Real-time transcoding and video distribution in IEEE 802.11b multicast networks

In this paper, we propose a real-time transcoding system to generate contents for mobile networks. Video transcoding is widely used to change storage formats. However, as far as the authors know, it has not been proposed to generate real-time contents. We implement and evaluate an indoor video service that delivers transcoded contents to wireless pocket PCs via IEEE 802.11b multicast. We propose a generic methodology for mobile video planning.
