Abstract: A content alignment service is described that may generate content synchronization information to facilitate the synchronous presentation of corresponding audio content and textual content. In some embodiments, portions of body text (as opposed to front matter, such as a table of contents; or back matter, such as an index) in the textual content are identified and synchronized with corresponding audio content. In one example application, an audiobook may be synchronized with an electronic book. As the body text portions of the electronic book are consumed, corresponding words of the audiobook may be audibly presented.

Abstract: A content alignment service may generate content synchronization information to facilitate the synchronous presentation of audio content and textual content. In some embodiments, a region of the textual content whose correspondence to the audio content is uncertain may be analyzed to determine whether the region of textual content corresponds to one or more words that are audibly presented in the audio content, or whether the region of textual content is a mismatch with respect to the audio content. In some embodiments, words in the textual content that correspond to words in the audio content are synchronously presented, while mismatched words in the textual content may be skipped to maintain synchronous presentation. Accordingly, in one example application, an audiobook is synchronized with an electronic book, so that as the electronic book is displayed, corresponding words of the audiobook are audibly presented.

Abstract: Digital items of dynamic content may be navigated by content elements associated with the item of dynamic content. In some embodiments, a voice command or natural language query is obtained from a user to whom the item of dynamic content is being presented. The voice command or natural language query may be processed to identify a content element to which the user wishes to navigate. The item of dynamic content may then be presented starting at a presentation position at or near a presentation position with which the content element is associated.

Abstract: The invention comprises a system and method for correcting jitter and frame erasure in packet voice communication systems with out severely affecting the voice quality of the signal to be easily noticed by a listener. A packet is retrieved from a buffer, a pitch of the packet is determined, and the pitch of the packet is processed in a manner determinative of whether a next packet has arrived.

Abstract: A telephone apparatus enables the approximate simultaneous transmission and reception of audio interleaved with image and graphical annotation signals, in data packet form, over an analog line which connects the apparatus to a switched telephone network. The audio data packets are transmitted at a periodic rate, during a first time interval, and the image and annotation data packets are transmitted during a second time interval, following the first time interval, enabling the simultaneous output of voice, image and annotation data at the receiver site. Control data packets, as needed, are also transmitted during the second time interval for end-to-end apparatus control. One feature enables the transmission of audio data packets at a first periodic rate, when in an image transmission mode, and at a second periodic rate, faster than the first periodic rate, when not in the image transmission mode.

Abstract: An imaging system apparatus and operating method thereof utilize a volumetric resampling technique with interpolation to determine sample point values on user-defined paths traced through a volumetric image comprising a group of predefined data values, which are themselves samples of a continuous volumetric object. Data values to be displayed are determined from the sample point values using user-selected interpolation and visualization operating modes.

Abstract: A facility is provided for greatly enhancing the rate at which volumetric data is processed by display on a two-dimensional display. Specifically, the volumetric data is first divided into a predetermined number of sub-blocks, in which a predetermined voxel in each sub-block is then transformed into an associated picture element. The sub-blocks and their associated pixels are then supplied to respective processors forming an array of processors. Each processor then completes the transformation of its sub-block as a function of the coordinates of the associated picture element and respective incremental vectors.
