摘要： A digital encoder for use in both NTSC and PAL systems includes a demultiplexer for separating a time-division color difference signal R-Y/B-Y into color difference signals R-Y and B-Y. The separated color difference signals R-Y and B-Y are converted by a sub-carrier frequency converter into a sub-carrier frequency, and a digital modulator determines levels and phases of the converted color difference signals. A burst generating circuit generates a burst signal after determining a level and phase of the burst signal, and a chroma encoder produces a chroma signal by mixing an output of the digital modulator with the burst signal.

摘要： A signal processing device is arranged to form a first output modulated signal by modulating an input information signal in accordance with a modulation carrier signal, to form a second output modulated signal by modulating the first output modulated signal in accordance with a modulation carrier signal which is identical to the above-stated modulation carrier signal, and to correct the input information signal by using the second output modulated signal. The modulation circuit of the device is thus arranged to have a minimal amount of leakage of the modulation carrier signal for the information signal, so that the device can be easily arranged as an integrated circuit.

摘要： In a color television camera apparatus, a 2fs-rate luminance signal and fs-rate chrominance signals are selectively generated by a matrix circuit 8, in conformity with a plurality of standard systems, from 2fs-rate three-color image pick-up signals generated by an image signal pick-up unit. The fs-rate chrominance signals are modulated by a modulating circuit 12 into fs-rate modulated chrominance signals which are converted by a rate converter 13 into 2fs-rate modulated chrominance signals. The 2fs-rate luminance signals and the 2fs-rate modulated chrominance signals are combined by an adder 14 into 2fs-rate digital composite video signals which are converted by a D/A converter 15 into analog composite video signals. In this manner, analog composite video signals, in which the bandwidth of the luminance signals has been enhanced up to the sampling frequency fs, may be selectively outputted in conformity with a plurality of standard systems.

摘要： A digital processing color camera includes a matrix circuit for arithmetically processing digital R, G and B video signals, which have been sampled by a clock signal, to provide a digital brightness signal, a first digital color difference signal and a second digital color difference signal. Those signals are subsequently converted by associated digital-to-analog converters into an analog brightness signal, a first analog color difference signal and a second analog color difference signal. Both the brightness signal and the first color difference signal, are delayed a predetermined period of time by digital delay lines inserted between the matrix circuit and the digital-to-analog converter circuit.

摘要： The phase of an output subcarrier signal may be varied over a range of 360.degree. with respect to the phase of an input subcarrier signal. A ramp generator which generates a ramp at one-half the subcarrier frequency, is coupled to a very fast differential comparator means whose output causes a subsequent tuned circuit to ring at the subcarrier frequency. Continuous oscillations, recycled every second subcarrier cycle, are generated as determined by the threshold set on the differential comparator means. A crystal filter reproduces the output subcarrier as a clean sinewave. Remotely controlled phase adjustment of from zero to 360.degree. is provided by varying the threshold of the differential comparator.

摘要： A cost-effective apparatus and method for equalizing signals (e.g., TMDS signals) is presented. The apparatus includes a housing and an input connector and an output connector on the housing. An equalizer chip inside the housing receives input pixel signals from the input connector and transmits output pixel signals through the output connector. An buffer (e.g., an I2C buffer), which is also located inside the housing, receives input control signals (e.g., input I2C signals) from the input connector and transmits output control signals (e.g., output I2C signals) to the output connector. The apparatus may be operated in single-link or dual-link mode. A copper cable connecting a DVI signal source to the input connector may be as long as 60 meters without causing noticeable signal deterioration.

摘要： A multiple-format video encoder stores values of the sine and cosine functions in a ROM. According to the externally specified video format, an address calculating circuit calculates the addresses at which to access the ROM. In the multiple-format video encoder, a luminance/color-difference signal generating circuit generates color-difference signals B-Y and R-Y from digital RGB signals. A first multiplying circuit multiplies the color-difference signal B-Y by the values of the sine function stored in the ROM at the addresses specified by the address calculating circuit and multiplies the color-difference signal R-Y by the values of the cosine function stored at the same addresses.
