The Federal Communications Commission moved Thursday to open up the retail market for companies that provide cable set-top boxes and digital video recorders.At Thursday's open meeting, the FCC issued an order that would promote competition in the marketplace for set-top boxes by ensuring retail devices such as TiVo have the same access to prescheduled programming as cable providers. The order would also make CableCARD pricing and billing more transparent, streamline the installation process, and ease requirements on manufacturers and operators upgrading their equipment.
