a management unit configured to manage an available recording capacity of the storage unit; a selection unit configured to, in a case where the available recording capacity is less than a predetermined amount, (1) select a multi-view program content data broadcasted by a plurality of channels including content data associated with each other from among the program content data in the storage unit if there is the multi-view program content data in the storage unit, and (2) select a non multi-view program content data if there is no multi-view program content data in the storage unit, wherein the multi-view program content data comprises content data of at least a main channel and a sub channel; a display control unit configured to, (1) if the multi-view program content data is selected by the selection unit, display information of the main channel and the sub channel of the selected multi-view program content data and inquire a user whether to permit the deletion of the content data of the sub channel while keeping the content data of the main channel of the selected multi-view content, and (2) if the non multi-view program content data is selected by the selection unit, display information of the non multi-view program content data and inquire a user whether to permit the deletion of the selected non multi-view program content data; and a deletion unit configured to, (1) if the user permits the deletion of the content data of the sub channel while keeping the content data of the main channel of the selected multi-view content, delete content data of the sub channel included in the selected multi-view program content data from the storage unit, and (2) if the user permits the deletion of non multi-view program content data, delete the selected non multi-view program content data from the storage unit. ### Claim 2 (depends on 1) The recording apparatus according to claim 1, further comprising a display control unit configured to indicate the multi-view program content data of the program content data stored in the storage unit such that the multi-view program content data is identifiable compared to the non multi-view program content data, wherein the deletion unit selects the multi-view program content data in response to receiving a selection instruction from the user. ### Claim 3 (depends on 1) The recording apparatus according to claim 1, wherein the deletion unit deletes content data of a channel designated by a user from the storage unit. ### Claim 4 (depends on 1) The recording apparatus according to claim 1, wherein the deletion unit deletes content data of a channel having a low user preference from the storage unit. ### Claim 5 (depends on 1) The recording apparatus according to claim 1, wherein, when a plurality of multi-view program content data are stored in the storage unit, the deletion unit selects one of the plurality of multi-view program content data having oldest broadcast date and time out of the plurality of multi-view program content data and deletes content data of at least one but not all of the plurality of channels included in the selected multi-view program content data from the storage unit. ### Claim 6 (depends on 1) The recording apparatus according to claim 1, wherein, when a plurality of multi-view program content data are stored in the storage unit, the deletion unit selects one of the plurality of multi-view program content data that is designated by a user and deletes content data sub channel included in the selected multi-view program content data from the storage unit. ### Claim 7 (depends on 1) The recording apparatus according to claim 1, further comprising a stream generation unit configured to generate a partial transport stream from the content data of the main channel included in the selected multi-view program content data. ### Claim 8 A method for controlling a recording apparatus, the method comprising: recording program content data transmitted in a broadcast signal; storing the program content data in a storage unit; managing an available recording capacity of the storage unit; selecting, in a case where the available recording capacity is less than a predetermined amount, (1) a multi-view program content data broadcasted by a plurality of channels including content data associated with each other from among the program content data in the storage unit if there is the multi-view program content data in the storage unit, and (2) a non multi-view program content data if there is no multi-view program content data in the storage unit, wherein the multi-view program content data comprises content data of at least a main channel and a sub channel; displaying information of the main channel and the sub channel of the selected multi-view program content data and inquiring a user whether to permit the deletion of the content data of the sub channel while keeping the content data of the main channel of the selected multi-view content in a case where the multi-view program content data is selected by the selection unit, and displaying information of the non multi-view program content data and inquiring a user whether to permit the deletion of the selected non multi-view program content data in a case where the non multi-view program content data is selected by the selection unit; and deleting, in a case where the user permits the deletion of the content data of the sub channel while keeping the content data of the main channel of the selected multi-view content, content data of the sub channel included in the selected multi-view program content data from the storage unit, and deleting, in a case where the user permits the deletion of non multi-view program content data, the selected non multi-view program content data from the storage unit. ### Claim 9 (depends on 8) The method according to claim 8, further comprising indicating, by a display control unit, the multi-view program content data of the program content data stored in the storage unit such that the multi-view program content data is identifiable compared to the non multi-view program content data, wherein the deleting step selects the multi-view program content data in response to receiving a selection instruction from the user. ### Claim 10 (depends on 8) The method according to claim 8, wherein the deleting step deletes content data of a channel designated by a user from the storage unit. ### Claim 11 (depends on 8) The method according to claim 8, wherein the deleting step deletes content data of a channel having a low user preference from the storage unit. ### Claim 12 (depends on 8) The method according to claim 8, wherein, when a plurality of multi-view program content data are stored in the storage unit, the deleting step selects one of the plurality of multi-view program content data having oldest broadcast date and time out of the plurality of multi-view program content data and deletes content data of at least one but not all of the plurality of channels included in the selected multi-view program content data from the storage unit. ### Claim 13 (depends on 8) The method according to claim 8, wherein, when a plurality of multi-view program content data are stored in the storage unit, the deleting step selects one of the plurality of multi-view program content data that is designated by a user and deletes content data the sub channel included in the selected multi-view program content data from the storage unit. ### Claim 14 (depends on 8) The method according to claim 8, further comprising generating a partial transport stream from the content data of the main channel included in the selected multi-view program content data.
