[0050] The first aspect of the present invention discloses a wireless video data acquisition method for a video receiving terminal device, wherein the video receiving terminal device comprises a wireless video data acquisition card. Figure 1 The wireless video data acquisition card includes a WIFI communication module, a central processing module, a DSP codec module, an HDMI to TTL and HDMI module, and a TTL to USB module. Figure 2 , the wireless video data acquisition method comprises the following steps:

[0051] S100, receiving a request for establishing a WIFI connection sent by a video source terminal; in the present invention, the video source terminal includes a mobile phone and a tablet, that is, the technical solution of the present invention includes but is not limited to a scenario in which a mobile phone and a tablet are used to obtain video source data, and WIFI is used between the video source terminal and the video receiving terminal device for data transmission, and the WIFI standard used may be WIFI4, WIFI5 and WIFI6;

[0052] S200, establishing a WIFI connection with the video source terminal in response to the WIFI connection request; in the present invention, before the video source terminal establishes a WIFI connection with the video receiving terminal device, multiple other video source terminals may have established WIFI connections with the video receiving terminal device and performed

[0053] Configuration of transport protocols;

[0054] S300, obtaining the transmission protocol type supported by the video source terminal; in the present invention, the transmission

[0055] The transmission protocol types include AirPlay protocol, Miracast protocol and DLNA protocol. For each of the 5 video source terminals, the transmission protocol type supported by the video source terminal is limited by hardware and software limitations.

[0056] The technical problem to be solved by the present invention is how to let the video source terminal select a suitable transmission protocol to transmit data with the video receiving terminal device so that the video source terminal can transmit data to the video receiving terminal device in a suitable manner.

[0057] The configuration is more balanced when using various protocols;

[0058] S400, combining the protocol usage of each configured video source terminal, configuring the transmission protocol of the video source terminal by using a preset weight reduction algorithm; in the present invention, configuring the transmission protocol of the video source terminal

[0059] The transmission protocol is mainly based on the protocol usage of each video source terminal currently connected and configured by the video receiving end device. The configuration principle adopted is to try to make all the video source terminals use various transmission protocols instead of concentrating on one, so as to avoid using a certain transmission protocol.

[0060] The video source terminal exceeds the terminal's load capacity, resulting in data processing disorder and affecting data transmission efficiency;

[0061] S500, receiving the video data sent by the video source terminal based on the transmission protocol; in the present invention, after the video source terminal has configured the corresponding transmission protocol, the video source terminal receives the video data according to the configured transmission protocol.

[0062] The video data can be transmitted using the transmission protocol;

[0063] S600: Decode the video data, convert the output format, and transmit it to the display terminal for display.

[0064] The video is sent to the corresponding display device for playback. Therefore, the video receiving device decodes and converts the format after obtaining the video data.

[0065] In an optional implementation manner of the first aspect of the present invention, the combination of each configured video source

[0066] The protocol usage of the terminal, and configuring the transmission protocol 5 of the video source terminal through a preset weight reduction algorithm include:

[0067] Acquire the protocol usage of each configured video source terminal and generate a list of assigned protocols; in the present invention, for example, before configuring the transmission protocol of the video source terminal this time, N video source terminals have been connected and the corresponding transmission protocols have been assigned. In this step, the transmission protocols used by the N video source terminals that have been connected and assigned the transmission protocols are collected. This table mainly includes the items of serial number, device ID, device IP and protocol type;

[0068] Determine whether there is a type that does not belong to the allocated protocol list among the transmission protocol types supported by the video source terminal; in the present invention, for example, the protocol types supported by the video source terminal include transmission protocol 1, transmission protocol 2, transmission protocol 3 and transmission protocol 4, and the allocated protocol list records transmission protocol 1, transmission protocol 2, transmission protocol 2, transmission protocol 4, transmission protocol 4, transmission protocol 5 and transmission protocol 6. In this step, it is to see whether transmission protocol 3 that does not exist in the allocated protocol list can be found. It is also possible that there are multiple types of protocol types supported by the video source terminal that do not exist in the allocated protocol list, so there are also multiple protocol types found;

[0069] If there is a type of transmission protocol supported by the video source terminal that does not belong to the allocated protocol list, the type of transmission protocol supported by the video source terminal that does not belong to the allocated protocol list is used as the transmission protocol of the video source terminal. In the present invention, taking the above example, when the type that does not belong to the allocated protocol list is found to be transmission protocol 3, transmission protocol 3 is used as the transmission protocol between the video source terminal and the video receiving terminal device. In this step, if there are multiple types that do not belong to the allocated protocol list, then according to the release dates of multiple transmission protocols (the date of the first publication after the transmission protocol standard is formulated), the transmission protocol with the latest release date is selected as the transmission protocol between the video source terminal and the video receiving terminal device.

[0070] In an optional implementation manner of the first aspect of the present invention, the configuring the transmission protocol of the video source terminal by using a preset weight reduction algorithm in combination with the protocol usage of each configured video source terminal further includes:

[0071] If the transmission protocol types supported by the video source terminal do not include a type that does not belong to the allocated protocol list, the frequencies of various types of the transmission protocols in the allocated protocol list are counted; in the present invention, for example, if the protocol types supported by the video source terminal include transmission protocol 1, transmission protocol 2, transmission protocol 3 and transmission protocol 4, and the allocated protocol list contains transmission protocol 1, transmission protocol 2, transmission protocol 2, transmission protocol 3, transmission protocol 3, transmission protocol 4 and transmission protocol 5, that is, the transmission protocol types supported by the video source terminal do not include a type that does not belong to the allocated protocol list;

[0072] The remaining transmission bandwidth of each type of the transmission protocol is calculated by the frequency of each type of the transmission protocol; in this step, if there is no type that does not belong to the allocated protocol list among the transmission protocol types supported by the video source terminal, the present invention will count the frequency of each transmission protocol appearing in the allocated protocol list, taking the above example as an example, for example, transmission protocol 1 is 1 time, transmission protocol 2 is 2 times, transmission protocol 3 is 2 times, transmission protocol 4 is 1 time, and transmission protocol 5 is 1 time;

[0073] Calculate a first product of the frequency and a first weight coefficient; in the present invention, the value range of the first weight coefficient a is 0.2-0.4. Taking the above example, in this step, 1*a is used for transmission protocol 1, 2*a is used for transmission protocol 2, and so on;

[0074] Calculate the second product of the transmission bandwidth and the second weight coefficient; in the present invention, the video receiving end device will pre-allocate the corresponding transmission bandwidth occupation range for various transmission protocols based on the data transmission capacity (i.e., transmission bandwidth) of the used WIFI standard. Every time a video source terminal uses a certain transmission protocol, the video source terminal will divide up a section of the transmission bandwidth occupation range. The remaining transmission bandwidth is the transmission bandwidth occupation range minus the range used by its corresponding transmission protocol. After obtaining the remaining transmission bandwidth of various types of transmission protocols, in this step, the remaining transmission bandwidth of various types of transmission protocols is multiplied by a second weight coefficient. The value range of the second weight coefficient b is 0.6-0.8, the first weight coefficient is less than the second weight coefficient, and the sum of the first weight coefficient and the second weight coefficient is equal to 1;

[0075] Adding the first product and the second product to obtain recommended values ​​for various types of the transmission protocols; in this step, for example, by adding the first product and the second product, the recommended value of transmission protocol 1 is c, the recommended value of transmission protocol 2 is d, the recommended value of transmission protocol 2 is e, the recommended value of transmission protocol 4 is f, and the recommended value of transmission protocol 5 is g;

[0076] The target transmission protocol that belongs to the allocated protocol list and has the largest recommended value among the transmission protocol types supported by the video source terminal is obtained as the transmission protocol of the video source terminal. In the present invention, taking the above-mentioned recommended value result as an example, since transmission protocol 5 is not in the transmission protocol types supported by the video source terminal, it is first excluded, and then the transmission protocol corresponding to the maximum value among c, d, e, and f is selected as the transmission protocol of the video source terminal according to the size of c, d, e, and f among transmission protocol 1, transmission protocol 2, transmission protocol 3, and transmission protocol 4.

[0077] In an optional implementation manner of the first aspect of the present invention, the configuring the transmission protocol of the video source terminal by using a preset weight reduction algorithm in combination with the protocol usage of each configured video source terminal further includes:

[0078] If there are multiple target transmission protocols that belong to the assigned protocol list and have the largest recommended value among the transmission protocol types supported by the video source terminal, the target transmission protocol with the smallest frequency is selected from the multiple target transmission protocols as the transmission protocol of the video source terminal. In the present invention, taking the above-mentioned recommended value result as an example, if c and d among c, d, e, and f are the same and the largest, then the corresponding frequencies of transmission protocol 1 and transmission protocol 2 are further determined, and the frequency of transmission protocol 1 is 1 and the frequency of transmission protocol 2 is 2, then transmission protocol 1 is used as the transmission protocol of the video source terminal.

[0079] In an optional implementation manner of the first aspect of the present invention, the decoding and output format conversion of the video data and then transmitting the video data to the display terminal for display includes:

[0080] Decoding the video data according to the encoding format of the video data to obtain video decoding data; generally speaking, when recording a video, the video source terminal will use a certain format (such as H.264) to encode the obtained video, and when the display terminal device plays it, it may use another format to play it, so a format conversion needs to be performed in the video receiving terminal device. For the subsequent format conversion, the video receiving terminal device needs to decode the video data to obtain complete video data;

[0081] Obtaining a display format and display parameters supported by the display terminal; in the present invention, the video data received by the video receiving end device is ultimately used for display by the display terminal, so after the video data is decoded, it is also necessary to adjust the display format and display parameters supported by the display terminal;

[0082] Converting the video decoded data into the display format; in the present invention, the function of this step is to transcode the video decoded data into a playback format supported by the display terminal;

[0083] The resolution and frame rate of the video decoded data after format conversion are adjusted according to the display parameters to obtain target video decoded data; in the present invention, in order to obtain a better playback effect of the video decoded data after format conversion on the display terminal, the video decoded data needs to be enhanced, and the enhancement part in the present invention mainly enhances the resolution and frame rate;

[0084] The target video decoding data is transmitted to the display terminal for display. In the present invention, after the video decoding data is converted and enhanced, it is transmitted to the display terminal for display via the interface protocol used by the display.
