Detailed Description
So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
With reference to fig. 1, an embodiment of the present disclosure provides a method for transmitting smell characteristic data, including:
step s100, detecting the embedded point information in the multimedia data stream being played;
step s200, when the buried point information is detected, sending odor characteristic data indicated by the buried point information;
the embedded point information is used for indicating the characteristics of the smell, and the smell characteristic data indicated by the embedded point information is related to the content to be played in the multimedia data stream.
By adopting the embodiment of the disclosure, the data has the embedded point information indicating the characteristics of the odor, the odor characteristic data is sent by detecting the embedded point information, the opportunity for sending the odor characteristic data is controllable, the odor characteristic data can be sent to a position close to a user for modulation and odor emission, the time delay of the user for smelling the odor is reduced, and the sensory experience of the user is improved.
Optionally, the detecting the buried point information in the multimedia data stream being played includes: the buried point information in the data is identified by reading the data of the multimedia data stream. For example, a multimedia data stream with a length of 10 minutes is read, and the buried point information is identified at a node of 5 minutes, that is, the buried point information in the multimedia data stream being played is detected at 5 minutes.
Optionally, the multimedia data stream comprises: audio data or video data. By adopting the optional embodiment, when the user enjoys the audio data, the odor characteristic indicated by the embedded point information in the audio data is detected, and when the user enjoys the video data, the odor characteristic indicated by the embedded point information in the video data is detected, so that the appreciation range of the multimedia content is expanded, and the user experience is improved.
Optionally, the characteristic of the scent (i.e., the scent characteristic) is a characteristic of a scent emitted by an object having a scent; the object with the smell can be a picture of the object appearing in the video or a keyword related to the object in the audio. For example, when a picture of wine appears in a video, the smell is characterized by the wine flavor given out by the wine.
Alternatively, the smell characteristic data is data information of characteristics constituting the smell. For example, the odor is characterized by a wine flavor, and the odor characteristic data is data constituting the wine flavor, by which the wine flavor can be formulated.
Optionally, the multimedia data stream comprises feature points for indicating the location of the scent features in the multimedia data stream. By adopting the optional embodiment, the odor characteristic data in the multimedia data stream is positioned through the characteristic points, and then the position of the embedded point information indicating the odor characteristic data is positioned, so that the embedded point information of the multimedia data stream can be detected and identified more accurately and efficiently.
Optionally, the position of the feature of the smell in the multimedia data stream refers to a time point when an article corresponding to the feature of the smell appears in the multimedia data stream. For example, a multimedia data stream with a duration of 10 minutes, a picture of wine appears at 55 seconds in 3 minutes, i.e. 55 seconds in 3 minutes is the position in the multimedia data stream of the odor characteristic representing the aroma of wine.
Optionally, the embedded point information is a segment of bytes marked in the multimedia data stream, and the byte corresponds to a smell characteristic data. By adopting the optional embodiment, the time node which needs to send the odor characteristic data can be marked by marking the bytes into the multimedia data stream, and the bytes occupy less memory, so that the detection and reading speed can be improved. For example, if the information of the embedded point is '00001', the corresponding odor characteristic is the aroma of the wine, and '00001' is marked in the multimedia data stream for 54 seconds at the 3 rd minute, the embedded point information indicating the aroma of the wine is detected at 54 seconds at the 3 rd minute after the multimedia data stream is played, and the data corresponding to the aroma of the wine and forming the aroma of the wine is sent out.
Alternatively, the buried point information may be manually tagged into the multimedia data stream. By adopting the optional embodiment, the embedded point information is manually marked in the multimedia data stream, the position of the characteristic point marked in the multimedia data stream by the embedded point information can be manually selected, and the accuracy of the embedded point information marking is improved. For example, a piece of video data is played, and when wine appears in the video data, buried point information is manually marked at a time node at which the wine appears in the video data.
Optionally, when there is no feature point in the multimedia data stream, the embedded point information is manually marked into the multimedia data stream. By adopting the optional embodiment, when no characteristic point exists in the multimedia data stream, the buried point information is manually marked in the multimedia data stream without the characteristic point, so that the difficulty of marking the buried point information is reduced. For example, the played multimedia data stream is Buddha song, which has no characteristic point with sandalwood fragrance, but can manually mark the embedded point information corresponding to sandalwood fragrance in Buddha song.
Alternatively, the buried point information may be automatically marked into the multimedia data stream upon detection of the characteristic point. By adopting the optional embodiment, the embedded point information is automatically marked into the multimedia data stream after the characteristic points in the multimedia data stream are detected, so that the embedded point information marking efficiency can be improved, and the embedded point information marking time can be shortened.
Optionally, detecting the feature points comprises detecting the feature points in the multimedia data stream by an image recognition technique or a speech recognition technique. By adopting the optional embodiment, the characteristic points in the multimedia data stream are identified through the image identification technology or the voice identification technology, so that the characteristic points can be identified more efficiently, and the marking of the embedded point information is facilitated. For example, a picture of wine appears in a section of video data in the playing process, and the time point of the appearance of the wine is identified as the characteristic point of the wine by an image identification technology; the voice of the roses appears in the audio data in the playing process, and the time points of the roses, which are identified by the voice identification technology, are the characteristic points of the roses.
Optionally, the buried point information is set at the feature point, or before the feature point, or within a first preset range after the feature point. By adopting the optional embodiment, the positions of the embedded point information are set in a diversified manner according to different odor diffusion speeds, so that the odor diffusion device can adapt to odors with different diffusion speeds, and the sensory experience of a user is improved.
Optionally, the buried point information is set at the characteristic point. By adopting the optional embodiment, when the multimedia data stream is played to the node with the characteristic point, the embedded point information arranged at the characteristic point is detected at the same time, so that the odor characteristic data in the multimedia data stream is detected while being played, the real-time performance of detecting the embedded point information in the multimedia data stream is improved, and the sensory experience of a user is improved.
Optionally, the buried point information is set before the feature points. By adopting the optional embodiment, the embedded point information is arranged in front of the characteristic point in the multimedia data stream, so that the embedded point information is detected before the characteristic point when the multimedia data stream is played, the odor characteristic data at the characteristic point is sent out before the playing progress, the method is suitable for diffusing slower odor, and the sensory experience of a user is improved.
Optionally, the buried point information is set within a first preset range after the characteristic point. By adopting the optional embodiment, the embedded point information is arranged in the first preset range behind the feature point in the multimedia data stream, so that the multimedia data stream is played to the feature point and then the embedded point information is detected to send the odor feature data, a user can firstly perceive the odor feature and then smell the odor corresponding to the odor feature, and the user is more real in sense. For example, when wine appears in a multimedia data stream watched by a user, but the visual angle of a lens is far away from the position of the wine, theoretically, a period of time is needed for wine aroma to diffuse to the visual angle watched by the user, at the moment, buried point information is detected in a period of time after the smell characteristic representing the wine appears, and the smell characteristic data is sent, so that the wine aroma is modulated and sent out, and the sense of the user can be more real.
Optionally, the first preset range is set according to an appearance scene of the odor feature corresponding to the feature point. By adopting the optional embodiment, the first preset range is set according to the different scenes of the odor characteristics, so that the sensory experience of the user is relatively real.
Optionally, the scene of occurrence of the odor features includes: and the distance of the object corresponding to the odor characteristic in the video data stream from the visual angle of the lens. By adopting the optional embodiment, the first preset range is set through the distance between the object corresponding to the odor characteristic in the video data stream and the visual angle of the lens, so that the sensory experience of a user is relatively real. For example, when wine appears in the video data and the angle of view of the lens is far away from the wine, the first preset range is set to be 3-5 seconds after the characteristic point of the wine appears, so that the process that a user smells the bouquet is delayed by 3-5 seconds, and the sensory experience of the user is more real.
Optionally, the first preset range is within 5 seconds (including 5 seconds) after the feature point. By adopting the optional embodiment, when an article corresponding to the odor characteristic is far away from the visual angle of the lens in the multimedia data stream, the user can delay smelling the odor characteristic of the article through the setting of the first preset range, so that the sensory experience of the user is more real.
Optionally, the buried point information precedes the characteristic point in the content to be played by 0.1-5 seconds. By adopting the optional embodiment, a certain time is required for sending and spreading the smell, the time sensed by the smell sense of the user after the smell is sent is generally more than or equal to 0.1 second and less than or equal to 5 seconds, the embedded point information is 0.1-5 seconds before the characteristic point in the content to be played, the embedded point information is detected and sent to the smell characteristic data for configuring and sending the smell before 0.1-5 seconds before the characteristic point, the user can enjoy the smell characteristics corresponding to the characteristic point sensed by other senses of the multimedia data stream, and the corresponding smell is smelt at the same time, so that the sensory experience of the user is improved.
Optionally, the detection of the buried point information in the multimedia data stream is started at the same time as the playing of the multimedia data stream is started. By adopting the optional embodiment, the user can listen to the multimedia data stream, simultaneously detect the embedded point information and send the odor characteristic data according to the embedded point information, so that the user can smell the odor at the same time, and the sensory experience of the user is improved.
Optionally, it is detected that the progress of the buried point information in the multimedia data stream is consistent with the progress of playing the multimedia data stream. By adopting the optional embodiment, the detection progress of the embedded point information is controlled to be consistent with the playing progress of the multimedia data stream, so that the embedded point information detection error caused by the inconsistency of the detection progress of the embedded point information and the playing progress of the multimedia data stream is prevented, and the accuracy of the embedded point information detection in the multimedia data stream is improved. For example, in a multimedia data stream with a 10-minute session, when the stream is played to the 3 rd minute, the progress of detecting the embedded point information in the multimedia data stream also reaches the 3 rd minute.
