Abstract

Transmultiplexation changes the parallel transmission into a serial transmission. Integer-to-integer filters ensure the perfect reconstruction. The paper presents a suitable serialization method which improves the robustness of images transmitted by a trans-multiplexer system. The solution is based on blocks of sizes adequate to separation filter orders, used in detransmultiplexation. The proposed method results directly from the detransmultiplexation algorithm. An example of a four-channel transmultiplexer system, equipped with integer filters, is presented and analyzed to illustrate the suggested method. A simple and effective filter design method is also presented.
