rezultă că rata maximă de transfer pe cablu coaxial scade proporţional cu lungimea acestuia, de unde şi imaginile de scurtă durată de care vorbeai.
Pentru a recepţiona respectivele canale HD 720p vei avea nevoie probabil de un set top box cu ieşire component sau HDMI de la furnizorul CATV, care nu ştiu dacă este disponibil la RDS. Ştiu că UPC are o ofertă �n unele locaţii (unde s-a �nlocuit cablul coaxial cu fibră optică), vezi acest topic.
