چکیده

Video coding is used under the hood of a lot of multimedia applications such as video conferencing, digital storage media, television broadcasting, and internet streaming. However, offering universal access to video content is far from trivial when taking into account the diversity of current networks and terminals. In this paper, we will discuss how MPEG-21-based technology can be combined with a recently standardized video compression scheme. This can be seen as a first step in order to create a framework that allows optimal usage of video data under constraining cir-

A performance evaluation of MPEG-21 BSDL in the context of H.264/AVC

H.264/AVC is a new specification for digital video coding that aims at a deployment in a lot of multimedia applications, such as video conferencing, digital television broadcasting, and internet streaming. This is for instance reflected by the design goals of the standard, which are about the provision of an efficient compression scheme and a network-friendly representation of the compressed da...

Using Placeholder Slices and MPEG-21 BSDL for ROI Extraction in H.264/AVC FMO-Encoded Bitstreams

The concept of Regions of Interest (ROIs) within a video sequence is useful for many application scenarios. This paper concentrates on the exploitation of ROI coding within the H.264/AVC specification by making use of Flexible Macroblock Ordering. It shows how ROIs can be coded in an H.264/AVC compliant bitstream and how the MPEG-21 BSDL framework can be used for the extraction of the ROIs. The...

Real-Time BSD-Driven Adaptation Along the Temporal Axis of H.264/AVC Bitstreams

MPEG-21 BSDL offers a solution for exposing the structure of a binary media resource as an XML description, and for the generation of a tailored media resource using a transformed XML description. The main contribution of this paper is the introduction of a real-time work flow for the XML-driven adaptation of H.264/AVC bitstreams in the temporal domain. This real-time approach, which is in line...

Multi-frame motion-compensated video compression for the digital set-top box

Motion-compensated prediction based on multiple previous or future frames can enhance the compression efficiency of video coding. Multi-frame prediction can be applied as an extension to P-Pictures, but also to B-Pictures in the form of multi-hypothesis prediction. We review recent advances, several of which have been embraced by the ITU-T Rec. H.263 and the emerging JVT/H.26L standard, jointly...
