- Test 3 will be on Wednesday, November 7 and will cover and will cover Chapters 6 - 7 as well as some basic number conversions, which we will review in class on October 31st.
- The test will consist of a series of multiple choice and short-answer questions, including one or two math questions.
- The test will be administered at the beginning of class. No make-ups will be given without an excused absence (please remember that traffic and job-related activities are not excused absences), so please be on time.
- You may bring a pocket or graphing calculator and one 8 1/2 x 11 sheet of paper with handwritten notes only, front and back. No calculators with QWERTY keyboards allowed.
- Most of the information in the study guide below was given in class lectures and are reinforced in the reading except where indicated. Any topics not covered in the reading are hyperlinked. (If you see something here that is not in the book, please let me know.) However, please don't hesitate to contact me if you're still confused about something.
- Practice number problems are available under the Content tab on D2L.
- Know what Persistence of Vision is and why it makes film and video possible.
- Know the difference between digital and analog video and the advantages of each
- Digital - multiple channels in the same signal, easier to send high-definition pictures
- Analog - doesn't immediately cut out when there's interference
- Know that we use the NTSC analog video standard and ATSC digital video standard in North America
- Know the difference between interlaced and progressive video and the advantages of each
- Know what the combing effect is
- Know what safe zones are
- Know how the YUV color system works
- Know what frame size, frame aspect ratio and pixel aspect ratio are
- Given a frame size and a pixel aspect ratio, compute the frame aspect ratio
- EXAMPLE: If frame size = 720x480 and pixel aspect ratio = 0.9, then the frame aspect ratio is (720 * 0.9) x 480 = 640 x 480 = 4:3.
- Know why such players sometimes take awhile to start playing (i.e. what does "buffering" mean?)
- Know the difference between spatial and temporal compression and the advantages of each
- Know the difference between temporal compression differencing (MPEG-2 in your book) and temporal compression vectoring (MPEG-4 in your book) and that the latter is difficult for video because computers cannot recognize distinct objects in video frames (NOTE: You do NOT need to know anything about iFrames/pFrames/bFrames)
- Given two different videos, decide which one is smaller when using temporal compression differencing
- Know what a codec is and the difference between symmetric and asymmetric codecs
- Know what macroblocking is
- Know what telecine is
- Know what screen tearing is
- Know how YouTube deals with limited bandwidth
- Know what a video capture card is and why you need one to capture video
- Know what FireWire cables and ports are
- Know that video can be recorded to miniDV tapes, DVDs, memory cards and hard drives
- Know what a CCD is
- Know what nonlinear editing means (you don't have to distinguish between the four types of nonlinear edits described in the book)
- Know what keying means, specifically with regards to Chroma Key
- Be familiar with the following video transitions: straight cut, fade in, fade out, cross dissolve
- Given a base numbering system and a given number of digits, tell how many things you can count.
- Know how to count from 0 to 7 in decimal and 0 to 255 in hexadecimal.
- Jim Rowan is the former course coordinator for ITEC 2110. He has PowerPoint slides and recorded lectures that offer a different perspective on the material in this course.
