Systems and Methods for Syncronizing Multiple Electronic Devices
First Claim
1. An audio playback device comprising:
- a communication component adapted to connect the audio playback device to a slave device via a wireless connection;
an audio output component adapted to output audio; and
a controller module configured to interface with the communication component and the audio output component, and further configured to;
send a request to the slave device including a first system time via the wireless connection,receive a response from the slave device via the wireless connection at a second system time,calculate a one-way network latency time value for the slave device based on the first system time and the second system time,send the one-way network latency time value to the slave device for calculation of a system clock offset value,establish an audio playback session with the slave device via the wireless connection, the audio playback session using a data socket of the slave device,send, using the audio playback session, at least a portion of an audio file to the slave device and a playback timing instruction indicating a current system time, the audio file for playback on the slave device according to the playback timing instruction and the system clock offset value, andinitiate playback of the audio file from the audio output component.

Abstract
Embodiments are provided for syncing multiple electronic devices for collective audio playback. According to certain aspects, a master device connects (218) to a slave device via a wireless connection. The master device calculates (224) a network latency via a series of network latency pings with the slave device and sends (225) the network latency to the slave device. Further, the master devices sends (232) a portion of an audio file as well as a timing instruction including a system time to the slave device. The master device initiates (234) playback of the portion of the audio file and the slave devices initiates (236) playback of the portion of the audio file according to the timing instruction and a calculated system clock offset value.
