摘要： Recording/reproducing apparatus including recording electronics and playback electronics and a radio receiver responsive to a selected television signal for supplying a composite video signal to the recording electronics at selected times are contained within a unitary package designed to rest on a surface. A video camera supplies composite video signal for selective application to the recording electronics at other times, the supplying of those composite video signals to said recording electronics being done by means other than cabling from the video camera to the unitary package. The video camera is included within the same unitary package as the magnetic recording/reproducing apparatus in some systems, thus to eliminate cabling from the video camera to the unitary package. In other systems designed for photorecording without the need for an operator to attend the camera, the video camera is included with a low-power radio transmitter in a separate package from the unitary package including the magnetic recording/reproducing apparatus and the radio receiver. The low-power radio transmitter is designed to transmit the composite video signal from the video camera by wireless link to the radio receiver within the same unitary package as the magnetic recording/reproducing apparatus, thereafter to be recorded.

摘要： Digital signal receivers for detecting BPSK modulation of a suppressed carrier transmitted through the same channel as an analog television signal are described, in which the detected BPSK is digitized with an oversampling analog-to-digital converter prior to digital comb filtering for separating the BPSK from interfering analog television signal remnants. This is done to get an increased number of bits resolution from a relatively inexpensive flash converter so that the BPSK, which is of relatively low amplitude compared to maximally interfering analog television signal remnants, is not overwhelmed by quantizing noise. The oversampling analog-to-digital converter can be of sigma-delta type.

摘要： An NTSC television signal transmitter also transmits through the same transmission channel a suppressed data carrier having a frequency differing from that of video carrier, having a symbol rate that is a multiple of horizontal scanning rate of video signal, having data frames occurring at a data frame rate that is the same as the video frame rate, and transmitting the symbols transmitted in each of alternate data frames in opposite phase during the next data frame. The data carrier has no image on the other side of the video carrier and preferably its modulation spectrum overlaps the video carrier. A receiver recovers data from such a data carrier buried in an NTSC television signal, using frame-comb filtering to separate data from interfering video signal.

摘要： A current minor amplifier (CMA) includes first, second, third and fourth field effect transistors (FETs), all of the same conductivity type. The first and second FETs are in nested cascode connection in the CMA input stage, and the third and fourth FETs are in nested cascode connection in the CMA output stage. The drains of the second and fourth FETs respectively connect to the CMA input terminal and to the CMA output terminal, and the sources of the first and third FETs connect to the CMA common terminal. The potential at the CMA input terminal is applied to an interconnection of the gate electrodes of the first, second, third and fourth FETs to regulate current conduction through their channels, thereby to implement CMA operation. Structural differences between the first and second FETs cause the first FET source-to-gate voltage to exceed the second FET source-to-gate voltage in response to serial conduction of current through their respective channels; and similar structural differences between the third and fourth FETs cause the third FET source-to-gate voltage to exceed the fourth FET source-to-gate voltage in response to serial conduction of current through their respective channels. These structural differences can involve different dopings of the semiconductor regions in which the serially connected FET channels in each nested-cascode connection are respectively induced, or differences in the width-to-length ratios of the serially connected FET channels in each nested-cascode connection, or both such differences.

摘要： A field transfer imager is erased after every field transfer, prior to a new field of pixels-descriptive charge packet being accumulated in the successive charge transfer stages of the charge transfer channels of the image register. The image register is operated to supply a field of "null" charge packets for each field of pixel-descriptive charge packets it supplies. The "null" charge packets and pixel-descriptive charge packets are temporarily stored in respective field storage registers, and converted a line at a time to serial format for sensing. The resulting "null" samples and pixel-descriptive samples are differentially combined to provide pixel-descriptive samples with suppressed dark current ramp components and, assuming field-rate shuttering of the imager is not used, with suppressed transfer smear components.

摘要： Color signal samples generated by CCD imagers used with a color stripe filter normally exhibit hue errors owing to cross-color components in the samples arising from misalignment of the color striped imager on the imager elements. These cross-color components are suppressed in the invention, by re-sampling the color signals.
