Universidad de Jaén

In this subject the student will be given an overview of the application protocols and multimedia data transport. You will also see the set of protocols used in multimedia session management.

The student will be equipped with the ability to keep up to date with new developments in science and technology, especially in this type of subject, which is so closely linked to a dynamic environment such as telecommunications, and specifically telematic engineering.

PRACTICES

The practical part of the course consists of laboratory practice and is compulsory. In addition, communication skills, information, ideas, problems and solutions will be developed in the field of engineering and society in general through processes of documentation delivery or oral presentations.
With regard to work organisation, collaboration and teamwork will be encouraged through the design of the internship itself.  

PRACTICE 1. Audio and video traffic analysis with Wireshark protocol analyzer: HTTP, RTSP and VoIP.

PRACTICE 2. Study of streaming servers for TV on demand.

PRACTICE 3. Deployment and setup of streaming servers over RTP.

• Configuration of multimedia sessions.
• Performance evaluation of the multimedia applications used for different video codecs.
• Capture and analysis of multimedia traffic with Wireshark

PRACTICE 4. Configuration of IP multicast for LAN and MAN.

Lecture or master classes (big groups): will be supported by introductory activities, master classes and the presentation of theory and examples in the classroom designated for the subject by the centre. In addition to the presentation of the theoretical contents of the subject, the capacity to collect and interpret data and to manage complex concepts within Telematic Engineering will be developed and strengthened, in order to issue judgments that imply reflection on ethical and social issues.

Lab Sessions: Active participation developing supervised practices about applications configuration, traffic measurements and real time multimedia applications programming.

The collective tutorials will be used in the resolution of doubts, follow-up and supervision of the works and exercises as well as attendance and participation in different seminars, talks, conferences, workshops and/or conferences, designated by the teacher, with the aim of completing the training and the obtaining of general, transversal and/or specific competences defined for this activity, such as the value of continuous training, entrepreneurship or the revision of new technological developments in the field.

Assistance, as well as active, respectful and responsible participation in the activities mentioned above, will be evaluated according to the provisions of section 7 of this guide.

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

There are two ways to evaluate the subject: through global evaluation or the final evaluation.

5.1 OVERALL EVALUATION

This assessment method is organised according to the activities described in the previous table. The evaluation process consists of:

- The evaluation of the tasks defined in the Teaching Guide during the teaching period.

- A final written Exam during the Examination period.

The assessment aspects evaluated in both parts and their contribution to the final mark are summarized in the following table:

Marks obtained during the teaching period (as a record of the continuous evaluation process) will be kept until the end of the academic year.

Written examination:

Students must take a written exam that evaluates the theoretical and operational aspects of the subject (S2 and S3) at the end of the semester (at the date established in the exam period). This final examination is conducted to assess the extent to which students have acquired all the competencies and learning outcomes established for these aspects. The weight of this examination is 50% of each of the assessed aspects (S2 and S3).

Any book, note, documentation or equipment that is allowed for this final exam has to be approved by the teacher.

Final evaluation:

The students must obtain a mark higher or equal to 4 (out of 10) in S4 to keep this evaluation method (Laboratory or computer practical work). The students will pass the subject through this evaluation method by getting a mark higher or equal than 5.0 out of 10 in the overall result (global evaluation and written exam), but with the condition of obtaining a mark higher or equal to 4.0 in the written Exam and in S4.

The students can renounce to the global evaluation at any time, but they can choose it again. Thus, they will be evaluated only by the final evaluation method.

5.2 FINAL EVALUATION

This kind of evaluation is based in only one written exam that evaluates all the aspects of the subject, by assessing the students' acquisition of all the competences and learning outcomes established in the subject. This exam will take place during the Examination period on a date established by the centre. The final exam is weighted in the following way:

- Participation (S1), Theoretical concepts (S2) and Exercises, problems and study cases (S3): 70%.

- Laboratory and computer practical work (S4): 30%.

In order to pass the subject, the student must have marks higher or equal to 5.0 out of 10 at each part of the final exam.

The students who have already fulfil the requirements of aspect S4 (Laboratory or computer practical work) through the global evaluation, by obtaining a mark higher or equal to 5.0 out of 10 do not have to make this part in the final evaluation.

Those aspects successfully completed with a mark higher or equal to 5.0 will be considered passing during that academic year.
