The network interface 1004 may optionally include a standard wired interface, a wireless interface. The memory 1005 may be a high speed random access memory or a stable memory such as a disk memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
It will be appreciated by a person skilled in the art that the arrangement shown in fig. 1 does not constitute a limitation of the video data transmission device, and may comprise more or less components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, identified as one type of computer storage medium, may include an operating system, a network communication module, a user interface module, and a video data transmission program.
In the set-top box shown in fig. 1, the network interface 1004 is mainly used for connecting a background server and performing data communication with the background server; the user interface 1003 is mainly used for connecting user equipment; the video data transmission apparatus calls a video data transmission program stored in the memory 1005 through the processor 1001 and executes the video data transmission method provided by the embodiment of the present invention.
Based on the above hardware structure, an embodiment of the video data transmission method of the present invention is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a video data transmission method according to a first embodiment of the present invention.
In a first embodiment, the video data transmission method includes the steps of:
step S10: and acquiring a virtual interface matching request sent by a receiving terminal, and matching a corresponding virtual output interface in a local interface according to the virtual interface matching request.
It should be understood that the execution main body of the present embodiment may be a controller provided inside a set-top box, and the set-top box controller includes a request receiving unit and a request processing unit. The request receiving unit is used for receiving request information sent by a receiving terminal. The request processing unit is used for analyzing the received request information and executing relevant operations according to the analyzed content.
It should be noted that the receiving terminal may be a terminal for receiving video data and playing the video data, such as a television, a computer, a mobile phone, a tablet, and the like. Wherein the video data refers to video data transmitted by the set-top box. The virtual interface is a software interface for receiving video data sent by the set-top box, and the virtual interface is configured in the receiving terminal. The virtual output interface is a software interface for transmitting video data to a receiving terminal, and the virtual output interface is configured in the set-top box.
It can be understood that, before performing this step, a data interaction connection needs to be established between the receiving terminal and the set-top box, where the connection may be a network connection that satisfies transmission conditions through a low-latency wireless network connection, such as a 5G network connection or a high-speed WIFI network connection.
In specific implementation, after receiving a virtual interface matching request sent by a receiving terminal through the low-latency wireless network, the set-top box controller analyzes the received virtual interface matching request to obtain a virtual output interface matching condition. And matching a corresponding virtual interface from the local interfaces of the set top box according to the matching condition obtained by analysis to be used as a virtual output interface. The virtual output interface matching condition is a condition that the receiving terminal is used for matching the virtual output interface of the set-top box, for example, an identification number of the virtual output interface.
Step S20: and acquiring the identification information of the receiving terminal, and verifying the identification information.
It should be noted that the identification information may be a unique character, a number or a verification code for the set-top box to identify different receiving terminals, and the identification information may be a PIN code. The identification information is sent by the set-top box to the registered receiving terminal when the receiving terminal is registered. When the receiving terminal is connected with the set-top box, the identification information needs to be sent to the set-top box for verification.
In specific implementation, when the virtual interface matches the request, the receiving terminal sends the identification information to the set-top box. The set-top box checks the received identification information and the identification information sent when the receiving terminal is registered, and determines whether the receiving terminal belongs to the registered receiving terminal of the set-top box. If the receiving terminal is the receiving terminal registered by the set-top box, the verification is determined to be passed, otherwise, the verification is determined not to be passed, and the subsequent relevant steps are executed.
Step S30: and when the verification is passed, selecting a target virtual transmission channel from the plurality of virtual transmission channels.
It should be noted that the virtual transmission channel is a virtual transmission channel preset in the set-top box, and the transmission channel is used for transmitting video data. The data volume of the video data is large, especially ultra-clear video blue-ray video and the like, the data transmission channel with small capacity is difficult to meet the requirements of users, and a virtual transmission channel is adopted to transmit the video data in the specific implementation process. The target virtual transmission channel is a selected virtual transmission channel set, and comprises one or more virtual transmission channels. When selecting a target virtual transmission channel, the virtual transmission channel already in video transmission needs to be actively excluded, so as to avoid interrupting video data transmission of other receiving terminals.
In the specific implementation, when the identification information passes the verification, a set of virtual transmission channels which are not in video data transmission currently is determined from the plurality of virtual transmission channels, and then a virtual transmission channel is randomly selected from the set of virtual transmission channels which are not in video data transmission for transmitting the video data which needs to be transmitted by the current receiving terminal.
Step S40: and transmitting the video data to be transmitted to the receiving terminal through the target virtual transmission channel and the virtual output interface.
It should be noted that the video data to be transmitted may be video data that needs to be received by the current receiving terminal, where the data includes one or more video data. When the current receiving terminal sends a virtual interface matching request, the virtual interface matching request comprises relevant information corresponding to the video frequency to be transmitted. The related information is information for screening video data, such as a television station corresponding to the video data.
In the specific implementation, the set top box controller obtains relevant information corresponding to the number of videos to be transmitted through analysis of the virtual interface matching request, and the set top box determines the number of videos to be transmitted required by the receiving terminal from all video data through the relevant information. After the data to be transmitted by the video are determined, the video number to be transmitted is sent to a receiving terminal through the selected target virtual transmission channel and the virtual output interface, and the receiving terminal plays the video number to be transmitted after receiving the video number to be transmitted.
The invention provides a video data transmission method, which comprises the steps of obtaining a virtual interface matching request sent by a receiving terminal, and matching a corresponding virtual output interface in a local interface according to the virtual interface matching request; acquiring identification information of a receiving terminal, and verifying the identification information; when the verification is passed, selecting a target virtual transmission channel from the plurality of virtual transmission channels; and transmitting the video data to be transmitted to a receiving terminal through a target virtual transmission channel and a virtual output interface. In the prior art, the set top box cannot experience a plurality of program information simultaneously, the invention can ensure the safety of video transmission through the verification of the identification information, and simultaneously, a plurality of paths of video data are transmitted through selecting a plurality of paths of virtual transmission channels, so that the virtual transmission channels are prevented from being independently occupied, and one set top box can simultaneously transmit a plurality of video data.
Referring to fig. 3, fig. 3 is a flowchart illustrating a video data transmission method according to a second embodiment of the present invention, which is based on the first embodiment shown in fig. 2.
In the second embodiment, before the step S10, the method further includes:
step S101': when a connection request sent by a receiving terminal is received, whether the connection request contains registration application information is detected.
It should be noted that the connection request is a request sent by the receiving terminal to the set-top box for connecting the set-top box and the receiving terminal, and the request may be a request for video data transmission. The registration application information is information which needs to be sent when the receiving terminal is connected with the set top box for the first time, and after the receiving terminal is registered in the set top box, the receiving terminal can be directly connected during later video data transmission.
In specific implementation, when receiving a connection request sent by a receiving terminal, a set-top box controller judges whether the receiving terminal has historical connection. If the connection does not exist, the connection request is analyzed, whether the connection request comprises the registration application information or not is determined, if yes, a relevant registration program is executed, and if not, no response is given.
Step S102': and if the connection request contains the registration application information, judging whether the virtual output interface responds to the connection request according to the current virtual output interface state and the current physical video output state.
It should be noted that the current virtual output interface state refers to a state where all virtual output interfaces are currently located, and includes a state of being in a video data transmission state and a state of not being in the video data transmission state. The current physical video output state is the state of video output in all the current virtual output interfaces, and comprises a video output saturated state and a video output unsaturated state. The response is a process of feeding back the reception of the connection request. When the current receiving terminal is determined to need to be registered, the current video transmission state of the set top box needs to be confirmed. When any item of the virtual output interface and the video transmission data is in a saturated state, namely when more video data transmission cannot be carried out continuously, unnecessary resource waste is avoided and no response is carried out on the connection request.
In a specific implementation, when determining that the connection information includes the registration application information, the set-top box controller confirms the states of the current virtual output interfaces one by one, and determines whether the current virtual output interface still has a virtual output interface which is not in video data transmission. And secondly, confirming the current physical video output states one by one, and determining whether the output data volume of all the current physical video output interfaces is in a saturated state. And then determining whether the receiving terminal can be connected to the set-top box according to the virtual output interface state and the physical video output state. If the request of the receiving terminal can be satisfied, the response of the feedback registration information is carried out on the connection request sent by the receiving terminal, otherwise, the response is not carried out on the connection request sent by the receiving terminal.
Step S103': and when the virtual output interface responds to the connection request, sending identification information to the receiving terminal.
It should be noted that, when the virtual output interface state and the current physical video output state of the set-top box both satisfy the state of the added device, the set-top box controller needs to invent authentication to the receiving terminal, so as to complete connection more conveniently in the subsequent connection process.
In a specific implementation, when all the virtual output interfaces include a virtual output interface which is not in a video data transmission state and the flow data output by the current physical video is not in a full state, the set top box generates corresponding identification information according to the characteristic information of the receiving terminal and sends the identification information to the receiving terminal.
The invention provides a video data transmission method, which comprises the steps of obtaining a virtual interface matching request sent by a receiving terminal, and matching a corresponding virtual output interface in a local interface according to the virtual interface matching request; acquiring identification information of a receiving terminal, and verifying the identification information; when the verification is passed, selecting a target virtual transmission channel from the plurality of virtual transmission channels; and transmitting the video data to be transmitted to a receiving terminal through a target virtual transmission channel and a virtual output interface. In the prior art, the set top box cannot experience a plurality of program information simultaneously, the invention can ensure the safety of video transmission through the verification of the identification information, and simultaneously, a plurality of paths of video data are transmitted through selecting a plurality of paths of virtual transmission channels, so that the virtual transmission channels are prevented from being independently occupied, and one set top box can simultaneously transmit a plurality of video data.
Referring to fig. 4, fig. 4 is a flowchart illustrating a video data transmission method according to a third embodiment of the present invention, which is proposed based on the first embodiment shown in fig. 2.
In the third embodiment, the step S40 includes:
step S401: and adding the target virtual transmission channel into the established communication connection between the virtual output interface and the receiving terminal.
It should be noted that the established pass connection is an interactive connection for performing a virtual interface matching request between the set top box and the receiving terminal, and the connection is only used for interaction of information such as matching information, registration application information, control information and the like between the set top box and the receiving terminal, and cannot be used for transmission of video data. After the target virtual transmission channel has been determined, it is necessary to combine the target virtual transmission channel with the established current connection for the transmission of video data.
In a specific implementation, the selected target virtual transmission channel is connected with the front end of the virtual output interface, and is added to the established communication connection. The rear end of the virtual output interface is connected with the virtual connection interface of the receiving terminal, so that the connection between the target virtual transmission channel and the receiving terminal is realized.
Step S402: and transmitting the video data to be transmitted to the virtual output interface through the target virtual transmission channel.
It should be noted that the received video data to be transmitted is video data in the video data sent by the receiving communication satellite. The set top box needs to receive video data sent by the communication satellite, selects corresponding video frequency to be transmitted according to the request information of the receiving terminal, and sends the video frequency to be transmitted to the receiving terminal for playing. For example, when a set-top box is used to watch television programs, a communication satellite signal receiving device is required to be installed, the device is used to receive data information of a communication satellite, then the set-top box selects a corresponding television station according to a remote control instruction of a user, and then program information of the television station is sent to a television for playing.
In specific implementation, the video data to be transmitted needs to be transmitted to a corresponding virtual transmission interface on the set top box through the target virtual transmission channel, the transmission interface continues to compress and package the video data to be transmitted, and the obtained compression package is sent to a corresponding receiving terminal.
Step S403: and controlling the virtual output interface to send the video data to be transmitted to the receiving terminal.
It should be noted that the virtual output interface and the receiving terminal are connected through a wireless network without delay, and in this embodiment, in order to ensure timeliness of transmission, the virtual output interface and the receiving terminal may be connected through a 5G network.
In the specific implementation, the virtual output interface performs a series of processing such as compression and packaging on the received video data to be transmitted, sends the processed compressed packets to the receiving terminal, and when receiving the compressed packets, the receiving terminal performs inverse processing such as decompression on the compressed packets and then plays the video data to be transmitted.
In this embodiment, a video data transmission method is provided, where a virtual interface matching request sent by a receiving terminal is obtained, and a corresponding virtual output interface is matched in a local interface according to the virtual interface matching request; acquiring identification information of a receiving terminal, and verifying the identification information; when the verification is passed, selecting a target virtual transmission channel from the multiple virtual transmission channels; and transmitting the received video frequency to be transmitted to a receiving terminal through a target virtual transmission channel and a virtual output interface. In the prior art, a set top box cannot experience a plurality of program information simultaneously, the embodiment can ensure the safety of video transmission by checking identification information, and simultaneously, video data is transmitted by selecting one virtual transmission channel, so that the virtual transmission channel is prevented from being occupied independently, and a plurality of video data are transmitted by one set top box simultaneously.
Referring to fig. 5, fig. 5 is a flowchart illustrating a video data transmission method according to a fourth embodiment of the present invention, which is proposed based on the first embodiment shown in fig. 2.
In the fourth embodiment, the step S40 is followed by:
step S401': and acquiring the control information of the receiving terminal.
The control information is information for controlling the set-top box to switch the video data, and the information may be transmitted by the control device of the receiving terminal. In a specific implementation process, a request receiving unit of the set-top box receives control information sent by a receiving terminal through a wireless network without time delay.
Step S402': and adjusting parameters of the target virtual transmission channel according to the control information to obtain the adjusted target virtual transmission channel.
It should be noted that the parameter adjustment is to adjust the parameter of the video transmission data selected by the target virtual transmission channel, so that the target virtual transmission channel interrupts the current video data transmission and connects to the updated video data for transmission.
During specific implementation, the set-top box controller analyzes the received control information to obtain adjustment information related to parameter adjustment of the target virtual transmission channel. And adjusting the parameters of the target virtual transmission channel according to the analyzed adjustment information to obtain the target virtual transmission channel for updating the video data to be sent.
Step S403': and updating the video data to be sent according to the adjusted target virtual transmission channel.
It should be noted that the updated video data to be transmitted is the video data that the user wants to replace, for example, during watching tv, when a certain tv station is advertising, we usually replace the tv station to look for other tv programs to watch. The updated video data to be transmitted may be other found television programs or other similar video resources.
In the specific implementation, the video data to be updated and sent, which are needed by the user, are searched from all the video data according to the adjusted parameter characteristics of the target virtual transmission channel and sent.
Step S404': and transmitting the updated video data to the receiving terminal through the adjusted target virtual transmission channel and the virtual output interface.
It should be noted that, after the video data is replaced, the replaced video data needs to be transmitted to the receiving terminal through the adjusted transmission channel.
In concrete implementation, after determining updated video data to be transmitted, the set-top box controller transmits the video data to be transmitted to the receiving terminal through the adjusted target virtual transmission channel and the virtual output interface, and the receiving terminal plays the video data to be transmitted after receiving the video data to be transmitted.

In the prior art, a set top box cannot experience a plurality of program information simultaneously, the embodiment can ensure the safety of video transmission by checking identification information, and simultaneously, video data is transmitted by selecting one virtual transmission channel, so that the virtual transmission channel is prevented from being occupied independently, and a plurality of video data are transmitted by one set top box simultaneously.
Furthermore, an embodiment of the present invention further provides a storage medium, where a video data transmission program is stored, and the video data transmission program, when executed by a processor, implements the steps of the video data transmission method as described above.
In addition, referring to fig. 6, an embodiment of the present invention further provides a video data transmission device, where the set-top box includes: the system comprises an interface matching module 10, an identification information checking module 20, a channel selecting module 30 and a data transmission module 40;
