Description

Karar "OK" picture-in-picture device

The utility model relates to a kind of Karaoke picture-in-picture that the singer is inserted the Karaoke background frame.

Along with the develop rapidly of science and technology, people's culture life is also more and more abundant, and a kind of people can please oneself, much more more and more Karaoke facility happy certainly, self-expression also comes across in commerce, public place of entertainment and people's the family.At present, popular Karaoke facility can not satisfy the singer and see the performance of enjoying oneself when the lyrics and background frame are sung, singer's on-the-spot demonstration picture can't insert the Karaoke background frame, thereby also just can not enjoy existing singer and perform, the excellent picture of Karaoke background frame is arranged again, it can not be recorded simultaneously.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of Karaoke picture-in-picture, it is simple in structure, with low cost, singer's performance can be inserted in the Karaoke background frame, the remote-controlled own position in picture of singer, size and with the exchange of background frame etc.

The purpose of this utility model can reach by following measure:

A kind of Karaoke picture-in-picture device comprises remote control transmitter (1), and its special character is: its output of receiver of remote-control sytem (2) that receives remote control transmitter (1) signal connects instruction decoder (3), and the output of instruction decoder (3) connects PIP module (4).

Remote control transmitter 1 of the present utility model can comprise remote-control transmitting integrated circuit (IC2), and its output connects the emitter that triode (T) infrarede emitting diode (D1) is connected to triode (T); Described receiver of remote-control sytem 2 comprises remote control receiving integrate circuit (IC3), and the output of infrared receiving diode (D2) is connected to its input 1 pin.

Instruction decoder of the present utility model can be made of decoding integrated circuit (IC4).

The accompanying drawing drawing is described as follows:

Fig. 1 is a theory diagram of the present utility model

Fig. 2 is circuit theory diagrams of the present utility model

The connection layout of Fig. 3 when to be that the utility model is actual use.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Referring to Fig. 1, remote control transmitter 1 is provided with function key, when the user presses a certain function key, remote control transmitter 1 to its encode, pulse modulation, drive its infrarede emitting diode then and send the corresponding instruction information code.Receiver of remote-control sytem 2 will be put in advance by the signal that remote control transmitter 1 sends, demodulation by filter, shaping are handled, input instruction decoder 3 is decoded after being reduced into the command information sign indicating number, decoded signal is sent in the PIP module 4, finish every function by it by command request, as: little picture inserts big picture, and big or small picture exchanges, and little picture moves to four jiaos, occur four little pictures simultaneously, little picture amplifies, dwindles.

Fig. 2 is the circuit theory diagrams of the utility model embodiment.The 220V alternating current is exported the 9V alternating voltage after transformer B transformation, it is again through the bridge rectifier D rectification, and through capacitor C 1, C2 filtering, output+5V direct voltage behind three-terminal regulator block IC1 voltage stabilizing and capacitor filtering is for the utility model provides relevant power supply.Remote control transmitter 1 mainly is made of remote-control transmitting integrated circuit (IC) 2, triode T and infrarede emitting diode D1, when the user presses a certain function key, integrated circuit (IC) 2 converts the key bit code to the function command sign indicating number, amplifies excitation luminescence diode D1 by triode T and send infrared signal after amplitude modulation.Receiver of remote-control sytem 2 mainly is made of remote control receiving integrate circuit IC3 and infrared receiving diode D2, when D2 receives the infrared signal that luminous tube D1 sends, produce and represent of the 1 pin input of this voltage of signals by IC3, through preposition amplification, amplitude limit amplifies, bandpass filtering, detection, restore of the 7 pin output of command information sign indicating number after the shaping by IC3, delivering to instruction decoder 3 is 14 pin of decoding integrated circuit IC4, after IC4 identification decoding, with control signal corresponding respectively by 4 pin of IC4,6 pin, 7 pin, 9 pin, 10 pin, 11 pin are delivered to PIP module 4 corresponding each function pin.4 pairs of PIP modules from the two-path video signal of 3 pin, the input of 4 pin after A/D conversion, separated in synchronization and demodulation process, again one tunnel synchronizing signal separation is wherein selected and Filtering Processing, send into dynamic memor, synchronizing signal separation is read from dynamic memor by row, a timing sequential of key frame then, after the D/A conversion, according to the position that sprite is selected that the signal of key frame and sprite is synthetic, become composite video signal after tristimulus signals after synthetic are encoded, give the video inputs of television set by 1 pin of PIP module.In above-mentioned signal processing, the control signal according to PIP module 7 pin, 8 pin, 9 pin, 10 pin, 11 pin are received respectively can realize following function: single picture/four pictures; The little picture of little picture/do not have is arranged; Little picture position; Movable/static; Little picture amplifies/dwindles.

Winding diagram when Fig. 3 uses for the utility model.Singer 5 is when singing, take microphone 6 on the other hand, take remote control transmitter 1 on the other hand, video camera 7 is converted into the vision signal input 2 that vision signal is input to the utility model 10 with singer 5 image frame, video recorder 9 with Kara OK function vision signal of will playing Karaoka is delivered to the vision signal input 1 of the utility model 10, after the utility model 10 is handled, background music that comes out from video recorder 9 and singer 5 song mixed audio signal are delivered to audio frequency input or other stereo set of television set 8, like this, singer 5 is when sing karaoke, just can be by the remote control transmitter 1 in the hand, oneself performance playback image on the screen of television set 8, and is carried out the screen picture adjustment at any time.The Karaoke image of band picture-in-picture when record machine machine 11 can be used for recording on-the-spot the performance.The similar module that PIP module of the present utility model also can adopt Hitachi, Ltd, NEC Corporation, ITT Corp. to produce is replaced.Integrated package among the utility model embodiment all is selected from the CUA060 system, and what three-terminal regulator block IC1 adopted is 7805; That remote-control transmitting integrated circuit (IC) 2 adopts is D6121G001; That remote control receiving integrate circuit IC3 adopts is CX20106A; That decoding integrated circuit IC4 adopts is M9081.

The utility model compared with prior art has following advantage:

1, the image of singer's on-the-spot demonstration can be inserted at that time the Karaoke background frame, thereby on video screen, can see simultaneously small one and large one two pictures.

2, singer's little picture can be arbitrarily mobile at the big picture of Karaoke background four jiaos, and little picture can occur four simultaneously on big picture, and large and small picture also can be changed mutually, and little picture is scalable to be dwindled.

3, the utility model is simple in structure, and volume is little, and cost is low, dependable performance, and peripheral cell is few, and it is all convenient to make, use.
