In this paper, attention is paid to the automatic generation of XML-based descriptions containing information about the high-level structure of binary multimedia resources. These structural metadata can then be transformed in order to reflect a desired adaptation of a multime-dia resource, and can subsequently be used to create a tailored version of the(More)
In order to efficiently deal with the heterogeneity in the current and future multimedia ecosystem, it is necessary that content can be adapted in a format-agnostic manner. A first step toward a solution, able to fulfill the just mentioned requirement, is to rely on a scalable video codec and to describe the high-level structure of the resulting bitstreams(More)
Recommended by Dimitrios Tzovaras Video scalability is a recent video coding technology that allows content providers to offer multiple quality versions from a single encoded video file in order to target different kinds of end-user devices and networks. One form of scalability utilizes the region-of-interest concept, that is, the possibility to mark(More)
Recently, the H.264/AVC standard has been extended to incorporate Scalable Video Coding (SVC). SVC offers the advantage of scalable (layered) coding, but has the disadvantage of a highly increased computational complexity at the encoder side when dealing with spatial scalability. To restrict the increase in required processing power, fast mode decision(More)
— The heterogeneity in the current and future multi-media environment requires an elegant adaptation framework for the production and consumption of different kinds of multimedia content. Such an architecture is preferably based on the usage of scalable bitstreams and a format-agnostic content adaptation engine. To obtain fully embedded scalable bitstreams,(More)
