A broadcast signal processing apparatus and channel tuning method are provided. The method comprises a host including Open Cable Application Platform (OCAP) middleware for communication with an application program provided from a broadcasting station, and a memory for storing programs and data. The method further includes: transferring the input channel tuning key signal to the application program and a service context portion in the OCAP middleware; creating a virtual inner channel map in the service context portion, and obtaining channel information from the virtual inner channel map; performing channel tuning in advance using the obtained channel information; searching the channel information by the application program; requesting channel tuning to the OCAP middleware with the searched channel information; judging whether the searched channel information is identical to the obtained channel information; and completing channel tuning by taking the advance tuning if both channel information are identical to each other.
