Muri ibyo bihe byombi, amakuru ya tereviziyo yoherejwe mu gihe cyo guhagarikwa guhagaritse, igice cyagenwe kugirango urumuri rwa elegitoronike rugaruke ruva munsi ya ecran rusubira hejuru ya buri kintu cyerekana ishusho (gihuye nigihe cyo kohereza imirongo 25 muri buri gice cya PAL cyangwa SECAM ), kandi buri murongo wakoresheje watangaga umubare uteganijwe wa byite buri cyiciro: 40 bytes kuri sisitemu yuburayi, 32 muri Amerika.
