Mapaketi a audio ndi video amaphatikizidwa ndi ma markers a nthawi kuti set-top box ikhoza kusewera kuchokera kulikonse m'madzi, popanda index ndi popanda kusungira fayilo yonse. Chithunzicho ndichifukwa chake MPG zolemba zimasewera pa zida zakale mosasamala kanthu komanso zimasokoneza mapulogalamu amakono nthawi zonse. Zina mwa zinthuzi ndi MPEG-1 kapena MPEG-2 kanema ndi MP2 audio; muxing ndi GOP chilengedwe ndi ofanana ndi.mpeg fayilo.
Nchifukwa chiyani pulogalamu yofalitsa ndi yolemba ima insist pa MPG?

Chifukwa cha zonse mzere anapangidwa pa izo. Playout ma seva, DVD authoring zipangizo ndi ingest machitidwe anafotokozedwa m'munsimu format pamene izo zinali zatsopano, ndi zida ndi zaka makumi awiri ntchito moyo si anapeza re-anafotokozedwa. Fayilo kutuluka mwa iwo machitidwe ndi format dongosolo anapangidwa kuti emit, si kusankha aliyense anachita posachedwapa. MPG ndi kuwonjezeka DVD authoring mapulogalamu, older camcorders ndi kufalitsa ingest zipangizo kuzindikira, kotero kuti imakhala zothandiza kwa iwo ma pipelines.
Kodi MPG ndi mtundu umodzi monga momwe zimakhalira?
+
Yes.
Nchifukwa chiyani msakatuli wanga sadzasewera fayilo ya MPG?

Mawebusayiti amatumiza decoders kwa mndandanda wocheperako wa mafomu, ndipo MPG siyipatsidwa - lisensi, mtundu wa codec womwe umalola, kapena nthawi yake imatenga. Fayilo siyimawonongeka ndipo wosewera wa desktop adzatsegula, koma palibe chomwe mungachite patsambalo kuti mupange msakatuli. Kusintha kwa webusaitiyi ndi njira yokha yotsimikizika yosewera. MPG amalandira zonse MPEG-2 kuletsa - heavy bitrate, interlacing, palibe soft subtitle - kuphatikizapo kusokonezeka kwa awiri zowonjezera kwa mtundu wina.
Kodi MPG idzasewera pafoni kapena TV popanda kutulutsa batri?

Nthawi zambiri ndi choncho, chifukwa ma chips mu mafoni, ma tablet ndi ma televisions amachotsa ma code a ma payloads amtunduwu m’ma silicon osankhidwa osati pa main processor. Izi ndi zosiyana pakati pa kanema womwe umasewera bwino kwa maola awiri ndi wina amene umatentha chipangizocho ndipo umachisiya m’maola asanu ndi awiri. Pamene mtunduwo umagwa pansi ndi kuthandizira kwa app kuposa kuchotsa ma code – codec ndi bwino, wrapper ndi zomwe gallery app ingakane.
