摘要： Pipe-line architecture is employed for analyzing in delayed real time the frequency spectrum of an information component (having one or more dimensions) of a given temporal signal having a highest frequency of interest of no greater than f.sub.0, and/or for synthesizing in delayed real time such a temporal signal from the analyzed frequency spectrum thereof. Such pipe-line architecture is particularly suitable for image-processing the two-dimensional spatial frequencies of television images defined by a temporal video signal.

摘要： The image represented by a video signal contains an associated image spectrum defined within a spatial-temporal frequency volume. From this video signal, a second video signal is produced that represents spatial-temporal carrier modulation of a spectral section of the image spectrum into an interleaved location adjacent the image spectrum. To reduce the visibility of aliasing artifacts, the interleaved spectral section is made to be of reduced amplitude relative to its original amplitude in the image spectrum. To reconstruct the spatial-temporal frequency spectrum of the image at the television receiver, the video signal containing the frequency interleaved spectrum is processed in a complementary manner that represents spatial-temporal carrier modulation of the interleaved section to restore that section to its original position in the image spectrum. At the same time, the amplitude of the restored section is increased.

摘要： 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.

摘要： In a television receiver, a demultiplexer for a high definition multiplexed analog component television signal provides samples of each component signal. A group of samples for each component signal is selected according to the aspect ratio of the television receiver display, and according to the aspect ratio of the picture contained in the high definition multiplexed analog signal so that the selected group is the one that provides picture information which fits the aspect ratio of the display. The selected samples for one scan line are first stored during the active scan line time and then read out sequentially during the subsequent scan line time. The stored samples of each component signal are read out sequentially during substantially the same time period to provide the required Y, U, V signals. A similarly designed demultiplexer may be used to process an extended aspect ratio frequency multiplexed signal such as a high definition NTSC-formatted signal.

摘要： High horizontal spatial frequency information may be transmitted through a limited bandwidth channel by means of spatial-temporal frequency interleaving techniques. To transmit both frequency interleaved high horizontal spatial frequency information and diagonal spatial frequency information in one video signal, the corresponding spectra containing these two types of information are time-multiplexed prior to transmission. At the receiver, the interleaved high horizontal frequency information is extracted, relocated to its original horizontal position, and recombined with the diagonal frequency information to generate a baseband video signal.

摘要： 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.
