Patients' and therapists' experiences of general change mechanisms during bug-in-the-eye and delayed video-based supervised cognitive-behavioral ther…

2016

Objective This secondary analysis of a randomized controlled trial investigated whether bug-in-the-eye (BITE) supervision (live computer-based supervision during a psychotherapy session) affects the manner in which patients and therapists experience general change mechanisms (GCMs) during cognitive-behavioral therapy (CBT). Method A total of 23 therapists were randomized either to the BITE condition or the control condition (delayed video-based [DVB] supervision). After each session, both patients (BITE: n = 19; DVB: n = 23) and therapists (BITE: n = 11; DVB: n = 12) completed the Helping Alliance Questionnaire (HAQ) and the Bernese Post Session Report (BPSR). The HAQ total score and the 3 …

Personalized multimedia touristic services for hybrid broadcast/broadband mobile receivers

2010

This paper presents the topology of a multimedia tourism service that targets mobile devices equipped with broadband and either multicast or broadcast access capabilities. Multicast / Broadcast access is used to handle the delivery of multimedia data to many simultaneous users in the service area. The solution adopted is based on existing standards for mobile TV services, but introducing features that enable the provision of generic multimedia services on top of mobile hybrid broadband and broadcast networks. Furthermore, this paper shows how to use standardized interfaces originally defined for interactive mobile TV broadcasting to build personalized mobile multimedia services that do not …

Design of an efficient digital down-converter for a SDR-based DVB-S receiver

2007

This paper presents the design of an area-power efficient digital down-converter suitable for broadband communication systems. The DVB-S standard has been used as a design example. It has been shown that by selecting a bandpass sampling to generate only one spectral image, the case in which the relationship between the digital carrier frequency and the sampling frequency is 1/4, not only gives the smallest area but the lowest power consumption.

Audiovisual Representation in Spanish and European Election Debates

2020

The presence of ever more conflicting stances between Europhiles and Eurosceptics has revealed some audiovisual discourses unknown until now. The fragmentation of inconclusive narrative discourse and staged situations with a clear intent to clash all make it necessary to analyse in detail the role given by the audiovisual media to the European process of democratisation. This study addresses the audiovisual discourse in Spanish public television (TVE) with the intention of discovering how the different topics addressed in debates are dealt with in audiovisual production, and whether those topics have benefited from certain decisions by the production team that are subjective a priori. Using…

Filecasting for streaming content delivery in IP datacast over DVB-H systems

2008

In this paper we investigate the potential gain that can be obtained in DVB-H by delivering streaming content as a succession of time-constrained flies using Application Layer - Forward Error Correction (AL-FEC) for improving the reception for mobile terminals. Compared to the conventional approach with link layer MPE-FEC, this technique allows to increase the robustness of the DVB-H transmission not only as a function of the capacity devoted for error repair (FEC overhead), but also as a function of the number of data bursts coded jointly ("file" or, source data block, size). The main drawback of this approach is an increase of the network latency proportional to the source block size, tha…

Valencian Politicians under the spotlight of the À Punt TV network: A study of television coverage of the 2019 regional elections

2020

Despite repeated failures by the former Valencian television network — Canal 9 [Channel 9] — to live up to its public broadcasting duties, the station’s closure in 2013 still came as a shock. The step by the regional government (then run by the Conservative Partido Popular — PP) had a huge public impact, depriving Valencians of their public TV network at a stroke. That is why Valencian society had high hopes when a new public media platform — Punt Mèdia — was launched. Among other things, politicians and broadcasters needed to show that a more even-handed, professional approach could be taken to media reporting. The 2019 Regional Elections were a wonderful opportunity to prove this. On the …

Minimum node weight spanning trees searching algorithm for broadcast transmission in sensor networks

2017

A minimum node weight spanning tree in a weighted, directed graph is a tree whose node with maximum out-weight is minimal among all spanning trees. This type of trees are important because they appear in the solutions of the maximum lifetime broadcasting problem in wireless sensor networks. In a complete graph build of N nodes there are NN-2 spanning trees and to find such trees it is necessary to perform more than O(NN-2) operations. In this paper we propose an algorithm for searching the minimum node weight spanning trees in the graph. In the proposed algorithm, instead of calculating the symbolic determinant of the generalized Laplacian matrix, numerical operations on its exponents are p…

Media for the minorities: Russian language media in Estonia 1990–2012

2013

This article aims to explore the ways in which Estonian public broadcasting tackles one specific media service sphere; how television programmes for language minorities are created in a small country, how economics and European Union media policy have influenced this processes. The article highlights major tensions, namely between Estonian and Russian media outlets, Estonian and Russian speakers within Estonia and the EU and Estonia concerning the role of public service broadcasting (PSB). For research McQuail’s (2010) theoretical framework of media institutions’ influencers – politics, technology and economics – is used. For analyses media regulatory acts and audience surveys are accomplis…
