摘要： To effectively eliminate cross-talk between the weak signals picked up by a tape transducer pick-up head with signals being applied to a recording head, a disk-like headwheel carrier has a disk-like headwheel secured thereto. The disk-like headwheel carrier is formed with a recess which defines a chamber (6) in which the preamplifier for the reproduced signals is placed. Transducer leads are passsed in a channel duct formed between the headwheel carrier and the disk-like headwheel, which is in plate form. Preferably, both the disk-like headwheel as well as the carrier are made of lightweight metal, such as aluminum, so that the reproducing amplifier is totally shielded. The recording amplifier can be placed on top of the disk-like headwheel, separated and shielded from the reproducing preamplifier.

摘要： For reliable playback of digital video signals in slow-motion operation over a wide range of slow-motion speeds, auxiliary playback heads are positioned closely behind normal playback heads and offset by half a track width therefrom. Each of the playback heads have a circuit for regenerating clock and data signals which includes a PLL circuit and all of the PLL circuits have an output for the signal that shows whether the PLL circuit is locked in or not. The lock-in signals are supplied to first address inputs of an ROM which has a principal output showing whether the normal playback heads or the auxiliary playback heads have the larger number of locked-in PLL circuits and the group of playback heads having that larger number of locked-in PLL circuits is selected for having the data and clock signal outputs passed on to playback channels for further processing. The control of the switching circuit is improved by having auxiliary outputs of the ROM fed back to second address inputs thereof.

摘要： Digital color television signals intended to be recorded in serial bit form are first subjected to predistortion to compensate for nonlinear distortion digitally computed for each serial bit on the basis of the pattern established by a predetermined number of precursor bits, which requires digital to analog conversion of the multibit parallel output of the predistortion computation. The converted output is then filtered on an analog basis to compensate for linear distortion, as by emphasizing the higher frequencies. In reproduction, the similar combination of analog and digital distortion compensation is used, first filtering and then, after retrieving the bit clocking frequency and phase, analog to digital conversion and compensation for nonlinear distortion by programmed interpretation of a parallel multibit input to select correctly the bits of an output serial bit stream. The latter can be subjected to conversion into the usual eight bit parallel color television signals. The combination of both programmed digital distortion compensation and analog compensation of linear distortion not only reduces the output bit error rate, but has the advantages of being adaptive in that a test bit sequence can be used to select the most effective program for correcting nonlinear distortion for a particular system of recording channel, record medium and reproduction channel, provided that the nonlinear distortion compensators use RAMs, so that the best variety of nonlinear distortion correction for a particular equipment and/or tape can quickly be selected.

摘要： In the transmission of a television signal containing a luminance signal between a transmitting station and a receiving station of a television system, the picture resolution at the receiving station is compatibly increased by: effecting planar prefiltering of the luminance signal at the transmitting station and a corresponding planar postfiltering of the luminance signal at the receiving station; effecting offset sampling or offset modulation of the luminance signal at the transmitting station and a corresponding sampling conversion or demodulation of the luminance signal at the receiving station; deriving an additional signal from the luminance signal for increasing picture resolution, reducing the amplitude of the additional signal at the transmitting station and transmitting the additional signal together with the original luminance signal to the receiving station; and increasing the amplitude of the additional signal at the receiving station to an extent corresponding to the reduction performed at the transmitting station.

摘要： A method of correcting picture steadiness errors (or film weave correction) in telecine scanning is proposed, in which, in a first step, at least one sample area of the picture contents of the video signal obtained by film scanning is determined by way of structure recognition, this sample area corresponding to a curvature in the picture contents. In a second step, it is checked, by way of comparison, whether the determined sample areas are recognizable in a search area of the sequential frame. In a third step, motion vector signals are generated when the sample areas are recognized again in the sequential frame, these motion vector signals defining the direction of motion and the extent of deviation of the position of the determined sample area from the position of the recognized sample area. In a fourth step, parameters of a transform function are determined by the motion vector signals. In a subsequent fifth step, motion vectors, which correspond to partial motions, are recognized and eliminated by comparing the transform function with the motion vectors. Steps four and five are performed several times, if necessary. In a sixth step, correction signals are derived by taking the temporal sequence of transform functions into account, and in a seventh step, these correction signals are applied to a control device, these correction signals correcting the stability errors in the picture signals.
