Abstract

An apparatus to provide digital broadcasting data using a Wireless Local Area Network (WLAN) includes: a digital broadcasting processor adapted to receive, demodulate, decode, and output multi-channel digital broadcasting data; a transcoder adapted to receive the demodulated digital broadcasting data from the digital broadcasting processor, to convert the digital broadcasting data into a format transmittable over a Wireless Local Area Network (WLAN), and to output the converted digital broadcasting data; and a WLAN processor adapted to transmit the converted digital broadcasting data to a wireless terminal device connected to the WLAN. The method includes: establishing a session using a Wireless Local Area Network (WLAN) between the multi-channel broadcasting receiver and a wireless terminal device, the wireless terminal device being connected to the multi-channel broadcasting receiver via the WLAN, in response to a wireless terminal device'"'"'s request; converting the digital broadcasting data received by the multi-channel broadcasting receiver into a format transmittable via the WLAN in response to a digital broadcasting service request from the wireless terminal device; and transmitting the converted digital broadcasting data to the wireless terminal device via the WLAN.

Claims

1. An apparatus comprising:

a digital broadcasting processor adapted to receive, demodulate, decode, and output multi-channel digital broadcasting data;

a transcoder adapted to receive the demodulated digital broadcasting data from the digital broadcasting processor, to convert the digital broadcasting data into a format transmittable over a Wireless Local Area Network (WLAN), and to output the converted digital broadcasting data; and

a WLAN processor adapted to transmit the converted digital broadcasting data to a wireless terminal device connected to the WLAN.

2. The apparatus according to claim 1, wherein the transcoder is adapted to compress the demodulated digital broadcasting data to reduce its bandwidth.

3. The apparatus according to claim 2, wherein the transcoder is adapted to compress the demodulated digital broadcasting data to reduce its bandwidth to be less than a transmission bandwidth of the WLAN connected to the wireless terminal device.

4. The apparatus according to claim 1, wherein the digital broadcasting processor comprises at least one tuner and demodulator adapted to receive the multi-channel digital broadcasting data.

5. The apparatus according to claim 4, wherein the transcoder is adapted to compress a bandwidth of the demodulated digital broadcasting data, wherein a transmission bandwidth of the WLAN connected to the wireless terminal device being compressed to be less than a value divided by the number of receivable channels in the digital broadcasting processor.

6. The apparatus according to claim 1, wherein, in response to a program information request from the wireless terminal device, the digital broadcasting processor is adapted to recompose pre-stored program information into a format displayable on the wireless terminal device and to transmit the recomposed program information to the WLAN processor.

7. The apparatus according to claim 1, wherein the wireless terminal device comprises a Personal Digital Assistant (PDA).

8. A wireless terminal device comprising:

a Wireless Local Area Network (WLAN) processor adapted to, in response to a user'"'"'s request, connect to a multi-channel broadcasting receiver that receives multi-channel digital broadcasting data via a WLAN, request the digital broadcasting data from the multi-channel broadcasting receiver, and receive the digital broadcasting data from the multi-channel broadcasting receiver; and

a digital broadcasting processor adapted to demodulate, decode and output the digital broadcasting data received by the WLAN processor.

9. The device according to claim 8, comprising a Personal Digital Assistant (PDA).

10. A method comprising:
