The Downloadable Security Technical Advisory Cmte, which is to make recommendations to the FCC on downloadable security, should ensure that device manufacturers can differentiate retail products from MVPDs’ leased products, said a letter this week from Amazon, TiVo, Google, Free Press and others. They argue that limiting DSTAC’s scope to downloadable security alone would result in a “walled-garden approach that does not promote the vigorous competition and innovation envisioned by Sect 629.” There’s been some disagreement from DSTAC members on the issue, with several members, including DISH, Comcast and AT&T, complaining last month that the committee seems to be veering away from its mission. “The STELAR legislation clearly limits the DSTAC to recommendations on downloadable security and downloadable security alone. Congress rejected a proposal to expand that mission in the manner some want to do now. To remain true to its Congressional mandate, the FCC must do the same,” NCTA said Tues. DSTAC is scheduled to meet Wed to receive presentations from working groups on security and device platforms.
