Abstract: A digital sine wave signal is read form a memory storage of a phase synchronizing apparatus and is converted into an analog signal through a digital to analog converter. This converted analog sine wave is phase compared to an input analog sine wave supplied to an input terminal of the synchronization apparatus. The phase of the digital sine wave is synchronized with that of the input analog sine wave by controlling a read address signal of the memory storage based upon a detected phase error signal between the input analog sine wave and the converted analog sine wave. Thus, a desired digital signal synchronized with the phase of an input signal can be generated by a simple arrangement by digital processing.

Abstract: When a continuous wave signal synchronized with a first color subcarrier signal is generated by a color subcarrier extracting circuit, a phase error detecting circuit, an A/D converting circuit, and a digital oscillating circuit from an analog video signal containing a first color sub carrier signal supplied to a first input terminal and a digital video signal containing a color signal component supplied to a second input terminal is converted by a digital video signal converting circuit into a composite video signal containing a carrier chrominance signal, a color signal component is converted into a carrier chrominance signal by using the continuous wave signal and a phase of a first color subcarrier signal contained in the analog video signal and a phase of a second color subcarrier signal of a composite video signal formed from the digital video signal are synchronized with each other.

Abstract: A video signal format converting circuit is disclosed, comprising a signal converting matrix circuit and a filter circuit that is constructed of a time delaying device for a video signal corresponding to a standard television format. When a digital video signal corresponding to a first video signal format is converted into a second video signal format that is different from the first video signal format and then output, the time delaying device of the filter circuit is used as a delaying circuit. The output signal of the delaying circuit or the video signal corresponding to the standard television signal format is selectively output. While or after the video signal corresponding to the first video signal format is converted into the video signal corresponding to the second signal format, the video signal is modified so as to protect it from being copied.

Abstract: A video signal processor is capable of executing on/off control of a copy inhibiting process and rendering extremely difficult any illegal cancellation of the copy inhibiting process by a third person. This video signal processor includes an obstructor for obstructing proper recording of a video signal; a memory for storing a specific code inputted when enabling the obstructor, and also for storing a disable request code inputted in response to a request for disabling the obstructor; a judge device for judging the relationship between the value of the specific code and the value of the disable request code outputted from the memory; and a decider for deciding an operation to disable the obstructor in accordance with the output of the judge means. The memory has a plurality of registers, and at least one of the bit components of the specific code and the disable request code is stored dispersedly in the plural registers in the memory.
