| Abstract: | There are two new trends in today's computer technology that are attracting more and more attention. One is multimedia service,especially the video service. The other is mobile wireless computing. The former can be implemented efficiently on the traditional wired network, such as the accession of multimedia information, real-time broadcast. But due to the limitation of the wireless environment,the latter hasn't been able to support the video transport efficiently. Obviously,the combination of these two technologies,video service over wireless network,may be a killer application and in turn advances both of them. This paper summarizes the challenges of this field and introduces some possible solutions. |
