Described herein is a technology facilitating circumvention of dynamic and robust detection of one or more embedded-signals (e.g., watermark, copyright notice, encoded data, etc.) in one or more input carrier signals (e.g., multimedia stream, video stream, audio stream, data, radio, etc.).

Circumvention of dynamic, robust, embedded-signal detection

Described herein is a technology facilitating circumvention of dynamic and robust detection of one or more embedded-signals (e.g., watermark, copyright notice, encoded data, etc.) in one or more input carrier signals (e.g., multimedia stream, video stream, audio stream, data, radio, etc.). This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

A system and method for generating a list is provided. The system includes a seed item input subsystem, an item identifying subsystem, a descriptive metadata similarity determining subsystem and a list generating subsystem that builds a list based, at least in part, on similarity processing performed on seed item descriptive metadata and user item descriptive metadata and user selected thresholds applied to such similarity processing. The method includes inexact matching between identifying metadata associated with new user items and identifying metadata stored in a reference metadata database. The method further includes subjecting candidate user items to similarity processing, where the degree to which the candidate user items are similar to the seed item is determined, and placing user items in a list of items based on user selected preferences for (dis)similarity between items in the list and the seed item.

An operating system has an audio system service that can capture all of the streaming audio destined for an output device and make it available for processing. An application can perform the processing upon the captured streaming audio. Any streaming audio that is output by the application and destined for a render device can also be captured for signal processing prior to being mixed with other streaming audio destined for the output device.

Access to audio output via capture service

Described herein is a technology for dynamic and robust detection of one or more embedded-signals (e.g., watermark, copyright notice, encoded data, etc.) in an input signal (e.g., multimedia stream, video stream, audio stream, data, radio, etc.) within a multi-signal environment. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

Centralized detector of dynamic, robust, embedded-signals

A sample rate converter (SRC) is used to slave hardware devices to a master hardware device. A clock manager registers the time at each clock of each device, communicates with memory that stores the clock times, and reports correlations between each clock time and the time at a reference clock. The processing of a data stream can be slaved to one or more hardware devices. The processing of a wake up period can be slaved to the clock of the master hardware device by adjusting the wakeup period. Slaving of hardware devices to the master hardware device can also be accomplished by finding a correlation between the clock times in memory and the reference clock. Each correlation can be input into an SRC corresponding to each slave hardware device. Each SRC can then generate or consume a data stream at the actual rate of the corresponding slave hardware device.

Synchronization with hardware utilizing software clock slaving via a clock

A system and methods for automated DSP processing of media entities to create a persistent data store having DSP processed media entities is provided. In connection with a system that convergently merges perceptual and digital signal processing analysis of media entities for purposes of classifying the media entities, various means are provided to automatically DSP process media entities data for storage in persistent data store. Techniques for incorporating DSP processed media entity data into a music matching and analysis system are also included. In an illustrative implementation, the DSP processed media entity data may be generated and stored for leveraging to participating users.

System and methods for automatic DSP processing

An operating system is logically separated into a partition for a kernel and a partition for an audio subsystem having logically separate subpartitions. An audio application generates a first audio datastream by executing the audio subsystem. The context of a process for processing the first audio datastream is preserved in a first subpartition. The processing of the first audio datastream with the process takes place in a second subpartition. When the process commits an access violation, the process is recovered by restoring in the audio subsystem the preserved context from the first subpartition.
