Module goal - Knowledge and skill to be achieved by students |
|
| Students study basic media types, their transformations from aspect of adaptation for relevant transport networks. Through the presentation of the additional processing procedures students get insight into possibilities to achieve interactivity in Multimedia Communication Systems MMCS systems, and introduce new categories of services. The definition of the basic services provides insight into possibilities for development of new applications for MMCS. Suggested examples of MMS networks should direct students towards existing as well as new applications of MMCS applications, and the implementation of practical networks. Students are enabled to apply certain modules and configure the MMCS for different application situations. At the same time special attention is given to digital video safety and protection as well as to modalities of digital rights management (DRM). | |
Syllabus |
|
| Multimedia sources. Methods for creation of multimedia (authoring description, organization, user settings). Requirements for adaptation and trans-coding of the source multimedia information and formats. User interface. Modeling of the multimedia interaction – interactive services. Preparation of the media for multimedia interactive services: MPEG-4; MPEG-7, MPEG-21. Methods of media delivery: unicast, broadcast and multicast. <br> Overview protocols for transport, routing and control relevant for implementation of the MMS: TCP/IP, UDP, SDP, RTP, RTCP, RTSP. Standards for multimedia communication-MHEG/MHP, DAVIC, EPG. Basic types of multimedia services: podcasting of audio and video, broadcasting of TV programs, EPG, VOD. NMMS design: generic system configuration of MM communications; distributed NMMS systems; real-time and non real-time systems. <br> Management and surveillance, traffic planning; IP multicast technology support. Configuration of home networks for acceptance of NMMS. Examples of networks for multimedia communications: IPTV-3 play, DVB reference model of the interactive TV. Configuration of multimedia portals for interactive TV, mobile TV, IP datacasting, IP video-web conferences. Multimedia Peer-To-Peer communication. Telemedicine, Distance learning. Security of the NMMS systems: data hiding, confidentiality, authentication and integrity. Digital rights managements in network multimedia communication system. Protection of digital media. QoS for networks and MMS applications. <br> |

Didactic methods |
|
| Lectures are performed by lecturer and each lecture is followed by presentation of practical problems in appropriate field (42 classes) in a manner enabling students to master knowledge and skills which they should gain through this course, and thus develop abilities to understand the role and place of network multimedia communications and implementation of these services depending of chosen application and communication environment. <br> As part of laboratory exercise students are introduced with basic features of engineering problems, and correlation between model performances and practical results of measuring performed during laboratory exercise (14 classes). <br> Tutorials (14 classes), during which students are under tutor guidance and supervision, have a purpose to enable them to independently analyze, design and simulate NMMC modules and systems, and other examples and problems are also solved. Typical exam problems are also included in order to enable continual check of the preparedness level of students even during the study program execution. <br> |

Exams |
|
| During the course students earn points according to the following system: <br> - Attending classes and tutorials: 10 points, student with more then three absences from lectures and/or tutorials can not get these points. <br> - Home assignments and laboratory exercises bring maximum of 10 points, assuming solving 5 to 10 assignments equally distributed throughout the semester. <br> - Partial exams: two partial exams; each positively evaluated partial exam 20 points. Each partial exam lasts 90 minutes and it is structured as follows: <br> - Answering to simple questions with goal of testing whether student has basic theoretical knowledge; students with correct answers to all such questions earn 5 points; <br> - Solving an open answer problem, with correct answer bringing 10 points; <br> - Solving problems with multiple answers offered, on of answers being the correct one; students with correct answers to all such questions earn 5 points; <br> Students who earned less then 20 points during the semester must retake the course. Students who earned 40 or more points during the semester will take a final exam; This exam consists of discussion of problems from partial exams, home assignments and answers to simple questions related to course topics. <br> Final oral exam provides maximum of 40 points. In order to get positive final grade, students must earn minimum of 20 points in this exam. Student failing to earn the minimum must take the makeup oral exam. Student who earned 20 or more, and less then 40 points during the semester, will have to take the makeup exam. <br> The makeup exam is organized in the following manner: <br> - Written part structured similarly to partial written exam, during which students solve problems in topics they failed on partial exams (less then 10 points); <br> - Oral part structured the same as the oral part of the final exam. <br> Only students who managed to earn total score of 40 or more points in written part of the makeup exam will be allowed to take the oral part of the makeup exam, where the mentioned score consists of points earned through attending lectures, solving home assignments, passing partial exams and passing the written part of makeup exam. Oral makeup exam provides maximum of 40 points. In order to achieve positive final grade students must earn minimum of 20 points in this exam. Student failing to earn the minimum will have to retake the course. Oral makeup exam gives maximum of 40 points. In order to achieve positive final grade students must achieve minimum of 20 points in this exam. Student failing to achieve the minimum will have to re-enroll for this course. <br> |

Aditional notes |
|
| During the written part of the exam students are allowed to use a list of formulas prepared by lecturers, which may be of use in solving problems. It is not allowed to use other notes, books, cell phones or other electronic devices. Problems, which students must solve during the exam, are of the same type solved during the lectures and tutorials. <br> | |
