Ibibazo byo gutangaza tereviziyo ya digitale: kuki imiyoboro idakora, nta kimenyetso, hariho kwivanga

Nubwo ibimenyetso bihagaze neza, ishusho nziza cyane nijwi mugihe cyo gutangaza tereviziyo ya digitale, ingorane rimwe na rimwe zivuka mugihe cyo gutangaza televiziyo. Ni muri urwo rwego, imiyoboro ya tereviziyo ya digitale ntishobora kuboneka kandi ntigaragaza. Birakenewe gusobanukirwa ibitera ikibazo no kugikemura.

Niki wakora niba nta kimenyetso cya tereviziyo ya digitale niki gitera ikibazo

Mbere yuko utangira gukemura ikibazo, ugomba kumenya ishingiro ryacyo. Ikimenyetso cya TV cya digitale gishobora gucika kubwimpamvu zimwe:

• multiplex yahagaritse gutangaza ibimenyetso bya TV;
• gukora imirimo yo gusana;
• ingaruka z’ikirere;
• ibikoresho bidakwiye.

Ubwa mbere ugomba kumenya neza ko TV iherereye muri zone yakira ibimenyetso byizewe. Niba igikoresho cyerekanaga ishusho hanyuma kigahagarara, noneho antenne birashoboka cyane ko idahujwe neza . Niba ibikoresho byashyizweho aribyo bitera ikibazo, ugomba rero kumenya urwego rwohereza imiyoboro ya tereviziyo ya sisitemu: software cyangwa ibyuma. Mubyongeyeho, igenamiterere kuri TV rishobora kugenda nabi, nyuma yo guhagarika kwerekana.

Guhagarika ibiganiro kuri TV

Niba ibimenyetso bya tereviziyo ya digitale bidafashwe, ugomba kumenya neza ko nta kubungabunga ibidukikije. Urashobora kubimenya kurubuga rwa interineti, aho hagomba gucapurwa gahunda yo gukumira no gusana. Mugihe cyo gukora ikizamini, multiplex ya kabiri irazimya kandi amakuru akenewe arakusanywa, noneho gutangaza birahagarara rwose. Ubu mu turere twinshi tw’Uburusiya ni paki imwe gusa ikoreshwa mu gutangaza televiziyo.

Gusana akazi

Urashobora kumenya kubyerekeye imirimo yo gusana kurubuga rtrs.ru. Akenshi ibirori nkibi bikorwa kubera ibikoresho byangiritse kumunara wa TV biterwa nikirere kibi.

Ntabwo yerekana TV bitewe nikirere

Ikimenyetso cya tereviziyo idafite imbaraga nacyo gishobora guterwa nikirere kibi. Umuyaga mwinshi, imvura, inkuba bigira ingaruka kumiterere yo kwakira ibimenyetso. Muri iki kibazo, ubwiza bwishusho nijwi byangirika, ishusho igaragara mumirongo, cyangwa ntihashobora kuba ikimenyetso na kimwe.

Muri iki kibazo, ugomba kureba ibipimo byerekana urwego. Niba agaciro kabo kari hasi, bagomba kuzamurwa hejuru.

Ingaruka yimiterere yikirere ntishobora kuba impamvu yo gutakaza burundu imiyoboro ya tereviziyo. Ibi birashobora guca intege ibimenyetso gusa.

Ibyuma bibi

Niba amajwi ahindagurika, kandi ishusho ikaba idafite ubuziranenge, noneho birashoboka cyane ko ikibazo cyatewe nibikoresho bidakwiye. Gusenyuka birashobora kandi gutuma habaho ishusho yuzuye ya digitale. Amakosa arashobora kuba afitanye isano na:

1. Hamwe na antene . Ugomba kumenya neza ko antenne yerekejwe ku munara wa TV. Antenne yo mu nzu irananirwa cyane kurenza iyo hanze. Nkuko bisanzwe, imikorere mibi ibaho kubera inkuba, inkubi y’umuyaga cyangwa imvura. Kongera guhindura uwakiriye ntibishobora gutanga ibisubizo. Kugirango umenye ikosa no kugikosora, ugomba gukora intambwe zikurikira:
   • reba voltage mumashanyarazi;
   • reba umugozi n’amacomeka;
   • niba urebye ibikoresho bidakemura ikibazo, huza antene nshya.
2. Kumugereka . Nibyoroshye cyane gukemura ikibazo cyo hejuru-agasanduku. Iyo ifunguye, diode idasanzwe yaka itara ryijimye cyangwa ntirimurika na gato. Niba nta gikorwa kibaho mugihe ukanda buto kuva kure ya kure, noneho set-top box ni amakosa. Igomba guhindurwa mukindi no kugenzura itangwa rya signal ya digitale. Ibibazo bishoboka hamwe nibisobanuro:
   • Televiziyo ntishobora kuboneka kubera verisiyo ishaje yabakiriye , igomba gusimburwa nindi nshya.
   • Porogaramu idahwitse yububiko bwa set-top box irashobora kuba impamvu yo kubura ibimenyetso. Niba agasanduku-gashyizwe hejuru karashaje, ugomba gukuramo software nshya kurubuga rwemewe rwuwabikoze, hanyuma ukayivugurura. Kugirango ukore flashing nziza, nibyiza guhindukirira abanyamwuga.
   • Inyandiko ivuga ko nta kimenyetso gishobora kubaho bitewe no gusubiramo byihuse . Kugira ngo ukemure ikibazo, ugomba kumenya neza ko ibimenyetso bya TV byakiriwe neza kandi ugakora ubushakashatsi bushya kumiyoboro ya TV.

   Agasanduku gashyizwe hejuru gakeneye gusanwa niba:

   • nta cyerekanwa kuri ecran niba hari tulip ikora;
   • hari reboot yihitirwa mugihe runaka nyuma yimiterere ikozwe;
   • mugihe ushakisha imiyoboro ya TV, nta makuru yerekeye ubwiza bwikimenyetso cya TV mugihe antenne ihujwe.
3. Hamwe na kabili hamwe . Ibi bibazo nabyo bibaho kenshi. Igice kimwe, umugozi uherereye kumuhanda, kubwibyo, hamwe no gukoresha igihe kirekire, guhinduranya birasenywa kandi bigahanagurwa, ibice bigaragara. Birakenewe kumenya niba harabayeho kurenga ku busugire bwumugozi uwo ariwo wose. Niba ibyangiritse bibonetse, umugozi uzakenera gusimburwa.

Kuki Digital TV iterekana (cyangwa yerekana nabi) nicyo wakora niba imiyoboro idakora (nta kimenyetso): https://youtu.be/ZL5Qs_K4xvU

Ibibazo bishoboka kuki TV idafata imiyoboro ya digitale / idafata igice

Ibibazo byo kwerekana imiyoboro ya tereviziyo ya digitale birashobora kuba muburyo butandukanye. Reka tubitekerezeho birambuye.

Urutonde rwumuyoboro wose ntirwabonetse

Nyuma yo gushakisha mu buryo bwikora, ntabwo imiyoboro yose ya TV ishobora kuboneka. Birashoboka cyane ko uwakiriye atabonye paki ya kabiri, none bizaba ngombwa gushakisha imirongo yumunara wa TV wegereye cyane. Muri iki kibazo, urashobora kubona imiyoboro yose ukoresheje intoki. Akenshi impamvu ituma imiyoboro yose itaboneka irashobora kuba antenne ubwayo. Igomba gutoranywa ukurikije intera iri hagati yumunara mukarere runaka:

• niba umunara uri hagati ya 1-2 km, noneho antenne isanzwe yo murugo irashobora gukoreshwa;
• niba umunara uherereye muri radiyo ya kilometero 20-30, noneho hagomba gukoreshwa antene ifite ibimenyetso byongera ibimenyetso;
• intera ya 30-70 km, ugomba kugura antenne yo hanze hamwe na amplifier.

Nigute ushobora gukora antenne ya DVB-T2 kuri tereviziyo ya digitale ubwawe byasobanuwe mu ngingo ikurikira .

Gukoresha imbaraga nyinshi cyane amplifier bitari ngombwa birashobora gutuma ibimenyetso biteshwa agaciro.

Kuki uterekana TV yuzuye

Ibi birashobora guterwa no guhitamo amashusho atariyo cyangwa kudahindura TV kuri AV cyangwa HDMI. Ugomba kandi kugenzura niba prefix ishoboye . Ibi birashobora kumenyekana nurumuri rwerekana, rumurika icyatsi iyo rufunguye. Gufungura kuri set-top agasanduku, koresha igenzura rya kure cyangwa buto kuriyo.

Uwakiriye arahari, ariko nta kimenyetso cya TV cyerekana

Muri iki kibazo, birashoboka cyane ko antenne yaciwe cyangwa amplifier kuri yo. Ugomba kugenzura niba ihujwe, kuyikuramo no kuyishiramo inyuma, hanyuma usubiremo gushakisha byikora.

Byanditswe ko nta serivisi, kandi autosearch ntacyo ibona

Mugihe wakiriye ibimenyetso bidakomeye, gushakisha byikora bisiba imiyoboro ya tereviziyo, hamwe nubushakashatsi bwintoki kuri buri nshuro bizerekana imbaraga zikimenyetso gikomeye cyane.

Hano hari “freze”: ishusho igabanyamo kabiri

Ugomba kugenzura imbaraga zerekana ibimenyetso. Kugirango ukore ibi, kanda buto yamakuru kuri kure ya kure. Uku kugoreka kw’ishusho kugaragara kubera kuba kure cyane y’umunara cyangwa inyubako nini zibangamira iyakirwa rya televiziyo. Urashobora gukemura ikibazo wongereye ibimenyetso ukoresheje antenne ikora. Ku mbaraga nyinshi kandi zifite ubuziranenge, uzakenera gukora antenne. Urashobora kugerageza kuzana antenne hanze hanyuma ukagerageza gushaka ahantu heza (urugero, uzamure). Hamwe nubwiza buke nimbaraga, harakenewe kongera ibimenyetso.

Niba “freze” igaragara kenshi, ibi byerekana ikimenyetso kibi cyangwa impinduka mumiterere yikirere.

Kugaragaza nabi televiziyo ya digitale – ibimenyetso bibi nubuziranenge bwamashusho

Niba imbaraga z’ikimenyetso ari nyinshi kandi ubwiza bw’ishusho ntibwemerwe, antene izakenera guhinduka cyangwa gusimburwa. Igomba guhindurwa. Ubwanwa bufitanye isano na metero, kandi impeta ifitanye isano na decimeter. Nibyo bigomba kuzunguruka. Ugomba kubona ahantu heza kuri antenne – kuzenguruka icyumba hamwe nayo, jya mu idirishya. Urukuta rwa beto rwubatswe, idirishya rya plastike (amakadiri) rirashobora kubangamira itumanaho rya tereviziyo.

Ifoto itagaragara

Iki nikimwe mubibazo bikunze kugaragara mubakoresha TV. Kurugero, TV ifite diagonal ya santimetero 40 cyangwa zirenga irashobora kugira ishusho nziza, itagaragara. Ibipimo bisanzwe bya tereviziyo ya digitale bifata amajwi yerekana ishusho ya 720×576. Niba TV ifite diagonal nini, ishusho izaba itagaragara cyangwa pigiseli izagaragara. Kubakurikirana bafite diagonal, ibiganiro byiza bya TV birakenewe – urugero, HD (1280×720) na Full HD (1920×1080). Hariho inzira ebyiri zo gukosora ibintu:

1. Shira itegeko kumurongo wa HD yamashanyarazi hamwe nuwitanga serivisi . Kubitekerezaho ishusho isobanutse kandi nziza kuri ecran hamwe na diagonal nini, iyi niyo nzira nziza.
2. Koresha TV ishaje ifite diagonal nto . Nubwo hari aho bigarukira, ishusho izaba yujuje ubuziranenge.

Kugaragara kwa glare (shelegi) kuri ecran

Ibibazo nkibi birashoboka nubwo ureba televiziyo. Ibi birashobora kubaho kubera insinga ihuza STB cyangwa imashini yakira TV. Kugira ngo ukemure ikibazo, ugomba gukoresha urundi rugozi.

Hano harakonje, ishusho irasenyuka

Muri iki kibazo, nibyiza kuvugana nubufasha bwa tekiniki bwabatanga serivise kugirango abanyamwuga biga abiyandikisha cyangwa ibikoresho bya sitasiyo bakamenya inkomoko yikibazo. Nkesha amabwiriza aboneka, biroroshye kumenya impamvu ituma tereviziyo ya digitale iterekana kandi ikayikuraho. Niba ibikorwa byose byakozwe bitatsinzwe, urashobora rero kugisha inama kubuntu kubigo byunganira tekinike mukarere kawe hanyuma ugahamagara abashinzwe umwuga murugo rwawe.
