    摘要： A pixel preheat system for a thermal transfer device in which a selected image is transferred from a strip of color carrying ribbon to a strip of image carrying tape achieves precise control of the temperature of the individual pixel heating elements in a thermal printhead by combining the pixel data values just printed with the pixel data values to be printed to generate a pixel preheat value whenever either of the pixel data values is off or white. The present invention maintains the temperature of the individual pixel heating elements closer to the transition temperature of the thermal transfer ribbon and uses fewer circuit components.

    摘要： An architecture for a memory with a wide word, e.g. n-byte, width particularly suited for use as a high definition video frame store memory (80), and an accompanying organization for storing pixel data therein to facilitate efficient block and raster access therefrom. Specifically, the memory relies on storing n-byte wide words (n=(m.sub.1 .times.m.sub.2)) across m.sub.2 independent m.sub.1 -byte wide memory segments, with pre-defined positional offsets between respective m.sub.1 -byte words (203)("nibbles") stored in successive memory segments. All these segments are simultaneously accessed on a read or write basis. During a memory write operation, all the nibbles in an n-byte wide input word are appropriately shuffled to yield the proper inter-segment offsets prior to being written into the memory as a collective n-byte memory write word. During a read operation, all the nibbles read from memory in a collective n-byte memory read word are appropriately shuffled to yield an n-byte output word. Inasmuch as either a scan line or sub-block (210.sub.W, 210.sub.X, 210.sub.Y, 210.sub.Z) of a macroblock of pixel data is collectively written to or read from the memory during one memory write or read operation, with shuffling occurring on a pipelined basis therewith, each of these two widely differing forms of memory access can each occur at a very high efficiency and hence at essentially full memory bandwidth. This permits that memory to be fabricated from relatively inexpensive memory circuits.

    摘要： A control system for a thermal transfer device in which a selected image is transferred from a strip of color carrying ribbon to a strip of image carrying tape and precise alignment between adjacent columns of vertical print is achieved by monitoring and controlling the rotational speed of the drive means for the thermal transfer device and activating the printing of each column of pixel data based upon positional information of the tape and ribbon determined in relation to the rotational speed of the drive means so that each column of pixel data is of a uniform and consistent width.

    摘要： Video disc track numbers are conveyed during each video line by means of data subcarriers present in the recorded stereo audio channels. Upon playback, the data sequence is processed to identify tracking errors occurring within each video field to thereby enable immediate correction of disc tracking errors on a line-by-line basis thus minimizing picture and sound interruption caused by intra-field tracking errors.
