Integrated Soft Media/Channel Image Communications. Consumer Opportunities in QoS Control

In this paper we propose exploitation of a great amount of redundancy usually communicated at the user level. A well- known soft channel decoding approach used in telecommunications is extended to a ?soft media decoding? concept and an integrated media/channel soft decoding scheme has been proposed. Simulation results show the efficiency of the proposed approach for typical image communications over different channels. The main advantage of the proposed integrated media/channel soft decoding scheme is the possibility of repetition (or replication) decoding when different source encoding methods are used. Such methods include different quantization methods, different JPEG qualities or even different coding schemes such as DPCM, JPEG, DWT etc..
