Detailed Description
The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.
First, the terms involved will be explained.
Referring to fig. 1, a media-merging system, in a simpler structure, may be understood as being composed of a screen and a plurality of terminals, where a display area on the screen may be divided into a plurality of sub-display areas, each sub-display area may be capable of displaying independently, and displayed content is provided by a terminal, and generally, each terminal provides display content for a sub-display area on a screen.
The network flow refers to data flow transmitted by means of a network, network transmission data are transmitted by means of network cables, switches, local area network equipment, servers and the like, data exchange is performed between hardware by means of network cables or wireless networks, the hardware cost is low, the transmission range is large, and the influence of space limitation is very small.
At present, most terminals used in a media-oriented system are computers, the output of a computer to a screen depends on a display card, regardless of an integrated display card or an independent display card, generally, one display card is generally only equipped with one interface, and the interface needs to output through a VGA line, an HDMI line or a DP line, and the like, so that the hardware cost of the method is high, and the transmission distance is also limited by hardware, for example:
ten display areas are divided on one screen, ten terminals need to be equipped, a data line (VGA line, HDMI line or DP line, etc.) needs to be connected between each terminal and the screen, and when the distance between the terminal and the screen is long, the length of the data line is increased.
It should be understood that each terminal is expensive, and as the number of terminals increases, the use cost increases, and even if a plurality of video cards are installed on one terminal (the number of installed video cards is very limited), the use cost increases, which leads to the rise of the final use cost.
It should also be understood that the price of VGA line, HDMI line or DP line is relatively high, for example, a ten meter HDMI line, which is sold at about one hundred yuan, and the price will rise with the increase of definition requirement, but the network line with the same length is less than ten yuan, and the transmission bandwidth can meet the requirement of high definition.
In addition, from the viewpoint of later use cost, excessive hardware inevitably brings extra management cost, and maintenance, replacement and the like of the hardware are not small burdens.
According to the technical scheme shown in the embodiment of the application, the display content is transmitted to the screen in a mode of converting the display content into the network stream, dependence on multiple terminals, a display card, special wires (VGA wires, HDMI wires or DP wires and the like) and the like can be eliminated, and the transmission distance can be increased.
Referring to fig. 2, a data transmission method disclosed in the embodiment of the present application includes the following steps:
s101, acquiring first selection information, wherein the first selection information points to window information in information source information;
s102, continuously acquiring content information in the window information;
s103, coding the continuously acquired content information to generate continuous network stream information; and
and S104, sending the generated continuous network flow information through the network.
Specifically, in step S101, a certain window information can be obtained through the first selection information, where the window information is derived from a source information corresponding to a terminal capable of providing the window information.
In step S102, content information in the acquired window information is continuously captured to form continuous content information, and it should be understood that, for a window, the displayed content may be static or dynamic, but from the viewpoint of time, the displayed content should be continuous regardless of whether static or dynamic.
In some possible implementations, the window may be a browser window, a player window, or an office software window, among others.
In step S103, the continuously acquired content information is encoded to generate continuous network stream information, and the encoding is used to prepare for a subsequent transmission process.
It should be understood that the content information cannot be directly transmitted, for example, optical signals are transmitted through optical fibers, analog signals are transmitted through network cables, and signals are transmitted through wireless network cards by using electromagnetic waves, so that the continuously acquired content information needs to be encoded, that is, converted from one form or format to another form or format, so as to meet the subsequent transmission requirements.
The content in step S104 is to send out the generated continuous network stream information, and as for the sending form, the specific selection may be performed according to the actual use environment through a wired network or a wireless network.
The virtual environment is that data are transmitted between the terminal and the screen in a network cable mode, and the display card and the special data cable are directly abandoned in the connection mode, so that the connection mode is obvious, the dependence degree on hardware is lower, the erection is more convenient, and the hardware cost is lower. Referring to fig. 3, if the wireless network is used for the erection, the dependence on hardware can be further reduced, and meanwhile, the transmission distance is also increased, and even the remote transmission can be realized.
In addition, the network transmission is less limited by distance, the terminal can be projected on the screen in a remote network mode, and the terminal and the screen can be arranged at will in a place which can be covered by the network, so that the limitation of space is avoided.
In another usage scenario, for example, fast deployment is required, for an original converged media system, a connection line needs to be established between each terminal and a screen, and a connection between the terminals and the screen needs to be point-to-point, but if a network is used for transmission, for the terminals, referring to fig. 4 and 5, a router or a splitter or the like can be used as a relay to aggregate data and then transmit the aggregated data to the screen in a unified manner, instead of requiring separate data transmission with the screen, which is more flexible.
In the process of arrangement, the network cable can be manufactured at any time even according to the using length, and if the wireless network mode is used for transmission, the flexibility of arrangement can be further improved.
Referring to fig. 6 and fig. 7, as a specific embodiment of the data transmission method provided by the application, the following steps are added:
s301, acquiring one or more pieces of display area information, wherein each piece of display area information comprises one or more pieces of sub-display area information;
s302, third selection information is obtained, and the third selection information points to information of one sub-display area; and
s303, sending the network flow information corresponding to the first selection information to display area information pointed by the third selection information;
wherein, the source of the display area information is one or more.
The content in steps S301 to S303 is to transmit the generated network flow information to any display area to be displayed, so that the network flow information can be directionally transmitted.
Specifically, in step S301, one or more pieces of display area information are obtained, each piece of display area information includes one or more pieces of sub-display area information, and the source of the display area information may be one or more.
It should be understood that the display area is provided by the screen, and if there are multiple screens in an application scene at the same time, the screens can be accessed at the same time to control the displayed content.
It should also be understood that for a block of a screen, its display area may be divided, for example, into NxN blocks of display areas.
The content in step S302 is to obtain third selection information, where the third selection information points to one sub-display area information, and the sub-display area information may point to any one of the sub-display area information obtained in step S301.
Then, in step S303, the network flow information corresponding to the first selection information is sent to the display area information pointed by the third selection information, so that the generated network flow information is directionally transmitted, and the generated network flow can be sent to the display area on any screen connected to the terminal.
As a specific embodiment of the data transmission method, the state of the window information in step S101 is expanded, and may be a display state, a hidden state, a blocking state, or a partial blocking state.
It should be understood that most of the existing projection methods use a point-to-point method, that is, what content is displayed on the terminal and what content is displayed on the projected screen, but this method will limit the terminal in this usage environment and cannot perform other tasks.
For a window, the states of the window in the terminal are various, and may be a display state (the window is maximized or can be fully seen in a display area on the terminal), a hidden state (minimized), an occlusion state (located behind other display windows), a partial occlusion state (a partial area is located behind other display windows), and the like, which may exist, and if the acquisition of the display content is adjusted to a certain window, the window may be released for the terminal.
Specifically, for a window, when it is in the working state, the content displayed is determined, and only depending on the window can be seen, that is, even if the window is not displayed in the display area, the window is in the working state, and the content is still output to the outside, and only the window is not seen by the person in front of the screen.
For a terminal, the display content of the window is processed by the display card and then sent to the display for display, that is, the terminal has a transmission path, and if the content is directly obtained from the path, what state the window is in is not important any more.
It should be understood that, in the existing implementation, one terminal generally provides one picture information, which can be understood as that one terminal can only provide one signal, and when more signals are needed, the number of terminals is increased.
Therefore, as a specific embodiment of the data transmission method provided by the application, please refer to fig. 8, the number of the first selection information is increased, each of the first selection information points to a different window information, and for each of the window information pointed by the first selection information, the corresponding continuous network flow information is generated, so that for one terminal, a plurality of display contents can be provided at the same time.
Specifically, after the number of the first selection information is increased, for one terminal, a plurality of signals can be provided at the same time, and because a network transmission mode is adopted, multiple signals can be transmitted within an allowable range of a transmission bandwidth without being limited by the fact that only one signal can be transmitted through a data line (a VGA line, an HDMI line, a DP line, or the like).
Further, for the window information to which the first selection information points, the state may be any one of a display state, a hidden state, an occlusion state, or a partial occlusion state, and the content of the window information is already stated in the text, and is not described herein again.
In a possible use environment, for a terminal, ten windows may exist in a display area of the terminal at the same time, and for the ten windows, ten pieces of network flow information may be output at the same time.
The plurality of windows displayed on the terminal are also in various states, and the generation of the network flow information can be completed as long as the windows exist, and the windows are not necessarily displayed in the display area.
In a possible implementation manner, for a plurality of generated network flow information, one allocation software may be added, for example, the number of generated network flow information is nine, and the nine network flow information may be allocated to nine large screens or one display area on one large screen or several different display areas on different screens.
Referring to fig. 9, as a specific embodiment of the data transmission method, the following steps are added:
s201, generating a plurality of option information according to the network flow information;
s202, second selection information is obtained, and the second selection information points to option information; and
s203, sending out the network flow information corresponding to the option information.
The contents of steps S201 to S203 are that the generated plurality of network flow information are selectively output, and for example, the plurality of network flow information that can be output can be controlled in a selected manner.
Specifically, in step S201, a plurality of option information is generated according to the generated network flow information, and these option information may be located in an independent display area, for example, the number of the generated network flow information is nine, and the number of the corresponding option information is also nine, which are in one-to-one correspondence and associated.
In step S202, a second selection information is obtained, where the second selection information points to one of the option information, which may be one of the nine option information appearing in step S201.
Next, in step S203, the network flow information corresponding to the option information selected in step S202 is sent out, so that the selective output of the network flow information is realized, and it is possible for the operator to directly select the corresponding option information to output which option information is desired to be output.
For example, in a certain display area, the display area is in a display state when the network flow information is output, and is in a non-display state when the output is stopped.
For another example, for a certain display area that needs to be switched to display, switching of display contents may be implemented by changing the output network stream information.
It should be understood that when a second selection message is obtained, the network flow message corresponding to the selection message is in the output state, and then when a second selection message is obtained again, the network flow message corresponding to the selection message may also be adjusted to the output stop state.
Referring to fig. 10, as a specific embodiment of the data transmission method, the following steps are added:
s501, acquiring one or more pieces of display area information, wherein each piece of display area information comprises one or more pieces of sub-display area information;
s502, third selection information is obtained, and the third selection information points to information of one sub-display area; and
s503, sending the network flow information corresponding to the second selection information to the display area information pointed by the third selection information;
wherein, the source of the display area information is one or more.
The content in steps S501 to S503 is to transmit the generated network flow information to any display area to be displayed, so that the network flow information can be directionally transmitted.
Specifically, in step S501, one or more pieces of display area information are obtained, each piece of display area information includes one or more pieces of sub-display area information, and the source of the display area information may be one or more.
The content in step S502 is to obtain third selection information, where the third selection information points to one piece of sub-display area information, and the sub-display area information may point to any piece of sub-display area information obtained in step S501.
Next, in step S503, the network flow information corresponding to the second selection information is sent to the display area information pointed by the third selection information, so that the generated network flow information is directionally transmitted, and the generated network flow can be sent to the display area on any screen connected to the terminal.
