PROVIDING AUDIO AND ALTERNATE AUDIO SIMULTANEOUSLY DURING A SHARED MULTIMEDIA PRESENTATION

摘要

Aspects of the subject disclosure may include, for example, decoding first and second encoded audio portions extracted from a digitally encoded data stream to obtain first and second decoded audio portions. The digitally encoded data stream includes an encoded video portion, multiple encoded audio portions including the first and second audio portions and a reference marker. The first and second decoded audio portions are synchronized to a decoded video portion based on the reference marker. The first decoded audio portion is forwarded to equipment of a first user and the second decoded audio portion is forwarded to equipment of a second user. Presentations of the first decoded audio portion by the equipment of the first user and the second decoded audio portion by the equipment of the second user are synchronized to a presentation of the decoded video portion. Other embodiments are disclosed.

主权项

1. A method comprising:
receiving, by a system including a processor, a digitally encoded data stream comprising an encoded video data portion, a plurality of encoded audio data portions, and a synchronization marker; extracting, by the system, from the digitally encoded data stream, a first encoded audio data portion; decoding, by the system, the first encoded audio data portion to obtain a first decoded audio portion; extracting, by the system, from the digitally encoded data stream, a second encoded audio data portion; decoding, by the system, the second encoded audio data portion to obtain a second decoded audio portion, wherein the first decoded audio portion and the second decoded audio portion are synchronized to a decoded video portion obtained from the encoded video data portion based on the synchronization marker; forwarding, by the system, the first decoded audio portion to equipment of a first user, wherein presentation of the first decoded audio portion by the equipment of the first user is synchronized to a presentation of the decoded video portion; and forwarding, by the system, the second decoded audio portion to equipment of a second user, wherein presentation of the second decoded audio portion by the equipment of the second user is synchronized to the presentation of the decoded video portion.
