Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer,, the embodiment of the invention is further elaborated below in conjunction with drawings and Examples.
See also Fig. 1, be the information sharing system structural representation of the embodiment of the invention.Information sharing system of the present invention comprises source end (Source) equipment and destination end (Sink) equipment.Mobile phone is as source end equipment in an embodiment of the present invention, and TV is as destination end equipment.(Digital interface of video and audio, DIVA) interface links to each other by digital audio/video for source end equipment and destination end equipment.In an embodiment of the present invention, source end equipment comprises mobile phone terminal number word audio-video interface, source end interface controller, mobile phone CPU and mobile phone memory, and destination end equipment comprises TV terminal number word audio-video interface, destination end interface controller, TV CPU and video memory.Source end interface controller links to each other with mobile phone terminal number word audio-video interface, mobile phone CPU, mobile phone memory respectively, and the destination end interface controller links to each other with TV terminal number word audio-video interface, TV CPU, video memory respectively.Digital audio/video interface is a kind of new interface that the basis from the UDI interface produces, its physical interface and UDI interface are in full accord, and it is made up of, 1 DDC passage, 1 CEC line, 2 power lines, 1 hot plug holding wire and 1 ground wire 4 differential signals.Digital audio/video interface can the compatible with HDMI interface, also can compatible UDI interface.Digital audio/video interface with the HDMI interface, the UDI interface is different is: UDI interface and HDMI interface all are the one-way transmission data, and digital audio/video interface can bi-directional transfer of data.Digital audio/video interface adopts the reference clock passage passback data in the HDMI interface, can realize half-duplex operation between mobile phone and the TV by the blended data passage in the digital audio/video interface.
See also Fig. 2, be the identification of the information sharing system digital audio/video interface of the embodiment of the invention and the flow chart of foundation.The identification of the information sharing system digital audio/video interface of the embodiment of the invention with set up flow process and may further comprise the steps: step 101: the hot plug signal that detects digital audio/video interface, if the hot plug signal is correct, when being high level, so just thinking has equipment to be connected to the destination end equipment of digital audio/video interface, step 102: the mobile phone end is just determined the parameter of TV display characteristic among the EEPROM by the eeprom memory of DDC line visit TV end, see whether it meets the agreement of digital audio/video interface, if it is suitable then return suitable value, step 103: determine whether it is legal destination end equipment, if legal destination end equipment, connect and set up successfully, be not legal destination end equipment, flow process finishes.
The information sharing system of the embodiment of the invention can realize comprising demonstration, record and functions such as file transfer.See also Fig. 3, the information sharing system of the embodiment of the invention realizes showing, record with the method for file transmitting function and may further comprise the steps: step 301: set up being connected of digital audio/video interface; Step 302: realize Presentation Function; Step 303: realize data-transformation facility; Step 304: judge whether the user selects the video recording operation; Step 305: the user selects video recording operation, and information sharing system can realize the function of record a video and showing on one side, and step 306: the user does not select to record a video and operates, and information sharing system only provides Presentation Function.The concrete implementation of Presentation Function is: after the connection of the digital audio/video interface in the information sharing system is set up, the audio frequency and the video information of mobile phone can be outputed in the digital audio/video interface, at this moment, the effect of television set only provides the demonstration effect, for the source of signal and control from mobile phone.The digital audio/video interface controller of mobile phone is responsible for sending vision signal and audio signal to the TV end, and is responsible for the sign indicating number type that is suitable for the digital audio/video interface transmission is weaved in the encoding video signal operation.Concrete sign indicating number type can be selected the TMDS coding, also can select the ANSI coding.The digital audio/video interface controller of TV is responsible for receiving the sign indicating number type that mobile phone sends, and the sign indicating number type is carried out decode operation, makes it revert to image and digital signal sound, and gives the display module and the audio-frequency module (figure does not show) of TV respectively.At this moment, display message such as the resolution that can show by the TV remote controller adjustment, YC.For the transmission of video data be by three in the digital audio/video interface or 1 differential signal to finishing, the transmission of audio frequency and other control data is then transmitted by the hybrid channel.
See also Fig. 4, realize the flow chart of recording function for the information sharing system of the embodiment of the invention.The specific implementation of recording function may further comprise the steps: step 401: judge to trigger to record whether produce, trigger by the remote controller on the TV and record that TV CPU begins the display module and the destination end interface controller of control of video; Step 402: the bag of the Voice ﹠ Video by digital audio/video, video and audio file that the digital audio/video port is transmitted carry out record; Step 403: original audio frequency, video stream file are stored in the buffer and go, step 404: Voice ﹠ Video file process coding, reduce the size of initial data, make in onesize memory, under the situation that not too influences video quality, can write down longer Voice ﹠ Video information; Step 405: through the audio frequency behind the coding and video information stores in the video memory or outside memory in.The type of memory can be that FLASH also can be SDRAM.
The concrete implementation of file transmitting function is: because " hybrid channel " in the digital audio/video interface is duplex channel, after the digital audio/video interface connection was set up successfully, the user can select the digital audio/video device file pass task mutually by the menu of TV remote controller.At first select equipment, promptly be to select television set or selection mobile phone, after equipment is selected, " hybrid channel " by digital audio/video interface sends order to TV CPU, TV CPU makes response, by software control the content of storing in the mobile phone memory is shown on the video screen, the user can select data are sent in another equipment and go, and the user also can select file deleted or empty operations such as memory.
By the information sharing system of the embodiment of the invention, the picture during the user just can see the mobile phone by TV is by the recreation in the TV object for appreciation mobile phone; Multimedia programming in seeing the mobile phone by TV; Carry out video telephone by TV and other people.And needn't adopt the small screen in the mobile phone and others to carry out video telephone.And can record the video/audio of video telephone in the memory that gets off to store into TV inside or the outside memory and go; The user can also be the phone directory file storage in the SIM card or in the mobile phone internal storage in TV, with standby; The user can also be by the hybrid channel in the digital audio/video interface, and the TV programme that television recording is got off returns to mobile phone; The content of the video telephone of recording is returned to mobile phone; The picture and other the multimedia file of the storage of TV the inside are returned to mobile phone; The phone directory fileinfo is returned to mobile phone.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
