Abstract

Embodiments of a digital broadcasting transmitter-receiver and method for a portable computer can be detachably operated. A digital broadcasting transmitter-receiver for a portable computer can include a case to be attached in a bay of a main body, a main substrate installed in the case and mounted with at least a chip for receiving a digital broadcasting signal and an antenna partially within the case. An antenna body can reciprocally move to extend outside of the case or the portable computer. According to embodiments of a digital broadcasting transmitter-receiver, the digital broadcast can be watched on a conventional portable computer, and the expansibility of the portable computer can be increased because users can selectively mount the transmitter-receiver.

Claims

1. A digital broadcasting transmitter-receiver for a portable computer in which a display is folded on and unfolded with respect to an upper surface of a main body, comprising:

a case configured to mount in a bay in a side of the main body; and

an antenna configured to receive broadcasting signals with at least a portion thereof positioned within the case.

2. The digital broadcasting transmitter-receiver of claim 1, wherein the antenna includes an antenna body configured to reciprocally extend to the outside the case.

3. The digital broadcasting transmitter-receiver of claim 1, wherein an external construction of the case conforms to the bay.

4. The digital broadcasting transmitter-receiver of claim 1, wherein the bay is configured to mount an optical disk drive or an auxiliary battery.

5. The digital broadcasting transmitter-receiver of claim 1, wherein the antenna is configured for interactive broadcasting operations.

6. The digital broadcasting transmitter-receiver of claim 1, wherein the case is detachably mounted in the bay and has a size greater than ⅓

of the width of the main body.

7. The digital broadcasting transmitter-receiver of claim 1, wherein the antenna has a retracted size between ⅓

and ½

the width of the main body in the case.

8. The digital broadcasting transmitter-receiver of claim 1, wherein a substrate is installed in the case and provided with at least a chip for processing the received broadcasting signals, wherein the substrate is adjacent to a front surface of the case, and wherein the case connects at a rear surface to the main body.

9. The digital broadcasting transmitter-receiver of claim 8, wherein a prescribed distance is between the substrate and a main board of the main body.

10. The digital broadcasting transmitter-receiver of claim 1, wherein a substrate is installed toward a rear end of the case and includes a connector for electrically connecting with a main board of the main body, wherein a portion of the connector is exposed through the rear end of the case.

11. The digital broadcasting transmitter-receiver of claim 1, comprising:

a substrate installed in the case and mounted with at least a chip configured to process a digital broadcasting signal;

an antenna substrate installed in the case and mounted with a filtering chip configured to remove noise from the broadcasting signals received from the antenna; and
