摘要： Disclosed are a system, a method, and an article of manufacture to provide for the detection and compensation of tape breakage in a tape drive. The invention operates by simultaneously monitoring the tape reel rotation direction and the ratio of rotation between the tape reels. If the rotation direction is not the same for both reels, then tape breakage is indicated and reel rotation ceases. Tape breakage is also detected if the tape reel angular rotation ratio between the supply and take up reels is not within a specified tape reel ratio range. The tape reel angular rotation ratio is detected by simultaneously measuring the angular rotation of each tape reel in a specified time period and then calculating the ratio. The present invention detects the tape reel angular rotation ratio and if tape reel angular rotation ratio is outside of the specified tape reel ratio range, tape breakage is indicated and reel rotation ceases.

摘要： In a tape having separate servo bands of patterns positioned laterally across the tape, the patterns of a separate servo band have at least one differentiating characteristic with respect to patterns of another of the separate servo bands. The differentiating characteristic allows identification of the separate servo bands. For example, the patterns of a separate servo band have differing azimuthal orientations of detectable transitions with respect to another servo band, such as being laterally inverted. In another, variations in the width of gaps of patterns are made with respect to another servo band. In another, variations are made in the number of the detectable transitions of patterns with respect to the patterns of another servo band.

摘要： In magnetic tape having separate longitudinal servo bands of servo information with superimposed data information, the separate servo bands have selected different superimposed data information, to identify the separate servo bands for independent addressability. The servo information comprises non-parallel laterally extending transitions to indicate lateral positioning, and the selected different superimposed data information may comprise a lack thereof in portion(s) of the servo bands. Where the superimposed data information is longitudinal position information of the tape, the selected different superimposed data information may comprise different longitudinal position information of one or more servo band(s). The selected different superimposed data information may comprise a band identifier in the superimposed data information of one or more of the servo bands.

摘要： A motion vector detecting circuit calculates a residual between the reference block read from a frame memory and retrieving block at the predetermined position of a retrieving frame to output to an operation control circuit. The operation control circuit discriminates whether a residual value supplied from the motion vector detecting circuit is larger than the threshold value Th1 and the threshold value Th2 which is smaller than Th1 or not respectively and controls the vector detecting circuit corresponding to such discrimination result. When the residual value is larger than the threshold value Th1, the motion vector detecting circuit instructs execution of the motion vector detecting process utilizing the comparatively wider retrieving range. When the residual value is less then the threshold value Th1 and is larger than the threshold value Th2, the motion vector circuit instructs execution of the motion vector detecting process utilizing the comparatively narrower retrieving range. Moreover, when the residual value E is less than the threshold value Th2, the motion vector detecting circuit instructs stop of execution of the motion vector detecting process. As explained above, the motion vector detecting process can be executed corresponding to the input image data.

摘要： The invention relates to a device and method for image coding. A reference frame memory for storing image data of a reference frame, a search memory for storing image data of a search frame, a motion detection means for reading image data from the reference frame memory and the search memory and calculating it to detect a motion vector, and a judgement means for generating a motion vector distribution from the motion vector detected by the motion detection means on a search range of the search frame M fields or M frame (M is an integer of one or larger) apart from the reference frame and deciding a search position between images N fields or N frames (N is an integer larger than M) part based on the motion vector distribution are provided, and the motion detection means performs motion detection at the search position decided by the judgement means. The search range can be thereby enlarged without increment of the search block transfer rate when an image is coded.

摘要： A reference frame block from a memory is supplied to a feature extraction circuit and a search frame block from a separate memory is supplied to a feature extraction circuit. Within the extraction circuits, the frame blocks are divided into minor blocks and the integration of all pixels for each minor block gives a matching element. A matching process with the matching elements from the extraction circuits provides a frame motion vector. Data division circuits divide the matching elements provided from the extraction circuits into odd- and even-field matching elements, and the matching process with the odd- and even-field matching elements provides odd- and even-field motion vectors. This eliminates the need for a feature extraction circuit when obtaining field matching elements.

摘要： An apparatus and method for encoding picture data. A motion vector is detected and a distribution range of the detected motion vector is determined. Based upon such distribution range, a motion vector search range is predicted and set. Detection for the next motion vector is performed within the set search range. The picture data and/or motion vectors are variable length encoded, wherein codes having relatively short lengths may be utilized. As a result, the amount of information generated during such encoding may be relatively small. Upon reproduction of such encoded data, a picture having relatively high quality may be produced.
