Saib cable, satellite, DVD lossis VCR cov peev txheej ntawm koj lub PC hauv tsev nrog qee qhov yooj yim rau nruab PC kho vajtse. Kab lus no tham txog cov cim siv hauv Asmeskas (NTSC & ATSC), tab sis tuaj yeem siv hauv lwm lub tebchaws nrog kho vajtse tsim nyog. Thov nyeem kom tiav ua ntej yuav khoom.
Cov kauj ruam
Kauj Ruam 1. Txiav txim siab kho vajtse PC uas twb muaj lawm
Txiav txim siab yog tias tsis tau siv Kev Kub Ceev (2.0) USB chaw nres nkoj. Qhib lub khoos phis tawj (tom qab kaw) thiab tshawb xyuas qhov tsis nthuav dav nthuav dav thiab hom. Feem ntau hom kev tso rau hauv PCs niaj hnub no yog PCI thiab PCI Express. Qhov tsis siv AGP qhov yuav tsis haum. Siv daim duab hauv qab no los pab txheeb xyuas qhov qhib. Nyem rau ntawm ib daim duab kom pom dav.
Kauj Ruam 2. Txheeb xyuas qhov tam sim no tso tawm ntawm cable lossis satellite teeb lub npov saum toj
Yog tias siv cov kab hluav taws xob lossis cov hloov hluav taws xob los muab cov cim TV, tshuaj xyuas sab nraum qab ntawm cov cuab yeej no. Yuav muaj peev xwm yuav muaj ntau qhov tso tawm los ntawm qhov uas yuav xaiv. Siv daim duab los pab txheeb xyuas cov jacks hauv qab no:
- Coaxial lossis RF - Qhov no muab cov xov ib leeg nkaus xwb uas ib txwm ua rau 480i Txuj Kev Txhais (SDTV) video thiab suab (mono) teeb liab hauv TV channel 3 lossis 4. Lub jack no zoo li yog siv los txuas cable los ntawm cov tais lossis cov tuam txhab cable mus rau lub npov saum txheej.
- Kev sib xyaw - Qhov no yog ib lub nkaus daj thiab tuaj yeem tso tawm SDTV lub teeb liab video nkaus xwb.
- S -Video - Qhov tso tawm nkaus nkaus nkaus xwb no muab cov cim video ntawm qhov zoo me ntsis zoo dua li coaxial thiab sib xyaw.
- Cheeb Tsam - Qhov no yog qhov liab, ntsuab thiab xiav tso tawm ntawm 480i SDTV thiab 480p EDTV (Kev Txhais Lus Txhais), 720p, 1080i thiab 1080p HDTV (Kev Txhais Siab) video nkaus xwb.
- HDMI - Qhov nkaus nkaus nkaus xwb muab kev daws teeb meem ntawm SDTV los ntawm HDTV cov duab video thiab cov suab zoo digital (txawm tias tsis yog Dolby Digital 5.1 cov cim) hauv ib kab.
Kauj Ruam 3. Nrhiav NTSC (lossis tshiab dua, ATSC) Tuner / Capture card (hu ua "daim npav tuner" rau tom ntej)
Tau txais daim npav tuner nrog qhov sib txuam (a) qhov sib txuas (PCI lossis PCI Express) thiab (b) sib txuam cov teeb liab / hom txuas rau lub cable lossis satellite tso tawm / hom jack.
Kauj Ruam 4. Siv USB tuner yog tias tsis muaj qhov qhib lossis nws xav kom tsis txhob nkag mus rau hauv rooj plaub PC
Tsis saib xyuas qhov sib piv ntawm lub qhov yog tias siv USB interface. Tsuas yog lub coaxial nkaus (lossis RF) suav nrog ob qho tib si suab thiab yees duab hla tib lub xov tooj (lub HDMI nkaus yuav dhau ob qho tib si suab thiab yees duab ib yam, tab sis raws li kev sau ntawv no, tsis muaj daim npav tuner muaj cov tswv yim HDMI). Hauv txhua qhov xwm txheej, cais cov kab hluav taws xob yuav tsum tau kho los ntawm lub thawv sab saum toj rau hauv PC daim npav suab (lossis tuner yog tias muaj). Qhov no yog ua tiav los ntawm kev txuas lub npov sab saum toj lub xim liab & dawb (muab sab laug & sab xis tso suab tso suab) rau hauv lub khoos phis tawj suab, lossis txuas nrog SPDIF nkaus (ob qho tib si fiber optic lossis qauv qauv) yog tias teeb tsa ntawm ob lub npov saum lub npov thiab lub computer. Kev txuas nrog SPDIF yuav muab 5.1 Dolby Digital lub suab tawm yuav tsum siv yog tias lub khoos phis tawj muaj ntau dua li ob tus neeg hais lus xwb, txwv tsis pub cov xov tooj cua pheej yig yuav ua haujlwm zoo ib yam. Tam sim no, daim npav tuner txhawb nqa ib lossis ntau qhov coaxial, sib xyaw thiab s-video jacks. Ib daim npav NTSC pheej yig yog txhua yam uas xav tau rau ib qho ntawm cov kev npaj piav qhia saum toj no. Daim npav tuner tsis txwv kom tau txais tsuas yog kab lossis xov tooj cua teeb tsa lub npov saum toj tshaj plaws - txhua qhov sib xws thiab qhov sib txuas ua ke tuaj yeem txuas nrog xws li VCR, DVD, Lub Koob Yees Duab, thiab lwm yam, nrog cov khoom sib txuas
Kauj Ruam 5. Xav txog daim npav ATSC yog tias koj muaj peev xwm tau txais cov tshaj tawm digital ntawm tus kav hlau txais xov los ntawm tus tshaj xov xwm digital TV
ATSC cov khoos phis tawj yog tus qauv TV tshiab hauv Asmeskas tom qab Lub Ob Hlis 2009, thaum cov teeb liab TV sib piv tau teem tseg. Laus, NTSC daim npav npav yuav dhau los ua tus nqi pheej yig raws li cov khw muag khoom sim tshem lawv cov txee ntawm cov khoom qub. Tab sis, feem ntau ATSC daim npav xa rov qab tau zoo dua rau NTSC, thiab yuav tso cai saib qhov tshiab, digital (thiab HDTV) cov cim. Yog tias nruab nrog qhov tsim nyog jacks, nws yuav tso cai nkag los ntawm ib qho ntawm lwm qhov chaw teeb liab tau teev tseg saum toj no. ATSC tuner txuas nrog USB yuav tsum tsis txuas nrog cov laus, qeeb dua "Full Speed" (version 1.1) USB chaw nres nkoj. Kev Kub Ceev (version 2.0) cov chaw nres nkoj txuas ncaj qha rau lub motherboard lossis daim npav nthuav dav yog qhov zoo tshaj (tsis txhob siv ntau lub chaw nres nkoj).
Kauj Ruam 6. Nruab lub tuner kho vajtse thiab software hauv PC
Nruab raws li qhov chaw tsim khoom cov lus qhia kom ua tiav kev teeb tsa.
Kauj Ruam 7. Txuas lwm qhov chaw ntxiv rau daim npav tuner raws li xav tau
Lub tswv yim
- Txuag daim ntawv muag khoom! Saib HDTV cov cim yuav tsum muaj kev sib xyaw ua ke ntawm cov muaj zog niaj hnub microprocessor thiab daim npav duab sib cuam tshuam. Yog tias tsis muaj lub zog txaus, qhov zoo yuav raug kev txom nyem. Choppy, blotchy, thiab lwm yam vis dis aus thiab hais lus tsis meej yog qhov qhia tau ib txwm muaj. Qee zaum, kev kho dua tshiab tuaj yeem daws qhov teeb meem - qee zaum nws yuav xav tau kho dua ob qho los yog lwm yam yuav tsis raug nqi thiab xa daim npav tuner yuav yog txoj hauv kev mus.
- SPDIF (tshaj tawm "spid-if") sawv rau "Sony Philips Digital Interface." Sony thiab Philips yog ob lub tuam txhab uas tsim cov txheej txheem. Nws muaj nyob rau hauv ob qho tib si kho qhov muag thiab coaxial yam. Tsis txhob yuam kev coaxial SPDIF cables nrog coaxial RF cable TV hom cable. SPDIF cables kuj qee zaum hu ua AC3 thiab TOSLINK ib yam.
