Fig. 1B is a schematic diagram of a lecturer viewing both the first type of multimedia information of the lecturer and the second type of multimedia information of the lecturer during the network teaching process.
In the embodiment of the invention, in order to improve the quality of network teaching and avoid the interference of the lecturer to the lecturer, the first type of multimedia information comprises video information and audio information, and the second type of multimedia information comprises the video information but not the audio information, namely, the lecturer can see the pictures of the lecturer and can hear the sound of the lecturer, but can only see the pictures of other lecturers and can not hear the sound of other lecturers, so the interference of the lecturer to the lecturer can be effectively avoided.
The above description is for improving the quality of network teaching and avoiding the interference of the lecturer to the lecturer, and the obtained second-class multimedia information of the lecturer only includes video information and does not include audio information. In the embodiment of the present invention, the purpose of improving the network quality may also be achieved by adopting a manner that, for example, the second type of multimedia information may include video information or audio information, but only the video information is played and the audio information is not played during playing, that is, both the first type of multimedia information and the second type of multimedia information include video information and audio information;
when the second type of multimedia information is played, the following method can be adopted:
and only the video information included in the second type of multimedia information is played.
That is to say, in order to improve the quality of the network teaching and avoid the interference of the lecturer to the lecturer, although the acquired second type of multimedia information of the lecturer includes both the video information and the audio information, only the video information is played instead of the audio information during the playing, so that the effect of improving the quality of the network teaching can be achieved.
In practical applications, there may be speakers in the lecturers, and in order to enable the lecturers to more clearly view the lecturers who speak, the playing interface of the lecturer who speaks may be adjusted to be larger than the playing interfaces of other lecturers who do not speak, therefore, in an embodiment of the present invention, if the lecturers include one or more lecturers who speak in a video mode, the method further includes the following operations:
and adjusting the playing interface corresponding to the one or more lessees speaking in the video mode to be larger than the playing interfaces corresponding to other lessees.
