ReferenceVQT2J65118GlossaryPan&Scan/LetterboxIn general, BD-Video and DVD-Video are producedwith the intention that they be viewed on awidescreen TV (16:9 aspect ratio), so images oftendon’t fit regular (4:3 aspect ratio) TVs. Two styles ofpicture, “Pan & Scan” and “Letterbox”, deal with thisproblem.Progressive/InterlaceInterlace is a conventional image signal that displaysthe image in 2 phases by splitting the display into oddand even scans.Progressive will display whole image in 1 scan.Therefore, it will give High Definition image withoutflickering compared with interlace.ProtectionYou can prevent accidental deletion by setting writingprotection or deletion protection.Sampling frequencySampling is the process of converting the heights ofsound wave (analog signal) samples taken at setperiods into digits (digital encoding). Samplingfrequency is the number of samples taken persecond, so larger numbers mean more faithfulreproduction of the original sound.Signal QualityThis is the guide for checking the aerial direction. Thenumbered values displayed do not indicate thestrength of the signal, but the quality of the signal (thesignal to noise ratio, or “S/N”). The channels you canreceive are affected by weather conditions, seasons,time (day/night), region, length of the cable that isconnected to the aerial, etc.ThumbnailThis refers to a miniature representation of a pictureused to display multiple pictures in the form of a list.x.v.Colour TMx.v.ColourTM is a name for devices that are compatiblewith the xvYCC format, an international standard forexpanded colour in motion pictures, and that followthe rules for signal transmission.You can enjoy vivid colours of wider colour ranges fora more realistic picture when connected to a TV thatsupports the x.v.ColourTM with HDMI cable.1080iIn one High Definition image, 1080 (1125) alternatingscan lines pass every 1/50th of a second to create aninterlace image. Because 1080i (1125i) more thandoubles current TV broadcasts of 480i (525i), thedetail is much clearer and creates a more realisticand rich image.1080pIn one High Definition image, 1080 (1125) scan linespass at the same time every 1/50 th of a second tocreate a progressive image. Since progressive videodoes not alternate scan lines like interlace, there is aminimal amount of screen flicker.24pThis is a progressive image recorded at a rate of 24frames per second.720pIn one High Definition image, 720 (750) scan linespass at the same time every 1/50 th of a second tocreate a progressive image. Since progressive videodoes not alternate scan lines like interlace, there is aminimal amount of screen flicker.Pan & Scan: The sides are cut off sothe picture fills the screen.Letterbox: Black bands appear at thetop and bottom of thepicture so the picture itselfappears in an aspect ratioof 16:9.
