"A report issued last week by Magna Global predicts that if network DVRs become a reality, DVR usage could skyrocket. Unlike set-top DVRs, which are already offered by several cable operators, a network DVR records virtually all programming on a central server in the cable system’s “headend.”
Theoretically, anybody who subscribes to digital cable could record whatever they wanted, without having to schedule an appointment with the cable guy or install a TiVo box.
According to Magna, network DVRs, if deployed this year, “would immediately make time-shifting technology available to 40 [percent] to 50 percent of a cable operator’s subscribers...significantly impacting how video content is consumed.” Magna Global’s director of industry analysis, Brian Wieser, who authored the report, said, “The possibility could be here a lot sooner than people think.”
