Abstract

A display allocation method is disclosed herein. The display allocation method is applied to a display in a conference meeting and comprises the following steps: allocating a first, a second and a third image block on the display, in which sizes of the first and the second image block are larger than size of the third image block; detecting an effective sound of a first candidate video corresponding to the third image block to identify whether the first candidate video is effective; setting one of the first and the second image block as a primary image block, and setting another one of the first and the second image block as a secondary image block, in which the secondary image block includes a secondary video; and allocating the first candidate video and the secondary video to the secondary and the third image block respectively if the first candidate video is effective.

First claim

What is claimed is:

1. A display allocation method applied to a display in a conference meeting, comprising:
allocating a first image block, a second image block and a third image block on the display, wherein sizes of the first image block and the second image block are larger than size of the third image block;
detecting an effective sound of a first candidate video corresponding to the third image block to identify whether the first candidate video is effective;
setting one of the first image block and the second image block as a primary image block, and setting another one of the first image block and the second image block as a secondary image block, in which the secondary image block includes a secondary video; and
allocating the first candidate video to the secondary image block and allocating the secondary video to the third image block if the first candidate video is effective.

2. The display allocation method of claim 1 , wherein the step of identifying whether the first candidate video is effective further comprises:
identifying whether the effective sound lasts longer than a first specific time length.

3. The display allocation method of claim 1 , wherein when the display allocation method operates in a first mode, the display allocation method further comprises:
setting one of the first image block and the second image block as the primary image block according to a user input.

4. The display allocation method of claim 1 , wherein the secondary video is the earliest video connected to the conference meeting other than a primary video of the primary image block.

5. The display allocation method of claim 1 , when the display allocation method operates in a second mode, further comprising:
identifying which of a first video of the first image block and a second video of the second image block has a primary effective sound, wherein the primary effective sound is the closest to a time point when the first candidate video is identified to be effective; and
identifying whether the primary effective sound lasts more than a second specific time length, if the primary effective sound lasts more than the second specific time length, setting the image block corresponding to the primary effective sound as the primary image block, and setting the other image block as the secondary image block.

6. The display allocation method of claim 5 , wherein the step of setting the primary image block and the secondary image block further comprises:
counting time lengths of effective sounds corresponding to the first video and the second video respectively within a specific time length before the time point if the primary effective sound does lasts no longer than the second specific time length;
setting the image block corresponding to the effective sound with the longer time length as the primary image block, and setting the other image block as the second primary image block.

7. The display allocation method of claim 1 , further comprising:
setting a fourth image block on the display, wherein size of the fourth image block is the same as the size of the third image block;
detecting a second candidate video of the fourth image block so as to identify whether the second candidate video includes the effective sound; and
maintaining the first candidate video in the third image block and maintaining the second candidate video in the fourth image block if the first candidate video of the third image block and the second candidate video of the fourth image block both have the effective sound.

8. The display allocation method of claim 1 , wherein a frequency range of the effective sound is from 100 hz to 800 hz.

9. A video conference system, comprising:
a display, the display comprising a first image block, a second image block and a third image block, wherein sizes of the first image block and the second image block are both greater than size of the third image block; and
a processing unit, comprising:
a detection module, configured to detect a first candidate video of the third image block so as to identify whether the first candidate video has an effective sound;
a set module, configured to set one of the first image block and the second image block as a primary image block and to set another one of the first image block and the second image block as a secondary image block, wherein the secondary image block includes a secondary video; and
an allocation module, configured to allocate the first candidate video to the secondary image block and to allocate the secondary video to the third image block when the first candidate video has the effective sound.

10. The video conference system of claim 9 , wherein the detection module is further configured to identify whether the effective sound lasts longer than a first specific time length.

11. The video conference system of claim 9 , wherein the processing unit further comprises a reception module, wherein the reception module is configured to receive a selection command from a user, and the set module is further configured to set one of the first image block and the second image block as the primary image block when the selection command corresponds to selecting a first mode.

12. The video conference system of claim 9 , wherein the secondary video is the earliest video connected to the conference meeting other than a primary video of the primary image block.

13. The video conference system of claim 9 , wherein the processing unit further comprises a reception module, the reception module is configured to receive a selection command of a user, and the set module is further configured to identify which of a first video of the first image block and a second video of the second image block has a primary effective sound when the selection command corresponds to selecting a second mode, wherein the primary effective sound is the closest from a time point when the first candidate video is identified to be effective; and the set module is further configured to identify whether the primary effective sound lasts more than a second specific time length, and the set module set the image block corresponding to the primary effective sound as the primary image block and set the other image block as the secondary image block if the primary effective sound lasts more than the second specific time length.

14. The video conference system of claim 13 , wherein the set module counts time lengths of effective sounds corresponding to the first video and the second video respectively within a third specific time length before the time point if the primary effective sound does lasts no longer than the second specific time length, and the set module sets the image block corresponding to the effective sound with a longer time length as the primary image block, and setting the other image block as the second primary image block.

15. The video conference system of claim 9 , wherein the display further comprises a fourth image block, the detection module further detects a second candidate video of the fourth image block so as to identify whether the second candidate video includes the effective sound, and the set module is configured to maintain the first candidate video in the third image block and to maintain the second candidate video in the fourth image block if the first candidate video of the third image block and the second candidate video of the fourth image block both have the effective sounds.

16. The video conference system of claim 9 , wherein a frequency range of the effective sound is from 100 hz to 800 hz.
