I waihangatia i te tau kotahi rau e waru tekau mā rua, ka kitea tonutia i te nuinga o nga kāinga i tēnei rā. Ka tuku tohu ororongo, ataata hoki. Ko te pūtaukī o RCA e tautohe ana mō Radio Corporation of America.

I te taketake, i hoahoatia te mono RCA hei whakakapi i ngā mono waea tawhito o ngā whakawhitinga waea ā-ringa.
I whakarewaina i runga i te mākete i te wā he whetū nga rīpene me ngā VCR.

Mā te tūhonotanga RCA ka taea te tuku tohu ataata me ngā tohu ororongo (i te mono, tīwharawhara rānei) mā tētahi taura e whai ana i ngā aho e rua, e ai ki tētahi aratau taritenga, mamati rānei.
He iti rawa te hua, kei te hototahi tonu ki te nuinga o ngā hōputu ataata e tukua ana.

He rerekē te tae o ngā tūhono RCA i runga anō i tā rātou whakamahinga.
Ko ngā tūhono RCA e kōmakatia ana mā te tae, kōwhai mō te ataata hiato, whero mō te hongere ororongo matau, me te mā, pango rānei mō te hongere tīwharawhara mauī.
E noho ana tēnei takitoru (takirua rānei) o ngā kuhunga ki muri o ngā taputapu ororongo, ataata katoa hoki.

Mēnā he tohu ataata hiato, he kōwhai te tūhono. Ka taea hoki e te tūhono RCA te tuku tohu wae ataata, e mōhiotia ana hoki ko YUV, YCrCb rānei.
Ko ngā tūhono e 3 e whakamahia ana mō tēnei momo tohu he tae whero, kākāriki, kikorangi hoki.

Ko te paerewa YUV (e kiia ana hoki ko CCIR 601), i karangatia i mua ko YCrCb (Y Cr NW), he tauira whakaaturanga tae kua whakatapua ki te ataata tairitenga.

E ai ki tētahi wae motuhake aratau tarenga ataata mā te whakamahi i ngā taura rerekē e toru hei tuku mōhiohio (tīahoaho) (tīahoaho) me ngā mōtete e rua ngā kōrerorero (tae).
Ko tēnei te hōputu i whakamahia ki ngā paerewa PAL (Raina Huringa Wāhanga) me SECAM (Tae Raupapa me te Pūmahara).

E tohu ana te tawhā Y i te rārangitanga (i.e. mōhiohio pango me te mā), i a koe me V e tohu ana i te kōrerorero, i.e. mōhiohio mō te tae.
I hangaia tēnei tauira kia tukuna atu ngā mōhiohio tae ki ngā IRI tae, me te whakarite kia whakaatu tonu ngā TT pango me te mā tīariari i tētahi atahanga oro-kiwikiwi.

Anei ngā pātahitanga e hono ana i Y ki R, G, me B, ko koe ki R me te rārangi, kātahi anō ko V ki te B me te rangirua :

      Y = 0.2R + 0.587 G + 0.114 B
U = -0.147R - 0.289 G + 0.436B = 0.492(B - Y)
V = 0.615R -0.515G -0.100B = 0.877(R-Y)


Nā reira i ētahi wā e whakaingoatia ana a U i te Cr me V, nō reira ko te YCrCb tautuhi.
Ko te tikanga, ko te tūhononga YUV e ai ki te whakamahinga o ngā taura RCA e toru o te tae kākāriki, kikorangi, whero hoki :

Ka tuku te tūhononga YUV i te kounga ataata arotau mā te tuku i ngā raina 576 katoa o te atahanga, me te kore whiriwhiringa (kia kotahi te haere).

E mōhio ana, he tino utu tēnei tūhononga, engari he hē anō tōna. Nā te mea kei te whakamahia ia taura hei tuku i tētahi tohu kotahi, arā, he maha ngā taura e hiahiatia ana i ētahi pūrere.
He momonga anō : tōna tautiaki haumaru-kore, he māmā noa iho te motu o te taura, nō reira ka whakatokona ngā hoapā hē.
Anō hoki : ka puta mai pea te turituri motukore mēnā he wāhanga o te mono mai i te kōhao.

Ka whakamahia te hōputu S/TAKAF (pūtaukī mō te Tauwhāinga Mamati a Kapapa/Piripihi), i te IEC 958 rānei hei whakawhiti i ngā raraunga ororongo mamati.
Ka taea te whakaaro i tēnei paerewa i hoahoatia e Ratonga Me Piripi te putanga kiritaki o te hōputu ororongo mamati ngaio o AES/EBU. I tautuhia i te tau1989.

He rerekē ngā momo paerewa S/NEIF :

- Ko te tūhono RCA (mā te taura nōrearea (kapa)) he 75 Ω.
- Hononga hononga (mā te tūhononga ōmata). Ko te painga matua o tēnei hōputu kai roto i tōna āraitanga katoa ki nga āhuatanga autō ā-hiko.
- Tūhono Hononga-Iti (mā te tākainga ōmata). E ōrite ana ki te hangarau i mua, ko ngā huringa pūhono anake, te āhua nei he pirita iti 3.5mm paerewa (0.5mm poto ake hei ārai i te mahi hē me te pā ki te LED).
