Competences and skills that will be acquired and learning results. Further information on this link
- Ability to communicate conclusions and the knowledge and rationale underpinning to specialists and non-specialists in a clear and unambiguous way (Basic Competence 9, General Competence 11). - That the students acquire learning skills that enable them to continue studying in a way that will be largely self-directed or autonomous (Basic Competence 10, General Competence 12). - Ability to design, calculate and design products, processes and facilities in all areas of Telecommunication Engineering (General Competence 1). - Ability to design and dimension transport, diffusion and distribution networks for multimedia contents (Specific Competence 4). - Ability to model, design, deploy, manage, operate, administrate and maintain networks, services and contents (Specific Competence 6). - Capacity for planning, decision making and packaging of networks, services and applications considering the quality of service, direct and operation costs, deploying plan, monitoring, safety procedures, scaling and maintenance, as well as manage and ensure quality in the development process (Specific Competence 7). - Ability to understand and apply the working principles and organization of the Internet, the technologies and protocols related with next generation Internet, component models, intermediate software and services (Specific Competence 8). - Ability to solve the convergence, interoperability and design of heterogeneous networks with local networks, access and trunk, as well as the integration of telephony, data, television and interactive services (Specific Competence 9). To acquire specific skills, the subject is coordinated with the Design and Operation of Communications Networks (DORC) as follows: DORC addresses aspects of provision and multimedia content delivery fundamentally at the link and network layers, from the point of view of the organization which deploys the networks. On the other hand, the course of Advanced Multimedia Services addresses transport level and application related with multimedia service, with emphasis on end-to-end communication, from the point of view of the user and the developer of multimedia software.

Learning activities and methodology
- Lectures, aimed to present and promote discussion with students about technology associated to the subject. - Practices in pairs for completing two case studies. Students must make two medium-sized projects to acquire the specific competences of the subject, the capacity for teamwork, ability to self-management and self-learning and decomposition of complex problems into parts. - Personal work and study of the student. Specially oriented to the acquisition of the capacity for self-organization and planning of individual work and learning process.
