Abstract

With the introduction of a multitude of video and multimedia services in the context of broadband communication networks, compatibility between various different data compression systems is becoming increasingly important. Significant research efforts have been recently directed towards so-called hierarchical coding schemes that provide compatibility by splitting the source signal into several hierarchical layers. Compatibility is achieved in this way since a receiver selects and decodes only those layers which are relevant for its (fixed resolution) display monitor. In this paper we introduce and investigate two hierarchical spatio-temporal subband decompositions; the so-called ’full’ and ’reduced temporal hierarchy’ decompositions. The former supports progressive-scan video signals only while the latter is capable of handling interlaced signals as well. The better frequency discrimination of the ’full temporal hierarchy' decomposition is expected to lead to higher coding performances for the interlaced signals but has a higher complexity.
