This paper describes the design and implementation of the aggregation framework for UPnP/DLNA home network. The proposed aggregation service aggregates contents list from UPnP media servers in a home network and present them in a single contents list. The aggregation framework is designed to use as minimum bandwidth as possible in home network and to provide backward compatibility to UPnP media server...
The highly sensitive nanowire-based Schottky-gate nanosensors for detecting UV, bio-molecules, and gas sensing were demonstrated. The operating mechanism of the Schottky-gate nanosensors is totally distinct from the conventional Ohmic contacted nanosensors. The Schottky–gated device (SGD) has a few merits in comparison to the conventional Ohmic contacted device (OCD). First, it needs no bio-probe...
This paper presents a framework to ensure application interoperability for heterogeneous IPTV client devices with different capabilities by providing application scalability. To support device independent application in IPTV service environment, we suggest a new XML schema (named Scalable Application Markup Language: SAML) based on MPEG-21 DIDL (Digital Item Declaration Language).
In an audiovisual scene consisting of high capacity multimedia objects, when a scene change, which an object is inserted, deleted, or replaced in real time by user interaction, is required, the object priority order compositor for an multimedia player according to the present invention performs rendering of objects based on priority order of objects. The compositor searches priority order of objects,...
We present strategies to improve low open-circuit voltage (Voc) for ZnO-poly(3-hexylthiophene) (P3HT) photovoltaic devices, which are typically ≤0.4 V, but vary among different reports. One factor affecting Voc variability is the ZnO bandgap (Eg), which depends on detailed processing conditions. By decreasing the pyrolysis temperature of sol-gel ZnO films, we increased the ZnO Eg by 0.14 eV and Voc...
With the further increasing popularity of multimedia devices, such as laptop computers, personal digital assistants (PDAs), and smart phones, there is a rapidly growing demand for efficient real-time playback and transmission of large amounts of multimedia data, but most users' connections are not fast enough to download large chunks of multimedia data. Moreover, when switching to another device while...
