Method and apparatus for providing graphical overlays in a multimedia system
A method and apparatus for processing overlay data in a multimedia system include processing that begins when the server of the multimedia system selects a set of channels from a plurality of channels based on a set of channel select signals. The processing continues as the server converts the set of channels into streams of channel data. The server then decodes the streams of channel data into video frames for each channel of the set of channels. The processing continues as the server generates overlay data for at least one channel based on an overlay selection input, which is provided by the client that requested the particular channel. The processing then continues as the server encodes the overlay data with video frames of at least one channel to produce channel overlay packets. The processing continues as the server encodes the video frames of the other channels into sets of channels to produce channel packets. The server then provides the overlay packets and channel packets as a stream of packets of channel data to the clients of the system. Upon receipt, each client decodes the stream of packets of channel data to isolate its channel data. The client requesting overlay data decodes the overlay packets to retrieve the overlaid video frames using the same decoding process that the other clients used to retrieve the video data of their requested channels. |

Systems and methods of searching for and determining modified blocks in a file system
The invention relates to a method of determining if a block was modified in a file system by comparing the versions of the base snapshot, the delta snapshot, and the space map block entry (b, e). In another aspect, the invention relates to a method of searching for blocks modified in a tree structured file system. The invention relates to methods and systems of snapshot management of a file system in a data storage system. To represent the snapshots, the invention maintains pointers to the root block pointer of each snapshot. When the active file system is modified, this invention avoids overwriting any blocks used by previous snapshots by allocating new blocks for the modified blocks. When the invention needs to put an established block in a new location, it must update a parent block to point to the new location. The update to the parent block may then require allocating a new block for the new parent block and so forth. Parts of the file system not modified since a snapshot remain in place. The amount of space required to represent snapshots scales with the fraction of the file system that users modify. To maintain snapshot integrity, this invention keeps track of the first and last snapshots that use each block in space map blocks spread throughout the file system data space. When users delete snapshots, this invention may use a background process to find blocks no longer used by any snapshot and makes them available for future use. |

Adaptive place-pitch ranking within a multi-channel neural stimulator
An adaptive place-pitch ranking procedure for use with a cochlear implant or other neural stimulation system provides a systematic method for quantifying the magnitude and direction of errors along the place-pitch continuum. The method may be conducted and completed in a relatively short period of time. In use, the implant user or listener is asked to rank the percepts obtained after a sequential presentation of monopolar stimulation pulses are applied to a selected spatially-defined electrode pair. The spatially-defined electrode pair may be a physical electrode pair or a virtual electrode pair. A virtual electrode pair includes at least one virtual electrode contact. Should the patient's judgment of pitch order be correct for all applied interrogations, then no further testing involving the tested electrode pair (two electrode contacts) is undertaken. However, should there be errors in the place-pitch ranking, which errors evidence perceptual place-confusions, then a search is undertaken for the spread of the perceptual confusion. This search for the spread of confusion continues until no errors are made in all directions. Identified channels wherein pitch confusion exists may be de-selected (not used) during normal operation of the cochlear implant or other neural stimulation system. |

Method and system for using user equipment to compose an ad-hoc mosaic
An application that runs on a User Equipment (UE) in one of three main modes: (1) listener, (2) proxy, or (3) controller, and defaults to listener mode. A UE is placed by a user into controller mode, which causes the application to scan the area covered by its Bluetooth radio and identify other Bluetooth enabled devices. For all the Bluetooth devices found, the controller attempts to contact the UEs in listener mode to form a group of interested listeners. The UE in controller mode then sends a message to all group members. The message alerts the user of each UE in listening mode to prepare to take a photograph or video. The UE in listener mode provides the users with audio and visual cues and after a time period each UE in the group takes a photograph or a video. |

Multicarrier modulation systems
The invention provides a new approach which is better suited to FFT design as applied to multicarrier modulation systems such as OFDM. The signals are scaled so that overflow, rather than being completely avoided, occurs with low probability throughout the IFFT and FFT structures. The size of the error that results from an overflow depends on how overflow is handled in the DSP. To minimize the degradation, overflow should result in saturation of the value at the maximum positive or negative value option. This is equivalent to clipping the signal. Using the new technique, signals within the FFT structure are scaled to balance the effect of clipping and round-off. Clipping may result in comparatively large errors in a few signal values but because of the spreading effect of the FFT and because OFDM systems typically include error coding/correction, system performance depends on the total error or, in other words the total noise power, across all of the FFT outputs rather than on any individual value. |

Measuring noise power at wireless receivers using pilot symbol information
Embodiments are directed to a wireless receiver system that utilizes a special structure of pilot symbols used for synchronization and channel estimation in transmission packets to measure noise power at the receiver. The periodicity of the pilot signal sequences is used to extract the noise power from the received signal. Such extraction is achieved by subtracting the received signals from two pilot slots which are separated by the known periodicity of the training sequence. This method relies on the fact that desired signal and system interference signals will cancel out after the subtraction process. Measuring the power of the residual signal after subtraction represents the estimate of the noise power. Several consecutive such residual signals can be first summed up before measuring the power to improve the estimate of the noise power at the receiver. To further improve the performance, estimates of the desired signal produced by a channel estimation block can be first subtracted from each of the received signals on two pilot slots which are then to be subtracted and are separated by the known periodicity of the pilot sequence. |

Since the halftoning is done in the hardware just before printing, the print direction relative to the threshold matrix is known. No rotation capability is needed in the hardware. If an image needs to be rotated, it can be done previously to being sent to the hardware. Furthermore, because a pair of pels are turned on for the lightest values (or possibly with a one level difference between the first and second dots in the pair), the electronics are stressed less. Moreover, the drive will be at a lower frequency than the first dot in the traditional halftone cell, which remains isolated for many levels. |

Method and apparatus for background replacement in still photographs
A first digital image is acquired of a framed area while illuminating the background and foreground object under a first lighting condition. A second digital image is then acquired of the same framed area while illuminating the background and foreground object under a second lighting condition. Preferably, the first lighting condition illuminates the background without illuminating the foreground object so that a silhouette of the foreground object is acquired in the first image. The second lighting condition illuminates the foreground object (e.g., with frontal lights). Due to the difference in the illumination between the background and silhouette in the first image, an alpha mask can be created from the first acquired image. Using the mask, the background from the second image can be removed and replaced by virtually any other desired background image. |
