    A high speed focus control method is one of the important features of a video camera. This paper presents a new optical detector (OPD) that provides a high-speed auto focus (AF) control. The optical detector detects data to control AF, auto exposure (AE) and auto white balance (AWB). A conventional optical detector detects only one characteristic data in a field, however, the new OPD detects sever... View full abstract»

    A determinate global data transfer timing scheme will significantly reduce the complexity of global control and ease constraints on sub-modules. Such a scheme allows to construct functional modules based on an explicit performance and data flow requirement. A very low gate count hardware architecture for MPEG decoder is presented to demonstrate the concept View full abstract»

    The performance of two different channel interpolation methods to be used with orthogonal frequency division multiplexing systems are investigated. The considered schemes use constant pilot frequencies for channel response estimation. The interpolation techniques are piecewise-constant and piecewise-linear methods which due to their inherent simplicity are straightforward to implement. The results... View full abstract»

    A television ghost is measured by synthesizing the ghost waveform demodulated by an in-phase synchronous demodulator. For this purpose, the calculated in-phase and quadrature demodulated waveforms of known transmitted waveforms are prepared at the receiving site. A ghost path is constructed by a software simulator where a ghost waveform is synthesized by changes in the ghost parameters consisting ... View full abstract»

    Publication Year: 1996, Page(s):998 - 1002
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (556 KB)

    In magnetic tape recording, two approaches have emerged in which essentially the same medium is tracked in two different ways: rotary- and stationary-head recorders. Both approaches are commonly employed in digital audio and data recording, but since the introduction of the first analog video recorders in the early 50s, rotary-head recorders (either helical or transverse scan) have held undivided ...

  • A study on technology for optimization of tape loading

    Publication Year: 1996, Page(s):952 - 958
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (784 KB)

    The tape thickness and width are reduced in order to realize high-density recording, long time recording and small mechanism (e.g., digital-VCR). Thus, the tape stiffness becomes very low and the tape tends to be damaged. We have developed a new methodology and a new analysis system to optimize the tape damage free loading mechanism design View full abstract»
