Signal converter and multimedia system using the same
First Claim
1. A multimedia system using signal converters, comprising:
- an image capture device, configured for capturing images, converting the captured images into a first electronic signal, and transmitting the first electronic signal through a first type transmission interface;
a first signal converter, configured for receiving the first electronic signal, modulating the first electronic signal by an orthogonal frequency-division multiplexing (OFDM) technology to obtain a second electronic signal adapted for a second type transmission interface; and
a second signal converter, configured for receiving and modulating the second electronic signal through the second type transmission interface, wherein the first type transmission interface is different from the second type transmission interface.

Abstract
In a signal converter and a multimedia system using the same, the multimedia system includes an image capture device, a first signal converter, a second signal converter. The image capture device is configured for capturing images, converting the images into a first electronic signal, and transmitting the first electronic signal through a first type transmission interface. The first signal converter is configured for receiving the first electronic signal, modulating the first electronic signal by the orthogonal frequency-division multiplexing (OFDM) technology to obtain a second electronic signal suited for a second type transmission interface. The second signal converter is configured for receiving and modulating the second electronic signal through the second type transmission interface. The first type transmission interface is different from the second type transmission interface.
