    摘要: Apparatus for directly recording television signals on a magnetic medium strips out sync and blanking information. Low frequency components of the television signals are time-compressed, i.e., frequency shifted, and recorded as a substitute for the stripped-out sync and blanking information. Thus, high frequency components of each video line are recorded, followed by that line's low frequency components, thereby facilitating the playback of low frequency information. In a preferred form, the low frequency video information is time-compressed sufficiently to provide time, during the time slot which corresponds to sync and blanking information, for the recording of reference signal information. During playback, the reference signal information is employed to set the gain of the playback circuit.

Thus, high frequency components of each video line are recorded, followed by that line's low frequency components, thereby facilitating the playback of low frequency information. The low frequency video information is time compressed sufficiently to provide time, during the time slot which corresponds to sync and blanking information, for the recording of reference signal information. During playback, the reference signal information is employed to set the gain of the playback circuit. In time compressing the low frequency information, the video signal content of a line is sampled at a predetermined rate. Each sample is then quantized for purposes of improving playback signal-to-noise ratio, i.e. the effect of tape modulation, and other, noise is nullified by sample quantization. To assure against the loss during playback of significant low frequency signal information, the quantization bits are rearranged according to their significance, bits of higher significance being recorded in proximity to the reference signal information, and vice versa.

    摘要: A method, computer-usable medium, and system for processing graphical data for display on a multi-component display is disclosed. Embodiments improve the display quality of multi-component displays by modifying graphical data to preemptively compensate for distortion caused by interstitial layers and/or display screens of the multi-component display, thereby enabling display of graphical objects from multi-component displays with improved optical characteristics. For example, where components of a multi-component display blur displayed images, graphical data used to display graphical objects may be modified to sharpen the graphical objects before display. The pre-sharpening amplifies the high frequency components of the displayed graphical objects to compensate for the dampening caused by passing the graphical objects through the components of the multi-component display.
