Abstract: Certain embodiments described herein provide methods and systems for media recognition. One exemplary embodiment involves recognizing a piece of media in two steps. First, a watermark may be recognized that identifies that the media has a media identifying fingerprint. Second, that fingerprint is retrieved and used to recognize the media content. Using a combination of watermarking and fingerprinting techniques provides various advantages, for example, it may address traditional inaccuracies involved with watermarking while reducing the computational power and bandwidth required to analyze every piece of media for a fingerprint.

Abstract: Content matching using phoneme comparison and scoring is described, including extracting phonemes from a file, comparing the phonemes to other phonemes, associating a first score with the phonemes based on a probability of the other phonemes matching the phonemes, and providing the file with another file when a request is received to access one or more files having a second score that is substantially similar to the first score.

Abstract: Audio comparison using phoneme matching is described, including evaluating audio data associated with a file, identifying a sequence of phonemes in the audio data, associating the file with a product category based on a match indicating the sequence of phonemes is substantially similar to another sequence of phonemes, the file being stored, and accessing the file when a request associated with the product category is detected.

Abstract: Some embodiments provide methods for use in storing digital content on a storage media. These methods store a first portion of digital content on a first portion of a storage media; store a second portion of digital content on a second portion of the storage media separate from the first portion of digital content, wherein the second portion of digital content is read separately from the first portion of digital content on the storage media and does not affect the reading of the first portion of digital content; and store control information on the storage media, wherein the control information defines a combination of the first portion of digital content and the second portion of digital content for reproduction of a unified digital content.

Abstract: Some embodiments provides a highly directional audio response that is flat over five octaves or more by the use of multiple colinear arrays followed by signal processing. Each of the colinear arrays has a common center, but a different spacing so that it can be used for a different frequency range. The response of the microphones for each spacing are combined and filtered so that when the filtered responses are added, the combined response is flat over the selected frequency range. To improve the response, the output of the microphones for a given array spacing can also be filtered with windowing functions. To receive the response from other directions a “steering” delay may also be introduced in the microphone signals before they are combined. Some embodiments can also extend to two and three dimensional arrays.

Abstract: A repeater (40) for Small Computer System Interface (“SCSI”) buses (52, 54, 56, and 58) to which digital computing devices (62, 64, 66, 68, 72 and 74) connect in parallel. The repeater (40) includes a plurality of bus interface circuits (48) that are connected to the SCSI buses (52, 54, 56 and 58) for receiving signals from and transmitting signals to devices (62, 64, 66, 68, 72 and 74) connected thereto. The bus interface circuits (48) connect to a control circuit (44), that responds to various phases of the SCSI bus protocol: 1. which stores information for use during a subsequent phase of the SCSI bus protocol; and 2. thereby allows signals to be exchanged between pairs of the SCSI buses (52, 54, 56 and 58) during a succession of bus phases occurring on the buses (52, 54, 56 or 58).

Abstract: Techniques of making a recording of or transmitting a sound field from either multiple monaural or directional sound signals that reproduce through multiple discrete loud speakers a sound field with spatial harmonics that substantially exactly match those of the original sound field. Monaural sound sources are positioned during mastering to use contributions of all speaker channels in order to preserve the spatial harmonics. If a particular arrangement of speakers is different than what is assumed during mastering, the speaker signals are rematrixed at the home, theater or other sound reproduction location so that the spatial harmonics of the sound field reproduced by the different speaker arrangement match those of the original sound field. An alternative includes recording or transmitting directional microphone signals, or their spatial harmonic components, and then matrixing these signals at the sound reproduction location in a manner that takes into account the specific speaker arrangement.
