Ngosizo lwesiteshi se-IP-network yekhompyutha, ukusakazwa kwevidiyo kwezinhlelo zethelevishini kuyenziwa. Futhi, izinsizakalo zokuvakashela ngebhokisi le-set-top ye-SML-282 zingashintsha i-TV evamile ibe i-Smart TV. Ngobuchwepheshe besimanje be-IPTV, isekethe yephrosesa ye-elekthronikhi yamadekhoda aqukethwe kuma-set-top box e-SML-282 ikhetha isiteshi sikamabonakude. Ukuboniswa kwesignali yevidiyo nokusakaza okulalelwayo kuyenzeka kumadivayisi ahlukahlukene axhunywe ngezindawo zokusebenzelana ezinezintambo.

Siyini isiqalo se-Smartlabs SML-282 Base, siyini isici saso

I-Smartlabs yethula amadivayisi e-IPTV – amabhokisi abekwe phezulu i-SML-282 HD Base. Amadivayisi afanayo nawo akhiqizwa ngophawu lokuhweba lomhlinzeki i-Rostelecom SML-282. Isici sobuchwepheshe be-IP futhi ngesikhathi esifanayo inzuzo yayo yindlela yokuxhumana yezindlela ezimbili, evezwa ikhono lokulawula iseva. Umsebenzisi angavakashela umtapo wolwazi futhi enze isicelo sevidiyo. Kumapulatifomu ethulwe, ngaphezu kokuqukethwe kwamahhala, kukhona nokuqukethwe okukhokhelwayo. I-set-top box ye-SML 282 HD ikuvumela ukuthi ubuke amavidiyo ekhwalithi ephezulu enezici ezilandelayo:

• phumuza ukudlala;
• hlehlisa ividiyo nganoma iyiphi indlela;
• buka inkomba yohlelo lwe-TV bese wenza isicelo sokubuka ukusakazwa kwevidiyo ngakunye.
• ukubukela izinhlelo ze-TV ezirekhodiwe kuze kufike emahoreni angu-48;
• ukuvakashela indawo yesibikezelo sezulu;
• ukufinyelela ezinsizeni ze-inthanethi, njengezinkundla zokuxhumana, i-imeyili, i-YouTube, nezinye eziningi;
• i-cinema eku-inthanethi;
• ukushintsha ukubuka amavidiyo, izithombe nezithombe kusuka kudrayivu yangaphandle ngembobo ye-USB.

Ukufinyelela i-inthanethi kuyenzeka ngokuxhuma kumzila ngembobo ye-Ethernet. Amanye amadivaysi, njengekhompyutha ephathekayo, angaxhumeka kumodemu futhi kamuva axhumane ne-set-top box ngesixhumi esibonakalayo esingenantambo se-Wi-Fi. Izinsizakalo ze-IPTV zinikezwa umhlinzeki ngokuya ngezindleko ezimisiwe. Isilawuli kude se-SML 282 sisebenza njengomxhumanisi womsebenzi wedivayisi esebenzisanayo. Inesilawuli kude esibonakalayo sebhokisi lokusetha eliphezulu le-STB.

Imininingwane, ukubukeka

Ibhokisi lesethi-phezulu lesignali ye-IPTV lenziwa kukesi lepulasitiki elinohlangothi lwesikwele oluyi-150 mm nobude obungu-55 mm. Uhlangothi lwangaphambili oluwunxande luqukethe inkomba yesimo kanye ne-photosensor yesilawuli kude. Iphaneli engemuva ephambene iqukethe izixhumi zokuxhuma amadivayisi. Isilawuli kude sisebenzisa amabhethri angu-2 AAA. Inkinobho yokusetha kabusha isistimu kuzilungiselelo zasembonini itholakala ohlangothini lukanxande. Ivikelwe ekucindezeleni ngephutha ohlangothini lwepulasitiki lwephaneli enembobo encane ye-pusher, ongayenza ngayo inkinobho. I-SML 282 inezici ezilandelayo:

• Iphrosesa – STi7105;
• Inkumbulo yokusebenza – 256 MB, ROM (Flash) – 128 MB;
• Ubukhulu bokulungiswa kwevidiyo ngu-1080p, ngesilinganiso sozimele esingu-60 fps;
• Isekela amakhodekhi avamile omsindo nevidiyo asetshenziswa abahlinzeki;
• Amandla kagesi kagesi +12 V, ukusetshenziswa kwamanje 1.2 A.

Izimbobo zesixhumi esibonakalayo

I-set-top box ye-SML 282 isebenzisa izimbobo ezilandelayo zamashaneli okuxhumana anezintambo:

• Isixhumi se-RJ45 – imbobo ye-LAN (Ethernet);
• Imbobo ye-Optical S/PDIF;
• I-USB 2.0;
• I-HDMI;
• Izixhumi ze-RCA 6 ama-pcs (umsindo, i-stereo – ama-2 ama-pcs.), (ividiyo ye-RGB – ama-3 ama-pcs.), (ividiyo ye-CVBS – 1 ama-pcs.);
• Ipulaki yamandla.

Izisetshenziswa

I-accessory kit ihlanganisa:

• Idivayisi ye-SML 282;
• Isilawuli kude esinezici ze-2 AAA;
• I-adaptha yamandla AC/DC +12V;
• Ikhebula le-HDMI, 3xRCA, 5xRCA, Ethernet;
• Ukufundiswa ngesiRashiya, ukupakisha.

Uxhumano nokusetha

Okokuqala udinga ukuxhuma ibhokisi le-set-top ku-TV yakho noma imonitha. Ukuze wenze lokhu, kuye ngemodeli ye-TV, kuhlongozwa ukuthi kusetshenziswe enye yezinketho ezi-3:

1. I-HDMI – izixhumi ze-set-top box kanye ne-TV zixhunywe ngekhebula;
2. 3xRCA – 2 okuphumayo komsindo (okubomvu nokumhlophe noma okumnyama), ividiyo engu-1 (ephuzi);
3. 5xRCA – 2 stereo audio kanye 3 ividiyo (RGB).

Ixhuma futhi imisa ibhokisi le-set-top ye-Sml 282 hd[/caption] Uma uxhumeke kahle futhi imodi ehambisanayo yenziwa isebenze ku-TV, ikhwalithi ephezulu. Isikrini se-splash kufanele sivele esikrinini. Okulandelayo, xhuma i-inthanethi ngesixhumi se-LAN kumzila. Lapho begunyaza, basebenzisa ukungena ngemvume nephasiwedi abayithola kumhlinzeki lapho bephetha inkontileka.

Setha ngokuya nge-algorithm evela emiyalweni, lapho-ke uzodinga ukufaka ikhodi yedivayisi ngayinye yenethiwekhi. Ikheli le-MAC liboniswa kuphaneli ye-console. Ingaphinde itholakale esigabeni esithi “Ulwazi Lwesistimu” ngemuva kokuthi isistimu ivuliwe futhi iqaliswe.
 Ukusetha isilawuli kude se-SML 282 kwenziwa ngokwemiyalelo. I-DU evela kubahlinzeki abahlukene iyahluka.

I-firmware esemthethweni nehlukile ye-Smartlabs SML 282 HD Base

Ngeke kwenzeke ukushintsha isofthiwe ku-Smartlabs SML 282 HD Base usebenzisa isixhumi esibonakalayo sokulawula esiveziwe. Isistimu ngokwayo icela ukubuyekezwa futhi, uma inguqulo entsha itholakala, iyabuyekezwa. Kodwa-ke, ibhodi lesifunda eliphrintiwe ledivayisi liqukethe ichweba le-RS-232, lapho uhlelo lwe-microcontroller lungakhanyiswa khona esikhungweni sesevisi. Ngale njongo, imishini ehambisanayo nesofthiwe efanele iyadingeka. [i-id yamagama-ncazo = “okunamathiselwe_6717” align = “aligncenter” wide = “579”]
PCB Sml 282 hd[/caption] Sicela wazi ukuthi imiyalelo ye-firmware ayikwazi ukutholakala emhlabeni wonke. Kuhlobo ngalunye lwedivayisi kune-algorithm yomuntu siqu. Inqubo ye-firmware ayikwazi ukuphazanyiswa, ngaphandle kwalokho idivayisi ngeke isebenze. I-firmware yebhokisi le-set-top ye-Rostelecom i-SML 282 inephakheji yesevisi evele ilungisiwe evela kumhlinzeki. I-Smartlabs SML 282 HD Base set-top box iqukethe i-firmware ekwazi ukuxhuma ku-MTS, Rostelecom noma abanye opharetha. Kukhona ama-SML 282 HD Base consoles aqukethe enye i-firmware. Ngesofthiwe enjalo, kungenzeka ukukhetha umhlinzeki. Zenzele ngokwakho enye i-firmware yebhokisi le-Rostelecom set-top Sml 282 – imiyalo yevidiyo: https://youtu.be/I7QNTJ_Chcw

Ukupholisa ibhokisi le-set-top

Ukusebenza kwephrosesa yedivayisi yokucubungula isignali ye-IPTV kubangela ukuthi i-chip chip okufakwe kuyo isipholile somoya ukuthi ishise. Ngakho-ke, ngesikhathi sokusebenza komkhiqizo, kuyadingeka ukuthi umzimba wokunamathiselwe ube nokufinyelela mahhala emoyeni, awugoqiwe futhi umoya awuvaliwe.

Izinkinga ngesikhathi sokusebenza kanye nesixazululo sabo

Ngesikhathi sokusebenza kwe-set-top box, ukwehluleka namaphutha kungenzeka. Ukuze uxazulule izinkinga ngokubukeka kwazo, kufanele uqale uvale idivayisi futhi uvumele isikhathi sokuthi i-microprocessor chip yomkhiqizo iphole. Uma ngemuva kokuqala kabusha ukwehluleka kunganyamalala, khona-ke:

1. Kudingekile ukuhlola ukunemba kokuxhumeka kanye nokuthembeka koxhumana nabo kuma-interfaces anezintambo;
2. Yenza ukusetha kabusha kwefekthri futhi ulungise kabusha idivayisi.

Uma izinsiza ezihlinzekwa umhlinzeki zinganeliseki noma umsebenzisi enquma ukwandisa inani lamashaneli noma engeza ezinye izici, khona-ke ukuxazulula izinkinga ezinjalo, bashintsha isofthiwe. Ngesikhathi esifanayo, enye i-firmware ye-android ifakiwe ku-SML282 HD Base, isibonelo. Kufanele futhi kuqashelwe ukuthi ukushintsha uhlelo akuqinisekisi ukusebenza kwedivayisi ngenani elinikezwe umenzi wezinto zokusebenza.

Ubuhle nobubi

I-Smartlabs SML 282 HD Base inokufinyelela kuzinsiza zedijithali zamaseva. Inganikwa amandla ngentambo ye-fiber optic noma i-Ethernet enentambo. Inzuzo yayo enkulu ukusebenzisana – amandla okuphatha okuqukethwe ngokudlala kwekhwalithi ephezulu. Ububi bamadivaysi anjalo ukuncika komnikazi wocingo kumnikezeli wesevisi kanye nemali yokubhalisa. Kodwa umsebenzisi unikezwa amathuba abanzi edivayisi enokugcinwa kuyimfihlo okuphezulu. Amabhokisi okusetha phezulu njenge-SML-282 anamandla okuguqula cishe noma iyiphi, ngisho neyakudala, i-TV ibe i-Smart TV. Umshini oshibhile ungenza imisebenzi eminingi enobuchwepheshe bekhompyutha kuphela.
