Abstract

In various embodiments, multiple participants (at endpoints) may connect through a video conferencing system. A screen may display other participants in the conference call. For example, multiple participants may be displayed in respective portions of the screen. In some embodiments, each of the participants may use video conferencing systems that support different resolutions. In some embodiments, a transcoder may resolution transcode signals to allow the conference call participants to be displayed on each participant's respective screen at up to the highest possible resolution supported by the respective screen. For example, low resolution video conferencing systems may be displayed on a high definition screen of a high resolution system at the low resolution of the low resolution video conferencing system while another image on the same high definition screen from a different, higher resolution video conferencing system, may be displayed at the higher resolution.
