    摘要： A motion picture film having digital audio data recorded in at least one sound track thereof. Such digital audio data includes a plurality of bytes of data each having 8 bits of data. Each respective bit of each byte of audio data is recorded in a sound track of the film in the film running direction and each byte is arranged side-by-side in a direction normal to the film running direction to form a compression processing block. C1 parity data is added to each such compression processing block and C2 parity data is added after a predetermined interval of plural compression processing blocks. Error correction may be performed by utilizing the C1 and C2 parity data for each compression processing block and at the predetermined interval of plural compression blocks.

    摘要： A main memory stores a signal reproduced from a recording medium with a time base error, and a read clock generator and phase modulator generates a read clock signal of variable phase for reading out the signal from the main memory. A velocity compensating circuit generates first discrete signals representative of the velocity error of the reproduced signal at designated sample points of a current field and second discrete signals representative of a velocity error of the reproduced signal at sample points of a previous field respectively corresponding to the designated points and interleaves the first and second discrete signals to produce a combined signal having a sampling frequency greater than that of either the first or second discrete signals. The combined signal constitutes a nonlinear approximation of the time base error, and the read clock generator and phase modulator is responsive to the combined signal for controlling the readout of the reproduced signal from the main memory in such a manner as substantially to eliminate the time base error.

    摘要： In a magnetic reproducing apparatus for reproducing a luminance signal and timebase-compressed chrominance component signals recorded on separate tracks of a record medium, the reproduced chrominance component signals are directly supplied to a timebase expander and this timebase expander uses a reference clock which reference clock is employed in the timebase correction of the luminance signal and frequency-divided by the timebase compression ratio whereby to perform the timebase expansion and the timebase correction at the same time. Thus, it is not necessary that the timebase correction and the timebase expansion are performed by separate circuits and this leads to a simple circuit arrangement.

    摘要： When an operator operates an operation tool of a dimming operation terminal device in order to set the brightness of a lighting load to desired brightness, an energization electric signal, for example, a voltage level detected by a dimming control section changes. The dimming control section generates a dimming signal modulated according to the voltage level. Power supply to the dimming control section is performed by an insulated auxiliary power supply. Transmission of the dimming signal is performed via an insulating section.
