Detailed Description
A detailed description will be given below of a specific implementation of a display apparatus and a display method thereof according to an embodiment of the present invention with reference to the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all 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.
Before describing the display method of the display device, first, a display device is described, the structure of which is shown in fig. 1, and the display interface of the display screen corresponding to fig. 1 is shown in fig. 2, the display device may include N data channels 10, and the display device may further include M display interfaces 20 located in the same display screen, where M is an integer greater than N;
in fig. 1, N is 3 and M is 4, but in actual cases, the values of M and N are not limited to 4 and 3, and may be other values set according to actual cases, and are not limited herein, and only the structure shown in fig. 1 is described here as an example.
Also, as shown in fig. 1, the display apparatus further includes: the demultiplexing unit 30 and the player 40 are disposed between the data channel 10 and the display interface 20, where the demultiplexing unit 30 has a storage space, and can temporarily store the data to be displayed transmitted through the data channel 10 in the storage space, wait for the demultiplexing unit 30 to decode the stored data to be displayed, and then the demultiplexing unit 30 transmits the decoded data to be displayed to the player 40 and then to the display interface 20, so as to implement multi-screen display.
To illustrate, in order to ensure that each display interface 20 can normally display images and avoid mutual interference between the display interfaces 20, the demultiplexing unit 30, the player 40, the display interfaces 20, and each path of data to be displayed are arranged in a one-to-one correspondence manner.
Of course, in practical cases, the display device further includes other structures for implementing the display function, which can be referred to in the prior art and will not be described in detail herein.
Specifically, an embodiment of the present invention provides a display method of a display device, and as shown in fig. 3, the display method includes:
s301, acquiring M paths of data to be displayed, which are currently used for respectively displaying on M display interfaces;
the data to be displayed on one display interface corresponds to one path of data to be displayed, and the number of the paths of the data to be displayed can be understood as the number of the display interfaces.
Therefore, when the contents displayed on different display interfaces are different, different data to be displayed need to be provided for each display interface, so that the number of paths of the provided data to be displayed needs to be the same as the number of the display interfaces, and each path of data to be displayed is used for displaying on the corresponding display interface.
The data to be displayed may be transmitted by a Transport Stream (TS) method, or may be transmitted by other methods, which is not limited herein.
S302, transmitting each path of data to be displayed through each data channel according to the idle state of each data channel; the data to be displayed in the middle part of the branch is transmitted through the same data channel;
and S303, respectively displaying on each display interface according to each path of data to be displayed transmitted by each data channel.
In the embodiment of the invention, although the number of the data channels is less than that of the display interfaces, that is, the number of the data channels is less than that of the paths required to transmit the data to be displayed, M paths of data to be displayed can be transmitted through the N data channels, so that the M paths of data to be displayed are respectively displayed on the M display interfaces, and thus, on the basis of not changing the structure of the display equipment and reducing the manufacturing cost of the display equipment, the multi-screen display of the display equipment can be realized, and the experience and the feeling of a user are improved.
In a specific implementation, in the embodiment of the present invention, transmitting each path of data to be displayed through each data channel according to the idle state of each data channel specifically includes:
determining a first channel for transmitting K paths of data to be displayed according to a preset channel determination rule; k is a positive integer smaller than M, and each of the rest data channels except the first channel in the N data channels is a second channel;
determining K paths of data to be displayed transmitted through a first channel according to a preset data transmission rule;
sequentially transmitting K paths of data to be displayed according to the idle state of the first channel;
and respectively transmitting the other paths of data to be displayed through the second channels.
For example, taking the structure shown in fig. 1 as an example, when M is 4 and N is 3, K may be 2, that is, there are 2 channels of data to be displayed that share one data channel, and the shared data channel is defined as a first channel; if it is determined that the Data to be displayed 1 and the Data to be displayed 4 share one Data channel, and the Data channel is P1, that is, the first channel is P1, then:
the first channel P1 may sequentially transmit Data to be displayed 1 and Data to be displayed 4 according to the idle state;
the Data channel P2 transmits Data2 to be displayed;
the Data channel P3 transmits Data3 to be displayed.
Therefore, transmission of each path of data to be displayed can be achieved through fewer data channels, normal display of pictures on each display interface can be guaranteed, multi-screen simultaneous display is achieved, and experience of a user is improved.
Optionally, in an embodiment of the present invention, the channel determination rule includes:
selecting any data channel from the N data channels as a first channel, wherein for at least part of acquired frame data to be displayed, the first channels corresponding to K paths of data to be displayed of different frames are the same data channel;
or, any data channel in an idle state is selected from the N data channels as the first channel.
For example, referring to the structure shown in FIG. 1, where the three data lanes are labeled P1, P2, and P3, respectively, data lane P1 may always be selected as the first lane, or data lane P2 may always be selected as the first lane, or data lane P3 may always be selected as the first lane.
That is to say, in an actual situation, when the first channel is selected, the first channel can be selected according to actual needs to meet the needs of various application scenarios, so that the flexibility of design is improved.
Therefore, the first channel can be prevented from being repeatedly determined for many times, the time for determining the first channel is reduced, the data transmission time is further reduced, the data transmission efficiency is improved, and normal display of each display interface is guaranteed.
For another example, also referring to the structure shown in fig. 1, when the first frame data corresponding to each path is acquired, one data channel is arbitrarily selected from the three data channels as the first channel, if the data channel P1 is selected as the first channel; then, determining the size of the first frame data corresponding to each path, at this time:
if the two first frame data transmitted in the data channel P1 are smaller two, then the data channel P1 is always kept as the first channel;
if the two first frame data transmitted in the data channel P1 are not smaller, one data channel may be selected from the data channels again as the first channel according to the connection relationship between the current data channel and the demultiplexing unit and the principle of the minimum adjustment degree, and the first channel is used to transmit the two to-be-displayed data with smaller data size, and the first channel is kept unchanged from the acquired second frame data.
Therefore, the first channel can be prevented from being repeatedly determined for multiple times, so that the time for determining the first channel is reduced, and meanwhile, the data to be displayed can be normally and effectively transmitted, and therefore, the normal display of each display interface can be ensured.
For another example, still referring to the structure shown in fig. 1, when four paths of Data to be displayed are respectively marked as Data1, Data2, Data3 and Data4, and three Data channels are respectively marked as P1, P2 and P3, taking Data to be displayed 4 as an example, then:
it may be determined first whether data channel P1 is in an idle state;
if yes, the Data to be displayed Data4 can be transmitted through the Data channel P1, and the Data channel P1 is the first channel;
if not, judging whether the data channel P2 is in an idle state;
if yes, the Data to be displayed Data4 can be transmitted through the Data channel P2, and the Data channel P2 is the first channel;
if not, judging whether the data channel P3 is in an idle state;
if yes, the Data to be displayed Data4 can be transmitted through the Data channel P3, and the Data channel P3 is the first channel;
if not, the Data to be displayed Data4 can be transmitted again while waiting for the Data channel P3 to be in the idle state.
Therefore, when the first channel is determined according to the idle state, the data channel in the idle state can be fully utilized to transmit the data to be displayed, so that the data to be displayed can be normally and effectively transmitted, the problem that the data to be displayed cannot be effectively transmitted when the data channel which is not in the idle state is selected is solved, the effectiveness of data transmission is improved, and the situation that pictures can be smoothly displayed on each display interface is guaranteed.
Optionally, in this embodiment of the present invention, the data transmission rule includes:
when N paths of data to be displayed are selected from the M paths of data to be displayed, determining a data channel for transmitting the N paths of data to be displayed, and determining at least part of the rest M-N paths of data to be displayed and one path of data to be displayed corresponding to the first channel as K paths of data to be displayed;
or selecting K paths of data to be displayed from the M paths of data to be displayed according to the data size of the acquired data to be displayed, and transmitting the K paths of data to be displayed through the first channel.
For example, referring to the structure shown in fig. 1, four paths of Data to be displayed are respectively marked as Data1, Data2, Data3 and Data4, three Data channels are respectively marked as P1, P2 and P3, first, it is defined that Data to be displayed 1 needs to be transmitted through Data channel P1, Data to be displayed 2 needs to be transmitted through Data channel P2, and Data to be displayed 3 needs to be transmitted through Data channel P3, then:
if the first channel is the data channel P1, the K selected channels of data to be displayed include: data to be displayed 1 and Data to be displayed 4;
if the first channel is the data channel P2, the K selected channels of data to be displayed include: data to be displayed 2 and Data to be displayed 4;
if the first channel is the data channel P3, the K selected channels of data to be displayed include: data to be displayed 3 and Data to be displayed 4.
For another example, referring to the structure shown in fig. 1, when four paths of Data to be displayed are respectively marked as Data1, Data2, Data3 and Data4, and three Data channels are respectively marked as P1, P2 and P3, if 2 paths of Data to be displayed selected from 4 paths of Data to be displayed are Data to be displayed 1 and Data to be displayed 2 according to the Data size of the four paths of Data to be displayed, then: the selected K paths of data to be displayed comprise: data to be displayed 1 and Data to be displayed 2.
Therefore, when K paths of data to be displayed are selected according to the size of the acquired data of each path of data to be displayed, the size of the data to be transmitted is considered, so that the data to be displayed can be normally and effectively transmitted, and the smooth display of the picture on each display interface is ensured.
Specifically, in the embodiment of the present invention, according to the data size of each acquired path of data to be displayed, K paths of data to be displayed are selected from M paths of data to be displayed and transmitted through a first channel, which specifically includes:
if the obtained current M paths of data to be displayed are all first frame data, K paths of data to be displayed are selected from the M paths of data to be displayed at will and transmitted through a first channel;
and if the obtained current M paths of data to be displayed are data except the first frame, selecting K paths of data to be displayed with the minimum data from the data to be displayed of each path of the first frame.
When the first frame data is acquired, the storage space in the demultiplexing unit is temporarily empty (that is, there is no data to be displayed stored in the storage space temporarily), so that the storage space has more space to store the data to be displayed, and therefore, when M channels of data to be displayed are transmitted through N data channels, K channels of data to be displayed can be arbitrarily selected from the M channels of data to be displayed and transmitted through the first channel.
After the stored data to be displayed of the first frame are decoded by each demultiplexing unit, the data size of each path of data to be displayed can be determined, then the K paths of data to be displayed with the minimum data are transmitted through the first channel, the K paths of data to be displayed can be ensured to be normally and effectively transmitted, the data to be displayed with the larger data can also be ensured to be normally and effectively transmitted, the reduction of the data transmission speed caused when the multiple paths of data to be displayed with the larger data are transmitted through the shared data channel is avoided, the problem that the played picture is blocked or stopped is further avoided, the smooth display of each display interface is ensured, and the user experience is improved.
Optionally, in the embodiment of the present invention, when determining the data size of each path of data to be displayed, the following method may be used to determine:
the data size is video length × video depth × frame rate × bit depth;
the type of the data to be displayed generally includes i frames and p frames, and the type of the data to be displayed of the first frame generally is i frames, and the data of the type includes more data information and a larger data amount, so that the video length, the video depth, the frame rate and the bit depth can be determined through i frame data.
For example, but not limited to, a display screen with a resolution of 1920 × 1080, the frame rate may be 60 frames, that is, 1 second may display 60 frames, and the bit depth may be 10 bits. For example, a display screen with a resolution of 1280 × 720 may have a frame rate of 50 frames and a bit depth of 8 bits.
To illustrate, in an actual situation, in order to determine K paths of data to be displayed with the minimum data, the determination is not limited to be performed according to the data to be displayed of each path of the first frame, and may also be performed according to the data to be displayed of each path of the second frame, the third frame, or other frames, as long as the K paths of data to be displayed with the minimum data can be determined.
Optionally, in an embodiment of the present invention, the display panel further includes: m demultiplexing units, each demultiplexing unit, each display interface and each path of data to be displayed correspond to each other, and K paths of data to be displayed are sequentially transmitted according to the idle state of the first channel, and the method specifically comprises the following steps:
sequentially executing the following processes to each path of data to be displayed in the K paths of data to be displayed:
judging whether a demultiplexing unit corresponding to any path of data to be displayed and the first channel are in a binding state;
if yes, the path of data to be displayed is transmitted to the corresponding demultiplexing unit through the first channel;
if not, continuously judging whether the first channel is in an idle state at present;
if the channel is in the display state, the first channel and the bound demultiplexing unit are unbound, then the demultiplexing unit corresponding to the channel of data to be displayed is bound with the first channel, and the channel of data to be displayed is transmitted to the corresponding demultiplexing unit through the first channel;
if not, the current state of the first channel is kept until the first channel is in an idle state.
Therefore, the data to be displayed of each path transmitted by the same data channel can be normally and effectively transmitted, the data to be displayed of each path can be accurately displayed on the corresponding display interface, the display error of each display interface can be avoided while the display interface can smoothly display the image, and the user experience is improved.
Specifically, in the embodiment of the present invention, determining whether the first channel is currently in an idle state specifically includes:
judging whether the memory space of the demultiplexing unit bound by the first channel has undecoded data to be displayed;
if the first channel exists, judging that the first channel is not in an idle state;
if not, the first channel is judged to be in an idle state.
This is due to:
if there is undecoded data to be displayed in the storage space of the demultiplexing unit (if denoted by demultiplexing unit 1) to which the first channel is bound, the following problem may exist when the binding relationship between the first channel and the demultiplexing unit 1 is released:
1. the subsequent process of extracting the data to be displayed from the storage space may be affected;
2. when the next frame of data to be displayed corresponding to the demultiplexing unit 1 is transmitted again, a data stacking situation may occur, and the display of the data to be displayed on the display interface is affected finally.
Therefore, it should be ensured as much as possible that the binding is released when there is no undecoded data to be displayed in the storage space of the bound demultiplexing units, so as to ensure smooth transmission, decoding and display of each frame of data to be displayed.
Optionally, in the embodiment of the present invention, when transmitting K consecutive frames of data to be displayed for acquired data other than the first frame, the corresponding first channel is the same data channel, or the corresponding first channel is one of the data channels determined according to the idle state of each data channel.
That is to say, no matter how many frames of data to be displayed need to be transmitted, a fixed data channel can be always selected to transmit fixed K channels of data to be displayed.
For example, but not limited to, taking the structure shown in fig. 1 as an example, regardless of the Data to be displayed of the second frame being transmitted, the Data to be displayed 1 and the Data to be displayed 4 are always selected to share the Data channel P1 for transmission, and the Data to be displayed Data2 is always selected to transmit the Data channel P2 and the Data to be displayed Data3 is always selected to transmit the Data channel P3.
Therefore, the idle state of all data channels can be prevented from being polled every time one frame of data is transmitted, the data transmission efficiency is improved, the processing time before the picture is displayed is reduced, and meanwhile, the normal display of each display interface can be ensured.
Or, no matter the data to be displayed in the second frame needs to be transmitted, the common data channel needs to be selected according to the idle state of each data channel.
For example, but not limited to, taking the structure shown in fig. 1 as an example, when Data to be displayed in the jth frame of four channels is transmitted, j is a positive integer, for the Data to be displayed 4, it is necessary to determine the idle states of the Data channel P1, the Data channel P2, and the Data channel P3 in turn, and when it is determined which Data channel is in the idle state, it is set as the first channel and transmitted through the first channel; when four paths of Data to be displayed of the j +1 th frame are transmitted, the idle state of each Data channel still needs to be determined in sequence for the Data to be displayed Data 4.
Therefore, the problem that effective transmission of data is influenced when the data needing to be transmitted in the fixed data channel selected all the time is large can be avoided, and the problem of blocking or stopping playing is avoided, so that smooth display of each display interface can be guaranteed.
