摘要： The present invention involves an apparatus and method for processing of digital information that includes duplication of information from each channel of a multi-channel recorder on main and backup tracks and provides a combination of error detection apparatus and procedures where data groupings or words on each track are individually subject to four separate tests for detecting errors and provides, from that analysis, for a selection of most likely correct data for further processing. Additionally, further system reliability is obtained by providing circuitry whereby a detected error activates a selection of data groupings coming before and after the detected error, providing where appropriate, for switching from main to backup track data over a certain number of data groupings. The present invention further provides a unique synchronization coding format with circuitry and a procedure for its use for rapidly acquiring synchronization coding in a data flow and includes an arrangement for averaging the content of first-in-first-out buffers of each track for controlling tape speed to enable a smooth over-dubbing of information recorded at different times on separate tracks.

摘要： A method of developing a set of colorant signals representing substantially exact amounts of colorants required to reproduce a color in a medium includes the steps of using a scanner to develop a first set of scanner signals, processing the set of scanner signals in an iterative conversion loop and selecting a set of colorant estimates developed by the iterative conversion loop that meets a solution criterion as the set of colorant signals. The colorant signals may thereafter be converted to colorimetric data by a converter.

摘要： The synchronization circuitry can be described as operating in essentially four states and is particularly useful at startup, to locate synchronization codes and spacing there between in the data flows. In operation, the synchronization circuitry looks in a data flow at startup for any sync code and, when such sync code is found, counts ahead to where the next sync code should be. If a proper sync code is found, again the circuitry counts ahead to where the next sync code should be, continuing looking at points along the data flow until a certain number (n) of properly located sync codes are discovered whereat synchronization is declared and normal playback is ordered. However, if sync codes are not located where they should be in the data flow, then such failures are subtracted from success until either (n) successes are found or a total of successes less failures reaches zero whereat the circuitry returns to the first state of looking for any sync code.

摘要： The present invention involves apparatus and techniques for converting analog data, preferably audio signals, to digital information, which digital information is preferably recorded from two separate main channels onto main tracks and includes a third or backup track for recording thereon partial or most significant portions of that information recorded on the main tracks. The invention involves apparatus and techniques of each data group on each main track and the backup track; checking for synchronization codes arranged between data groups; and checking for a match of that appropriate portion of the main track data against the data on the backup track, with, when potentially erroneous or questionable data is detected, the invention providing for comparison of main and backup track data groupings for determining which is most likely correct or, in the case where neither data grouping is identifiable as most likely correct, the invention provides for substitution of last correct data or integration between good data. The preferred invention incorporates clocking at the signal input for data stablization, and first-in-first-out circuitry at the output for reducing the effects of wow and flutter to produce a very high quality conversion of digital to analog form to pass to a speaker system.
