Media subsystem, method and computer program product for adaptive media buffering

Abstract

A media subsystem of a processing element includes a plurality of elements and a latency manager. The plurality of elements are capable of processing media data including a plurality of instances wherein a first element inserts a length of media data into buffer(s) from which a second element thereafter reads the length of media data for subsequent output from the media subsystem. The latency manager is capable of determining a latency requirement of the media subsystem, and then dynamically tuning the length of media data inserted into the buffer(s) based upon the latency requirement, including increasing or decreasing the length of media data inserted into the buffer(s) during one or more instances(s).

Description

Technical field [0001] The embodiments of the present invention generally relate to a system and method for optimizing media playback in a playback device, and more particularly to adaptive media buffering during media playback while reducing the power consumption of the playback device. System and method of replay. Background technique [0002] Audio processing is very time critical in nature. In many traditional audio playback systems, the audio subsystem reads data from the memory and generates audio sample blocks from the data, and simultaneously plays the previously generated blocks. If the processing or generation of a new block takes longer than a block is played out, a gap (called a "drop-out") may be heard in the audio playback. In order to avoid such loopholes, more than one generated block can be placed in the queue in the buffer for replay. [0003] The audio buffer between two independently running parts of the audio chain can be seen as a first-in first-out (FIFO) q...

Problems solved by technology

Common to all modes is that they usually have associated non-zero shutdown / power-up cycles, which makes use inefficient for very short sleep periods
