Moreover, the term “processor” or “controller” also refers to other hardware capable of performing such functions and/or executing software, such as the example hardware recited above.
As those skilled in the art will appreciate, the term “media content” as used herein refers to any data or signal that is able to convey information and ideas in various forms. Examples of such media content include, but are not limited to, audio data or content, image data or content, video data or content, audiovisual data or content and multimedia content. The term “mobile device” as used herein refers to any portable device which is able to play back media content to an end user.
Examples of such mobile devices include, but are not limited to, mobile phones, smartphones, media players, laptops, tablets, netbooks and personal digital assistants.
As illustrated, initially, the playback of the media content on the mobile device is detected at step s110. The media content played back by the mobile device may be or include audio content, and the vehicle may be provided with a microphone that is arranged to detect if the audio content has a level higher than the ambient noise level. If so, it is detected that the media content is being played back on the mobile device.
Then, at step s120, the media content played back on the mobile device is retrieved. In an embodiment, step s120 may comprise step s121 and s122 as illustrated in
In an embodiment, step s121 may be implemented by using a digital watermark embedded in the media content captured by the microphone of the vehicle. Specifically, according to the watermark embedded in the captured media content, it is possible for the vehicle to identify the media content that is being played back by the mobile device and also to identify the source of the media content (for example, a cloud service such as Spotify, Podcast or the like).
Additionally or alternatively, the vehicle may identify the source of the media content played back on the mobile device, through information sharing between the mobile device and the vehicle which is enabled by a pairing process therebetween.
In another embodiment, step 120 may comprise step s121′ and s122′ as illustrated in
In an embodiment, step s121′ may be implemented by identifying the content source of the media content played back on the mobile device and then acquiring the media content playlist from the content source. Then, at step s122′, the media content listed by the media content playlist is retrieved from the identified content source. Alternatively, in case the media content playlist and the listed media content are stored in the user's cloud drive, it is possible to acquire the media content playlist and retrieve the listed media content from the cloud drive. In case a pairing process has been performed between the mobile device and the vehicle, the vehicle can directly acquire the media content playlist as shared information between the mobile device and the vehicle.
Referring back to
After step s130, a first message instructing the mobile device to pause its playback of the media content is sent to the mobile device at step s140.
As such, the playback of the media content can be automatically and seamlessly taken over by his car, as soon as the user who enjoys the media content using his mobile device enters the car. Accordingly, uninterrupted playback of the media content can be achieved and meanwhile the limited battery power of the mobile device can be saved.
As illustrated in
As such, the playback of the media content can be automatically and seamlessly transferred back to the user's mobile device from his car, when he arrives at the predefined destination. Accordingly, the user can get out of the car while enjoying the media content uninterruptedly.
Alternatively, if it is detected that the vehicle arrives at a predefined destination at step s140, a third message inquiring whether a user of the mobile device wants to transfer the playback of the media content from the vehicle to the mobile device may be sent to the mobile device at step s150, as illustrated in
Correspondingly to the method 100 for transferring playback of media content between a mobile device and a vehicle described above with reference to
Referring to
In an embodiment, after step s220, the method 200 may proceed to step s250, at which a second message instructing the mobile device to resume its playback of the media content is received from the vehicle. Then, at step s260, a resume point is fetched as a position within the media content, which the playback of the media content by the vehicle reaches when the vehicle sends the second message. In practical implementation, the resume point may be included in the second message sent by the vehicle or it can be derived from a frame count or a timestamp, which can be used to achieve synchronous playback of the media content at the mobile device and the vehicle as described above. Alternatively, the resume point may be fetched from the source of the media content (for example, a cloud service such as Spotify, Podcast or the like). Next, the playback of the media content on the mobile device is resumed from the resume point at step s270.
Optionally, after step s220 and before step s250, the method 200 may proceed to step s230, at which a third message inquiring whether a user of the mobile device wants to transfer the playback of the media content from the vehicle to the mobile device is received from the vehicle. Then, at step s240, a fourth message indicating whether the user wants to transfer the playback of the media content from the vehicle to the mobile device as a response to the third message is sent to the vehicle. The second message is received from the mobile device if the fourth message indicates that the user wants to transfer the playback of the media content from the vehicle to the mobile device.
To facilitate a better understanding of the proposed solutions,
As illustrated, at step s910, the vehicle detects the playback of media content on the mobile device and identifies the content source of the media content as the cloud service such as Spotify, Podcast or the like. Then, the vehicle establishes a link to the content source at step s920 and retrieves the media content from the content source at step s930. Next, the vehicle plays back the retrieved media content at the vehicle in synchronization with the playback of the media content on the mobile device at step s940, and sends to the mobile device a first message instructing the mobile device to pause its playback of the media content at step s950. Upon receipt of the first message, the mobile device pauses its playback of the media content at step s960.
As illustrated, at step s1010, the vehicle detects the playback of media content on the mobile device and acquires a media content playlist from the mobile device as shared information between the mobile device and the vehicle. Then, the vehicle retrieves media content listed by the playlist from a content source at step s930. Next, the vehicle plays back the retrieved media content at the vehicle in synchronization with the playback of the media content on the mobile device at step s1030, and sends to the mobile device a first message instructing the mobile device to pause its playback of the media content at step s1040. Upon receipt of the first message, the mobile device pauses its playback of the media content at step s1050.
As illustrated, at step s1110, it is detected that the vehicle arrives at a predefined destination. Then, at step s1120, the vehicle sends to the mobile device a third message inquiring whether a user of the mobile device wants to transfer the playback of the media content from the vehicle to the mobile device. In response to the third message, the mobile device sends to the vehicle a fourth message indicating whether the user wants to transfer the playback of the media content from the vehicle to the mobile device, at step s1130. If the fourth message indicates that the user wants to transfer the playback of the media content from the vehicle to the mobile device, the vehicle sends to the mobile device a second message instructing the mobile device to resume its playback of the media content at step s1140. Upon receipt of the second message, the mobile device fetches from the source of the media content a resume point as a position within the media content, which the playback of the media content by the vehicle reaches when the vehicle sends the second message, at step s1150. Next, the mobile device resumes the playback of the media content on the mobile device from the resume point at step s1160, and the vehicle ends its playback of the media content at step s1170.
