    摘要: A wide aspect signal is band-width limited in the vertical spatial frequency by a V-LPF. The wide aspect signal is band-width limited along the temporal spatial frequency and in the vertical and horizontal spatial frequency by a 1/60-sec delay unit, an adder, 1 1/60-sec delay unit, a selector, a V-LPF, and an H-LPF. A motion image signal can be obtained by an adder. A still image signal can be obtained by the selector. The motion and still image signals are mixed by a mixer in accordance with an image motion amount. An output from the substractor is processed by a vertical shifter, an H-LPF, and a 6.fwdarw.5 converter to provide a still image compensation signal Vh. A signal from the V-LPF is compressed in the vertical direction by a 6.fwdarw.5 converter so as to be a center portion signal which can be displayed as an image with the receiver of the existing television system, and supplied to a selector. An output signal from the 6.fwdarw.5 converter is processed by an LD generator to generate a motion image compensation signal (LD signal). The LD and Vh signals are selectively output from a mixer in accordance with the image motion. A compensation signal output from the mixer is processed by an H-LPF, a 1/5-time compressor, and a rearranging unit, so that it can be multiplexed on upper and lower black bar portions formed on upper and lower portions of the center panel, and supplied to the selector.

    摘要: A first image signal for a screen wider than that obtained by a TV signal of an existing television system is converted to a multiplexed signal that can be reproduced with a receiver of the existing television system, and input to a selector. The selector divides the input signal into a center portion signal and upper and lower black bar portions signals of the screen. The multiplexed signal has a center portion signal as an image display portion and upper and lower black bar portion signals as non-image portions. A difference signal (first LD signal) is multiplexed on the upper and lower black bar portion signals. A rearranging unit, a 5-time expander, a double speed converter, a delay unit, and a selector reproduce the first LD signal from the upper and lower black bar portion signals. A delay unit and a double speed converter double-speed convert the center portion signal. A line interpolator and a selector generate a progressive scanning signal. A 5.fwdarw.6 converter expands the progressive scanning signal in the vertical direction. The first LD signal is added to the interpolated scanning line of the first field by an adder. An LD generator generates a second LD signal from the compensated progressive scanning signal in the same manner as on the transmission side. A line interpolator and a selector also generate a progressive scanning signal. The second LD signal is added to the interpolated scanning line of the second field by an adder.

    摘要: In a band compression apparatus, an input signal is separated into high- and low-frequency components H and L by an LPF and an adder. The component H is in-frame-averaged by an in-frame average circuit. The component L is output as a signal S.sub.3 having a large energy via a field delay circuit and a switch circuit. An in-frame difference of the low-frequency component L is obtained by a field delay circuit and an adder. This in-frame differential signal S.sub.2 is added to an in-frame average signal S.sub.1 by an adder. A signal S.sub.4 having a small energy is obtained by this addition. In a band restoration apparatus the signals S.sub.3 and S.sub.4 are separated into signals of two fields by an adder and a switch circuit. A signal S.sub.5 consisting of the components L and H is obtained in one field. A signal S.sub.2 consisting of only the component L is obtained in the other field. The signal S.sub.5 is output via a switch circuit. The signal S.sub.2 is added to the signal S.sub.5 in an immediately preceding field by an adder. A signal S.sub.6 consisting of the components L and H is obtained by this addition. The signal S.sub.6 is output via the switch circuit at a timing delayed by one field with respect to the signal S.sub.5.

    摘要: A television signal multiplexing and demultiplexing system includes a signal separation circuit for separating from a composite color television signal a plurality of first television signals serving as additional information for making the quality of a television picture higher and a second television signal. A matrix operation circuit performs a vertical matrix operation on the first television signals so as to dispose each of the first television signals in a different vertical band, thereby producing operation outputs. A delay circuit delays the operation outputs by different amounts of delay to produce delayed outputs. A multiplexing circuit multiplexes the delayed outputs on different horizontal scanning lines of the second television signal to produce a multiplexed output. A demultiplexing circuit demultiplexes the multiplexed output into the operation outputs and the second television signal. A recovering circuit recovers the first television signals by performing a matrix operation which is the inverse of the matrix operation on the separated operation outputs to recover the first television signal.

    摘要: The present invention is ingeniously conceived for a transmission system for a first television signal so as to enable a first television signal of a wide aspect screen to be transmitted in one channel and the transmitted television signal to be reproduced on a receiver of a conventional aspect screen. To this end, a screen dividing circuit (12) divides a wide aspect screen signal into a center panel signal and side panel signals. The center panel signal is supplied via a delay circuit (13) to an adder (16). The side panel signals are so allocated as to provide horizontal and vertical signals. The horizontal side signal is supplied via a horizontal overscan multiplexing circuit 16 to the adder (16) where it is multiplexed on a horizontal overscan area of the center panel signal. In the vertical overscan multiplexing circuit, the vertical side signal is time compressed and reverse processed for each line to provide it in a continuous form. The output of a vertical overscan multiplexing circuit (20) is supplied to a switch (18) where it is time division multiplexed on vertical overscan areas of the center panel signal which is sent from the adder (16) via a delay circuit (17).

    摘要: A transmission device includes reference signal generator (204) generates a transmission instruction for DMRS or SRS produced by base station (100), and an RS that corresponds to a transmission instruction in the DMRS and SRS on the basis of identification information of an RS pattern used in the DMRS and SRS and set in base station (100). Transmission signal formation unit (207) maps the generated RS to a time frequency resource. The RS pattern of the DMRS and the RS pattern of the SRS have a relationship in which the RS pattern of the SRS is obtained by adding the length of a CS series/4 to the cyclic shift amount, which is an element of the CS series pattern, in the RS pattern of the DMRS, and inverting the identification information of a first Walsh series or a second Walsh series, which are constituent elements of an OCC pattern.
