- FIG. 4 shows a schematic structural diagram of an application server of the present invention. Preferred embodiment of the invention
- the system for privacy protection in a video call includes a video gateway, a 3G terminal, and a media server.
- the media server and the video gateway are under the control of the application server, according to user attributes. Decide which video to play.
- the signing user first uses the pre-set contract video clip in the system to replace the real video image captured by the mobile phone camera, and can dynamically switch between the real video and the substitute video during the call. .
- the method extends the business functions of the videophone service and meets the personalized video requirements of the user.
- the media server needs to play the video clip stored by the user on the media server or the user selected video clip to the peer to replace the video at the time.
- the user who wants to protect his or her privacy needs to be a subscriber of the video replacement, and the main called party can be a subscriber of the video replacement.
- the video-substitute sign-up user first transmits to the opposite end a certain video clip to replace his own real video. If you want to give the opposite end your own real video, then you can press the indicator button to cut to yourself. The real video is given to the opposite end.
- the video gateway needs to separate the sending and receiving address information (IP+PORT) on the Internet Protocol (IP) side, that is, the video sending is separated from the video receiving address information, and the audio sending and audio receiving address information are separated;
- IP Internet Protocol
- a stream address information of one nature has both the function of transmitting and receiving the stream; and the remote IP of the audio and video address information of the same 324m channel may be different, for example: the far of the video address information of a 324m channel
- the end may be ipl + portl, and the far end of the audio address information may be ip2 + port2.
- the 3G terminal A can be the first terminal, and the 3G terminal B can also be the first terminal.
- the following 3G terminal A is the first terminal as an example for description.
- the implementation steps are as follows:
- the application server When the 3G terminal A dials the 3G terminal B, the application server first determines whether A and B are the subscribers of the video replacement.
- the Session Initiation Protocol (SIP) control message is sent to notify the video gateway to send the real video to the other party: that is, the 324m channel connected to A (hereinafter referred to as 324m-).

- the signing user wants to change or cancel the substitute video during the call, he can switch between the real video and the substitute video by pressing the specified button. If the application server receives an indication to cancel the replacement video in the call and cuts to the real video, then the local and remote address information corresponding to the subscription user needs to be modified. At this time, the address information of the transmitted video of the 324m-A channel and the address information of the received video of the 324m-B channel are mutually remote address information; the media server channel of the substitute video playing A is closed.
- the application server first determines whether A and B are subscribers of the video replacement.

- the remote address information of the transmitted audio and video address information of the A channel corresponds to the received audio and video address information of the 324m channel (hereinafter referred to as 324m-B channel) connected to B, and the received audio and video address information of the 324m_A channel and the 324m_B channel Send audio and video address information corresponds.
- both parties are real videos to the opposite party.
- the application server finds that A is a video replacement subscription user and B is also a subscription user, then When the B answers the call, the application server notifies the media server and the video gateway and B through the SIP control message to perform the next step.
- the video gateway A After receiving the SIP control message of the application server, the video gateway A sets the remote address (IP+PORT) of the video sending address information of the 324m_A channel to be invalid.
- the media server After receiving the SIP control message of the application server, the media server parses the video file that A wants to play to B and the address information that is played to the remote end:
- the remote address information of the video file sent by the media server is the received video of the 324m_B channel. Address information.
