In some embodiments, a videoconferencing system may support using high definition images (e.g., 1280×720 pixels) for high definition displays. The videoconferencing system comprises a plurality of participant locations that may participate in the videoconference. Each participant location may comprise videoconferencing equipment, such as at least one camera, microphone(s), a display, one or more speakers, and a videoconferencing codec. The camera may be a high definition camera operable to acquire or capture images having a high resolution compatible with HDTV. In one embodiment, the videoconferencing equipment comprises a H.264 encoder and is operable to encode the video stream of high definition images using H.264 encoding techniques. In one embodiment the network may be 1.544 MB or less (e.g., T1 or less). In another embodiment, the network is 2.048 MB or less.
