“…An XML description of the media resource's bitstream syntax can be transformed to reflect the desired adaptation and then be used to generate an adapted version of the bitstream. In our system, BSDL and gBS Schema [46] are used for parsing a bitstream to generate its gBSD description. The bitstream is described based on parcels.…”

One of the major objectives in multimedia research is to provide pervasive access and personalized use of multimedia information. Pervasive access of video data implies the access of cognitive and affective aspects of video content. Personalized use requires the services satisfy individual user's needs on video content. This article attempts to provide a content-on-demand (CoD) video adaptation solution by considering users' preference on cognitive content and affective content for video media in general, sports video and movies in particular. In this article, CoD video adaptation system is developed to support users' decision in selecting their content of interest and adaptively deliver video source by selecting relevant content and dropping frames while considering network conditions. First, video contents are annotated by the description schemes (DSs) provided by MPEG-7 multimedia description schemes (MDSs). Then, to achieve a generic adaptation solution, the adaptation is developed following MPEG-21 Digital Item Adaptation (DIA) framework. We study the MPEG-21 reference software on XML generation and develop our own system for CoD video adaptation in three steps: (1) the content information is parsed from MPEG-7 annotation XML file together with bitstream to generate generic Bitstream Syntax Description (gBSD); (2) Users' preference, network characteristic and adaptation QoS (AQoS) are considered for making adaptation decision; (3) adaptation engine automatically parses adaptation decisions and gBSD to achieve adaptation. Unlike most existing adaptation work, the system adapts the content of interest in the video stream according to users' preference. We implement the above-mentioned MPEG-7 and MPEG-21 standards and provide a generic video adaptation solution. Adaptation based on gBSD avoids complex video computation. Thirty students from various departments were invited to assess the system and their responses have been positive.

“…For bitstreams which do not follow a marker based syntax, specifically if parsing the bitstream would be required to generate a description, the approach using BSDL does not work. For this cases a generic bitstream syntax description (gBSD) is available in MPEG-21 part 7 (see Panis et al [8]) which can be used to directly describe the bitstream.…”

A core concept of universal multimedia access is the use of scalable content. The scalable content should be as flexible as possible to achieve the credo of creating the content once and adapting it to fulfill given requirements. As far as flexibility goes wavelet based codecs are superior. A problem which arises is that the adaptation does not necessarily happen on a device which is aware of the codec which was used in content creation. To rectify this nonawareness, MPEG-21 introduced digital item adaptation in part 7 to abstract the bitstream of a given video. This allows in-network adaptation on nodes which are DIA aware to adapt any video stream as long as a DIA description isgiven. The drawback is that the DIA description must be sent parallel to the original video sequence. In this paper we will look at how a DIA description for a t+2D scalable wavelet codec looks like. We will evaluate the possibilities we have with various description options and we will also look at the overhead generated by the DIA description.
