment that foundation finds is to the path of designated display, designated signal is transferred in designated display, to realize the path of automatically determining transmission designated signal, and without artificial definite path, improved the efficiency of transmission video signal.
Below in conjunction with Figure of description, the embodiment of the present invention is described in detail.
The process of the transmission video signal that Fig. 2 provides for the embodiment of the present invention, specifically comprises the following steps:
S201: in the time of designated signal being transferred in designated display, the signal source of indication transmission designated signal is transmitted this designated signal.
In embodiments of the present invention, in the time will designated signal being transferred in designated display, transmitting device first indicates the signal source that sends this designated signal to start to transmit this designated signal.
The system shown in Fig. 1 of still take describes as example, in the time the vision signal of signal source S1 output will being shown on display A, the vision signal that this signal source S1 sends is designated signal, and display A is designated display, and first indicator signal source S1 starts to send designated signal.Now, input channel on each matrix switcher in supposing the system and output channel are not set up out and can be made designated signal be transferred to the path on display A, therefore,, even if signal source S1 starts to send designated signal, display A can not receive this designated signal.
S202: according to the annexation between each equipment of preserving in advance, determine the intermediate equipment being connected with the input channel of designated display, select this intermediate equipment to connect an output channel of this designated display.
In embodiments of the present invention, transmitting device has been preserved the annexation between each equipment in system in advance, concrete, for certain equipment in system, transmitting device has been preserved the output channel of other equipment that the input channel of this equipment connects in advance, and the input channel of other equipment of connecting of the output channel of this equipment.
Continue along using example, designated display is display A, and the input channel of display A is to AI1, and the intermediate equipment being connected with the input channel AI1 of display A is matrix switcher M3.Because the input channel of display A only has one (input channel AI1), so the output channel that matrix switcher M3 connects display A also only has one, is M3O1, so the output channel M3O1 of selection matrix switch M3.
S203: judge in the input channel of this intermediate equipment, the input channel that whether exists at least one to receive designated signal, if so, performs step S204, otherwise execution step S205.
In embodiments of the present invention, owing to sending the signal source of designated signal, started to transmit designated signal, if therefore this intermediate equipment can receive this designated signal, this designated signal will inevitably from least one input channel of this intermediate equipment, be detected.
Wherein, for each vision signal, preset corresponding signal identification, therefore transmitting device judges in the input channel of this intermediate equipment, whether exist the method for at least one input channel that receives designated signal to be: according to the signal identification of predefined each vision signal, judge in the input channel of this intermediate equipment, whether there is the signal identification input channel identical with the signal identification of designated signal of at least one vision signal receiving, if, determine and exist at least one to receive the input channel of designated signal, otherwise, determine and do not have the input channel that receives designated signal.
Continue, along using example, because current definite intermediate equipment is matrix switcher M3, so in the input channel of transmitting device judgment matrix switch M3, whether to exist at least one to receive the input channel of designated signal.
S204: select an input channel that receives this designated signal, and in this intermediate equipment, set up the corresponding relation of the input channel of selection and the output channel of selection, designated signal is transferred in designated display.
Continue along using example, the input channel M3I1 of hypothesis matrix switch M3 and M3I2 have received this designated signal, illustrate and in current system, had the path from signal source S1 to matrix switcher M3, therefore without searching again higher level equipment, directly in input channel M3I1 and M3I2, an optional input channel, set up the corresponding relation with the output channel M3O1 selecting, to avoid taking other input channels and the output channel of higher level equipment, reach and save the input channel of higher level equipment and the object of output channel resource.
Suppose that the input channel of selecting is M3I1, set up the corresponding relation of input channel M3I1 and output channel M3O1, make to export from M3O3 from the vision signal of M3I1 input M3, thereby designated signal is transferred on display A.
S205: select an input channel in this intermediate equipment, and the corresponding relation of the input channel of foundation selection and the output channel of selection, the equipment that input channel with selecting is connected redefines as intermediate equipment, in the intermediate equipment redefining, the output channel that selection is connected with the input channel of selecting in upper once definite intermediate equipment, and return to step S203.
In embodiments of the present invention, if there is not the input channel that receives designated signal in current definite intermediate equipment, an optional input channel in this intermediate equipment, and the corresponding relation of the output channel of selecting in this intermediate equipment in this input channel of foundation selection and step S202, and the higher level equipment that the input channel with selecting is connected redefines as intermediate equipment, in the intermediate equipment redefining, the output channel that selection is connected with the input channel of selecting in upper once definite intermediate equipment, continue to judge in the input channel of the intermediate equipment redefining, whether exist at least one to receive the input channel of designated signal, and carry out corresponding operating according to judged result, until designated signal is transferred in described designated display.
Continue along using example, the input channel that does not exist any one to receive designated signal on hypothesis matrix switch M3, illustrates in current system and does not have the path from signal source S1 to matrix switcher M3, therefore need to continue to search higher level equipment.
Concrete, first in matrix switcher M3, select an input channel, specifically can select the input channel in idle condition.Suppose that the input channel of selecting is M3I1, set up the corresponding relation of the output channel M3O1 selecting in this input channel M3I1 and step S202, so that the follow-up vision signal of inputting M3 from M3I1 can output to display A1 from M3O1.
Then, the equipment that the input channel M3I1 with selecting is connected redefines as intermediate equipment, and the equipment being connected with input channel M3I1 is matrix switcher M2, and the intermediate equipment therefore redefining is matrix switcher M2.
The output channel that input channel M3I1 with matrix switcher M3 is connected is designated as output channel M2O1, because the input channel of selecting in upper once definite intermediate equipment is M3I1, therefore in the intermediate equipment redefining (matrix switcher M2), the output channel being connected with M3I1 of selecting is M2O1, and returns to step S203.
Whether returning to step S203 is specially: in the input channel of this intermediate equipment (matrix switcher M2) that judgement redefines, exist at least one to receive the input channel of designated signal.
If, on matrix switcher M2, select an input channel that receives this designated signal, and on matrix switcher M2, the corresponding relation of the input channel of set up selecting and the output channel M2O1 of selection, makes can export from M2O1 from the designated signal of the input channel input matrix switch M2 of this selection.And due to the input channel M3I1 of M2O1 connection matrix switch M3, and on M3, set up the corresponding relation of M3I1 and M3O1, and therefore from the designated signal of M2O1 output, can pass through again matrix switcher M3, from the output channel M3O1 of M3, export.And M3O1 connects the input channel AI1 of display A, so this designated signal finally can be transferred on display A.
Otherwise, continue to adopt said method that matrix switcher M1 is redefined as intermediate equipment, and continue to judge on M1 whether have the input channel that receives designated signal, according to judged result, carry out corresponding operating, until designated signal is transferred in designated display.
In addition, in the process shown in Fig. 2, for an intermediate equipment of determining, if there are not other equipment that are connected with the input channel of this intermediate equipment, and now designated signal is not still transferred in designated display, in illustrative system, at least there is such equipment: this equipment has two higher level equipments at least.Now, again according to the method shown in Fig. 2, again set up path the transmission video signal of transmission designated signal, all paths that also traversal can be set up by the method shown in Fig. 2, until designated signal is transferred in designated display.
Pass through said method, in the time of will designated signal being transferred in designated display, can realize the path of automatically determining and set up this designated signal of transmission, and without manually determining and set up the path of this designated signal of transmission, therefore improve the efficiency of transmission video signal.
In addition, the embodiment of the present invention also provides the method for another kind of transmission video signal, as shown in Figure 3.The process of the another kind of transmission video signal that Fig. 3 provides for the embodiment of the present invention, specifically comprises the following steps:
S301: in the time of designated signal being transferred in designated display, determine the signal source that sends this designated signal.
In embodiments of the present invention, in the time will designated signal being transferred in designated display, transmitting device be first determined the signal source that sends this designated signal.
The system shown in Fig. 1 of still take describes as example, in the time the vision signal of signal source S1 output will being shown on display A, the vision signal that this signal source S1 sends is designated signal, display A is designated display, and signal source S1 is the signal source of this designated signal of definite transmission.
S302: according to the annexation between each equipment of preserving in advance, adopt establishing method to search point device based on designated display, and determine the path that point device arrives designated display of rising finding.
In embodiments of the present invention, transmitting device has been preserved the annexation between each equipment in system in advance, concrete, for certain equipment in system, transmitting device has been preserved the output channel of other equipment that the input channel of this equipment connects in advance, and the input channel of other equipment of connecting of the output channel of this equipment.
Continue, along using example, to adopt establishing method to search point device based on display A, and definite point device finding is to the path of designated display.
S303: whether the point device that rises that judgement finds is the signal source that sends designated signal, if so, performs step S304, otherwise execution step S305.
Wherein, transmitting device has been preserved for the predefined device identification of each equipment, can be according to the device identification of each equipment of preserving in advance, whether the device identification of point device that judgement finds is identical with the device identification of this signal source, if identical, determine that this plays point device is this signal source, if not identical, determine that this plays point device is not this signal source.
S304: indicate the path transmission designated signal of this signal source based on definite.
If the point device that rises finding is the signal source that sends designated signal, can indicate this signal source to play point device to this designated signal of path transmission of designated display based on what determine in step S302.
S305: again adopt this establishing method to search point device, and determine the path that point device arrives designated display of rising again finding, return to step S303.
If the point device that rises finding is not the signal source that sends designated signal, again adopt this establishing method to search point device, and determine that the point device again finding arrives the path of designated display, continue to judge whether the point device that rises again finding is the signal source that sends designated signal, and carry out corresponding operating according to judged result, until find play point device for this signal source, or till having traveled through and having adopted all the point devices that this establishing method can find.
Concrete, in above-mentioned steps S302, adopt establishing method to search point device based on this designated display, and determine find rise point device arrive designated display path process specifically as shown in Figure 4.Fig. 4 has searched point device for the employing establishing method that the embodiment of the present invention provides, and has determined that point device, to the process in the path of designated display, specifically comprises the following steps:
S3021: designated display is defined as to end device, selects an input channel in this end device.
The system shown in Fig. 1 of still take describes as example, and in the time the vision signal of signal source S1 output will being shown on display A, display A is designated display.First display A is defined as to end device, because the input channel of display A only has one (input channel AI1), therefore selects this input channel AI1.
S3022: according to the annexation between each equipment of preserving in advance, determine an intermediate equipment being connected with the input channel of selecting in this end device, record the information of the input channel of selecting in the information of this intermediate equipment, the information of output channel that this intermediate equipment is connected with the input channel of selecting in this end device and this end device.
Continue along using example, because matrix switcher M3 is connected with the input channel AI1 of selection, therefore matrix switcher M3 is defined as to intermediate equipment.And the output channel that connects AI1 due to matrix switcher M3 is M3O1, therefore the information of the intermediate equipment of record is the information of matrix switcher M3, the intermediate equipment (matrix switcher M3) of record is output channel M3O1 with the output channel that the input channel (input channel AI1) of selecting in end device (display A) is connected, and the input channel of selecting in this end device of record (display A) is AI1.
S3023: judge whether to have the equipment being connected with the input channel of this intermediate equipment, if so, perform step S3024, otherwise execution step S3025.
Continue along using example, transmitting device, according to the annexation between each equipment in the system of preserving in advance, judges whether to exist the equipment being connected with the input channel of matrix switcher M3.The equipment being connected due to the input channel with matrix switcher M3 is matrix switcher M2, therefore judgment result is that to be.
S3024: this intermediate equipment is redefined as end device, select an input channel on the end device redefining, and return to step S3022.
Continue along using example, current definite intermediate equipment is matrix switcher M3, therefore matrix switcher M3 is redefined as end device, in an input channel of the upper selection of the end device redefining (matrix switcher M3).
Suppose that the input channel of selecting is M3I1, return after step S3022, the intermediate equipment that the input channel M3I1 selecting in the end device redefining with this that transmitting device is determined is connected is matrix switcher M2, and the intermediate equipment also redefining is matrix switcher M2.The output channel being connected with the input channel M3I1 of matrix switcher M3 due to matrix switcher M2 is M2O1, so the information that transmitting device records the intermediate equipment (matrix switcher M2) redefining is again, the information of the input channel M3I1 selecting in the output channel M2O1 that the input channel M3I1 selecting in the intermediate equipment (matrix switcher M2) redefining and the end device redefining (matrix switcher M3) is connected and the end device (matrix switcher M3) that redefines.
Now, all information of transmitting device record are: the output channel M2O1 of the output channel M3O1 of the input channel AI1 of display A, matrix switcher M3, matrix switcher M3, the input channel M3I1 of matrix switcher M3, matrix switcher M2, matrix switcher M2.As can be seen here, according to all information of transmitting device record, can determine a path, the information of current record can be determined the path from matrix switcher M2 to display MA.
Because current definite intermediate equipment is matrix switcher M2, therefore transmitting device continues to judge whether to exist the equipment being connected with the input channel of matrix switcher M2, and carry out corresponding operating according to judged result, until the determination result is NO, when the determination result is NO, carry out step S3025.
S3025: using this intermediate equipment as the point device that rises finding, determine the path that point device arrives designated display of rising finding according to all information of record.
Continue along using example, transmitting device need to carry out respective handling using matrix switcher M3, matrix switcher M2, matrix switcher M1, signal source S1 as intermediate equipment successively, when using signal source S1 as intermediate equipment, in step S3023, there is not the equipment being connected with the input channel of signal source S1 in judgement, therefore using signal source S1 as the point device that rises finding.Follow-uply carry out the step S303 shown in Fig. 3, whether the point device that rises that also i.e. judgement finds is the signal source that sends designated signal.
Certainly, while adopting said method to search point device, the point device that rises finding may be not the signal source that sends designated signal, be also the step S303 shown in Fig. 3 the determination result is NO, for example adopt that the method shown in Fig. 4 finds to play a point device be signal source S2.Now, again adopt the method for Fig. 4 to search point device, and definite point device finding is to the path of designated display, also travels through all point devices that adopt the method shown in Fig. 4 to find, until the point device finding is the signal source that sends specification signal.When having traveled through all point devices that adopt the method shown in Fig. 4 to find, but while not finding yet the signal source that sends designated signal, accessed path unsuccessfully.
Further, in the step S3022 shown in Fig. 4, transmitting device records the information of intermediate equipment, the method for the information of the input channel that the information of the output channel of this intermediate equipment connection endpoint equipment and this end device connect this intermediate equipment is specifically as follows: transmitting device is for predefined stack, and the information of the input channel that the information of the output channel of the information of this intermediate equipment, this intermediate equipment connection endpoint equipment and this end device are connected to this intermediate equipment is carried out stack-incoming operation.Now, in step S3025, according to the definite point device finding of all information of record, the method to the path of designated display is specially: according to all information of preserving in this predefined stack, and the sequencing of all information of preserving in this predefined stack, determine the path that point device arrives designated display of rising finding.
It should be noted that, the method of having searched point device based on this designated display is as shown in Figure 4 the exemplary lookup method that the embodiment of the present invention provides, also can adopt in actual applications additive method to search point device based on this designated display, just repeat no longer one by one here.
