85RQT9385ReferencePan&Scan/LetterboxIn general, DVD-Video are produced with the intention that they beviewed on a widescreen television (16:9 aspect ratio), so imagesoften don’t fit regular (4:3 aspect ratio) televisions. Two styles ofpicture, “Pan & Scan” and “Letterbox”, deal with this problem.Playback control (PBC)If a Video CD has playback control, you can select scenes andinformation with menus.(This unit is compatible with version 2.0 and 1.1.)Progressive/InterlaceThe PAL video signal standard has 576 (or 625) interlaced (i) scanlines, whereas progressive scanning, called 576p (or 625p), usestwice the number of scan lines. For the NTSC standard, these arecalled 480i (or 525i) and 480p (or 525p) respectively.Using progressive output, you can enjoy the high-resolution videorecorded on media such as DVD-Video.Your television must be compatible to enjoy progressive video.Panasonic televisions with 576 (625)/50i · 50p, 480 (525)/60i · 60pinput terminals are progressive compatible.ProtectionYou can prevent accidental deletion by setting writing protection ordeletion protection.RGBThis refers to the three primary colours of light, red (R), green (G),and blue (B) and also the method of producing video that uses them.By dividing the video signal into the three colours for transmission,noise is reduced for even higher quality images.Sampling frequencySampling is the process of converting the heights of sound wave(analog signal) samples taken at set periods into digits (digitalencoding). Sampling frequency is the number of samples taken persecond, so larger numbers mean more faithful reproduction of theoriginal sound.ThumbnailThis refers to a miniature representation of a picture used to displaymultiple pictures in the form of a list.WMA ([EH69] [EH59])WMA is a compression format developed by Microsoft Corporation.It achieves the same sound quality as MP3 with a file size that issmaller than that of MP3.1080iIn one high definition image, 1080 (1125) alternating scan lines passevery 1/50th of a second to create an interlace image. Because1080i (1125i) more than doubles current television broadcasts of480i (525i), the detail is much clearer and creates a more realisticand rich image.1080pIn one high definition image, 1080 (1125) scan lines pass at thesame time every 1/50 th of a second to create a progressive image.Since progressive video does not alternate scan lines like interlace,there is a minimal amount of screen flicker.720pIn one high definition image, 720 (750) scan lines pass at the sametime every 1/50 th of a second to create a progressive image. Sinceprogressive video does not alternate scan lines like interlace, thereis a minimal amount of screen flicker.Pan & Scan: The sides are cut off so the picturefills the screen.Letterbox: Black bands appear at the top andbottom of the picture so the pictureitself appears in an aspect ratio of16:9.
