This document describes an architecture for the transport of IP Datagrams over ISO MPEG-2 Transport Streams (TS). The MPEG-2 TS has been widely accepted not only for providing digital TV services but also as a subnetwork technology for building IP networks. Examples of systems using MPEG-2 include the Digital Video Broadcast (DVB) and Advanced Television Systems Committee (ATSC) Standards for D...

In this article, we investigate efficient transmission of Object-based MPEG-4 video over IP networks with QoS management capabilities. MPEG-4 Audio Visual Objects (AVOs) are classified based on application-level QoS criteria and AVOs semantic descriptors according to MPEG-7 framework. MPEG-4 AVOs requiring same QoS performance from the network are automatically classified and multiplexed within...

This chapter covers key technologies in wideband audio coding including auditory masking, perceptual coding, frequency domain coding, and dynamic bit allocation. The MPEG standardization work is then described. MPEG algorithms have found a wide range of communications-based and storage-based applications. For example, European digital audio broadcast (DAB) makes use of MPEG-1. It will then be s...

We designed and implemented a digital library system that supports content-based retrieval of multimedia objects based on MPEG-7 and XQuery. MPEG-7, a metadata standard for multimedia objects, can describe various features such as color histograms of images and content descriptors. As such, a multimedia digital library system built with MPEG-7 metadata can provide content-based search for multi...

The MPEG-7 is the dominant standard for multimedia content description; thus, the audiovisual Digital Library contents should be described in terms of MPEG-7. Since there exists a huge amount of audiovisual content in the cultural heritage domain, it is expected that several cultural heritage objects, as well as entities related with them (i.e. people, places, events etc.), have been described ...

The use of domain knowledge in semantic audiovisual content descriptions enhances the functionality and effectiveness of the multimedia applications. However, the dominant standard for audiovisual content description today (MPEG-7) does not describe a formal mechanism for the systematic integration of domain knowledge and reasoning capabilities in the MPEG-7 descriptions. The specification of a...

MPEG-4 is an important international standard with wide applicability. This paper focuses on MPEG-4’s main profile, video, whose approach allows more efficiency in coding and more flexibility in managing heterogeneous media objects than previous MPEG standards. This study presents evidence to support the assertion that for non-SIMD architectures and computational models, most memory-system opti...

The transition to digital in the TV broadcasting industry is already gradually being performed while the complete digital switchover seems now possible to be accomplished within the near future. This article describes and analyses this phenomenon and the role of MPEG-21 may play in it. MPEG-21 is the ISO/IEC standard currently under development in MPEG (ISO/IEC JTC1/SC29/WG11). Unlike preceding...

1 and MPEG-7 2 standards provide new ways for authoring, transporting, access-ing, retrieving, and interacting with multimedia content. MPEG-4 is the first standard that supports interactive and complex audio–visual presentations , while MPEG-7 standardizes the description of various types of multimedia content. Complex authoring tools are required to create the powerful reusable and interactiv...

For the past two years the Moving Pictures Expert Group (MPEG), a working group of ISO/IEC, have been developing MPEG-7 [1], the "Multimedia Content Description Interface", a standard for describing multimedia content. The goal of this standard is to develop a rich set of standardized tools to enable both humans and machines to generate and understand audiovisual descriptions which can be used ...
