Embodiment
Basic principle of the present invention is in remote controller, to increase received speech signal and it is carried out the module of handled; Send to WEB-TV through the RF in the remote controller after receiving external voice signal; Through network such as internet voice signal is delivered to target side by WEB-TV then; Be delivered to the receiving terminal (like microphone) of voice signal behind the voice signal that perhaps remote controller reception WEB-TV sends, thereby realize voice transfer through remote controller and WEB-TV.
The system diagram of realization voice transfer of the present invention is as shown in Figure 1, mainly comprises: WEB-TV, two-way remote control and voice signal send and receiving terminal.Two-way remote control is used for the voice signal that voice signal sends and receiving terminal sends is sent to WEB-TV; Perhaps receive and output to voice signal behind the voice signal that WEB-TV sends and send and receiving terminal; WB-TV is sent to target side TV or PC through network such as internet after receiving the voice signal that two-way remote control sends, and perhaps sends to two-way remote control behind the speech data through internet receiving target TV or PC.Wherein:
The theory diagram of two-way remote control of the present invention is as shown in Figure 2:
Two-way remote control can be divided into two transmission channels, and one is input channel, comprises audio input port, the A/D converter that links to each other with audio input port, CPU and the RF that signal is exported; Another is an output channel, comprises RF and the CPU shared with above-mentioned input channel, the D/A converter that links to each other with CPU, and the audio output port that is connected in D/A converter.
The data communication of two-way remote control is two-way, and key value can pass to main frame, and main frame also can pass to remote controller with the state information of its broadcast simultaneously, on the LCD of remote controller panel, shows.
The open spectrum frequency range of 2.4GHz is adopted in the transmission of data communication, does not require directivity.
When utilizing two-way remote control to send voice signal; Audio signal is input to A/D converter through audio input port and carries out the A/D conversion; Audio signal is converted into the CPU that is transfused to two-way remote control after the digital signal and handles; CPU sends speech data packing back through the RF in the remote controller, RF adopts the frequency of 2.4GHz that it is transferred to WEB-TV.
When utilizing the two-way remote control received speech signal; RF receives and to deliver to CPU behind the voice signal that sends from WEB-TV and handle; The voice signal that CPU will handle is sent to D/A converter and carries out the D/A conversion; Export through output port from D/A converter then, the receiving terminal that links to each other with output port (microphone) can receive voice signal.
The theory diagram of WEB-TV of the present invention is as shown in Figure 3; Wherein relevant with the present invention part mainly contains: RF; Be used for receiving the speech data of two-way remote control transmission and send the speech data that WEB-TV outputs to remote controller; Be used for handling the CPU that speech data is handled, and be used for the module that is connected with internet.
Wherein, two-way remote control has both mode of operations, and a kind of is normal remote control mode, and under this pattern, remote controller is carried out the function of common remote controller, like channel search, volume adjusting and picture adjustment etc.; A kind of is audio mode, and under audio mode, remote controller starts the audio transmission function, can pass through the microphone input audio signal, and signal is delivered to CPU with packing data through the A/D conversion, and the RF of process 2.4GHz partly is transferred to WEB-TV; In like manner, the audio signal that sends out of WEB-TV RF, the CPU that can pass through remote controller handles and the D/A conversion outputs to microphone.
The switching of two-way remote control between two kinds of above-mentioned mode of operations can take following mode to realize: through independent button on remote controller or automatically detection whether have microphone to insert to be used for switching working mode.
Below specify flow process through the two-way remote control transmission of speech signals, as shown in Figure 4:
Voice signal is input to remote controller through the microphone of remote controller 1; Through inter-process (sampling of voice signal, quantification, coding, package etc.), to give 2.4GHz wireless transmission means branch to send, the 2.4GHz wireless portion of WEB-TV1 receives after the signal; Carry out processing such as data unpack, decoding; Be sent to the CPU of WEB-TV1 then, CPU again with data packet to can on the internet the Internet, transmitting, arrive the other side's computer or TV with similar functions.Wherein voice transmit in network has had very mature technique realization, just VoIP (IP-based voice technology) now.
2.4GHz radio communication between remote controller and the WEB-TV 1 is that handshake communication is carried out in ID number through equipment is set; Except two the One-to-one communication; Can also realize many-one communication; Realize that promptly a plurality of remote controllers communicate by letter with a main frame WEB-TV, perhaps a remote controller is communicated by letter with a plurality of WEB-TV.
Communication between WEB-TV1 and the WEB-TV2; Because the Internet that communication network uses; Accomplish based on the mode of IP agreement so adopt, the IP bag can adopt broadcasting, multicast, several kinds of modes of clean culture to communicate by letter, so also can support the perhaps communication of many-one, one-to-many one to one.
When voice signal is delivered on the WEB-TV2, WEB-TV2 judges through the IP address of detecting packet whether this packet passes to oneself, if; The CPU of WEB-TV2 will get off Data Receiving, gives the 2.4GHz wireless portion after unpacking, decoding and launches, after this moment, remote controller 2 was received; Determine data address and after own be consistent itself; Will Data Receiving be got off, unpack through the CPU on the remote controller, the D/A of process handles then; Just recovered original analog voice signal, exported through microphone.
WEB-TV2 wherein also can be PC.
In like manner, remote controller 2 can be realized the transmission of voice signal through same flow process.
