Benefits of technology

The patent text states that there may be slight differences in the times when two media players are playing due to factors like sound speed and processing times. These differences can be on the order of tens of milliseconds and are not noticeable to the human ear. The text explains that these differences can be reduced or eliminated by cross-correlating the audio outputs of the players and automatically adjusting some of them forward or backward to maximize the cross-correlations. Alternatively, the players can be adjusted manually to minimize the differences.

Problems solved by technology

Such music players, unless connected to an amplifier, have an anti-social nature to them.

Embodiment Construction

[0027]Aspects of the present invention relate to two or more users who each have media players, and would like to enjoy a piece of media content together in unison.

In the case of related multimedia files, the media players play the multimedia files together in concert. A multimedia file may include a song, a movie, a video clip, a slide show, or such other content.

[0028]There are several different usage scenarios that arise in synchronization of playback of media players. In some scenarios, the multimedia file to be played is known a priori by each media player. In other scenarios, the multimedia file to be played is not known a priori by each media player, and has to be identified. In some scenarios, each multimedia player begins its playback fr...
