Optimal adaptation decision-taking for terminal and network quality-of-service

摘要: In order to cater the diversity of terminals and networks, efficient, flexible adaptation multimedia content in delivery path end consumers is required. To this end, it necessary associate with metadata that provides relationship between feasible choices various media characteristics obtained as a function these choices. Furthermore, driven by specification terminal, network, user preference or rights based constraints on are be satisfied process. Using constraint specification, an engine can take appropriate decision for adaptation, efficiently flexibly. MPEG-21 Part 7 entitled Digital Item Adaptation standardizes among other things specifications act interfaces decision-taking component engine. This paper presents concepts behind tools standard, shows universal methods pattern search process information make decisions, some use cases where used.
