Open cable broadcast processing apparatus and control method thereof, and cable card software upgrading method for open cable system

摘要

An open cable broadcast processing apparatus and control methods are provided. The broadcast processing apparatus includes a tuner to tune a cable signal supplied from a delivery system, an interface which is connected with a cable card descrambling the cable signal supplied through the tuner; and a controller which controls the tuner to change a reception channel based on received channel information when the channel information is received from the cable card through the interface to upgrade software, and controls not to change an operation corresponding to an operational change command when the operational change command is input to request an operational change. Thus, a channel supplying software information is prevented from being changed while upgrading software of a cable card and the upgrading operation is completed without interruption.
