International Classification:

H04K 1/10

US Classification:

375260, 370209

Abstract:

Disclosed are methods and apparatus for synchronizing tile processing and assignment processing in a communication device. In particular, the methods and apparatus utilize a tile processing scorecard with a number of assertable bits corresponding to a number of tiles to be tile processed. As each tile is tile processed, the scorecard or bit indicators are asserted to indicate that the tile has been processed. Assignment jobs, which involve codewords having information from symbols in multiple tiles are processed after all of the pertinent tiles are tile processed. The scorecard information is accessible for assignment processing to determine which tiles have been processed, thus affording synchronization of tile processing with assignment processing, while maximizing the independence of these two processing operations. Tile processing operations may further use the scorecard information to prioritize or order tile processing in relation to known queued assignment jobs.

US Classification:

600443

Abstract:

A digital video recorder is provided which provides digital storage of realtime ultrasonic image sequences, replacing the conventional VCR with a recorder which does not degrade digital ultrasound images by analog conversion and recording. The capacity of the digital video recorder is extended by the ability of the digital video recorder to compress ultrasound image data prior to storage and the ability to decompress compressed image data retrieved from storage for realtime display.
