Abstract

There are many reasons for developing video services over networks without Quality of Service (QoS) guarantees. One reason is that the cost of a non-QoS connection will be substantially cheaper for the user. Another reason is that although networks of the future will provide the option for a QoS connection, today's networks have no such provisions. This position paper presents a novel approach to the problem by acknowledging that a successful solution must contain both a networking and an image processing perspective. The proposed approach should have better visual quality and utilize network resources more fully then current techniques.
