Handheld Learning - learning with mobile and ubiquitous technologies

PocketVRVS is a new videoconferencing client developed by the VRVS Team for the Pocket PC platform. It supports H.261 video standard and G.711 (?-Law) audio standard. Due to lack of CPU performance the current version of PocketVRVS client doesn't allow sending of live video from Pocket PC camera; however users can send a CIF sized still image stored in JPEG format. For handheld videoconferencing it is only practical to display one video at a time because of the limited screen resolution of a handheld computer. This task is carried out by VRVS reflectors, which send to the PocketVRVS client only the video of current speaker. Minimum requirements are a Pocket PC 2003 with network (wire/wireless) interface and a 400MHz CPU. PocketVRVS works inside networks with NAT (Network Address Translation). First time users will be prompted to enter their name and e-mail for videoconferencing sessions. Later they can change these data using a dialog called "User data..." which is accessible from "Settings" section of Program Menu.
