Abstract

The advent of widespread mobile communications together with the continuous development of image communication markets led to the idea of offering mobile image communications, particularly mobile videotelephony. Since very low bitrate video coding is still a quite unexplored subject, a large research effort is being put into the study of the possible solutions. For the moment two main approaches related to the compatibility or not with the CCITT H.261 hybrid coding scheme are foreseen. This paper proposes some experiments related to the CCITT H.261 compatible solution in order to look for its limits, namely when typical mobile videotelephone sequences are used.
