An optimized 11.264-based video conferencing software for mobile devices

Abstract

Mobile phones and related gadgets in networks are on the spot to deliver sufficient performance for rich multimedia applications and communication. In this report we introduce a video conferencing software, which seamlessly integrates mobile with stationary users into fully distributed multi-party conversations. Innovations related to this work are twofold. At first we report on a highly optimized realisation of a H.264 codec and our implementation experiences of the video conference \em software on a consumer mobile. Within the tight bounds of real-time requirements on mobiles, the coding software outperforms compatible H.264 realizations. At second we present an integrated peer-to-peer group communication solution, which scales well for medium-size conferences and accounts for the heterogeneous nature of mobile and stationary participants.
