Embodiment
Core concept of the present invention provides a kind of device of realizing an one set-top-box to support multi-television sets, after set-top box is passed through multipath decoding with Media Stream, independently export the television receiver unit that is sent to TV set terminal through multichannel, the AV signal that described television receiver unit becomes television set to receive the signal processing that receives, and adopt correlation method to be sent to set-top box the remote signal of television reception.
The invention provides a kind of device of realizing an one set-top-box to support multi-television sets, this device comprises a set-top box, and many television receiver unit that are installed on the TV pusher side, the structural representation of described set-top box as shown in Figure 1, can see that with reference to Fig. 1 described set-top box comprises a primary processor, remote controller signal receiving system, buffer storage, a plurality of decoders etc.
The information of preserving each receiver of remote-control sytem in the described remote controller signal receiving system can receive the multichannel remote signal, sends to the signal of each TV after receiving remote signal according to described information Control.
Its upstream Interface can be the IP network interface, it also can be DVB-T (digital video broadcast terrestrial load mode), DVB-S (digital video broadcast satellite load mode), DVB-C Digital Television interfaces such as (digital video broadcasting copper cable load modes), tuning by multichannel, or the modes such as multiple link of network, can receive the separate Media Stream of multichannel from different program source simultaneously, as the audio/video digital signal, or other services on the network, as the Web web page browsing, recreation, Visual communications or the like.Audio-video frequency media is flowed through behind the upstream Interface by the buffer storage buffer memory, and through primary processor control, the media stream in the buffer storage is carried out audio/video decoding to corresponding decoder, and decoded signal is sent to downstream interface afterwards and shows processing; Display unit is handled and sent to other media datas then by the application program that operates on the set-top box.Its downstream interface comprises the multi-channel video encoder, and the signal behind each road video coding can be delivered on the television set and show, wherein one the tunnel can directly output to nearby television set by the AV cable, and other roads need take corresponding measure to transmit relatively at a distance.
Downstream interface transmits at a distance, and the mode that cooperates with corresponding television receiver unit comprises following three kinds:
First kind of mode as shown in Figure 2, television receiver unit in the setting of TV pusher side comprises television encoder (not shown) and receiver of remote-control sytem, the digital signal that described television encoder is used for sending is carried out video coding, the PAL (Phase Alternate Line) that output television set in coding back can directly receive or the AV of NTSC (NTSC system) or SECAM (forsequential color and store video standard) standard) signal; Described receiver of remote-control sytem comprises an infrared remote receiver, this infrared remote receiver can be installed in the television set front end by lead-in wire, can receive signal from remote controller, and send the signal of described reception to receiver of remote-control sytem and modulate with synthetic, be sent in the remote controller signal receiving system in the set-top box by cable.
This mode operation principle is: the television receiver unit that is sent to the TV pusher side in set-top box by the digital signal behind the decoder decode by the cable of ITU-RBT.601 or ITU-R.BT.656 interface, television encoder in the television receiver unit carries out video coding with described digital signal, export the AV signal that television set can directly receive, be transported to the AV interface of television set.
The cable of wherein said ITU-R BT.601 or ITU-R.BT.656 interface is many to Shielded Twisted Pair, and transmitting ultimate range is 50 meters, enough available in home environment.
The second way as shown in Figure 3, the television receiver unit in that the TV pusher side is provided with comprises frequency demodulator (not shown) and receiver of remote-control sytem, described frequency demodulator is used for demodulation to the received signal and reverts to the AV signal, sends television set AV interface to; Described receiver of remote-control sytem comprises an infrared remote receiver, this infrared remote receiver can be installed in the television set front end by lead-in wire, can receive signal from remote controller, and the sensor signal of described reception modulated, be sent in the remote controller signal receiving system in the set-top box by cable, in described remote controller signal receiving system, revert to the remote signal that set-top box can be discerned.
This mode operation principle is: the AV analog signal that becomes television set to receive through the analog encoding device code earlier by the signal behind the decoder decode in set-top box, because the AV signal can not transmit at a distance, thereby by frequency modulating device described AV analog signal is carried out frequency modulation(FM) again, pass through cable again, as RF (cable TV) coaxial cable, Shielded Twisted Pairs etc. are sent to the receiving element of TV pusher side, frequency demodulator in the receiving element reverts to the AV signal with the signal demodulation, directly is sent to television set AV interface then.
The third mode as shown in Figure 4, television receiver unit in the setting of TV pusher side, comprise receiver of remote-control sytem, described receiver of remote-control sytem is installed in the RF cable end piece, and this receiver of remote-control sytem comprises an infrared remote receiver, and this infrared remote receiver can be installed in the television set front end by lead-in wire, can receive signal from remote controller, at receiver of remote-control sytem signal is modulated, be frequency multiplexed to coaxial cable, in the up remote controller signal receiving system that is sent in the set-top box; In the upstream band, different receivers of remote-control sytem is modulated to different frequencies, and the remote controller signal receiving system of set-top box side obtains from different remote controller signals through demultiplexing.
This mode operation principle is: exported through television encoder by the signal behind the decoder decode in set-top box, pass through synthesizer then, multi-channel TV signals is modulated to different frequent points, and by the output of RF radio frequency, transmit cable and generally adopt cable tv coax, this signal is delivered directly to the RF receiving port at the TV pusher side, and television set is by being tuned to the signal that the frequency points corresponding receiving set up box sends.
In sum, the present invention has realized utilizing set-top box to drive multiple TV set, and makes multi-channel television independence received signal, realizes easyly, has reduced the cost of one family multiple TV set configuration machine top box, and the while also brings convenience for the maintenance management of operator.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
