    en.wikipedia.org › wiki › 576i

    576i is a standard-definition video mode originally used for terrestrial television in most countries of the world where the utility frequency for electric power distribution is 50 Hz. Because of its close association with the colour encoding system, it is often referred to as simply PAL , PAL/ SECAM or SECAM when compared to its 60 Hz ...

    When 576i video is trans­mit­ted via base­band (i.e., via con­sumer de­vice ca­bles, not via RF), most of the dif­fer­ences be­tween the "one-let­ter" sys­temsare no longer sig­nif­i­cant, other than ver­ti­cal res­o­lu­tion and frame rate. In this con­text, un­qual­i­fied 576iin­vari­ably means 1. 625 lines per frame, of which 576 carry picture content 2. 25 frames per second interlaced yielding 50 fields per second 3. Two interlaced video fields per frame 4. With PAL or SECAMcolor (4.43 MHz or 3.58 MHz (576i-N & 576i-NC)) 5. frequency-modulated or amplitude-modulatedaudio (mono) 6. Mono or stereo audio, if sent via connector cables between devices

    576i when it is trans­mit­ted over free-to-air satel­litesig­nals is trans­mit­ted sub­stan­tially dif­fer­ently from ter­res­trial trans­mis­sion. Full transpon­der mode (e.g., 72 MHz) 1. Luma signal is frequency-modulated (FM), but with a 50 Hz ditheringsignal to spread out energy over the transponder 2. Chroma is phase-modulated (PM) 3. An FM subcarrier of 4.50, 5.50, 6.0, 6.50 or 6.65 MHz is added for mono sound 4. Other FM subcarriers (usually 7.02, 7.20, 7.38, 7.56, 7.74 and 7.92 MHz) are added for a true-stereo service and can also carry multi-lingual sound and radio services. These additional subcarriers are normally narrower bandwidth than the main mono subcarrier and are companded using Panda 1 or similar to preserve the signal-to-noise ratio. 5. Data subcarriers may also be added Half-transpon­der mode (e.g., 36 MHz) 1. All of the above is done, but signal is bandwidth-limited to 18 MHz 2. The bandwidth limiting does not affect audio subcarriers

    When 576i is used to trans­mit con­tent that was orig­i­nally com­posed of 25 full pro­gres­sive frames per sec­ond, the odd field of the frame is trans­mit­ted first. This is the op­po­site of NTSC. Sys­tems which re­cover pro­gres­sive frames, or transcode video should en­sure that this field order is obeyed, oth­er­wise the re­cov­ered frame will con­sist of a field from one frame and a field from an ad­ja­cent frame, re­sult­ing in 'comb' in­ter­lac­ing ar­ti­facts.

    Mo­tion pic­tures are typ­i­cally shot on film at 24 frames per sec­ond. When telecined and played back at PAL's stan­dard of 25 frames per sec­ond, films run about 4% faster. This also ap­plies to most TV se­ries that are shot on film or dig­i­tal 24p. Un­like NTSC's telecine sys­tem, which uses 3:2 pull downto con­vert the 24 frames per sec­ond to the 30 fps frame rate, PAL speed-up re­sults in the telecined video run­ning 4% shorter than the orig­i­nal film as well as the equiv­a­lent NTSC telecined video. De­pend­ing on the sound sys­tem in use, it also slightly in­creases the pitch of the sound­track by 70.67 cents (0.7067 of a semi­tone). More re­cently, dig­i­tal con­ver­sion meth­ods have used al­go­rithms which pre­serve the orig­i­nal pitch of the sound­track, al­though the frame rate con­ver­sion still re­sults in faster play­back. Con­ver­sion meth­ods exist that can con­vert 24 frames per sec­ond video to 25 frames per sec­ond with no speed in­crease, how­ever image qua...

    Phase Alternating Line ( PAL) is a colour encoding system for analogue television used in broadcast television systems in most countries broadcasting at 625-line / 50 field (25 frame) per second ( 576i ). It was one of three major analogue colour television standards, the others being NTSC and SECAM .

  11. 576i or 480p, what is better when viewed on HDTV? | NeoGAF

    www.neogaf.com › threads › 576i-or-480p-what-is

    576i is only a higher resolution if the game is running at 25fps, if it's running at 50 then it's going to be equivalent to 288p. 576i will also suffer from motion artefacts, whereas 480p won't. With the Wii, most games seem to have the flicker-filter enabled when you use an interlaced setting, completely blurring all the detail out of the game.
