Digital terevhizheni inogamuchira – chii ichocho, kusarudza uye kugadzirisa

Kubva pakati pa2019, kutepfenyura kweterevhizheni muRussia kwachinja kudhijitari fomati. Iye zvino, kuti vaone zvirongwa zvavo zveTV zvavanofarira, vashandisi vanofanira kubatanidza mimwe michina kuTV – inogamuchira digital. Ngationei kuti rudzii rwechigadzirwa chacho, chii chinoshanda, uye kuti mutengi angasarudza sei inogamuchira modhi inoenderana naye maererano nekushanda, mhando uye mutengo.

Chii chinonzi digital TV inogamuchira

Inogamuchira (kana set-top box) mudziyo unogamuchira chiratidzo chedhijitari, woiisa muchimiro chinonzwisiswa neTV uye unotaridza mufananidzo paTV skrini, uye ruzha pane masipika akabatana nawo. Nayo, unogona kuona dhijitari TV yemafomati akasiyana – tambo , satellite kana terrestrial .. Kune set-yepamusoro mabhokisi anogona kushanda nemhando dzinoverengeka dzezviratidzo. Nzira yekusarudza satellite receiver, chii chekutsvaga: https://youtu.be/hNLHLOA0-Ks Ichi hachisi nguva dzose chiri chekunze. Mazhinji maTV, kunyanya mamodheru azvino anoburitswa mushure megore ra2012, ane anogamuchira atovakwa mukesi. Kazhinji aya ndiwo akareruka mamodheru anotendera iwe kuti utarise makumi maviri enhepfenyuro chiteshi chemubatanidzwa. Asi kune zvakare maTV ane yakavakirwa-mukati tambo uye setiraiti inogamuchira.

Zviya! Iwe unogona kuona kana iyo TV seti ine yakavakirwa-mukati inogamuchira kubva kune mirairo yekushanda kwayo kana tsananguro yehunhu muchitoro chendaneti. Kana zvinyorwa zvine chikamu “Digital chiratidzo chetsigiro” kana chidimbu cheDVB-T2, saka TV inozokwanisa kugamuchira chiteshi chemhepo pasina kubatanidza mimwe michina.

Kuwedzera kushanda kwevanogamuchira

Signal reception uye decoding ndiwo mabasa makuru emuterevhizheni anogamuchira. Asi, mukuwedzera kwavari, mhando dzemazuva ano dzemidziyo iyi dzakashongedzerwa dzakasiyana siyana dzekuwedzera sarudzo dzinowedzera kuve nyore kwekushandisa digital TV:

1. Air management . Inokutendera kuti umbomira kutepfenyura, uye mushure mechinguva ramba uchiona kubva kwawakasiira.
2. Yakanonoka Nhepfenyuro . Zvinoita kuti zvikwanisike kuronga kurekodhwa kwechirongwa cheTV chinodiwa mundangariro yebhokisi repamusoro-soro kuitira kuti uzvione gare gare. Panguva imwecheteyo, kurekodha kunoitwa pasina kupindira kwemushandisi uye hazvidi kuvhura TV. Iwe unongoda kupa mudziyo kuraira pachine nguva, uye inozotanga kunyora nhepfenyuro panguva yakakodzera pachayo.
3. Teletext . Inopa mushandisi mukana weiyo inopindirana chirongwa chegwaro.
4. Subtitles uye sarudzo yemutauro wenhepfenyuro . Inokutendera kuti utarise zviteshi zvekunze neshanduro dzenguva imwe chete muzvinyorwa kana zvekuteerera. Zvinyaradzo zvemazuva ano zvinotsigira zvinyorwa zvishoma mumitauro yakati wandei.
5. Wi-Fi module . Inokutendera kuti ugadzirise kutarisa kwedhijitari chiteshi kwete paTV chete, asiwo pamalaptops epamba, makomputa uye mahwendefa.
6. RF-OUT . Vanogamuchira vanowedzerwa neichi chinongedzo vanopa vashandisi mukana wekuona kwete chete dhijitari , asiwo analog chiteshi (kana iripo). Mumatunhu mazhinji, makambani emuno eTV achiri kuenderera mberi nekutepfenyura mune analogue fomati.
7. Indaneti . Nesarudzo iyi, mushandisi achakwanisa kuwana masocial network, mawebhusaiti emabhaisikopo epamhepo uye masevhisi evhidhiyo, kutamba mitambo yepamhepo, nezvimwe kubva paTV.

Zvakakosha! Nevakagadzirirwa-mukati vanogamuchira, kuwedzera kushanda kunowanzova kushoma. Mhando dzekunze chete dzinogona kuzvirumbidza dzakasiyana siyana dzekuwedzera sarudzo.

Vazhinji vekuRussia vanogashira dhijitari TV masevhisi kuburikidza nemupi. Izvi zvinoita kuti zvikwanise, mukuwedzera kune emahara chiteshi chemubatanidzwa, kuona nzira dzakabhadharwa dzeakasiyana siyana eRussia uye ekunze makambani eterevhizheni. Vanopa, semutemo, vanopa vashandisi vane avo vanogashira vakashongedzerwa nechiratidzo encryption uye kunyoresa mvumo masisitimu. Zvishandiso zvevashandisi vakasiyana hazvienderane kune mumwe nemumwe, kureva, semuenzaniso, kutarisa Tricolor-TV chiteshi kuburikidza neiyo Rostelecom prefix haishande.

Mhando dzevanogamuchira

Vagamuchiri veTV vanosiyana kwete chete muchimiro chechimiro (yemukati nekunze). Kune mamwe akawanda classifications:

• nemutengo wemhando;
• nemhando yekubatanidza (kuwanika kwezvibatanidza zve tulip cable, USB kana HDMI cable);
• kune seti yedzimwe sarudzo.

Asi iyo huru inogona kunzi kupatsanurwa maererano nenhepfenyuro inotsigirwa nemudziyo. Parizvino, kune matatu akakosha zviyero uye, maererano, mapoka matatu makuru emabhokisi-yepamusoro mabhokisi:

• DVB-S (S2, S2X) – satellite kutepfenyura, inogamuchira inobatanidzwa kune satellite dish yakaiswa pane facade kana padenga reimba, kana pane zvivakwa zviri pedyo;
• DVB-C (C2) – tambo yekutepfenyura, iyo set-yepamusoro bhokisi yakabatana nemidziyo yemupi ine fiber optic tambo;
• DVB-T2 – kutepfenyura, iyo inogamuchira yakabatana kune yakajairika imba kana yemukati antenna, iyo inogamuchira chiratidzo kubva kune shongwe yeTV.

Iyo DVB-T2 fomati inokubvumira kuti ugamuchire chete mahara-kumhepo chiteshi, uye kazhinji haigone kupa inogamuchirika nhepfenyuro mhando (munzvimbo dziri kure neTV shongwe). Mafomati maviri asara anoita kuti zvikwanise kuona mamwe machaneti, asi zvinoda kupera kwechibvumirano nemupi uye kubhadharwa kwenguva dzose yemubhadharo wekunyoresa.

Zvakakosha! Pane chikamu chechina chevanogamuchira – vakasanganiswa. Vanokwanisa kugamuchira zvikwangwani mune akati wandei mafomati kamwechete, semuenzaniso, pamhepo uye satellite kutepfenyura.

Nzira yekusarudza anogamuchira, chii chekutarisa

Paunenge uchironga yekubatanidza terevhizheni yedhijitari , iwe unofanirwa kutanga wafunga kuti mushandisi achave nematanho epasi akakwana here, kana kuti zvakakosha kubatana kune chero mupi kuti agamuchire zvimwe zvirimo. Muchiitiko chekutanga, zvichave zvakakwana kutenga yakapusa yekugamuchira modhi yakagadzirirwa chete kugamuchira DVB-T2 masaini. Iyi isarudzo yakanaka yekugara kwezhizha, imba yekurenda zuva nezuva, uye dzimwe nzvimbo dzekugara kwenguva pfupi.

Zviya! Rondedzero yezviteshi zvepamhepo inovandudzwa gore rega rega, zvinoenderana nemhedzisiro yemakwikwi akavhurika umo makambani akasiyana eterevhizheni anotora chikamu. Uye munguva pfupi nyika inoronga kuwedzera iyo kubva pamakumi maviri kusvika makumi matatu zvidimbu.

Kana iwe ukaronga kubatanidza kune masevhisi evanopa TV, unogona kutora nzira yekushomeka kushomeka uye kutenga kubva kwavari imwe yemaseti-yepamusoro mabhokisi anokurudzirwa navo.
