the method comprises the steps that step 1, a cloud server generates a plurality of interactive texts corresponding to each geographic position coordinate in a preset effective interactive geographic range by taking each geographic position coordinate in a geographic position coordinate database as a central point, establishes a first association between each interactive text and the corresponding geographic position coordinate, and establishes a second association between each interactive text and all the geographic position coordinates in the effective interactive geographic range.

In specific implementation, a geographic position coordinate database is usually set on the cloud server, and all geographic position coordinates in the current jurisdiction, including geographic position coordinates of all playback devices in the jurisdiction, are stored in the geographic position coordinate database.

And 2, receiving interactive text request information sent by the playing equipment, wherein the interactive text request information comprises the geographical position coordinates of the playing equipment, the preset number of the interactive texts and the ID of the playing equipment, and the geographical position coordinates of the playing equipment are stored in a geographical position coordinate database. Usually, the playback device ID includes a communication address of the playback device.

In specific implementation, the playing device may be a television, a computer, an outdoor screen, a vehicle-mounted screen, or other playing devices.

And 3, the cloud server selects all interactive texts which establish a first association with the geographical position coordinates of the playing equipment from the geographical position coordinate database according to the geographical position coordinate information in the interactive text request information sent by the playing equipment, selects a preset number of interactive texts which do not establish an association with other playing equipment IDs from all the interactive texts, and establishes a third association between the selected preset number of interactive texts and the playing equipment IDs.

In one embodiment, all interactive texts having a first association with the geographic location coordinates in the geographic location coordinates database have a single association with the playback device ID, i.e. each interactive text can only establish a third association with one playback device ID at the same time. For example, if the preset number of the interactive texts in the interactive text request sent by the playing device to the cloud server is 5, but 20 interactive texts that establish the first association with the geographic position coordinates of the playing device exist, where 5 interactive texts already establish the third association with other playing device IDs, the cloud server selects 5 interactive texts from the remaining 15 interactive texts that do not establish the third association with the playing device ID information and establishes the third association with the playing device ID.

And 4, the cloud server sends the interactive texts with the preset quantity selected in the step 3 to the playing equipment.

And 5, the playing equipment receives a preset number of interactive texts sent by the cloud server and stores the interactive texts in an interactive text memory.

And 6, the playing equipment acquires video data. The video data comprises video image data and a plurality of interactive contents, and each interactive content comprises interactive information, display duration of an interactive text, first keeping associated duration of the interactive text and display position coordinate information. Wherein the interactive content is edited at a time point in a playback time axis of the video data.

Generally, the video data may come from a video database, from a network, or from a video editor.

Step 7, in the process of playing the video data by the playing device, when the video data is played to the time point when the interactive content is edited, inquiring the interactive content at the time point, selecting the interactive texts with the same quantity as the inquired interactive contents from the interactive text memory and establishing a fourth association with the inquired interactive contents; the playing device displays an interactive text establishing a fourth association with the inquired interactive content at a corresponding position in a screen of the playing device according to the coordinate information of the display position in the inquired interactive content; when the display duration of the interactive text reaches the display duration of the interactive text in the interactive content establishing the fourth association with the interactive text, finishing the display of the interactive text in the screen; and when the association duration of the interactive text reaches the first remaining association duration in the interactive content establishing the fourth association with the interactive text, canceling the association between the interactive text and the interactive content.

In specific implementation, when the playing device plays the video data, the playing device selects a corresponding number of interactive texts from the interactive text memory according to the number of the interactive contents in the current playing time point to respectively establish a one-to-one association, i.e. a fourth association, with the corresponding number of interactive contents in the current playing time point, and respectively displays the interactive texts established with the interactive texts at corresponding positions in the display screen of the playing device according to the coordinate information of the display positions in the corresponding number of interactive contents.

In one embodiment, the interactive information in the interactive content may be a website link, a telephone number, address information, and the like. For example, the playing device obtains an advertisement video containing 3 interactive contents, the interactive information in the 3 interactive contents is a telephone number dialing instruction, a website link opening instruction, and an address navigation instruction, when the advertisement video is played, the playing device randomly selects 3 interactive texts 001, 010, and 100 from an interactive text memory to establish association with the 3 interactive contents, and displays the 3 interactive contents at corresponding positions in a screen according to display position coordinate information in the 3 interactive contents.

The first keeping associated duration of the interactive text refers to the duration when the interactive text is includedAfter the video of the interactive content with the fourth association is played, the playing device keeps the fourth association established between the interactive content and the interactive text within a first association keeping duration, where the first association keeping duration is a preset association duration, for example, an interactive text a is played₁Is set to 5 minutes, when containing the interactive text a₁After the video of the interactive content establishing the fourth association is played, the time still does not reach 5 minutes, and the playing equipment keeps the interactive content and the interactive text a₁The fourth correlation established between the two was maintained for a total of 5 minutes.

And 8, the cloud server receives an interactive text input instruction sent by the terminal, wherein the interactive text input instruction comprises interactive text input information, the geographic position coordinates of the terminal and a communication address.

In a specific implementation, the terminal may be a mobile terminal such as a mobile phone, a PDA, a tablet computer, or a non-mobile terminal such as a desktop computer.

And 9, the cloud server inquires whether the interactive text which is the same as the interactive text in the interactive text input information exists in the interactive text which is in second association with the geographic position coordinate of the terminal. If so, the next step is performed.

The interactive text input information generally comprises interactive texts, and in the specific implementation, the cloud server searches the geographic position coordinate database, firstly determines whether the geographic position coordinates of the terminal exist in the geographic position coordinate database, and if yes, the cloud server generates a plurality of interactive texts for the geographic position coordinates in the step 1; the cloud server can search the interactive text which is the same as the interactive text in the interactive text input information in the interactive text which is established with the geographic position coordinates of the terminal.

And step 10, establishing a third associated playing device ID according to the interactive text in the interactive text input information, and sending the communication address of the terminal and the interactive text input information to corresponding playing devices.

And 11, the playing equipment sends the interactive information in the interactive content associated with the interactive text in the interactive text input information to the terminal according to the communication address of the terminal sent by the cloud server.

And 12, the terminal receives the interactive information, and correspondingly operates and displays the interactive information according to the type of the interactive information.

In specific implementation, the playing device can be a television, a computer, an outdoor large screen and other playing devices, and the interactive information can be website links, telephone numbers, address information, audio and video data and other contents; the terminal can be a mobile terminal such as a mobile phone, a PDA, a tablet computer and the like or a non-mobile terminal such as a desktop computer and the like. The invention is only explained by taking a terminal as an intelligent mobile phone as an example, when the intelligent mobile phone receives the interactive information and judges that the interactive information is address navigation information, the intelligent mobile phone automatically opens a map navigation program to plan a navigation route from the current geographic position of the intelligent mobile phone to a destination in the interactive information.

An embodiment of the interaction method based on the geographical location information is further provided as follows.

The method comprises the steps that a playing device obtains video data containing at least one interactive content and sends interactive text request information to a cloud server, wherein the interactive text request information comprises geographic space position coordinate information of the playing device, interactive geographic space range selection information based on the geographic space position coordinate information of the playing device, interactive text generation quantity information, communication address information of the playing device and ID information.

After receiving the interactive text request information, the cloud server determines a corresponding interactive geographic space range according to geographic space position coordinate information and interactive geographic space range selection information based on the geographic space position coordinate information, generates a plurality of interactive texts effective in the interactive geographic space range according to a preset interactive text generation rule, duplicates the effective interactive texts into two same parts, writes communication address information, ID information and interactive geographic space range information of playing equipment into one interactive text, generates a plurality of interactive items and stores the interactive items into an interactive item database, and sends the other interactive text to the playing equipment.

And when the playing equipment receives the interactive text, the interactive text is respectively associated with the interactive contents with the corresponding quantity in the video data and stored in an interactive content memory. And when the video data is played, displaying the corresponding interactive text related to the interactive content at the corresponding position in the display screen of the playing equipment according to the display position information of the interactive content.

The cloud server or the playing device can receive an interactive text input instruction from the terminal, find out interactive content associated with interactive text information in the interactive text input instruction according to the interactive text input instruction, and then send the interactive information in the interactive content to the terminal.

And the terminal receives the interactive information and performs corresponding operation and display.

The preset interactive text generation rule comprises the following steps: the cloud server determines an interactive geographic space range for generating interactive texts, detects interactive texts covering partial areas or all areas of the existing interactive geographic space range to the interactive geographic space range for generating the interactive texts, selects and generates a plurality of interactive texts which are unique in the interactive geographic space range and not repeated with other existing interactive texts from an interactive text source database, and therefore the situation that the interactive geographic space ranges of two identical interactive texts are overlapped does not exist. For example, when the cloud server receives interactive text request information sent by a playing device, and the interactive text request information requests the cloud server to generate 5 effective interactive texts in a specified geographic space range, the cloud server determines a corresponding interactive geographic space range according to the interactive text request information, and then detects that a part of or all of the interactive geographic space range of 10 interactive texts covers the interactive geographic space range, the 10 interactive texts are excluded from the interactive text source database when 5 interactive texts are selected and generated from the interactive text source database.

Fig. 2 is a schematic diagram illustrating establishment of a first association and a second association according to an embodiment of the present invention. The cloud server generates 10 interactive texts a within a range of 100 meters with the coordinate a as a central point for geographic position coordinate a (for convenience of description, hereinafter referred to as coordinate a) in the geographic position coordinate database₁～a₁₀And establishing a first association between the 10 interactive texts and the corresponding coordinates A, and simultaneously associating each of the 10 interactive texts with all coordinates (i.e. coordinates A, A) within a 100-meter range taking the coordinates A as a center point₁、A₂、A₃、A₄) Establishing a second association, wherein each interactive text has uniqueness within a range of 100 meters with the coordinate A as a central point, namely, each interactive text (for example, a)₂～a₁₀Any of) with all coordinates already within the range (i.e., coordinates A, A)₁、A₂、A₃) The other interactive texts establishing the second association are not the same. And the uniqueness is also embodied in the interaction text a₁Establishing a second associated coordinate A₄Not only in a circle with the coordinate A as the central point, but also in a circle with the geographic position coordinate B as the central point, due to the interactive text a₁Has been associated with the coordinate A₄If the second association is established, the interactive text a needs to be excluded when generating the interactive text of the geographic position coordinate B for establishing the first association₁。

In an embodiment, the playing device may further display the effective interactive geographic range of the interactive text displayed in the current screen beside the display position of the corresponding interactive text in the screen.

For example, interactive text a displayed on the screen of a playback device₁Is to interact with the interactive text a₁Set up the firstIf the associated geographic position coordinate A is a range with the central point and the radius of 100 meters, the playing equipment displays the radius of 100 meters in the interactive text a₁To the lateral position of (c).

In an embodiment, the interactive text may be one of a simple number, a simple letter, a simple character, or a combination thereof. For example, the interactive text may be 01, AB, Zhang three, A1, LiA, etc.

The cloud server sets an effective display range for all interactive texts establishing first association with each geographic position coordinate in the geographic position coordinate database, and the effective display range of each interactive text is in the effective interactive geographic range corresponding to the interactive text and is smaller than the effective interactive geographic range corresponding to the interactive text. And when the geographic position coordinates of the playing device are moved out of the effective display range of the interactive text which is in the fourth association with the interactive content and is displayed in the screen, canceling the display of the interactive text in the screen. For example, some interactive text a₂The effective interactive geographical range of (1) is within a circle with a radius of 100 meters and the geographical position coordinate a with which the first association is established is taken as a center point, and then the effective display range of the interactive text can be set to be within a circle with a radius of 50 meters and the coordinate a as a center point.

The cloud server sets a second association keeping duration for each interactive text in all interactive texts establishing first association with each geographic position coordinate in the geographic position coordinate database, and when the geographic position coordinate of the playing device is out of an effective display range of the interactive text establishing fourth association with certain interactive content in the second association keeping duration, the cloud server keeps third association established between the interactive text and the ID information of the playing device in the geographic position coordinate database. For example, the cloud server gives the interactive text a₃The second stay associated duration is set to 10 minutes when associated with the interactive text a₃Playing equipment for establishing third association moves out interactive text a₃When the display range is effective, the cloud server keeps the interactive text a within 10 minutes₃And establishing a third association with the ID information of the playing device.

In an embodiment, the interaction method further includes the steps that the cloud server monitors a change of the geographic position coordinates of the playing device, and when the geographic position coordinates of the playing device are shifted out of an effective display range of the interactive text in the interactive text memory, the cloud server recognizes that the association states of the interactive texts in the interactive text memory mainly include the following three association states:
