Abstract: A received television broadcasting signal is always recorded to a hard disk. In the hard disk, by time-divisionally processing the recording and reproduction, they are executed in parallel. In the television broadcasting, when the user wants to see a video image which has already become a past image, a high speed reverse rotation reproduction is instructed by the user. The video image is switched from the video image by the television broadcasting to the reproduction video image reproduced from the hard disk. The user designates the reproducing position while seeing the video image reproduced by the reverse rotation. The forward rotation reproduction is started from the designated position. When a scene which the user wants to see is finished and the forward rotation reproduction is cancelled by the user, the video image is switched from the reproduction video image to the video image of the television broadcasting.

Abstract: A recording and reproducing apparatus is disclosed which is capable of accurately recording and reproducing an image signal and an audio signal to and from a disk even if a non-standard image signal has been supplied, the recording and reproducing apparatus having a storing unit for temporarily storing the audio signal to be recorded on a rewritable-disk-type recording medium and for outputting storage information which is information of the quantity of stored audio signals. A recording/reproducing unit changes the number of sectors of the disk type recording medium within a predetermined number of sectors to record the audio signal stored in the storage unit in synchronization with the image signal. A memory unit memorizes information of the sectors of the disk type recording medium on which the audio signals have been recorded as management information.

Abstract: A video signal processing apparatus which includes a clock signal generator for generating a clock signal in synchronism with a color synchronizing signal contained in an incoming video signal. This clock signal has a frequency equal to a multiple of the frequency of the color synchronizing signal. An analog-to-digital converter operates in response to the clock signal to sample and convert an incoming composite video signal into a digital video signal. An address setting circuit is provided for generating an address signal synchronized with horizontal and vertical synchronizing signals.
