The kindest cut: Enhancing the user experience of mobile tv through adequate zooming
No full textThe growing market of Mobile TV requires automated adaptation of standard TV footage to small size displays. Especially extreme long shots (XLS) depicting distant objects can spoil the user experience, e.g. in soccer content. Automated zooming schemes can improve the visual experience if the resulting footage meets user expectations in terms of the visual detail and quality but does not omit valuable context information. Current zooming schemes are ignorant of beneficial zoom ranges for a given target size when applied to standard definition TV footage. In two experiments 84 participants were able to switch between original and zoom enhanced soccer footage at three sizes - from 320x240 (QVGA) down to 176x144 (QCIF). Eye tracking and subjective ratings showed that zoom factors between 1.14 and 1.33 were preferred for all sizes. Interviews revealed that a zoom factor of 1.6 was too high for QVGA content due to low perceived video quality, but beneficial for QCIF size. The optimal zoom depended on the target display size. We include a function to compute the optimal zoom for XLS depending on the target device size. It can be applied in automatic content adaptation schemes and should stimulate further research on the requirements of different shot types in video coding
Ich-Erzählen im Medium des Frühdrucks. Narrative und diskursive Strukturen in gedruckten deutschsprachigen Reimerzählungen um 1500 (Hans Folz, Sebastian Brant, Hans Sachs).
No full textMy paper presents three German poems from the late 15th/early 16th cen-tury that formally stand in the tradition of couple rhymed allegorical first-person narratives and thematically deal with the political conditions of their time. The three different authors represent two variants of a certain type of author belonging to the artisan class (Hans Folz, Hans Sachs in Nuremberg) or to the academically educated, bilingual (Latin/German) upper class (Sebastian Brant in Strasbourg) of the urban bourgeois culture. In both cases, they opened up early to the new medium of book printing. Consequently, the para-texts with which all three texts produced directly for print are equipped take on important functions within the new printing medium and the new practise of distance communication that develops from it, aiming above all at the staging of the respective authorship. The three selected case studies high-light the different literary and communicative strategies developed by each author under these auspices. What all three texts have in common, however, is a more or less sophisticated play with the two different discourse levels of the (fictional) narra-tor ego and the (real) author ego. Such a game is at the same time anchored in essen-tial aspects within the socio-cultural environment of the authors and the respective specific literary culture. Thus, in the case of Hans Folz, as in the case of his successor Hans Sachs, the effort to adapt the handed-down medieval traditions and rhetoric models to the new conditions of vernacular communication visibly predominates. Differently, the concept of authorship claimed by Sebastian Brant is characterised by the effort to harmonise the function of the poet as orator and prophet, derived from the humanist tradition, with the instructional tasks fundamental to vernacular poet
Theticity
No full textThe subject matter of this chapter is the semantic, syntactic and discoursepragmatic background as well as the cross-linguistic behavior of types of utterance exemplified by the following English sentences […]: (1) My NECK hurts. […] (2) The PHONE's ringing. [...] Sentences such as […] are usually held to stand in opposition to sentences with a topical subject. The difference is said to be formally marked, for example, by VS order vs. topical SV order (as in Albanian po bie telefoni 'the PHONE is ringing' vs. telefoni po bie 'the PHONE is RINGING'), or by accent on the subject only vs. accent on both the subject and the verb (as in the English translations). The term theticity will be used in the following to label the specific phenomenological domain to which the sentences in (1) and (2) belong. It has long been commonplace that these and similar expressions occur at particular points in the discourse where "a new situation is presented as a whole". We will try to depict and classify the various discourse situations in which these expressions have been found in the different languages, and we will try to trace out areas of cross-linguistic comparability. Finally, we will raise the question whether or not there is a common denominator which would justify a unified treatment of all these expressions in functional/semantic terms
Dante in Nürnberg. Ein Rezeptionsbeispiel aus dem 16. Jahrhundert.
No full textIl contributo analizza la poesia "Historia: Dantes, der poet von Florentz" del poeta di Norimberga Hans Sachs (1494-1569) e il suo modello letterario, una facezia di Poggio Bracciolini. A questo proposito viene ricostruito la complessa tradizione delle Facezie di Poggio all'interno dell'Esopus tedesco di Heinrich STeinhöwel e la sua successiva continuazione da parte dell'Umanista di Straßburgo Sebastian Brant
A User-Focused Reference Model for Wireless Systems Beyond 3G
No full textThis whitepaper describes a proposal from Working Group 1, the Human Perspective of the Wireless World, for a user-focused reference model for systems beyond 3G. The general structure of the proposed model involves two "planes": the Value Plane and the Capability Plane. The characteristics of these planes are discussed in detail and an example application of the model to a specific scenario for the wireless world is provided
