Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
The existing video monitoring system has strong dependence on a decoder when the video decoding is controlled on the wall, the decoding can be programmed by software, the decoder is required to support image processing, and the system has the functions of network communication, video output and the like, so that the system has high requirement on the hardware of the decoder. However, too high hardware requirements limit the scalability of the system. The video decoding on-wall control method provided by the embodiment of the application aims to solve the technical problem that the expandability of a system is limited due to high requirements on decoder hardware and strong dependency in the existing decoding on-wall system.
The video decoding on-wall control method provided by the embodiment of the application is applied to a general PC host, and one or more decoding ends are arranged in the PC host based on a PCIE interface widely applied in the PC host, so that the host can perform the video decoding on-wall function in an extensible manner. The application uses the scene including but not limited to security protection control field. Referring to fig. 1, fig. 1 is a flowchart illustrating a basic method of controlling a video decoding on a wall according to an embodiment of the present application, which is detailed as follows:
in step S101, a communication channel connecting the main control end and the decoding end is established to determine the decoding end paired with the main control end.
Decoding the video image on the wall is one of the most important steps in the process that the user watches the video image collected by the front-end equipment through the television wall, and specifically means that the video image obtained after decoding by the decoder is displayed on a window of the television wall through a physical interface of the decoder.
In this embodiment, the main control end is a control end of the PC host, and is configured to control and manage the PC host, where the main control end configures a decoding end for the PC host, transmits one or more video data received by the PC host to the decoding end, and controls the decoding end to decode the one or more video data received by the PC host, so as to implement operations of video decoding and loading on a wall. In this embodiment, the PC host is provided with at least one decoding end, and before performing the video decoding on-wall operation, a communication channel connecting the main control end and the decoding end is established in the PC host, so as to configure a corresponding decoding end for the video decoding on-wall operation. Specifically, when configuring the decoding end, configuring a certain IP address for the decoding end performing the video decoding on-wall operation by using a protocol including but not limited to TCP/IP, and enabling the IP address not to conflict with IP addresses of other network devices in the local area network and other decoding ends on the PC host, thereby enabling a communication channel to be established between the main control end and the decoding end. Therefore, the communication channel between the main control end and the decoding end is established in a TCP/IP protocol communication mode, and the requirement on a network environment can be reduced.
In step S102, a pre-stored decoding program is obtained from the PC host through the communication channel and subjected to mirror loading processing.
In this embodiment, before the main control end and the decoding end establish the communication channel, the decoding end disposed in the PC host does not have a decoding function, and needs to be configured to have the decoding function.
In this embodiment, a decoding program, including but not limited to a programming program, an image processing program, and the like, which is required when a decoding side performs a decoding operation, is previously stored in the PC host. After a communication channel is established between the main control end and the decoding end through the step S101, the decoding end can obtain a decoding program required for performing a video decoding on-wall operation from the PC host through the established communication channel and perform mirror loading processing, so that the decoding end has a decoding function corresponding to the mirror-loaded decoding program, and thus the decoding end can perform a video decoding on-wall decoding operation.
It can be understood that, in this embodiment, before the communication channel is established with the main control terminal, the decoding terminal is not configured with a decoding program, and the decoding program required for performing the decoding operation is stored in the database preset by the PC host. After the decoding end establishes a communication channel with the main control end, the decoding end can obtain a decoding program required for executing decoding operation from a database preset by the PC host to perform mirror loading processing, so as to implement functional configuration of the decoding end. Therefore, the unified management of the decoding program can be realized, for example, when the decoding program needs to be upgraded, only the database of the PC host needs to be upgraded, and the PC host needs to be restarted, so that the decoding end does not need to be upgraded one by one, and the operation is simple and convenient.
In step S103, the decoding program decodes the video data to be decoded acquired from the PC host, generates a playable video file, and performs on-wall display.
In this embodiment, after the functional configuration of the decoding end is completed in step S102, the main control end transmits the video data to be decoded received by the PC host to the decoding end through a communication channel between the main control end and the decoding end, which is established by a protocol, so that the decoding end obtains the video data to be decoded from the PC host. And then, the decoding end decodes the video data to be decoded acquired from the PC host through the decoding program to generate a playable video file for on-wall display and perform on-wall display operation on the playable video file. Therefore, the process that the video data to be decoded are decoded to generate the playable video file based on the PC host, so that the playable video file can be output to the display end to be displayed on the wall.
In the video decoding on-wall control method provided in the above embodiment, after a communication channel connecting a host computer end and a decoding end is established, a pre-stored decoding program is acquired from the PC host computer through the communication channel to perform function configuration on the decoding end, so that the decoding end has a decoding function, and the decoding end performs decoding processing on video data to be decoded acquired from the PC host computer through the decoding program to generate a playable video file and perform on-wall display. Therefore, based on the PC host, one or more decoding ends can be arranged in the PC host according to the actual requirements of users, the expandability is strong, the hardware quantity required by the decoding ends can be configured in a targeted manner according to the number of channels required by the current video decoding on-wall operation, the decoding ends are set to be configurable, the decoding on-wall requirements of different scenes are met, the flexibility is good, the functional configuration of the decoding ends is realized by acquiring decoding programs required by executing the decoding operation from a database preset by the PC host and carrying out mirror image loading processing, the hardware requirements on the decoding ends are reduced, and the upgrading and maintenance of software are simplified.
In some embodiments of the present application, please refer to fig. 2, and fig. 2 is a schematic flowchart illustrating a method for establishing a communication channel between a connection main control end and a decoding end in a video decoding on-wall control method according to an embodiment of the present application. The details are as follows:
in step S201, receiving a UDP broadcast packet of the master control end, where the UDP broadcast packet includes a first network segment corresponding to the PCIE network card identified from the PC host;
in step S202, the acquired first network segment is configured to an address code pre-configured by the decoding end itself to generate an IP address corresponding to the decoding end, so as to establish a communication channel connecting the main control end and the decoding end.
In this embodiment, the decoding end always tries to receive the UDP broadcast packet sent by the main control end, that is, as long as the main control end sends the UDP broadcast packet containing the first network segment, the decoding end can obtain the UDP broadcast packet and timely respond to the communication connection request of the main control end. And after the decoding end obtains the UDP broadcast message, a first network segment corresponding to the PCIE network card is obtained by analyzing the UDP broadcast message. Furthermore, each decoding end is pre-configured with a corresponding address code according to its own hardware configuration, and the address code is a unique identifier for representing the decoding end. After the decoding end receives the UDP broadcast message, the decoding end may write the first network segment obtained from the UDP broadcast message into an address code pre-configured by the decoding end, so as to generate an IP address corresponding to the decoding end, and further enable the decoding end to establish a communication connection with the main control end.
In this embodiment, for one or more PCIE interfaces arranged in the PC host, each PCIE interface is correspondingly provided with a unique card slot identifier, when a PCIE network card is inserted into a PCIE interface in the PC host, the PC host configures an IP address of a network device corresponding to the PCIE network card to a first network segment corresponding to the card slot identifier, and then the master control end designates to send a UDP broadcast packet containing the first network segment corresponding to the card slot identifier from the PCIE network card. Therefore, due to the fact that the card slot identifiers of the PCIE interfaces are different, when the PCIE network card is inserted into different PCIE interfaces in the PC host, the first network segments contained in the UDP broadcast messages sent by the PCIE network card are different. Moreover, different decoding ends in the PC host are correspondingly provided with unique address code identifications. Therefore, when different decoding ends receive the UDP broadcast message, the communication channel which is correspondingly established between the different decoding ends and the main control end is independent and does not conflict with other network equipment in the local area network and the IP addresses of other decoding ends on the PC host.
In some embodiments of the present application, please refer to fig. 3, and fig. 3 is a flowchart illustrating a method for generating a UDP broadcast message in a video decoding on-wall control method according to an embodiment of the present application. Based on the main control end, when establishing communication connection with the decoding end, the details are as follows:
in step S301, monitoring whether a PCIE network card is inserted into a PCIE interface provided in the PC host;
in step S302, when a PCIE network card is inserted into the PCIE interface, identifying a card slot identifier of the PCIE interface;
in step S303, the IP of the PCIE network card is configured as the first network segment associated with the card slot identifier, so that the master control end designates to send a UDP broadcast message including the first network segment from the PCIE network card.
In this embodiment, the PC host is provided with one or more PCIE interfaces, and each PCIE interface is correspondingly provided with a unique slot identifier. The PCIE interface is used for inserting a PCIE network card, one end of the PCIE network card is connected with a switch, and the switch is connected with one or more decoding ends in a downward connection mode. Therefore, the main control end monitors whether a PCIE network card is inserted into a PCIE interface in the PC host in time, and when the PCIE interface in the PC host is monitored to be inserted with the PCIE network card, a communication channel between the main control end and the decoding end is established. Further, in this embodiment, for one or more PCIE interfaces set in the PC host, each PCIE interface has its corresponding card slot identifier, and the card slot identifiers of each PCIE interface are not repeated. Therefore, when it is monitored that a PCIE network card is inserted into the PCIE interface, the master control end may configure the IP address of the network device corresponding to the PCIE network card into the first network segment corresponding to the card slot identifier by identifying the card slot identifier of the PCIE interface, and then the master control end designates to send a UDP broadcast message from the PCIE network card, and may send a UDP broadcast message containing the first network segment corresponding to the PCIE interface card slot identifier inserted into the PCIE network card, so that the master control end requests to establish communication connection with the decoding end in a UDP broadcast message manner. Specifically, when establishing a communication connection, the main control end first sends a UDP broadcast message, and then waits for the decoding end to respond to the UDP broadcast message, and after receiving the UDP broadcast message sent by the main control end, the decoding end establishes a communication channel connecting the main control end and the decoding end by acquiring a first network segment included in the UDP broadcast message and writing the acquired first network segment into an address code pre-configured for the decoding end, so that the communication channel established between the main control end and the decoding end is used to implement data transmission through a TCP/IP protocol.
For example, three PCIE interfaces are arranged in the PC host, where card slot identifiers corresponding to the three PCIE interfaces are a1, a2, and A3, respectively. When it is monitored that a PCIE network card is inserted into the PCIE interface and the card slot identifier corresponding to the PCIE interface into which the PCIE network card is inserted is identified as A1, the IP address of the network device corresponding to the PCIE network card is configured to be the first network segment corresponding to the card slot identifier A1, for example, 240.0.a 1.100. At this time, the main control end designates to send a UDP broadcast message from the PCIE network card, so as to send a UDP broadcast message containing a 240.0.a1.100 network segment, so as to request to establish a communication connection with the decoding end. In this way, after the decoding end receives the UDP broadcast message sent by the main control end, a communication channel connecting the main control end and the decoding end is established by acquiring the first network segment contained in the UDP broadcast message and writing the acquired first network segment into the address code pre-configured for the decoding end, so that the communication channel established between the main control end and the decoding end realizes data transmission through a TCP/IP protocol.
In the above embodiment, a first network segment corresponding to a PCIE interface card slot identifier is configured for a network device corresponding to a PCIE network card according to the PCIE interface card slot identifier inserted in the PCIE network card, and then the master control end designates to send a UDP broadcast message from the PCIE network card, so that the UDP broadcast message includes the first network segment corresponding to the PCIE interface card slot identifier, and for different decoding ends in the PC host, each decoding end is configured with a corresponding address code identifier in advance according to its own hardware configuration as a unique identifier of the decoding end, when the master control end and the decoding end establish a communication channel, the decoding end may generate an IP address corresponding to the decoding end by acquiring the UDP broadcast message sent by the master control end and identifying the first network segment included in the UDP broadcast message, writing the acquired first network segment into the address code preconfigured by the decoding end itself, therefore, the main control end in the PC host can adaptively configure the IP address of the decoding end without manually configuring the IP address for each decoding end independently, thereby omitting the fussy process of configuring the IP address of the decoding end and improving the execution efficiency of executing the video decoding on-wall operation.
In some embodiments of the present application, please refer to fig. 4, where fig. 4 is a flowchart illustrating a method for configuring an address code for a decoding end itself in a video decoding on-wall control method according to an embodiment of the present application. The details are as follows:
in step S401, a level value input by the GPIO corresponding to the decoding end is obtained;
in step S402, identifying sequence number information of the decoding end itself according to the level value;
in step S403, the sequence number information is written into a preset second network segment to generate an address code corresponding to the decoding end.
In this embodiment, since the hardware configuration of the periphery of each decoding end is different, the level value of the GPIO input corresponding to each decoding end is correspondingly different. Wherein the level is the relative ratio of the electric quantity of two or more points in the circuit under the same impedance.
