High-bandwidth Digital Content Protection yog qhov kev nyab xeeb tsim los ntawm Intel Corporation uas yuav tsum tau siv HDCP-certified cov khoom kom tau txais HDCP-encrypted digital teeb liab.
Nws ua haujlwm los ntawm kev nkag mus rau lub teeb liab digital nrog tus yuam sij uas yuav tsum muaj kev lees paub los ntawm ob qho tib si xa thiab txais cov khoom. Yog tias kev lees paub tsis raug, lub teeb liab tsis ua haujlwm.
Lub Hom Phiaj ntawm HDCP
Lub Digital Content Protection LLC, Intel lub koom haum pabcuam uas tso cai HDCP, piav qhia nws lub hom phiaj raws li daim ntawv tso cai thev naus laus zis los tiv thaiv cov yeeb yaj kiab uas muaj txiaj ntsig zoo, TV yeeb yaj kiab, thiab suab los ntawm kev nkag tsis tau lossis luam tawm. Kev siv HDCP-raws li cables thiab cov khoom siv los xa cov ntaub ntawv HDCP-encoded, hauv txoj kev xav, yog tsim los txwv tsis pub luam tawm lossis rov sau dua ntawm cov xov xwm encrypted los ntawm cov khoom siv tsis tau tso cai.
Muab qhov sib txawv: Ntau xyoo dhau los, tib neeg yuav ob lub tshuab kaw video, tom qab ntawd muab hlua khi ua ke. Koj yuav ntaus VHS daim kab xev, tab sis lub teeb liab los ntawm VCR ntawd pub rau VCR thib ob nrog daim kab xev dawb los sau. Qhov thib ob VCR ces pub rau TV, kom koj tuaj yeem saib thiab luam cov yeeb yaj kiab ib txhij yam tsis muaj teeb meem lossis nrhiav pom. Kev siv cov khoom siv HDCP thiab cov cables tam sim no txwv tsis pub tus cwj pwm no tshwj tsis yog tias koj ua cov kauj ruam txawv txawv kom tau lossis hloov kho cov khoom siv kom tshem tawm HDCP encoding los ntawm kwj.

Lub DCP tau tso cai ntau pua lub tuam txhab ua cov neeg siv HDCP.
Yuav ua li cas daws teeb meem kev sib txuas HDMI
Txuas HDCP
HDCP yog qhov cuam tshuam thaum koj siv digital HDMI lossis DVI cable. Yog tias txhua yam khoom siv cov cables txhawb HDCP, ces koj yuav tsum tsis txhob ntsib teeb meem. HDCP yog tsim los tiv thaiv tub sab ntawm cov ntsiab lus digital, uas yog lwm txoj hauv kev hais tias tsis raug kaw. Raws li qhov tshwm sim, HDCP tus qauv txwv ntau npaum li cas koj tuaj yeem txuas tau. Cov neeg feem coob yuav tsis mloog, tab sis qee qhov kev siv (piv txwv li, pub lub txhab nyiaj ntawm TVs ntawm qhov chaw ua si) muaj teeb meem tam sim no.
Yog tias tag nrho cov khoom siv yog HDCP-certified, tus neeg siv khoom yuav tsis pom dab tsi. Qhov teeb meem tshwm sim thaum ib qho ntawm cov khoom tsis yog HDCP-certified. Ib qho tseem ceeb ntawm HDCP yog tias nws tsis tas yuav tsum tau los ntawm txoj cai lij choj kom sib haum nrog txhua qhov kev sib tshuam. Nws yog kev yeem tso cai kev sib raug zoo ntawm DCP thiab ntau lub tuam txhab.
Tseem, nws yog qhov poob siab rau cov neeg siv khoom uas txuas Blu-duab tshav disc player rau HDTV nrog HDMI cable tsuas yog pom tsis muaj teeb liab. Kev daws rau qhov teeb meem no yog siv cov khoom siv cables tsis yog HDMI lossis hloov lub TV. Qhov ntawd tsis yog qhov kev pom zoo feem ntau cov neeg siv khoom xav tias lawv pom zoo thaum lawv yuav HDTV uas tsis yog HDCP tau ntawv tso cai.
HDCP khoom
Cov khoom lag luam nrog HDCP poob rau hauv peb lub thoob-qhov chaw, dab dej, thiab rov ua dua:
- Ntaus yog cov khoom lag luam uas HDCP teeb liab pib. Lawv yog A point hauv A-rau-B-rau-C kev txiav txim ntawm cov xwm txheej. Cov khoom lag luam hauv pawg no suav nrog DVRs, cov thawv teeb tsa, cov xov tooj digital, Blu-duab tshav player, thiab DVD recorders.
- Sinks yog cov khoom lag luam uas tau txais HDCP teeb liab thiab tso rau qhov chaw. Lawv yog C point hauv A-rau-B-rau-C kev txiav txim ntawm cov xwm txheej. Cov khoom lag luam hauv pawg no suav nrog TVs thiab digital projectors.
- Repeaters yog cov khoom uas tau txais HDCP teeb liab los ntawm qhov chaw thiab xa mus rau lub dab dej. Lawv yog B point hauv A-rau-B-rau-C ntawm cov xwm txheej. Cov khoom lag luam hauv pawg no suav nrog cov khoom siv rov ua dua, cov sib cais, hloov pauv, AV receivers, thiab wireless transmitters.
Rau cov neeg siv khoom xav paub uas xav tshawb xyuas seb cov khoom puas muaj HDCP, DCP tshaj tawm cov npe ntawm cov khoom pom zoo ntawm nws lub vev xaib.
kab hauv qab
Tsis muaj kev hloov kho firmware tuaj yeem hloov qhov tsis yog HDCP cov tswv yim rau hauv HDCP-raws li ib qho. Yog tias koj nyuam qhuav yuav HDTV, koj yuav tau txais HDCP yuam kev thaum txuas Blu-duab tshav disc player rau koj lub TV ntawm HDMI cable.

HDMI yog dab tsi?
HDCP yog cov thev naus laus zis nkaus xwb uas tso siab rau DVI thiab HDMI cables. Tias yog vim li cas koj yuav pom cov lus luv luv xws li DVI / HDCP thiab HDMI / HDCP. HDMI stands rau High-Definition Multimedia Interface. Nws yog ib qho digital interface uas tso cai rau koj HDTV los ua qhov zoo tshaj plaws uas tsis muaj duab digital ua tau. HDMI muaj kev txhawb nqa zoo heev los ntawm kev lag luam duab. Qee qhov hnyav hnyav hauv kev lag luam khoom siv hluav taws xob xws li Hitachi, Matsushita, Philips, Silicon Image, Sony, Thomson, thiab Toshiba tau pab tsim nws.
DVI yog dab tsi?
Tsim los ntawm Pawg Ua Haujlwm Digital, DVI sawv cev rau Digital Visual Interface. Nws yog qhov qub digital interface uas muaj tag nrho tab sis tau hloov los ntawm HDMI hauv TV. Muaj ob qhov txiaj ntsig tseem ceeb ntawm HDMI dhau DVI:
- HDMI xa lub suab thiab video teeb liab hauv ib lub cable. DVI tsuas yog hloov cov vis dis aus, yog li yuav tsum muaj ib lub xov tooj sib cais.
- HDMI nrawm dua DVI.
HDCP HDTV Kev Qhia Txog Kev Yuav
Ntau lub TV uas nyuam qhuav tsim tawm yog HDCP raws; Txawm li cas los xij, yog tias koj yuav cov khoom qub, koj yuav tsis tuaj yeem saib cov yeeb yaj kiab, ua si, lossis saib Netflix. Txawm hais tias koj lub HDTV siv HDMI lossis DVI, xyuas kom tseeb tias nws muaj tsawg kawg ib qho kev tawm tswv yim nrog HDCP kev txhawb nqa ua ntej yuav khoom.
