Abstract:
1. A method comprising: receiving, by a multimedia processing device comprising a processor, a multimedia stream from a first source, the multimedia stream comprising a first video stream and a first audio stream; receiving, by the multimedia processing device, a second audio stream from a second source, the second audio stream differing from the first audio stream, wherein the multimedia stream and the second audio stream are associated with common subject matter; forwarding video content of the first video stream to a display device to display the video content; receiving, by the multimedia processing device, at a first time during the display of the video content at the display device, a first user action coincident with a visual aspect of an event observable in a presentation of the first video stream, wherein the event is common to the subject matter presented in both the first video stream and the second audio stream; forwarding audio content of the second audio stream to a speaker for presentation of the audio content; receiving, by the multimedia processing device, at a second time during presentation of the audio content at the speaker, a second user action coincident with an audible aspect of the event observable in a presentation of the second audio stream, wherein one of the first user action, the second user action, or the first and second user actions comprises pressing a button; determining, by the multimedia processing device, in real-time, a timing offset between the first video stream and the second audio stream according to a time difference between the first time and the second time; transmitting, by the multimedia processing device, first information while receiving the multimedia stream to display images associated with the first video stream; and transmitting, by the multimedia processing device, second information while receiving the second audio stream to present audible signals associated with the second audio stream, wherein transmitting of the first information and the second information is synchronized according to the timing offset.
