This paper focuses on concurrent real-time multimedia group communication in wireless environment and proposes a video conferencing system to support multiparty streaming video communication on mobile devices. The proposed solution extends session initiation protocol (SIP) to support multicast session negotiation and uses mobile multicast in IP layer for media data distribution. Since wireless network...
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...
This paper presents a channel-aware video streaming method that does not only adjust dynamically the target bit rate according to the channel condition but also minimize the error propagation at handoff. The proposed method performs adaptive bit rate allocation (ABA) by using the carrier to interference and noise ratio (CINR) to reduce the packet loss ratio (PLR) without wasting the channel resource...
