Furthermore, the drawings are merely schematic illustrations of the invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the steps. For example, some steps may be decomposed, and some steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
The method and the device are preferably used for improving the situation that when the playing device is in a dormant state, when a user wants to know further contents of a currently played audio course, the corresponding contents are difficult to display and position, so that the user cannot understand audio data, needs to manually search and find the corresponding contents for understanding, and the user experience is poor.
Fig. 1 shows a flowchart of a multimedia data playing method of associated audio according to an embodiment of the present invention. The multimedia data playing method of the associated audio comprises the following steps:
step S110: in response to a wake-up operation on the playback device, current playback information of the played audio data is determined.
Specifically, the playing device described in each example of the present invention may be a mobile smart device such as a mobile phone, a smart watch, a tablet computer, and a notebook computer.
Specifically, step S110 is performed on the premise that the playback device is in the hibernation state, i.e., the display screen of the playback device does not display any content.
Step S120: and determining multimedia data to be played from the multimedia data associated with the played audio data according to the current playing information.
Step S130: and playing the determined multimedia data to be played on a screen of the playing equipment.
In the audio-associated multimedia data playing method provided by the invention, the students can respond to the awakening of the screen while listening to the audio courses and provide the associated multimedia data for the students, so that the audio courses are perfected, the flow is saved, and the requirement on network bandwidth is reduced.
In some embodiments of the invention, the multimedia data associated with the audio data is one or more of courseware, video lessons, and network-associated data associated with the audio data. Courseware can be played in picture, PPT and PDF formats. In the application of the audio course, the provided audio data is the audio of the video course, so that each audio data can be directly associated with the video course when the audio data is generated. The video lessons are played in the form of video streams. The network associated data is multimedia data crawled from the internet according to the audio data. For example, multimedia data (including text, pictures, video) may be crawled from the internet based on one or more of the title of the audio data, keywords, the teacher of the audio source, and so on. When a plurality of multimedia data are crawled, the multimedia data can be selected according to a set algorithm rule. For example, the dimensions of the keyword frequency, the title similarity calculation, the playing amount, and the like are set according to the algorithm specification, and the present invention can implement more variation modes, which is not described herein. When the played multimedia data contains audio, the played multimedia data can be muted, or the audio data being played can be paused, and the audio of the multimedia data to be played can be played.
In some embodiments of the present invention, the current playing information is a current time stamp of the played audio data, and the multimedia data associated with the played audio data is indexed by the time stamp. The step S120 shown in fig. 1 of determining multimedia data to be played from the multimedia data associated with the audio data according to the current playing information may include the following steps: and determining multimedia data to be played according to the multimedia data associated with the audio data played by the current timestamp, wherein the multimedia data to be played is used for performing supplementary display on the content of the audio data played by the current timestamp.
For example, when the multimedia data is a video session, the audio data is extracted from the corresponding video session, and the audio data and the video session are temporally aligned, so that the time stamp of the audio data and the time stamp of the video session are aligned (even if the audio data is captured during the extraction, the audio data and the video session can be previously operated to correspond to each other at the time stamps). In step S120, according to the current timestamp of the audio data, the position of the video course corresponding to the timestamp can be located, and the video content after the corresponding timestamp of the video course starts is used as the multimedia data to be played, and the video content after the corresponding timestamp of the video course starts is played through step S130.
For example, when the multimedia data is a corresponding courseware, the courseware is generally used in a video course correspondingly, and therefore, the time stamp of the video course can be associated with the content of each page of the courseware (for example, the time of the first page of the courseware is 0:00-3:20, and the time of the second page of the courseware is 3:21-7: 10.). Thus, according to the above, the time stamp of the audio data and the time stamp of the video lesson are matched with each other, and therefore, the time stamp of the audio data is associated with each page of the courseware. In step S120, according to the current timestamp of the audio data, the number of pages of the courseware corresponding to the timestamp can be located, and the current number of pages of the courseware and the courseware are taken as multimedia data to be played, the current number of pages of the courseware is played through step S130, and the number of pages of the courseware is correspondingly switched along with the playing of the audio data.
In some embodiments of the present invention, the current playing information is a current text content of the played audio data, which is converted by a speech text, and the multimedia data associated with the played audio data is indexed by the text content. The step S120 shown in fig. 1 of determining the multimedia data to be played from the multimedia data associated with the audio data according to the current playing information includes the following steps: and determining multimedia data to be played according to the multimedia data associated with the audio data of the self-played current text content, wherein the multimedia data to be played is used for performing supplementary display on the current text content.
For example, when the multimedia data is a video course, the audio data is extracted from the corresponding video course, and the audio data and the video course are correspondingly consistent. Thus, full text of the audio data that is voice-text converted can be used as an index to the video lesson. Full text may be localized to a specific location of a video lesson in terms of words or sentences. In step S120, according to the matching between the current text content of the played audio data converted by the voice text and the full text, the specific position of the video course can be located by the position of the current text content in the full text, the video content after the specific position of the video course is used as the multimedia data to be played, and the video content after the specific position of the video course is played in step S130.
For example, when the multimedia data is a corresponding courseware, the courseware is generally used in a video course correspondingly, and therefore, the time stamp of the video course can be associated with the content of each page of the courseware (for example, the time of the first page of the courseware is 0:00-3:20, and the time of the second page of the courseware is 3:21-7: 10.). Thus, according to the above, the time stamp of the audio data and the time stamp of the video lesson are matched with each other, and therefore, the time stamp of the audio data is associated with each page of the courseware. In step S120, matching is performed according to the current text content of the played audio data and converted from the voice text with the text content in the courseware, after the visible page number is located, the page number of the courseware corresponding to the timestamp can be located, the current page number of the courseware and the courseware are taken as the multimedia data to be played, the current page number of the courseware is played through step S130, and the page number of the courseware is correspondingly switched along with the playing of the audio data.
For example, when the multimedia data is network-related data, in step S120, according to matching between the current text content of the played audio data and the text data in the network-related data (or subtitles of the video data in the network-related data, text data obtained by converting the voice text of the video data, and text data obtained by recognition in a picture), a position of the network-related data that matches the current text content can be located, and the position of the network-related data that matches the highlight can be used as the multimedia data to be played, and the position of the network-related data that matches the highlight is played in step S130.
In some embodiments of the present invention, the wake-up operation on the playback device includes operating a screen of the playback device or moving the playback device from a first state to a second state. As shown in fig. 2, fig. 2 is a schematic diagram of a wake-up playback device according to an embodiment of the present invention. The mobile phone 201 plays audio data in a sleep state (horizontal state), and the screen of the mobile phone 201 in the sleep state is displayed as a black screen 202. When the mobile phone 201 is lifted from the sleep state (horizontal state) to the second state (vertical state), the mobile phone 201 is awakened. After waking up the handset 201, the screen thereof displays the multimedia data 203 associated with the currently played content of the audio data. Fig. 2 only shows a wake-up mode of the playback device, and the present invention can also implement more variations, which are not described herein.
In some embodiments of the invention, the playback device includes at least a first screen and a second screen. In other words, the playback device may be a folding screen mobile phone, where the first screen and the second screen may be displayed in a folded or combined screen manner. The first screen and the second screen may be connected by a flexible display screen.
In a specific implementation of the foregoing embodiment, the first screen is in an awake state, the waking operation on the playback device is a waking operation on a second screen of the playback device, and the determined multimedia data to be played is played on the second screen of the playback device. This particular implementation is illustrated in fig. 3 and 4. Fig. 3 is a diagram illustrating a playback device having a first screen and a second screen, the second screen being in a sleep state according to an embodiment of the present invention. FIG. 4 is a diagram illustrating waking up a second screen according to an embodiment of the present invention. The playback device in fig. 3 is a mobile phone 210 with a foldable screen. The mobile phone 210 includes a first screen 211 and a second screen 212. The user plays the audio data through the mobile phone 210, and performs operations other than playing the audio data on the first screen 211, such as chatting, shopping, etc., and the second screen 212 is in a dormant state. When the user wants to acquire the associated multimedia data of the currently played audio data, the second screen 212 is woken up and the multimedia data is displayed on the second screen 212. Further, in the embodiments shown in fig. 3 and 4, both the first screen 211 and the second screen 212 are in the on-screen state, and waking up the second screen 212 may include touching the second screen 212 or pressing a physical key that wakes up the second screen 212. In a variation of the above embodiment, the first screen 211 and the second screen 212 are folded, the user plays the audio data through the mobile phone 210, and performs operations other than playing the audio data on the first screen 211, such as chatting, shopping, etc., and the second screen 212 is folded on the back of the first screen 211 (or folded in other ways) and is in a dormant state. When the second screen 212 is switched from the folded state to the screen-closed state, the second screen 212 is wakened up, so that the associated multimedia data is displayed after the second screen 212 is wakened up. The folded state and the screen-closed state can be detected by sensors disposed on the first screen 211 and the second screen 212.
Therefore, through the two screens, when a user conducts operations such as chatting and shopping on one screen, which are unrelated to audio playing, the user can wake up the other screen without exiting the current operation, so that the playing of the multimedia data related to the audio data is realized, the operation flow of the user is reduced, the user can conveniently conduct multi-process operation on the same device, and the user experience is further improved.
In other embodiments where the playback device includes at least a first screen and a second screen, the first screen and the second screen may be woken up simultaneously. Referring to fig. 5 and 6, fig. 5 is a flowchart illustrating playing multimedia data on a first screen and a second screen according to an embodiment of the present invention; fig. 6 is a diagram illustrating the playing of multimedia data on a first screen and a second screen according to an embodiment of the present invention.
Fig. 5 shows the following steps:
step S301: determining first multimedia data to be played according to first multimedia data related to the audio data played by the current playing information;
step S302: determining second multimedia data to be played according to second multimedia data related to the audio data played by the current playing information;
step S303: and respectively playing the determined first multimedia data to be played and the second multimedia data to be played on a first screen and a second screen of the playing equipment.
Wherein, step S301 and step S302 can be executed synchronously or in reverse order. Step S301 and step S302 may be performed in step S120 shown in fig. 1. Step S303 may be performed in step S130.
In particular, in some implementations of the invention, the first multimedia data may be, for example, courseware, and the second multimedia data may be, for example, lesson video; the first multimedia data may be, for example, courseware, and the second multimedia data may be, for example, network-associated data; the first multimedia data may be, for example, a lesson video, and the second multimedia data may be, for example, network-associated data; the first multimedia data may be, for example, one network associated data and the second multimedia data may be, for example, another network associated data. In the above examples, the first multimedia data and the second multimedia data are interchangeable, and the invention is not limited thereto.
As shown in fig. 6, the mobile phone 210 plays audio data and is initially in a sleep state, and when the mobile phone is woken up, the first multimedia data (courseware) is played on the first screen 211 of the mobile phone 210 and the second multimedia data (lesson video) is played on the second screen 212. Therefore, the multi-screen playing equipment is used for simultaneously playing the plurality of associated multimedia data, and the user is further assisted to understand the currently played audio content.
In some implementations of the foregoing embodiment of the present invention, the current playing information includes a current timestamp of the played audio data and a current text content of the played audio data converted by a speech text, and the first multimedia data to be played is determined from first multimedia data associated with the played audio data according to the current timestamp; and the two multimedia data to be played are determined according to the second multimedia data related to the self-played audio data of the current text content.
For example, when the first multimedia data is a course video and the second multimedia data is network-related data, the first multimedia data to be played is determined from the course video associated with the played audio data according to the current timestamp; and the second multimedia data to be played is determined according to the network related data associated with the audio data self-played by the current text content. When the first multimedia data is courseware and the second multimedia data is network related data, the first multimedia data to be played is determined according to the courseware related to the audio data played by the current timestamp; and the second multimedia data to be played is determined according to the network related data associated with the audio data self-played by the current text content. When the first multimedia data is a courseware and the second multimedia data is a course video, the first multimedia data to be played is determined according to the courseware related to the audio data played by the current timestamp; and determining the second multimedia data to be played according to the course video associated with the self-played audio data of the current text content. The specific manner for positioning the multimedia data to be played according to different current playing information and different multimedia data has been described above, and is not described herein again.
Referring now to fig. 7, fig. 7 is a flow chart illustrating the linked update of the multimedia data played by the first screen and the second screen according to an embodiment of the present invention. Fig. 7 shows a specific implementation of the step of playing the determined first multimedia data to be played and the determined second multimedia data to be played on the first screen and the second screen of the playing device, respectively. Fig. 7 shows the following steps:
step S311: establishing association of the first multimedia data and the second multimedia data according to the current timestamp and/or the current text content;
step S312: updating the multimedia data displayed on one screen in response to the operation on the screen;
step S313: and updating the multimedia data displayed on the other screen in a linkage manner according to the association of the first multimedia data and the second multimedia data.
In this embodiment, the display contents of the first screen and the second screen are updated in real time according to the playing of the audio data without the operation of the user. When a user operates one of the screens (for example, through gesture touch operation), the playing content of the one of the screens is updated. For the curriculum video, the updating comprises fast forwarding, rewinding, positioning to a specific time stamp and the like; for the courseware, the updating comprises page turning backwards, page turning forwards, page number positioning and the like; for the network associated data, the updating comprises pulling up, pulling down, positioning to a specific display position and the like.
