[0001] The present invention relates to the field of vehicle-mounted video playback, and in particular to a multi-timeline expression method, device and equipment for vehicle-mounted video. Background Art

[0002] During vehicle driving, there is often a need to play in-vehicle videos so that passengers can have leisure and entertainment and relieve boredom while riding.

[0003] However, the in-vehicle videos in related technologies often develop in a single timeline with a fixed plot. For different people with different plot preferences, or individuals in different emotional states, the fixed plot development will greatly reduce the leisure and entertainment effect for passengers. Therefore, further improvement is needed. Summary of the invention

[0004] The main purpose of the present invention is to provide a multi-timeline expression method, device and equipment for vehicle-mounted video, aiming to solve the problem of large limitations of vehicle-mounted video in related technologies.

[0005] In a first aspect, the present invention provides a multi-timeline expression method for vehicle-mounted video.

[0006] A multi-timeline expression method for vehicle-mounted video, comprising the following steps:

[0007] In response to an interactive instruction about a next video segment, a video segment having a content feature attribute corresponding to the interactive instruction and the played video is selected from the video segments in the set candidate video pool as a target video segment; wherein the content feature attribute is attribute data of an object appearing in the video segment;

[0008] When a signal for playing the next video segment is obtained, the target video segment is output.

[0009] Through the above method, by responding to the input interactive instructions, the development timeline of the in-vehicle video can be changed to the timeline of the corresponding interactive instructions, so that when facing different viewing needs, the development timeline of the in-vehicle video can be adjusted in time, thereby significantly improving the leisure and entertainment effect of the in-vehicle video in the vehicle.

[0010] In some embodiments, the step of responding to the interactive instruction regarding the next video segment and selecting, from the video segments in the candidate video pool, a video segment having content feature attributes corresponding to the interactive instruction and the played video as the target video segment comprises the following steps:

[0011] Update the content feature attributes corresponding to the played video according to the interactive instruction to obtain the target feature attributes;

[0012] According to the target feature attribute, updating the candidate video pool;

[0013] A video segment is selected from the candidate video pool as a target video segment.

[0014] Through the above method, it is possible to update the content feature attributes of the played video through interactive instructions, obtain the target feature attributes of the next video segment, and further screen the video segments from the candidate video pool through the target feature attributes.

[0015] In some embodiments, the candidate video pool is updated according to the target feature attribute.

[0016] The video segments are retained in the candidate video pool or excluded from the candidate video pool according to whether the content feature attributes of each video segment in the candidate video pool at the end of the video meet the target feature attributes.

[0017] Through the above method, the candidate video pool is dynamically updated according to the interactive instruction, thereby ensuring that the next video segment played is always a video segment that meets the relevant requirements.

[0018] In some embodiments, the step of selecting a video segment from the candidate video pool as the video segment includes:

[0019] If there are multiple video clips in the candidate video pool, the vehicle driving state parameter is obtained, and a video clip is selected as the target video clip according to the vehicle driving state parameter.

[0020] Through the above method, after the interactive instruction updates the candidate video pool, if there are still multiple selectable video clips, this case will further select a video clip that better matches the vehicle driving state parameters as the next video clip. For example, when it is currently raining, a video clip with a plot developing into a rainy day is selected as the next video clip, so as to be closer to the audience's current viewing state, making their experience better and their immersion stronger.

[0021] In some embodiments, the vehicle driving state parameters include one or more of the remaining distance of the target location navigation path, the remaining driving time of the target location navigation path, the vehicle rain sensor, and the network standard time.

[0022] Through the above method, it is possible to combine one or more of the remaining driving time, external environment data, and network standard time when screening the target video clips, so that in the subsequent playback process, the complete plot can be played smoothly, or the effect can be more in line with the external environment and real time.

[0023] In some embodiments, the attribute data includes attribute record data and attribute operation data of each object in the video at each time point, and the attribute record data is updated along with the attribute operation data at each time point.

[0024] In some embodiments, when the signal for playing the next video segment is obtained, before the target video segment is output, the following steps are included:

[0025] After the currently played video segment is finished, a signal for playing the next video segment is generated; or, after responding to the interactive instruction, a signal for playing the next video segment is generated.

[0026] In some embodiments, the step of responding to the interactive instruction about the next video segment and selecting, from the video segments in the candidate video pool, a video segment with content feature attributes corresponding to the interactive instruction and the played video as the target video segment includes the following steps:

[0027] Obtain video construction information for constructing a candidate video pool, and select multiple video clips corresponding to the video construction information from a preset video library to form a backup video pool; wherein the video construction information includes one or more of audience number information, audience age information, travel duration, and external environment data.

[0028] Through the above method, before playing the first video clip, it is possible to filter and establish a suitable backup video pool from the video library based on the acquired video construction information, thereby achieving an effect that better meets the needs of the audience.

[0029] In a second aspect, the present invention also provides a multi-timeline expression device for vehicle-mounted video.

[0043] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0044] During vehicle driving, there is often a need to play in-vehicle videos so that passengers can have leisure and entertainment and relieve boredom while riding.

[0045] However, the in-vehicle videos in related technologies often develop in a single timeline with a fixed plot. For different people with different plot preferences, or individuals in different emotional states, the fixed plot development will greatly reduce the leisure and entertainment effect for passengers. Therefore, further improvement is needed.

[0046] Based on this, the embodiments of the present invention provide a multi-timeline expression method, device and equipment for in-vehicle video. The key point of the invention is that by responding to the input interactive instructions, the development timeline of the in-vehicle video can be changed to the timeline of the corresponding interactive instructions, so that when facing different viewing needs, the development timeline of the in-vehicle video can be adjusted in time, thereby significantly improving the leisure and entertainment effect achieved by the in-vehicle video in the vehicle.

[0047] In a first aspect, an embodiment of the present invention provides a multi-timeline expression device for vehicle-mounted video, which may be a device having a data processing function such as a vehicle control unit (VECU).

[0048] Reference Figure 1 , Figure 1 The hardware structure diagram of the multi-timeline expression device of the vehicle-mounted video involved in the embodiment of the present invention is shown in FIG. In the embodiment of the present invention, the multi-timeline expression device of the vehicle-mounted video may include a processor 1001 (e.g., a central processing unit, CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components; the user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard); the network interface 1004 may optionally include a standard wired interface, a wireless interface (such as a wireless fidelity WIreless-FIdelity, WI-FI interface); the memory 1005 may be a high-speed random access memory (random access memory, RAM), or a stable memory (non-volatile memory), such as a disk storage, and the memory 1005 may optionally be a storage device independent of the aforementioned processor 1001. Those skilled in the art will understand that Figure 1 The hardware structure shown in the figure does not constitute a limitation of the present invention, and may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0049] Continue to refer to Figure 1 , Figure 1The memory 1005 as a computer storage medium may include an operating system, a network communication module, a user interface module, and a multi-timeline expression program for vehicle-mounted videos. The processor 1001 may call the multi-timeline expression program for vehicle-mounted videos stored in the memory 1005 and execute the multi-timeline expression method for vehicle-mounted videos provided in an embodiment of the present invention.

[0050] In a second aspect, an embodiment of the present invention provides a multi-timeline expression method for vehicle-mounted video.

[0051] Reference Figure 2 , a multi-timeline expression method of vehicle-mounted video, comprising:

[0052] S100, in response to an interactive instruction regarding a next video segment, selecting a video segment whose content feature attribute corresponds to the interactive instruction and the played video from the video segments in a set candidate video pool as a target video segment; wherein the content feature attribute is attribute data of an object appearing in the video segment;

[0053] S200: When a signal for playing the next video segment is obtained, the target video segment is output.

[0054] Among them, regarding the interactive instruction in step S100, in different embodiments, it can be obtained at various stages such as before, during, and after the previous video is played, and its acquisition means is specifically to output an interactive signal containing multiple interactive results, and form a corresponding interactive instruction according to the result of the passenger's selection in response to the interactive signal. The specific form of the interactive signal can be a pop-up window of options on the video playback device, or a selection signal sent to another terminal, such as a user's mobile terminal, and this application does not limit this.

[0055] The attribute data constituting the characteristic attributes of the content of the video clip specifically include, but are not limited to, the state attributes of each object and each person in the video clip at different time points, the associated attributes of each object and each person with other objects or people at different time points, the attribute record data such as the position attributes, and the attribute operation data used to operate the attribute data of each object in the playback content. The attribute record data is updated with the attribute operation data at each time point. For example, when an object or a person object is in a moving state in the plot of the video, the corresponding position attribute data will be affected by the attribute operation data and change to the new position attribute data. When the relationship between two person objects changes in the plot of the video, it means that the attribute operation data for modifying the relationship between the two characters exists at a specific time point, and the connection between the two characters is adjusted to the latest attribute record data.

[0056] The interactive instructions are used to adjust the content feature attributes of the objects that appear in the next video clip. For example, when the audience wants to see character A and character B establish a marriage relationship, they can filter out video clips that meet the content feature attributes from multiple video clips in the alternative video pool. Therefore, it can be seen that the selection of the next video clip will depend on both the interactive instructions fed back by the user and the content feature attributes that have appeared in the played video.

[0057] With this arrangement, by responding to the input interactive commands, the development timeline of the in-vehicle video can be changed to the timeline of the corresponding interactive commands, and then the development timeline of the in-vehicle video can be adjusted in time when facing different viewing needs, thereby significantly improving the leisure and entertainment effect of the in-vehicle video in the vehicle.

[0058] Furthermore, the step S100, in response to the interaction instruction about the next video segment, selecting a video segment whose content feature attribute corresponds to the interaction instruction and the played video from the video segments in the candidate video pool as the target video segment, includes the following steps:

[0059] S110, updating the content feature attribute corresponding to the played video according to the interaction instruction to obtain a target feature attribute;

[0060] S120, updating the candidate video pool according to the target feature attribute;

[0061] S130: Select a video segment from the candidate video pool as a target video segment.

[0062] In this way, the content feature attributes of the played video can be updated through interactive instructions to obtain the target feature attributes of the next video segment, and the video segments can be further screened from the candidate video pool based on the target feature attributes.

[0063] Specifically, in step S120, the candidate video pool is updated according to the target feature attribute.

[0064] The video segments are retained in the candidate video pool or excluded from the candidate video pool according to whether the content feature attributes of each video segment in the candidate video pool at the end of the video meet the target feature attributes.

[0065] This arrangement enables the candidate video pool to be dynamically updated according to the interactive instruction, thereby ensuring that the next video segment played is always a video segment that meets the relevant requirements.

[0066] Further, in some preferred embodiments, the step of selecting a video segment from the candidate video pool as the video segment is as follows:

[0067] If there are multiple video clips in the candidate video pool, a vehicle driving state parameter is obtained, and a video clip is selected as a target video clip according to the vehicle driving state parameter.

[0068] Specifically, after the interactive instruction updates the candidate video pool, if there are still multiple selectable video clips, the case will further select a video clip that better matches the vehicle driving state parameters as the next video clip. For example, when it is currently raining, a video clip with a plot that develops into a rainy day is selected as the next video clip to be closer to the audience's current viewing state, giving them a better experience and a stronger sense of immersion.

[0069] Furthermore, in this embodiment, the vehicle driving state parameters include one or more of the remaining distance of the target location navigation path, the remaining driving time of the target location navigation path, external environment data, and network standard time.

[0070] With this arrangement, it is possible to combine one or more of the remaining driving time, external environment data, and network standard time when screening the target video clips, and then in the subsequent playback process, it is possible to smoothly play the complete plot, or achieve effects that are more in line with the external environment and actual time.

[0071] The external environment data at least includes external temperature data and external rainfall data.

[0072] Further, in some preferred implementations, when the signal for playing the next video segment is obtained in step S200, before the target video segment is output, the following steps are included:

[0073] After the currently played video segment is finished, a signal for playing the next video segment is generated; or, after responding to the interactive instruction, a signal for playing the next video segment is generated.

[0074] Further, in some preferred embodiments, before the step S100, in response to the interactive instruction about the next video segment, selecting a video segment whose content feature attribute corresponds to the interactive instruction and the played video from the video segments in the candidate video pool as the target video segment, includes the following steps:

[0075] S010. Obtain video construction information for constructing a candidate video pool, and select multiple video clips corresponding to the video construction information from a preset video library to form a backup video pool; wherein the video construction information includes one or more of audience number information, audience age information, travel duration, and external environment data.

[0076] With this arrangement, before playing the first video clip, it is possible to filter and build a suitable backup video pool from the video library based on the acquired video construction information, thereby achieving an effect that better meets the needs of the audience.
