However, in an actual using process, when video data is transmitted from an HDMI (High Definition Multimedia Interface) port with WIFI to a display (or a display device), a frequency multiplication harmonic signal of an HDMI clock signal falls in a wireless frequency band of 2.4G and 5G WIFI, which interferes with transmission of normal WIFI network data to a WIFI receiving device, and data bandwidth is insufficient, so that mosaic or stuck occurs in a video playing process to affect user experience.

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.
According to the method provided by the embodiment of the invention, the conference terminal switches the communication state of the WIFI module according to a preset rule; controlling the working state of the HDMI according to the communication state of the WIFI module; wherein the communication state comprises: a transmit state and a receive state; when the WIFI module is in a sending state, controlling the HDMI to send first data to HDMI display equipment; and when the WIFI module is in a receiving state, controlling the HDMI to stop sending first data to the HDMI display device. Correspondingly, the HDMI display device with the cache module receives conference data from a conference terminal and caches the conference data in the cache module; the first data is sent by the conference terminal at intervals through the HDMI interface according to a preset rule; and playing the cached conference data.
The present invention will be described in further detail with reference to examples.
Fig. 1 is a schematic flow chart illustrating a data transmission method according to an embodiment of the present invention; as shown in fig. 1, applied to a conference terminal; the conference terminal includes: a WIFI module and an HDMI interface; the method comprises the following steps:
wherein the communication state comprises: a transmit state and a receive state;
when the WIFI module is in a sending state, controlling the HDMI to send first data to HDMI display equipment;
and when the WIFI module is in a receiving state, controlling the HDMI to stop sending first data to the HDMI display device.
Here, the sending state of the WIFI module is that conference data (such as video data, which may include images, voice, and the like) of the conference terminal itself is sent to the conference terminal of the opposite terminal through the WIFI module;
and the receiving state of the WIFI module is to receive conference data sent by the conference terminal of the opposite terminal.
The first data refers to conference data which is received and needs to be sent to the HDMI display device through the HDMI interface.
In some embodiments, the switching the communication state of the WIFI module according to the predetermined rule includes:
when the WIFI module is in a sending state, the length of time for the HDMI to send the first data is determined to exceed a first preset threshold value, and the WIFI module is switched to a receiving state.
In an actual application example, if the first preset threshold is 1.5s, and it is determined that the duration for the HDMI interface to send the first data (that is, the duration for the WIFI module to send the data) is 1.5s, it is considered that the first preset condition is satisfied, and switching may be performed.
In some embodiments, the switching the communication state of the WIFI module according to the predetermined rule includes:
and when the time length of the WIFI module for receiving the second data exceeds a second preset threshold value, the WIFI module is switched to a sending state.
In an actual application example, if the second preset threshold is 1s, it is determined that the duration of receiving the second data by the WIFI module is 1s, and then the second preset condition is considered to be met, and switching can be performed.
It should be noted that the above duration and preset threshold are only examples, and can be set to millisecond level generally, so as not to affect the conference communication effect.
The first preset threshold and the second preset threshold can be determined by the conference terminal based on the data volume of the previous period of time, or can be preset by developers, and moreover, the conference test can be performed before the formal conference, and the data volume of the WIFI module and the HDMI interface is detected in the conference test process, so that the first preset threshold and the second preset threshold are determined.
Regarding the setting of the first preset threshold and the second preset threshold, the determination is based on the following condition:
the HDMI interface supplies the duration that HDMI display device lasts the demonstration to the data bulk of HDMI display device once transmission, and it is equal when the WIFI module at conference terminal accomplishes once wireless signal receiving and dispatching.
Namely, the length of time for the HDMI interface to transmit data = the length of time for the WIFI module to transmit data;
and the duration that the data that the HDMI interface sent can continuously show = the duration that the WIFI module sent data + the duration that the WIFI module received data.
Therefore, the problem of video display blockage caused by mutual interference of the HDMI and the WIFI can be solved under the condition that display services of the HDMI display equipment are not influenced, the bandwidth of the WIFI is not reduced, and smooth video experience is brought.
In practical application, the data volume received in each period of time is stable under the condition that the network state of the conference terminal is stable, a switching time interval is predetermined in order to reduce the data volume received by the conference terminal without stopping monitoring, and the state of the WIFI module is controlled according to the determined switching time interval during application. Therefore, the calculation amount of the conference terminal can be reduced, and the switching efficiency is improved.
Based on this, in some embodiments, the method further comprises:
monitoring a network state, and determining the data transceiving capacity of the WIFI module according to the network state; the data receiving and sending capacity represents the received data volume and the sent data volume in a preset time period;
determining the data transmission capacity of the HDMI; the data sending capacity represents the data volume sent in a preset time period;
determining a switching time interval according to the data sending capability and the data receiving and sending capability;
switching the communication state of the WIFI module according to a preset rule comprises the following steps:
and switching the communication state of the WIFI module according to the switching time interval.
The switching time interval may be a first preset threshold and a second preset threshold, and the first preset threshold and the second preset threshold may be the same or different, and are determined based on actual data transceiving capacity and data sending capacity.
Specifically, according to the data sending capability and the data transceiving capability, the duration that the data volume transmitted to the HDMI display device by the HDMI interface for continuous display by the HDMI display device is equal to the duration that the WIFI module of the conference terminal completes transceiving of a wireless signal.
By the method, the HDMI display device caches the HDMI data (namely the received first data) in advance, the problem of video display blockage caused by mutual interference of HDMI and WIFI in the prior art is solved, meanwhile, the WIFI bandwidth is not reduced, and smooth video experience is brought. In addition, the Electromagnetic Interference (EMI) performance of the whole machine is also improved.
