摘要： Methods and systems for processing a sample of a media stream are provided. In one example, a method includes receiving a sample of a media stream rendered by a media rendering source, and for matching media recordings from which the sample was obtained, the method also includes receiving a signature file including a temporally mapped collection of features describing content of the matching media recordings. Each received signature file may be stored in memory. In addition, a signature stream may be received that includes features extracted from the media stream, and a number of matching features between the signature stream of the media stream and the signature file for at least one matching media recording can be determined. In one example, when substantially matching features between the signature stream of the media stream and the signature file for a matching media recording stop occurring, a discontinuity can be identified.

摘要： Methods and systems for identifying content in a data stream are provided. In one example, a client device receives a continuous data stream and substantially continuously performs a content identification of content in the data stream based on content patterns stored on the client device. The content patterns stored on the client device may include information associated with extracted features of a media file, or a temporally mapped collection of features describing a media file. The client device may determine whether the continuous data stream includes media content, and based on the determination, continuously perform the content identification of content in the data stream at the client device. The client device may query a server to determine an identity of content in the data stream based on receiving an instruction.

摘要： Systems and methods of synchronizing media are provided. A client device may be used to capture a sample of a media stream being rendered by a media rendering source. The client device sends the sample to a position identification module to determine a time offset indicating a position in the media stream corresponding to the sampling time of the sample, and optionally a timescale ratio indicating a speed at which the media stream is being rendered by the media rendering source based on a reference speed of the media stream. The client device calculates a real-time offset using a present time, a timestamp of the media sample, the time offset, and optionally the timescale ratio. The client device then renders a second media stream at a position corresponding to the real-time offset to be in synchrony to the media stream being rendered by the media rendering source.

摘要： A method and system is described which allows users to identify (pre-recorded) sounds such as music, radio broadcast, commercials, and other audio signals in almost any environment. The audio signal (or sound) must be a recording represented in a database of recordings. The service can quickly identify the signal from just a few seconds of excerption, while tolerating high noise and distortion. Once the signal is identified to the user, the user may perform transactions interactively in real-time or offline using the identification information.

摘要： A method and system for content sampling (106) and identification is presented. A data stream is recorded, and samples of the stream are identified. Samples (106) can be initially taken at random for identification. Once a sample (106) is identified and segmented within the data stream, the next time to sample (106) may be calculated to be outside the time frame of the identified sample (106). Thus, the sampling period can be adaptively adjusted to be at times after identified tracks.

摘要： A system and method are described for recognizing repeated audio material within at least one media stream without prior knowledge of the nature of the repeated material. The system and method are able to create a screening database from the media stream or streams. An unknown sample audio fragment is taken from the media stream and compared against the screening database to find if there are matching fragments within the media streams by determining if the unknown sample matches any samples in the screening database.

摘要： The invention provides a system that implements an algorithm for integrated link adaptation and power control to achieve specified error rates and to improve an overall throughput for real-time applications in wireless packet networks. The system initially divides wireless terminals into groups according to their signal path gains. Afterwards, the system can periodically adapt transmissions (i.e., link adaptations) based on the required error rates, actual error statistics and average transmission power for each wireless terminal group. Furthermore, transmission power can be adjusted by an enhanced Kalman-filter method to ensure successful reception.

摘要： A slide electronic device includes a first body, a second body, and a slide mechanism. The slide mechanism includes a first connecting member and a second connecting member. One end of the first connecting member is pivotally connected to the first body, an opposite end is pivotally connected to the second body, one end of the second connecting member is pivotally connected to the first body, and an opposite end is pivotally connected to the second body. A distance between rotary axes of the two ends of the first connecting member exceeds that of the second connecting member. When the second body slides relative to the first body, the first connecting member and the second connecting member are rotated relative to the first body and the second body until an end of the second body resists the first body and the second body is angled.

摘要： Methods and systems for performing comparisons of received data and providing a follow-on service based on the comparisons are described. In one example, a performer may utilize a portable device that includes a microphone to record a data stream of content from an ambient environment of a venue, and provide the data stream of content to a server. A user may utilize another portable device that includes a microphone to record a sample of the content from the ambient environment, and may send the sample to the server. The server may perform a comparison of characteristics of the sample with characteristics of the data stream, and can provide a response to the user with metadata. Further, based on the comparison, the server may register a presence of the user's device at the concert. The server may perform social networking functions based on results of content identification functions.
