Description of drawings
Fig. 1 is the functional block diagram of universal communication system of the present invention.
Embodiment
With reference to the accompanying drawings, describe the embodiment of the invention in detail.
Fig. 1 shows the functional block diagram of universal communication system of the present invention.As shown in Figure 1, universal communication system of the present invention mainly comprises:
Capturing images unit 101; Universal communication system of the present invention major function is that video telephone, fax or image transmit as mentioned above.Therefore, capturing images unit 101 is requisite parts, and it can be the device that image unit, camera, digital camera etc. can obtain vision signal or picture signal, is used to capture various videos or picture signal, these signals can be dynamic, also can be static;
Video processing unit 102, this video processing unit 102 directly links to each other with capturing images unit 101, be used to receive the image or the vision signal of capturing images unit 101, it is handled accordingly, these processing comprise: mould/number conversion is (if 101 employings of capturing images unit is digital device, then do not need this processing), preliminary treatment, pre-amplify etc., export digitized video or picture signal;
Sound acquisition unit 103, corresponding with capturing images unit 101, this sound acquisition unit 103 is mainly used in the acquisition voice signal, comprises music, voice, background sound etc., and operable parts comprise: microphone;
Sound processing unit 104 directly links to each other with sound acquisition unit 102, is used to receive the voice signal of sound acquisition unit 103, and it is handled accordingly, and these processing comprise: mould/number conversion, preliminary treatment, pre-amplification etc., export digitized voice signal;
Mixed cell 105 links to each other with sound processing unit 104 with video processing unit 102, and digital view or the picture signal and the digital audio signal of receiver, video processing unit 102 and sound processing unit 104 outputs carry out numeral to this phase signals and mix;
Signal compression unit 106 links to each other with mixed cell 105, receives the mixed signal of mixed cell 105 outputs, and this mixed signal is compressed, and the method for compression can adopt conventional compression method.The effect of this signal compression unit 106 is to reduce data volume, so that transmit fast and efficiently; Certainly, if according to actual needs, perhaps do not consider transmission quantity, this compression unit 106 also is omissible, and for example for real-time Transmission, compression may cause the delay of transmission, if bandwidth is enough, can image and sound mix signal is not compressed, directly transmission is to improve the real-time of transmission.Use for non real-time, can image and sound mix signal be stored in (back will specifically describe) in the memory earlier by compression, then, transmission again;
CPU 107, this unit 107 is core components of universal communication system of the present invention, coordinates and control the running of each parts;
Operating unit 108, this operating unit 108 is the interface units with user or user, be used to receive user or user's input, input can comprise data or all kinds of instruction, each parts are controlled by CPU 107, for example, when the user instructs by operating unit 108 input shootings, 107 of CPU are sent control signal to capturing images unit 101, started working in capturing images unit 101 (camera), pickup image, simultaneously, CPU 107 receives this picture signal; In specific embodiment, operating unit 108 can adopt keyboard as operating unit;
Voice unit (VU) 110, this voice unit (VU) 110 also links to each other with CPU 107, be used to play the voice signal of CPU 107 outputs, voice signal can comprise sound acquisition unit 103 acquisition sound, also can play the voice signal that comes by the telephone wire transmission;
Modulatedemodulate unit 111, CPU 107 is after the video/audio mixed signal that receives mixed cell 105 (if not using signal compression unit) or signal compression unit 106 transmission, this signal is handled, to be suitable for offering modem module 111, modem module 111 is modulated this video/audio mixed signal, offer telephone unit 112 then, outwards transmit by telephone wire, except outwards transmitting by telephone wire, can also pass through the Internet, perhaps mode such as broadband networks is outwards transmitted.In addition, if necessary, CPU 107 also can provide picture signal to display unit 109, provides voice signal to voice unit (VU) 110, with synchronous display image and playing sound;
Modulator-demodulator 111 except modulation signal with the outside transmission, can also receive telephone unit 112 from the modulation signal that telephone wire (or the Internet, broadband networks etc.) transmission comes, this modulation signal is carried out demodulation, offer CPU 107.According to above-mentioned application of the present invention, received modulation signal is generally picture signal or voice signal, perhaps the mixed signal of image and sound.CPU 107 according to circumstances, picture signal is separated with voice signal, offering voice unit (VU) 110 and elementary area 109 then respectively plays and shows, this working method can realize user both sides' video call, if insert a plurality of users (for example user more than three), then can realize teleconference;
Memory cell 113 links to each other with described CPU 107, is used to store various types of signal or data; When capturing images unit 101 and sound acquisition unit 103 acquisition images or sound, the mixed signal of mixed cell 105 or compression unit 106 outputs can store in the memory cell 113 earlier by CPU 107, then, after capturing images unit 101 and sound acquisition unit 103 quit work, from memory cell 113, take out this mixed signal file by CPU 107 again, outwards transmit by modem module 111 and telephone unit 112, so just can realize the multimedia Email of similar Email.Here so-called multimedia is meant that the signal of transmission has comprised image and sound.The other user is after receiving this mixed signal file, can be earlier this mixed signal file storage in memory cell 113, then, after finishing receiving, CPU 107 reads this mixed signal file again, plays and shows by voice unit (VU) 110 and display unit 109.The advantage of this transmission means is that owing to employing non real-time mode is transmitted, and data can be compressed earlier, therefore, can significantly reduce the transmission time of data; Even another advantage is that the other side does not exist, also can transmit and receive, realized the function of voice and image Email.
Here alleged memory cell 113 can adopt RAM at specific embodiment, also can adopt hard disk drive or floppy disk, perhaps these parts is combined.If adopted software driver in this device, then except the image and voice signal of the capturing images unit 101 that can transmit this device and 103 acquisitions of sound acquisition unit, can also transmit ready-made image or audio files, even can transmit the file of other form or content, the for example file of text formatting, perhaps an executable file.When transmitting the file of text formatting, this communicator has played the effect of traditional E mail.
Describe specific embodiments of the invention above in detail, but be to be understood that, above-mentioned specific descriptions only are used for just with understanding principle of the present invention, be not to limit the scope of the present invention, the general personnel in present technique field are under the situation that does not break away from the spirit and scope of the present invention, can make various variations and distortion to the present invention, for example, operating unit 108 can also adopt mouse; Also voice unit (VU) 110 and display unit 109 can be made one; Perhaps in whole device, omit sound acquisition unit 103 and sound processing unit 104; Perhaps set up an interface unit in addition, be used for being connected etc. with miscellaneous equipment.
