The broadcast receiving apparatus includes a signal processor which processes a broadcast signal of a tuned channel; a image generator which generates a manual fine tuning (MFT) image on which an optimal frequency of the tuned channel is to be tuned; a display which displays the MFT image; and a controller which, if a signal requesting adjustment is received, determines whether the broadcast signal is blocked and whether to re-tune the tuned channel using an adjusted optimal frequency based on a result of the blocking determination. The method includes processing a broadcast signal of a tuned channel; receiving a signal requesting adjustment; determining whether the broadcast signal is blocked; and determining whether to re-tune the channel using an adjusted optimal frequency based on a result of the determining. ## Claims ### Claim 1 A broadcast receiving apparatus comprising: a signal processor which processes a broadcast signal of a pre-tuned channel; an image generator which generates a manual fine tuning (MFT) image for performing manual fine tuning of an optimal frequency of a pre-tuned channel; a display which displays the MFT image; and a controller which, when a signal requesting manual fine tuning of the a pre-tuned channel is received, determines whether the pre-tuned channel is blocked and, if it is determined that the pre-tuned channel is blocked, controls the image generator to generate an information message and the display to display the information message and maintain blocking of the pre-tuned channel, wherein the information message indicates that MFT cannot be performed on the channel. ### Claim 2 (depends on 1) The broadcast receiving apparatus of claim 1, wherein after the signal is received, the controller controls the image generator to generate the MFT image and controls the display to display the MFT image. ### Claim 3 (depends on 1) The broadcast receiving apparatus of claim 1, wherein the controller generates one of an unwatchable image and a blue screen as the information message. ### Claim 4 (depends on 1) The broadcast receiving apparatus of claim 1, wherein the controller controls the tuner to re-tune the tuned channel based on an adjusted optimal frequency of the manual fine tuning, if it is determined that the pre-tuned channel is not blocked and the optimal frequency is adjusted through the displayed MFT. ### Claim 5 (depends on 1) The broadcast receiving apparatus of claim 1, wherein the controller controls the image generator and the display to generate and display the MFT image, if it is determined that the pre-tuned channel is not blocked, and controls the tuner to re-tune the pre-tuned channel based on an adjusted optimal frequency of the manual fine tuning, if the optimal frequency is adjusted through the displayed MFT. ### Claim 6 (depends on 5) The broadcast receiving apparatus of claim 5, further comprising a storage which stores the adjusted optimal frequency according to the channel. ### Claim 7 (depends on 1) The broadcast receiving apparatus of claim 1, wherein the signal requesting manual fine tuning is received from an external device. ### Claim 8 (depends on 1) The broadcast receiving apparatus of claim 1, wherein the controller generates one of an unwatchable image and a blue screen to control the signal processor and to maintain blocking of the broadcast signal, if it is determined that the pre-tuned channel is blocked. ### Claim 9 A broadcast receiving method comprising: processing a broadcast signal of a pre-tuned channel; receiving a signal requesting manual fine tuning (MFT) of an optimal frequency of the pre-tuned channel; determining whether the pre-tuned channel is blocked; and if it is determined that the pre-tuned channel is blocked, generating an information message and displaying the information message and maintaining blocking of the pre-tuned channel, wherein the information message indicates that MFT cannot be performed on the channel. ### Claim 10 (depends on 9) The broadcast receiving method of claim 9, further comprising: after receiving the signal requesting MFT, generating an MFT image on which the optimal frequency of the channel is adjusted; and displaying the MFT image. ### Claim 11 (depends on 9) The broadcast receiving method of claim 9, wherein generating the information message comprises: generating one of an unwatchable image and a blue screen, if it is determined that the pre-tuned channel is blocked. ### Claim 12 (depends on 10) The broadcast receiving method of claim 10, further comprising, if it is determined that the pre-tuned channel is not blocked: adjusting the optimal frequency through the displayed MFT image; and re-tuning the pre-tuned channel based on the adjusted optimal frequency. ### Claim 13 (depends on 9) The broadcast receiving method of claim 9, further comprising, if it is determined that the broadcast signal is not blocked: generating and displaying the MFT image on which the optimal frequency of the pre-tuned channel is to be adjusted; adjusting the optimal frequency through the displayed MFT image; and re-tuning the pre-tuned channel based on the adjusted optimal frequency. ### Claim 14 The broadcast receiving method of 13, further comprising, after adjusting the optimal frequency through the displayed MFT image and re-tuning the pre-tuned channel, storing the adjusted optimal frequency according to the pre-tuned channel. ### Claim 15 (depends on 9) The broadcast receiving method of claim 9, wherein the signal requesting MFT is received from an external device. ### Claim 16 (depends on 9) The broadcast receiving method of claim 9, wherein generating the information message comprises: generating one of an unwatchable image and a blue screen to maintain blocking of the broadcast signal, if it is determined that the pre-tuned channel is blocked. ### Claim 17 A broadcast receiving apparatus comprising: a signal processor which processes a broadcast signal of a channel; an image generator which generates a manual fine tuning (MFT) image; a display which displays the MFT image; and a controller which, when a signal requesting manual fine tuning of a pre-tuned channel is received, determines whether the broadcast signal of the pre-tuned channel is blocked, performs manual fine tuning to adjust an optimal frequency of the pre-tuned channel, and if it is determined that the broadcast signal is blocked, maintains blocking of the pre-tuned channel. ### Claim 18 (depends on 17) The broadcast receiving apparatus of claim 17, wherein if it is determined that the broadcast signal is not blocked, the controller retunes the pre-tuned channel based on the adjusted optimal frequency.
