Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a flowchart of an apparatus detection method provided in an embodiment of the present invention is shown, and is applied to a video signal receiving end, where the method includes:

and S100, receiving the video signal sent by the video signal sending end.

In the process of transmitting video signals, each frame of video frame comprises a vertical blanking area and an effective video data area, the vertical blanking area can be used for carrying other information except video data to realize the transmission of other information, for example, the vertical blanking area is used for carrying control information for controlling a pan-tilt camera to move up and down and left and right to realize the transmission of the control information.

The vertical blanking area may include a plurality of blanking lines, and when the storage resource of one blanking line is insufficient, the information to be transmitted may be carried by the plurality of blanking lines, and when the storage resource of the blanking area of one video frame is insufficient, the information to be transmitted may be carried by the plurality of video frames.

S110, first information carried in a vertical blanking area of the video signal is obtained, wherein the first information is as follows: and the preset information for preventing the video signal sending end from the goods mixing behavior.

Specifically, the first information may include a plurality of bytes, each byte representing a different meaning; for example, the first byte represents the type of video signal sent by the video signal sending end; the second byte represents the language used by the video signal transmitting end, such as Chinese, English; the third byte represents a sales area or the like of the video signal transmitting end.

In one implementation, a video signal sending end and a video signal receiving end may pre-specify a blanking line for carrying first information, and when the video signal sending end sends a video signal to the video signal receiving end, the video signal sending end may carry the first information through the pre-specified blanking line. When the blanking line for carrying the first information is agreed, one blanking line may be agreed to carry the first information, or multiple blanking lines may be agreed to carry the first information, for example, multiple blanking lines are agreed, and each blanking line carries one byte included in the first information.

In another implementation manner, the video signal receiving end and the video signal transmitting end may determine the target blanking line for carrying the first information in a negotiation manner.

Specifically, before sending the video signal carrying the first information in the blanking region to the video signal receiving end, the video signal sending end may send the video signal carrying the configuration information in the preset blanking line in the vertical blanking region to the video signal receiving end; the preset blanking line is a blanking line which is predetermined by the video signal receiving terminal and the video signal transmitting terminal and is used for carrying configuration information, for example, the video signal receiving terminal and the video signal transmitting terminal can determine the 6 th blanking line in the video signal to be used for carrying the configuration information; the configuration information includes information of a first type of blank line that is not occupied at a sending end of the video signal, and specifically, the configuration information may include: specific row, total row, etc. For example, the configuration information includes: 6. 7, 8, 9, 4; the first type of blanking lines that indicate that the transmitting end of the video signal is unoccupied include: lines 6, 7, 8, 9 blank lines.

Correspondingly, before S100, the video signal receiving end receives the video signal carrying the configuration information in the preset blanking line in the vertical blanking area sent by the video signal sending end; then the video signal receiving end can confirm whether the first type of blanking line at the video signal receiving end is occupied, after the confirmation result is obtained, the video signal receiving end can not send the confirmation result to the video signal sending end, at the moment, the video signal receiving end and the video signal sending end can be well defined in advance, the video signal sending end can confirm that the first type of blanking line at the video signal receiving end is unoccupied within a certain time length, such as 5 seconds, and when the confirmation result sent by the video signal receiving end is not received, so that the first type of blanking line is determined to be the target blanking line for carrying the first information;

the video signal receiving end confirms whether the first class blanking line at the video signal receiving end is occupied or not, and after a confirmation result is obtained, the video signal receiving end can also send the confirmation result to the video signal sending end, and the confirmation result can comprise two conditions at the moment;

one is as follows: under the condition that a first blanking line of a video signal receiving end is unoccupied, the video signal receiving end sends a confirmation result representing that the first blanking line is unoccupied to a video signal sending end, and after the video signal sending end receives the confirmation result, the first blanking line is determined as a target blanking line used for carrying first information;

the second step is as follows: in the case that the first type of blanking line at the receiving end of the video signal is occupied, the target blanking line for carrying the first information can be determined by the following two implementation manners:

in one implementation mode, a video signal receiving end sends a confirmation result representing that a first type of blanking line is occupied to a video signal sending end, the video signal sending end can confirm the first type of blanking line which is not occupied at the video signal sending end again after receiving the confirmation result, then sends a video signal carrying configuration information in a preset blanking line in a field blanking area to the video signal receiving end again, and the video signal receiving end judges whether the first type of blanking line is occupied at the video signal receiving end again until the first type of blanking line which is not occupied at the video signal sending end and the video signal receiving end is confirmed, and determines the type of blanking line as a target blanking line for carrying the first information.

In another implementation, the video signal receiving end may first determine the second type of blank line that is not occupied at the video signal receiving end, then, the confirmation result containing the information of the second type blanking lines is sent to a video signal sending end which sends the second type blanking lines to a video signal sending end, after confirming whether the second class blanking line is occupied or not at the video signal sending end and obtaining the confirmation result, the video signal sending end can not send the confirmation result to the video signal receiving end, at this time, the video signal receiving end and the video signal sending end can be well defined in advance, when the video signal receiving end does not receive the confirmation result sent by the video signal sending end within a certain time length, such as 5 seconds, the video signal receiving end confirms that the second blanking line is a target blanking line used for carrying the first information, so as to obtain the first information in the second blanking line of the subsequently received video signal.

The video signal sending end confirms whether the second blanking line is occupied or not, and after a confirmation result is obtained, the video signal sending end can also send the confirmation result to the video signal receiving end, and the confirmation result can comprise two conditions;

one is as follows: under the condition that a second blanking line of a video signal sending end is unoccupied, the video signal sending end sends a confirmation result that the first blanking line is unoccupied to a video signal receiving end, and after the video signal receiving end receives the confirmation result, the video signal receiving end confirms that the second blanking line is a target blanking line used for carrying first information so as to obtain the first information in the second blanking line of a subsequently received video signal;

the second step is as follows: in the case that the second type of blanking line at the sending end of the video signal is occupied, the target blanking line for carrying the first information can be determined by the following two implementation manners:

in one implementation, a video signal sending end sends a confirmation result that a second type of blanking line is occupied to a video signal receiving end, and the video signal receiving end can send the second type of blanking line which is not occupied at the video signal receiving end to the video signal sending end again after receiving the confirmation result, so that the video signal sending end judges whether the second type of blanking line is occupied at the video signal sending end again until the second type of blanking line which is not occupied at the video signal sending end is confirmed, and the video signal sending end confirms the second type of blanking line as a target blanking line for carrying first information;

in another implementation manner, the video signal sending end may confirm the first type of blank line that is not occupied at the video signal sending end again, then send the video signal carrying the configuration information in the preset blank line in the field blank area to the video signal receiving end, and the video signal receiving end judges again whether the first type of blank line is occupied at the video signal receiving end until the first type of blank line that is not occupied at both the video signal sending end and the video signal receiving end is confirmed, and determines the type of blank line as a target blank line for carrying the first information;

it should be noted that the first-type blanking line is a generic name of a blanking line which is sent from a video signal sending end to a video signal receiving end and is not occupied in video signal sending, and specific lines included in every two times of sending of the first-type blanking line from the video signal sending end to the video signal receiving end are not completely the same, for example, the first-type blanking line sent to the video signal receiving end for the first time: 6. lines 7, 8 and 9, the first blanking behavior transmitted to the video signal receiving end for the second time is: 6. lines 7, 9, 10. Accordingly, the second type of blanking lines is a general term for the blanking lines which are not occupied at the video signal receiving end and are sent from the video signal receiving end to the video signal sending end.

In an implementation manner of the embodiment of the present invention, under the condition that the first-type blanking line of the video signal receiving end is not occupied, the video signal receiving end may send a request for acquiring the first information to the video signal sending end after sending the confirmation result to the video signal sending end; the video signal receiving end can also directly send a request for acquiring the first information to the video signal sending end, after the video signal sending end receives the acquisition request, the video signal sending end confirms that the first blanking line is not occupied, then the video signal carrying the first information in the target blanking line is sent to the video signal receiving end corresponding to the request, and based on the result, the video signal receiving end receives the video signal carrying the first information in the target blanking line sent by the video signal sending end after receiving the request.

S120, detecting whether the first information is matched with second information, wherein the second information is: the preset information for preventing the video signal receiving end from goods mixing behavior is executed, and S130 is executed to determine that the video signal sending end is matched with the video signal receiving end when the detection result is yes; and when the detection result is negative, determining that the video signal sending end is not matched with the video signal receiving end.

Corresponding to the first information, the second information may also include a plurality of bytes, each byte corresponds to the meaning represented by each byte included in the first information, for example, the first byte in the first information represents the type of the video signal transmitted by the video signal transmitting end, and correspondingly, the first byte in the second information represents the signal type of the video signal processed by the video signal receiving end; the second byte in the first message represents the language used by the sending end of the video signal, and correspondingly, the second byte in the second message represents the language used by the receiving end of the video signal.

Specifically, only when the first information and the second information are completely the same, it can be determined that the video signal sending end is matched with the video signal receiving end, that is, the video signal sending end or the video signal receiving end has no goods mixing action; if the first information and the second information are not completely the same, it indicates that the video signal sending end or the video signal receiving end has a series behavior, and accordingly, the video signal receiving end may not display the picture corresponding to the video signal sent by the video signal sending end.

In one implementation, when the first information and the second information both include a plurality of bytes, in the process of detecting whether the first information matches with the second information, a value stored in each byte included in the first information may be acquired; then judging whether the acquired numerical values are respectively matched with the numerical values stored in the bytes contained in the second information; and if so, judging that the first information is matched with the second information.

In order to enhance the security of the first information during transmission, in an implementation manner, when a video signal sending end sends a video signal carrying the first information in a target blanking line to a video signal receiving end, the video signal sending end may first determine an information header of the first information, where the information header includes an order of reading values from each byte included in the first information, for example, a value stored in a first byte included in the first information is 0xaa, and when the reading order is forward reading, the value of the first byte is 0 xaa; when the reading order is reverse, the value of the first byte is aax 0. After the video signal sending end determines the information head of the first information, the video signal sending end sends the video signal carrying the information head and the first information in the target blanking line to the video signal receiving end, and any blanking line in the target blanking line can be selected to carry the information head;

accordingly, in the process of acquiring the numerical values of the bytes included in the first information, the video signal receiving end needs to acquire the information header of the first information first, and then acquire the numerical values of the bytes included in the first information according to the reading sequence included in the information header.

In another implementation manner, when the video signal transmitting end transmits a video signal carrying first information in a target blanking line to the video signal receiving end, the video signal transmitting end may invert 0 and 1 binary data of values stored in each byte included in the first information; and then sending the video signal carrying the first information after the binary data inversion in the target blanking line to a video signal receiving end.

Correspondingly, in the process of acquiring the numerical value of each byte contained in the first information, the video signal receiving end needs to perform 0 and 1 inversion on binary data of the numerical value stored in each byte contained in the first information; and then the numerical values stored in the respective bytes after the inversion of 0 and 1 are obtained.

In each scheme provided by the embodiment of the invention, the video signal sending end obtains the video signal carrying the first information in the vertical blanking area, and sends the video signal to the video signal receiving equipment, and after the video signal receiving equipment receives the video signal, the first information is matched with the second information, and as the first information is information for preventing the video signal sending end from having the goods mixing behavior and the second information is information for preventing the video signal receiving end from having the goods mixing behavior, when the first information is matched with the second information, the video signal sending end and the video signal receiving end do not have the goods mixing behavior.
