22 Basic Video Engineering > Review Questions - Pg. 369

CHAPTER 22 Basic Video Engineering This equipment provides automatic compensation for synchronizing inaccuracies on replay or imperfect sync pulses from cameras. They store the video information and then clock it out at precisely timed intervals in perfect synchronism with the master sync-pulse rate. These units often offer additional facilities, such as freeze frame, digital enhancement, noise reduction, and color correction. REVIEW QUESTIONS 1. 2. 3. 4. 5. What are the three areas that engineers are responsible for? What are some of the types of equipment used to test the quality of the video signal? How does "shading" enhance the quality of the video signal? Why does a camera need to be white-balanced? Why is it important to synchronize video signals?
