P.SCAN(Progressive Scan) Function Unlike a regular Interlace Scan in which two fields of picture information are alternated to create the entire picture (odd scan lines, then even scan lines), Progressive Scan uses one field of information (all lines displayed in one pass) to create a clear and detailed picture without visible scan lines. Hold the P.SCAN button down for longer than 1 second. • The selection switches back and forth between "P.SCAN" and "I.SCAN" each time the button is held down for a minimum of 1 second. • The previous mode is indicated in the display first, followed by the selected mode in about a second. What is Progressive (or Non-Interlaced) Scanning? Interlaced Scan (1 FRAME = 2 FIELDS) Progressive Scan (FULL FRAME) In interlaced-scan video, a frame consists of two interlaced fields (odd and even), where each field contains every other horizontal line in the frame. The odd field of alternating lines is displayed first, and then the even field is displayed to fill in the alternating gaps left by the odd field to form a single frame. One frame, displayed every 1/30th of a second, contains two interfaced fields, thus a total of 60 fields are displayed every 1/60th of a second each. The interlaced scanning method is intended for capturing a still object. The progressive scanning method scans one full frame of video consecutively down the screen, line by line. As opposed to the interlaced scanning process by which a video image is drawn in a series of passes, you get an entire image drawn at one time. The progressive scanning method is desirable for dealing with moving objects. A camera that has the ability to capture moving objects is called a "full frame shutter camera". Note • This function works only on TVs equipped with component video inputs (Y, Pr, Pb) that support Progressive Video. (It does not work on TVs with conventional component inputs, i.e., non-progressive scan TVs.) • Depending on the brand and model of your TV, this function may not work. • This unit only outputs 480i and 480p in progressive scan mode. 17 Connecting the Antennas FM Antenna (supplied) 1 2 3 AM Loop Antenna (supplied) Snap the tabs on the loop into the slots of the base to assemble the AM loop antenna. If AM reception is poor, connect an outdoor AM antenna(not supplied). FM antenna connection AM(MW) antenna connection 1Connect the FM antenna supplied to the FM 75Ω COAXIAL terminal as a temporary measure. 2 Slowly move the antenna wire around until you find a location where reception is good, then fasten it to a wall or other rigid surface. 1Connect the AM loop antenna supplied to the AM and terminals. 2 If reception is poor, connect an outdoor single vinyl-covered wire to the AM terminal. (Keep the AM loop antenna connected). Cooling Fan The cooling fan dissipates the heat generated inside the unit so that the unit can be operated normally. The cooling fan is activated automatically to supply cool air to the unit. Please observe the following cautions for your safety. • Make sure the unit is well-ventilated. If the unit has poor ventilation, the temperature inside the unit could rise and may damage it. • Do not obstruct the cooling fan or ventilation holes. (If the cooling fan or ventilation holes are covered with a newspaper or cloth, heat may build up inside the unit and fire may result.) • If reception is poor, connect an outdoor antenna. Before attaching a 75Ω coaxial cable (with a standard type connector), disconnect the supplied FM antenna. 18 CONNECTIONS
