Ko MPG te ōrite o te MPEG-1, MPEG-2 rānei te ataata ki te.mpeg, ko te whakaroa anake o te whakaroa o te pūmanawa DOS-era e hiahiatia ana.

MPG Ngā Pātai Auau mō te Tahuritanga
He aha te MPG?
+
MPG (MPEG) is a family of standards for coding audio-visual information.
He aha te rerenga papatono MPEG, ā, he aha te take o te mea ko ahau?
+
He maha te hanga hei whakakōrerotia e ngā pūrere taumahi pūmau i te wā tūturu, kāore e taea te whakahōu i runga i tētahi rorohiko. Ko ngā pakipū oro me te ataata e whakawāteatia ana me ngā tohu wā kia tīmata ai te tākaro i tētahi tāruatanga-tūtū i tētahi wāhi i roto i te rerenga, me te kore pūtautau me te kore e whakawātea i te faila katoa. Ko te take o taua hoahoa ko te take o te MPG ihirangi e tākaro ana i ngā pūrere tawhito, ā, ka whakawātea i ngā pūmanawa o nāianei. Ko ngā ihirangi he MPEG-1, he MPEG-2 rānei te ataata me te oro MP2; he ōrite te whakakotahitanga me te hanganga GOP ki tētahi pūranga.mpeg.
He aha te pūmanawa pāohotanga me te tuhituhi e whakahau ana ki MPG?
+
Nā te mea i hangaia te mekameka katoa ki runga i a ia. Ko ngā pūnaha whakapāpāho, ngā utauta tuhi DVD me ngā pūnaha whakawhanake i whakapūtātia i te taha o tēnei āhua i te wā o tēnei wā, ā, kāore e whakapūtātia anō ngā pūrere me te wā o te ratonga whai hua e rua tekau tau. Ko ngā pūranga e puta mai ana i ēnei pūnaha ko te āhua o te pūnaha i hangaia hei tuku, ehara i te kōwhiringa i hangaia e tētahi tangata i tēnei wā. Ko MPG te whakaroanga o te pūmanawa tuhituhi DVD, e mōhiotia ana e ngā kāmera tawhito me ngā utauta whakateretanga pāohotanga, nā reira ka noho whai hua tonu mō ēnei pūtautau.
He ōrite te āhua o MPG ki ōna whakaroatanga atu?
+
He. Ko tēnei whakaroanga me te ingoa roa, poto rānei e kitea ana e koe i te taha o te whakaahua i tētahi āhua taketake, ā, ko tētahi mea e whakaako ana, e whakaako ana rānei i te rua. He hītori nga ingoa e rua: he tepe ingoa pūranga e waru ngā āhua mai i te wā DOS, he kaipāpāho e whakaingoa ana i tōna taupānga i te āhua o tōna pūranga, e rua rānei ngā papatono i whakaritea kētia. Ka whakaputa anō te tahuritanga i te hua ōrite, nō reira ka whakamahia te whakaroanga e tūmanako ana te pūmanawa i te taha o te taha.
He aha te take kāore e whakatangitangi te mātāwai i tētahi MPG?
+
Ko ngā kaiwhaiwhai e whakarewa ana i ngā whakakōrero mō tētahi rārangi poto o ngā āhuahira, ā, kāore te MPG i runga i te — te āhuahira, te momo codec e whakaaetia ana, e noho tonu ana tōna pakeke. Kāore te faila i te whakaroa, ā, ka whakatuwheratia e te kaiwhakaari papamuri, engari kāore he mea e mahi ana koe ki te pātaka ka whakawātea e te kaiwhaiwhai. Ko te tahuri ki tētahi tahuri tīpaetia-tīwae te huarahi anake e tautoko ana i te whakateretanga. Ka tukua e MPG ngā whakawhāiti katoa o MPEG-2 — te mokatere bit taumaha, te whakawhāititanga, kāore he whakarārangi māmā — tae atu ki te whakawāteatanga o ngā whakaroatanga e rua mō tētahi hanga.
He aha te take i whakaaturia ai e ahau MPG ngā raina kākahu i runga i tētahi mea e neke ana?
+
Nā te mea kua whakawhāititia. Ko ngā ihirangi i tēnei pūāhua i te nuinga o te wā e puta mai ana i te wā o te whakataka me te DVD, i reira ka rokirokitia ia tākaro hei āpure haurua-tūtū e rua i tangohia he rima tekau o te tuarua. Ka whakaaturia e te whakaata ā-whakahaere i te wā kotahi, kia puta ai te nekehanga i waenganui i ngā whakaaturanga e rua hei whakawhāiti whakapae. Ka whakarerekētia te tahuritanga i runga i te tahuritanga i ngā āpure ki ngā tātuhi katoa, ā, ka ngaro te taonga mō te pai. Ko te MPG te rerenga papatono MPEG ōrite ki te.mpeg — ko te whakaroatanga tuhipoka e toru he whakaroatanga o te wā DOS, ehara i te hanga rerekē.
Ka whakapāpāho te MPG ki runga i tētahi pūkoro, TV rānei me te kore e whakawātea i te pūkoro?
+
I te nuinga o te wā, ā, nā te mea ko ngā pūrere i roto i ngā tāuru, ngā tātari me ngā pouaka whakaata e whakawaehere ana i tēnei momo utu i roto i ngā pūrere kua whakaritea, kaua i te pūnaha matua. Ko te rerekētanga i waenganui i tētahi ataata e whakaata ana i te rua wā me tētahi e whakamārō ana i te pūrere, ā, ka whakawātea i roto i te whā tekau minu. I te wāhi e whakapeka ana te āhua, he tautoko papatono, ehara i te whakawaeheretanga — he pai te pūrere, ko te whāriki te mea e whakakāhore ana te papatono whare whakataki.
Me tiaki tonu ahau i ngā pūranga hōu hei MPG?
+
Ahakoa rā, mēnā e hiahiatia ana e tētahi mea ki raro iho. Ka tuwhera tonu te āhua, ā, kāore he tūpatotanga mō te tahuri i tētahi pūranga kāore e take ana i ngā raruraru, engari kāore anō kia haere te utauta, te tōtika rānei. Mō tētahi mea hōu, kāore he utu tāpiri o te āhua o nāianei, ā, ka ārai i te porowhita o tēnei pātai i ētahi tau mai i tēnei wā.
He aha te wāhi e haere ai ngā whakarārangi mō tētahi MPG pūranga?
+
I te taha o ia, ki roto rānei i te whakaahua. MPG kāore he rerenga whakahuatuhi o tōna ake, nō reira ko ngā kōwhiringa e rua he.srt file te kaipāpāho e whakarewa ana i te taha o te ataata, te whakawhānui rānei i te kupu ki roto i ngā tātuhi i te wā o te whakawaenga anō. Ka pupuri te kaipāho i ngā whakahuatuhi, ka taea hoki te whakawhiti, engari ka haere hei pūranga tuarua ngāwari ki te ngaro; Ka ora te whakawhanake i ētahi whakawhitinga, engari kāore e taea te whakakore i muri mai.
He mea hira rānei he toru tekau tau te MPG?
+
Ko te pakeketanga anake ehara i te raruraru — he maha ngā āhuahira mai i taua wā e pai tonu ana, i te mea kua tekau tau te whakatinana i a rātou. Ko te mea e hiahiatia ana ko te wā: he pūranga iti, he pūkaha iti, kāore he whatunga, me ngā āhuatanga kāore e hiahiatia ana e tētahi. Ki te āhua tonu o ēnei whakaaro, he pai te āhuahira. Ki te kore rātau, ko te take ki te tahuri.
Ka taea e tētahi MPG te pupuri i ētahi rererangi oro?
+
He — ka taea e tētahi whākōkī reo taketake, he tāruatanga me tētahi kōrero te noho katoa i roto i te pūrākau ōrite me te kaipāpāho e whakawhiti ana i waenganui i a rātou. E rua ngā mōrearea: he maha ngā pūpāho tāruatanga me te pouaka whakaata e whakaatu ana i te pūrākau tuatahi anake, ahakoa he maha ngā mea e tīari ana, ā, ko te tahuritanga ki tētahi āhuahanga kāore i te tautoko i te pūrākau maha tūturu e pupuri ana i tētahi pūrākau me te whakawātea i te toenga. Hiko te pūrākau e hiahiatia ana e koe i mua i te tahuritanga, kaua e kitea i muri iho he mea ora tētahi.
E hiahiatia ana e te MPG he whakaaetanga whakawhiwhinga?
+
Kāore mō koe. Ko ngā pūkōrero e pā ana ki ngā pūtake ā-whakahaere, ā, ka whakaritea te whakaaetanga e ngā tāngata e whakarewa ana i ngā whakarerekētanga — te pūkoro, te whakataki, te pūnaha whakahaere — i mua i te tae atu o tētahi pūkōrero ki a koe. Ko te take o te āhua i ngā wāhi katoa o ngā pūrere, ko te take o te tīariari-kore-kore, ā, kāore e huri i te tahuritanga o tētahi pūkōrero kua whiwhi ki a koe.
