Zvisinei, sechinhu chisingadikanwi chinogadzirisa, kune vakawanda vatengi vari kutarisa zvirongwa zveterevhizheni zvekare uye VHS yekare pamaVHTV avo matsva. Izvi zvakakonzera kunyunyuta kwakawanda pamusoro pehutano hwakasvibiswa hwehufananidzo hwemifananidzo yeterevhizhi yemasvivhoni uye mavhidhiyo eanalogog paanoonekwa pane HDTV.
HDTV: Ha & # 39; t Nguva dzose Tarisa Zviri nani
Iko pfungwa huru yekuita kuti kudumbuka kubva kune analogo kusvika kuHDTV ndeyokuwana unhu huri nani hwekutarisa ruzivo. Zvisinei, kuva neHDTV hakusi kugadzirisa zvinhu nguva dzose, kunyanya kana uchitarisa zvinhu zvisinganzwisisiki zveAn HD.
Zvechokwadi, mavhidhiyo eAnalogog, akadai seVHS uye analog cable, muzviitiko zvakawanda, anotarisa zvakanyanya pane HDTV kupfuura zvavanoita pamutambo wakafanana weterevhizheni.
Chikonzero chezviitiko izvi ndezvekuti HDTVs ine simba rokuratidza zvakawanda zvakanyanya kupfuura TV yeAnalogo, iyo yaunowanzofunga kuti chinhu chakanaka-uye, chikuru, chikamu chikuru. Zvisinei, iyo itsva HDTV haisi kuita kuti zvinhu zvose zvionekwe zviri nani sezvo vhidhiyo inogadzirisa zvikwata ( iyo inogonesa chinonzi chinonzi video upscaling ) inowedzera zvikamu zvakanaka uye zvakaipa zvemufananidzo wakagadziriswa.
Iyo yakachena uye yakanyatsogadzikana chiratidzo chepakutanga, chikonzero chakanaka chaunenge uine. Zvisinei, kana mufananidzo wacho une ruvara rwemumusasa wepamusera, kupindira kwechiratidzo, kubuda kwemavara, kana zvinetso zvepamusoro, (izvo zvingave zvisingaoneki paTanalog TV nekuda kwekuti iri kukanganwira nekuda kwekugadzirisa kwakadzika) video inoshandiswa mune HDTV achaedza kuichenesa. Zvisinei, izvi zvinogona kutumira mhinduro yakavhenganiswa.
Chimwe chinhu chinoita kuti huterevhizheni yeAnalogog iratidze paHDTV inofanirwawo nevhidhiyo upscaling inoshandiswa nevanoita mavhidhiyo akasiyana-siyana. Dzimwe HDTV dzinoita kutendeuka kweanalog-to-digital uye upscaling process kupfuura vamwe. Kana uchitarisa maTVV kana kuti maongororwo eHDTV, nyora zvinyorwa zvese maererano nevhidhiyo upscaling quality.
