Embodiment
Introduce in detail the control system of the tv volume that the utility model provides below in conjunction with accompanying drawing, according to the volume of the environmental volume control television set of the talking state of telephone set and user's communication volume and present position.As shown in Figure 1, telephone set comprises: control unit 40, the incoming telephone signal processing unit 10 that is connected with control unit 40, talking state detecting unit 20, audio collection unit 30.Television set comprises: Image Coding unit 50 and volume processing unit 60.
In addition, described television set also comprises tuner, the video decoding unit that is connected with tuner, audio treatment unit, and the display screen that is connected with video decoding unit and the loud speaker that is connected with audio treatment unit.Said apparatus is not the utility model emphasis, therefore repeat no more.
Incoming telephone signal processing unit 10 is used for the incoming information of caller phone is carried out demodulation process.When incoming call was arranged, switch (not shown) sent modulation signal, and this modulation signal is comprising the information such as calling party's telephone number, date, time, name.After incoming telephone signal processing unit 10 receives described modulation signal, carry out demodulation process.
Wherein, described modulation signal comprises frequency shift keying (FSK, Frequency-shift keying) standard and dual-tone multifrequency (DTMF, Dual Tone Multi-Frequency) standard.The FSK standard in the information that comprises of modulation signal more, except telephone number, also comprise date, time and name etc., its transmission time is between the ring first time and for the second time ring; And the information that modulation signal comprises in the DTMF standard only is telephone number, and the transmission time is before the ring first time.Accordingly, comprise FSK demodulation module 101 and DTMF demodulation module 102 in the incoming telephone signal processing unit 10, to realize that the modulation signal of different systems is carried out demodulation.
Whether whether talking state detecting unit 20 for detection of telephone set network voltage, be switched on and be hung up with the judgement telephone set, and generate the information that the expression telephone set is connected or hung up.
The telephone set standby when namely the extension spring switch of telephone set cuts out, only has ringing circuit and switch (not shown) to connect this moment, and the voltage in the circuit that talking state detecting unit 20 detects is-supply power voltage of 48V.
When having phone to squeeze into, the voltage in the circuit is to be converted to+supply power voltage of 48V, and the alternating current of superpose simultaneously 24V, 25HZ makes its oscillator signal that becomes 72V, 25HZ, drives ringing telephone stations.
Make when picking up a receiver and to hang the spring switch open, when telephone set was connected, voltage drop was+8V ~+18V.
In the present embodiment, the function of incoming telephone signal processing unit 10 and talking state detecting unit 20 can realize by the circuit that comprises the CMX860 chip.CMX860 chip internal structure schematic diagram as shown in Figure 3, comprise the fsk demodulator of realizing FSK demodulation module 101 functions, dtmf signal generator and the dtmf signal receiver of realizing DTMF demodulation module 102 functions, and ringing detector and the offhooking detector of realizing talking state detecting unit 20 functions.
Above-mentioned control command and incoming information view data can be carried out by short-distance wireless communication the transmission of instruction and information, such as by bluetooth, infrared, 2.4G wireless transmission etc., repeat no more.
Wherein, comprise in the control unit 40: parsing module 401, be connected with incoming telephone signal processing unit 10, the incoming information that is used in the future 10 demodulation in Electric signal processing unit carries out dissection process, parse the incoming information view data such as telephone number, date, time, name, transfer to Image Coding unit 50;
Audio frequency control instruction output module 403 is connected with audio identification module 402, is used for according to the difference generation of the volume of described ring back tone or user speech and the background sound volume adjusting instruction to volume adjusting.
Need to prove, when the sound of identifying when audio identification module 402 was ring back tone, the big or small output volume adjusting instruction of audio frequency control instruction output module 403 direct basis ring back tones was to reduce tv volume.After the user connected phone, the difference of the volume of audio frequency control instruction output module 403 User voice and background sound generated the volume adjusting instruction to volume adjusting.
Below in conjunction with Fig. 2 the utility model tv volume control system workflow is described.
Step 101: when telephone set is called, sends the Word messages such as telephone number, date, time, name of caller to television set, and start volume control.
When the telephone set called, the modulation signal that incoming telephone signal processing unit 10 desamplers send carries out demodulation process.Parsing module 401 in the control unit 40 carries out dissection process with the incoming information of above-mentioned demodulation process, parse the incoming information view data such as telephone number, date, time, name, transfer to the Image Coding unit 50 in the television set, being encoded by Image Coding unit 50 is added to after processing in the video image that the TV machine plays.
Talking state detecting unit 20 detects telephone set network voltage, if judge that telephone set is not answered, audio collection unit 30 only collects the ring back tone of telephone set, then judged the size of ring back tone by audio identification module 402, by the size output control command of audio frequency control instruction output module 403 according to ring back tone.The volume processing unit 60 of television set receives above-mentioned control command, regulates tv volume.
Step 102: talking state detecting unit 20 judges whether phone is answered in the setting-up time, if, then carry out next step, otherwise the expression user does not want to answer this phone, and TV is returned to normal broadcast state, and process ends.
When the time of arrive setting, the volume of television set is lowered enough little even be in mute state.If talking state detecting unit 20 detects telephone set and is not answered yet, think that then the user hears phone ringing and is reluctant to receive calls, then audio frequency control instruction output module 403 is exported control commands, and volume processing unit 60 recovers tv volumes to the normal play state, and process ends.
Step 103: audio collection unit 30 gathers environmental background sounds and called subscriber's (be the telephone receiving person) voice, is identified by audio identification module 402, and is compared by audio frequency control instruction output module 403, according to comparative result output control command.
The volume of the background sound that audio identification module 402 identifies and the volume of user speech, compare calculating by audio frequency control instruction output module 403, and according to the difference output volume adjusting control command of this volume, be not less than certain predefined reference difference with the difference of guaranteeing background sound volume and user speech volume, namely guarantee user speech can be significantly and background sound distinguish so that the calling subscriber of phone opposite side can listen to this called subscriber's voice clearly.
Step 104: talking state detecting unit 20 is judged the telephone set on-hook, and by audio frequency control instruction output module 403 output control commands, the control tv volume returns to normally.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model, in a word, all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
