Reference numeral 12 denotes a data sequential reading unit which converts the parallel digital information signal applied from the data storage unit 11 into a serial digital information signal and sequentially reads out the serial digital information signal.

A video encoder 13 adds a synchronization signal to the digital information signal to synthesize a video signal. Reference numeral 14 denotes a synchronization signal generating section that generates a synchronization signal necessary for the video signal. 1
Reference numeral 5 denotes a timing signal generating section which, in synchronization with the synchronizing signal sent from the synchronizing signal generating section 14, supplies a read control signal and a read address signal to the data storage section 11, and a parallel digital signal to the data sequential reading section 12. Each transmits a shift pulse that converts the information signal into a serial digital information signal.

In this configuration, the timing signal generating section 15 reads a desired information signal from the data storage section 11 using the synchronizing signal sent from the synchronizing signal generating section 14 as a reference signal. The read parallel digital information signal is converted into a serial digital information signal by the data sequential reading section 12. The video encoder 13 adds the synchronization signal sent from the synchronization signal generation section 14 to the serial digital information signal sent from the data sequential reading section 12 to synthesize a video signal. A video signal in which an information signal is encoded in the form of a digital signal is called a digital video signal, as opposed to a normal analog video signal such as an image signal.

In FIG. 4, 21 is an input terminal for a digital video signal. 22 is a synchronization signal separation unit that separates the synchronization signal from the digital video signal.

A sampling section 23 samples and extracts the digital information signal in the digital video signal. A data reproducing unit 24 reproduces the serial digital information signal into a parallel digital information signal necessary for storage and information processing. 25 is a storage section in which this information signal is stored. 26
is a processing circuit that performs predetermined processing according to the program and data read out from the storage section 25. Reference numeral 27 denotes a timing signal generation section, which uses the synchronization signal from the synchronization signal separation section 22 as a reference signal, supplies a sampling pulse to the sampling section 23, a shift clock to the data reproduction section 24, and an address signal and an address signal to the storage section 25. Write control signals are sent to control the operations of these parts.

In this configuration, when a digital video signal is input to the input terminal 21, the digital information signal in the digital video signal is sampled by the sampling section 23,
It is output as binary serial digital information. The data reproducing unit 24 receives this serial digital information signal,
The data is reproduced into parallel digital information signals handled by the storage unit 25 and the processing circuit 26 and stored in the storage unit 25. Each of these operations is controlled by the timing generator 27.

The processing circuit 26 reads information signals, ie, programs, data, etc. from the storage unit 25 and performs predetermined processing.

In this way, in the conventional technology, when loading an information signal such as a program or data into an information processing device that uses a video signal as an input source, a digital video signal in which the information signal is encoded in a digital signal format is used. was. For this reason, in the case of an information processing device that uses an analog video signal as an input source, it is necessary to separately install a dedicated decoding device to decode the information signal from the digital video signal and load programs, data, etc. was there.
