Abstract
Devices and methods are disclosed for managing an output of an output stream. One embodiment relates to a method of tracking an output of an A/V decoder. In this embodiment, indication of an output stream time reference and a location of at least one output sample are received. The received time reference is compared to the output sample and the output sample rate of the A/V decoder is adjusted.
Claims25
A method of tracking an output of an A/V decoder comprising:
- (a) receiving an indication of an input stream time reference signal;
- (b) receiving a location of at least one output sample;
- (c) comparing said time reference signal to said output sample location;
- and
- (d) adjusting an output sample rate of the A/V decoder, wherein adjusting further comprises receiving at least one next sample request signal.
A method of tracking an output of an A/V decoder comprising:
- (a) receiving an indication of an input stream system time reference signal;
- (b) receiving a location of a current output sample;
- (c) determining if said current output sample location leads or lags said system time reference signal;
- (d) decimating output samples if said current output sample location leads said system time reference signal;
- and
- (e) interpolating output samples if said current output sample location lags said system time reference signal.
A rate managed output device adapted to manage a rate of an output of an A/V decoder, wherein said rate managed output device is adapted to receive at least an indication of an input stream time reference signal;
- receive a location of at least one output sample, compare said time reference signal to said output sample location;
- adjust an output sample rate of said A/V decoder, and receive at least one next sample request signal as feedback.
