Audio player device for synchronous playback of audio signals with a compatible device
View Patent ↗The present invention discloses a method, system and apparatus for playing an audio signal synchronously on a first mobile audio player and at least a second mobile audio player. More particularly, the invention pertains to an audio player device enabled for wireless transmission and reception of an audio signal. In one aspect, a delay enables the audio signal to be played synchronously on the audio player with a second audio player. In another aspect synchronization signals are used to play the audio signal synchronously on the first audio player and the second audio player.
1. A method comprising:
receiving, at a first receiving media player device, a broadcast of a select media content from a broadcasting media player device via a first wireless communication channel;
re-broadcasting the select media content from the first receiving media player device to at least one additional receiving media player device via a second wireless communication channel; and
effecting playback of the select media content at the first receiving media player device such that playback of the select media content at the first receiving media player device is substantially synchronized with playback of the select media content at the broadcasting media player device and the at least one additional receiving media player device.
2. The method of claim 1 wherein the at least one additional receiving media player device is unable to receive the broadcast of the select media content from the broadcasting media player device via the first wireless communication channel.
3. The method of claim 1 wherein the first wireless communication channel is a local wireless communication channel and the at least one additional receiving media player device is outside a local wireless communication range of the broadcasting media player device.
4. The method of claim 1 wherein effecting playback of the select media content at the first receiving media player device comprises delaying playback of the select media content at the first receiving media player device by an amount of time needed to substantially synchronize playback of the select media content at the first receiving media player device with playback of the select media content at the at least one additional receiving media player device.
5. The method of claim 4 wherein playback of the select media content is delayed at the first receiving media player device based on the equation:
delay_time= D· ( N max - N ),
wherein “delay_time” is an amount of delay, “D” is a predetermined amount of delay per hop, “N max ” is a maximum number of hops between the broadcasting media player device and any receiving media player device for which synchronized playback of the select media content is desired, and “N” is a number of hops between the broadcasting media player device and the first receiving media player device.
6. The method of claim 4 wherein playback of the select media content at the broadcasting media player device is delayed by an amount of time needed to substantially synchronize playback of the select media content at the broadcasting media player device with playback of the select media content at the first receiving media player device and the at least one additional receiving media player device.
7. The method of claim 1 wherein at least one of the first and second wireless communication channels is a communication channel selected from a group consisting of: a communication channel established via a local wireless network and a communication channel established via a mobile telecommunications network.
