Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a block diagram illustrating an exemplary system 100 for playing multimedia according to an exemplary embodiment of the present invention.
Referring to fig. 1, the system 100 may include a smart phone 101 and a smart tv 102 and a plurality of dedicated audio output devices 103, 104 and 105 (such as, for example, a stereo, a speaker, and a headphone, etc.), and these electronic devices may be interconnected or interconnected with each other through an internet of things (IOT) such as, but not limited to, that shown in fig. 1, so that the smart phone 101 and the smart tv 102 having computing processing capability may each be connected to the plurality of dedicated audio output devices 103, 104 and 105 shown in fig. 1 through the IOT.
In the example disclosed herein, the smart phone 101 and the smart tv 102 may each load and run various client applications or APPs for playing multimedia content (such as text, data, graphics, images, animations, sounds, etc.), and may each be configured to select a target audio output device suitable for use in a current scene from among the connected plurality of dedicated audio output devices 103, 104, and 105 and the audio output devices of the smart phone 101 and the smart tv 102 themselves in response to a play instruction for the multimedia content, so as to synchronously play audio data of the multimedia content through the selected target audio output device during playing video data of the multimedia content. In addition, the smartphone 101 may also synchronously play audio data of the multimedia content through the selected target audio output device during the process of projecting the video data of the multimedia content to the screen of the smart television 102 for display. In this way, the electronic devices (such as the smart phone 101 and the smart television 102 shown in fig. 1) will no longer be limited to outputting sound using their own audio output functions, but can output sound using the appropriate audio output functions of other electronic devices according to the current playing scene. The method not only promotes the interconnection and the interoperability among the electronic equipment, but also makes full use of hardware resources of the audio output function of the electronic equipment, thereby further improving the listening experience of users to the multimedia content.
The playing process of the multimedia will be described in detail below with reference to fig. 2.
Fig. 2 is an exemplary process 200 illustrating a method for playing multimedia according to an exemplary embodiment of the present invention. The process 200 may be performed on any terminal device with computing processing capabilities, such as the smart phone 101 and smart television 102 shown in fig. 1 or other intelligent electronic devices.
Referring to fig. 2, in block S210, the process 200 may acquire information related to a current scene in response to a play instruction for multimedia content.
Here, the information related to the current scene may include information such as, but not limited to, the number of persons (e.g., headcount) present in the current scene; the type of person in the current scene (e.g., elderly, children); the behavior of the person in the current scene (e.g., the elderly are sleeping, the children are learning); and a distance between a person viewing the multimedia content in the current scene and a screen on which video data of the multimedia content is presented, and the like. After receiving a play instruction for the multimedia content, the process 200 may capture the above information through a camera connected to the IOT.
Next, in block S220, the process 200 may determine a target audio output device from the connected plurality of audio output devices that is suitable for use in the current scene.
The determination process of the above-described target audio output device will be described in further detail below with reference to specific examples.
In this example, the process 200 may identify a target audio output device suitable for use in the current scene from among the plurality of connected audio output devices using an audio device scene model within which audio output devices associated with the respective scenes are preset (i.e., audio output devices used in the respective scenes). Specifically, the process 200 may compare the information related to the current scene previously obtained in block S210 with the scene features of each scene preset in the scene model of the audio device one by one; if a scene matching the acquired information related to the current scene exists, acquiring an audio output device associated with the matched scene; a target audio output device that is the same or similar to the audio output device's performance parameters (such as, but not limited to, volume output capabilities) and/or device type (e.g., headphones, stereo, etc.) is then located from the connected audio output devices.
In this example, the audio device scene model may identify a plurality of target audio output devices, in which case the process 200 may transmit audio data of the multimedia content to a highest priority target audio output device of the plurality of target audio output devices. Heretofore, the process 200 may determine a priority for each target audio output device based on factors such as, but not limited to, the volume output capabilities of the target audio output device, the distance between the target audio output device and the person viewing the multimedia content in the current scene, the time at which the multimedia content was played, and the program type of the multimedia content.
The determination process of the priority of the above-described target audio output device will be described in further detail below with reference to fig. 3, 4, and 5.
FIG. 3 shows a schematic diagram 300 of recommending a target audio output device based on the time at which multimedia content is played and the volume output capability of the target audio output device, according to an illustrative embodiment of the invention.
As shown in fig. 3, the left and right ends of the horizontal axis respectively represent ordinary time (for example, 9 pm before) and working time (or sleeping time), and the upper and lower ends of the vertical axis respectively represent weekends and non-weekends. The entire coordinate system can be divided into four regions, which are: a first quadrant 301, a second quadrant 302, a third quadrant 303, and a fourth quadrant 304.
In the example shown in fig. 3, when the time of playing the multimedia content falls within the first quadrant 301 (i.e., when the time of playing the multimedia content is weekend hours of operation or sleeping hours), the process 200 may preferentially (or defaults to) recommend a target audio output device with a moderate volume, and accordingly, among the identified plurality of target audio output devices suitable for use in the current scene, the target audio output device with a moderate volume has a higher priority and the target audio output device with a smaller or larger volume has a lower priority; when the time to play the multimedia content falls within the second quadrant 302 (i.e., when the time to play the multimedia content is a common time on a weekend), the process 200 may preferentially recommend a target audio output device with a higher volume, and accordingly, among the identified plurality of target audio output devices suitable for use in the current scene, the target audio output device with a higher volume has a higher priority and the target audio output device with a lower or moderate volume has a lower priority; when the time to play the multimedia content falls within the third quadrant 303 (i.e., when the time to play the multimedia content is a normal time other than weekends), the process 200 may preferentially recommend a target audio output device with a moderate volume, and accordingly, among the identified plurality of target audio output devices suitable for use in the current scene, the target audio output device with a moderate volume has a higher priority and the target audio output device with a smaller or larger volume has a lower priority; when the time to play the multimedia content falls within the fourth quadrant 304 (e.g., when the time to play the multimedia content is non-weekend hours of operation or sleeping hours), the process 200 may preferentially recommend a target audio output device with a lower volume, and accordingly, among the identified plurality of target audio output devices suitable for use in the current scene, the target audio output device with a lower volume has a higher priority and the target audio output device with a medium or higher volume has a lower priority.
Fig. 4 shows a schematic diagram 400 of recommending a target audio output device based on a program type of multimedia content and a volume output capability of the target audio output device according to an exemplary embodiment of the present invention.
As shown in fig. 4, the horizontal axis represents the volume of the audio output device, and the volume gradually decreases from left to right on the horizontal axis. The entire horizontal axis can be divided into three intervals, which are: a first section 401, a second section 402, and a third section 403, wherein the first section 401 corresponds to a target audio output device with a large volume, the second section 402 corresponds to a target audio output device with a medium volume, and the third section 403 corresponds to a target audio output device with a small volume.
In the example shown in fig. 4, when the program type of the multimedia content belongs to a large event, evening or movie, the process 200 may preferentially (or defaultly) recommend a target audio output device with a larger volume, and accordingly, among the identified plurality of target audio output devices suitable for use in the current scene, the target audio output device with a larger volume has a higher priority and the target audio output device with a medium or smaller volume has a lower priority; when the program type of the multimedia content belongs to a general tv show or program, the process 200 may preferentially recommend a target audio output device with a moderate volume, and accordingly, among the identified plurality of target audio output devices suitable for use in the current scene, the target audio output device with a moderate volume has a higher priority and the target audio output device with a larger or smaller volume has a lower priority; when the program type of the multimedia content belongs to a children program, the process 200 may preferentially recommend a target audio output device with a smaller volume, and accordingly, among the plurality of target audio output devices identified as being suitable for use in the current scene, the target audio output device with a smaller volume has a higher priority, and the target audio output device with a medium or larger volume has a lower priority.
Fig. 5 shows a schematic diagram 500 for recommending a target audio output device based on the time at which multimedia content is played, the program type of the multimedia content, and the volume output capability of the target audio output device, according to an exemplary embodiment of the present invention.
In the example shown in fig. 5, the time 501 of playing the multimedia content is a common time of weekend (e.g., around 10 am), the program type of the multimedia content 502 is a big event (soccer), and the process 200 may preferentially recommend a target audio output device with a larger volume to the user based on the recommendation principle as described above with reference to fig. 3 and 4, accordingly, among the identified target audio output devices suitable for use in the current scene, the target audio output device with a larger volume has a higher priority and the target audio output device with a medium or small volume has a lower priority.
In addition to the above recommendation example, the process 200 may recommend target audio output devices based on assigning weights for different influencing factors. As a non-limiting example, the process 200 may also determine a priority of the target audio output device for each factor, and assign a weight to the priority of the target audio output device determined for each factor according to the influence of each factor on the priority of the target audio output device, and then determine the priority of the target audio output device based on the priority of the target audio output device determined for each factor to which the weight is assigned. This allows the priority of each target audio output device to be determined by:
the priority of each target audio output device is time of playing the multimedia content × weight 1+ program type of the multimedia content × weight 2+ … ….
Regarding the determination of the weight, it may be determined as the case may be, for example, a weight 1 of the time corresponding to playing the multimedia content may be greater than a weight 2 of the program type corresponding to the multimedia content, and the present invention is not limited thereto.
In general, the process 200 may directly transfer audio data to an optimal target audio output device (i.e., the highest priority target audio output device), but considering that the optimal target audio output device (i.e., the highest priority target audio output device) is not necessarily the audio output device desired by the user, the process may also present a plurality of target audio output devices to the user in a list form (e.g., pop-up box) in order of priority from high to low for selection by the user. Accordingly, the process 200 may transmit audio data of the multimedia content to a target audio output device selected by the user from the list. In addition, the user can use the audio output device expected by the user according to the actual needs without adopting the recommendation result.
In addition, for a target audio output device selected by the user each time, the process 200 may further associate the current scene with the selected target audio output device, and learn the association as historical data into the audio device scene model, so that the audio device scene model performs self-learning on the result of the selection, so as to recommend a target audio output device meeting the user's expectations to the user for a similar scene in the future, thereby improving the recognition accuracy of the audio device scene model. For example, the process 200 may preferentially recommend an audio output device previously selected by the user when a similar scene is next encountered.
Finally, in block S230, the process 200 may play audio data synchronously through the target audio output device during the playing of the video data of the multimedia content.
As a non-limiting example, the process 200 may perform audio/video encoding and decoding on the multimedia content from a starting point of playing in the same terminal device, and the video data and the audio data obtained thereby may be respectively transmitted to the corresponding display device and the recommended audio output device, so as to ensure synchronous playing of audio/video of the multimedia content.
It can be seen that the implementation process of the present invention enables an electronic device (such as a smart television, a smart phone, etc.) to output sound using its own audio output function, but output sound using an appropriate audio output function of another electronic device according to the current playing scene. The method not only promotes the interconnection and the interoperability among the electronic equipment, but also makes full use of hardware resources of the audio output function of the electronic equipment, and further improves the listening experience of users to the multimedia content.
