A method and apparatus for implementing the removal of electronic or acoustic echo from a full-duplex audio data stream. Audio data which has been input into a processing system is sampled at a predetermined rate. Audio data which has been received by the processing system and which is to be output from the processing system is also sampled. Each sample of the output audio data corresponds in time to the most recent sample of the input audio data and approximates the value of the output audio data at the time the most recent sample of the input audio data was acquired. A storage device is provided for storing N samples of the input audio data and N corresponding samples of the output audio data, where N is a positive integer. N samples of the input audio data and N corresponding samples of the output audio data are stored in the storage device, such that the contents of the storage device represent both the input audio data and an approximation of corresponding output audio data during a given time interval. This combined input/output can be routed through the processing system or across a communications network to another processing system, and the echo can be ignored or removed at any point by a cancellation device.

G06F 316

364514R

A real-time media driver for scheduling and mixing media in a multimedia environment. Implemented to operate in conjunction with a non-real-time operating system, the real-time media driver comprises a wave driver which controls a predominant percentage of the operations of the media hardware device and a mini-device driver which is software provided by the vendor of the media hardware device to support functions unique to the particular media hardware device. Furthermore, the real-time media driver comprises a media scheduler which (i) synchronizes multiple media streams prior to being input into a mixing/splitting device of the media scheduler; (ii) allows reconfiguration of attributes of media streams without loss of content prior to and after operations by the mixing/splitting device; and (iii) appropriately mixes media to produce multi-channel media according to a certain "prioritized sharing" policies.

39518401

A method for dynamically scaling consumption of processor cycles by a task executing in a computer system, wherein a performance task determines an error measure that indicates real-time errors logged by at least one driver executing in computer system. If the error measure exceeds a predetermined threshold, then the consumption of processor cycles by a high consumption task is reduced.
