[36] The second broadcast processing controller 325 sets the broadcast signal receiver
321 to the broadcast channel following the RF (UHF) remote control signal received from the RF (UHF) remocon receiver 200.
[37] The second broadcast processing controller 325 further includes functions of, following the RF (UHF) remote control signal, system configuration, menu setup, PVR (Personal Video Recorder) control, EPG (Electronic Program Guide) control.
[38] The network 10 configures a network by connecting a plurality of RF terminals 11, and the RF terminals 11 may be installed in a wall in a house (e.g., living room, room 1 ~ N) or other specific locations.
[39] The network 10 may be a pre-installed TV coaxial cable or post- installed network cable.
[40] The sub-TV receiver 20 receives the A/V remote broadcast signal via network 10, and shows a program corresponding to the A/V remote broadcast signal.
[41] Then, the operations of the multi-out broadcasting receiver system using RF remocon according to an embodiment of the present invention will be described in detail with reference to FIGs. 1 to 3.
[42] In the multi-out broadcasting receiver system using RF remocon according to the present invention, as shown in FIGs. 1 to 3, in a house or other specific location, with the set- top box 300 having the first broadcast processing module 310 and the second broadcast processing module 320, RF (UHF) remocon receiver 200 and main TV receiver 30 being positioned in [Distant_Location #1], and with the RF (UHF) remocon transmitter 100 and sub-TV receiver 200 being positioned in [Distant_Location #2], the second broadcast processing module 320 and the sub-TV receiver 20 are connected via network 10 in separate locations [Distant_Location #1, #2].
[43] A user in [Distant_Location #2] activates RF (UHF) remote control via the RF
(UHF) remocon transmitter 100 in order to watch a broadcast program, the RF (UHF) remocon transmitter 100 transmits a RF (UHF) remote control signal as selected according to the user operation.
[44] The RF (UHF) remocon receiver 200 senses using UHF antenna the RF (UHF) remote control signal transmitted by the RF (UHF) remocon transmitter 100, and outputs the sensed signal to the second broadcast processing controller 325 in the second broadcast processing module 320.
[45] Then, the second broadcast processing controller 325 in the second broadcast processing module 320 sets the broadcast signal receiver 321 to the broadcast channel following the RF (UHF) remote control signal received from the RF (UHF) remocon receiver 200. [46] The second broadcast processing controller 325 further includes functions of, following the RF (UHF) remote control signal, system configuration, menu setup, PVR
(Personal Video Recorder) control, EPG (Electronic Program Guide) control. [47] Using internal modules, the second broadcast processing controller 325 analyses the data of the RF (UHF) remote control signal, controls baseband A/V, and sets the broadcast signal receiver 321 to the broadcast channel via I2C (Inter IC bus) commnand. [48] The MPEG decoder 322, upon receiving a digital broadcast signal for the broadcast channel set in the broadcast signal receiver 321, decodes the received broadcast signal and D/ A converts the decoded signal. [49] The broadcast signal modulator 323, upon receiving a broadcast signal from the
MPEG decoder 322, modulates to a predetermined broadcast frequency and outputs the modulated signal to the amplifier 324. [50] At this time, the broadcast signal modulator 323 may directly output the A/V remote broadcast signal as modulated onto network 10. [51] The A/V remote broadcast signal which is outputted from the broadcast signal modulator 323 may be set to a specific broadcasting channel, or an intermediate frequency for avoiding broadcasting channel frequencies. [52] When the A/V remote broadcast signal is set to an intermediate frequency, as shown in FIG. 3, a modulting unit 330 for re-modulating the intermediate frequency into a specific broadcasting channel frequency may be further included in the sub-TV receiver part of the network 10 in the distant location. [53] The amplifer 324 amplifies the A/V remote broadcast signal which is modulated to a predetermined broadcasting frequency and outputs the amplified signal onto the network 10. [54] Then, the sub-TV receiver 20 receives the A/V remote broadcast signal via network
10, and shows a program corresponding to the A/V remote broadcast signal. [55] The main TV receiver 30 positioned in [Distant_Location #1], following a user operation, selects a channel from broadcast signal received through external transmission medium, receives A/V broadcast signal of the selected channel from the first broadcast processing module 310, and shows a program corresponding to the A/V broadcast signal. [56] FIG. 4 illustrates the multi-out broadcasting receiver system using RF remocon when a plurality of rooms in distant locations is engaged according to present invention, and the detailed description regarding the operation flow for this embodiment is similar to that described above with reference to FIGs. 1 to 3, which lets the repetitive description be omitted in this specification. [57] RF A/V signals in terrestrial TV and set-top box use silent channels (channel free from A/V broadcast signal) out of 51 channels, VHF 3-4 and UHF 21-69, by controlling the broadcast signal modulator (VHF/UHF broadcast signal modulator), which let any interference avoided.
[58] Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
