Today's mobile and wireless users access multimedia content from different types of networks and terminals. Content analysis plays a critical role in developing effective solutions in meeting unique resource constraints and user preferences in such usage environments. Specifically, content analysis is central to automatic discovery of syntactic-level summaries and generation of concise semantic-level summaries. Content analysis also provides a promising direction for finding optimal adaptation methods under various resource-utility constraints. This paper presents brief overviews of such emerging, fruitful areas and promising research directions.
