Abstract
To provide a video signal processing apparatus capable of generating video signals that enable displaying and recording of a high-quality picture. A video signal processing apparatus according to an embodiment of the present invention includes a decoder decoding an input TS to generate a video signal having a field frequency fv of 60 Hz or a video signal having a field frequency fv of 59.94 Hz, and a converter converting the respective video signals into NTSC video signals having a color subcarrier the phase of which is inverted for each frame.
Claims15
A video signal processing apparatus, comprising:
- a decoder decoding an input video signal to generate a first standard video signal and a first non-standard video signal;
- and
- a converter converting the first standard video signal with a first color subcarrier frequency into a second standard video signal of which a color subcarrier inverts a phase for each frame, and converting the first non-standard video signal with a second color subcarrier frequency into a second non-standard video signal of which a color subcarrier inverts a phase for each frame.
A video signal processing method, comprising:
- decoding an input video signal to generate a first standard video signal and a first non-standard video signal;
- converting the first standard video signal with a first color subcarrier frequency into a second standard video signal of which a color subcarrier inverts a phase for each frame;
- and
- converting the first non-standard video signal with a second color subcarrier frequency into a second non-standard video signal of which a color subcarrier inverts a phase for each frame
A video signal processing apparatus, comprising:
- an ATSC decoder decoding an input ATSC video signal;
- an NTSC encoder encoding the decoded signal with a color subcarrier frequency into an NTSC video signal;
- and
- a determining section determining the color subcarrier frequency in accordance with a field frequency of the ATSC video signal in such a manner that frames of the encoded NTSC video signal are interleaved.
