In the embodiment of the invention, the display terminal mainboard control module carries the HDMI input interface, so that the emergency broadcasting system module carrying the HDMI output interface can be connected through the HDMI input interface. Therefore, when the emergency broadcast system module receives the emergency broadcast radio frequency signaling, the level of a preset pin in the high-definition multimedia HDMI output interface can be inverted, the emergency broadcast radio frequency signaling is analyzed, the emergency broadcast signal is output through the high-definition multimedia HDMI output interface after being obtained, the display terminal mainboard control module can play the emergency broadcast signal input by the high-definition multimedia HDMI input interface when the level of the preset pin of the HDMI input interface is determined to be changed, and therefore the emergency broadcast is carried out in the display terminal.
It can be seen that, in the embodiment of the present invention, the system for performing emergency broadcasting in the display terminal may include: the display terminal comprises a display terminal mainboard control module carrying a high-definition multimedia HDMI input interface and an emergency broadcasting system module carrying a high-definition multimedia HDMI output interface, wherein the HDMI input interface is connected with the HDMI output interface in a matching mode.
Generally, the display terminal motherboard control module may be configured with one, two, or more High Definition Multimedia Interface (HDMI) input interfaces, and in the embodiment of the present invention, one of the HDMI input interfaces may be used to be connected in a matching manner with the emergency broadcast system module carrying the HDMI output Interface. The emergency broadcasting system module can be inserted into the display terminal, namely, the display terminal is connected with the HDMI output interface in a matching mode through the HDMI input interface, and the emergency broadcasting system module is inserted into the display terminal mainboard control module, so that the system for performing emergency broadcasting is the display terminal. Or, the emergency broadcasting system module can be located outside the display terminal, that is, the HDMI input interface on the display terminal main board control module is connected with the HDMI output interface on the emergency broadcasting system module in a matching manner through an HDMI connecting cable, so that the display terminal main board control module is connected with the emergency broadcasting system module.
Fig. 1 is an architecture diagram illustrating an emergency broadcasting system in a display terminal according to an exemplary embodiment. As shown in fig. 1, the emergency broadcasting system in a display terminal includes: a display terminal mainboard control module 100 carrying a high-definition multimedia HDMI input interface 101, and an emergency broadcast system module 200 carrying a high-definition multimedia HDMI output interface 201. The HDMI input interface 101 may be directly connected to the HDMI output interface 201 in a matching manner, or may be connected via an HDMI cable. Here, the system further includes an HDMI cable 300, so that the HDMI cable 300 has one end connected to the HDMI input interface 101 and the other end connectable to the HDMI output interface 201, which enables a matching connection of the HDMI input interface 101 to the HDMI output interface 201.
The emergency broadcasting system module 200 has an emergency broadcasting function, and therefore, the emergency broadcasting system module 200 is configured to perform negation processing on a level of a preset pin in the high-definition multimedia HDMI output interface 201 when receiving an emergency broadcasting radio frequency signaling, and analyze the emergency broadcasting radio frequency signaling to obtain an emergency broadcasting signal and output the emergency broadcasting signal through the high-definition multimedia HDMI output interface 201.
The display terminal motherboard control module 100 may be configured to play the emergency broadcast signal input by the high-definition multimedia HDMI input interface 101 when it is determined that the level of the preset pin of the high-definition multimedia HDMI input interface 101 changes.
The emergency broadcast system module 200 may receive a radio frequency signal, wherein the radio frequency signal may include: analog frequency modulation PAL DK signals, terrestrial digital television DTMB signals, cable digital television DVBC signals, satellite digital television DVBS signals, direct broadcast satellite digital television ABS-S signals and the like, which can be received 200 by the emergency broadcast system module, and when the radio frequency signals received 200 by the emergency broadcast system module contain emergency broadcast radio frequency signaling, the level of a preset pin in the HDMI output interface 201 can be inverted, and the emergency broadcast radio frequency signaling is analyzed, so that the emergency broadcast signals are output through the HDMI high-definition multimedia output interface 201.
Because the HDMI input interface 101 is connected to the HDMI output interface 201 in a matching manner, after the level of the preset pin in the HDMI output interface 201 is inverted, the level of the preset pin of the corresponding HDMI input interface 101 changes, and thus the display terminal main board control module 100 can determine the level change of the preset pin of the HDMI input 101 interface, so that the emergency broadcast signal input by the high-definition multimedia HDMI input interface 101 can be directly played.
In another embodiment of the present invention, in order to reduce the power consumption, the display terminal motherboard control module or the emergency broadcasting system module may be in a standby operating mode, so that the emergency broadcasting system module is further configured to perform a wake-up process when it is determined that the display terminal motherboard control module or the emergency broadcasting system module is in the standby operating mode before performing an inverting process on the level of the preset pin in the HDMI output interface. And the display terminal mainboard control module is also used for performing awakening processing when the display terminal mainboard control module is determined to be in a standby working mode before the display terminal mainboard control module is used for playing the emergency broadcast signal input by the high-definition multimedia HDMI input interface.
Thus, in the system for performing emergency broadcasting in the display terminal of this embodiment, the display terminal motherboard control module can be connected to the emergency broadcasting system module carrying the HDMI output interface through the HDMI input interface without hardware modification, so that when the emergency broadcasting system module receives the emergency broadcasting radio frequency signaling, the level of the preset pin in the HDMI output interface can be inverted, and the emergency broadcasting radio frequency signaling is analyzed to obtain the emergency broadcasting signal and then output through the HDMI output interface, and the display terminal motherboard control module can play the emergency broadcasting signal input by the HDMI input interface when determining the level change of the preset pin of the HDMI input interface, thereby implementing emergency broadcasting in the display terminal, and thus, the display terminal does not need to replace the existing main control module carrying the HDMI input interface, the function of emergency broadcasting can be realized, and the functions of the display terminal are expanded, and the resources are further saved.
In the embodiment of the present invention, the emergency broadcast system module needs to carry an HDMI output interface, so that when receiving the emergency broadcast radio frequency signaling, the emergency broadcast system module can perform corresponding operations and output the emergency broadcast radio frequency signaling through the HDMI output interface.
Fig. 2 is a flowchart illustrating a method of emergency broadcasting in a display terminal according to an exemplary embodiment. The method is applied to an emergency broadcasting system module carrying an HDMI output interface in the system, and as shown in fig. 2, the process of performing emergency broadcasting in the display terminal may include:
step 201: and when the emergency broadcast radio frequency signaling is received, performing inversion processing on the level of a preset pin in the HDMI output interface.
The method can receive the radio frequency signal, and when the received radio frequency signal is determined to contain the emergency broadcast radio frequency signaling, the level of a preset pin in the HDMI output interface can be directly inverted. For example: if the current level of the preset pin in the HDMI output interface is "0", the processed level is "1" after performing the negation process, and vice versa.
Step 202: and analyzing the emergency broadcast radio frequency signaling to obtain an emergency broadcast signal, and outputting the emergency broadcast signal through a high-definition multimedia HDMI output interface.
The emergency broadcast rf signaling is further analyzed to obtain an emergency broadcast signal, which is a multimedia signal, such as: one or more of a sound signal, a video signal, etc.
Because the HDMI output interface of emergency broadcast system module and the HDMI input interface of display terminal mainboard control module are connected in a matching manner, after the level of the preset pin in the HDMI output interface is inverted, the preset pin in the corresponding HDMI input interface can send the level change, namely, the display terminal mainboard control module can determine the level change of the preset pin of the high-definition multimedia HDMI input interface, and therefore, the emergency broadcast signal input by the high-definition multimedia HDMI input interface can be played.
Therefore, in the embodiment of the invention, the emergency broadcast system module has the functions of receiving the radio frequency signal and analyzing the radio frequency signal, and can also perform negation processing on the level of the preset pin in the HDMI output interface and output the analyzed emergency broadcast signal through the HDMI output interface, so that the display terminal mainboard can control the emergency broadcast signal to be played, and the emergency broadcast in the display terminal is realized.
Certainly, when the emergency broadcast system module is in the standby operating mode, the emergency broadcast system module needs to be awakened before performing the negation processing on the level of the preset pin in the high-definition multimedia HDMI output interface. That is, in another embodiment of the present invention, before performing the inverting process on the level of the preset pin in the HDMI output interface, the method further includes: and when the standby working mode is determined, performing awakening processing. Therefore, the emergency broadcast system module does not need to be in a working state all the time, can receive the radio frequency signals in a standby mode, can be awakened once receiving the emergency broadcast radio frequency signaling, can carry out the working state, and then carries out subsequent corresponding negation processing, analysis processing and the like. Thus, the resource consumption can be greatly saved.
Generally, one, two or more HDMI input interfaces are carried on the display terminal motherboard control module, that is, in the embodiment of the present invention, the display terminal motherboard control module carrying the HDMI input interfaces does not need to perform hardware modification, and after the HDMI input interfaces are connected in a matching manner with the HDMI output interfaces of the emergency broadcast system module, emergency broadcast on the display terminal can be implemented.
Fig. 3 is a flowchart illustrating a method of emergency broadcasting in a display terminal according to an exemplary embodiment. The method is applied to a display terminal mainboard control module carrying an HDMI input interface in the system, and as shown in fig. 3, the process of performing emergency broadcasting in the display terminal may include:
step 301: and detecting the level of a preset pin of the high-definition multimedia HDMI input interface.
The level of a preset pin of the HDMI input interface can be monitored.
Step 301: and when the level change of the preset pin of the high-definition multimedia HDMI input interface is determined, playing the emergency broadcast signal input by the high-definition multimedia HDMI input interface.
When the emergency broadcast system module receives the emergency broadcast radio frequency signaling, the level of a preset pin in the high-definition multimedia HDMI output interface can be inverted, the emergency broadcast radio frequency signaling is analyzed, and the emergency broadcast signal is output through the high-definition multimedia HDMI output interface. Because the HDMI output interface of the emergency broadcasting system module is connected with the HDMI input interface of the display terminal mainboard control module in a matching manner, after the level of the preset pin in the HDMI output interface is inverted, the level change of the preset pin of the HDMI input interface can be determined, and an emergency broadcasting signal input by the high-definition multimedia HDMI input interface can be played. That is, in this embodiment, the level change is caused by inverting the level of the preset pin when the emergency broadcast system module carrying the high-definition multimedia HDMI output interface connected to the high-definition multimedia HDMI input interface in the system receives the emergency broadcast radio frequency signaling, and the emergency broadcast signal is output through the high-definition multimedia HDMI output interface after the emergency broadcast system module receives the emergency broadcast radio frequency signaling and analyzes the emergency broadcast radio frequency signaling.
Therefore, in the embodiment, the display terminal does not need to replace the existing main board control module carrying the HDMI input interface, and after the HDMI input interface is connected with the HDMI output interface of the emergency broadcast system module in a matching manner, emergency broadcast on the display terminal can be realized, so that not only are the functions of the display terminal expanded, but also resources are further saved.
Similarly, when the display terminal motherboard control module is in the standby operating mode, the display terminal motherboard control module needs to be awakened before the emergency broadcast signal is played. That is, in another embodiment of the present invention, before playing the emergency broadcast signal input by the HDMI input interface, the method further includes: and when the standby working mode is determined, performing awakening processing. Therefore, the display terminal mainboard control module does not need to be in a working state all the time, and the working state can be carried out only when the level change of the preset pin of the HDMI input interface is determined, so that the consumption of resources can be greatly reduced.
The following operational flows are integrated into the specific embodiments to illustrate the control method provided by the embodiments of the present invention.

step 501: is the emergency broadcast system module 200 determined whether emergency broadcast radio frequency signaling is received? If yes, go to step 502, otherwise, go back to step 501.
Step 502: is the emergency broadcast system module 200 determine whether the current operating mode is the standby operating mode? If yes, go to step 503, otherwise, go to step 504.
Step 503: the emergency broadcast system module 200 performs a wakeup process and proceeds to step 504.
Step 504: the emergency broadcast system module 200 inverts the pin14 in the HDMI output interface 201.
Step 505: the emergency broadcast system module 200 analyzes the emergency broadcast radio frequency signaling to obtain an emergency broadcast signal, and then outputs the emergency broadcast signal through the HDMI output interface 201.
Wherein, step 504 and step 505 can be performed synchronously.
Step 506: the display terminal motherboard control module 100 determines whether the level of pin14 in the HDMI input interface 101 changes? If yes, go to step 507, otherwise, go back to step 506.
Step 507: display terminal motherboard control module 100 determines whether the current operating mode is the standby operating mode? If yes, go to step 508, otherwise go to step 509.
Step 508: the display terminal motherboard control module 100 performs wakeup processing. And proceeds to step 509.
Step 509: the display terminal main board control module 100 plays the emergency broadcast signal input by the high-definition multimedia HDMI input interface 101.
Therefore, the display terminal mainboard control module carries the HDMI input interface, and thus, the emergency broadcasting system module carrying the HDMI output interface can be connected through the HDMI input interface. Therefore, when the emergency broadcast system module receives the emergency broadcast radio frequency signaling, the level of a preset pin in the high-definition multimedia HDMI output interface can be inverted, the emergency broadcast radio frequency signaling is analyzed, the emergency broadcast signal is output through the high-definition multimedia HDMI output interface after being obtained, the display terminal mainboard control module can play the emergency broadcast signal input by the high-definition multimedia HDMI input interface when the level of the preset pin of the HDMI input interface is determined to be changed, and therefore the emergency broadcast is carried out in the display terminal. In addition, the display terminal mainboard control module and the emergency broadcasting system module can carry out emergency broadcasting in any working mode, and the effectiveness and the stability of the emergency broadcasting are ensured.
