Abstract: A digital TV system reduces the data rate by transmitting or recording only bytes representing half of the sampled pixels. Steering bits are also transmitted that tell which of the transmitted bytes are the closest match to the untransmitted bytes so the pixels represented by the later can be reconstructed. The steering or control bits are repeated for subsequent omitted bytes unless it no longer indicates a match within a selected tolerance or threshold.

Abstract: By analyzing the spatial-frequency spectrum of a high-resolution image into a low-pass remnant subspectrum band having a nominal high-frequency cutoff below that of one or more other spatial frequency bands, and separately transmitting each band, starting with the remnant band, over a narrow-band communication channel from a transmitter to an image display at a remote receiver, useful information as to the image contents is available more quickly to the viewer of the display than by past methods of transmitting high-resolution image information over a narrow-band communication channel for display.

Abstract: Noise reduction is achieved, without the introduction of noticeable artifacts in the displayed image, using (1) a non-ringing, non-aliasing, localized transfer, octave-band spectrum analyzer for separating the video signal representing the image into subspectra signals, (2) separate coring means for one or more of the analyzed subspectra signals, and (3) then a synthesizer employing one or more non-ringing, non-aliasing filters for deriving an output image-representing signal from all of the subspectra signals.

Abstract: A television arrangement produces a progressively-scanned display from signals representing an image scanned by a raster having lines of even fields separated vertically by a distance 2S interlaced with the lines of odd fields. For 2:1 interlace, the lines of the odd fields are spatially separated from the adjacent lines of even fields by a distance S. The lines of signal for application to the display are generated by a spatial filter having a response in the vertical direction such that an output signal occurs for each traversal of a distance S. Thus, the number of lines is doubled in each field. The lines are generated in simultaneous pairs. A parallel-to-serial converter (PISO) converts the simultaneous signals to sequential for display by progressive scanning. The PISO may be a time compressor for use with a double-rate display or a switcher for use with a vertically-dithered display. The characteristics of the filters are selected to match the psychovisual properties of the eye for eliminating line crawl, and for reducing edge flicker and motion artifacts without excessive image degradation. Advantage is taken of the psychovisual phenomenon known as adjacent band masking.

Abstract: PURPOSE: To efficiently and accurately obtain a complex signal by inserting a delay and forming information samples, simultaneously generated in each adder when signals, having time deviation in a signal group is transmitted thereby composing the composite signal in real time. CONSTITUTION: 1st input terminals of relay means 100-2 to 100-n are connected to the 1st output terminals of relay means 100-1 to (n-1) respectively. Then, sampling frequency clocks CL1 to CLn are applied to other input terminals, and other input terminals are corrected by correcting parts 345 to 349, via delays 340 to 344 and connected to adders ADD 359 to 363, respectively. For example, when a thirdly generated signal and a fourthly generated signal are combined and transmitted, it causes time deviation. Then, the 3rd signal precedented generated is delayed for a prescribed time by the delay 342 to form an information sample practically simultaneously generated in the adder 359. Thus, since the composite signal is composed only by a realtime processing, a complex signal is obtained. efficiently and accurately.
