Abstract: An information converting method of converting audio information, which comprises a plurality of partial-audio information based on a predetermined record standard in each of which output control information to control a state of the audio information at a time of outputting the audio information to an external portion is included, into transmission information to be transmitted through a data bus based on a predetermined transmission standard, is provided with: an extracting process of extracting the output control information from each of the partial-audio information; a dividing process of dividing the audio information for each information amount, which is set in advance so as to transmit the transmission information through the data bus, to thereby generate divided-audio information; a generating process of adding the extracted output control information onto the generated divided-audio information to thereby generate an information unit for transmitting the audio information through the data bus; and an

Abstract: An audio information reproducing apparatus for reproducing audio information on a recording medium, which can be connected with a bus. In the medium reproducing control information for controlling a reproducing mode of the audio information and the audio information are recorded. The reproducing control information has an amount of information larger than that capable of being inserted into one information unit formed during transmission via the bus. In the apparatus a detecting device detects the audio information and the reproducing control information from the medium. Then, a generating device generates corresponding information indicating a corresponding relationship between the audio information and the reproducing control information.

Abstract: In a video-audio synchronizing method for synchronizing video and audio reproduced respectively by a monitor 300 and an amplifier 400 connected to a serial bus 100 to which video from a DVD player 200 and audio associated with the video are supplied, the monitor 300 sends out delay time information caused by an intrinsic delay element for video display to the amplifier 400 through the serial bus 100 as a control command, and the amplifier 400 delays the audio by time necessary for synchronization between the video and the audio according to the control command and outputs the audio.

Abstract: In a video disk player, internal and external synchronization are based on comparing the phases of reproduced and reference pulses. The controlled frequencies responsive to the phase difference are controlled at 4f.sub.sc, where f.sub.sc is the color subcarrier frequency. The control loop for controlling the spindle speed, and therefore setting the synchronization of the read out, operates on the 4f.sub.sc signal, which is frequency divided on the same integrated chip as the spindle servo electronic, to provide the horizontal synchronization control.

Abstract: A reproducing processor for processing a video format signal and allowing, during dropout, selective inhibition of at least one of dropout compensation and video signal correction processing, for preventing production of uncorrectable errors due to a processsing of digital data of the video format signal. Included are: a dropout compensation component for carrying out dropout compensation for a video format signal obtained from the reproducing component in the absence of a digital data signal reproducing command, and not carrying dropout compensation in response to the digital data signal reproducing command; and a signal selection component for selectively outputting an output of a waveform shaping component in response to the digital data signal reproducing command, and for selectively outputting an output of a signal processing component in the absence of the digital data signal reproducing command.

Abstract: A video signal processing circuit processes a digital video signal to provide a stereoscopic video signal which can be presented without flicker and without reduced recording time. Digital video fields are consecutively stored in three memories or storage location of a memory, each new field replacing the oldest one. The fields are stored at a first clock rate. The stored video is read out at twice the first rate with each successive pair of fields being read out twice.
