Abstract

A method and apparatus for a composite video apparatus can reduce or prevent an image distortion of a composite video apparatus. When a progressive scanning video signal of the composite video apparatus is output to a display device, an on-screen display signal indicating the progressive scanning video signal is generated and output to the display device.

Claims

1. A method for outputting a video signal of a composite apparatus comprising:

generating a display signal indicating a progressive scanning video signal when the progressive scanning video signal of a composite video apparatus is selected for output to a display device; and

outputting the generated display signal to the display device.

2. The method of claim 1, wherein the display signal is in an interlaced scan format.

3. The method of claim 1, wherein the outputting the generated display signal comprises outputting a generated on-screen display signal and the progressive scanning video signal together to the display device.

4. The method of claim 3, wherein the outputting the generated display signal comprises outputting a generated on-screen display signal before a title and video data of the progressive scanning video signal is outputted to the display device.

5. The method of claim 1, further comprising:

converting the progressive scanning video signal into an interlaced scanning video signal when the output video signal of the composite video apparatus is the progressive scanning video signal; and

outputting the converted interlaced scanning video signal to the display device.

6. The method of claim 5, wherein the outputting the generated display signal comprises outputting a generated on-screen display signal before the converted interlaced scanning video signal is outputted to the display device.

7. The method of claim 1, wherein the composite video apparatus is a tape player/optical disk player composite apparatus.

8. The method of claim 6, wherein the composite video apparatus is at least one of a VCR/DVDP composite apparatus and a VCR/DVDR composite apparatus.

9. The method of claim 1, comprising:

generating an additional display signal indicating a selection of an output a progressive scanning video signal or a corresponding interlaced scanning video signal; and

outputting the selected video signal in the selected video scan format to the display device.

10. The method of claim 9, wherein the outputting the generated display signal comprises outputting a generated on-screen display signal before the selected video signal is outputted to the display device.

11. The method of claim 9, wherein a user performs the selection of the progressive scanning video signal and the corresponding interlaced scanning video signal.

12. The method of claim 9, wherein the additional display signal is an on-screen display generated in an interlaced scan format.

13. The method of claim 9, wherein the display signal and the additional display signal are combined.

14. The method of claim 9, wherein the additional display signal is an on-screen display (OSD) generated in one of the progressive scan format and the interlaced scan format.

15. The method of claim 14, wherein a user performs the selection of the progressive scanning OSD signal and the corresponding interlaced scanning OSD.

16. The method of claim 15, wherein the user performs the selection of the progressive scanning video signal and the corresponding interlaced scanning video signal.

17. An apparatus configured to output a video signal of a composite apparatus, wherein when a progressive scanning video signal of a composite video apparatus is selected for output to a display device, a display signal indicating the progressive scanning video signal is generated, and the generated display signal is outputted to a display device.

18. The apparatus of claim 17, wherein the composite video apparatus is a VCR/DVDP composite apparatus, and wherein the generated display signal is an on-screen display signal in interlaced scanning format.

19. The apparatus of claim 18, wherein when an output video signal composite apparatus is the progressive scanning video signal, the output video signal is one of (1) converted into an interlaced scanning video signal and (2) outputted as the progressive scanning video signal with the generated on-screen display signal.

20. The apparatus of claim 19, wherein the on-screen display signal indicating the progressive scanning video signal is outputted before a title and data of the progressive scanning video signal.

21. The apparatus of claim 18, wherein an additional display signal is generated providing for selection of the output signal in the progressive scanning video format or an interlaced video format, and wherein the output signal is outputted in the selected format.

22. A composite apparatus, comprising:
