Contextualization:

Interactive Multimedia Services is a mandatory course within the Telecommunication Systems and Services field. It is taught by personnel of the Informatics Department during the spring semester within the third course of the Bachelor´s Degree in Telecommunication Technologies and Services Engineering. The course is organized in two weekly lectures, two weekly labs, seven seminars and two group tutorials.

The student will study the operation of interactive multimedia services. Special attention is paid to streaming of continuous media (audio and video), communication systems (instant messaging, voice over IP and videoconference) and the protocols involved.

Requirements:

No prerequisite is necessary to enroll in this course.

Competences and learning results:

Interactive Multimedia Services encourages the student to acquire the following competences:

CR 1

Capability to autonomously learn new knowledge and techniques oriented to design, develop and exploit telecommunication systems and services.

CR 12

Knowledge and use of concepts related to network architectures, protocols and communication interfaces.

CR 13

Capability to differentiate the concepts of link and transport networks, circuit and packet switching networks, mobile and fixed-line networks, and distributed systems and network applications, voice services, data, audio, video and interactive multimedia systems.

 

The learning outcomes are the following:

RA-12.12

To assess the technological alternatives to provide a service considering some requirements and the applicable legal background, recommendations, etc., selecting the most appropriate according to technical, economic or other types of criteria.

RA-12.13

To describe and document the solution to a problem and project related to communication systems.

RA-12.35

To work in teams to design and assess the performance of interactive multimedia systems.

RA-12.37

To have initiative to propose and assess innovative alternatives to design, configuration and deployment issues of voice services, data, and interactive multimedia.

RA-12.38

To communicate effectively the characteristics of designed services using oral and written communication.

Methodology and work plan:

Interactive Multimedia Services will be taught by means of:

  • Lectures: Main concepts of the course are presented in detail.
  • Seminars: Problems are solved, as well as questions about the concepts presented in the lectures. In addition, exercises or other tasks may be done.
  • Labs: The main concepts of the course are trained in a computer to acquire skills in the use of tools.
  • Group tutorials: Teachers solve students’ queries in small groups. If required by the teacher, other activities may be done in these sessions, such as teamwork organizing and monitoring.
  • Student work: Individual and teamwork, as well as preparing the evaluation sessions.

Teachers expect each student to devote the following hours to each session in order to acquire the expected skills trained in the course.

Exceptionally, should sanitary conditions require it, non-classroom teaching activities may be included. In that case, students will be informed accordingly.

Assessment of students learning:

The mark of the student is calculated as:

Final mark = 0.3 x Theory part + 0.1 x Seminars + 0.3 x Labs + 0.3 x Teamwork

 

The final mark must sum up at least 5 points out of 10 for the student to pass the course. In addition, it is necessary to obtain a minimum mark:

  • Four points out of ten in the theory part.
  • Three points out of ten in the labs (laboratory part).
  • Three points out of ten in the teamwork.

If the student does not reach the minimum mark in all the parts, the final mark will be computed as the minimum between the result of the previous equation and 4.5.

 

Assessment of the theory part

The assessment of the theory part of the course is computed differently in the ordinary and in the extraordinary evaluations:

  • Ordinary evaluation. Two exams will be done during the course in order to assess the work related to the theory part. These exams will be done individually and will be included in the in-class activities.

The mark of this part is calculated as the geometric mean of the mark of the two exams. Extraordinary evaluations. The theory part of the course will be evaluated by means of a final exam. The mark of the theory part of the course is the mark obtained by the student in this final exam.

The mark of the theory part of the course in the ordinary evaluation is valid for the extraordinary evaluations of the same academic year.

 

Assessment of the seminars

The assessment of the seminars is computed only in the ordinary evaluation considering some optional team assignments.

The mark of the seminars in the ordinary evaluation is valid for the extraordinary evaluations of the same academic year.

 

Assessment of the laboratory part

The assessment of the laboratory part of the course is computed differently in the ordinary and in the extraordinary evaluations:

  • Ordinary evaluation. Two exams will be done during the course in order to assess the work related to the laboratory part. These exams will be done individually and will be included in the in-class activities.

The mark of this part is calculated as the geometric mean of the two exams. This mark is subjected to the student to attend at least 80% of the laboratory sessions of the course. Otherwise, the mark of the laboratory part of the course will be 0.

  • Extraordinary evaluation. The laboratory part of the course will be evaluated by means of a final exam. At least, the minimum mark in the theory part is required to the take the extraordinary laboratory exam.

The mark of the laboratory part of the course in the ordinary evaluation is valid for the extraordinary evaluations of the same academic year.

 

Teamwork assessment

During the course, a task to be developed with classmates will be assigned to the student. Students will form teams of three or four members of the same group tutorial. The topic of the task will be proposed by the teacher. At the end of the course, a report must be sent to the teacher and a public presentation must be carried out. The presentation will be carried out by one or more members of the team chosen at the beginning of the presentation. Thus, all the members must attend the presentation of their teamwork.

The mark for each student in the team may be different depending on the participation of the student. The mark in the teamwork of the members that do not actively attend their teamwork presentation will be 0.

The mark of the teamwork is valid for the extraordinary evaluations of the same academic year. There is no chance to do the teamwork in the extraordinary evaluations.

 

Differentiated assessment

Two exams will be mandatory in all evaluations. Firstly, a final exam based on the theory part of the subject, between 0 and 5 points. Secondly, a final laboratory exam, between 0 and 5 points. To sit the laboratory exam, the student must pass the theory exam. A minimum mark of five points is required in both exams to pass the course.

 

Exception

Exceptionally, should sanitary conditions require it, non-classroom evaluation methods may be included. In that case, students will be informed accordingly.
