Method for voice grouping processing in a kind of TV conference system comprises the following steps:
Step 1, multimedia control unit are made into a meeting with all set of terminal that participate in a conference;
Step 2, is as required divided into groups to the terminal in the meeting;
Step 3, the acoustic processing pattern of each group is set;
Step 4, hold a meeting, in the group the multimedia control unit adds each terminal according to the configuration in the step 2 under;
Step 5, be unit, sound handled according to the tupe of setting in the step 3 with the group.
Group technology in the above-mentioned steps 2 is: choose the terminal that needs and form a group from meeting, meeting is divided into several groups, a terminal can be participated in different groups, has at least a terminal inequality in per two groups; The group that all terminals of dividing into groups to be left is formed an acquiescence.
Adopt the method for the invention, compared with prior art, improved sound processing method in traditional MPTY field, earlier meeting is divided into groups, be that unit carries out audio mixing to sound or broadcasting is handled then with the group, dumb sound and quiet control to terminal also are to be unit with the group, and its effect is only effective in this group, do not influence the state of other groups of this terminal-joined.So just can realize the panel discussion function of having a meeting and secret talk function easily, the flexibility that has improved system has increased the range of application of system.

Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the flow chart of the method that proposes of the present invention, and as shown in Figure 1, the method for voice grouping processing in the TV conference system that the present invention proposes comprises the following steps: that step 1, multimedia control unit are made into a meeting with all set of terminal that participate in a conference.Step 2, as required, terminal in the meeting is divided into groups, and group technology is: choose the terminal that needs and form a group from meeting, meeting is divided into several groups, a terminal can be participated in different groups, has at least a terminal inequality in per two groups; The group that all terminals of dividing into groups to be left is formed an acquiescence.Step 3, the acoustic processing pattern of each group is set, as broadcast mode or audio mixing mode.Step 4, hold a meeting, in the group under each terminal is added according to the configuration in the step 2; Step 5, be unit, sound handled according to the tupe of setting in the step 3 with the group.Corresponding step 3 if this group is arranged to broadcast mode, is then passed to the sound of broadcast terminal other member terminal of this group, is broadcasted terminal and then selects the sound of listening this member terminal of group arbitrarily; If this group is arranged to the audio mixing mode, whether the someone makes a speech then to detect each member terminal in this group in real time, with the mixing that superposes of the audio code stream of detected speech terminal, mixed data send to each member in this group, its code stream has been participated in stack if certain member terminal is detected speech, then deducts the code stream composition of this terminal oneself before mixed code stream is sent to this terminal.
Further, in conference process, the present invention can also be unit with the group, and the single terminal in organizing is carried out dumb sound control and quiet control.Dumb sound control: if select dumb sound, then the output code flow clear " 0 " with this terminal sends to the acoustic processing module, otherwise gives the acoustic processing module with the true output code flow of this terminal; Quiet control:, then the output of acoustic processing module clear " 0 " is sent to this terminal, otherwise the true output of acoustic processing module is sent to this terminal if select quietly.
In conference process, the present invention can also add dynamically the member of group, delete or revise: if a terminal is dropped by the wayside meeting, then withdraw from the group of all its participation simultaneously; If a terminal adds meeting midway, then add the group that it need be participated in, if it does not belong to any one group, then it is added the group of acquiescence.
Further specify implementation process of the present invention below in conjunction with Fig. 2 and Fig. 3 and specific embodiment.In one embodiment of the invention:
