Abstract

A communication terminal for video conferencing with remote participants, including a receiver receiving audio and video signals from a plurality of the remote participants, and a display. In one form, a comparator compares the audio signals and a controller controls the display to display the video images extracted from the video signals based on the comparison of the received audio signals. In another form, the display has a height greater than its width and operates in a portrait mode in a default condition, and a controller controls the display to display the extracted video images in a landscape mode when the receiver receives the video signals from a plurality of the remote participants. In yet another form, a processor associates the received audio signals with the video signal received from the same remote participant, with the display displaying one of the video images on the right and another video image on the left, where an audio output sends the audio signal associated with the one video signal to a right speaker and sends the audio signal associated with the other video signal to a left speaker.

22. The mobile terminal of claim 21, wherein said controller controls said display to display only said one video image.

23. The mobile terminal of claim 21, wherein said controller controls said display to display video images other than said one video image in areas smaller than the area in which said one video image is displayed.

24. The mobile terminal of claim 20, wherein said controller controls said display to highlight said one video image by displaying a distinctive border around said one video image.

25. The mobile terminal of claim 20, wherein said controller controls said display to highlight said one video signal by displaying alphanumeric identification regarding said one remote participant.

26. The mobile terminal of claim 20, wherein said controller controls said display to highlight said one video image by displaying video images other than said one video image using a color scheme different than the color scheme used to display said one video image.

27. The mobile terminal of claim 15, wherein:

said receiver receives a video data signal; and

said controller controls said display to highlight one video image and a video data image extracted from said video data signal based on said comparison of said received audio signals from said remote participants by said comparator.
