Problems solved by technology

However, mobile device performance may occasionally degrade due to a weakened battery and / or network connection
Additionally, remaining dependent on a mobile device may cause the user to sacrifice utilization for better sound quality (e.g., by pairing with better speakers), social integration (e.g., by pairing speakers instead of headphones), and / or playback stability (e.g., Battery) associated with another music player device
Although the user always has the option to actively switch player devices, this itself may cause interruptions in playback during the switch and may lose playback position within the audio set

Embodiment 1

[0135] A user can initiate playback of a playlist on the wearable device. Both the playlist and the songs within the playlist can be stored in the cloud. The wearable device accesses the cloud and then starts streaming songs from the playlist to the wireless freestanding speaker. The wearable sends a broadcast signal to detect other devices. A nearby tablet that is powered on can receive the signal and respond based on its attributes (eg, it is a tablet and has AC power). A rule may indicate that playback will be diverted to any responding device with AC power. The wearable device can thus determine that playback will be transferred to the tablet. The wearable device can send a playback transfer communication to the tablet, thereby identifying the playlist, position within the playlist, takeover time, and volume setting. The tablet can then start playing at that location at the takeover time. It can adjust its volume setting appropriately so that the volume of the song pl...

Embodiment 2

[0138] After Example 1, the tablet can start to move and get closer to the edge of the effective distance of the speaker. The tablet can detect a weakening of the connection and / or motion, and can send an alert to the wearable device that is about to move out of the effective distance of the speaker (eg, because the wearable device is the master device or the device that initiated the playback). The alert identifies the position within the playlist and the most recent play transfer time. Once the most recent playback transition time is reached, the tablet can stop playback and the wearable can then begin streaming music to the wireless speaker corresponding to the location in the playlist.

Embodiment 3

[0140]After Example 1, the wearable device can start to move and gradually approach the edge of the effective distance of the speaker. The wearable device can detect a weakening of the connection and / or motion, and can send an alert to the tablet that is about to move out of the effective distance of the speaker (eg, because the tablet is a player device). An alert may be presented on one or both of the wearable device and the tablet indicating that playback will continue using the tablet (unless an objection is received). If no objection is received, the tablet may continue its playback. The wearable device can then stop accepting input regarding playback.

Abstract

The present invention discloses a method of facilitating a smooth listening experience during which a user can enjoy continuous music playback despite moving between settings or using a device with limited playback capabilities. While the first player device is playing a song from the audio collection, one or more other devices may be evaluated to determine whether one device should take over the playback. This determination may be made by comparatively evaluating attributes of the other device such as its power source, battery level (if applicable), network connection, access to songs, and / or device type. If it is determined that the playback is to be transferred between devices, a message may be sent to the new player device indicating when playback starts and which song to play. The first player device may stop playing substantially at the same time that the new player device starts playing.

Description

Background technique [0001] The present disclosure relates generally to automated coordination between electronic devices, and in particular to smoothly and automatically switching playback of music collections between devices. [0002] Electronic devices have transformed how easily people listen to music. Years ago, bulky players and physical media were required to play recorded songs. Songs can now be played from mobile devices without using physical media. Thus, users of these devices can enjoy music while moving from one place to another. However, music playback may be interrupted due to a drained device battery or due to a weakened network connection. [0003] Many mobile devices can play music, allowing users to enjoy music while walking around. However, the performance of a mobile device may occasionally degrade due to a weakened battery and / or network connection. Additionally, remaining dependent on a mobile device may cause the user to sacrifice utilization for b...
