115RQT9439ReferenceLPCM (Linear PCM)These are uncompressed digital signals, similar to those found onCDs.MPEG2 (Moving Picture Experts Group)A standard for efficiently compressing and expanding colour video.MPEG2 is a compression standard used for DVD and satellite baseddigital broadcasting.MPEG-4 AVC/H.264A standard for efficiently compressing and expanding colour video.MPEG-4 AVC/H.264 is an encoding method used for recording ofthe high definition videos.MP3 (MPEG Audio Layer 3)An audio compression method that compresses audio toapproximately one tenth of its size without any considerable loss ofaudio quality.Pan&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.Progressive/InterlaceInterlace is a conventional image signal that displays the image in 2phases by splitting the display into odd and even scans.Progressive will display whole image in 1 scan. Therefore, it will givehigh definition image without flickering compared with interlace.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.RouterDistinguishes the IP address assigned to each device, such as thePC, and relays the flow of data within the network.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.Signal QualityThis is the guide for checking the aerial direction. The numberedvalues displayed do not indicate the strength of the signal, but thequality of the signal (the signal to noise ratio, or “S/N”). The channelsyou can receive are affected by weather conditions, seasons, time(day/night), region, length of the cable that is connected to the aerial,etc.Subnet maskEnables efficient network use. A set of numbers which identify whichpart of the IP address allocated to every device connected to therouter is the network portion.ThumbnailThis refers to a miniature representation of a picture used to displaymultiple pictures in the form of a list.TransponderThe signals of a broadcasting station are received by a transponderon a satellite. The transponder converts them to frequencies andsends them to satellite dishes near the ground. A transponder canbroadcast several TV and radio programmes or data in parallel.x.v.Colour TMx.v.ColourTM is a name for devices that are compatible with thexvYCC format, an international standard for expanded colour inmotion pictures, and that follow the rules for signal transmission.You can enjoy vivid colours of wider colour ranges for a morerealistic picture when connected to a TV that supports thex.v.ColourTM with HDMI cable.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.
