Presentamos dos modalidades tecnológicas de enseñanza en red: la consolidada y ampliamente utilizada tecnología video-streaming, y el futuro de la comunicación a distancia, la teleinmersión.La primera permite la transmisión de audio/vídeo por la red para que puede ser vista por el usuario en su ordenador personal, desde cualquier lugar que disponga de una conexión a red. La información será recibida y decodificada por el usuario final utilizando cualquier reproductor de los que existen en el mercado.La teleinmersión, por su parte, permite crear espacios virtuales de colaboración entre profesionales, ofreciendo entornos muy cercanos a la realidad. Esta tecnología revolucionará, sin duda, nuestros sistemas de enseñanza en los próximos años, facilitando la interacción profesor-alumno. Es evidente que la formación e-learning aporta a los alumnos y a los docentes grandes ventajas como: menores tiempos de aprendizaje, flexibilidad de horarios y de ubicación geográfica, entre otras.

En el actual contexto social, el uso de los dispositivos móviles se ha masificado de tal manera, que su empleo como herramienta de enseñanza y de aprendizaje en entornos académicos es extremadamente útil. Por lo tanto surge el concepto de Mobile Learning (aprendizaje móvil), que ayuda a los docentes a administrar su práctica docente y a los estudiantes a facilitar su aprendizaje a través del uso apropiado de las Tecnologías de Información y las Comunicaciones TIC; de esta forma la realización de un aprendizaje por medios electrónicos (E-Learning) debe ser centralizada en una plataforma de aprendizaje virtual y conectada con un ambiente multiplataforma de dispositivos móviles con interconexión a la red de comunicaciones de la Universidad. La coexistencia de M-Learning versus E-Learning, van a permitir al docente alinearse con los estudiantes en el uso apropiado de las TIC, para producir beneficios en el aprendizaje a distancia, de tal manera que los recursos tecnológicos puedan ser aprovechados y la comunidad académica se apropie de los recursos a través de nuevas interfaces de comunicación móvil como es el propósito de la investigación realizada para la Universidad Antonio Nariño.

More video streaming technologies supporting distance learning systems are becoming popular among distributed network environments. In this paper, the authors develop a multimedia authoring tool for adaptive e-learning by using characterization of extended media streaming technologies. The distributed approach is based on an ontology-based model. Suppose a well-known teacher is giving a lecture/presentation to his student. Because of time constraints and other commitments, many students cannot attend. The main goal of the authors’ system is to provide a feasible method to record and represent a lecture/presentation using a browser with the windows media services. This system requires flexible support for the modeling of multimedia content models and supports possible interactivity, transfer of streams multimedia data such as audio, video, text, and annotations using network facilities. The authors propose a new approach for the modeling of reusable and adaptable multimedia content. A comprehensive system for advanced multimedia content production is also developed. This approach significantly impacts and supports the multimedia presentation authoring processes in terms of methodology and commercial aspects.

In this chapter we present a novel selective retransmission scheme, based on congestion control algorithm. Our method is efficient in narrowband networks for multimedia applications, which demand higher bandwidth. Multimedia applications are becoming increasingly popular in IP networks, while in mobile networks the limited bandwidth and the higher error rate arise in spite of its popularity. These are restraining factors for mobile clients using multimedia applications such as video streaming. In some conditions the retransmission of lost and corrupted packets should increase the quality of the multimedia service, but these retransmissions should be enabled only if the network is not in congested state. Otherwise the retransmitted packet will intensify the congestion and it will have negative effect on the audio/video quality. Our proposed mechanism selectively retransmits the corrupted packets based on the actual video bit rate and the TCP-Friendly Rate Control (TFRC), which is integrated to the preferred DCCP transport protocol.

Abstract One of the popular internet services in use today is video streaming, either live (live streaming) or pre-recorder. Streaming video is a type of streaming media where data from video files is continuously transmitted over the internet to remote users. This fundamental problem appears to be influenced by the biggest factor which is the limited infrastructure of network resources which causes poor video quality. The process of digital video communication is known to consume quite a large resource, because in general the bandwidth requirements for sending Video and Audio signals. To maintain the quality of the video being played, there are several instruments needed, one of which is a data connection that is required to have Quality of Service (QoS). The parameters used in the measurement of QoS are delay, jitter, packet loss, throughput. This study uses the PPDIO method as a workflow with a Network Lifecycle approach. In this research, there are many factors that influence the quality of video, namely network factors and hardware factors. The test results obtained are not absolute, so it is possible that there will be differences in subsequent testing. Encoding also affects the quality of the video. Bandwidth equalization according to priority when the traffic conditions of all packets are full. Based on a comparative analysis of QoS parameter calculations using HTB and Diffserv methods, a comparison of throughput, jitter and delay does not differ greatly between clients. Keywords: Video Streaming, Diffserv, HTB, QoS Abstrak Salah satu layanan dari internet yang populer digunakan saat ini adalah video streaming, baik secara langsung (live streaming) atau pre-recorder.
