Abstract

A combination system capable of controlling output signals and a method of controlling the same. The combination system includes a first device for generating first analog audio/video signals by reproducing data recorded on a first recording medium, a first signal converting unit for converting the first analog audio/video signals to first digital audio/video signals and outputting the same, and a second device for generating second digital audio/video signals by reproducing data recorded on a second recording medium, and outputting either the first or second audio/video signals through selection, and converting a scanning format of the selected video signal. A user of the combination system is able to enjoy high quality screen images and high quality sound because the A/V signals are supplied to a digital TV after the analog A/V signals output from a VCR of the combination system are converted to digital A/V signals.

Claims

1. A combination video reproduction and playback system, comprising:

a first device for generating first analog audio/video signals by reproducing data recorded on a first recording medium,

a first signal converting unit for converting the first analog audio/video signals into first digital audio/video signals and outputting the first digital audio/video signals, and

a second device for generating second digital audio/video signals by reproducing data recorded on a second recording medium, and outputting either the first or second digital audio/video signals as selected digital audio/video signals.

2. The combination video reproduction and playback system according to claim 1, wherein the second device comprises a converter for converting a scanning format of the selected video signal.

3. The combination video reproduction and playback system according to claim 2, further comprising:

an image encoding device, for encoding the scanning format converted selected video signal to change the selected video signal from a digital video signal to a displayable signal format.

4. The combination video reproduction and playback system according to claim 3, wherein the displayable signal format comprises either a RGB video signal or a YCbCr video signal.

5. The combination video reproduction and playback system according to claim 1, wherein the first device comprises:

a VCR video processing unit; and

a VCR audio processing unit.

6. The combination video reproduction and playback system according to claim 1, wherein the first signal converting unit comprises:

a first video analog-to-digital converter; and

a first audio analog-to-digital converter.

7. The combination video reproduction and playback system according to claim 1, wherein the second device comprises:

a digital audio selection unit for receiving the first and second digital audio signals and selecting either the first or second digital audio signals; and

a digital video selection unit for receiving the first and second digital video signals and selecting either the first or second digital video signals.

8. The combination video reproduction and playback system according to claim 7, further comprising:

a scanning format unit for receiving the selected digital video signal and formatting the digital video signal.

9. The combination video reproduction and playback system according to claim 8, wherein the scanning format unit formats the digital video signal from an interlaced scanning format to a progressive scanning format.

18. The method for operating a combination video reproduction and playback system according to claim 1, further comprising converting a scanning format of the selected video signal.

19. The method for operating a combination video reproduction and playback system according to claim 18, further comprising:

encoding the converted scanning format selected video signal to change the selected video signal from a digital video signal to a displayable signal format.

20. The method for operating a combination video reproduction and playback system according to claim 19, wherein the displayable signal format comprises either a RGB video signal or a YCbCr video signal.

10. A method for controlling a combination video reproduction and playback system, comprising:

selecting a reproducing mode by a user;

determining whether the selected reproducing mode is a VCR reproducing mode;

converting a first analog audio/video signal into a first digital audio/video signal if the selected reproducing mode is a VCR reproducing mode; and

providing a peripheral device with a converted scanning format first digital audio/video signal.

11. The method for controlling the combination video reproduction and playback system according to claim 10, wherein the providing step comprises:

selecting the first digital audio/video signal instead of a second digital audio/video signal;

converting a scanning format of the first digital audio/video signal from a first scanning format to a second scanning format; and

outputting the second scanning format first digital signal through a second video output terminal to a peripheral device.

12. The method for controlling the combination video reproduction and playback system according to claim 11, wherein the first scanning format is an interlaced scanning format, and the second scanning format is a progressive scanning format.

13. The method for controlling the combination video reproduction and playback system according to claim 11, wherein the peripheral device includes a digital television.

14. The method for controlling the combination video reproduction and playback system according to claim 10, further comprising:

decoding a second digital audio/video signal if the selected reproducing mode is not a VCR reproducing mode;

selecting a second digital audio/video signal instead of a first digital audio/video signal;

converting a scanning format of the second digital audio/video signal from a first scanning format to a second scanning format; and

outputting the second scanning format second digital signal through a second video output terminal to a peripheral device.

15. The method for controlling the combination video reproduction and playback system according to claim 14, wherein the first scanning format is an interlaced scanning format, and the second scanning format is a progressive scanning format.

16. The method for controlling the combination video reproduction and playback system according to claim 14, wherein the peripheral device includes a digital television.

17. A method for operating a combination video reproduction and playback system, comprising:

generating a first analog audio/video signal by reproducing data recorded on a first recording medium, converting the first analog audio/video signals into first digital audio/video signals and outputting the first digital audio/video signals, and generating second digital audio/video signals by reproducing data recorded on a second recording medium; and

outputting either the first or second digital audio/video signals as selected digital audio/video signals.

21. The method for operating a combination video reproduction and playback system according to claim 17, wherein the step of generating a first analog audio/video signal comprises:

operating a VCR video processing unit and a VCR audio processing unit to produce the analog audio/video signals.

22. The method for operating a combination video reproduction and playback system according to claim 17, wherein the step of converting the first analog audio/video signals comprises:

operating a first video analog-to-digital converter and a first audio analog-to-digital converter to produce the first digital audio/video signals.

23. The method for operating a combination video reproduction and playback system according to claim 17, further comprising:

receiving the first and second digital audio signals and selecting either the first or second digital audio signals; and

receiving the first and second digital video signals and selecting either the first or second digital video signals.
