LG Electronics indicated yesterday it has developed a mobile phone that allows users to engage in multi-user video conferencing.
Called “push-to-view”, or PTV, its an extension of PTT (push-to-talk), which uses a walkie-talkie-like approach. LG plans to demonstrate their WCDMA-based PTV technology at the 3GSM World Congress in a few days.
| Details are scarce, but LG’s PTV approach is probably based on the IP Multimedia Subsystem (IMS) standard, which defines a generic architecture for offering Voice over IP (VoIP) and multimedia services. |
