Quality of experience in skype video calls

Skype is one of the well-known applications that has guided the evolution of real-time video streaming and has become one of the most used software in everyday life. It provides VoIP audio/video calls as well as messaging chat and file transfer. Many versions are available covering all the principal operating systems like Windows, Macintosh and Linux but also mobile systems. Voice quality decreed Skype success since its birth in 2003 and peer-to-peer architecture has allowed worldwide diffusion. After video call introduction in 2006 Skype became a complete solution to communicate between two or more people. As a primarily video conferencing application, Skype assumes certain characteristics of the delivered video to optimize its perceived quality. However in the last years, and with the recent release of SkypeKit1, many new Skype video-enabled devices came out especially in the mobile world. This forced a change to the traditional recording, streaming and receiving settings allowing for a wide range of network and content dynamics. Video calls are not anymore based on static ‘chatting’ but mobile devices have opened new possibilities and can be used in several scenarios. For instance, lecture streaming or one-to-one mobile video conferences exhibit more dynamics as both caller and callee might be on move. Most of these cases are different from “head&shoulder” only content. Therefore, Skype needs to optimize its video streaming engine to cover more video types. Heterogeneous connections require different behaviors and solutions and Skype must face with this variety to maintain a certain quality independently from connection used. Part of the present work will be focused on analyzing Skype behavior depending on video content. Since Skype protocol is proprietary most of the studies so far have tried to characterize its traffic and to reverse engineer its protocol. However, questions related to the behavior of Skype, especially on quality as perceived by users, remain unanswered. We will study Skype video codecs capabilities and video quality assessment. Another motivation of our work is the design of a mechanism that estimates the perceived cost of network conditions on Skype video delivery. To this extent we will try to assess in an objective way the impact of network impairments on the perceived quality of a Skype video call. Traditional video streaming schemes lack the necessary flexibility and adaptivity that Skype tries to achieve at the edge of a network. Our contribution will lye on a testbed and consequent objective video quality analysis that we will carry out on input videos. We will stream raw video files with Skype via an impaired channel and then we will record it at the receiver side to analyze with objective quality of experience metrics.

El uso de Skype y de las videograbaciones en la docencia de Grado

La comunicación expone la valoración de dos experiencias alrededor de la docencia y el uso de herramientas audiovisuales: Skype para asistir a clase de forma virtual, y la videograbación como útil de aprendizaje que mejora las habilidades comunicativas de los alumnos. El Grado supone la asistencia obligatoria de los alumnos a las clases. Para compensar la presencia personal en el aula, en ocasiones previsibles, se puede realizar una conexión Skype para posibilitar la asistencia virtual. Presentaré los datos y resultados que proporcionan los estudiantes desde 2010-2011. La capacidad para presentarse y explicarse ante un público, personal o virtualmente, gana importancia en el mercado actual. Difícilmente tomamos conciencia de nuestros aciertos y carencias hasta que no nos vemos, hasta que no ponemos la verdad ante nuestros ojos. Los alumnos dan su opinión sobre la utilidad de ver y compartir sus presentaciones grabadas en el aula.

‘Everything’s from the inside out with PCOS’:exploring women’s experiences of living with Polycystic Ovary Syndrome (PCOS) and co-morbidities through Skype™ interviews

Polycystic ovary syndrome is an endocrine disorder affecting 1 in 10 women. Women with polycystic ovary syndrome can experience co-morbidities, including depressive symptoms. This research explores the experience of living with polycystic ovary syndrome and co-morbidities. Totally, 10 participants with polycystic ovary syndrome took part in Skype™ interviews and analysed using thematic analysis. Four themes emerged from the data: change (to life plans and changing nature of condition); support (healthcare professionals, education and relationships); co-morbidities (living with other conditions and depression, self-harm and suicidal ideation) and identity (feminine identity and us and them). The findings highlight the need for screening of women with polycystic ovary syndrome for depressive disorders.

The first time delivery of the first link learning series using Skype and YouTube

Introduction: This case study documented the experiences of informal and service providers who participated in the first time delivery of the First Link Learning Series from May–August 2013 in Newfoundland and Labrador. The aim of this study was to understand how informal caregivers of people with dementia experience this Internet mediated health resource, and how Skype and YouTube can be used as tools for the Alzheimer Society of Newfoundland and Labrador to effectively deliver the First Link Learning Series. Methods: Sources of data included key informant interviews (n=3), pre- study and post-study interviews with informal dementia caregivers (n=2), institutional documentation, field notes, and YouTube analytics. Framework Analysis was used to make meaning of the qualitative data, and descriptive statistics were used to report on quantitative outcomes. Findings: Between 3% and 17% of registered First Link clients attended the learning series sessions, however only two caregivers participated using Skype or YouTube. Framework Analysis revealed three shared themes: access, connection and privacy. Discussion: The themes helped to begin building theory about barriers and facilitators to Internet mediated health resources for informal dementia caregivers. Experiences of service providers using the Internet to support clients served to begin building a case for the appropriateness of these media. A modified version of Dansky et al.’s (2006) theoretical framework for evaluating E-Health research that situates the person/user in the model, helped guide discussion and propose future directions for the study of Internet based health resources for informal dementia caregivers.

How to merge courses via Skype™†? Lessons from an International Blended Learning Project‡

This study reports on an international project in which students taking the course Contemporary Issues in Turkish Politics in spring 2011 and fall 2011 at two institutions of higher education, ‘Gettysburg College’ in the United States and ‘Izmir University of Economics’ in Turkey, worked together in virtual learning environments to complete various tasks as part of their course work. The project employed a blend of traditional and technology-based teaching methods in order to introduce a technology like Skype in a bi-national learning environment in Turkey. Students collaborated and interacted with their international counterparts in two different virtual contexts. First, classrooms in the two countries were merged via Skype three times to conduct classroom-to-classroom discussion sessions on Turkish politics. Second, students were paired across locations to work on several assignments. In this paper, our goal is to present how Skype is used in a bi-national context as a blended teaching tool in an upper-level college course for instructors pursuing a similar exercise. In addition to outlining the process with a focus on Skype discussions and one-on-one student projects, we provide actual assignments and discussion questions. Students’ views elicited through surveys administered throughout the semester are presented alongside anecdotal evidence to reflect how the project was received.

Moodle sobre Moodle - caso de estudo sobre um curso breve, a distância, com tutoria online

Os autores criaram e vêm desenvolvendo um curso para aprendizagem da utilização do Moodle, software online e livre de gestão da aprendizagem e de trabalho colaborativo. Face ao crescimento da utilização do Moodle em Portugal e ao interesse suscitado entre professores e formadores, considerou-se que o cenário era favorável à oferta de um curso breve (cerca de 2 semanas, 21 horas de trabalho dos formandos) que recorresse ao Moodle num modelo de ensino a distância. A interacção, disponibilização de recursos e realização de actividades ocorreram quer de forma assíncrona, usando o Moodle, quer de forma síncrona, com comunicação por voz ou mensagens escritas utilizando o software VoIP Skype. O feedback dado pelos participantes que terminaram o curso sugere que as opções tomadas a nível do modelo de curso breve, estrutura do curso, recursos de aprendizagem e tipo de actividades apresentados, e ainda um elemento de intensa tutoria síncrona, criaram um clima positivo entre tutores e formandos, favorecendo o ambiente informal de aprendizagem e motivando formandos e tutores. Aspectos como avaliação, alguns dos recursos, carga horária sobre tutores e formandos, facilitação da interacção e apoio na concretização do produto final do curso podem ser melhorados, aumentando a eficiência e as aprendizagens no curso. Futuras edições terão estes elementos em conta, incorporarando a experiência dos autores e o feedback dos formandos.
