1476 results about "Time shifting" patented technology

In broadcasting, time shifting is the recording of programming to a storage medium to be viewed or listened to after the live broadcasting. Typically, this refers to TV programming but can also refer to radio shows via podcasts.

Low power pulse oximeter

A pulse oximeter adaptively samples an input signal from a sensor in order to reduce power consumption in the absence of overriding conditions. Various sampling mechanisms may be used individually or in combination, including reducing the duty cycle of a drive current to a sensor emitter, intermittently powering-down a front-end interface to a sensor detector, or increasing the time shift between processed data blocks. Both internal parameters and output parameters may be monitored to trigger or override a reduced power consumption state. In this manner, a pulse oximeter can lower power consumption without sacrificing performance during, for example, high noise conditions or oxygen desaturations.

Code synchronization in CDMA satellite wireless communications system using uplink channel detection

An uplink signal transmitted by a terminal is received by a satellite wireless communications system. The uplink signal includes a known information element, e.g., a reverse access channel (R-ACH) preamble, spread according to a spreading code specific to a component of a satellite wireless communications system, e.g., a pseudonoise (PN) sequence associated with a satellite beam. A correlation of the received uplink signal with the spreading code over a range of time shifts is determined. The known information element is detected from the determined correlation. The satellite wireless communications system is synchronized with the terminal responsive to detection of the known information element. For example, a delay may be assigned to a receiver of the satellite wireless communications system responsive to detection of the known information element.

Method and Apparatus for Delivering Consumer Entertainment Services Accessed Over an Ip Network

The present invention provides IP-centric, multi-channel, time-shifted and real-time telecommunications services to a plurality of system users. The system can capture both digital and analog multi-channel feeds and, through a cross-connect layer, can convert the signals to a digital format and subsequently send them to an encoder to be compressed. The encoding process can use a firmware upgradeable software developed to decrease data bitrates while retaining quality of the information at a desired level. The encoded, compressed signals may either be stored on a data-on-demand server for later viewing services, such as television / video-on-demand or audio-on-demand, or may be streamed directly to system users using a Media Streaming Subsystem (MSS). The MSS can be responsive to a system user request and operative to forward a selected stream of compressed digital data to the system user via a gateway means. The system can include a System Controller that can provide management and control of the system components and services provided by the system. The gateway means is able to receive compressed digital data from the Media Streaming Subsystem and transmit that data to a system user sending a request over a communication network. A cable modem, DSL modem or other appropriate interface can be located at each system user's location, thereby providing a means for sending multiple signal sources to a system user's Local Area Network (LAN) to which the User Computing Device(s) (UCD) of a system user are connected. The UCD receives the compressed data from the gateway means, subsequently decodes this compressed data and presents this decompressed information to the system user via a presentation system which may or may not be integrated into the UCD, thereby providing the requested entertainment services to the system user.

Signal modulation method resistant to echo reflections and frequency offsets

A method of modulating communications signals, such as optical fiber, wired electronic, or wireless signals in a manner that facilitates automatic correction for the signal distortion effects of echoes and frequency shifts, while still allowing high rates of data transmission. Data symbols intended for transmission are distributed into N×N matrices, and used to weigh or modulate a family of cyclically time shifted and cyclically frequency shifted waveforms. Although these waveforms may then be distorted during transmission, their basic cyclic time and frequency repeating structure facilitates use of improved receivers with deconvolution devices that can utilize the repeating patterns to correct for these distortions. The various waveforms may be sent in N time blocks at various time spacing and frequency spacing combinations in a manner that can allow interleaving of blocks from different transmitters. Applications to channel sounding / characterization, system optimization, and also radar are also discussed.

Comparing audio using characterizations based on auditory events

A method for determining if one audio signal is derived from another audio signal or if two audio signals are derived from the same audio signal compares reduced-information characterizations of said audio signals, wherein said characterizations are based on auditory scene analysis. The comparison removes from the characterisations or minimizes in the characterisations the effect of temporal shift or delay on the audio signals (5-1), calculates a measure of similarity (5-2), and compares the measure of similarity against a threshold. In one alternative, the effect of temporal shift or delay is removed or minimized by cross-correlating the two characterizations. In another alternative, the effect of temporal shift or delay is removed or minimized by transforming the characterizations into a domain that is independent of temporal delay effects, such as the frequency domain. In both cases, a measure of similarity is calculated by calculating a coefficient of correlation.

Method for wedge time shift calibration in a disk drive

A method is disclosed for identifying wedge time shift zones on a magnetic disk of a disk drive. The disk drive further includes a spindle motor for rotating the disk at an operating speed in response to a spindle control current generated by a spindle control system, and a head that is actuated over the disk. During operation, the control systems causes a seek of the head across the disk and measures wedge-to-wedge times between servo wedges. The control system then calculates a wedge-to-wedge time shift value using the wedge-to-wedge times and determines whether the wedge-to-wedge time shift time value exceeds a predetermined threshold. If the wedge-to-wedge time shift value exceeds the predetermined threshold, then the control system identifies a wedge time shift zone, and stores information for compensating for the identified wedge time shift zone during disk operations.

Adaptive timing recovery via generalized RAKE reception

A method and apparatus for determining operating modes in a receiver is described herein. A delay searcher in the receiver detects a signal image in the received signal. When the receiver is a RAKE receiver, a plurality of RAKE fingers coherently combine time-shifted versions of the received signal at different delays. Alternatively, when the receiver is a chip equalization receiver, an FIR filter coherently pre-combines the signal images in the received signal. A processor determines delays. In particular, the processor generates a first signal quality metric for a single-delay receiver mode, and generates a second signal quality metric for a multi-delay receiver mode. Based on a comparison of the first and second signal quality metrics, the processor selects the single-delay or the multi-delay receiver mode for processing the signal image.

Device and method for bandwidth optimization using a local cache

A device 60 for time-shifting a first signal set with respect to a second signal set, as compared to the time sequence in which they were received, includes a receiver 44B, 46B, a storage means 44C, 46C, 70, a central processing unit 66, and a user interface 72. The first signal set 38 bears a cache marker 34 that directs the CPU to store it in a local storage. The second signal set 40 bears a recall marker 36 that uniquely identifies the first signal set 38 through the cache marker 34, and that determines a sequence in which the first and second signal sets are to be output. The CPU uses the recall marker and cache marker to sequence the first and second signal sets relative to one another in time that differs from the timed relation in which they were received. By storing the first signal set in a local storage, it need be broadcast or transmitted only once, eliminating the need to re-broadcast recurring commercial advertisements and conserving bandwidth.
