Title:
STREAM SYNCHRONIZATION
Document Type and Number:
WIPO Patent Application WO/2018/089352
Kind Code:
A3
Abstract:
Methods and systems for synchronizing audio streams. The method includes tagging a first presentation time to a frame buffer of a first audio stream and a second presentation time to a frame buffer of a second audio stream. The second audio stream is to be synchronized to the first audio stream. The method also includes aligning the second presentation time of the frame buffer of the second audio stream with the first presentation time of the frame buffer of the first audio stream, resampling the second audio stream so that each resampling point of the second stream is aligned with a corresponding sampling point in the first audio stream, and determining sample data for each resampling point of the second audio stream.
