Abstract: A compound word spelling verification technique is described for use with a dictionary which does not include all verifiable compounds. During attempted verfication of a text word, all initial substrings of the word found in the dictionary are saved in a list. If the entire word is not found in the dictionary, the longest substring in the substring list is subtracted from the entire word to be verified to yield a "remainder" portion of the input text word. The dictionary words are then compared with this remainder portion to determine if a match occurs. If so, then both portions of the word are found in the dictionary and spelling of the word is considered correct. If the remainder is not found in the dictionary, successively shorter initial substrings are accessed to yield successively longer remainders. The word is considered correctly spelled if both a substring and a remainder are found in the dictionary. This techinque is applied recursively so that multiple-piece compounds can also be found.

Abstract: In editing video still pictures, the pictures are reproduced from a video disk and displayed one by one in combination with subject-matter categories into which they may be grouped. The list of categories appears as a descriptive overlay on each picture being evaluated. Ordinarily, some pictures are assigned to categories and some are skipped. It often happens that it is necessary to reevaluate the pictures that were skipped during the initial stage of evaluation. To encourage such a reevaluation, a special editing feature is provided for retrieving and redisplaying only those pictures that were not initially assigned to a category. Since these pictures are not intermixed with those already assigned to categories, they are quickly retrieved and conveniently assigned, if desired, to one or more of the subject-matter categories.

Abstract: A dictation and editing system includes microphone and keyboard inputs to a programmed computer system. The author may control the selection and entry of microphone and keyboard inputs for storage and display. Keyboard entries are displayed as alpha-numeric or other characters, while recorded speech is displayed simply as a sequence of box-like characters called voice token marks. Each token mark indicates 1 second of speech, and one line of marks represents 60 seconds of speech.

Abstract: A video editing viewer for use in editing a television signal is disclosed. A plurality of frames of the input television signal stored in a memory are repeatedly read-out and a frame picture array is displayed on a screen of a monitor. The frame picture array is moved forwardly or backwardly at any desired speed. Thus a user can see the frame picture array as if he was looking at a cinefilm. A marker is also displayed on the monitor and can be moved along the picture frame array. When a cue button provided on a panel is pushed, a time code of a frame indicated by the marker can be registered as an editing point. Therefore, the editing operation can be effected in an easy and accurate manner.

Abstract: Disclosed is an improved system for verifying the spelling and providing hyphenation points for text words from a plurality of interspersed languages. The control system includes control codes which are inserted in the text to define the language of the text following the control code. The system accepts the control codes and responds by comparing the text following the control code against a storage dictionary of correctly spelled words and hyphenation points for the language associated with the control code. The system provides as an output an indicator of whether the word is correctly spelled or where the proper hyphenation points for the word appears. The systemn further includes control codes which when detected will cause blocks of data which should not be compared to the storage dictionary to be skipped.

Abstract: A separately packaged film sound editor mixer is disclosed which includes a plurality of low level audio signal input terminals adapted for connection to outputs from playback heads of a synchronizer. Magnetic tape preamplifiers are included for preamplification of the low level signals. The preamplified signals are connected through slide attenuators and muting switches to inputs of a first summing amplifier. The output from the first summing amplifier is connected to inputs of left and right channel summing amplifiers through a tone control circuit and a master attenuator of the slide type. A selector switch is included in the input for one of said magnetic tape preamplifiers whereby, in one switch position, an output from the synchronizer is supplied to the preamplifier, as mentioned above.

Abstract: A digital editing system includes first and second memories in which audio data and weighting factor data are respectively stored. The audio data are sequentially retrieved from the first memory and multiplied by corresponding weighting factor data retrieved from the second memory. A coincidence detector detects when predetermined storage locations of the memories are addressed. The weighting factor data has a unity or zero value during the time prior to the occurrence of an output from the detector, whereupon it changes its value as a function of time until it reaches to zero or unity and remains at the final value thereafter. The direction of variation of the weighting factor data can be appropriately selected to modify the audio data into a so-called "fade out" of "fade-in" pattern at a desired point of the audio program. A pair of such editing systems is required for editing audio programs from different sources for storing such programs in a pair of first memories.

Abstract: A voice message from a user telephone (11) is recorded (FIG. 3) by being converted to digitally coded form and processed through a computer memory (32) prior to placement in bulk storage (31) memory sectors of uniform size. The message is retrieved in a playback operation (FIG. 4). Signal energy estimates for respective memory-sector-sized parts of the message are computed, stored, and used for various purposes including message playback speed control. User-originated command data messages to the computer cause editing of the message in accordance with the commands. To effect editing, the user directs the establishment of one or more pointers at selectable silent-sector points in the message, orders the computer to display the pointer relative positions, and orders a selectable editing operation with reference to at least one of the displayed pointers.

Abstract: A time code correction circuit is formed of an input circuit for receiving an input time code; first and second memories for storing data representing the time code; an adder for selectively incrementing or decrementing data to be supplied to the first and second memories; a comparator comparing the data stored in the first memory with the input time code; a switch controlled by the comparator for selectively supplying the adder with the input time code and the data started second memory; and an output circuit coupled to provide the contents of the second memory as a corrected output time code. Where the time code is reproduced from a time code track recorded on a magnetic tape, the correction circuit is favorably adapted to produce a continuous time code sequence despite dropout in the recorded time code. Also, if a jump occurs in the recorded time code sequence, the correction circuit causes the output time code to reflect such jump with a minimum of signal disturbance.

Abstract: An electronic timepiece having an A.M. and P.M. display function. The characters A or P are displayed during time setting or correction by one discretionary display element of a plurality of display elements normally used for displaying time.
