METHOD AND APPARATUS FOR REDUCING LATENCY IN MULTI-MEDIA SYSTEM

摘要

A sink apparatus for receiving and playing back multimedia data receives data frames and discards data frames from its processing pipeline in order to reduce latency if it is determined that an amount of media data buffered in one or more portions of the processing pipeline during a fixed playback time period is above a threshold value. The threshold value and therefore the extent to which data frames are discarded can be varied in order to balance latency and quality of the displayed multimedia data.

1. A method for adjusting latency in a sink apparatus, wherein the sink apparatus receives media data from a source apparatus for playing back on a display and includes a processing pipeline, the method comprising:
monitoring an amount of media data buffered in at least a portion of the processing pipeline; comparing a monitored amount of media data with a predetermined threshold value; and if the monitored amount of media data exceeds the predetermined threshold value, discarding media data from the processing pipeline until the monitored amount falls below the predetermined threshold value.
