General information about the exams

Tue, 09 Jun 2026 21:59:36 +0300

Written exams for the Multimedia Technology class are 2 hours long (11:30‐13:30, January 17, Rooms A24 and A25, Antoniadou wing).The exams are open book: you can bring with you any printed or handwritten materials you want, but NOT mobile phones or computers. Do bring a calculator, as some exercises may require tedious calculations.

The exam questions will be provided in Greek and English, and your responses can be in either language; you will not be graded based on your English (or your Greek) skills. The exam questions will amount to more than 60 points, and you can answer them all, but your grade will be no more than 60 points - the remaining 40 points are from your project. All the material we covered is in eclass.

Most of the exam questions will be exercises similar to those from the tutorials, while a smaller number of questions (for fewer points) will be similar to the review questions we saw in class. You do not need to memorize anything, but it is best to have some experience solving the exercises from the tutorials. If there are multiple answers to an exercise (example: different valid EDF or RMS sequences, different ways to calculate the same thing), one correct answer is enough.

Class evaluations

Thu, 28 May 2026 01:53:05 +0300

Do not forget to submit a class evaluation! You can evaluate the class until May 31st (Erasmus students until June 6), via e-grammateia; however, the evaluations are anonymous. I am especially interested in any comments that you may have (what you liked, what you disliked, what could be done differently).

Final project submission

Thu, 28 May 2026 01:47:56 +0300

Thanks for all the presentations! If you want to, you can resubmit your project by Monday June 1st (23:55) via eclass, replacing your existing submission. You do not have to resubmit if you do not have something to add.

Make sure you have submitted the sources of your project, either via eclass, or via google drive or onedrive (put the link to these in your eclass submission). Also, make sure your report lists all the members of your team. Do not send deliverables, links or sources via e-mail; only use eclass to ensure that the project has been submitted.

Project Presentation Schedule

Sun, 24 May 2026 15:20:49 +0300

The schedule for project presentations is available in the General folder of the Documents area (here). Each hour has 4 presentations, so you have 15 minutes to present your work. You can attend all presentations, but you should be at least present at the beginning of the hour of your presentation slot (so that we can switch the order, if needed). For those that had not selected a slot, I assigned them to the slots that were empty. The links for the Teams meetings are:

Monday: Multimedia Technology Presentations (25/5) | Meeting-Join | Microsoft Teams

Tuesday: Multimedia Technology Presentations (26/5) | Meeting-Join | Microsoft Teams

Wednesday: Multimedia Technology Presentations (27/5) | Meeting-Join | Microsoft Teams

Project Presentation Slots (corrected)

Sat, 23 May 2026 02:11:26 +0300

Project presentations will take place via Teams, in 15 minute slotson Monday 25, Tuesday 26 and Wednesday 27 of May. The presentations are public, so you can all attend. As we had 35 project proposals, we have allocated 9 one hour slots for presentations, with 8 projects per slot: Monday 25 12:00-13:00, 13:00-14:00 and 14:00-15:00, Tusday 26 11:00-12:00, 12:00-13:00 and 13:00-14:00, and Wednesday 27 14:00-15:00, 15:00-16:00 and 16:00-17:00. We have created one group in e-class for each of these slots (with a capacity of 4), so one (only!) member of your groups should enroll in one of these groups; we will announce an exact schedule for each day via eclass, when the groups fill up. Note that some of these slots may clash with other classes or tutorials, so make sure to choose a slot that you can actually attend.

I will send the teams link when I have a schedule ready. The deadline to submit your completed project (if you want to make additions) will also be finalized when the schedule is complete.

Project submission and project presentations

Tue, 19 May 2026 00:32:54 +0300

The submission deadline for the projects is Friday, May 22nd; you need to submit a working project by Friday, so that I can schedule the presentations. However, you will be allowed to submit a revised version after the presentations (by the end of May or so), to address issues, comments and suggestions.

On Saturday May 23rd, I will open up a number of groups corresponding to presentation slots, so that you may reserve a slot. If we have too many projects for the scheduled class and tutorial hours, we will add some extra hours to fit everybody. The presentations will be made via Teams, and they will be public; you are all welcome to attend as many as you can and comment on them.

The presentation slots will be 12-15 minutes (exact times will be announced with the schedule). You can start your presentation with a synopsis of your project (could be a short powerpoint) and then show a demo of your project, or you can show a demo and explain on the way what you have created. If you are demonstrating a game, you may want to show a pre-recorded video - this allows you to show different parts of the game, without going through the entire game, and provides better synchronization with sound. Please test your demo in advance, to ensure that screen sharing and audio works properly (when you share your screen or a window, there is a button that allows you to share the audio from that window) and that you can complete it on time. We will also be testing all projects offline, but the demo allows for spontaneous questions during the presentation. More info on how projects are graded are in the grading overview (here), while more info on the report and submission requirements are on the project topics announcement (here).

Reminder: Tutorial #3: Monday May 18, 13:00-15:00

Sat, 16 May 2026 15:29:18 +0300

The last tutorial (#3) will be held on Monday May 18, during the regular class slot (13:00-15:00 on Room Y3). On Monday May 18, I will not have office hours 12:00-13:00 - come see me on Tuesday if you want to see me in person, or send me an e-mail to arrange a Teams meeting.

Tutorial #3: Monday May 18, 13:00-15:00 (change of date & time)

Sat, 09 May 2026 17:14:12 +0300

The last tutorial (#3) will be held on Monday May 18, during the regular class slot (13:00-15:00 on Room Y3), as on May 13 we have student council elections and no classes will be held. Note the change of date and time from the previous announcement!

We will not have another tutorial, but we will use the tutorial slot for project presentations on May 27 (along with the regular class slots on May 25 and 26).

Short presentation of MS in Computer Science next Monday May 4

Tue, 28 Apr 2026 13:19:45 +0300

During next class (Monday May 4), at around 14:00 we will have a short presentation of the MS in Computer Science program by Professor and Program Director Iordanis Koutsopoulos. You are all are welcome!

Slight delay today

Tue, 28 Apr 2026 11:17:10 +0300

I will be 10 minutes late today, there were a couple of trucks closing the street outside AUEB (Derigny) creating a huge mess.

Grading Details + Project Submissions + Review Questions

Tue, 21 Apr 2026 13:48:06 +0300

To better prepare for your project submissions and the written exams, you can read the course grading guide available in the Documents are in the General folder (here). Please make sure you have read the project grading criteria, to prepare your submissions properly. Also note that the review questions presented at the end of each chapter in class will not be uploaded to eclass (these are a bonus for those attending the lectures).

Multimedia Technology Tutorial #2 slightly late

Wed, 01 Apr 2026 15:00:21 +0300

Due to heavy traffic, the tutorial will start a bit later than planned - but do not worry, the instructor is coming!

Reminder: Tutorial #2: Wednesday April 1, 15:00-17:00 (tomorrow) + note on announcements

Tue, 31 Mar 2026 13:15:06 +0300

This Wednesday (tomorrow, April 1st) we will have the second tutorial for the class. All tutorials will be held on Room X (basement, old building), 15:00-17:00.

Incidentally, the e-mail server in eclass has a long-running issue with getting flagged as a spam server with Microsoft-issued e-mails (windowslive, hotmail, live, etc.), which means that if you have such an e-mail, you are not getting the announcements. So, tell your friends!

Tutorial #2: Wednesday April 1, 15:00-17:00

Tue, 24 Mar 2026 15:08:58 +0300

Next Wednesday we will have the second tutorial for the class. All tutorials will be held on Room X (basement, old building), 15:00-17:00.

No class and office hourse on Tuesday, March 24th

Mon, 23 Mar 2026 16:24:34 +0300

Due to AUEB's celebration of the Greek revolution of 1821 on Tuesday, March 24th (12 noon to 2 pm), the class on the 24th is postponed - it would have to be a single hour class, at best. If you want to see me this week and did not make it on Monday, send me an e-mail, I will be at school on both Thursday and Friday.

Project topic feedback (correction: do not send new proposals if you got 10)

Thu, 19 Mar 2026 13:16:04 +0300

I have added some feedback and a "grade" to your projects. If your grade is 10, your proposal sounds reasonable to me. If your grade is 5, your proposal is either too vague to assess, and either too simple or too complex for your group size, so I suggest working a bit more on it. If your grade is 0, your proposal does not fit the class, you have to do something else. If you got 0 or 5, you can send me your revised ideas by mail. If you got a 10, you do not need to do anything extra.

Tutorial #1: Wednesday March 18, 15:00-17:00

Mon, 16 Mar 2026 12:24:42 +0300

This Wednesday we will have the first tutorial for the class. All tutorial will be held on Room X (basement, old building), 15:00-17:00, but since we are sharing the room with another class, I will send an announcement when we do have a tutorial (we will do around 4 in total).

Project topics and deadlines announced

Mon, 09 Mar 2026 03:13:40 +0300

A list of project topics, as well as the details on what you should hand in and when, is available in the Documents area of eclass. We will talk more about the projects on Monday March 9, during class. The deadline to submit your proposals via the Assignments tool of eclass is Sunday March 15.

Tutorial slot finalized

Tue, 24 Feb 2026 15:58:37 +0300

The tutorials will be held on (some) Wednesdays, 15:00-17:00 (X). We will announce a program when we arrange the details with the other class sharing the classroom.

Tutorial slot (reminder, for greek students only)

Mon, 23 Feb 2026 15:56:43 +0300

Για το φροντιστήριο, σκεφτόμαστε να το κάνουμε Τετάρτη 3-5 (εναλλάξ με τα Δίκτυα Υπολογιστών του κ. Σταμούλη στο 6ο εξάμηνο). Επειδή την ίδια ώρα διδάσκεται το μάθημα Εννοιολογική Μοντελοποίηση και Οργάνωση Γνώσεων από τον κ. Κωνσταντόπουλο, αν σκέφτεστε να παρακολουθήσετε το μάθημα του κ. Κωνσταντόπουλου, στείλτε μου ένα μήνυμα, ώστε να βρούμε κάποια άλλη ώρα. Αν δεν υπάρξει κανένα μήνυμα ή αναφορά στη διάλεξη στις 24/2 για σύγκρουση, το φροντιστήριο θα οριστικοποιηθεί για την ώρα αυτή.

Tutorial Slot (question for Greek students only)

Wed, 18 Feb 2026 22:10:56 +0300

Λόγω έλλειψης αιθουσών, σκεφτόμαστε να μοιραστούμε την ώρα φροντιστηρίου με το μάθημα Δίκτυα Υπολογιστών του κ. Σταμούλη (δηλαδή, κάποιες εβδομάδες να φροντιστήρια στο ένα μάθημα, και κάποιες στο άλλο). Την ίδια ώρα όμως (Τετάρτη 3-5) διδάσκεται το μάθημα Εννοιολογική Μοντελοποίηση και Οργάνωση Γνώσεων από τον κ. Κωνσταντόπουλο. Αν σκέφτεστε να παρακολουθήσετε το μάθημα του κ. Κωνσταντόπουλου, στείλτε μου ένα μήνυμα, ώστε να βρούμε κάποια άλλη ώρα.

Multimedia Technology 2025-2026

Tue, 17 Feb 2026 01:47:21 +0300

The class slides for today (and the next couple of lectures) are in the Documents area of eclass, in the Course Slides folder. In the General folder you can find the course announcement and the details on grading. There will be an announcement when we get a classroom for the Tutorials and plan the first one - we will do 4-5 tutorials, so we will not have a tutorial every week.
