After set-top box obtains the required power supply signal of its operate as normal can be provided, be not to enter operating state immediately, be provided with a bootstrapping module in set-top box inside, after the set-top box energized, at first will carry out himself necessary bootstrapping operation to set-top box by the bootstrapping module.In the bootstrapping process, the bootstrapping module will be carried out Power-On Self-Test, and whether the operating state that detects its inner all elements normal, and to operations such as all elements activate, with guarantee and the starter motor top box after operate as normal.And after bootstrapping is finished,, will send incoming notification signal to television set by the plug-in interface if the bootstrapping module does not detect the anomaly of set-top box.
Step 203, the set-top box state monitoring module of television set generate set-top box and connect signal behind the incoming notification signal that receives the set-top box transmission;
Particularly, in the plug-in interface that television set is connected with set-top box, be provided with the pin that is used for the incoming notification signal that set-top box sends is transferred to television set, in the set-top box side, this pin is connected with the bootstrapping module of set-top box, at the TV pusher side, this pin is connected with the set-top box state monitoring module of television set.After the set-top box bootstrapping is finished, incoming notification signal transfers in the set-top box state monitoring module of television set by this pin, and the set-top box state monitoring module of television set is monitored notification signal from set-top box in the mode that triggers all the time, therefore after one receives the incoming notification signal of set-top box, to generate corresponding set-top box immediately and connect signal, and send to the demonstration switching controls module of television set, there is set-top box to insert at this moment and this set-top box enters in the operating state with the demonstration switching controls module of informing television set.
Step 204, if receive first switching command that the user sends, the demonstration switching controls module of television set connects the signal and first switching command according to set-top box, sends first display control signal to television signal receiver module;
The demonstration switching controls module of television set is used to control the concrete play mode of television set, for example be to play digital television program by set-top box, still need not the participation of set-top box, directly play analog television program by television set, thereby the television signal receiver module of control television set sends to set-top box with the original tv signal that receives by the plug-in interface, signal after will handling again after the signal processing of set-top box sends to first display module of television set inside, perhaps directly the original tv signal is sent to second display control module of television set inside, and specifically select which kind of broadcast mode to decide by remote controller by TV user.
For TV user, after being connected with set-top box on the television set, it can be selected when any one comes TV reception in the following dual mode voluntarily by TV remote controller: it can select to watch digital television program by set-top box, it also can select need not the participation of set-top box, only watch analog television program by television set. according to user's different choice, television set will be realized the different flow processs that displays the play. when the user selects by the set-top box TV reception, to send the control corresponding instruction to television set by remote controller, in the present embodiment, be called first switching command. if the demonstration switching controls module of television set receives this first switching command, and when this moment, signal that the set-top box state monitoring module sends was also for set-top box connection signal, promptly show this moment not only set-top box entered normal operating state, and the pattern of televising of user's selection simultaneously is also for playing the pattern of digital television program by set-top box, therefore show that the switching controls module will send first display control signal to the television signal receiver module that receives the original tv signal, so that television signal receiver module is passed through plug-in interface transmitter top box with the original tv signal that receives, with parsing and the processing of carrying out corresponding signal.
Step 205, the television signal receiver module of television set will send to set-top box by the plug-in interface via the original tv signal that the TV signal interface receives according to first display control signal;
Particularly, the television signal receiver module of television set is after receiving the original tv signal from the TV signal input interface, immediately it is not sent, but according to showing that the control command decision that the switching controls module sends sends it to second display control module of self or sends to set-top box by the plug-in interface.When user's selection is watched digital television program by set-top box, the television signal receiver module of television set receives first display control signal that shows that the switching controls module sends, so it sends to set-top box by the plug-in interface with the original tv signal that receives, and carries out the processing of conversion of signals for set-top box.In the present embodiment, television set is divided into two kinds of situations by original tv signal and the concrete receive mode that the TV signal input interface receives:
First kind of situation, the TV signal that television set receives by the TV signal input interface is the original figure TV signal, the TV signal input interface that receive this original figure TV signal this moment is specially an Ethernet interface, and this television signal receiver module is specially an Ethernet switching chip.The original figure TV signal that television set receives from Ethernet interface must be by playing at television set after the signal processing of set-top box, be that television set does not have the function of resolving this original figure TV signal, therefore, Ethernet switching chip is after receiving the set-top box display control signal that shows the transmission of switching controls module, directly the original figure TV signal is redirected the transmitter top box by the plug-in interface, and and with its second display control module that does not send to self to carry out decode operation, the Audio Processing chip of looking in the set-top box will be to carrying out the demultiplexing of TV signal, the conversion operations of demodulation and digital and analogue signals is converted to this original figure TV signal the simulation video/audio signal that can be received and play by television set;
Second kind of situation, the TV signal that television set receives by the TV signal input interface is a radio television signal, the TV signal input interface that receive this radio television signal this moment is specially a coaxial cable interface, and this television signal receiver module is specially a splitter chip.Particularly, radio television signal be through radio frequency processing later digital television signal and the mixed signal of anolog TV signals, and the signal of telecommunication that carries TV signal this moment is an analog form.Splitter chip is after receiving this radio television signal, it is not carried out substantial treatment, but convert thereof into the same signal of two-way, after receiving the set-top box display control signal that shows the transmission of switching controls module, road signal is wherein sent to set-top box by the plug-in interface, in the present embodiment, claim that this road signal is a first via radio television signal.After the looking the Audio Processing master chip and receive the first via radio television signal that television set sends of set-top box, at first it is carried out demodulation process, extract digital television signal wherein, and the digital television signal that extracts carried out the processing of demultiplexing, demodulation and the conversion of digital-to-analogue video/audio signal, this processing procedure is the same with existing set-top box processes mode.
Also need to prove in addition, in above-mentioned steps 204, the instruction that the user sends also might be second switching command, this second switching command refers to that the user selects directly to use television set to watch analog television program. at this moment, the demonstration switching controls module of television set is according to this second switching command, need not to judge whether set-top box normally is connected to television set, just can send second display control signal to television signal receiver module, so that television signal receiver module sends to second display control module with the original tv signal that receives. in above-mentioned two kinds of situations, when the original tv signal is the original figure TV signal, second display control module of television set does not possess and can resolve and control the function that it shows on display screen to it, therefore the Ethernet switching chip of this moment is in such cases, even receive the television set display control signal, the original figure TV signal that receives can not sent to second display control module yet.
And in second kind of situation, the original tv signal is a radio television signal, at this moment, when television signal receiver module is splitter chip, splitter chip carries out shunt to radio television signal to be handled, and the first via radio television signal, also obtains the second tunnel radio television signal simultaneously after obtaining along separate routes, this the second tunnel radio television signal all is consistent with the content of first via radio television signal and original radio frequency TV signal, and indifference.Because second radio television signal is the mixed signal of digital television signal and anolog TV signals, second display control module of television set can partly be handled and displays the play anolog TV signals wherein.Therefore, this moment is if the Port Multiplier chip receives second display control signal that shows that the switching controls module sends, just the second tunnel radio television signal can be sent to second display control module of self, second display control module will extract the anolog TV signals part from the second tunnel radio television signal, and it is carried out decoding processing and controls it and play on display screen.
Also need to prove in addition, no matter be which kind of above-mentioned situation, all must be integrated with a class pin that the original tv signal is sent to set-top box from television set in the plug-in interface of set-top box and television set, at the TV pusher side, this pin connects the television signal receiver module of television set, and in the set-top box side, this pin junctor top box look the Audio Processing master chip, by such pin, when set-top box was connected with television set, the original tv signal that television set could be received sent to set-top box and carries out Signal Processing.
