Description

TECHNICAL FIELD The present invention relates to the field of videophone technology of a mobile communication terminal, and particularly to a videophone capable of protecting portrait rights of an unfamiliar video call and a method for protecting the same . BACKGROUND OF THE INVENTION With the start of operation of China's 3G network, 3G videophones have gradually entered the lives of ordinary Chinese consumers. People can use the videophone function of videophone to conveniently communicate voice and images, avoiding ordinary voice calls. I only heard the flaws of his voice. By using the video image transmitted by the videophone, the user can see the avatar expression of the other party, understand the current emotion of the other party from the facial expression, and judge the psychological activity, which is beneficial to the communication between the two parties. The mobile terminal videophone can be implemented by the CS (circuit switch) circuit domain using the 3G-324M protocol stack of the 3GPP Partnership Project (3G Partnership Project). The 3G-324M protocol stack is a system solution for mobile multimedia phones, including H.223 protocol, H.245 protocol, wireless modem (modem) protocol and audio and video codec module. The H.223 protocol is mainly used for multiplexing and demultiplexing voice, video, and data streams. The multiplexing process is to reuse the audio, video code stream and protocol stack control data output from the local codec module. The entry is multiplexed from the multiple logical channels into a bit stream to be transmitted, and sent to the physical channel for transmission. The demultiplexing process is to decompose the peer bit stream received from the physical channel according to the multiplexing table, and the 4 bar video, audio stream and control data are separated into different logical channels, and then the local system performs the next processing. .

The H.245 protocol is mainly used for the negotiation process of the two parties' videophones, and controls the entire protocol stack session process. The H.245 protocol is required for control during session establishment, session in progress, and session termination. The H.245 protocol provides end-to-end signaling, enabling capability exchange, master-slave decisions, command and indication signaling, and opening and describing the contents of logical channels.

The 3G-324M wireless modem works in synchronous full-duplex mode, following the V.34 and V.8 standards. The output of H.223 should be output directly to the synchronous data pump of V.34. If the terminal is connected to the V.34 modem via the medium, it should be connected via the V.250 protocol. The audio and video codec module is mainly used for the encoding and decoding process of voice and video, from the local 4 Nie image head

The video and audio data obtained by (Camera) and the microphone (Microphone, referred to as MIC) are encoded by the encoder into a binary stream and sent to the multiplexing module for processing; the audio and video streams decomposed from the demultiplexing module are passed through the decoder. The original audio and video data decoded into the original can be sent directly to the speaker (Speaker) and liquid crystal display (LCD) for playback. 1 is a schematic diagram of a conventional mobile videophone session. As shown in FIG. 1, when a first mobile terminal calls a second mobile terminal, the first mobile terminal first sends a mobile service center (Mobile Service Center, referred to as The MSC sends a video call message, and after receiving the call message, the MSC sends a paging message to the second mobile terminal, and the wireless protocol stack processes the paging message, and initiates a request to establish a Circuit Switch Data (CSD) link. . After receiving the MSC link setup success message, the wireless protocol stack notifies the videophone application to start ringing, prompting the user to answer the videophone. When the user chooses to answer the videophone, the 3G-324M protocol stack is started. The protocol stack performs the videophone service negotiation through the H.245 message, and the peer responds to the negotiation result, confirms the logical channel, codec and other parameter messages. Established successfully. Set the parameters according to the negotiation result, configure the camera, microphone and speaker device, open the codec and video, audio logic channel, multiplexer multiplexing and demultiplexing the code stream data, and enter the video call state. After the call ends, the user presses the on-hook button (the first mobile terminal and the second mobile terminal can actively press the on-hook button to be parsed by the 3G-324M protocol stack), stop and destroy the 3G-324M protocol stack, and notify the modem through the AT command interface. Hang up, remove the CSD link, and the videophone process ends. As can be seen from the above process, there is a problem in the existing videophone, that is, for all videophone incoming calls, after the user connects the call, the image of the local end is immediately transmitted to the opposite end, so that The user can immediately capture the user's image through the shutter function, and the user's avatar may be randomly captured, edited, or even distributed by some malicious people, causing the user's portrait right to be easily invaded, causing great trouble to the user. In the existing patents for videophone portrait rights protection, it is basically used on the local end.

The method of processing the original video image captured by the camera, for example, Chinese Patent Application No. CN00805189, uses an exaggerated deformation method on the original video image, so that the avatar video received by the opposite end is different from the user's portrait, thereby protecting the user's Portrait right. The Chinese patent application No. CN200610143714 transmits the copyright information in the original video image, and the opposite end displays the received video data through the multimedia copyright object, thereby protecting the user's portrait right. Although the above method can play the role of portrait protection, the implementation technology is relatively complicated, and it needs to add complex image processing functions, especially for systems that use software codec, which may take up a lot of CPU time. And memory space, reducing the efficiency of the system. SUMMARY OF THE INVENTION The present invention has been made in view of the problems in the prior art that the technology of videophone portrait protection is complicated and occupies a lot of resources.

Step S202: After the CSD link is successfully established, the user videophone wireless layer notifies the application layer, the user videophone starts ringing, prompting the user to answer the videophone; Step S203, the user answers the videophone After the protocol stack is started, the local end and the peer end start to exchange 3G-324M signaling, and negotiate the parameters and information about the terminal capability, the multiplexing table, the codec type, and the media device of the two parties through the H.245 message; S204, according to the negotiation result of H.245, select the mobile level of mutual interaction, configuration The multiplexed entry, the format of the audio and video codec, and the like; Step S205, the user visually reads the video source attribute in the associated phone book, and determines which video source the video call belongs to, that is, the file video source or the Camera video source Step S206, if the video source of the video call selects the file video source, the video information in the file is started to be read, and the read data is sent to the multiplexer together with the audio data and the control data, and the video call starts. When the user does not see the portrait of the user, only the video file played by the user can be seen. If the video source selected by the video call is a Camera video, step S212 is performed; Step S207, it is determined whether to switch the video, that is, the user passes the voice or The peer video determines whether the peer is willing to see the portrait video of the peer; in step S208, if the user is willing to switch to the Camera video source, the switching operation is performed, so that the opposite user sees his or her portrait video, if the user does not perform the switching. Operation proceeds to step S210; in step S209, the user and the opposite party are finished talking, and the on-hook button is pressed to stop and release The protocol stack resource, the wireless link is removed, and the videophone call ends; in step S210, the peer does not see the user's portrait video, that is, after the user confirms by voice or the opposite video, the opposite end is a stranger, and is unwilling to the opposite end. Seeing the portrait video of the user, the switching operation is not performed; Step S211, the user presses the on-hook key, stops and releases the protocol stack resource, removes the wireless link, and the videophone call ends; step S212, the video source selected by the video call is Camera Video, capture video stream and audio data from Camera, control data and send it to the multiplexer, the videophone call starts, the peer can see the user's portrait; Step S213, the user and the peer end the call, the local end Or press the end button on the opposite end to stop and release the protocol stack resources, remove the wireless link, and the videophone call ends. 3 is a schematic diagram of an interface of a default video source option setting of a videophone according to the present invention. As shown in FIG. 3, the user can set a video source attribute for each group or each phone number in the phone book, which can be set to Camera video or File video, if you select a file video, you must also set the corresponding file. The file can be taken by the videophone, or it can be obtained from the Camera photo, or it can be downloaded by the user through the network or other means. 4 is a schematic diagram of an interface for switching a video source in a videophone video call according to the present invention. As shown in FIG. 4, the user can switch the video source according to the user's will at any time during the video call, and switch from the Camera video source to When the file video source is used, the default file determined in advance can be used, or the new file can be re-selected instead of playing; the user can also switch from the file video source to the Camera video source.

Application scenario of the embodiment: Step 1: The user sets the video source attribute related to the phone book on his own video phone in advance, for example, setting the number of the video source attribute of the group of friends to the Camera video source, and not wanting to let the other party To see the number of your portrait is set to the file video source, select a suitable video file as an alternative video source; for unfamiliar number calls, the default is to connect to a user-specified file video source, the user must specify one for the default connection in advance. File video source. Step 2: The user receives a video call, and the videophone automatically determines the video source attribute of the calling number. If the number is a strange number, the video source is the file video source, and the user sees the playing after the user connects the phone. Video file, the user's portrait is not visible. After confirming the voice or the peer video, if the user is found to be the person who knows or is willing to see the portrait of the other party, you can choose to switch the video source and switch the video source to the video stream captured by Camera. You can see the portrait of the user. If the user confirms by voice or the opposite video, finds that the other party is a stranger or does not want the other party to see his or her portrait, you can not switch the video source, and the opposite end can not see the user's portrait, which can be effective. Prevents the problem of being caught, edited, or even scattered by the other party when connecting to a strange video call. In step 2, when the user receives a video call from the friend, the videophone determines that the video source attribute of the calling number is a Camera video source, and directly transmits the video stream captured by Camera, and the peer friend will see the user's portrait. If the user is temporarily inconvenient during the call to let the peer friend see his or her avatar, the user can choose to switch to the file video source. At this time, the video call will select the user's default video file to play to the peer friend, which is convenient for the user. Handling video call problems in different scenarios; Step 3: After the video call is completed, the user or the peer user presses the on-hook button, the videophone stops the protocol stack and releases the resources, removes the wireless link, and ends the call. It should be noted that the user can of course set all of his own numbers as file video sources. When a video call comes in, when the user connects to the videophone, the other party sees the file video. In this case, the user can Decide whether to switch to the Camera video source. In summary, according to a videophone and a method for protecting the right of the portrait according to the embodiment of the present invention, different video sources are associated according to different groups of the phone book, and the video call request can be judged and processed during the call, thereby The protection of the user's portrait right does not need to add complicated video image processing, which reduces the difficulty of implementing the existing videophone, achieves the protection of the portrait number of the strange number, and avoids the portrait of the end user from being browsed by strangers. The purpose of snapping and distributing. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. It should be noted that any modifications, equivalents, or substitutions made within the spirit and principles of the present invention will be apparent to those skilled in the art. Improvements and the like should be included in the scope of the present invention.
