The notion of subband sampling. A proposition for the construction of extra high value bi-directional communication system

Next generation multimedia communication should give a better sense of presence, as well as picture and voice quality. On the other hand, transporting data streams with highest quality losslessly over a network is not an easy task. Data quantity is huge and difficult to handle. The real-time constraint of interactive communication only permits us a very short delay with no `resend´ policy. Yet, network resources are limited, and (lossless) real-time compression is still needed to meet bandwidth constraints. This paper describes the outline of constructing a communication system with extra high quality data streams, focused on subband sampling, a reviewed method for intraframe coding
