MPEG-21: goals and achievements

Abstract

MPEG-21is an open standards-based framework for multimedia delivery and consumption. It aims to enable the use of multimedia resources across a wide range of networks and devices. We discuss MPEG-21's parts, achievements, ongoing activities, and opportunities for new technologies. Disciplines Physical Sciences and MathematicsPublication Details

Video in the Web: Technical Challenges and Standardization

“…Insufficient temporal addressing approaches are more or less available in Synchronized Multimedia Integration Language (SMIL), MPEG-7, MPEG-21, 2 and temporal URI. Both SMIL and MPEG-7 require an indirection, though, in that we need to possess the XML description containing the temporal information before the video content can be fetched.…”

Cost-oriented context and content data pair delivery in smart PIN

“…The proposed Smart PIN, a performance and cost-oriented context-aware personal information network, is a novel solution that enables efficient user access to information located on remote devices. Smart PIN handles data pairs that consist of informational context and content, as similarly described by the digital items in MPEG-21 [9]. As a context-aware system, Smart PIN focuses on removing any unnecessary user interaction, while providing performance and cost benefits.…”

Semantic Virtual Environments with Adaptive Multimodal Interfaces

“…Content adaptation implies accessing the same information in different scenarios/contexts, through different interfaces. Efforts aimed at unifying management, delivery, consumption and adaptation of content led to the creation of multimedia frameworks such as MPEG-21 [4], [18]. Content adaptation requires standard representations of content features, functionalities (manipulation/interfacing information).…”
