Järgmises NTSC standardis, mis töötati välja <a href="/wiki/1953" title="1953">1953</a>. aastal, oli värvitelevisiooni edastus standardiseeritud ja lisaks oli see tagasiühilduv juba kasutuses olevate must-valge televisiooni vastuvõtuseadmetega. </p><p>USA Föderaalse Sidekomisjoni FCC loodud Riiklik Televisioonistandardite Komitee andis 1941. aastal välja esimese versiooni must-valge analoogtelevisiooni edastamiseks. Võeti kasutusele 525 horisontaalset rida. NTSC standardiseeris kaadrisageduseks 30 täiskaadrit sekundis. Üks täiskaader koosneb kahest poolkaadrist (262,5 rida) ehk siis kuvatakse 60 poolkaadrit sekundis. Lisaks määrati kuvasuhteks 4:3 ja helisignaali ülekandmiseks kasutati sagedusmodulatsiooni, mis oli siis üsna uus tehnoloogiline saavutus. </p><p>1950. aasta jaanuaris hakkas komitee normeerima värvitelevisiooni edastamist ja <a href="/wiki/1953" title="1953">1953</a>. aasta detsembris kiideti üksmeelselt heaks uus NTSC värvitelevisiooni standard. Uus värvitelevisiooni standard oli täielikult tagasiühilduv juba turul eksisteerinud must-valge televisiooni vastuvõtjatega. Must-valge pildi värviliseks tegemiseks lisati signaalile värvikandesagedus 3,58 MHz. </p><p>Esimene avalik NTSC standardit kasutav värviline telepilt saadeti eetrisse <a href="/wiki/30._august" title="30. august">30. augustil</a> 1953, olgugi et see oli jälgitav värviliselt ainult sidevõrkude enda peakorteris.

Samal aastal tuli müüki TK-41, mida kasutati edukalt peaaegu 1960. aastateni. </p> <div class="mw-heading mw-heading2"><h2 id="Tehnilised_andmed">Tehnilised andmed</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=NTSC&veaction=edit&section=2" title="Muuda alaosa "Tehnilised andmed"" class="mw-editsection-visualeditor"><span>muuda</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=NTSC&action=edit&section=2" title="Muuda alaosa "Tehnilised andmed" lähteteksti"><span>muuda lähteteksti</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Read_ja_kaadrisagedus">Read ja kaadrisagedus</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=NTSC&veaction=edit&section=3" title="Muuda alaosa "Read ja kaadrisagedus"" class="mw-editsection-visualeditor"><span>muuda</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=NTSC&action=edit&section=3" title="Muuda alaosa "Read ja kaadrisagedus" lähteteksti"><span>muuda lähteteksti</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>NTSC kasutab värvi kodeerimisel süsteemi, kus üks kaader koosneb kahest poolkaadrist. Poolkaadri suuruseks on 262,5 rida. Täiskaadri edastuskiiruseks on 29,97 Hz. Iga kaader koosneb 525 reast, millest 480 sisaldab pildi infot. Ülejäänud ridu kasutatakse elektronkiire viimiseks diagonaalselt kaadri lõpust tagasi uue kaadri algusesse. Lisaks kasutatakse neid ridu ka teleteksti ning vertikaalse ajaintervalli info edastuseks. </p><p>Poolkaadrid saadakse ülerealaotuse teel, mis tähendab seda, et paarisarvulised read kantakse ekraanile esimese poolkaadri jooksul ning paaritud teise poolkaadri jooksul. Ühe poolkaadri sageduseks on 59,94 Hz (60 Hz/1,001). Võrdluseks: süsteemides PAL ja SECAM kasutatakse 625 rida 576 pildi ülekandmiseks ning poolkaadri sageduseks on 50 Hz. </p><p>Algselt oli kaadrisagedus seotud Ameerika Ühendriikides kasutatava 60 Hz võrgupingega, et vältida võimalikke võrgumürahäireid. Pärast värvi lisamist NTSC signaalile vähendati kaadrisagedus väärtuseni 59,94 Hz selleks, et kõrvaldada häired, mis tekkisid helikandesageduse ja värvikandesageduse ristmodulatsiooni tagajärjel. </p><p>Ridade arvu määramisel võeti arvesse nii silma maksimaalne nägemisteravus kui ka ülekandeks vajamineva sagedusspektri laius. Optimaalseks tulemuseks leiti, et rohkem kui 572 rea ülekandmisel ei ole enam mõtet. Arvestati, et silma nägemisteravus on 1 nurgaminut (1/60 kraadi) ning kodus asuks televiisor kuuekordse ekraani kõrguse kaugusel vaatajast. Neid andmeid kasutades saadigi, et 572 rea puhul silm ei suuda enam ridu teineteisest eristada.<sup id="cite_ref-Poulin_3-0" class="reference"><a href="#cite_note-Poulin-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Värvipildi_moodustamine"><span id="V.C3.A4rvipildi_moodustamine"></span>Värvipildi moodustamine</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=NTSC&veaction=edit&section=4" title="Muuda alaosa "Värvipildi moodustamine"" class="mw-editsection-visualeditor"><span>muuda</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=NTSC&action=edit&section=4" title="Muuda alaosa "Värvipildi moodustamine" lähteteksti"><span>muuda lähteteksti</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>NTSC kasutab pildi edastuseks kolme signaalikomponenti. Esimeseks ning ka kõige olulisemaks on pildipunkti heleduse ülekandmine (heleduse tähis on Y). Heledussignaal on ka ainuke pildi edastuse komponent must-valges televisioonis. Teised kaks pildiedastuse komponenti on I ja Q (<i>In-phase</i> ja <i>Quadrature-phase</i>), millega määratakse antud punkti värvitoon. Kuna juba aastaks 1953 oli toodetud hulgaliselt must-valgeid televiisoreid, siis oli vajalik värvitelevisioon teha tagasiühilduvaks juba turul olevate televisiooniseadmetega. See tähendas, et must-valge televiisoriga oli võimalik vaadata ka värvitelevisiooni saateid (muidugi must-valgelt). </p><p>NTSC värvitelevisiooni ülekandel kasutatakse <a href="/wiki/Kvadratuur-amplituudmodulatsioon" title="Kvadratuur-amplituudmodulatsioon">kvadratuur-amplituudmodulatsiooni</a>, kus värvisignaalikomponendid I ja Q edastatakse kandesagedusel 3,579545 MHz omavahel 90-kraadise <a href="/wiki/Faas" title="Faas">faasinihkega</a>. Signaalid I ja Q annavad pildipunktidele värvi ning amplituudmoduleeritud signaal Y annab punktile heleduse. Värviinfo on paigutatud väikeste fragmentidena, nn etalonsignaalidena reasünkroimpulsi algusesse. Etalonsignaal koosneb vähemalt kaheksast võnkeperioodist ning on jäetud moduleerimata, see tähendab, et signaal peab olema faasi- ja amplituudikindel. Võrreldes etalonsignaali vastuvõetud <a href="/wiki/Videosignaal" title="Videosignaal">videosignaaliga</a>, saadakse faasierinevused, millega määratakse värvitoon, ning amplituudi erinevustega tehakse kindlaks antud punkti heledus. </p> <figure typeof="mw:File/Thumb"><a href="/wiki/Fail:Ntsc_channel.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/f/fd/Ntsc_channel.svg/300px-Ntsc_channel.svg.png" decoding="async" width="300" height="183" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/f/fd/Ntsc_channel.svg/450px-Ntsc_channel.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/f/fd/Ntsc_channel.svg/600px-Ntsc_channel.svg.png 2x" data-file-width="306" data-file-height="187" /></a><figcaption>NTSC signaali sageduspekter: <br /><b>luma carrier</b> – kujutisesignaali kandesagedus <br /> <b>chrome carrier</b> – värvisignaali abikandesagedus <br /> <b>audio carrier</b> – helisignaali kandesagedus</figcaption></figure> <div class="mw-heading mw-heading3"><h3 id="Televisioonisignaali_spekter">Televisioonisignaali spekter</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=NTSC&veaction=edit&section=5" title="Muuda alaosa "Televisioonisignaali spekter"" class="mw-editsection-visualeditor"><span>muuda</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=NTSC&action=edit&section=5" title="Muuda alaosa "Televisioonisignaali spekter" lähteteksti"><span>muuda lähteteksti</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>NTSC televisiooni ühe kanali <a href="/wiki/Ribalaius" title="Ribalaius">ribalaius</a> on tervikuna 6 MHz.
