Embodiment Construction

[0018] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0019] This embodiment will describe videophone signal scrambling from the perspectives of the calling user and the called user respectively:

[0020] Fig. 1 is a flow chart of calling process of videophone signal scrambling in the present invention. Specific steps are as follows:

[0021] Step 101: the calling user selects a video call;

[0022] Step 102: Before starting the video call, the terminal prompts the user whether to scramble the local data, where the calling user chooses to scramble the local data;

[0023] If the user chooses not to scramble the local data, it will be processed according to the flow of ordinary video calls.

[0024] Step 103: the calling user dials the called number to make a video call;

[0025] Step 104: The other party answers and conducts a videophone call;

[0026] Step 105: The calling terminal ...

Abstract

The method comprises: user end scrambles the local data obtained from media device, and sends the scrambled new data packet to the opposite end to display. Said scrambling process comprises: local end gets the local data from media device; setting a portion of said data as invalid value; combining the invalid data portion with the valid data portion to form a new data packet, and making the invalid portion of data evenly distributed in the new packet.

Description

technical field [0001] The invention relates to a videophone service of a terminal in the communication field, in particular to a method for scrambling a local signal of the videophone service. Background technique [0002] Mobile videophone is a point-to-point communication service that uses video and voice at the same time. It realizes two-way real-time communication of video and audio between two mobile terminals, a mobile terminal and a fixed video phone or PC, that is, the two parties in the call In the process, they can see each other's scenes. [0003] In the existing videophone service, while the mobile videophone is talking, both the calling party and the called party must send and receive multimedia video and audio signals at the same time. If the local video signal is not provided, it is necessary to provide a substitute picture or substitute video to replace the local video signal. [0004] In special cases, the user needs to provide the real-time video and aud...
