In the following embodiments of the present application, a signal source display method applied to the application architecture shown in fig. 3 is taken as an example for schematic explanation.
Based on the foregoing embodiment, a signal source display method in the embodiment of the present application is described below, and referring to fig. 4, which is a flowchart of a signal source display method in the embodiment of the present application, and the method includes:
step 400: in response to an operation of exhibiting the plurality of signal sources, it is detected whether there is a signal input of the signal source.
In this embodiment of the present application, a signal source tag may be set on a terminal device, so as to display the content of each signal source, and only when it is detected that a signal is input to the signal source, the signal source is displayed, which may facilitate user preview, and the signal source without signal input is not displayed, and may simplify interface display, and reduce unnecessary operations and resource waste, so that it is necessary to detect whether a signal is input to the signal source, specifically, when step 400 is executed, two ways are provided in this embodiment of the present application:
the first mode is as follows: and (4) active detection.
Detecting whether a signal of a signal source is input, comprising: and detecting whether a signal of the signal source is input or not in response to a switching operation for the set signal source tag.
Of course, switching to the signal source label includes directly selecting the signal source label after power-on, and also includes switching back to the signal source label from the full screen mode.
Specifically, the method comprises the following steps: judging whether the signal source event of each signal source is updated or not, judging the state type of the signal source event, if the state type of the signal source event is determined to be access (in), determining that a signal is input, and if the state type of the signal source event is determined to be pull-out (out), determining that no signal is input.
The signal source events can be stored in a signal source control module in the terminal device, each signal source has a corresponding signal source event and a state type of the signal source event, so that each signal source can be monitored, and further, when the signal source is actively detected after being switched to a signal source label, a new signal source event of the new signal source can be registered.
That is to say, in the embodiment of the present application, when the user switches to the signal source tag, it is actively detected whether each signal source has signal input in sequence, so that resource waste of polling detection signal sources each time can be reduced.
The second mode is as follows: passive event reception detection.
Detecting whether a signal of a signal source is input, comprising: when the signal source change signal is detected, the access state of the hardware interface corresponding to the signal source is detected according to the signal source change signal, if the access state of the corresponding hardware interface is determined to be the power-on state, signal input of the signal source is determined, and if the access state of the corresponding hardware interface is determined to be the power-off state, no signal input of the corresponding signal source is determined.
In the embodiment of the application, each signal source can be accessed through a hardware interface on the terminal device, when a signal source is accessed or pulled out, a hardware module of the hardware interface can generate an interrupt signal, namely a signal source change signal, after the signal source control module receives the signal source change signal, the power-on or power-off state of the corresponding hardware interface can be read, if the power-on state is determined, the signal input of the signal source corresponding to the hardware interface is determined, if the power-off state is determined, the signal source corresponding to the hardware interface is pulled out, no signal input exists, further, the signal source control module can record the state type of the signal source event of the corresponding signal source in a memory according to the judgment result of the hardware interface, and send a notification to an upper layer to inform that the state type of the signal source event has changed.
That is to say, when the access state of the signal source changes, a signal source change signal can be sent out, the signal source change signal at least carries a signal source identifier, for example, the number of paths of the signal source, and then when the signal source change signal is received, whether the signal source has a signal input or not can be detected.
Step 410: if the signal input of the multi-channel signal source is determined, the playing windows corresponding to the signal sources with the signal input are respectively established on the display interface, and the content data of the signal sources are respectively obtained.
When step 410 is executed, the method specifically includes:
and S1, if the signal input of the multi-channel signal source is determined, respectively establishing a playing window corresponding to each signal source with the signal input on the display interface.
Specifically, according to the number of signal sources with signal input, and according to the corresponding arrangement mode, the playing windows corresponding to the signal sources are respectively established on the display interface.
For example, if 3 signal sources are detected to have signal inputs, for example, signal source 1, signal source 2, and signal source 3, respectively, then 3 playing windows may be established on the display interface, for example, as shown in fig. 5, which is a schematic diagram of an arrangement manner of the playing windows in the embodiment of the present application, as shown in fig. 5, the display interface may be divided into 3 parts, which are divided into left and right equally, and then the left area is divided into upper and lower equally, and each area corresponds to one playing window and one signal source respectively.
Of course, the arrangement of the playing windows is not limited in the embodiments of the present application, and may be set according to the number and the actual situation.
And S2, respectively acquiring the content data of each signal source.
The content data is streaming media data, and the streaming media data at least comprises video data.
Specifically, the method comprises the following steps: respectively acquiring a playing path of each signal source, wherein the playing path at least comprises a signal source identifier, a local streaming media server address and a local video signal source; and respectively acquiring the content data of each signal source according to the playing path of each signal source.
In the embodiment of the application, a play path is generated for each signal source, and real-time streaming media data, that is, content data, can be acquired through the play path.
For example, the playback path is rtsp://127.0.0.1/video _ signal _ source/(num)
Wherein, 127.0.0.1: representing the local streaming server address, is fixed for the same signal source. video _ signal _ source: representing a local video source, is also fixed for the same source. num: for signal source identification, which signal source is indicated, the value is a number, for example: 1. 2 and 3.
Further, in the embodiment of the present application, if it is determined that only one signal source has a signal input, only the content of the signal source of the one path may be displayed on the display interface, at this time, the content may be displayed in a full screen, and if it is determined that no signal source has a signal input, the content of any signal source may not be displayed, at this time, for example, prompt information may be displayed, for example, a user is prompted that no signal source is currently accessed, and no limitation is performed.
Step 420: and respectively displaying the content data of the corresponding signal source in each playing window.
Further, in this embodiment of the present application, it is further required to obtain configuration information of the terminal device, and determine a configuration level of the terminal device, and specifically, a possible implementation manner is provided, before content data of a corresponding signal source is displayed in each playing window, the method further includes: acquiring configuration information of terminal equipment, wherein the configuration information at least comprises the core number of a Central Processing Unit (CPU) and the size of a memory; and judging whether the video playing configuration condition is met or not according to the CPU core number and the memory size.
The video playing configuration condition represents a condition capable of supporting simultaneous display of multiple channels of videos, the terminal equipment can be considered to be in high configuration when the video playing configuration condition is met, and the terminal equipment can be considered to be in low configuration when the video playing configuration condition is not met.
For example, if the number of the CPU cores is not greater than 2, it is determined that the video playing configuration condition is not met, and the configuration is low; if the number of the CPU cores is more than 2 cores and the size of the memory is not more than 1G, determining the configuration is low; and if the number of the CPU cores is more than 2 cores and the size of the memory is more than 1G, determining that the configuration condition of video playing is met, and determining that the configuration condition is high configuration.
The number threshold setting of the number of the CPU cores and the memory threshold setting of the memory size are not limited to 2 cores and 1G, and may be set according to an actual situation, and the setting of the video playing configuration condition is not limited to the number of the CPU cores and the memory size, and may also be set according to an actual situation, which is not limited in the embodiment of the present application.
Then, according to whether the terminal device meets the video playing configuration condition, executing step 420 accordingly includes: and respectively displaying the content data of the corresponding signal source in each playing window according to the configuration information.
Specifically, the following two cases can be classified:
in the first case: and if the configuration information of the terminal equipment conforms to the video playing configuration conditions, respectively displaying the video content of the corresponding signal source in each playing window, wherein the content data is streaming media data, and the streaming media data at least comprises video data.
For a highly configured terminal device, the displayed content data is video content, and a user can view real-time dynamic video content.
In the second case: and if the configuration information of the terminal equipment does not accord with the video playing configuration conditions, respectively extracting pictures in the video data of each signal source and displaying the pictures in each corresponding playing window.
In the embodiment of the application, considering that a low-configuration terminal device may not support simultaneous display of multiple videos, in order that a user can quickly know what the content of each signal source is, a static picture of each signal source can be displayed and displayed in a picture mode.
In addition, in order to improve user experience and facilitate a user to better understand content of a signal source, a displayed static picture may be continuously updated when the picture is displayed, and in particular, a possible implementation manner is provided in the embodiment of the present application, in which pictures in video data of each signal source are respectively extracted and the pictures are displayed in corresponding play windows, and the method specifically includes: and respectively extracting the content of a frame of picture in the video data of each signal source according to a set time interval, and displaying the picture in each corresponding playing window according to the currently extracted picture content.
For example, a frame may be extracted from the video data at intervals, for example, 10 seconds, and a picture may be generated using a bitmap file (bitmap) object and displayed in a corresponding playing window.
Further, for the convenience of viewing by the user, when the content data of the corresponding signal source is respectively displayed in each playing window, the method may further include: and respectively displaying the names of the corresponding signal sources in each playing window. Therefore, the user can not only view the content of each signal source on the display interface, but also know which signal source corresponds to the content.
And then, on a display interface, responding to the selection operation aiming at any playing window, switching to a full screen mode, and displaying the video content of the signal source corresponding to any playing window in the full screen mode.
Therefore, in the embodiment of the application, the contents of a plurality of signal sources can be displayed on the display interface simultaneously, a user can move a focus through a remote controller to select the content which the user wants to see, when the user clicks and selects a signal source of a certain playing window, the full-screen mode can be switched, the video content of the signal source corresponding to the playing window is displayed, at this time, even if the previous displayed static picture is, the real-time video content can be displayed in the full-screen mode, and then, if the user wants to reselect the signal source, the user can return to a signal source label page or a home page through a return key or a home page key of the remote controller, so that the signal.
Further, when content data of a corresponding signal source is displayed in each playing window on the display interface, it may be further determined whether a signal source change signal is detected continuously, that is, a passive event reception detection manner in the foregoing embodiment, and if a signal source change signal is detected and according to the signal source change signal, if it is determined that an access state of a corresponding hardware interface is a power-down state, it is determined that the corresponding signal source has no signal input, at this time, a possible implementation manner is further provided in this embodiment of the present application, which further includes: and if the corresponding signal source is determined to have the playing window on the display interface, canceling the playing window of the corresponding signal source.
That is to say, in the embodiment of the present application, if it is detected that a signal source is pulled out and no signal is input, the previously established play window may be cancelled, and the signal source does not need to be displayed on the display interface.
In the embodiment of the application, whether the signal input of the signal source exists is detected in response to the operation of displaying the multi-channel signal source, if the signal input of the multi-channel signal source is determined, the playing windows corresponding to the signal sources with the signal input are respectively established on the display interface, the content data of the signal sources are respectively acquired, and the content data of the corresponding signal sources are respectively displayed on the playing windows according to the configuration information of the terminal equipment, so that the contents of different signal sources are played on a plurality of playing windows of the same display interface, a plurality of signal sources are simultaneously displayed on one display interface, and only the signal source with the signal input is displayed through the signal source detection, thereby avoiding the resource waste, determining the display mode of each signal source according to the configuration information of the terminal equipment during the display, being video content or static pictures, being applicable to the terminal equipment with different configurations, the user can easily check the content of each signal source, so that the required signal source content can be quickly selected without switching and checking one by one, the time consumption is reduced, the efficiency is improved, and the user experience is also enhanced.

Based on the same inventive concept, a specific application scenario is further described below, taking a terminal device as a television, the terminal device adopting an Android system, the terminal device at least including a signal source display module, a streaming media service, a signal source control module and a hardware interface module as an example, an interaction flow among the modules when the terminal device executes the signal source display method in the embodiment of the present application is described, and specifically referring to fig. 7, another signal source display method flow chart in the embodiment of the present application is shown.
Step 700: the signal source presentation module registers a signal source event with the streaming media service.
For example, in the Android system, a signal source presentation (SignalView) module of a user layer performs active detection when switching to a signal source tag, and registers a new signal source event, where a streaming media service (SignalMediaService) is located in a frame layer of the Android system, for example.
Step 701: the signal source display module sends an instruction for detecting whether the signal source has signal input to the streaming media service.
Step 702: the streaming media service forwards an instruction for detecting whether the signal source has signal input to the signal source control module.
Step 703: and the signal source control module returns a signal source detection result to the streaming media service.
The signal source control (SignalControlDriver) module is located in an inner core of an Android system, and is mainly used for determining an access state of a hardware interface of each signal source and recording a state type of a signal source event of each signal source according to the access state of the hardware interface.
Therefore, the signal source control module can send an event notice to the upper layer according to the current state type of each signal source event recorded in the memory, and inform each signal source of the detection result and whether a signal source with a signal input exists.
Step 704: the streaming service sends a broadcast notification.
That is, after receiving the signal source detection result of the signal source control module, the streaming media service sends the signal in a broadcast mode to inform which signal source has signal input.
The broadcast notification at least includes a signal source identifier of a signal source for signal input to identify which signal source has signal input, for example, in an Android system, an Intent tool may be used to transmit the signal source identifier.
And at this time, after receiving the signal source detection result, the streaming media service knows which signal source has signal input, and generates a streaming media playing path for the signal source having signal input, so that the upper layer can obtain real-time video data through the playing path, and the video content can be displayed on the display interface of the signal source label in real time in the user layer similar to the playing of network video.
Step 705: the signal source display module displays the content data.
Specifically, if the video playing configuration condition is met, that is, the high configuration is performed, the video content of each signal source is displayed, and if the video playing configuration condition is not met, that is, the low configuration is performed, the picture displaying each signal source is continuously updated.
The steps 700 to 705 are mainly directed to an active detection mode, when a signal source label is switched, whether a signal of a signal source is input is detected once, whether a signal source event in a signal source control module is updated is judged, whether a state type is accessed or pulled out is judged, and then the signal source with the signal input is determined and displayed.
Step 706: the hardware interface module sends a signal source change signal to the signal source control module.
In the embodiment of the application, when a signal source is connected or pulled out, the hardware interface module of the signal source can generate an interrupt signal, namely a signal source change signal, and the interrupt signal is sent to the signal source control module through the driving program.
Step 707: and the signal source control module informs the streaming media service of the signal source detection result.
Specifically, after receiving a signal source change signal, the signal source control module reads the power-on or power-off state of the corresponding hardware interface, determines that a signal input exists in the signal source corresponding to the hardware interface if the power-on state is the power-on state, determines that no signal input exists in the corresponding signal source if the power-off state is the power-off state, further sends the determined signal source detection result to the streaming media service, and updates the state type of the signal source event recorded in the memory.
Step 708: the streaming service sends a broadcast notification.
Step 709: the signal source display module displays the content data.
The execution manner of step 708 and step 709 is similar to that of step 704 and step 705, and is not described here again.
In steps 706-709, mainly for the passive event receiving and detecting manner, when a signal is plugged in or pulled out, the hardware interface module generates an interrupt signal, and sends the interrupt signal to the signal source control module through the driver, and further notifies the signal source display module that there is a signal input of the signal source or a signal interrupt of the signal source, and the signal source display module performs display.
It should be noted that, the execution order of each step in the embodiment of the present application is not limited, and this is only one possible example.
In step 705 or step 709, when the content data is displayed, a signal source identifier, for example, the number of paths of the signal source, is obtained from the Intent tool, and a corresponding play path is generated, a corresponding play window is newly created on the display interface, the play window corresponds to a player, and the play path is transmitted, so that the content data of the signal source can be displayed, specifically referring to fig. 8, which is a flowchart for displaying the content data of the signal source in the embodiment of the present application.
Step 800: a player is created.
Each playing window corresponds to a player, for example, a video player.
Step 801: and starting playing.
Step 802: and acquiring a play path.
Step 803: and collecting video data of the signal sources corresponding to the paths.
Step 804: returning the video data to the player.
And then the content data of each signal source can be played, if the terminal equipment accords with the video playing configuration condition, the video content is displayed, and if the terminal equipment does not accord with the low video playing configuration condition, one frame is extracted from the video data at intervals, a corresponding picture is generated, and the picture is displayed.
