Ndezvipi zvikwereti izvi uye zvikwangwani zvandakatarisana ini dzimwe nguva ndinoona paTV yangu skrini?
Apo patinotarisa purogiramu kana mafirimu paTVV kana kuti mavhidhiyo ekuratidzira, tinoda kuona mifananidzo yakachena isina kuvhiringidzika, uye pasina zvigadzirwa. Zvinosuruvarisa, pane zviitiko zvechokwadi izvo izvozvo hazviti kuitika. Zvimwe zvisingadiwi, asi zvinowanzoonekwa, zvigadzirwa zvaunogona kuona paTV yako kana kuratidzwa kwechinyorwa mumaitiro ekuona ndeye Macroblocking uye Pixelation.
Icho Macroblocking Ndicho
Macroblocking ivhidhiyo inoshandiswa pane zvinhu kana zvikamu zvemufananidzo wevhidhiyo inoita seyakagadzirwa nezvikwereti zviduku, panzvimbo pane zvakanyatsorondedzerwa uye zvakashata. Zviratidzo zvinogona kuonekwa mumufananidzo wose, kana muzvikamu zvemufananidzo. Zvinokonzera macroblocking zvakabatana nechimwe kana zvimwe zvezvinhu izvi zvinotevera: video compression , data transfer transfer, kupesana kwechiratidzo uye kushandiswa kwemavhidhiyo kuita.
Apo Macroblocking Inonyanya Kuonekwa
Macroblocking inonyanya kuoneka pamakambani, sataneti, uye kushandiswa kwepainternet semasipirwo ezvo dzimwe nguva dzimwe nguva dzinoshandisa kuwandisa kwevhidhiyo yakawanda kuitira kuti dzifambise mimwe nzira mukati mehutano hwavo hwunharaunda.
Macroblocking inogonawo kuitika, kusvika pamwero muduku, munguva yepamusoro-in-inoparadzirwa neTV. Migumisiro yaro inonyanya kuonekwa muzvirongwa zvepurogiramu nezvizhinji zvekufamba (yebhola ibasa rinowanzoitwa) sezvo izvo zvinoda mamwe mavhidhiyo evhidhiyo kuti aende kune imwe nguva.
Chimwe chikonzero chinogona kukonzera macroblocking ndiko kupindira kwepakati pekuparidzira, kambo kana kadhi rekushambadzira. Kana izvi zvikaitika, unogona kuona mufananidzo wechinguvana uchiratidzwa paTV kana mujekesi yakagadzirwa nezvikwereti uye zvigadziko zvakanyatsodzika kana zviso.
Macroblocking inogonawo kuva mugumisiro wemavhidhiyo mavhidhiyo uye / kana upscaling nedhidhiyo kana kutaridza. Nemuenzaniso, kana iwe une upscaling DVD player iyo isingagoni kushandura uye kuwedzera upiyo mavhidhiyo kubva pane zvakajeka kusvika kuH HD chisarudzo zvakaringana, unogona kuona mamwe mamiriro emitambo ye macroblocking, zvakare, zvichida panguva yezviitiko zvine maitiro akawanda kana panning mamiriro. Macroblocking inogona kuonekwawo paTV, Maketheni / Matambo eStaneti (kunyanya mumitambo yemitambo) apo chirevo chacho chinokurumidzira uye uye uye zvimwe zviratidzo zvekutambira kana TV yako haigoni kuchengeta. Uyewo, kana internet yako inokurumidza isingakurumidzi zvakakwana , iyo inogonawo kukonzera nyaya dze macroblocking nekushambadzira kwezvinhu.
Pixelation
Macroblocking inowanzonziwo pixelation, uye kunyange zvazvo yakafanana, pixelation iri shoma shoma, imwe nhanho-nhanho yemigumisiro iyo dzimwe nguva inowanikwa pamakona ezvinhu maererano nechemberi, kana mukati mukati maro, semakumbo pamusoro kana mumuviri. Pixelation inopa zvinhu maitiro akaoma. Zvichienderana nekugadzirisa kwechifananidzo, ukuru hwekona kana kuti uri pedyo zvakadini kana iwe uri kure kubva pachigadziko, zvinokonzerwa nepikelelation zvingave zvisinganyatsooneki.
Nzira yakanakisisa yekunzwisisa pixelation ndeyekutora mufananidzo uchishandisa kamera kana foni yedijitori uye uione pane yePc monitor yako kana laptop. Zvadaro wozorora mukati kana kuputira hukuru hwechifananidzo. Kana iwe ukanyanya kuvhara kana kuputira chifananidzo, rugher chifananidzo chichatarisa, uye iwe uchatanga kuona mitsetse yakare uye kurasikirwa kwemashoko. Pakupedzisira, iwe uchatanga kuona kuti zvinhu zviduku uye nemiganhu yezvinhu zvikuru zvinotanga kutarisa sezvikamu zviduku.
Macroblocking uye Pixelation paDheji dzeDVD
Imwe nzira iyo iwe ungasangana nayo macroblocking uye / kana pixelation iri pamabhuku ekudhikirira DVD . Kana DVD yako rekodhi (kana kuti PC-DVD munyori) isina dhi rakakwana yekunyora nokukurumidza kana iwe ukasarudza mabhuku 4, 6, kana 8 (izvo zvinowedzera kuwanda kwekushandiswa kunoshandiswa) kuitira kuti uwane mamwe mavhidhiyo nguva pa disc , DVD rekodha inogona kunge isingakwanisi kubvuma kukosha kwekuona video yevhidhiyo.
Somugumisiro, unogona kuguma nemapuranga akadzikiswa mukati, mukati mekunyora uye kunyange nenguva dzinoshandiswa macroblocking. Muchiitiko ichi, sezvo mapurisa akadonherwa uye pixelation uye / kana macroblocking migumisiro inonyorwa yakanyorerwa padhidhi, hapanazve mamwe mavhidhiyo ekugadziridzwa akaitwa muDVD player kana TV anogona kuvabvisa.
The Bottom Line
Macroblocking uye Pixelation zvinhu zvinogona kuitika panguva yekuona vhidhiyo kubva pane zvakasiyana-siyana. Sezvo macroblocking uye pixelation zvingava mugumisiro weimwe yezvimwe zvinhu, zvisinei pasinei neTV munei, unogona kuve nemigumisiro pane dzimwe nguva.
Zvisinei, kuvandudzwa kwevideo compression codecs (yakadai seMpeg4 neH264 ) uye yakawanda yakanyatsogadziridzwa yevhidhiyo mapurogiramu uye upscalers dzakaderedza mitambo ye macroblocking uye pixelation mubhodhi iyo kubva pakuparidzira, kabheji nekushambadzira mazano, asi kuvhara kwechiratidzo dzimwe nguva hakugoneki.
Uyezve, zvinofanira kuonekwa kuti macroblocking uye pixelation inogonawo dzimwe nguva kugadzirwa nechinangwa chevakasika kana vaparidzi, sezvinenge apo zviso zvevanhu, mapepa emakisi emotokari, zvikamu zvemuviri wega kana zvimwewo zivo inozivikanwa zvinonzwisiswa nechinangwa chemugadziri wezvinhu kubva pakuonekwa nevaterevhizi veTV.
Izvi dzimwe nguva zvinowanikwa mumashumo eTV, zviitiko zvemitambo zveTV, nezvimwe zviitiko zvemitambo umo vanhu vangave vasina kupa mvumo yekushandisa mufananidzo wavo, kudzivirira vatengesi vakasungwa kuti vasati vazivikanwa panguva yekumusungwa kana kudzima mazita emakadhi akaiswa kune tee-shirts kana hats.
Zvisinei, kungoshandisa kushandiswa zvine chinangwa, Macroblocking uye Pixelation zviri pachena zvinhu zvisina kunaka zvausingadi kuona paTV.
