This course offers a description of nowadays multimedia services and evolution. The network architectures that allow bearing those services as well as the protocols involved are described. The standards evolution is considered, starting from those ones standardized from the ITU-T (H.248, H.323), protocols included in the IP architecture (RTC, RTCP, SIP, etc.), and in new approaches such as DASH and WebRTC. The infrastructures required to deploy multimedia services, such as IPTV, the IMS for mobile networks and multicast distribution of content are analysed. The main features of the traffic generated by the multimedia services are also detailed by focusing into quality of service and security aspects (network and data) of nowadays technologies.
The practical content includes the design and configuration of real time multimedia systems and the monitoring and analysis of multimedia traffic. In addition to the development of skills in the communication of information, ideas, problems and solutions in the field of engineering, they must respond to the results obtained as described in the methodology section, by means of interviews with the teacher and the submission of reports after each practical .

Throughout all the activities of the course, attention will be paid to two fundamental aspects in relation to inclusion and equity (SDG-4), which will also be part of the participation aspect evaluation:
- Promoting the use of inclusive language in both large and small group lectures, both written and oral, and attending to activities of various kinds (lectures and seminars where the student can be the instructor, practice with hardware and software, reports and tests with multiple choice questions) focused on being equitable with the different learning abilities of the student.
- Attendance, as well as active, respectful and responsible participation, either to raise doubts or to respond to the teacher's requests or questions, will be evaluated positively in its corresponding factor.
Large group lectures
The methodology to be followed in large-group lectures will be a mixture of introductory activities, lectures and the presentation of theory and general examples in the classroom designated for the course by the centre.
In addition to the presentation of the theoretical content of the course, the ability to collect and interpret data and handle complex concepts within Advance Multimedia Services will be developed and promoted, in order to make judgements that involve reflection on ethical and social issues. Indeed, during these sessions the activities introduced have as a main goal to motivate the research and critical analysis about nowadays technologies involved in the deployment of multimedia services as well as their effect in the society life style regarding communication, such as the network neutrality, changes due to the multimedia inclusion in the social networks, etc.
Students must follow the lecturer's presentation with the material provided for this purpose through the PLATEA platform, whether notes or slides, which must be completed with their own notes and with the subsequent review of the basic and/or recommended bibliography.
The autonomous work of the student should focus on the revision of the concepts and theoretical aspects seen in class, exercises completion, as well as their study with the material provided by the lectures, the student's notes and bibliography.
Exercises/problems
Exercises/case studies resolutions in groups and seminars about relevant contents related with the practical sessions will be introduced. During these sessions the student will be encouraged to develop their skills of solving a specific problem associated with the multimedia distribution of content through the use of different available technologies. They should also have to analyse the possible problems that can be encountered due to differences in the format distribution, network operators, services providers to exchange multimedia data and control and manage the distribution in worldwide contexts.
Lab Sessions
Prior to these sessions, students in pairs will have to complete some autonomous work in preparation for the practices supported by a script that will be published in PLATEA, which will include both the autonomous work activities and support information for carrying them out, as well as a detailed description of the tasks to perform in the laboratory and the associated information that must be recorded and shared with the lecturer during their final supervision
During these sessions the active participation developing supervised practices about applications configuration and traffic measurements is promoted, but also the development of a real time multimedia application via following a PBL approach. These sessions are designed to make the student to get used to update their knowledge about new technologies as well as to be able to formulate critical analysis about the main benefits or drawbacks of their deployment compared to other technologies.
Besides the initial practices preparation, the autonomous work will focus on the preparation of the documentation to submit, as well as on completing the unfinished work started in the laboratory. Special emphasis will be placed on the need for continuous training and to undertake this activity independently throughout their professional life, as well as on the ability to keep up to date with new developments in the field of Information Technology Engineering, with a more technical approach.
Group tutorials
Group tutorials will be used to resolve doubts, monitor and supervise work and exercises, as well as to attend and participate in the different seminars planned for the course, in addition to talks, conferences, workshops and/or seminars, designated by the lecturer, with the aim of completing and updating training and obtaining general, transversal and/or specific competences defined for this activity, such as the value of continuous training, entrepreneurship or the review of technological innovations in the course.
Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support
At the end of the term the students can choose between two assessment modalities: CONTINUOUS ASSESSMENT or FINAL EXAM.
Continuous Assessment
The Continuous Assessment modality will be carried out according to the outcomes of the activities planned during the term and described in the section "Methodology and activities", in addition to those described in the section "Detailed description of the Continuous Assessment" that will be weighted by considering the aspects and percentages detailed in the above table.
In order to pass the course, students must obtain a grade equal to or higher than 5.0 out of 10 in the overall results, but with the condition of obtaining a grade equal to or higher than 4.0 in each of the individual aspects assessed. Otherwise, in the case of failing any of these two conditions (a grade equal to or higher than 5.0 out of 10 in the overall results, or equal to or higher than 4.0 in any of the assessed aspects), the student must follow the Final Exam modality.
Final Exam
In the FINAL EXAM modality, an exam will be held on the day set for the course within the exam period, which will cover all the course contents, ensuring that students have acquired the competences and learning outcomes established for the course. The two parts of this written exam are weighed as follows:
- Part 1: Attendance and participation, theoretical concepts and completion of study cases or exercises assignments (S1, S2, and S3): 70%.
- Part 2: Laboratory/ computer practical work (S4): 30%.
The specific conditions, as well as the material and/or documentation that may be used in the Final Exam will be established by the lecturer.
In order to pass the course, students must obtain a grade equal to or higher than 5.0 out of 10 in each of the two parts.
Students who have passed the S4 aspect (laboratory/computer practical work) of the course, through CONTINUOUS ASSESSMENT, with a grade equal to or higher than 5.0 out of 10, will not have to take Part 2 corresponding to this aspect in the exam. The same grade obtained in the CONTINUOUS ASSESSMENT will be assigned to this part.
The parts passed at each exam attempt will be maintained until the end of the academic year.
Detailed Description of the Continuous Assessment System
For those students whose assessment is carried out on a continuous basis, this will be based on the monitoring and carrying out of the activities included in the four categories presented in the Assessment System, which make up the total of the assessable elements of the subject:
- S1, Attendance and active participation (10%).
- S2, Theoretical concepts (30%).
- S3, Exercises, cases and exercise (30%).
- S4, Laboratory/computer practice (30%).
Each of these aspects will be detailed in the following subsections:
Attendance and Active participation: 10%. The level of attendance will be computed considering practical (reduced groups) and theoretical/problems sessions (lectures with theory groups). The level of active participation will be evaluated via the students' participation and autonomous work in various proposed activities within lectures and lab sessions. The following competences will be evaluated with this method: CB6, CB7, CB8, CB9, CB10, CG1, CG2, CG3, CG4, CG5, CG7, CG9, CT1, CT2, CT3, CT4, CT6. A positive evaluation assessed with this method will mean that the students have achieved the following competencies or learning results: 34, 40, 41.
Theoretical concepts: 30%. During the semester there will be some tests or activities to assess with a continuous evaluation the theoretical questions developed during lectures. In addition, the questions proposed as autonomous work or through PLATEA (LMS) will be included as part of this evaluation. The following competences will be evaluated with this method: CB9, CB10, CG2, CG3, CG4, CT1, CT2, CE4, CE6, CE7, CE8, CE9. A positive evaluation assessed with this method will mean that the students have achieved the following competencies or learning results: 27, 28, 31, 33, 34, 40, 41, 43.
Exercises and case studies: 30%. During the semester there will be questions/tests or activities about the problems and practical cases studied in the lectures. In addition, the development and presentation of the material related to activities proposed through the LMS will be also considered as part of the continuous evaluation. The following competences will be evaluated with this method: CB6, CB7, CB8, CB9, CB10, CG2, CG3, CG4, CG5, CG7, CG9, CT1, CT2, CT3, CT4, CT6, CT7, CE4, CE6, CE7, CE8, CE9. A positive evaluation assessed through this method will mean that the students have achieved the following competencies or learning results: 27, 28, 31, 33, 34, 40, 41, 43.
Lab/computer practical sessions: 30%. This item takes into account the development of the design practices and the documentation requested. The following competences will be evaluated with this method: CB6, CB7, CB8, CB9, CB10, CG2, CG3, CG4, CG5, CG7, CG9, CT1, CT2, CT3, CT4, CT6, CT7, CE4, CE6, CE7, CE8, CE9. A positive evaluation assessed with this method will mean that the students have achieved the following competencies or learning results: 27, 28, 31, 33, 34, 40, 41, 43.
The grade system is ruled by RD 1125/2003 of 5th September, which established the European Credits System for the official university studies.
